by Tomasz Nowicki

Patch set implement as follows: 1. Minor changes around existing tools - reorganize building process, - move common code to separate direction, - no functionality changes. 2. Add BFAPEI (Blob For APEI) tool which can create blobs for APEI testing. - see commit log for more details Changes for v2: - compilation regardless of whether APEI is used or not, - correct file name in comment headers, - move ACPI structures, defines, etc. to acpi.h headers, - suppress compiler warnings. Tomasz Nowicki (4): map, cab: Reorganize building process and tree hierarchy. bfapei: Add tool that can create blobs for APEI table testing. bfapei: Move generic ACPI structures to separated file, remove duplicated defines. Suppress compiler warnings, file comment headers cleanup.

[PATCH v2] EFI: fix build for AARCH64

by Leif Lindholm

AARCH64 build was left out of initial version, so add to .dsc and set ACPI_MACHINE_WIDTH correctly. Also, acpidump.inf specified explicit per-architecture (but identical) CFLAGS. Rather than duplicating this further, use the same setting for all architectures until there is actually a need to diverge. Also update README to make it obvious AArch64 is supported.

[PATCH v2] PCI: Add information about describing PCI in ACPI

by Bjorn Helgaas

Here's another stab at this writeup. I'd appreciate any comments! Changes from v1 to v2: - Consumer/Producer is defined for Extended Address Space descriptors; should be ignored for QWord/DWord/Word Address Space descriptors - New arches may use Extended Address Space descriptors in PNP0A03 for bridge registers, including ECAM (if the arch adds support for this) - Add more details about MCFG and _CBA (Lv's suggestion) - Incorporate Rafael's suggestions --- Bjorn Helgaas (1): PCI: Add information about describing PCI in ACPI Documentation/PCI/00-INDEX | 2 Documentation/PCI/acpi-info.txt | 180 +++++++++++++++++++++++++++++++++++++++ 2 files changed, 182 insertions(+) create mode 100644 Documentation/PCI/acpi-info.txt

[PATCH v20 00/17] acpi, clocksource: add GTDT driver and GTDT support in arm_arch_timer

by fu.wei＠linaro.org

From: Fu Wei <fu.wei(a)linaro.org> This patchset: (1)Preparation for adding GTDT support in arm_arch_timer: 1. Clean up printk() usage 2. Rename the type macros 3. Rename the PPI enum & enum values 4. Move the type macro and PPI enum into the header file 5. Add new enum for SPIs 6. Rework PPI determination; 7. Rework counter frequency detection; 8. Refactor arch_timer_needs_probing, move it into DT init call 9. Introduce some new structs and refactor the MMIO timer init code for reusing some common code. (2)Introduce ACPI GTDT parser: drivers/acpi/arm64/acpi_gtdt.c Parse all kinds of timer in GTDT table of ACPI:arch timer, memory-mapped timer and SBSA Generic Watchdog timer. This driver can help to simplify all the relevant timer drivers, and separate all the ACPI GTDT knowledge from them. (3)Simplify ACPI code for arm_arch_timer (4)Add GTDT support for ARM memory-mapped timer. This patchset has been tested on the following platforms with ACPI enabled: (1)ARM Foundation v8 model Changelog: v20: https://lkml.org/lkml/2017/1/18/ Reorder the first 4 patches and split the 4th patches.

Add "request_mem_region" for ioremapping cntbase, according to f947ee1 clocksource/drivers/arm_arch_timer: Map frame with of_io_request_and_map() Rebase to 4.9.0-gfb779ff v18: https://lkml.org/lkml/2016/12/8/446 Fix 8/15 patch problem of "int ret;" in arch_timer_acpi_init. Rebase to 4.9.0-rc8-g9269898 v17: https://lkml.org/lkml/2016/11/25/140 Take out some cleanups from 4/15. Merge 5/15 and 6/15, improve PPI determination code, improve commit message. Rework counter frequency detection. Move arch_timer_needs_of_probing into DT init call. Move Platform Timer scan loop back to timer init call to avoid allocating and free memory. Improve all the exported functions' comment. v16: https://lkml.org/lkml/2016/11/16/268 Fix patchset problem about static enum ppi_nr of 01/13 in v15. Refactor arch_timer_detect_rate. Refactor arch_timer_needs_probing. v15: https://lkml.org/lkml/2016/11/15/366 Re-order patches Add arm_arch_timer refactoring patches to prepare for GTDT: 1. rename some enums and defines, and some cleanups 2. separate out arch_timer_uses_ppi init code and fix a potential bug 3. Improve some new structs, refactor the timer init code. Since the some structs have been changed, GTDT parser for memory-mapped timer and SBSA Generic Watchdog timer have been update. v14: https://lkml.org/lkml/2016/9/28/573 Separate memory-mapped timer GTDT support into two patches 1.

[PATCH v18 00/15] acpi, clocksource: add GTDT driver and GTDT support in arm_arch_timer

by fu.wei＠linaro.org

From: Fu Wei <fu.wei(a)linaro.org> This patchset: (1)Preparation for adding GTDT support in arm_arch_timer: 1. Move some enums and marcos to header file; 2. Add a new enum for spi type; 3. Improve printk relevant code; 4. Rename some enums and defines; 5. Rework PPI determination; 6. Rework counter frequency detection; 7. Refactor arch_timer_needs_probing, move it into DT init call 8. Introduce some new structs and refactor the MMIO timer init code for reusing some common code. (2)Introduce ACPI GTDT parser: drivers/acpi/arm64/acpi_gtdt.c Parse all kinds of timer in GTDT table of ACPI:arch timer, memory-mapped timer and SBSA Generic Watchdog timer. This driver can help to simplify all the relevant timer drivers, and separate all the ACPI GTDT knowledge from them. (3)Simplify ACPI code for arm_arch_timer (4)Add GTDT support for ARM memory-mapped timer. This patchset has been tested on the following platforms with ACPI enabled: (1)ARM Foundation v8 model Changelog: v18: https://lkml.org/lkml/2016/12/8/ Fix 8/15 patch problem of "int ret;" in arch_timer_acpi_init Rebase to 4.9.0-rc8-g9269898 v17: https://lkml.org/lkml/2016/11/25/140 Take out some cleanups from 4/15.
