[PATCH 0/4 v2] Add tool to enable APEI tables test, other minor changes.

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 v14] acpi, apei, arm64: APEI initial support for aarch64.

[PATCH V9 00/11] Support for ARM64 ACPI based PCI host controller

by Tomasz Nowicki

>From the functionality point of view this series may be split into the following logic parts: 1. Export ECAM API and add parent device to pci_config_window 2. Add IO resources handling to PCI core code 3. New MCFG driver 4. Cleanups and support for generic domain assignment based on ACPI 5. Implement ARM64 ACPI based PCI host controller driver under arch/arm64/ Patches has been built on top of 4.7-rc2 and can be found here: git@github.com:semihalf-nowicki-tomasz/linux.git (pci-acpi-v9) This has been tested on Cavium ThunderX server.

[RFC PATCH V5 0/5] ECAM quirks handling for ARM64 platforms

by Tomasz Nowicki

Quirk handling relies on an idea of matching MCFG OEM ID, TABLE ID and revision (the ones from standard header of MCFG table). Static array is used to keep quirk entries. Each entry consists of mentioned MCFG IDs along with custom pci_ops structure and initialization call. As an example, the last patch presents quirk handling mechanism usage for ThunderX PEM driver. v4 -> v5 - rebase against v4.8-rc1 - rework to exact MCFG OEM ID, TABLE ID, rev match - use memcmp instead of strncmp - no substring match - fix typos and dmesg message Tomasz Nowicki (5): PCI: Embed pci_ecam_ops in pci_config_window structure PCI/ACPI: Move ACPI ECAM mapping to generic MCFG driver PCI: Check platform specific ECAM quirks ARM64/PCI: Start using quirks handling for ACPI based PCI host controller PCI: thunder-pem: Support quirky configuration space access for ACPI based PCI host controller arch/arm64/kernel/pci.c | 42 +---------------- drivers/acpi/pci_mcfg.c | 40 ++++++++++++++++ drivers/pci/ecam.c | 6 +-- drivers/pci/host/Makefile | 1 + drivers/pci/host/mcfg-quirks.c | 93 ++++++++++++++++++++++++++++++++++++ drivers/pci/host/mcfg-quirks.h | 24 ++++++++++ drivers/pci/host/pci-thunder-pem.c | 96 ++++++++++++++++++++++++++++++++------ include/linux/pci-acpi.h | 5 ++ include/linux/pci-ecam.h | 2 +- 9 files changed, 252 insertions(+), 57 deletions(-) create mode 100644 drivers/pci/host/mcfg-quirks.c create mode 100644 drivers/pci/host/mcfg-quirks.h -- 1.9.1

[PATCH v10 0/8] 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. (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: (1)ARM Foundation v8 model Changelog: V10: https://lkml.org/lkml/2016/7/26/ Drop the "readq" patch. Rebase to latest Linux 4.7. V9: https://lkml.org/lkml/2016/7/25/345 Improve pr_err message in acpi gtdt driver. Update Commit message for 7/9 shorten the irq mapping function name Improve GTDT driver for memory-mapped timer v8: https://lkml.org/lkml/2016/7/19/660 Improve "pr_fmt(fmt)" definition: add "ACPI" in front of "GTDT", and also improve printk message. Simplify is_timer_block and is_watchdog. Merge acpi_gtdt_desc_init and gtdt_arch_timer_init into acpi_gtdt_init(); Delete __init in include/linux/acpi.h for GTDT API Make ARM64 select GTDT. Delete "#include <linux/module.h>" from acpi_gtdt.c Simplify GT block parse code. v7: https://lkml.org/lkml/2016/7/13/769 Move the GTDT driver to drivers/acpi/arm64 Add add the ARM64-specific ACPI Support maintainers in MAINTAINERS Merge 3 patches of GTDT parser driver. Fix the for_each_platform_timer bug. v6: https://lkml.org/lkml/2016/6/29/580 split the GTDT driver to 4 parts: basic, arch_timer, memory-mapped timer, and SBSA Generic Watchdog timer Improve driver by suggestions and example code from Daniel Lezcano v5: https://lkml.org/lkml/2016/5/24/356 Sorting out all patches, simplify the API of GTDT driver: GTDT driver just fills the data struct for arm_arch_timer driver. v4: https://lists.linaro.org/pipermail/linaro-acpi/2016-March/006667.html Delete the kvm relevant patches Separate two patches for sorting out the code for arm_arch_timer. Improve irq info export code to allow missing irq info in GTDT table. v3: https://lkml.org/lkml/2016/2/1/658 Improve GTDT driver code: (1)improve pr_* by defining pr_fmt(fmt) (2)simplify gtdt_sbsa_gwdt_init (3)improve gtdt_arch_timer_data_init, if table is NULL, it will try to get GTDT table. Move enum ppi_nr to arm_arch_timer.h, and add enum spi_nr. Add arm_arch_timer get ppi from DT and GTDT support for kvm. v2: https://lkml.org/lkml/2015/12/2/10 Rebase to latest kernel version(4.4-rc3).
