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.

kernelci.org: infrastructure woes, reducing number of trees

by Kevin Hilman

If you're on the To: line, you have a kernel tree currently being build/boot tested by kernelCI.org that will be disabled (hopefully, temporarily.) Our infrastructure (graciously hosted by Linaro) is having several problems, and is not currently scaling well as we've been adding trees. These issues have been causing a variety of problems, but mainly resulting lots of false failures and generally low quality and usefulness of the reporting. Until we have the time and resources to address these growing pains (kernel CI is currently all-volunteer, spare-time only), we've decided to reduce the number of trees we build to: mainline, linux-next, arm-soc, and stable. This will reduce load and (hopefully) increase the quality of the remaining upstream-focused build/boot results until we have the resources (both time and humans) to address the current problems and make things scalable to a large number of trees. Sorry for the inconvenience, Kevin (on behalf of the core kernel CI team of myself and the Linaro crew: Tyler Baker, Milo Casagrande, Mark Brown and Matt Hart.)

[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.

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.

[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. 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.

[PATCH] 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 V1 0/2] Add support for ThunderX SoCs ACPI Host Controllers

by Tomasz Nowicki

These patches were part of https://lkml.org/lkml/2016/9/9/666 series, however, only core part (first two patches) was approved. ThunderX quirk example had some comments which are address in this series (resetting version numbering). Add ACPI PCI host controler support for ThunderX SoCs pass1.x & pass2.x using ACPI quirk mechanism [1]. Patches rework ThunderX ECAM and PEM driver to work with ACPI & DT boot method. Patch set can be found here: git@github.com:semihalf-nowicki-tomasz/linux.git (pci-quirks-thunderx-v1) It is based on branch pci/ecam-v6 which can be found here: [1] https://git.kernel.org/pub/scm/linux/kernel/git/helgaas/pci.git (pci/ecam-v6) Tomasz Nowicki (2): PCI: thunder: Enable ACPI PCI controller for ThunderX pass2.x silicon version PCI: thunder: Enable ACPI PCI controller for ThunderX pass1.x silicon version drivers/acpi/pci_mcfg.c | 35 ++++++++++++ drivers/pci/host/pci-thunder-ecam.c | 2 +- drivers/pci/host/pci-thunder-pem.c | 107 +++++++++++++++++++++++++++++++----- include/linux/pci-ecam.h | 7 +++ 4 files changed, 136 insertions(+), 15 deletions(-) -- 2.7.4
