_PLD (Physical Location of Device) returns a bit-packed buffer that is difficult to parse. This change adds a new interface, AcpiDecodePldBuffer that parses the buffer into a more usable local struct. Also adds macros to both get and set individual fields within the packed _PLD buffer. Adds a new include file, acbuffer.h - which will be expanded to add structs for other ACPI names that return buffers. ACPICA BZ 954. Emit (in comments) the decoded contents of a static _PLD buffer in order to improve comprehension of this bit-packed buffer. Add multi-endian support to the _PLD decode routine. Deploy the multi-endian macros to extract data from the _PLD buffer.

This patch supports the upcomming Intel IOMMU hardware a.k.a. Intel(R) Virtualization Technology for Directed I/O Architecture and the hardware spec for the same can be found here http://www.intel.com/technology/virtualization/index.htm FAQ! (questions from akpm, answers from ak) > So... what's all this code for? > > I assume that the intent here is to speed things up under Xen, etc? Yes in some cases, but not this code. That would be the Xen version of this code that could potentially assign whole devices to guests. I expect this to be only useful in some special cases though because most hardware is not virtualizable and you typically want an own instance for each guest. Ok at some point KVM might implement this too; i likely would use this code for this. > Do we > have any benchmark results to help us to decide whether a merge would be > justified? The main advantage for doing it in the normal kernel is not performance, but more safety. Broken devices won't be able to corrupt memory by doing random DMA. Unfortunately that doesn't work for graphics yet, for that need user space interfaces for the X server are needed. There are some potential performance benefits too: - When you have a device that cannot address the complete address range an IOMMU can remap its memory instead of bounce buffering. Remapping is likely cheaper than copying. - The IOMMU can merge sg lists into a single virtual block. This could potentially speed up SG IO when the device is slow walking SG lists. [I long ago benchmarked 5% on some block benchmark with an old MPT Fusion; but it probably depends a lot on the HBA] And you get better driver debugging because unexpected memory accesses from the devices will cause a trappable event. > > Does it slow anything down? It adds more overhead to each IO so yes. This patch: Add support for early detection and parsing of DMAR's (DMA Remapping) reported to OS via ACPI tables. DMA remapping(DMAR) devices support enables independent address translations for Direct Memory Access(DMA) from Devices. These DMA remapping devices are reported via ACPI tables and includes pci device scope covered by these DMA remapping device.

The Table Manager component has been completely redesigned and reimplemented. The new design is much simpler, and reduces the overall code and data size of the kernel-resident ACPICA by approximately 5%. Also, it is now possible to obtain the ACPI tables very early during kernel initialization, even before dynamic memory management is initialized.

Implemented header file support for the following additional ACPI tables: ASF!, BOOT, CPEP, DBGP, MCFG, SPCR, SPMI, TCPA, and WDRT. With this support, all current and known ACPI tables are now defined in the ACPICA headers and are available for use by device drivers and other software. Implemented support to allow tables that contain ACPI names with invalid characters to be loaded. Previously, this would cause the table load to fail, but since there are several known cases of such tables on existing machines, this change was made to enable ACPI support for them. Also, this matches the behavior of the Microsoft ACPI implementation. https://bugzilla.novell.com/show_bug.cgi?id=147621 Fixed a couple regressions introduced during the memory optimization in the 20060317 release. The namespace node definition required additional reorganization and an internal datatype that had been changed to 8-bit was restored to 32-bit. (Valery Podrezov) Fixed a problem where a null pointer passed to acpi_ut_delete_generic_state() could be passed through to acpi_os_release_object which is unexpected. Such null pointers are now trapped and ignored, matching the behavior of the previous implementation before the deployment of acpi_os_release_object(). (Valery Podrezov, Fiodor Suietov) Fixed a memory mapping leak during the deletion of a SystemMemory operation region where a cached memory mapping was not deleted. This became a noticeable problem for operation regions that are defined within frequently used control methods. (Dana Meyers) Reorganized the ACPI table header files into two main files: one for the ACPI tables consumed by the ACPICA core, and another for the miscellaneous ACPI tables that are consumed by the drivers and other software. The various FADT definitions were merged into one common section and three different tables (ACPI 1.0, 1.0+, and 2.0) Signed-off-by: NBob Moore <robert.moore@intel.com> Signed-off-by: NLen Brown <len.brown@intel.com>

Added 2006 copyright. At SuSE's suggestion, enabled all error messages without enabling function tracing, ie with CONFIG_ACPI_DEBUG=n Replaced all instances of the ACPI_DEBUG_PRINT macro invoked at the ACPI_DB_ERROR and ACPI_DB_WARN debug levels with the ACPI_REPORT_ERROR and ACPI_REPORT_WARNING macros, respectively. This preserves all error and warning messages in the non-debug version of the ACPICA code (this has been referred to as the "debug lite" option.) Over 200 cases were converted to create a total of over 380 error/warning messages across the ACPICA code. This increases the code and data size of the default non-debug version by about 13K. Added ACPI_NO_ERROR_MESSAGES flag to enable deleting all messages. The size of the debug version remains about the same.

The use of the CPU stack in the debug version of the subsystem has been considerably reduced. Previously, a debug structure was declared in every function that used the debug macros. This structure has been removed in favor of declaring the individual elements as parameters to the debug functions. This reduces the cumulative stack use during nested execution of ACPI function calls at the cost of a small increase in the code size of the debug version of the subsystem. With assistance from Alexey Starikovskiy and Len Brown. Added the ACPI_GET_FUNCTION_NAME macro to enable the compiler-dependent headers to define a macro that will return the current function name at runtime (such as __FUNCTION__ or _func_, etc.) The function name is used by the debug trace output. If ACPI_GET_FUNCTION_NAME is not defined in the compiler-dependent header, the function name is saved on the CPU stack (one pointer per function.) This mechanism is used because apparently there exists no standard ANSI-C defined macro that that returns the function name. Alexey Starikovskiy redesigned and reimplemented the "Owner ID" mechanism used to track namespace objects created/deleted by ACPI tables and control method execution. A bitmap is now used to allocate and free the IDs, thus solving the wraparound problem present in the previous implementation. The size of the namespace node descriptor was reduced by 2 bytes as a result. Removed the UINT32_BIT and UINT16_BIT types that were used for the bitfield flag definitions within the headers for the predefined ACPI tables. These have been replaced by UINT8_BIT in order to increase the code portability of the subsystem. If the use of UINT8 remains a problem, we may be forced to eliminate bitfields entirely because of a lack of portability. Alexey Starikovksiy enhanced the performance of acpi_ut_update_object_reference. This is a frequently used function and this improvement increases the performance of the entire subsystem. Alexey Starikovskiy fixed several possible memory leaks and the inverse - premature object deletion. Signed-off-by: NLen Brown <len.brown@intel.com>

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
