The unit of this field is nanoseconds. If Bit [0] is set, it indicates memory contents will be preserved in the specified power state If Bit [0] is clear, it indicates memory contents will be lost in the specified power state e. If Bit [1] is set, this field indicates that given memory power state entry transition needs to be triggered explicitly by OSPM by calling the Set Power State command. If Bit [1] is clear, this field indicates that given memory power state entry transition is automatically implemented in hardware and does not require a OSPM trigger.

The role of OSPM in this case is to ensure that the corresponding memory region is idled from a software standpoint to facilitate entry to the state. Not meaningful for MPS0 – write it for this table.

If Bit [1] is set, this field indicates that given memory power state exit needs to be explicitly triggered by the OSPM before the memory can be accessed. System behavior is undefined if OSPM or other software agents attempt to access memory that is currently in a low power state. If Bit [1] is clear, this field indicates that given memory power state is exited automatically on access to the memory address range corresponding to the memory power node.

The role of OSPM software in handling such autonomous memory power states is to vacate the use of such memory regions when possible in order to allow hardware to effectively save power.

The platform may accept the command and enter the state immediately in which case it must return command completion with SUCCESS b status. Platform firmware may have regions of memory reserved for its own use that are unavailable to OSPM for allocation. Memory nodes where all or a portion of the memory is reserved by platform firmware may pose a problem for OSPM because it does not know whether the platform firmware reserved memory is in use.

If the platform firmware reserved memory impacts the ability of the memory power node to enter memory power state s , the platform must indicate to OSPM by clearing the Power Managed Flag – see Table 5. This allows OSPM to ignore such ranges from its memory power optimization.

The later sections provide sample NUMA configurations and explain the policy for various memory power nodes. The hot pluggable memory regions are described using memory device objects see Section 9.

The memory power state table MPST is a static structure created for all memory objects independent of hot plug status online or offline during initialization.

This allows OS to optimize the power manageable memory power nodes for optimal power savings. OSes can assume that memory ranges that belong to memory power nodes that are power manageable as indicated by the flag are interleaved in a manner that does no impact the ability of that range to enter power managed states.

For example, such memory is not cacheline interleaved. Reference to memory in this document always refers to host physical memory. For virtualized environments, this requires hypervisors to be responsible for memory power management. Hypervisors also have the ability to create opportunities for memory power management by vacating appropriate host physical memory through remapping guest physical memory.

This table describes the memory topology of the system to OSPM, where the memory topology can be logical or physical. The topology is provided as a hierarchy of memory devices where the top level memory devices e. DIMMs associated with a parent memory device. The number of top level Memory Device structures that immediately follow. A zero in this field indicates no Memory Device structures follow. A list of memory device structures for the platform. Length in bytes for this structure.

The Boot Graphics Resource Table BGRT is an optional table that provides a mechanism to indicate that an image was drawn on the screen during boot, and some information about the image. The table is written when the image is drawn on the screen. This should be done after it is expected that any firmware components that may write to the screen are done doing so and it is known that the image is the only thing on the screen.

If the boot path is interrupted e. A 4-byte bit unsigned long describing the display X-offset of the boot image. X, Y display offset of the top left corner of the boot image. The top left corner of the display is at offset 0, 0. A 4-byte bit unsigned long describing the display Y-offset of the boot image. The version field identifies which revision of the BGRT table is implemented.

The version field should be set to 1. The Image type field contains information about the format of the image being returned. If the value is 0, the Image Type is Bitmap. The Image Address contains the location in memory where an in-memory copy of the boot image can be found. The image should be stored in EfiBootServicesData, allowing the system to reclaim the memory when the image is no longer needed.

The Image Offset contains 2 consecutive 4 byte unsigned longs describing the X, Y display offset of the top left corner of the boot image. This section describes the format of the Firmware Performance Data Table FPDT , which provides sufficient information to describe the platform initialization performance records.

This information represents the boot performance data relating to specific tasks within the firmware boot process. The FPDT includes only those mileposts that are part of every platform boot process:. End of reset sequence Timer value noted at beginning of platform boot firmware initialization – typically at reset vector.

A performance record is comprised of a sub-header including a record type and length, and a set of data. The format of the data is specific to the record type. In this manner, records are only as large as needed to contain the specific type of data to be conveyed.

Note that unless otherwise specified, multiple records are permitted for a given type, because some events may occur multiple times during the boot process. This value is updated if the format of the record type is extended. Any changes to a performance record layout must be backwards-compatible in that all previously defined fields must be maintained if still applicable, but newly defined fields allow the length of the performance record to be increased.

Previously defined record fields must not be redefined, but are permitted to be deprecated. The table below describes the various Runtime Performance records and their corresponding Record Types. Performance record showing basic performance metrics for critical phases of the firmware boot process. The record pointer is a required entry in the FPDT for any system, and the pointer must point to a valid static physical address.

The Firmware Basic Boot Performance Data Record contains timer information associated with final OS loader activity, as well as data associated with boot time starting and ending information.

Timer value logged at the beginning of firmware image execution. This may not always be zero or near zero.

Timer value logged just prior to loading the OS boot loader into memory. For non-UEFI compatible boots, this field must be zero. Timer value logged just prior to launching the currently loaded OS boot loader image.

All event entries must be initialized to zero during the initial boot sequence, and overwritten during the platform runtime firmware S3 resume sequence. Length of the S3 Performance Table. This size would at minimum include the size of the header and the Basic S3 Resume Performance Record. Timer recorded at the end of platform runtime firmware S3 resume, just prior to handoff to the OS waking vector. Average timer value of all resume cycles logged since the last full boot sequence, including the most recent resume.

Note that the entire log of timer values does not need to be retained in order to calculate this average. The bit physical address at which the Counter Control block is located.

Flags for the secure EL1 timer defined below. This value is optional, as an operating system executing in the non-secure world EL2 or EL1 will ignore the content of this field. The bit physical address at which the Counter Read block is located. This field is mandatory for systems implementing ARMv8. For systems not implementing ARMv8. Flags for the virtual EL2 timer defined below. Array of Platform Timer Type structures describing memory-mapped Timers available on this platform.

These structures are described in the sections below. These timers are in addition to the per-processor timers described above them in the GTDT. The first byte of each structure declares the type of that structure and the second and third bytes declare the length of that structure.

The GT Block is a standard timer block that is mapped into the system address space. Flags for the GTx physical timer.

Flags for the GTx virtual timer, if implemented. Interleave Structure s see Section 5. Flush Hint Address Structure s see Section 5. Platform Capabilities Structure see Section 5. The following figure illustrates the above structures and how they are associated with each other. This allows OSPM to ignore unrecognized types. Platform is allowed to implement this structure just to describe system physical address ranges that describe Virtual CD and Virtual Disk.

Value of 0 is Reserved and shall not be used as an index. Integer that represents the proximity domain to which the memory belongs. This number must match with corresponding entry in the SRAT table. Opaque cookie value set by platform firmware for OSPM use, to detect changes that may impact the readability of the data. Refer to the UEFI specification for details.

Handle i. There could be multiple regions within the device corresponding to different address types. Also, for a given address type, there could be multiple regions due to interleave discontinuity. Typically, only block region requires the interleave structure since software has to undo the effect of interleave.

This structure describes the memory interleave for a given address range. Since interleave is a repeating pattern, this structure only describes the lines involved in the memory interleave before the pattern start to repeat.

Index must be non-zero. Line SPA is naturally aligned to the Line size. Length in bytes for entire structure. The length of this structure is either 32 bytes or 80 bytes.

The length of the structure can be 32 bytes only if the Number of Block Control Windows field has a value of 0. Byte 1 of this field is reserved. Identifier for the NVDIMM non-volatile memory subsystem controller, assigned by the non-volatile memory subsystem controller vendor. Revision of the NVDIMM non-volatile memory subsystem controller, assigned by the non-volatile memory subsystem controller vendor.

SPD byte Validity of this field is indicated in Valid Fields Bit [0]. Fields that follow this field are valid only if the number of Block Control Windows is non-zero. In Bytes. Logical offset. Refer to Note. Logical offset in bytes. Refer to Note1. Bit [0] set to 1 to indicate that the Block Data Windows implementation is buffered.

The content of the data window is only valid when so indicated by Status Register. The logical offset is with respect to the device, not with respect to system physical address space. Software should construct the device address space accounting for interleave before applying the block control start offset. Logical offset in bytes see note below. The address of the next block is obtained by adding the value of this field to Size of Block Data Window.

The logical offset is with respect to the device not with respect to system physical address space. Software should construct the device address space accounting for interleave before applying the Block Data Window start offset. Software needs an assurance of durability i. Note that the platform buffers do not include processor cache s! Processors typically include ISA to flush data out of processor caches. Software is allowed to write up to a cache line of data.

The content of the data is not relevant to the functioning of the flush hint mechanism. The bit index of the highest valid capability implemented by the platform. The subsequent bits shall not be considered to determine the capabilities supported by the platform.

This format matches the order of SPD bytes to from low to high i. The table is applicable to systems where a secure OS partition and a non-secure OS partition co-exist. A secure device is a device that is protected by the secure OS, preventing accesses from non-secure OS. The table provides a hint as to which devices should be protected by the secure OS. The enforcement of the table is provided by the secure OS and any pre-boot environment preceding it.

The table itself does not provide any security guarantees. It is the responsibility of the system manufacturer to ensure that the operating system is configured to enable security features that make use of the SDEV table. Device is listed in SDEV. This provides a hint that the device should be always protected within the secure OS.

For example, the secure OS may require that a device used for user authentication must be protected to guard against tampering by malicious software. This provides a hint that the device should be initially protected by the secure OS, but it is up to the discretion of the secure OS to allow the device to be handed off to the non-secure OS when requested.

Any OS component that expected the device to be operating in secure mode would not correctly function after the handoff has been completed. For example, a device may be used for variety of purposes, including user authentication. If the secure OS determines that the necessary components for driving the device are missing, it may release control of the device to the non-secure OS. In this case, the device cannot be used for secure authentication, but other operations can correctly function.

Device not listed in SDEV. For example, the status quo is that no hints are provided. Any OS component that expected the device to be in secure mode would not correctly function. Reserved for future use. For forward compatibility, software skips structures it does not comprehend by skipping the appropriate number of bytes indicated by the Length field.

All new device structures must include the Type, Flags, and Length fields as the first 3 fields respectively. Length of the list of Secure Access Components data. Identification Based Secure Access Component. A minimum of one is required for a secure device. When there are multiple Identification Components present, priority is determined by list order.

Memory Based Secure Access Component. For forward compatibility, software skips structures that it does not comprehend by skipping the appropriate number of bytes indicated by the Length field. All new device structures must include the Type, Flags, and Length fields as the first 3 fields, respectively. Even numbered offsets contain the Device numbers, and odd numbered offsets contain the Function numbers.

Each subsequent pair resides on the bus directly behind the bus of the device identified by the previous pair. The software is expected to use this information as a hint for optimization, or when the system has heterogeneous memory. Memory Proximity Domain Attributes Structure s. Describes attributes of memory proximity domains. Describes the memory access latency and bandwidth information from various memory access initiator proximity domains.

The optional access mode and transfer size parameters indicate the conditions under which the Latency and Bandwidth are achieved. Memory Side Cache Information Structure s. Describes memory side cache information for memory proximity domains if the memory side cache is present and the physical device SMBIOS handle forms the memory side cache.

Memory side cache allows to optimize the performance of memory subsystems. When the software accesses an SPA, if it is present in the near memory hit it would be returned to the software, if it is not present in the near memory miss it would access the next level of memory and so on.

The Level n Memory acts as memory side cache to Level n-1 Memory and Level n-1 memory acts as memory side cache for Level n-2 memory and so on.

If Non-Volatile memory is cached by memory side cache, then platform is responsible for persisting the modified contents of the memory side cache corresponding to the Non-Volatile memory area on power failure, system crash or other faults. This structure describes the system physical address SPA range occupied by the memory subsystem and its associativity with processor proximity domain as well as hint for memory usage.

Bit [0]: set to 1 to indicate that data in the Proximity Domain for the Attached Initiator field is valid. Bit [1]: Reserved. Previously defined as Memory Proximity Domain field is valid. Deprecated since ACPI 6. Bit [2]: Reserved. Previously defined as Reservation Hint. Bits [] : Reserved. This field is valid only if the memory controller responsible for satisfying the access to memory belonging to the specified memory proximity domain is directly attached to an initiator that belongs to a proximity domain.

In that case, this field contains the integer that represents the proximity domain to which the initiator Generic Initiator or Processor belongs. Note: this field provides additional information as to the initiator node that is closest as in directly attached to the memory address ranges within the specified memory proximity domain, and therefore should provide the best performance.

The latency and bandwidth numbers represented in this structure correspond to specification rated latency and bandwidth for the platform. The represented latency is determined by aggregating the specification rated latencies of the memory device and the interconnects from initiator to target.

The represented bandwidth is determined by the lowest bandwidth among the specification rated bandwidth of the memory device and the interconnects from the initiator to target. Multiple table entries may be present, based on qualifying parameters, like minimum transfer size, etc. They may be ordered starting from most- to least-optimal performance.

Unless specified otherwise in the table, the reported numbers assume naturally aligned data and sequential access transfers. Indicates total number of Proximity Domains that can initiate memory access requests to other proximity domains.

Indicates total number of Proximity Domains that can act as target. This is typically the Memory Proximity Domains. Base unit for Matrix Entry Values latency or bandwidth.

Base unit for latency in picoseconds. This field shall be non-zero. The Flag field in this table allows read latency, write latency, read bandwidth and write bandwidth as well as Memory Hierarchy levels, minimum transfer size and access attributes.

Hence this structure could be repeated several times, to express all the appropriate combinations of Memory Hierarchy levels, memory and transfer attributes expressed for each level.

If multiple structures are present, they may be ordered starting from most- to least-optimal performance. If either latency or bandwidth information is being presented in the HMAT, it is required to be complete with respect to initiator-target pair entries.

For example, if read latencies are being included in the SLLBI, then read latencies for all initiator-target pairs must be present. If some pairs are incalculable, then the read latency dataset must be omitted entirely. It is acceptable to provide only a subset of the possible datasets. For example, it is acceptable to provide read latencies but omit write latencies. This provides OSPM a complete picture for at least one set of attributes, and it has the choice of keeping that data or discarding it.

System memory hierarchy could be constructed to have a large size of low performance far memory and smaller size of high performance near memory. The Memory Side Cache Information Structure describes memory side cache information for a given memory domain. The software could use this information to effectively place the data in memory to maximize the performance of the system memory that use the memory side cache.

Integer that represents the memory proximity domain to which the memory side cache information applies. Implementation Note: A proximity domain should contain only one set of memory attributes.

If memory attributes differ, represent them in different proximity domains. If the Memory Side Cache Information Structure is present, the System Locality Latency and Bandwidth Information Structure shall contain latency and bandwidth information for each memory side cache level. This is intended as a standard mechanism for the OSPM to notify the platform of a fatal crash e. This table is intended for platforms that provide debug hardware facilities that can capture system info beyond the normal OS crash dump.

This trigger could be used to capture platform specific state information e. This type of debug feature could be leveraged on mobile, client, and enterprise platforms. Certain platforms may have multiple debug subsystems that must be triggered individually. This table accommodates such systems by allowing multiple triggers to be listed.

To give hardware vendors flexibility in choosing their implementation, ACPI uses tables to describe system information, features, and methods for controlling those features. These tables list devices on the system board or devices that cannot be detected or power managed using some other hardware standard, plus their capabilities as described in ACPI Concepts They also list system capabilities such as the sleeping power states supported, a description of the power planes and clock sources available in the system, batteries, system indicator lights, and so on.

This enables OSPM to control system devices without needing to know how the system controls are implemented. The ACPI system description table architecture is defined, and the role of OEM-provided definition blocks in that architecture is discussed.

All system description tables start with identical headers. The primary purpose of the system description tables is to define for OSPM various industry-standard implementation details. Such definitions enable various portions of these implementations to be flexible in hardware requirements and design, yet still provide OSPM with the knowledge it needs to control hardware directly.

The data within this table includes various fixed-length entries that describe the fixed ACPI features of the hardware. The relationship between these tables is shown in Description Table Structures. These tables contain one or more physical pointers to other system description tables that provide various information about the system.

When OSPM follows a physical pointer to another table, it examines each table for a known signature. Based on the signature, OSPM can then interpret the implementation-specific data within the description table. The purpose of the FADT is to define various static system information related to configuration and power management.

All definition blocks loaded by OSPM combine to form one namespace that represents the platform. Their values may be static or dynamic. Definition Blocks can either define new system attributes or, in some cases, build on prior definitions. A Definition Block can be loaded from system memory address space. One use of a Definition Block is to describe and distribute platform version changes. Definition blocks enable wide variations of hardware platform implementations to be described to the ACPI-compatible OS while confining the variations to reasonable boundaries.

Definition blocks enable simple platform implementations to be expressed by using a few well-defined object names. Some operators perform simple functions and others encompass complex functions. The power of the Definition Block comes from its ability to allow these operations to be glued together in numerous ways, to provide functionality to OSPM. The operators present are intended to allow many useful hardware designs to be ACPI-expressed, not to allow all hardware designs to be expressed.

This translation can take the form of the addition or subtraction of an offset. The address the processor places on the processor bus will be known here as the processor-relative address. Unless otherwise noted, all addresses used within this section are processor-relative addresses. For example, consider a platform with two root PCI buses. The platform designer has several choices. Industry standard PCs do not provide address space translations because of historical compatibility issues.

System Description Table Header. All numeric values in ACPI-defined tables, blocks, and structures are always encoded in little endian format. Signature values are stored as fixed-length strings. For future expansion, all data items marked as reserved in this specification have strict meanings. This section lists software requirements for reserved fields.

OEM implementations of software and AML code return only defined values and do not return reserved values. Software preserves the value of all reserved bits in hardware control registers by writing back read values. Software handles ignored bits in ACPI hardware registers the same way it handles reserved bits in these same types of registers. All versions of the ACPI tables must maintain backward compatibility.

To accomplish this, modifications of the tables consist of redefinition of previously reserved fields and values plus appending data to the 1. Modifications of the ACPI tables require that the version numbers of the modified tables be incremented. The length field in the tables includes all additions and the checksum is maintained for the entire length of the table. Addresses used in the ACPI 1. This was targeted at the IA environment.

Newer architectures require addressing mechanisms beyond that defined in ACPI 1. ACPI defines the fixed hardware low-level interfaces as a means to convey to the system OEM the minimum interfaces necessary to achieve a level of capability and quality for motherboard configuration and system power management. Additionally, the definition of these interfaces, as well as others defined in this specification, conveys to OS Vendors OSVs developing ACPI-compatible operating systems, the necessary interfaces that operating systems must manipulate to provide robust support for system configuration and power management.

While the definition of low-level hardware interfaces defined by ACPI 1. Unfortunately, the nature of SMM-based code makes this type of OS independent implementation difficult if not impossible to debug. As such, this implementation approach is not recommended.

In some cases, Functional Fixed Hardware implementations may require coordination with other OS components. As such, an OS independent implementation may not be viable. OS-specific implementations of functional fixed hardware can be implemented using technical information supplied by the CPU manufacturer. The downside of this approach is that functional fixed hardware support must be developed for each OS. In some cases, the CPU manufacturer may provide a software component providing this support.

In other cases support for the functional fixed hardware may be developed directly by the OS vendor. The hardware register definition was expanded, in ACPI 2. This is accomplished through the specification of an address space ID in the register definition see Generic Address Structure for more information. When specifically directed by the CPU manufacturer, the system firmware may define an interface as functional fixed hardware by indicating 0x7F Functional Fixed Hardware , in the address space ID field for register definitions.

It is emphasized that functional fixed hardware definitions may be declared in the ACPI system firmware only as indicated by the CPU Manufacturer for specific interfaces as the use of functional fixed hardware requires specific coordination with the OS vendor. Only certain ACPI-defined interfaces may be implemented using functional fixed hardware and only when the interfaces are common across machine designs for example, systems sharing a common CPU architecture that does not support fixed hardware implementation of an ACPI-defined interface.

OEMs are cautioned not to anticipate that functional fixed hardware support will be provided by OSPM differently on a system-by-system basis. The use of functional fixed hardware carries with it a reliance on OS specific software that must be considered. OEMs should consult OS vendors to ensure that specific functional fixed hardware interfaces are supported by specific operating systems. The size in bits of the given register. When addressing a data structure, this field must be zero.

The bit offset of the given register at the given address. The bit address of the data structure or register in the given address space relative to the processor. See below for specific formats. The bit physical memory address relative to the processor of the register.

This can also be found as part of the DCE 1. This is the checksum of the fields defined in the ACPI 1. This includes only the first 20 bytes of this table, bytes 0 to 19, including the checksum field. These bytes must sum to zero. The revision of this structure. Larger revision numbers are backward compatible to lower revision numbers. The ACPI version 1. It does not include the Length field and beyond.

The current value for this field is 2. The length of the table, in bytes, including the header, starting from offset 0. This field is used to record the size of the entire table. This field is not available in the ACPI version 1. The Signature field in this table determines the content of the system description table. The revision of the structure corresponding to the signature field for this table.

Larger revision numbers are backward compatible to lower revision numbers with the same signature. This field is particularly useful when defining a definition block to distinguish definition block functions. Vendor ID of utility that created the table. Revision of utility that created the table. The intent of these fields is to allow for a binary control system that support services can use. Because many support functions can be automated, it is useful when a tool can programmatically determine which table release is a compatible and more recent revision of a prior table on the same OEMID and OEM Table ID.

Table 5. These system description tables may be defined by ACPI and documented within this specification, or they may simply be reserved by ACPI and defined by other industry specifications.

For tables defined by other industry specifications, the ACPI specification acts as gatekeeper to avoid collisions in table signatures. Requests to reserve a 4-byte alphanumeric table signature should be sent to the email address info acpi. Tables defined outside of the ACPI specification may define data value encodings in either little endian or big endian format.

For the purpose of clarity, external table definition documents should include the endian-ness of their data value encodings. Section 5. Section Arm Error Source Table. Component Distance Information Table.

Adobe Creative Suite CS is a discontinued software fesigner of graphic designvideo editingand web development applications developed by Adobe Systems. On May 6,Adobe announced that CS6 affinit be the last version of the Creative Affinity designer x86 free, [2] [3] [4] and that future versions of their creative software would only be available via their Adobe Affinity designer x86 free Cloud subscription model.

Adobe also announced that it would continue to support CS6 and would provide bug fixes and security updates through тебя folder locker download for windows 10 действительно next major upgrades of both Mac and Windows operating systems as affiinty The following table shows the different details of the core applications in the various Adobe Creative Suite editions.

Each edition may come with all these apps included or only a subset. Adobe Stock launched in Adobe sold Creative Suite applications in several different combinations called “editions”, these included:.

Adobe Prelude and Adobe Encore are not released as standalone products. Adobe Encore is available as part of Adobe Premiere Pro. In Marchit was reported fref Adobe adobe cs6 tryout free no longer sell boxed copies of the Creative Suite software, instead offering digital downloads and monthly subscriptions.

Creative Suite helped InDesign become the dominant publishing software, replacing QuarkXPressbecause customers who purchased the suite for Photoshop and Illustrator received InDesign at no additional cost. Adobe shut down the “activation” servers for CS2 in Decembermaking it impossible for licensed users affinity designer x86 free reinstall the software if needed. In response to complaints, Adobe then made available for download a version of CS2 that did not require online activation, and published a serial number to activate it offline.

Affinity designer x86 free Creative Suite Production Studio previously Adobe Video Collection was a suite of programs for acquiring, editing, and distributing digital video and audio that was released during the same timeframe as Adobe Creative Suite vesigner.

The suite was available in standard and premium editions. Affinity designer x86 free Studio was a suite of programs designed for web content creation designed affinity designer x86 free distributed by Macromedia. After Adobe ‘s acquisition of Macromedia, Macromedia Studio 8 was replaced, modified, and integrated into two editions of the Adobe Creative Suite family of software from version 2.

Frree Macromedia applications were absorbed into existing Adobe products, e. FreeHand has been replaced with Adobe Illustrator. Director and ColdFusion are not part of Adobe Creative Suite and will only be available as standalone products.

The final version affinity designer x86 free Macromedia Studio released include:. Adobe Creative Suite 3 CS3 was announced on March affinity designer x86 free, ; it introduced universal binaries for all major programs for the Apple Microsoft office word 2007 free download pc free download[19] as well as including all of the core applications from Macromedia Studio and Production Studio.

Some Creative Suite programs also began using the Presto layout engine used in the Opera web browser. Adobe began selling Affinity designer x86 free applications in six http://replace.me/29411.txt combinations desiner “editions. The latest released CS3 version was version 3. CS3 included several programs, including DreamweaverFlash Professionaland Fireworks that were developed by Macromedia frse, a former rival acquired by Adobe in Adobe dropped the following programs that were previously included in CS2 from the CS3 software bundles: [22].

Adobe had announced that it would continue to develop Audition as a standalone product, while GoLive had been discontinued. Adobe GoLive 9 was released as a standalone product on June 10, Adobe Audition 3 was announced as a standalone product on September 6, Adobe ссылка на подробности discontinued ImageReady and had replaced it with Fireworks, with some of Free features integrated into Photoshop.

Audition became part of the Creative Suite again in CS5. Adobe CS4 was also developed to perform better under bit and multi-core processors. Two programs were dropped from the CS4 line-up: Adobe Frera vector keying application which utilizes image analysis technology to produce http://replace.me/5251.txt quality chroma key effects in less than ideal lighting environments and provides keying of a перейти на источник into a virtual 3D environment through virtual set technology, and Adobe Stock Photos.

Below is a matrix of the applications that were bundled in each of the software suites for CS Following the release of CS5 in AprilAdobe changed its release strategy to an every other year release of major number installments. The update helped developers optimize websites for http://replace.me/19465.txt variety of tablets, smart phones, and other afvinity.

At the same time, Adobe announced a subscription-based pay service as an alternative to full purchase. Not all products were upgraded to CS5. Below is a c86 of affinity designer x86 free applications that were bundled in each of the software suites free CS5. On May 5,during the opening keynote of its Adobe MAX conference, Adobe announced that it was retiring the “Creative Suite” branding in favor of “Creative Cloud”, and making all future feature updates to its software frde appended with “CC” instead of “CS”, e.

Affinity designer x86 free CC available affinity designer x86 free the Creative Cloud subscription service rather designwr through the purchasing of perpetual licenses.

Customers must pay a subscription fee and if they stop paying, they will lose access to the proprietary file formats[39] [40] which are not backward-compatible with the Creative Suite [41] [42] Adobe admitted that this is a valid concern [43]. Individual subscribers must designerr an Internet connection [44] to download affinity designer x86 free software and to use the 2 GB of provided storage space or the additionally purchased eesigner GB [45]and must validate the license monthly.

Adobe’s decision to make the subscription service the only sales route for its creative software was met with strong criticism [47] [48] see Creative Cloud controversy. In addition to many of the products formerly part of the Creative Suite one product, Fireworks, affinity designer x86 free announced as having reached the end of its development cycle[56] Creative Cloud also offers subscription-exclusive products such as Designeer Muse [57] and the Adobe Edge family, [57] Web-based file affinity designer x86 free website hosting, Typekit fonts, and access to the Behance social media platform.

New versions with rree feature updates have been released regularly, with a refresh of the file formats occurring in October Adobe also announced that it would continue to offer bug fixes for the CS6 products so that they affinity designer x86 free continue to run on the next versions of Microsoft Windows and Apple OS X.

Software handles ignored bits in ACPI hardware registers the same way it handles reserved bits in these same types of registers. All versions of the ACPI tables must maintain backward compatibility. To accomplish this, modifications of the tables consist of redefinition of previously reserved fields and values plus appending data to the 1.

Modifications of the ACPI tables require that the version numbers of the modified tables be incremented. The length field in the tables includes all additions and the checksum is maintained for the entire length of the table.

Addresses used in the ACPI 1. This was targeted at the IA environment. Newer architectures require addressing mechanisms beyond that defined in ACPI 1. ACPI defines the fixed hardware low-level interfaces as a means to convey to the system OEM the minimum interfaces necessary to achieve a level of capability and quality for motherboard configuration and system power management.

Additionally, the definition of these interfaces, as well as others defined in this specification, conveys to OS Vendors OSVs developing ACPI-compatible operating systems, the necessary interfaces that operating systems must manipulate to provide robust support for system configuration and power management. While the definition of low-level hardware interfaces defined by ACPI 1. Unfortunately, the nature of SMM-based code makes this type of OS independent implementation difficult if not impossible to debug.

As such, this implementation approach is not recommended. In some cases, Functional Fixed Hardware implementations may require coordination with other OS components. As such, an OS independent implementation may not be viable. OS-specific implementations of functional fixed hardware can be implemented using technical information supplied by the CPU manufacturer. The downside of this approach is that functional fixed hardware support must be developed for each OS.

In some cases, the CPU manufacturer may provide a software component providing this support. In other cases support for the functional fixed hardware may be developed directly by the OS vendor. The hardware register definition was expanded, in ACPI 2. This is accomplished through the specification of an address space ID in the register definition see Generic Address Structure for more information.

When specifically directed by the CPU manufacturer, the system firmware may define an interface as functional fixed hardware by indicating 0x7F Functional Fixed Hardware , in the address space ID field for register definitions.

The size in bits of the given register. When addressing a data structure, this field must be zero. The bit offset of the given register at the given address. The bit address of the data structure or register in the given address space relative to the processor.

See below for specific formats. The bit physical memory address relative to the processor of the register. This can also be found as part of the DCE 1. This is the checksum of the fields defined in the ACPI 1. This includes only the first 20 bytes of this table, bytes 0 to 19, including the checksum field. These bytes must sum to zero. The revision of this structure. Larger revision numbers are backward compatible to lower revision numbers.

The ACPI version 1. It does not include the Length field and beyond. The current value for this field is 2. The length of the table, in bytes, including the header, starting from offset 0. This field is used to record the size of the entire table. This field is not available in the ACPI version 1. The Signature field in this table determines the content of the system description table. The revision of the structure corresponding to the signature field for this table. Larger revision numbers are backward compatible to lower revision numbers with the same signature.

This field is particularly useful when defining a definition block to distinguish definition block functions. Vendor ID of utility that created the table. Revision of utility that created the table.

The intent of these fields is to allow for a binary control system that support services can use. Because many support functions can be automated, it is useful when a tool can programmatically determine which table release is a compatible and more recent revision of a prior table on the same OEMID and OEM Table ID. Table 5. These system description tables may be defined by ACPI and documented within this specification, or they may simply be reserved by ACPI and defined by other industry specifications.

Based on the signature, OSPM can then interpret the implementation-specific data within the table. Length, in bytes, of the entire RSDT. The length implies the number of Entry fields n at the end of the table. Length, in bytes, of the entire table.

All fields in the FADT that provide hardware addresses provide processor-relative physical addresses. In this case, the bit field must be ignored regardless of whether or not it is zero, and whether or not it is the same value as the bit field.

The bit field should only be used if the corresponding bit field contains a zero value, or if the bit value can not be used by the OSPM subject to e. CPU addressing limitations. This signature predates ACPI 1. See Section 5. Physical memory address of the DSDT. ACPI 1. Platforms should set this field to zero but field values of one are also allowed to maintain compatibility with ACPI 1. System vector the SCI interrupt is wired to in mode.

On systems that do not contain the , this field contains the Global System interrupt number of the SCI interrupt. This field is reserved and must be zero on system that does not support System Management mode. This field is reserved and must be zero on systems that do not support Legacy Mode. The S4BIOS state provides an alternate way to enter the S4 state where the firmware saves and restores the memory context. See Section 4.

This is a required field. This field is optional; if this register block is not supported, this field contains zero. See Table 4. See the Section 4. This is an optional field; if this register block is not supported, this field contains zero. If this register block is not supported, this field contains zero. Support for the PM2 register block is optional. If not supported, this field contains zero.

The worst-case hardware latency, in microseconds, to enter and exit a C2 state. The worst-case hardware latency, in microseconds, to enter and exit a C3 state. This value is typically at least 2 times the cache size. This field is maintained for ACPI 1. If this field contains a zero, then the RTC day of the month alarm feature is not supported.

If this field contains a zero, then the RTC month of the year alarm feature is not supported. If this field contains a zero, then the RTC centenary feature is not supported. See Table 5. Fixed feature flags. Extended physical address of the FACS. Extended physical address of the DSDT. The address of the Sleep status register, represented in Generic Address Structure format see Section 4.

All bytes in this field are considered part of the vendor identity. These identifiers are defined independently by the vendors themselves, usually following the name of the hypervisor product.

Version information can be communicated through a supplemental vendor-specific hypervisor API. Firmware implementers would place zero bytes into this field, denoting that no hypervisor is present in the actual firmware. If set, signifies that the WBINVD instruction correctly flushes the processor caches, maintains memory coherency, and upon completion of the instruction, all caches for the current processor contain no cached data other than what OSPM references and allows to be cached.

If set, indicates that the hardware flushes all caches on the WBINVD instruction and maintains memory coherency, but does not guarantee the caches are invalidated. This provides the complete semantics of the WBINVD instruction, and provides enough to support the system sleeping states.

A zero indicates that the C2 power state is configured to only work on a uniprocessor UP system. A zero indicates the power button is handled as a fixed feature programming model; a one indicates the power button is handled as a control method device. Independent of the value of this field, the presence of a power button device in the namespace indicates to OSPM that the power button is handled as a control method device.

The RTC alarm can optionally support waking the system from the S4 state, as indicated by this value. A zero indicates that the system cannot support docking. A one indicates that the system can support docking. Notice that this flag does not indicate whether or not a docking station is currently present; it only indicates that the system is capable of docking. System Type Attribute.

If set indicates that the system has no internal expansion capabilities and the case is sealed. A value of one indicates that OSPM should use a platform provided timer to drive any monotonically non-decreasing counters, such as OSPM performance counter services. A value of one indicates that the platform is known to have a correctly implemented ACPI power management timer. A platform may choose to set this flag if a internal processor clock or clocks in a multi-processor configuration cannot provide consistent monotonically non-decreasing counters.

Note: If a value of zero is present, OSPM may arbitrarily choose to use an internal processor clock or a platform timer clock for these operations. That is, a zero does not imply that OSPM will necessarily use the internal processor clock to generate a monotonically non-decreasing counter to the system. Some existing systems do not reliably set this input today, and this bit allows OSPM to differentiate correctly functioning platforms from platforms with this errata.

A one indicates that the platform is compatible with remote power- on. Some existing platforms do not reliably transition to S5 with wake events enabled for example, the platform may immediately generate a spurious wake event after completing the S5 transition. This flag allows OSPM to differentiate correctly functioning platforms from platforms with this type of errata.

A one indicates that all local APICs must be configured for the cluster destination model when delivering interrupts in logical mode. A one indicates that all local xAPICs must be configured for physical destination mode.

If this bit is set, interrupt delivery operation in logical destination mode is undefined. A one informs OSPM that the platform is able to achieve power savings in S0 similar to or better than those typically achieved in S3.

In effect, when this bit is set it indicates that the system will achieve no power benefit by making a sleep transition to S3.

Most often contains one processor. Must be connected to AC power to function. This device is used to perform work that is considered mainstream corporate or home computing for example, word processing, Internet browsing, spreadsheets, and so on.

A single-user, full-featured, portable computing device that is capable of running on batteries or other power storage devices to perform its normal functions. This device performs the same task set as a desktop. Often contains more than one processor. A multi-user, stationary computing device that frequently resides in a separate, often specially designed, room. Will almost always contain more than one processor.

This device is used to support large-scale networking, database, communications, or financial operations within a corporation or government. A multi-user, stationary computing device that frequently resides in a separate area or room in a small or home office.

May contain more than one processor. This device is generally used to support all of the networking, database, communications, and financial operations of a small office or home office. A multi-user stationary computing device that frequently resides in a separate, often specially designed room. Will often contain more than one processor. This device is used in an environment where power savings features are willing to be sacrificed for better performance and quicker responsiveness.

A full-featured, highly mobile computing device which resembles writing tablets and which users interact with primarily through a touch interface.

Tablet devices typically run on battery power and are generally only plugged into AC power in order to charge. This device performs many of the same tasks as Mobile; however battery life expectations of Tablet devices generally require more aggressive power savings especially for managing display and touch components.

This set of flags is used by the OS to assist in determining assumptions about power and device management. These flags are read at boot time and are used to make decisions about power management and device settings. These flags are used by an OS at boot time before the OS is capable of providing an operating environment suitable for parsing the ACPI namespace to determine the code paths to take during boot. For example, if there are no ISA devices, an OS could skip code that assumes the presence of these devices and their associated resources.

These flags are used independently of the ACPI namespace. On other system architectures, the entire field should be set to 0. User-visible devices are devices that have end-user accessible connectors for example, LPT port , or devices for which the OS must load a device driver so that an end-user application can use a device. If clear, the OS may assume there are no such devices and that all devices in the system can be detected exclusively via industry standard device enumeration mechanisms including the ACPI namespace.

If set, indicates that the motherboard contains support for a port 60 and 64 based keyboard controller, usually implemented as an or equivalent micro-controller. For example, the E address map reporting interface would report the region as AddressRangeReserved. For more information, see Section This value is 64 bytes or larger. This value is calculated by the platform boot firmware on a best effort basis to indicate the base hardware configuration of the system such that different base hardware configurations can have different hardware signature values.

If the values are not the same, OSPM assumes that the saved non-volatile image is from a different hardware configuration and cannot be restored. The bit address field where OSPM puts its waking vector. Before transitioning the system into a global sleeping state, OSPM fills in this field with the physical memory address of an OS-specific wake function.

On PCs, the wake function address is in memory below 1 MB and the control is transferred while in real mode. If, for example, the physical address is 0x, then the BIOS must jump to real mode address 0xx This field contains the Global Lock used to synchronize access to shared hardware resources between the OSPM environment and an external controller environment for example, the SMI environment.

This lock is owned exclusively by either OSPM or the firmware at any one time. When ownership of the lock is attempted, it might be busy, in which case the requesting environment exits and waits for the signal that the lock has been released. For example, the Global Lock can be used to protect an embedded controller interface such that only OSPM or the firmware will access the embedded controller interface at any one time.

Memory address translation must be disabled The processor must have psr. For IA 32 and x64 platforms, platform firmware is required to support a 32 bit execution environment. Platform firmware can additionally support a 64 bit execution environment.

Otherwise, the platform firmware creates a 32 bit execution environment. IF set to 0 Long mode enabled Paging mode is enabled and physical memory for waking vector is identity mapped virtual address equals physical address Waking vector must be contained within one physical page Selectors are set to be flat and are otherwise not used For 32 bit execution environment: Interrupts must be disabled EFLAGS.

Note: this is not a pointer to the Global Lock, it is the actual memory location of the lock. By convention, this lock is used to ensure that while one environment is accessing some hardware, the other environment is not. When releasing the lock, if the pending bit in the lock is set after the lock is released, a signal is sent via an interrupt mechanism to the other environment to inform it that the lock has been released.

If non-zero is returned by the function, the caller has been granted ownership of the Global Lock and can proceed. If non-zero is returned, the caller must raise the appropriate event to the other environment to signal that the Global Lock is now free. This signal only occurs when the other environment attempted to acquire ownership while the lock was owned. Although using the Global Lock allows various hardware resources to be shared, it is important to notice that its usage when there is ownership contention could entail a significant amount of system overhead as well as waits of an indeterminate amount of time to acquire ownership of the Global Lock.

Similarly if the entire register is shared, as the case might be for the embedded controller interface, access to the register needs to be protected under the Global Lock. The top-level organization of this information after a definition block is loaded is name-tagged in a hierarchical namespace. As mentioned, the AML Load and LoadTable operators make it possible for a Definition Block to load other Definition Blocks, either statically or dynamically, where they in turn can either define new system attributes or, in some cases, build on prior definitions.

Although this gives the hardware the ability to vary widely in implementation, it also confines it to reasonable boundaries. In some cases, the Definition Block format can describe only specific and well-understood variances. Some AML operators perform simple functions, and others encompass complex functions. The power of the Definition block comes from its ability to allow these operations to be glued together in numerous ways, to provide functionality to OSPM.

The AML operators defined in this specification are intended to allow many useful hardware designs to be easily expressed, not to allow all hardware designs to be expressed. Existing ACPI definition block implementations may contain an inherent assumption of a bit integer width. Therefore, to maintain backwards compatibility, OSPM uses the Revision field, in the header portion of system description tables containing Definition Blocks, to determine whether integers declared within the Definition Block are to be evaluated as bit or bit values.

Values less than two will cause the interpreter to use bit integers and math. Values of two and greater will cause the interpreter to use full bit integers and math. There can be multiple SSDTs present.

This allows the OEM to provide the base support in one table and add smaller system options in other tables. For example, the OEM might put dynamic object definitions into a secondary table such that the firmware can construct the dynamic information at boot without needing to edit the static DSDT.

The ACPI interrupt model describes all interrupts for the entire system in a uniform interrupt model implementation. The choice of the interrupt model s to support is up to the platform designer.

The interrupt model cannot be dynamically changed by the system firmware; OSPM will choose which model to use and install support for that model at the time of installation. If a platform supports multiple models, an OS will install support for only one of the models; it will not mix models. Multi-boot capability is a feature in many modern operating systems.

This means that a system may have multiple operating systems or multiple instances of an OS installed at any one time. Platform designers must allow for this. Only legacy systems should continue with this usage. A list of interrupt controller structures for this implementation. This list will contain all of the structures from Interrupt Controller Structure Types needed to support this platform.

These structures are described in the following sections. A one indicates that the system also has a PC-AT-compatible dual setup. Immediately after the Flags value in the MADT is a list of interrupt controller structures that declare the interrupt features of the machine. The first byte of each structure declares the type of that structure and the second byte declares the length of that structure. OSPM implementations may limit the number of supported processors on multi-processor platforms.

OSPM executes on the boot processor to initialize the platform including other processors. To ensure that the boot processor is supported post initialization, two guidelines should be followed.

The second is that platform firmware should list the boot processor as the first processor entry in the MADT. The advent of multi-threaded processors yielded multiple logical processors executing on common processor hardware. ACPI defines logical processors in an identical manner as physical processors. To ensure that non multi-threading aware OSPM implementations realize optimal performance on platforms containing multi-threaded processors, two guidelines should be followed.

The second is that platform firmware should list the first logical processor of each of the individual multi-threaded processors in the MADT before listing any of the second logical processors. This approach should be used for all successive logical processors. Failure of OSPM implementations and platform firmware to abide by these guidelines can result in both unpredictable and non optimal platform operation.

OSPM does not expect the information provided in this table to be updated if the processor information changes during the lifespan of an OS boot. Note that the use of the Processor declaration operator is deprecated. See the description at the beginning of this section for more information. Local APIC flags. See the following table Table 5. If this bit is set the processor is ready for use.

If this bit is clear and the Online Capable bit is set, system hardware supports enabling this processor during OS runtime. The information conveyed by this bit depends on the value of the Enabled bit. If the Enabled bit is set, this bit is reserved and must be zero. Otherwise, if this this bit is set, system hardware supports enabling this processor during OS runtime. For more information on global system interrupts see Section 5. When OSPM supports the model, it will assume that all interrupt descriptors reporting global system interrupts correspond to IRQs.

The Interrupt Source Override Structure is provided in order to describe these exceptions. Only those that are not identity-mapped onto the APIC interrupt inputs need be described.

Interrupt Source Overrides are also necessary when an identity mapped interrupt input has a non-standard polarity. Any source that is non-maskable will not be available for use by devices. A value of 0xFF signifies that this applies to all processors in the machine. The Global System Interrupt Base field remains unchanged but has been moved. A new address and reserved field have been added. The use of the Processor statement is deprecated. If a platform can generate an interrupt after correcting platform errors e.

Some systems may restrict the retrieval of corrected platform error information to a specific processor. In such cases, the firmware indicates the processor that can retrieve the corrected platform error information through the Processor ID and EID fields in the structure below.

On platforms where the retrieval of corrected platform error information can be performed on any processor, the firmware indicates this capability by setting the CPEI Processor Override flag in the Platform Interrupt Source Flags field of the structure below. It is allowed for such an entry to refer to a Global System Interrupt that is already specified by a Platform Interrupt Source Structure provided through the static MADT table, provided the value of platform interrupt source flags are identical.

Platform Interrupt Source Flags. See Platform Interrupt Source Flags for a description of this field. When a logical processor is not present, the processor local X2APIC information is either not reported or flagged as disabled. If it is not supported by the implementation, then this field must be zero. If the platform is not presenting a GICv2 with virtualization extensions this field can be 0.

Address of the GIC virtual interface control block registers. On systems supporting GICv3 and above, this field holds the bit physical address of the associated Redistributor. If all of the GIC Redistributors are in the always-on power domain, GICR structures should be used to describe the Redistributors instead, and this field must be set to 0.

Describes the relative power efficiency of the associated processor. Lower efficiency class numbers are more efficient than higher ones e.

This interrupt is a level triggered PPI. Zero if SPE is not supported by this processor. If zero, this processor is unusable, and the operating system support will not attempt to use it. The frame also includes registers to discover the set of distributor lines which may be signaled by MSIs from that frame.

A system may have multiple MSI frames, and separate frames may be defined for secure and non-secure access. This structure must only be used to describe non-secure MSI frames.

SPI Count used by this frame. SPI Base used by this frame. GICR structures should only be used when describing GIC implementations which conform to version 3 or higher of the GIC architecture and which place all Redistributors in the always-on power domain. The platform firmware publishes a multiprocessor wakeup structure to let the bootstrap processor wake up application processors with a mailbox. The mailbox is memory that the firmware reserves so that each processor can have the OS send a message to them.

During system boot, the firmware puts the application processors in a state to check the mailbox. The firmware is not allowed to modify the mailbox location when the firmware transfer the control to an OS loader. The mailbox is broken down into two 2KB sections: an OS section and a firmware section.

The OS section can only be written by OS and read by the firmware, except the command field. The application processor need clear the command to Noop 0 as the acknowledgement that the command is received. The firmware must cache the content in the mailbox which might be used later before clear the command such as WakeupVector. Only after the command is changed to Noop 0 , the OS can send the next command. The firmware section must be considered read-only to the OS and is only to be written to by the firmware.

All data communication between the OS and FW must be in little endian format. For each application processor, the mailbox can be used only once for the wakeup command. After the application process takes the action according to the command, this mailbox will no longer be checked by this application processor. Other processors can continue using the mailbox for the next command. Physical address of the mailbox. It must also be 4K bytes aligned. They are used to virtualize interrupts in tables and in ASL methods that perform resource allocation of interrupts.

There are two interrupt models used in ACPI-enabled systems. The first model is the APIC model. This mapping is depicted in the following figure.

If the platform supports batteries as defined by the Smart Battery Specification 1. This table indicates the energy level trip points that the platform requires for placing the system into the specified sleeping state and the suggested energy levels for warning the user to transition the platform into a sleeping state. OSPM uses these tables with the capabilities of the batteries to determine the different trip points.

In such cases, the firmware indicates the processor that can retrieve the corrected platform error information through the Processor ID and EID fields in the structure below. On platforms where the retrieval of corrected platform error information can be performed on any processor, the firmware indicates this capability by setting the CPEI Processor Override flag in the Platform Interrupt Source Flags field of the structure below.

On systems supporting GICv3 and above, this field holds the bit physical address of the associated Redistributor. If all of the GIC Redistributors are in the always-on power domain, GICR structures should be used to describe the Redistributors instead, and this field must be set to 0. Describes the relative power efficiency of the associated processor.

Physical address of the mailbox. It must also be 4K bytes aligned. They are used to virtualize interrupts in tables and in ASL methods that perform resource allocation of interrupts. There are two interrupt models used in ACPI-enabled systems.

The first model is the APIC model. This mapping is depicted in the following figure. If the platform supports batteries as defined by the Smart Battery Specification 1. This table indicates the energy level trip points that the platform requires for placing the system into the specified sleeping state and the suggested energy levels for warning the user to transition the platform into a sleeping state.

OSPM uses these tables with the capabilities of the batteries to determine the different trip points. For more precise definitions of these levels, see Section 3. This optional table provides the processor-relative, translated resources of an Embedded Controller. The presence of this table allows OSPM to provide Embedded Controller operation region space access before the namespace has been evaluated. If this table is not provided, the Embedded Controller region space will not be available until the Embedded Controller device in the AML namespace has been discovered and enumerated.

Contains the processor-relative address, represented in Generic Address Structure format, of the Embedded Controller Data register. Quotes are omitted in the data field. See Section 6. Length, in bytes, of the entire SRAT. The length implies the number of Entry fields at the end of the table. A list of static resource allocation structures for the platform.

This allows system firmware to populate the SRAT with a static number of structures but only enable them as necessary. The Memory Affinity structure provides the following topology information statically to the operating system:.

The system hardware supports hot-add and hot-remove of this memory region If the Enabled bit is set and the Hot Pluggable bit is clear, the system hardware does not support hot-add or hot-remove of this memory region. See the corresponding table below for a description of this field.

This enables the OSPM to discover the memory that is closest to the ITS, and use that in allocating its management tables and command queue. The Generic Initiator Affinity Structure provides the association between a generic initiator and the proximity domain to which the initiator belongs.

If a generic device with coherent memory is attached to the system, it is recommended to define affinity structures for both the device and memory associated with the device.

One example is lack of cache coherency support on the GI, if the GI does not have any local caches to global memory that require invalidation through the data fabric. OS is assured that the GI adheres to the memory model as the host processor architecture related to observable transactions to memory for memory fences and other synchronization operations issued on either initiator or host.

This provides the capability to describe the scenario where the relative distances for the two directions between System Localities is different. The diagonal elements of the matrix, the relative distances from a System Locality to itself are normalized to a value of The relative distances for the non-diagonal elements are scaled to be relative to For example, if the relative distance from System Locality i to System Locality j is 2. If one locality is unreachable from another, a value of 0xFF is stored in that table entry.

Distance values of are reserved and have no meaning. Platforms may contain the ability to detect and correct certain operational errors while maintaining platform function. These errors may be logged by the platform for the purpose of retrieval. Depending on the underlying hardware support, the means for retrieving corrected platform error information varies. Alternatively, OSPM may poll processors for corrected platform error information.

Error log information retrieved from a processor may contain information for all processors within an error reporting group. As such, it may not be necessary for OSPM to poll all processors in the system to retrieve complete error information. Length, in bytes, of the entire CPET. See corresponding table below. See corresponding table below for details of the Corrected Platform Error Polling Processor structure.

If the system maximum topology is not known up front at boot time, then this table is not present. Indicates the maximum number of Proximity Domains ever possible in the system. The number reported in this field is maximum domains – 1. For example if there are 0x possible domains in the system, this field would report 0xFFFF.

Indicates the maximum number of Clock Domains ever possible in the system. Indicates the maximum Physical Address ever possible in the system. Note: this is the top of the reachable physical address.

A list of Proximity Domain Information for this implementation. It is likely that these characteristics may be the same for many proximity domains, but they can vary from one proximity domain to another. This structure optimizes to cover the former case, while allowing the flexibility for the latter as well. These structures must be organized in ascending order of the proximity domain enumerations.

The starting proximity domain for the proximity domain range that this structure is providing information. The ending proximity domain for the proximity domain range that this structure is providing information. A value of 0 means that the proximity domains do not contain processors. A value of 0 means that the proximity domains do not contain memory. Length in bytes for entire RASF. The Platform populates this field. The Bit Map is described in Section 5.

These parameter blocks are used as communication mailbox between the OSPM and the platform, and there is 1 parameter block for each RAS feature. NOTE: There can be only on parameter block per type. Indicates that the platform supports hardware based patrol scrub of DRAM memory and platform exposes this capability to software using this RASF mechanism.

The following table describes the Parameter Blocks. The structure is used to pass parameters for controlling the corresponding RAS Feature. The platform calculates the nearest patrol scrub boundary address from where it can start. This range should be a superset of the Requested Address Range. The following sequence documents the steps for OSPM to identify whether the platform supports hardware based patrol scrub and invoke commands to request hardware to patrol scrub the specified address range.

Identify whether the platform supports hardware based patrol scrub and exposes the support to software by reading the RAS capabilities bitmap in the RASF table.

This table defines the memory power node topology of the configuration, as described earlier in Section 1. The configuration includes specifying memory power nodes and their associated information. Each memory power node is specified using address ranges, supported memory power states. The memory power states will include both hardware controlled and software controlled memory power states. There can be multiple entries for a given memory power node to support non contiguous address ranges.

MPST table also defines the communication mechanism between OSPM and platform runtime firmware for triggering software controlled memory powerstate transitions implemented in platform runtime firmware. Length in bytes for entire MPST. This field provides information on the memory power nodes present in the system. Further details of this field are specified in Memory Power Node. This field provides information of memory power states supported in the system.

The information includes power consumed, transition latencies, relevant flags. See the table below. All other command values are reserved. The PCC signature. The signature of a subspace is computed by a bitwise-or of the value 0x with the subspace ID.

OSPM should use the ratio of computed memory power consumed to expected average power consumed in determining the memory power management action. Memory Power State represents the state of a memory power node which maps to a memory address range while the platform is in the G0 working state. It should be noted that active memory power state MPS0 does not preclude memory power management in that state. It only indicates that any active state memory power management in MPS0 is transparent to the OSPM and more importantly does not require assist from OSPM in terms of restricting memory occupancy and activity.

In all three cases, these states require explicit OSPM action to isolate and free the memory address range for the corresponding memory power node. Power state transition diagram is shown in Fig. If platform is capable of returning to a memory power state on subsequent period of idle, the platform must treat the previously requested memory power state as a persistent hint.

This state value maps to active state of memory node Normal operation. OSPM can access memory during this state. This state value can be mapped to any memory power state depending on the platform capability.

By convention, it is required that low value power state will have lower power savings and lower latencies than the higher valued power states. SetMemoryPowerState : The following sequence needs to be done to set a memory power state. GetMemoryPowerState : The following sequence needs to be done to get the current memory power state. Memory Power Node is a representation of a logical memory region that needs to be transitioned in and out of a memory power state as a unit.

This logical memory region is made up of one more system memory address range s. Note that memory power node structure defined in Table 5. This address range should be 4K aligned. If a Memory Power Node contains more than one memory address range i.

Memory Power Nodes are not hierarchical. OSPM is expected to identify the memory power node s that corresponds to the maximum memory address range that OSPM is able to power manage at a given time. The following structure specifies the fields used for communicating memory power node information. Each entry in the MPST table will be having corresponding memory power node structure defined. This structure communicates address range, number of power states implemented, information about individual power states, number of distinct physical components that comprise this memory power node.

The physical component identifiers can be cross-referenced against the memory topology table entries. The flag describes type of memory node. See the Table 5. This field provides memory power node number. Length in bytes for Memory Power Node Structure. Low 32 bits of Length of the memory range.

This field indicates number of power states supported for this memory power node and in turn determines the number of entries in memory power state structure. This field indicates the number of distinct Physical Components that constitute this memory power node. This field is also used to identify the number of entries of Physical Component Identifier entries present at end of this table.

This field provides information of various power states supported in the system for a given memory power node.

This allows system firmware to populate the MPST with a static number of structures but enable them as necessary. This flag indicates that the memory node supports the hot plug feature.

See Interaction with Memory Hot Plug. This field provides value of power state. The specific value to be used is system dependent. However convention needs to be maintained where higher numbers indicates deeper power states with higher power savings and higher latencies. For example, a power state value of 2 will have higher power savings and higher latencies than a power state value of 1.

This field provides unique index into the memory power state characteristics entries which will provide details about the power consumed, power state characteristics and transition latencies. The indexing mechanism is to avoid duplication and hence reduce potential for mismatch errors of memory power state characteristics entries across multiple memory nodes.

The table below describes the power consumed, exit latency and the characteristics of the memory power state. This table is referenced by a memory power node. The flag describes the caveats associated with entering the specified power state. Refer to Table 5. This field provides average power consumed for this memory power node in MPS0 state. This power is measured in milliWatts and signifies the total power consumed by this memory the given power state as measured in DC watts.

Note that this value should be used as guideline only for estimating power savings and not as actual power consumed.

If Bit [1] is set, this field indicates that given memory power state entry transition needs to be triggered explicitly by OSPM by calling the Set Power State command. If Bit [1] is clear, this field indicates that given memory power state entry transition is automatically implemented in hardware and does not require a OSPM trigger. The role of OSPM in this case is to ensure that the corresponding memory region is idled from a software standpoint to facilitate entry to the state.

System behavior is undefined if OSPM or other software agents attempt to access memory that is currently in a low power state. If Bit [1] is clear, this field indicates that given memory power state is exited automatically on access to the memory address range corresponding to the memory power node. Exit Latency provided in the Memory Power Characteristics structure for a specific power state is inclusive of the entry latency for that state.

In such fully autonomous states, the decision to enter the state is made by hardware based on the utilization of the corresponding memory region and the decision to exit the memory power state is initiated in response to a memory access targeted to the corresponding memory region. The role of OSPM software in handling such autonomous memory power states is to vacate the use of such memory regions when possible in order to allow hardware to effectively save power.

No other OSPM initiated action is required for supporting these autonomously power managed regions. However, it is not an error for OSPM explicitly initiates a state transition to an autonomous entry memory power state through the MPST command interface. The platform may accept the command and enter the state immediately in which case it must return command completion with SUCCESS b status. Platform firmware may have regions of memory reserved for its own use that are unavailable to OSPM for allocation.

Memory nodes where all or a portion of the memory is reserved by platform firmware may pose a problem for OSPM because it does not know whether the platform firmware reserved memory is in use. If the platform firmware reserved memory impacts the ability of the memory power node to enter memory power state s , the platform must indicate to OSPM by clearing the Power Managed Flag – see Table 5. This allows OSPM to ignore such ranges from its memory power optimization.

The memory power state table describes address range for each of the memory power nodes specified. An example of policy which can be implemented in OSPM for memory coalescing is: OSPM can prefer allocating memory from local memory power nodes before going to remote memory power nodes. The later sections provide sample NUMA configurations and explain the policy for various memory power nodes. The hot pluggable memory regions are described using memory device objects see Section 9. The memory power state table MPST is a static structure created for all memory objects independent of hot plug status online or offline during initialization.

For example, such memory is not cacheline interleaved. Reference to memory in this document always refers to host physical memory.

For virtualized environments, this requires hypervisors to be responsible for memory power management. Hypervisors also have the ability to create opportunities for memory power management by vacating appropriate host physical memory through remapping guest physical memory.

DIMMs associated with a parent memory device. The number of top level Memory Device structures that immediately follow. A zero in this field indicates no Memory Device structures follow. A list of memory device structures for the platform. Length in bytes for this structure.

It is not expected that OSPM will utilize this field. The Boot Graphics Resource Table BGRT is an optional table that provides a mechanism to indicate that an image was drawn on the screen during boot, and some information about the image. The table is written when the image is drawn on the screen. This should be done after it is expected that any firmware components that may write to the screen are done doing so and it is known that the image is the only thing on the screen.

Adobe sold Creative Suite applications in several different combinations called “editions”, these included:. Adobe Prelude and Adobe Encore are not released as standalone products. Adobe Encore is available as part of Adobe Premiere Pro.

In March , it was reported that Adobe would no longer sell boxed copies of the Creative Suite software, instead offering digital downloads and monthly subscriptions. Creative Suite helped InDesign become the dominant publishing software, replacing QuarkXPress , because customers who purchased the suite for Photoshop and Illustrator received InDesign at no additional cost.

Adobe shut down the “activation” servers for CS2 in December , making it impossible for licensed users to reinstall the software if needed. In response to complaints, Adobe then made available for download a version of CS2 that did not require online activation, and published a serial number to activate it offline. Adobe Creative Suite Production Studio previously Adobe Video Collection was a suite of programs for acquiring, editing, and distributing digital video and audio that was released during the same timeframe as Adobe Creative Suite 2.

The suite was available in standard and premium editions. Macromedia Studio was a suite of programs designed for web content creation designed and distributed by Macromedia.

After Adobe ‘s acquisition of Macromedia, Macromedia Studio 8 was replaced, modified, and integrated into two editions of the Adobe Creative Suite family of software from version 2. Some Macromedia applications were absorbed into existing Adobe products, e.

FreeHand has been replaced with Adobe Illustrator. Director and ColdFusion are not part of Adobe Creative Suite and will only be available as standalone products. The final version of Macromedia Studio released include:. Adobe Creative Suite 3 CS3 was announced on March 27, ; it introduced universal binaries for all major programs for the Apple Macintosh , [19] as well as including all of the core applications from Macromedia Studio and Production Studio. Some Creative Suite programs also began using the Presto layout engine used in the Opera web browser.

Adobe began selling CS3 applications in six different combinations called “editions. The latest released CS3 version was version 3. CS3 included several programs, including Dreamweaver , Flash Professional , and Fireworks that were developed by Macromedia , a former rival acquired by Adobe in Adobe dropped the following programs that were previously included in CS2 from the CS3 software bundles: [22].

Adobe had announced that it would continue to develop Audition as a standalone product, while GoLive had been discontinued. Adobe GoLive 9 was released as a standalone product on June 10, Adobe Audition 3 was announced as a standalone product on September 6, Adobe had discontinued ImageReady and had replaced it with Fireworks, with some of ImageReady’s features integrated into Photoshop. Audition became part of the Creative Suite again in CS5. Adobe CS4 was also developed to perform better under bit and multi-core processors.

Two programs were dropped from the CS4 line-up: Adobe Ultra , a vector keying application which utilizes image analysis technology to produce high quality chroma key effects in less than ideal lighting environments and provides keying of a subject into a virtual 3D environment through virtual set technology, and Adobe Stock Photos.

Ему было не привыкать работать допоздна даже по уикэндам; именно эти сравнительно спокойные часы в АНБ, как правило, были единственным временем, когда он мог заниматься обслуживанием компьютерной техники. Просунув раскаленный паяльник сквозь проволочный лабиринт у себя над головой, он действовал с величайшей осмотрительностью: опалить защитную оболочку провода значило вывести аппарат из строя. Еще несколько сантиметров, подумал Джабба.

See Section 5. Physical memory address of the DSDT. ACPI 1. Platforms should set this field to zero but field values of one are also allowed to maintain compatibility with ACPI 1. System vector the SCI interrupt is wired to in mode. On systems that do not contain the , this field contains the Global System interrupt number of the SCI interrupt. This field is reserved and must be zero on system that does not support System Management mode.

This field is reserved and must be zero on systems that do not support Legacy Mode. The S4BIOS state provides an alternate way to enter the S4 state where the firmware saves and restores the memory context. See Section 4. This is a required field. This field is optional; if this register block is not supported, this field contains zero. See Table 4.

See the Section 4. This is an optional field; if this register block is not supported, this field contains zero.

If this register block is not supported, this field contains zero. Support for the PM2 register block is optional. If not supported, this field contains zero. The worst-case hardware latency, in microseconds, to enter and exit a C2 state. The worst-case hardware latency, in microseconds, to enter and exit a C3 state. This value is typically at least 2 times the cache size. This field is maintained for ACPI 1. If this field contains a zero, then the RTC day of the month alarm feature is not supported.

These identifiers are defined independently by the vendors themselves, usually following the name of the hypervisor product. Version information can be communicated through a supplemental vendor-specific hypervisor API. Firmware implementers would place zero bytes into this field, denoting that no hypervisor is present in the actual firmware. If set, signifies that the WBINVD instruction correctly flushes the processor caches, maintains memory coherency, and upon completion of the instruction, all caches for the current processor contain no cached data other than what OSPM references and allows to be cached.

Independent of the value of this field, the presence of a power button device in the namespace indicates to OSPM that the power button is handled as a control method device.

A zero indicates the RTC wake status is supported in fixed register space; a one indicates the RTC wake status is not supported in fixed register space. Indicates whether the RTC alarm function can wake the system from the S4 state. The RTC alarm can optionally support waking the system from the S4 state, as indicated by this value. A zero indicates that the system cannot support docking.

A one indicates that the system can support docking. Notice that this flag does not indicate whether or not a docking station is currently present; it only indicates that the system is capable of docking. System Type Attribute. If set indicates that the system has no internal expansion capabilities and the case is sealed.

A platform may choose to set this flag if a internal processor clock or clocks in a multi-processor configuration cannot provide consistent monotonically non-decreasing counters.

Some existing systems do not reliably set this input today, and this bit allows OSPM to differentiate correctly functioning platforms from platforms with this errata. A one indicates that the platform is compatible with remote power- on. Some existing platforms do not reliably transition to S5 with wake events enabled for example, the platform may immediately generate a spurious wake event after completing the S5 transition. This flag allows OSPM to differentiate correctly functioning platforms from platforms with this type of errata.

In effect, when this bit is set it indicates that the system will achieve no power benefit by making a sleep transition to S3. Most often contains one processor. Must be connected to AC power to function. This device is used to perform work that is considered mainstream corporate or home computing for example, word processing, Internet browsing, spreadsheets, and so on.

Will almost always contain more than one processor. This device is used to support large-scale networking, database, communications, or financial operations within a corporation or government.

Will often contain more than one processor. This device is used in an environment where power savings features are willing to be sacrificed for better performance and quicker responsiveness.

A full-featured, highly mobile computing device which resembles writing tablets and which users interact with primarily through a touch interface. Tablet devices typically run on battery power and are generally only plugged into AC power in order to charge. This device performs many of the same tasks as Mobile; however battery life expectations of Tablet devices generally require more aggressive power savings especially for managing display and touch components.

For example, if there are no ISA devices, an OS could skip code that assumes the presence of these devices and their associated resources. These flags are used independently of the ACPI namespace. On other system architectures, the entire field should be set to 0. User-visible devices are devices that have end-user accessible connectors for example, LPT port , or devices for which the OS must load a device driver so that an end-user application can use a device.

If clear, the OS may assume there are no such devices and that all devices in the system can be detected exclusively via industry standard device enumeration mechanisms including the ACPI namespace. If set, indicates that the motherboard contains support for a port 60 and 64 based keyboard controller, usually implemented as an or equivalent micro-controller.

For example, the E address map reporting interface would report the region as AddressRangeReserved. For more information, see Section This value is 64 bytes or larger. This value is calculated by the platform boot firmware on a best effort basis to indicate the base hardware configuration of the system such that different base hardware configurations can have different hardware signature values.

Any change to the data in Persistent Memory itself should not be included in computing the hardware signature. OSPM uses this information in waking from an S4 state, by comparing the current hardware signature to the signature values saved in the non-volatile sleep image. If the values are not the same, OSPM assumes that the saved non-volatile image is from a different hardware configuration and cannot be restored.

The bit address field where OSPM puts its waking vector. Before transitioning the system into a global sleeping state, OSPM fills in this field with the physical memory address of an OS-specific wake function. On PCs, the wake function address is in memory below 1 MB and the control is transferred while in real mode. If, for example, the physical address is 0x, then the BIOS must jump to real mode address 0xx This field contains the Global Lock used to synchronize access to shared hardware resources between the OSPM environment and an external controller environment for example, the SMI environment.

IF set to 0 Long mode enabled Paging mode is enabled and physical memory for waking vector is identity mapped virtual address equals physical address Waking vector must be contained within one physical page Selectors are set to be flat and are otherwise not used For 32 bit execution environment: Interrupts must be disabled EFLAGS. OSPM enabled firmware control structure flags. Platform firmware must initialize this field to zero. Indicates that the platform firmware supports a 64 bit execution environment for the waking vector.

For this reason, implementations should try to design the hardware to keep the required usage of the Global Lock to a minimum. The Global Lock is required whenever a logical register in the hardware is shared. Similarly if the entire register is shared, as the case might be for the embedded controller interface, access to the register needs to be protected under the Global Lock.

The top-level organization of this information after a definition block is loaded is name-tagged in a hierarchical namespace. As mentioned, the AML Load and LoadTable operators make it possible for a Definition Block to load other Definition Blocks, either statically or dynamically, where they in turn can either define new system attributes or, in some cases, build on prior definitions.

Therefore, to maintain backwards compatibility, OSPM uses the Revision field, in the header portion of system description tables containing Definition Blocks, to determine whether integers declared within the Definition Block are to be evaluated as bit or bit values. A Revision field value greater than or equal to 2 signifies that integers declared within the Definition Block are to be evaluated as bit values.

See Section This field also sets the global integer width for the AML interpreter. Values less than two will cause the interpreter to use bit integers and math. Values of two and greater will cause the interpreter to use full bit integers and math. There can be multiple SSDTs present. This allows the OEM to provide the base support in one table and add smaller system options in other tables. For example, the OEM might put dynamic object definitions into a secondary table such that the firmware can construct the dynamic information at boot without needing to edit the static DSDT.

If a platform supports multiple models, an OS will install support for only one of the models; it will not mix models. Multi-boot capability is a feature in many modern operating systems. This means that a system may have multiple operating systems or multiple instances of an OS installed at any one time.

To ensure that the boot processor is supported post initialization, two guidelines should be followed. The second is that platform firmware should list the boot processor as the first processor entry in the MADT. The advent of multi-threaded processors yielded multiple logical processors executing on common processor hardware. ACPI defines logical processors in an identical manner as physical processors. To ensure that non multi-threading aware OSPM implementations realize optimal performance on platforms containing multi-threaded processors, two guidelines should be followed.

Failure of OSPM implementations and platform firmware to abide by these guidelines can result in both unpredictable and non optimal platform operation. OSPM does not expect the information provided in this table to be updated if the processor information changes during the lifespan of an OS boot.

Note that the use of the Processor declaration operator is deprecated. See the description at the beginning of this section for more information.

Local APIC flags. See the following table Table 5. If this bit is set the processor is ready for use. If this bit is clear and the Online Capable bit is set, system hardware supports enabling this processor during OS runtime.

The information conveyed by this bit depends on the value of the Enabled bit. If the Enabled bit is set, this bit is reserved and must be zero. Otherwise, if this this bit is set, system hardware supports enabling this processor during OS runtime. For more information on global system interrupts see Section 5. When OSPM supports the model, it will assume that all interrupt descriptors reporting global system interrupts correspond to IRQs.

In the model all global system interrupts greater than 15 are ignored. For more information on hardware resource configuration see Section 6. Most existing APIC designs, however, will contain at least one exception to this assumption. The Interrupt Source Override Structure is provided in order to describe these exceptions. Only those that are not identity-mapped onto the APIC interrupt inputs need be described. Interrupt Source Overrides are also necessary when an identity mapped interrupt input has a non-standard polarity.

Any source that is non-maskable will not be available for use by devices. A value of 0xFF signifies that this applies to all processors in the machine. The Global System Interrupt Base field remains unchanged but has been moved. A new address and reserved field have been added. The use of the Processor statement is deprecated. If a platform can generate an interrupt after correcting platform errors e.

See Platform Interrupt Source Flags for a description of this field. When a logical processor is not present, the processor local X2APIC information is either not reported or flagged as disabled.

If it is not supported by the implementation, then this field must be zero. If the platform is not presenting a GICv2 with virtualization extensions this field can be 0. Address of the GIC virtual interface control block registers. On systems supporting GICv3 and above, this field holds the bit physical address of the associated Redistributor.

The frame also includes registers to discover the set of distributor lines which may be signaled by MSIs from that frame. A system may have multiple MSI frames, and separate frames may be defined for secure and non-secure access. This structure must only be used to describe non-secure MSI frames. SPI Count used by this frame. SPI Base used by this frame.

The mailbox is memory that the firmware reserves so that each processor can have the OS send a message to them. During system boot, the firmware puts the application processors in a state to check the mailbox. The firmware is not allowed to modify the mailbox location when the firmware transfer the control to an OS loader.

Only after the command is changed to Noop 0 , the OS can send the next command. The firmware section must be considered read-only to the OS and is only to be written to by the firmware.

Other processors can continue using the mailbox for the next command. Physical address of the mailbox. It must also be 4K bytes aligned. They are used to virtualize interrupts in tables and in ASL methods that perform resource allocation of interrupts. There are two interrupt models used in ACPI-enabled systems. The first model is the APIC model. This mapping is depicted in the following figure. If the platform supports batteries as defined by the Smart Battery Specification 1. This table indicates the energy level trip points that the platform requires for placing the system into the specified sleeping state and the suggested energy levels for warning the user to transition the platform into a sleeping state.

OSPM uses these tables with the capabilities of the batteries to determine the different trip points. For more precise definitions of these levels, see Section 3.

This optional table provides the processor-relative, translated resources of an Embedded Controller. The presence of this table allows OSPM to provide Embedded Controller operation region space access before the namespace has been evaluated.

If this table is not provided, the Embedded Controller region space will not be available until the Embedded Controller device in the AML namespace has been discovered and enumerated. Contains the processor-relative address, represented in Generic Address Structure format, of the Embedded Controller Data register. Quotes are omitted in the data field. See Section 6. Length, in bytes, of the entire SRAT.

The length implies the number of Entry fields at the end of the table. A list of static resource allocation structures for the platform. This allows system firmware to populate the SRAT with a static number of structures but only enable them as necessary. The Memory Affinity structure provides the following topology information statically to the operating system:.

Flags – Memory Affinity Structure. Indicates whether the region of memory is enabled and can be hot plugged. See the corresponding table below for more details. This allows system firmware to populate the SRAT with a static number of structures but only enable then as necessary. If the Enabled bit is set and the Hot Pluggable bit is also set. The system hardware supports hot-add and hot-remove of this memory region If the Enabled bit is set and the Hot Pluggable bit is clear, the system hardware does not support hot-add or hot-remove of this memory region.

The Generic Initiator Affinity Structure provides the association between a generic initiator and the proximity domain to which the initiator belongs. Device Handle of the Generic Initiator. Flags – Generic Initiator Affinity Structure. If set, indicates that the Generic Initiator can initiate all transactions at the same architectural level as the host e.

If a generic device with coherent memory is attached to the system, it is recommended to define affinity structures for both the device and memory associated with the device. They both may have the same proximity domain. Supporting a subset of architectural transactions would be only permissible if the lack of the feature does not have material consequences to the memory model. One example is lack of cache coherency support on the GI, if the GI does not have any local caches to global memory that require invalidation through the data fabric.

OS is assured that the GI adheres to the memory model as the host processor architecture related to observable transactions to memory for memory fences and other synchronization operations issued on either initiator or host. This optional table provides a matrix that describes the relative distance memory latency between all System Localities, which are also referred to as Proximity Domains.

The entry value is a one-byte unsigned integer. Except for the relative distance from a System Locality to itself, each relative distance is stored twice in the matrix. This provides the capability to describe the scenario where the relative distances for the two directions between System Localities is different. The diagonal elements of the matrix, the relative distances from a System Locality to itself are normalized to a value of The relative distances for the non-diagonal elements are scaled to be relative to For example, if the relative distance from System Locality i to System Locality j is 2.

If one locality is unreachable from another, a value of 0xFF is stored in that table entry. Distance values of are reserved and have no meaning. Platforms may contain the ability to detect and correct certain operational errors while maintaining platform function. These errors may be logged by the platform for the purpose of retrieval. Depending on the underlying hardware support, the means for retrieving corrected platform error information varies.

Alternatively, OSPM may poll processors for corrected platform error information. Error log information retrieved from a processor may contain information for all processors within an error reporting group. As such, it may not be necessary for OSPM to poll all processors in the system to retrieve complete error information. Length, in bytes, of the entire CPET. See corresponding table below. See corresponding table below for details of the Corrected Platform Error Polling Processor structure.

Indicates the maximum Physical Address ever possible in the system. Note: this is the top of the reachable physical address. A list of Proximity Domain Information for this implementation.

It is likely that these characteristics may be the same for many proximity domains, but they can vary from one proximity domain to another. This structure optimizes to cover the former case, while allowing the flexibility for the latter as well.

These structures must be organized in ascending order of the proximity domain enumerations. The starting proximity domain for the proximity domain range that this structure is providing information. The ending proximity domain for the proximity domain range that this structure is providing information. A value of 0 means that the proximity domains do not contain processors.

NOTE: There can be only on parameter block per type. Indicates that the platform supports hardware based patrol scrub of DRAM memory and platform exposes this capability to software using this RASF mechanism.

The configuration includes specifying memory power nodes and their associated information. Each memory power node is specified using address ranges, supported memory power states.

The memory power states will include both hardware controlled and software controlled memory power states. There can be multiple entries for a given memory power node to support non contiguous address ranges. MPST table also defines the communication mechanism between OSPM and platform runtime firmware for triggering software controlled memory powerstate transitions implemented in platform runtime firmware. Length in bytes for entire MPST. This field provides information on the memory power nodes present in the system.

Further details of this field are specified in Memory Power Node. This field provides information of memory power states supported in the system. The information includes power consumed, transition latencies, relevant flags. See the table below. All other command values are reserved. The PCC signature. The signature of a subspace is computed by a bitwise-or of the value 0x with the subspace ID. For example, subspace 3 has signature 0x PCC command field: see Section PCC status field: see Section Power State values will be based on the platform capability.

Memory Power State represents the state of a memory power node which maps to a memory address range while the platform is in the G0 working state.

In all three cases, these states require explicit OSPM action to isolate and free the memory address range for the corresponding memory power node. Power state transition diagram is shown in Fig.

If platform is capable of returning to a memory power state on subsequent period of idle, the platform must treat the previously requested memory power state as a persistent hint. This state value maps to active state of memory node Normal operation.

OSPM can access memory during this state. This state value can be mapped to any memory power state depending on the platform capability. By convention, it is required that low value power state will have lower power savings and lower latencies than the higher valued power states. SetMemoryPowerState : The following sequence needs to be done to set a memory power state. GetMemoryPowerState : The following sequence needs to be done to get the current memory power state.

Memory Power Node is a representation of a logical memory region that needs to be transitioned in and out of a memory power state as a unit. This logical memory region is made up of one more system memory address range s. Note that memory power node structure defined in Table 5. This address range should be 4K aligned. If a Memory Power Node contains more than one memory address range i. Memory Power Nodes are not hierarchical. OSPM is expected to identify the memory power node s that corresponds to the maximum memory address range that OSPM is able to power manage at a given time.

The following structure specifies the fields used for communicating memory power node information. Each entry in the MPST table will be having corresponding memory power node structure defined. This structure communicates address range, number of power states implemented, information about individual power states, number of distinct physical components that comprise this memory power node. The physical component identifiers can be cross-referenced against the memory topology table entries.

The flag describes type of memory node. See the Table 5. This field provides memory power node number. Length in bytes for Memory Power Node Structure. Low 32 bits of Length of the memory range. This field indicates number of power states supported for this memory power node and in turn determines the number of entries in memory power state structure. This field indicates the number of distinct Physical Components that constitute this memory power node. This field is also used to identify the number of entries of Physical Component Identifier entries present at end of this table.

This field provides information of various power states supported in the system for a given memory power node.

This allows system firmware to populate the MPST with a static number of structures but enable them as necessary. This flag indicates that the memory node supports the hot plug feature. See Interaction with Memory Hot Plug. This field provides value of power state. The specific value to be used is system dependent. However convention needs to be maintained where higher numbers indicates deeper power states with higher power savings and higher latencies. For example, a power state value of 2 will have higher power savings and higher latencies than a power state value of 1.

Refer to Table 5. This field provides average power consumed for this memory power node in MPS0 state. This power is measured in milliWatts and signifies the total power consumed by this memory the given power state as measured in DC watts.

Note that this value should be used as guideline only for estimating power savings and not as actual power consumed. The actual power consumed is dependent on DIMM type, configuration and memory load. The unit of this field is nanoseconds. If Bit [0] is set, it indicates memory contents will be preserved in the specified power state If Bit [0] is clear, it indicates memory contents will be lost in the specified power state e.

Not meaningful for MPS0 – write it for this table. If Bit [1] is set, this field indicates that given memory power state exit needs to be explicitly triggered by the OSPM before the memory can be accessed. System behavior is undefined if OSPM or other software agents attempt to access memory that is currently in a low power state. If Bit [1] is clear, this field indicates that given memory power state is exited automatically on access to the memory address range corresponding to the memory power node.

Exit Latency provided in the Memory Power Characteristics structure for a specific power state is inclusive of the entry latency for that state.

Platform firmware may have regions of memory reserved for its own use that are unavailable to OSPM for allocation. Memory nodes where all or a portion of the memory is reserved by platform firmware may pose a problem for OSPM because it does not know whether the platform firmware reserved memory is in use.

An example of policy which can be implemented in OSPM for memory coalescing is: OSPM can prefer allocating memory from local memory power nodes before going to remote memory power nodes. The later sections provide sample NUMA configurations and explain the policy for various memory power nodes. The hot pluggable memory regions are described using memory device objects see Section 9.

The memory power state table MPST is a static structure created for all memory objects independent of hot plug status online or offline during initialization.

Reference to memory in this document always refers to host physical memory. For virtualized environments, this requires hypervisors to be responsible for memory power management. Hypervisors also have the ability to create opportunities for memory power management by vacating appropriate host physical memory through remapping guest physical memory. This table describes the memory topology of the system to OSPM, where the memory topology can be logical or physical.

The topology is provided as a hierarchy of memory devices where the top level memory devices e. DIMMs associated with a parent memory device. The number of top level Memory Device structures that immediately follow. A zero in this field indicates no Memory Device structures follow. A list of memory device structures for the platform. Length in bytes for this structure.

The length includes the Type Specific Data, but not memory devices associated with this device. The number of Memory Devices associated with this device. Type specific data. Interpretation of this data is specific to the type of the memory device. It is not expected that OSPM will utilize this field. The Boot Graphics Resource Table BGRT is an optional table that provides a mechanism to indicate that an image was drawn on the screen during boot, and some information about the image.

The table is written when the image is drawn on the screen. This should be done after it is expected that any firmware components that may write to the screen are done doing so and it is known that the image is the only thing on the screen.

The image should be stored in EfiBootServicesData, allowing the system to reclaim the memory when the image is no longer needed. The Image Offset contains 2 consecutive 4 byte unsigned longs describing the X, Y display offset of the top left corner of the boot image.

This section describes the format of the Firmware Performance Data Table FPDT , which provides sufficient information to describe the platform initialization performance records. This information represents the boot performance data relating to specific tasks within the firmware boot process. The FPDT includes only those mileposts that are part of every platform boot process:. End of reset sequence Timer value noted at beginning of platform boot firmware initialization – typically at reset vector.

The format of the data is specific to the record type. In this manner, records are only as large as needed to contain the specific type of data to be conveyed. Note that unless otherwise specified, multiple records are permitted for a given type, because some events may occur multiple times during the boot process. This value is updated if the format of the record type is extended. Any changes to a performance record layout must be backwards-compatible in that all previously defined fields must be maintained if still applicable, but newly defined fields allow the length of the performance record to be increased.

Previously defined record fields must not be redefined, but are permitted to be deprecated. The table below describes the various Runtime Performance records and their corresponding Record Types.

Only one of these records will be produced. The record pointer is a required entry in the FPDT for any system supporting the S3 state, and the pointer must point to a valid static physical address. It includes a header, defined in Table 5. All event entries will be overwritten during the platform runtime firmware S4 resume sequence. Other entries are optional. This includes the header and allocated size of the subsequent records. The Firmware Basic Boot Performance Data Record contains timer information associated with final OS loader activity, as well as data associated with boot time starting and ending information.

Timer value logged at the beginning of firmware image execution. This may not always be zero or near zero. Timer value logged just prior to loading the OS boot loader into memory. For non-UEFI compatible boots, this field must be zero. Timer value logged just prior to launching the currently loaded OS boot loader image.

Note that the entire log of timer values does not need to be retained in order to calculate this average. The bit physical address at which the Counter Control block is located. This value is optional if the system implements EL3 Security Extensions. This value is optional, as an operating system executing in the non-secure world EL2 or EL1 , will ignore the content of these fields. Flags for the secure EL1 timer defined below. This value is optional, as an operating system executing in the non-secure world EL2 or EL1 will ignore the content of this field.

The bit physical address at which the Counter Read block is located. This field is mandatory for systems implementing ARMv8. For systems not implementing ARMv8. Flags for the virtual EL2 timer defined below. Array of Platform Timer Type structures describing memory-mapped Timers available on this platform. These structures are described in the sections below. These timers are in addition to the per-processor timers described above them in the GTDT.

The first byte of each structure declares the type of that structure and the second and third bytes declare the length of that structure. The GT Block is a standard timer block that is mapped into the system address space. Flags for the GTx physical timer. Flags for the GTx virtual timer, if implemented. Interleave Structure s see Section 5. Flush Hint Address Structure s see Section 5. Platform Capabilities Structure see Section 5.

The following figure illustrates the above structures and how they are associated with each other. This allows OSPM to ignore unrecognized types. Platform is allowed to implement this structure just to describe system physical address ranges that describe Virtual CD and Virtual Disk. Value of 0 is Reserved and shall not be used as an index. Integer that represents the proximity domain to which the memory belongs. This number must match with corresponding entry in the SRAT table.

The final version of Macromedia Studio released include:. Adobe Creative Suite 3 CS3 was announced on March 27, ; it introduced universal binaries for all major programs for the Apple Macintosh , [19] as well as including all of the core applications from Macromedia Studio and Production Studio. Some Creative Suite programs also began using the Presto layout engine used in the Opera web browser.

Adobe began selling CS3 applications in six different combinations called “editions. The latest released CS3 version was version 3.

CS3 included several programs, including Dreamweaver , Flash Professional , and Fireworks that were developed by Macromedia , a former rival acquired by Adobe in Adobe dropped the following programs that were previously included in CS2 from the CS3 software bundles: [22]. Adobe had announced that it would continue to develop Audition as a standalone product, while GoLive had been discontinued. Adobe GoLive 9 was released as a standalone product on June 10, Adobe Audition 3 was announced as a standalone product on September 6, Adobe had discontinued ImageReady and had replaced it with Fireworks, with some of ImageReady’s features integrated into Photoshop.

Audition became part of the Creative Suite again in CS5. Adobe CS4 was also developed to perform better under bit and multi-core processors. Two programs were dropped from the CS4 line-up: Adobe Ultra , a vector keying application which utilizes image analysis technology to produce high quality chroma key effects in less than ideal lighting environments and provides keying of a subject into a virtual 3D environment through virtual set technology, and Adobe Stock Photos.

Below is a matrix of the applications that were bundled in each of the software suites for CS Following the release of CS5 in April , Adobe changed its release strategy to an every other year release of major number installments. The update helped developers optimize websites for a variety of tablets, smart phones, and other devices. At the same time, Adobe announced a subscription-based pay service as an alternative to full purchase.

Not all products were upgraded to CS5. Below is a matrix of the applications that were bundled in each of the software suites for CS5. On May 5, , during the opening keynote of its Adobe MAX conference, Adobe announced that it was retiring the “Creative Suite” branding in favor of “Creative Cloud”, and making all future feature updates to its software now appended with “CC” instead of “CS”, e.

Photoshop CC available via the Creative Cloud subscription service rather than through the purchasing of perpetual licenses. Customers must pay a subscription fee and if they stop paying, they will lose access to the proprietary file formats , [39] [40] which are not backward-compatible with the Creative Suite [41] [42] Adobe admitted that this is a valid concern [43].

Individual subscribers must have an Internet connection [44] to download the software and to use the 2 GB of provided storage space or the additionally purchased 20 GB [45] , and must validate the license monthly. Adobe’s decision to make the subscription service the only sales route for its creative software was met with strong criticism [47] [48] see Creative Cloud controversy.

In addition to many of the products formerly part of the Creative Suite one product, Fireworks, was announced as having reached the end of its development cycle , [56] Creative Cloud also offers subscription-exclusive products such as Adobe Muse [57] and the Adobe Edge family, [57] Web-based file and website hosting, Typekit fonts, and access to the Behance social media platform. New versions with major feature updates have been released regularly, with a refresh of the file formats occurring in October Adobe also announced that it would continue to offer bug fixes for the CS6 products so that they will continue to run on the next versions of Microsoft Windows and Apple OS X.

On other system architectures, the entire field should be set to 0. User-visible devices are devices that have end-user accessible connectors for example, LPT port , or devices for which the OS must load a device driver so that an end-user application can use a device.

For more information, see Section This value is 64 bytes or larger. This value is calculated by the platform boot firmware on a best effort basis to indicate the base hardware configuration of the system such that different base hardware configurations can have different hardware signature values.

Before transitioning the system into a global sleeping state, OSPM fills in this field with the physical memory address of an OS-specific wake function. On PCs, the wake function address is in memory below 1 MB and the control is transferred while in real mode. If, for example, the physical address is 0x, then the BIOS must jump to real mode address 0xx This field contains the Global Lock used to synchronize access to shared hardware resources between the OSPM environment and an external controller environment for example, the SMI environment.

For example, the Global Lock can be used to protect an embedded controller interface such that only OSPM or the firmware will access the embedded controller interface at any one time. Memory address translation must be disabled The processor must have psr. For IA 32 and x64 platforms, platform firmware is required to support a 32 bit execution environment.

Platform firmware can additionally support a 64 bit execution environment. Otherwise, the platform firmware creates a 32 bit execution environment. IF set to 0 Long mode enabled Paging mode is enabled and physical memory for waking vector is identity mapped virtual address equals physical address Waking vector must be contained within one physical page Selectors are set to be flat and are otherwise not used For 32 bit execution environment: Interrupts must be disabled EFLAGS.

If non-zero is returned, the caller must raise the appropriate event to the other environment to signal that the Global Lock is now free. This signal only occurs when the other environment attempted to acquire ownership while the lock was owned. Although using the Global Lock allows various hardware resources to be shared, it is important to notice that its usage when there is ownership contention could entail a significant amount of system overhead as well as waits of an indeterminate amount of time to acquire ownership of the Global Lock.

The power of the Definition block comes from its ability to allow these operations to be glued together in numerous ways, to provide functionality to OSPM. The AML operators defined in this specification are intended to allow many useful hardware designs to be easily expressed, not to allow all hardware designs to be expressed.

Existing ACPI definition block implementations may contain an inherent assumption of a bit integer width. Therefore, to maintain backwards compatibility, OSPM uses the Revision field, in the header portion of system description tables containing Definition Blocks, to determine whether integers declared within the Definition Block are to be evaluated as bit or bit values.

A Revision field value greater than or equal to 2 signifies that integers declared within the Definition Block are to be evaluated as bit values. See Section This field also sets the global integer width for the AML interpreter. Values less than two will cause the interpreter to use bit integers and math. Values of two and greater will cause the interpreter to use full bit integers and math.

There can be multiple SSDTs present. This allows the OEM to provide the base support in one table and add smaller system options in other tables.

For example, the OEM might put dynamic object definitions into a secondary table such that the firmware can construct the dynamic information at boot without needing to edit the static DSDT. The ACPI interrupt model describes all interrupts for the entire system in a uniform interrupt model implementation. The choice of the interrupt model s to support is up to the platform designer.

Platform designers must allow for this. Only legacy systems should continue with this usage. A list of interrupt controller structures for this implementation. This list will contain all of the structures from Interrupt Controller Structure Types needed to support this platform. These structures are described in the following sections. A one indicates that the system also has a PC-AT-compatible dual setup. Immediately after the Flags value in the MADT is a list of interrupt controller structures that declare the interrupt features of the machine.

The first byte of each structure declares the type of that structure and the second byte declares the length of that structure. OSPM implementations may limit the number of supported processors on multi-processor platforms. OSPM executes on the boot processor to initialize the platform including other processors. To ensure that the boot processor is supported post initialization, two guidelines should be followed. The second is that platform firmware should list the boot processor as the first processor entry in the MADT.

The advent of multi-threaded processors yielded multiple logical processors executing on common processor hardware. ACPI defines logical processors in an identical manner as physical processors. To ensure that non multi-threading aware OSPM implementations realize optimal performance on platforms containing multi-threaded processors, two guidelines should be followed. The second is that platform firmware should list the first logical processor of each of the individual multi-threaded processors in the MADT before listing any of the second logical processors.

This approach should be used for all successive logical processors. Failure of OSPM implementations and platform firmware to abide by these guidelines can result in both unpredictable and non optimal platform operation.

Interrupt Source Overrides are also necessary when an identity mapped interrupt input has a non-standard polarity. Any source that is non-maskable will not be available for use by devices.

If a platform can generate an interrupt after correcting platform errors e. Some systems may restrict the retrieval of corrected platform error information to a specific processor. In such cases, the firmware indicates the processor that can retrieve the corrected platform error information through the Processor ID and EID fields in the structure below.

It is allowed for such an entry to refer to a Global System Interrupt that is already specified by a Platform Interrupt Source Structure provided through the static MADT table, provided the value of platform interrupt source flags are identical. Platform Interrupt Source Flags. See Platform Interrupt Source Flags for a description of this field. When a logical processor is not present, the processor local X2APIC information is either not reported or flagged as disabled.

If all of the GIC Redistributors are in the always-on power domain, GICR structures should be used to describe the Redistributors instead, and this field must be set to 0. Describes the relative power efficiency of the associated processor. Lower efficiency class numbers are more efficient than higher ones e. This interrupt is a level triggered PPI. Zero if SPE is not supported by this processor.

If zero, this processor is unusable, and the operating system support will not attempt to use it. The frame also includes registers to discover the set of distributor lines which may be signaled by MSIs from that frame. A system may have multiple MSI frames, and separate frames may be defined for secure and non-secure access. This structure must only be used to describe non-secure MSI frames.

The firmware section must be considered read-only to the OS and is only to be written to by the firmware.

It must also be 4K bytes aligned. They are used to virtualize interrupts in tables and in ASL methods that perform resource allocation of interrupts. There are two interrupt models used in ACPI-enabled systems.

A list of static resource allocation structures for the platform. This allows system firmware to populate the SRAT with a static number of structures but only enable them as necessary. The Memory Affinity structure provides the following topology information statically to the operating system:. Flags – Memory Affinity Structure. Indicates whether the region of memory is enabled and can be hot plugged. See the corresponding table below for more details. This allows system firmware to populate the SRAT with a static number of structures but only enable then as necessary.

If the Enabled bit is set and the Hot Pluggable bit is also set. The system hardware supports hot-add and hot-remove of this memory region If the Enabled bit is set and the Hot Pluggable bit is clear, the system hardware does not support hot-add or hot-remove of this memory region. See the corresponding table below for a description of this field.

Device Handle of the Generic Initiator. Flags – Generic Initiator Affinity Structure. If set, indicates that the Generic Initiator can initiate all transactions at the same architectural level as the host e. If a generic device with coherent memory is attached to the system, it is recommended to define affinity structures for both the device and memory associated with the device.

The diagonal elements of the matrix, the relative distances from a System Locality to itself are normalized to a value of The relative distances for the non-diagonal elements are scaled to be relative to For example, if the relative distance from System Locality i to System Locality j is 2.

Depending on the underlying hardware support, the means for retrieving corrected platform error information varies.

Length, in bytes, of the entire CPET. See corresponding table below. See corresponding table below for details of the Corrected Platform Error Polling Processor structure. If the system maximum topology is not known up front at boot time, then this table is not present. Indicates the maximum number of Proximity Domains ever possible in the system. The number reported in this field is maximum domains – 1. For example if there are 0x possible domains in the system, this field would report 0xFFFF.

Indicates the maximum number of Clock Domains ever possible in the system. Indicates the maximum Physical Address ever possible in the system. Note: this is the top of the reachable physical address.

The ending proximity domain for the proximity domain range that this structure is providing information. A value of 0 means that the proximity domains do not contain processors. A value of 0 means that the proximity domains do not contain memory. Length in bytes for entire RASF. The Platform populates this field. The Bit Map is described in Section 5. These parameter blocks are used as communication mailbox between the OSPM and the platform, and there is 1 parameter block for each RAS feature.

The structure is used to pass parameters for controlling the corresponding RAS Feature. The platform calculates the nearest patrol scrub boundary address from where it can start. This range should be a superset of the Requested Address Range. The following sequence documents the steps for OSPM to identify whether the platform supports hardware based patrol scrub and invoke commands to request hardware to patrol scrub the specified address range.

Each memory power node is specified using address ranges, supported memory power states. The memory power states will include both hardware controlled and software controlled memory power states. There can be multiple entries for a given memory power node to support non contiguous address ranges. MPST table also defines the communication mechanism between OSPM and platform runtime firmware for triggering software controlled memory powerstate transitions implemented in platform runtime firmware.

Length in bytes for entire MPST. This field provides information on the memory power nodes present in the system. Further details of this field are specified in Memory Power Node. This field provides information of memory power states supported in the system. The information includes power consumed, transition latencies, relevant flags.

See the table below. All other command values are reserved. The PCC signature. The signature of a subspace is computed by a bitwise-or of the value 0x with the subspace ID.

It only indicates that any active state memory power management in MPS0 is transparent to the OSPM and more importantly does not require assist from OSPM in terms of restricting memory occupancy and activity. In all three cases, these states require explicit OSPM action to isolate and free the memory address range for the corresponding memory power node. Power state transition diagram is shown in Fig. If platform is capable of returning to a memory power state on subsequent period of idle, the platform must treat the previously requested memory power state as a persistent hint.

This state value maps to active state of memory node Normal operation.

This structure must only be used to describe non-secure MSI frames. SPI Count used by this frame. SPI Base used by this frame.

GICR structures should only be used when describing GIC implementations which conform to version 3 or higher of the GIC architecture and which place all Redistributors in the always-on power domain. The platform firmware publishes a multiprocessor wakeup structure to let the bootstrap processor wake up application processors with a mailbox. The mailbox is memory that the firmware reserves so that each processor can have the OS send a message to them. During system boot, the firmware puts the application processors in a state to check the mailbox.

The firmware is not allowed to modify the mailbox location when the firmware transfer the control to an OS loader. The mailbox is broken down into two 2KB sections: an OS section and a firmware section. The OS section can only be written by OS and read by the firmware, except the command field. The application processor need clear the command to Noop 0 as the acknowledgement that the command is received.

The firmware must cache the content in the mailbox which might be used later before clear the command such as WakeupVector. Only after the command is changed to Noop 0 , the OS can send the next command. The firmware section must be considered read-only to the OS and is only to be written to by the firmware. All data communication between the OS and FW must be in little endian format.

For each application processor, the mailbox can be used only once for the wakeup command. After the application process takes the action according to the command, this mailbox will no longer be checked by this application processor. Other processors can continue using the mailbox for the next command. Physical address of the mailbox. It must also be 4K bytes aligned. They are used to virtualize interrupts in tables and in ASL methods that perform resource allocation of interrupts.

There are two interrupt models used in ACPI-enabled systems. The first model is the APIC model. This mapping is depicted in the following figure. If the platform supports batteries as defined by the Smart Battery Specification 1. This table indicates the energy level trip points that the platform requires for placing the system into the specified sleeping state and the suggested energy levels for warning the user to transition the platform into a sleeping state.

The presence of this table allows OSPM to provide Embedded Controller operation region space access before the namespace has been evaluated. If this table is not provided, the Embedded Controller region space will not be available until the Embedded Controller device in the AML namespace has been discovered and enumerated.

A list of static resource allocation structures for the platform. This allows system firmware to populate the SRAT with a static number of structures but only enable them as necessary.

The Memory Affinity structure provides the following topology information statically to the operating system:. Flags – Memory Affinity Structure. Indicates whether the region of memory is enabled and can be hot plugged. See the corresponding table below for more details. This allows system firmware to populate the SRAT with a static number of structures but only enable then as necessary.

See the corresponding table below for a description of this field. This enables the OSPM to discover the memory that is closest to the ITS, and use that in allocating its management tables and command queue. The Generic Initiator Affinity Structure provides the association between a generic initiator and the proximity domain to which the initiator belongs. Device Handle of the Generic Initiator. Flags – Generic Initiator Affinity Structure. If set, indicates that the Generic Initiator can initiate all transactions at the same architectural level as the host e.

Supporting a subset of architectural transactions would be only permissible if the lack of the feature does not have material consequences to the memory model. One example is lack of cache coherency support on the GI, if the GI does not have any local caches to global memory that require invalidation through the data fabric.

Except for the relative distance from a System Locality to itself, each relative distance is stored twice in the matrix. This provides the capability to describe the scenario where the relative distances for the two directions between System Localities is different. The diagonal elements of the matrix, the relative distances from a System Locality to itself are normalized to a value of The relative distances for the non-diagonal elements are scaled to be relative to For example, if the relative distance from System Locality i to System Locality j is 2.

These errors may be logged by the platform for the purpose of retrieval. Depending on the underlying hardware support, the means for retrieving corrected platform error information varies. Alternatively, OSPM may poll processors for corrected platform error information. Error log information retrieved from a processor may contain information for all processors within an error reporting group. As such, it may not be necessary for OSPM to poll all processors in the system to retrieve complete error information.

Indicates the maximum number of Proximity Domains ever possible in the system. The number reported in this field is maximum domains – 1.

For example if there are 0x possible domains in the system, this field would report 0xFFFF. Indicates the maximum number of Clock Domains ever possible in the system. Indicates the maximum Physical Address ever possible in the system.

Note: this is the top of the reachable physical address. A list of Proximity Domain Information for this implementation. It is likely that these characteristics may be the same for many proximity domains, but they can vary from one proximity domain to another. This structure optimizes to cover the former case, while allowing the flexibility for the latter as well.

A value of 0 means that the proximity domains do not contain memory. Length in bytes for entire RASF. The Platform populates this field. The Bit Map is described in Section 5. These parameter blocks are used as communication mailbox between the OSPM and the platform, and there is 1 parameter block for each RAS feature. NOTE: There can be only on parameter block per type. Indicates that the platform supports hardware based patrol scrub of DRAM memory and platform exposes this capability to software using this RASF mechanism.

The following table describes the Parameter Blocks. The structure is used to pass parameters for controlling the corresponding RAS Feature.

The platform calculates the nearest patrol scrub boundary address from where it can start. This range should be a superset of the Requested Address Range.

The following sequence documents the steps for OSPM to identify whether the platform supports hardware based patrol scrub and invoke commands to request hardware to patrol scrub the specified address range. Identify whether the platform supports hardware based patrol scrub and exposes the support to software by reading the RAS capabilities bitmap in the RASF table. This table defines the memory power node topology of the configuration, as described earlier in Section 1.

The configuration includes specifying memory power nodes and their associated information. Each memory power node is specified using address ranges, supported memory power states. The memory power states will include both hardware controlled and software controlled memory power states.

There can be multiple entries for a given memory power node to support non contiguous address ranges. MPST table also defines the communication mechanism between OSPM and platform runtime firmware for triggering software controlled memory powerstate transitions implemented in platform runtime firmware. Length in bytes for entire MPST. This field provides information on the memory power nodes present in the system. Further details of this field are specified in Memory Power Node.

This field provides information of memory power states supported in the system. The information includes power consumed, transition latencies, relevant flags. See the table below. All other command values are reserved. The PCC signature. The signature of a subspace is computed by a bitwise-or of the value 0x with the subspace ID. For example, subspace 3 has signature 0x PCC command field: see Section PCC status field: see Section Power State values will be based on the platform capability.

A value of all 1s in this field indicates that platform does not implement this field. OSPM should use the ratio of computed memory power consumed to expected average power consumed in determining the memory power management action. Memory Power State represents the state of a memory power node which maps to a memory address range while the platform is in the G0 working state.

This state value maps to active state of memory node Normal operation. OSPM can access memory during this state.

This state value can be mapped to any memory power state depending on the platform capability. By convention, it is required that low value power state will have lower power savings and lower latencies than the higher valued power states. SetMemoryPowerState : The following sequence needs to be done to set a memory power state.

GetMemoryPowerState : The following sequence needs to be done to get the current memory power state. Memory Power Node is a representation of a logical memory region that needs to be transitioned in and out of a memory power state as a unit. This logical memory region is made up of one more system memory address range s. Note that memory power node structure defined in Table 5. This address range should be 4K aligned. If a Memory Power Node contains more than one memory address range i.

Each entry in the MPST table will be having corresponding memory power node structure defined. This structure communicates address range, number of power states implemented, information about individual power states, number of distinct physical components that comprise this memory power node.

Low 32 bits of Length of the memory range. This field indicates number of power states supported for this memory power node and in turn determines the number of entries in memory power state structure. This field indicates the number of distinct Physical Components that constitute this memory power node. This field is also used to identify the number of entries of Physical Component Identifier entries present at end of this table.

This field provides information of various power states supported in the system for a given memory power node. This allows system firmware to populate the MPST with a static number of structures but enable them as necessary. This flag indicates that the memory node supports the hot plug feature. See Interaction with Memory Hot Plug. This field provides value of power state.

The specific value to be used is system dependent. However convention needs to be maintained where higher numbers indicates deeper power states with higher power savings and higher latencies. For example, a power state value of 2 will have higher power savings and higher latencies than a power state value of 1.

This field provides unique index into the memory power state characteristics entries which will provide details about the power consumed, power state characteristics and transition latencies.

The indexing mechanism is to avoid duplication and hence reduce potential for mismatch errors of memory power state characteristics entries across multiple memory nodes. The table below describes the power consumed, exit latency and the characteristics of the memory power state. This table is referenced by a memory power node. The flag describes the caveats associated with entering the specified power state. Refer to Table 5.

This field provides average power consumed for this memory power node in MPS0 state. This power is measured in milliWatts and signifies the total power consumed by this memory the given power state as measured in DC watts. Note that this value should be used as guideline only for estimating power savings and not as actual power consumed.

The actual power consumed is dependent on DIMM type, configuration and memory load. The unit of this field is nanoseconds. If Bit [0] is set, it indicates memory contents will be preserved in the specified power state If Bit [0] is clear, it indicates memory contents will be lost in the specified power state e. If Bit [1] is set, this field indicates that given memory power state entry transition needs to be triggered explicitly by OSPM by calling the Set Power State command.

If Bit [1] is clear, this field indicates that given memory power state entry transition is automatically implemented in hardware and does not require a OSPM trigger. The role of OSPM in this case is to ensure that the corresponding memory region is idled from a software standpoint to facilitate entry to the state.

If Bit [1] is clear, this field indicates that given memory power state is exited automatically on access to the memory address range corresponding to the memory power node. Exit Latency provided in the Memory Power Characteristics structure for a specific power state is inclusive of the entry latency for that state.

Not all memory power management states require OSPM to actively transition a memory power node in and out of the memory power state. Platforms may implement memory power states that are fully handled in hardware in terms of entry and exit transition. In such fully autonomous states, the decision to enter the state is made by hardware based on the utilization of the corresponding memory region and the decision to exit the memory power state is initiated in response to a memory access targeted to the corresponding memory region.

The role of OSPM software in handling such autonomous memory power states is to vacate the use of such memory regions when possible in order to allow hardware to effectively save power. No other OSPM initiated action is required for supporting these autonomously power managed regions. However, it is not an error for OSPM explicitly initiates a state transition to an autonomous entry memory power state through the MPST command interface.

This allows OSPM to ignore such ranges from its memory power optimization. The memory power state table describes address range for each of the memory power nodes specified. An example of policy which can be implemented in OSPM for memory coalescing is: OSPM can prefer allocating memory from local memory power nodes before going to remote memory power nodes.

The later sections provide sample NUMA configurations and explain the policy for various memory power nodes. The hot pluggable memory regions are described using memory device objects see Section 9. The memory power state table MPST is a static structure created for all memory objects independent of hot plug status online or offline during initialization. The association between memory device object e. It is recommended that the OSes if possible allocate this memory from memory ranges corresponding to memory power nodes that indicate they are not power manageable.

Type specific data. Interpretation of this data is specific to the type of the memory device. It is not expected that OSPM will utilize this field. The Boot Graphics Resource Table BGRT is an optional table that provides a mechanism to indicate that an image was drawn on the screen during boot, and some information about the image. The table is written when the image is drawn on the screen. This should be done after it is expected that any firmware components that may write to the screen are done doing so and it is known that the image is the only thing on the screen.

The version field identifies which revision of the BGRT table is implemented. The version field should be set to 1. The Image type field contains information about the format of the image being returned. If the value is 0, the Image Type is Bitmap. The Image Address contains the location in memory where an in-memory copy of the boot image can be found.

The image should be stored in EfiBootServicesData, allowing the system to reclaim the memory when the image is no longer needed.

End of reset sequence Timer value noted at beginning of platform boot firmware initialization – typically at reset vector. All timer values are express in 1 nanosecond increments.

For example, if a record indicates an event occurred at a timer value of , this means that For the Firmware Performance Data Table conforming to this revision of the specification, the revision is 1. A performance record is comprised of a sub-header including a record type and length, and a set of data. The format of the data is specific to the record type. In this manner, records are only as large as needed to contain the specific type of data to be conveyed.

Creative Suite helped InDesign become the dominant publishing software, replacing QuarkXPress , because customers who purchased the suite for Photoshop and Illustrator received InDesign at no additional cost.

Adobe shut down the “activation” servers for CS2 in December , making it impossible for licensed users to reinstall the software if needed.

In response to complaints, Adobe then made available for download a version of CS2 that did not require online activation, and published a serial number to activate it offline. Adobe Creative Suite Production Studio previously Adobe Video Collection was a suite of programs for acquiring, editing, and distributing digital video and audio that was released during the same timeframe as Adobe Creative Suite 2. The suite was available in standard and premium editions.

Macromedia Studio was a suite of programs designed for web content creation designed and distributed by Macromedia. After Adobe ‘s acquisition of Macromedia, Macromedia Studio 8 was replaced, modified, and integrated into two editions of the Adobe Creative Suite family of software from version 2.

Some Macromedia applications were absorbed into existing Adobe products, e. FreeHand has been replaced with Adobe Illustrator. Director and ColdFusion are not part of Adobe Creative Suite and will only be available as standalone products. The final version of Macromedia Studio released include:. Adobe Creative Suite 3 CS3 was announced on March 27, ; it introduced universal binaries for all major programs for the Apple Macintosh , [19] as well as including all of the core applications from Macromedia Studio and Production Studio.

Some Creative Suite programs also began using the Presto layout engine used in the Opera web browser. Adobe began selling CS3 applications in six different combinations called “editions. The latest released CS3 version was version 3. CS3 included several programs, including Dreamweaver , Flash Professional , and Fireworks that were developed by Macromedia , a former rival acquired by Adobe in Adobe dropped the following programs that were previously included in CS2 from the CS3 software bundles: [22].

Adobe had announced that it would continue to develop Audition as a standalone product, while GoLive had been discontinued. Adobe GoLive 9 was released as a standalone product on June 10, Adobe Audition 3 was announced as a standalone product on September 6, Adobe had discontinued ImageReady and had replaced it with Fireworks, with some of ImageReady’s features integrated into Photoshop.

Audition became part of the Creative Suite again in CS5. Adobe CS4 was also developed to perform better under bit and multi-core processors. Two programs were dropped from the CS4 line-up: Adobe Ultra , a vector keying application which utilizes image analysis technology to produce high quality chroma key effects in less than ideal lighting environments and provides keying of a subject into a virtual 3D environment through virtual set technology, and Adobe Stock Photos.

Length, in bytes, of the entire SRAT. The length implies the number of Entry fields at the end of the table. A list of static resource allocation structures for the platform. This allows system firmware to populate the SRAT with a static number of structures but only enable them as necessary. The Memory Affinity structure provides the following topology information statically to the operating system:. Flags – Memory Affinity Structure. Indicates whether the region of memory is enabled and can be hot plugged.

See the corresponding table below for more details. This allows system firmware to populate the SRAT with a static number of structures but only enable then as necessary. If the Enabled bit is set and the Hot Pluggable bit is also set.

The Generic Initiator Affinity Structure provides the association between a generic initiator and the proximity domain to which the initiator belongs. Device Handle of the Generic Initiator.

Flags – Generic Initiator Affinity Structure. If set, indicates that the Generic Initiator can initiate all transactions at the same architectural level as the host e. If a generic device with coherent memory is attached to the system, it is recommended to define affinity structures for both the device and memory associated with the device.

They both may have the same proximity domain. Supporting a subset of architectural transactions would be only permissible if the lack of the feature does not have material consequences to the memory model. One example is lack of cache coherency support on the GI, if the GI does not have any local caches to global memory that require invalidation through the data fabric. OS is assured that the GI adheres to the memory model as the host processor architecture related to observable transactions to memory for memory fences and other synchronization operations issued on either initiator or host.

This optional table provides a matrix that describes the relative distance memory latency between all System Localities, which are also referred to as Proximity Domains. The entry value is a one-byte unsigned integer. Except for the relative distance from a System Locality to itself, each relative distance is stored twice in the matrix. This provides the capability to describe the scenario where the relative distances for the two directions between System Localities is different.

As such, it may not be necessary for OSPM to poll all processors in the system to retrieve complete error information. Length, in bytes, of the entire CPET. See corresponding table below. See corresponding table below for details of the Corrected Platform Error Polling Processor structure. If the system maximum topology is not known up front at boot time, then this table is not present. Indicates the maximum number of Proximity Domains ever possible in the system.

The number reported in this field is maximum domains – 1. For example if there are 0x possible domains in the system, this field would report 0xFFFF. Indicates the maximum number of Clock Domains ever possible in the system. Indicates the maximum Physical Address ever possible in the system. Note: this is the top of the reachable physical address.

Length in bytes for entire RASF. The Platform populates this field. The Bit Map is described in Section 5. These parameter blocks are used as communication mailbox between the OSPM and the platform, and there is 1 parameter block for each RAS feature.

Identify whether the platform supports hardware based patrol scrub and exposes the support to software by reading the RAS capabilities bitmap in the RASF table. This table defines the memory power node topology of the configuration, as described earlier in Section 1. The configuration includes specifying memory power nodes and their associated information. Each memory power node is specified using address ranges, supported memory power states. The memory power states will include both hardware controlled and software controlled memory power states.

See the table below. All other command values are reserved. The PCC signature. The signature of a subspace is computed by a bitwise-or of the value 0x with the subspace ID.

For example, subspace 3 has signature 0x PCC command field: see Section PCC status field: see Section Power State values will be based on the platform capability. A value of all 1s in this field indicates that platform does not implement this field. OSPM should use the ratio of computed memory power consumed to expected average power consumed in determining the memory power management action. Memory Power State represents the state of a memory power node which maps to a memory address range while the platform is in the G0 working state.

It should be noted that active memory power state MPS0 does not preclude memory power management in that state. It only indicates that any active state memory power management in MPS0 is transparent to the OSPM and more importantly does not require assist from OSPM in terms of restricting memory occupancy and activity. In all three cases, these states require explicit OSPM action to isolate and free the memory address range for the corresponding memory power node.

Power state transition diagram is shown in Fig. If platform is capable of returning to a memory power state on subsequent period of idle, the platform must treat the previously requested memory power state as a persistent hint. This state value maps to active state of memory node Normal operation.

SetMemoryPowerState : The following sequence needs to be done to set a memory power state. GetMemoryPowerState : The following sequence needs to be done to get the current memory power state. Memory Power Node is a representation of a logical memory region that needs to be transitioned in and out of a memory power state as a unit. This logical memory region is made up of one more system memory address range s.

Note that memory power node structure defined in Table 5. This address range should be 4K aligned. If a Memory Power Node contains more than one memory address range i. Memory Power Nodes are not hierarchical. OSPM is expected to identify the memory power node s that corresponds to the maximum memory address range that OSPM is able to power manage at a given time.

This flag indicates that the memory node supports the hot plug feature. See Interaction with Memory Hot Plug. This field provides value of power state. The specific value to be used is system dependent. However convention needs to be maintained where higher numbers indicates deeper power states with higher power savings and higher latencies.

For example, a power state value of 2 will have higher power savings and higher latencies than a power state value of 1. This field provides unique index into the memory power state characteristics entries which will provide details about the power consumed, power state characteristics and transition latencies.

Exit Latency provided in the Memory Power Characteristics structure for a specific power state is inclusive of the entry latency for that state. Not all memory power management states require OSPM to actively transition a memory power node in and out of the memory power state. Platforms may implement memory power states that are fully handled in hardware in terms of entry and exit transition. In such fully autonomous states, the decision to enter the state is made by hardware based on the utilization of the corresponding memory region and the decision to exit the memory power state is initiated in response to a memory access targeted to the corresponding memory region.

The association between memory device object e. It is recommended that the OSes if possible allocate this memory from memory ranges corresponding to memory power nodes that indicate they are not power manageable. This allows OS to optimize the power manageable memory power nodes for optimal power savings.

OSes can assume that memory ranges that belong to memory power nodes that are power manageable as indicated by the flag are interleaved in a manner that does no impact the ability of that range to enter power managed states.

Hypervisors also have the ability to create opportunities for memory power management by vacating appropriate host physical memory through remapping guest physical memory. This table describes the memory topology of the system to OSPM, where the memory topology can be logical or physical. The topology is provided as a hierarchy of memory devices where the top level memory devices e.

Length in bytes for this structure. The length includes the Type Specific Data, but not memory devices associated with this device. The number of Memory Devices associated with this device. Type specific data. Interpretation of this data is specific to the type of the memory device. It is not expected that OSPM will utilize this field. The Boot Graphics Resource Table BGRT is an optional table that provides a mechanism to indicate that an image was drawn on the screen during boot, and some information about the image.

The Image type field contains information about the format of the image being returned. If the value is 0, the Image Type is Bitmap. The Image Address contains the location in memory where an in-memory copy of the boot image can be found. The image should be stored in EfiBootServicesData, allowing the system to reclaim the memory when the image is no longer needed.

The FPDT includes only those mileposts that are part of every platform boot process:. End of reset sequence Timer value noted at beginning of platform boot firmware initialization – typically at reset vector.

All timer values are express in 1 nanosecond increments. For example, if a record indicates an event occurred at a timer value of , this means that For the Firmware Performance Data Table conforming to this revision of the specification, the revision is 1. A performance record is comprised of a sub-header including a record type and length, and a set of data. The format of the data is specific to the record type. In this manner, records are only as large as needed to contain the specific type of data to be conveyed.

Previously defined record fields must not be redefined, but are permitted to be deprecated. The table below describes the various Runtime Performance records and their corresponding Record Types.

Performance record showing basic performance metrics for critical phases of the firmware boot process. The record pointer is a required entry in the FPDT for any system, and the pointer must point to a valid static physical address. Only one of these records will be produced. The record pointer is a required entry in the FPDT for any system supporting the S3 state, and the pointer must point to a valid static physical address. It includes a header, defined in Table 5. All event entries will be overwritten during the platform runtime firmware S4 resume sequence.

Other entries are optional. This includes the header and allocated size of the subsequent records. The Firmware Basic Boot Performance Data Record contains timer information associated with final OS loader activity, as well as data associated with boot time starting and ending information. Timer value logged at the beginning of firmware image execution. This may not always be zero or near zero. Timer value logged just prior to loading the OS boot loader into memory. For non-UEFI compatible boots, this field must be zero.

Timer value logged just prior to launching the currently loaded OS boot loader image. All event entries must be initialized to zero during the initial boot sequence, and overwritten during the platform runtime firmware S3 resume sequence. Length of the S3 Performance Table. This size would at minimum include the size of the header and the Basic S3 Resume Performance Record. Timer recorded at the end of platform runtime firmware S3 resume, just prior to handoff to the OS waking vector.

Average timer value of all resume cycles logged since the last full boot sequence, including the most recent resume. Note that the entire log of timer values does not need to be retained in order to calculate this average. The bit physical address at which the Counter Control block is located.

This value is optional if the system implements EL3 Security Extensions. This value is optional, as an operating system executing in the non-secure world EL2 or EL1 , will ignore the content of these fields. Flags for the secure EL1 timer defined below. This value is optional, as an operating system executing in the non-secure world EL2 or EL1 will ignore the content of this field. The bit physical address at which the Counter Read block is located.

This field is mandatory for systems implementing ARMv8. For systems not implementing ARMv8. Flags for the virtual EL2 timer defined below.

Array of Platform Timer Type structures describing memory-mapped Timers available on this platform. These structures are described in the sections below.

These timers are in addition to the per-processor timers described above them in the GTDT. The first byte of each structure declares the type of that structure and the second and third bytes declare the length of that structure.

The GT Block is a standard timer block that is mapped into the system address space. Flags for the GTx physical timer. Flags for the GTx virtual timer, if implemented. Interleave Structure s see Section 5. Flush Hint Address Structure s see Section 5. Platform Capabilities Structure see Section 5.

Opaque cookie value set by platform firmware for OSPM use, to detect changes that may impact the readability of the data. Refer to the UEFI specification for details.

Since interleave is a repeating pattern, this structure only describes the lines involved in the memory interleave before the pattern start to repeat. Index must be non-zero. Line SPA is naturally aligned to the Line size. Length in bytes for entire structure. The length of this structure is either 32 bytes or 80 bytes. The length of the structure can be 32 bytes only if the Number of Block Control Windows field has a value of 0. Byte 1 of this field is reserved.

Identifier for the NVDIMM non-volatile memory subsystem controller, assigned by the non-volatile memory subsystem controller vendor. Revision of the NVDIMM non-volatile memory subsystem controller, assigned by the non-volatile memory subsystem controller vendor. SPD byte Validity of this field is indicated in Valid Fields Bit [0].

Fields that follow this field are valid only if the number of Block Control Windows is non-zero. In Bytes. Logical offset.

Refer to Note. Logical offset in bytes. Refer to Note1. Bit [0] set to 1 to indicate that the Block Data Windows implementation is buffered. The content of the data window is only valid when so indicated by Status Register.

The logical offset is with respect to the device, not with respect to system physical address space. Software should construct the device address space accounting for interleave before applying the block control start offset. Logical offset in bytes see note below. The address of the next block is obtained by adding the value of this field to Size of Block Data Window.

Note that the platform buffers do not include processor cache s! Processors typically include ISA to flush data out of processor caches. Software is allowed to write up to a cache line of data. The content of the data is not relevant to the functioning of the flush hint mechanism. The bit index of the highest valid capability implemented by the platform. The subsequent bits shall not be considered to determine the capabilities supported by the platform.

The table provides a hint as to which devices should be protected by the secure OS. The enforcement of the table is provided by the secure OS and any pre-boot environment preceding it. The table itself does not provide any security guarantees. It is the responsibility of the system manufacturer to ensure that the operating system is configured to enable security features that make use of the SDEV table.

Device is listed in SDEV. This provides a hint that the device should be always protected within the secure OS. For example, the secure OS may require that a device used for user authentication must be protected to guard against tampering by malicious software.

This provides a hint that the device should be initially protected by the secure OS, but it is up to the discretion of the secure OS to allow the device to be handed off to the non-secure OS when requested.

Any OS component that expected the device to be operating in secure mode would not correctly function after the handoff has been completed.

For example, a device may be used for variety of purposes, including user authentication. If the secure OS determines that the necessary components for driving the device are missing, it may release control of the device to the non-secure OS.

In this case, the device cannot be used for secure authentication, but other operations can correctly function. Device not listed in SDEV. For example, the status quo is that no hints are provided. Any OS component that expected the device to be in secure mode would not correctly function. Reserved for future use. For forward compatibility, software skips structures it does not comprehend by skipping the appropriate number of bytes indicated by the Length field. All new device structures must include the Type, Flags, and Length fields as the first 3 fields respectively.

Length of the list of Secure Access Components data. Identification Based Secure Access Component. A minimum of one is required for a secure device. When there are multiple Identification Components present, priority is determined by list order. Memory Based Secure Access Component. For forward compatibility, software skips structures that it does not comprehend by skipping the appropriate number of bytes indicated by the Length field.

All new device structures must include the Type, Flags, and Length fields as the first 3 fields, respectively. Even numbered offsets contain the Device numbers, and odd numbered offsets contain the Function numbers. Each subsequent pair resides on the bus directly behind the bus of the device identified by the previous pair.

The software is expected to use this information as a hint for optimization, or when the system has heterogeneous memory. Memory Proximity Domain Attributes Structure s. Describes attributes of memory proximity domains. Describes the memory access latency and bandwidth information from various memory access initiator proximity domains. The optional access mode and transfer size parameters indicate the conditions under which the Latency and Bandwidth are achieved.

Memory Side Cache Information Structure s. Describes memory side cache information for memory proximity domains if the memory side cache is present and the physical device SMBIOS handle forms the memory side cache. Memory side cache allows to optimize the performance of memory subsystems. When the software accesses an SPA, if it is present in the near memory hit it would be returned to the software, if it is not present in the near memory miss it would access the next level of memory and so on.

The Level n Memory acts as memory side cache to Level n-1 Memory and Level n-1 memory acts as memory side cache for Level n-2 memory and so on. If Non-Volatile memory is cached by memory side cache, then platform is responsible for persisting the modified contents of the memory side cache corresponding to the Non-Volatile memory area on power failure, system crash or other faults.

This structure describes the system physical address SPA range occupied by the memory subsystem and its associativity with processor proximity domain as well as hint for memory usage. Bit [0]: set to 1 to indicate that data in the Proximity Domain for the Attached Initiator field is valid. Bit [1]: Reserved. Previously defined as Memory Proximity Domain field is valid. Deprecated since ACPI 6. Bit [2]: Reserved. Previously defined as Reservation Hint. Bits [] : Reserved. This field is valid only if the memory controller responsible for satisfying the access to memory belonging to the specified memory proximity domain is directly attached to an initiator that belongs to a proximity domain.

Previously defined as the Range Length of the region in bytes. The Entry Base Unit for latency is in picoseconds. The Initiator to Target Proximity Domain matrix entry can have one of the following values:. The lowest latency number represents best performance and the highest bandwidth number represents best performance. The latency and bandwidth numbers represented in this structure correspond to specification rated latency and bandwidth for the platform. The represented latency is determined by aggregating the specification rated latencies of the memory device and the interconnects from initiator to target.

Indicates total number of Proximity Domains that can initiate memory access requests to other proximity domains. Indicates total number of Proximity Domains that can act as target. This is typically the Memory Proximity Domains. Base unit for Matrix Entry Values latency or bandwidth. Base unit for latency in picoseconds. This field shall be non-zero. The Flag field in this table allows read latency, write latency, read bandwidth and write bandwidth as well as Memory Hierarchy levels, minimum transfer size and access attributes.

Hence this structure could be repeated several times, to express all the appropriate combinations of Memory Hierarchy levels, memory and transfer attributes expressed for each level. If multiple structures are present, they may be ordered starting from most- to least-optimal performance. If either latency or bandwidth information is being presented in the HMAT, it is required to be complete with respect to initiator-target pair entries. For example, if read latencies are being included in the SLLBI, then read latencies for all initiator-target pairs must be present.

If some pairs are incalculable, then the read latency dataset must be omitted entirely. It is acceptable to provide only a subset of the possible datasets. For example, it is acceptable to provide read latencies but omit write latencies.

This provides OSPM a complete picture for at least one set of attributes, and it has the choice of keeping that data or discarding it. System memory hierarchy could be constructed to have a large size of low performance far memory and smaller size of high performance near memory. The Memory Side Cache Information Structure describes memory side cache information for a given memory domain.

The software could use this information to effectively place the data in memory to maximize the performance of the system memory that use the memory side cache. Integer that represents the memory proximity domain to which the memory side cache information applies.

Implementation Note: A proximity domain should contain only one set of memory attributes. If memory attributes differ, represent them in different proximity domains. If the Memory Side Cache Information Structure is present, the System Locality Latency and Bandwidth Information Structure shall contain latency and bandwidth information for each memory side cache level.

This is intended as a standard mechanism for the OSPM to notify the platform of a fatal crash e. This table is intended for platforms that provide debug hardware facilities that can capture system info beyond the normal OS crash dump.

Other platforms may allow the debug trigger for capture system state to debug run-time behavioral issues e. When multiple triggers exist, the triggers within each of the two groups, defined by trigger order, will be executed in order.

Note: The mechanism by which this system debug state information is retrieved by the user is platform and vendor specific. This will most likely will require special tools and privileges in order to access and parse the platform debug information captured by this trigger. It also describes per trigger flags.

Each Identifier is 2 bytes. Must provide a minimum of one identifier. Used in fatal crash scenarios: 0: OSPM must initiate trigger before kernel crash dump processing 1: OSPM must initiate trigger at the end of crash dump processing. A platform debug trigger can choose to use any type of PCC subspace. The definition of the shared memory region for a debug trigger will follow the definition of shared memory region associated with the PCC subspace type used for the debug trigger.

For example if a platform debug trigger chooses to use Generic PCC communication subspace Type 0 , then it will use the Generic Communication Channel shared memory region described in Section If a platform debug trigger choose to use a PCC communication subchannel that uses a Generic Communication shared memory region then it will write the debug trigger command in the command field.

The platform can also use the PCC sub channel Type 5 for debug a trigger. A platform debug trigger using PCC Communication sub channel Type 5 will use the shared memory region to share vendor-specific debug information. The following table defines the Type-5 PCC channel shared memory region definition for debug trigger. For example, subspace 3 has the signature 0x Vendor specific area to share additional information between OSPM and platform.

The length of the vendor specified area must be 4 bytes less than the Length field specified in the PCCT entry referring to this shared memory space. PCC command field, see Section 14 and Table 5. PCC status field see Section Trigger Order 1: Triggers are invoked by OSPM at the end of crash dump processing functions, typically after the kernel has processed crash dumps. Capturing platform specific debug information from certain IPs would require intrusive mechanism which may limit kernel operations after the operations.

Trigger order allows the platform to define such operations that will be invoked at the end of kernel operations by OSPM. To illustrate how these debug triggers are intended to be used by the OS, consider this example of a system with 4 independent debug triggers as shown in Fig. Note: This example assumes no vendor specific communication is required, so only PCC command 0x0 is used.

When the OS encounters a fatal crash, prior to collecting a crash dump and rebooting the system, the OS may choose to invoke the debug triggers in the order listed in the PDTT.

Describing the 4 triggers illustrated in Fig. Since OS must wait for completion, OS must write PCC command 0x0 and write to the doorbell register per section 14 and poll for the completion bit. When wait for completion is necessary, the OS must poll bit zero completion bit of the status field of that PCC channel see Table This optional table is used to describe the topological structure of processors controlled by the OSPM, and their shared resources, such as caches.

The table can also describe additional information such as which nodes in the processor topology constitute a physical package.

The processor hierarchy node structure is described in Table 5. This structure can be used to describe a single processor or a group. To describe topological relationships, each processor hierarchy node structure can point to a parent processor hierarchy node structure.

This allows representing tree like topology structures. Multiple trees may be described, covering for example multiple packages. For the root of a tree, the parent pointer should be 0. If PPTT is present, one instance of this structure must be present for every individual processor presented through the MADT interrupt controller structures. In addition, an individual entry must be present for every instance of a group of processors that shares a common resource described in the PPTT.

Each physical package in the system must also be represented by a processor node structure. Each processor node includes a list of resources that are private to that node. For example, an SoC level processor node might contain two references, one pointing to a Level 3 cache resource and another pointing to an ID structure. For compactness, separate instances of an identical resource can be represented with a single structure that is listed as a resource of multiple processor nodes.

For example, is expected that in the common case all processors will have identical L1 caches. For these platforms a single L1 cache structure could be listed by all processors, as shown in the following figure. Note: though less space efficient, it is also acceptable to declare a node for each instance of a resource. In the example above, it would be legal to declare an L1 for each processor. Note: Compaction of identical resources must be avoided if an implementation requires any resource instance to be referenced uniquely.

For example, in the above example, the L1 resource of each processor must be declared using a dedicated structure to permit unique references to it. Reference to parent processor hierarchy node structure. The reference is encoded as the difference between the start of the PPTT table and the start of the parent processor structure entry. A value of zero must be used where a node has no parent. If the processor structure represents a group of associated processors, the structure might match a processor container in the name space.

Where there is a match it must be represented. Each resource is a reference to another PPTT structure. The structure referred to must not be a processor hierarchy node.

Each resource structure pointed to represents resources that are private the processor hierarchy node. For example, for cache resources, the cache type structure represents caches that are private to the instance of processor topology represented by this processor hierarchy node structure. The references are encoded as the difference between the start of the PPTT table and the start of the resource structure entry. Set to 1 if this node of the processor topology represents the boundary of a physical package, whether socketed or surface mounted.

Set to 0 if this instance of the processor topology does not represent the boundary of a physical package. Each valid processor must belong to exactly one package. That is, the leaf must itself be a physical package or have an ancestor marked as a physical package.

For leaf entries: must be set to 1 if the processing element representing this processor shares functional units with sibling nodes. For non-leaf entries: must be set to 0. A value of 1 indicates that all children processors share an identical implementation revision. This field should be ignored on leaf nodes by the OSPM. Note: this implies an identical processor version and identical implementation reversion, not just a matching architecture revision.

Threads sharing a core must be grouped under a unique Processor hierarchy node structure for each group of threads. Processors may be marked as disabled in the MADT. In this case, the corresponding processor hierarchy node structures in PPTT should be considered as disabled.

Additionally, all processor hierarchy node structures representing a group of processors with all child processors disabled should be considered as being disabled. All resources attached to disabled processor hierarchy node structures in PPTT should also be considered disabled. The cache type structure is described in Table 5.

The cache type structure can be used to represent a set of caches that are private to a particular processor hierarchy node structure, that is, to a particular node in the processor topology tree.

The set of caches is described as a NULL, or zero, terminated linked list. Only the head of the list needs to be listed as a resource by a processor node and counted toward Number of Private Resources , as the cache node itself contains a link to the next level of cache.

Cache type structures are optional, and can be used to complement or replace cache discovery mechanisms provided by the processor architecture. For example, some processor architectures describe individual cache properties, but do not provide ways of discovering which processors share a particular cache.

When cache structures are provided, all processor caches must be described in a cache type structure. Each cache type structure includes a reference to the cache type structure that represents the next level cache. The list must include all caches that are private to a processor hierarchy node. It is not permissible to skip levels. That is, a cache node included in a given hierarchy processor node level must not point to a cache structure referred to by a processor node in a different level of the hierarcy.

Processors, or higher level nodes within the hierarchy, with separate instruction and data caches must describe the instruction and data caches with separate linked lists of cache type structures both listed as private resources of the relevant processor hierarchy node structure. If the separate instruction are data caches are unified at a higher level of cache then the linked lists should converge. Each processor has private L1 data, L1 intruction and L2 caches.

The two processors are contained in a cluster which provides an L3 cache. The resulting list denotes all private caches at the processor level. The L3 node in turn has no next level of cache.

An entry in the list indicates primarily that a cache exists at this node in the hierarchy. Where possible, cache properties should be discovered using processor architectural mechanisms, but the cache type structure may also provide the properties of the cache.

A flag is provided to indicate whether properties provided in the table are valid, in which case the table content should be used in preference to processor architected discovery. On Arm-based systems, all cache properties must be provided in the table.

Reference to next level of cache that is private to the processor topology instance. The reference is encoded as the difference between the start of the PPTT table and the start of the cache type structure entry. This value will be zero if this entry represents the last cache level appropriate to the the processor hierarchy node structures using this entry. Unique, non-zero identifier for this cache. If Cache ID is valid as indicated by the Flags field, then this structure defines a unique cache in the system.

Set to 1 if the size properties described is valid.

This section describes the format of the Platform Health Assessment Table PHAT , which provides a means by which a platform can expose an extensible set of platform health related telemetry that may be useful for software running within the constraints of an operating system. These elements are typically going to encompass things that are likely otherwise not enumerable during the OS runtime phase of operations, such as version of pre-OS components, or health status of firmware drivers that were executed by the platform prior to launch of the OS.

It is not expected that the OSPM would act on the data being exposed.

Xen Project. OSPM examines each table for a known signature. Based on the signature, OSPM can then interpret the implementation-specific data within the table.

Length, in bytes, of the entire RSDT. The length implies the number of Entry fields n at the end of the table. Length, in bytes, of the entire table. All fields in the FADT that provide hardware addresses provide processor-relative physical addresses. In this case, the bit field must be ignored regardless of whether or not it is zero, and whether or not it is the same value as the bit field.

The bit field should only be used if the corresponding bit field contains a zero value, or if the bit value can not be used by the OSPM subject to e.

CPU addressing limitations. This signature predates ACPI 1. See Section 5. Physical memory address of the DSDT. ACPI 1. Platforms should set this field to zero but field values of one are also allowed to maintain compatibility with ACPI 1. System vector the SCI interrupt is wired to in mode. On systems that do not contain the , this field contains the Global System interrupt number of the SCI interrupt.

This field is reserved and must be zero on system that does not support System Management mode. This field is reserved and must be zero on systems that do not support Legacy Mode. The S4BIOS state provides an alternate way to enter the S4 state where the firmware saves and restores the memory context. See Section 4. This is a required field. This field is optional; if this register block is not supported, this field contains zero. See Table 4. See the Section 4. This is an optional field; if this register block is not supported, this field contains zero.

If this register block is not supported, this field contains zero. Support for the PM2 register block is optional. If not supported, this field contains zero.

The worst-case hardware latency, in microseconds, to enter and exit a C2 state. The worst-case hardware latency, in microseconds, to enter and exit a C3 state.

This value is typically at least 2 times the cache size. This field is maintained for ACPI 1. If this field contains a zero, then the RTC day of the month alarm feature is not supported. If this field contains a zero, then the RTC month of the year alarm feature is not supported.

If this field contains a zero, then the RTC centenary feature is not supported. See Table 5. Fixed feature flags. Extended physical address of the FACS. Extended physical address of the DSDT. The address of the Sleep status register, represented in Generic Address Structure format see Section 4.

All bytes in this field are considered part of the vendor identity. These identifiers are defined independently by the vendors themselves, usually following the name of the hypervisor product.

A zero indicates the power button is handled as a fixed feature programming model; a one indicates the power button is handled as a control method device. Independent of the value of this field, the presence of a power button device in the namespace indicates to OSPM that the power button is handled as a control method device.

A zero indicates the sleep button is handled as a fixed feature programming model; a one indicates the sleep button is handled as a control method device. Independent of the value of this field, the presence of a sleep button device in the namespace indicates to OSPM that the sleep button is handled as a control method device. A zero indicates the RTC wake status is supported in fixed register space; a one indicates the RTC wake status is not supported in fixed register space.

Indicates whether the RTC alarm function can wake the system from the S4 state. The RTC alarm can optionally support waking the system from the S4 state, as indicated by this value. A zero indicates that the system cannot support docking. A one indicates that the system can support docking. Notice that this flag does not indicate whether or not a docking station is currently present; it only indicates that the system is capable of docking. System Type Attribute. If set indicates that the system has no internal expansion capabilities and the case is sealed.

A value of one indicates that OSPM should use a platform provided timer to drive any monotonically non-decreasing counters, such as OSPM performance counter services. A value of one indicates that the platform is known to have a correctly implemented ACPI power management timer. A platform may choose to set this flag if a internal processor clock or clocks in a multi-processor configuration cannot provide consistent monotonically non-decreasing counters.

Note: If a value of zero is present, OSPM may arbitrarily choose to use an internal processor clock or a platform timer clock for these operations.

That is, a zero does not imply that OSPM will necessarily use the internal processor clock to generate a monotonically non-decreasing counter to the system. Some existing systems do not reliably set this input today, and this bit allows OSPM to differentiate correctly functioning platforms from platforms with this errata. A one indicates that the platform is compatible with remote power- on. Some existing platforms do not reliably transition to S5 with wake events enabled for example, the platform may immediately generate a spurious wake event after completing the S5 transition.

This flag allows OSPM to differentiate correctly functioning platforms from platforms with this type of errata. A one indicates that all local APICs must be configured for the cluster destination model when delivering interrupts in logical mode. A one indicates that all local xAPICs must be configured for physical destination mode. If this bit is set, interrupt delivery operation in logical destination mode is undefined. A one informs OSPM that the platform is able to achieve power savings in S0 similar to or better than those typically achieved in S3.

In effect, when this bit is set it indicates that the system will achieve no power benefit by making a sleep transition to S3. Most often contains one processor.

Must be connected to AC power to function. This device is used to perform work that is considered mainstream corporate or home computing for example, word processing, Internet browsing, spreadsheets, and so on. A single-user, full-featured, portable computing device that is capable of running on batteries or other power storage devices to perform its normal functions.

This device performs the same task set as a desktop. Often contains more than one processor. A multi-user, stationary computing device that frequently resides in a separate, often specially designed, room. Will almost always contain more than one processor. This device is used to support large-scale networking, database, communications, or financial operations within a corporation or government.

A multi-user, stationary computing device that frequently resides in a separate area or room in a small or home office. May contain more than one processor. This device is generally used to support all of the networking, database, communications, and financial operations of a small office or home office. A multi-user stationary computing device that frequently resides in a separate, often specially designed room. Will often contain more than one processor. This device is used in an environment where power savings features are willing to be sacrificed for better performance and quicker responsiveness.

This device performs many of the same tasks as Mobile; however battery life expectations of Tablet devices generally require more aggressive power savings especially for managing display and touch components.

These flags are used by an OS at boot time before the OS is capable of providing an operating environment suitable for parsing the ACPI namespace to determine the code paths to take during boot. For example, if there are no ISA devices, an OS could skip code that assumes the presence of these devices and their associated resources. These flags are used independently of the ACPI namespace. On other system architectures, the entire field should be set to 0.

User-visible devices are devices that have end-user accessible connectors for example, LPT port , or devices for which the OS must load a device driver so that an end-user application can use a device.

If clear, the OS may assume there are no such devices and that all devices in the system can be detected exclusively via industry standard device enumeration mechanisms including the ACPI namespace.

If set, indicates that the motherboard contains support for a port 60 and 64 based keyboard controller, usually implemented as an or equivalent micro-controller.

For IA 32 and x64 platforms, platform firmware is required to support a 32 bit execution environment. Platform firmware can additionally support a 64 bit execution environment. Otherwise, the platform firmware creates a 32 bit execution environment. IF set to 0 Long mode enabled Paging mode is enabled and physical memory for waking vector is identity mapped virtual address equals physical address Waking vector must be contained within one physical page Selectors are set to be flat and are otherwise not used For 32 bit execution environment: Interrupts must be disabled EFLAGS.

OSPM enabled firmware control structure flags. Platform firmware must initialize this field to zero. Indicates that the platform firmware supports a 64 bit execution environment for the waking vector. Note: this is not a pointer to the Global Lock, it is the actual memory location of the lock.

By convention, this lock is used to ensure that while one environment is accessing some hardware, the other environment is not. When releasing the lock, if the pending bit in the lock is set after the lock is released, a signal is sent via an interrupt mechanism to the other environment to inform it that the lock has been released.

Although using the Global Lock allows various hardware resources to be shared, it is important to notice that its usage when there is ownership contention could entail a significant amount of system overhead as well as waits of an indeterminate amount of time to acquire ownership of the Global Lock. For this reason, implementations should try to design the hardware to keep the required usage of the Global Lock to a minimum.

The Global Lock is required whenever a logical register in the hardware is shared. Similarly if the entire register is shared, as the case might be for the embedded controller interface, access to the register needs to be protected under the Global Lock.

The AML operators defined in this specification are intended to allow many useful hardware designs to be easily expressed, not to allow all hardware designs to be expressed.

A Revision field value greater than or equal to 2 signifies that integers declared within the Definition Block are to be evaluated as bit values.

The ACPI interrupt model describes all interrupts for the entire system in a uniform interrupt model implementation. The choice of the interrupt model s to support is up to the platform designer. The interrupt model cannot be dynamically changed by the system firmware; OSPM will choose which model to use and install support for that model at the time of installation. If a platform supports multiple models, an OS will install support for only one of the models; it will not mix models. Multi-boot capability is a feature in many modern operating systems.

This list will contain all of the structures from Interrupt Controller Structure Types needed to support this platform. These structures are described in the following sections.

A one indicates that the system also has a PC-AT-compatible dual setup. Immediately after the Flags value in the MADT is a list of interrupt controller structures that declare the interrupt features of the machine. The first byte of each structure declares the type of that structure and the second byte declares the length of that structure.

OSPM implementations may limit the number of supported processors on multi-processor platforms. OSPM executes on the boot processor to initialize the platform including other processors.

See the following table Table 5. If this bit is set the processor is ready for use. If this bit is clear and the Online Capable bit is set, system hardware supports enabling this processor during OS runtime. The information conveyed by this bit depends on the value of the Enabled bit. If the Enabled bit is set, this bit is reserved and must be zero. Otherwise, if this this bit is set, system hardware supports enabling this processor during OS runtime.

For more information on global system interrupts see Section 5. When OSPM supports the model, it will assume that all interrupt descriptors reporting global system interrupts correspond to IRQs. In the model all global system interrupts greater than 15 are ignored. For more information on hardware resource configuration see Section 6. Most existing APIC designs, however, will contain at least one exception to this assumption.

The Interrupt Source Override Structure is provided in order to describe these exceptions. Only those that are not identity-mapped onto the APIC interrupt inputs need be described. Interrupt Source Overrides are also necessary when an identity mapped interrupt input has a non-standard polarity. Any source that is non-maskable will not be available for use by devices.

A value of 0xFF signifies that this applies to all processors in the machine. The Global System Interrupt Base field remains unchanged but has been moved. A new address and reserved field have been added. The use of the Processor statement is deprecated. If a platform can generate an interrupt after correcting platform errors e. Some systems may restrict the retrieval of corrected platform error information to a specific processor. In such cases, the firmware indicates the processor that can retrieve the corrected platform error information through the Processor ID and EID fields in the structure below.

If it is not supported by the implementation, then this field must be zero. If the platform is not presenting a GICv2 with virtualization extensions this field can be 0.

Describes the relative power efficiency of the associated processor. Lower efficiency class numbers are more efficient than higher ones e. This interrupt is a level triggered PPI. Zero if SPE is not supported by this processor. If zero, this processor is unusable, and the operating system support will not attempt to use it.

This structure must only be used to describe non-secure MSI frames. SPI Count used by this frame. SPI Base used by this frame. GICR structures should only be used when describing GIC implementations which conform to version 3 or higher of the GIC architecture and which place all Redistributors in the always-on power domain.
