[RFC PATCH 0/3] ECAM quirks handling for ARM64 platforms

by Tomasz Nowicki

This series bases on pending ACPI PCI support for ARM64: https://lkml.org/lkml/2016/5/30/468 Quirk handling relies on an idea of matching MCFG OEM ID and OEM revision (the ones from standard header of MCFG table). Linker section is used so that quirks can be registered using special macro (see patches) and kept self contained. As an example, last patch presents above mechanism usage for ThunderX PEM driver. Tomasz Nowicki (3): pci, acpi: Match PCI config space accessors against platfrom specific ECAM quirks. arm64, pci: Start using quirks handling for ACPI based PCI host controller. pci, pci-thunder-pem: Add ACPI support for ThunderX PEM. arch/arm64/kernel/pci.c | 7 +- drivers/acpi/pci_mcfg.c | 32 +++++++++ drivers/pci/host/pci-thunder-pem.c | 132 +++++++++++++++++++++++++++++++++---- include/asm-generic/vmlinux.lds.h | 7 ++ include/linux/pci-acpi.h | 19 ++++++ 5 files changed, 181 insertions(+), 16 deletions(-) -- 1.9.1

[PATCH v7 0/9] 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/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. Also add add the ARM64-specific ACPI Support maintainers in MAINTAINERS. (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: v7: 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). Fix the bug about the config problem, use CONFIG_ACPI_GTDT instead of CONFIG_ACPI in arm_arch_timer.c v1: The first upstreaming version: https://lkml.org/lkml/2015/10/28/553 Fu Wei (9): clocksource/drivers/arm_arch_timer: Move enums and defines to header file clocksource/drivers/arm_arch_timer: Add a new enum for spi type clocksource/drivers/arm_arch_timer: Improve printk relevant code acpi/arm64: Add GTDT table parse driver MAINTAINERS / ACPI: add the ARM64-specific ACPI Support maintainers clocksource/drivers/arm_arch_timer: Simplify ACPI support code. acpi/arm64: Add memory-mapped timer support in GTDT driver clocksource/drivers/arm_arch_timer: Add GTDT support for memory-mapped timer acpi/arm64: Add SBSA Generic Watchdog support in GTDT driver MAINTAINERS | 8 + drivers/acpi/Kconfig | 5 + drivers/acpi/Makefile | 1 + drivers/acpi/arm64/Kconfig | 15 ++ drivers/acpi/arm64/Makefile | 1 + drivers/acpi/arm64/acpi_gtdt.c | 343 +++++++++++++++++++++++++++++++++++ drivers/clocksource/Kconfig | 1 + drivers/clocksource/arm_arch_timer.c | 228 ++++++++++++++++------- drivers/watchdog/Kconfig | 1 + include/clocksource/arm_arch_timer.h | 32 ++++ include/linux/acpi.h | 7 + 11 files changed, 575 insertions(+), 67 deletions(-) create mode 100644 drivers/acpi/arm64/Kconfig create mode 100644 drivers/acpi/arm64/Makefile create mode 100644 drivers/acpi/arm64/acpi_gtdt.c -- 2.5.5

[PATCH 0/3] watchdog, sbsa_gwdt: Update SBSA watchdog with the new infrastructure of watchdog.

by fu.wei＠linaro.org

From: Fu Wei <fu.wei(a)linaro.org> This patchset: (1)Try to fix an issue about min and max timeout validity check: when max_hw_heartbeat_ms is defined, this check should be skipped. (2)Use max_hw_heartbeat_ms instead of max_timeout in SBSA watchdog. (3)Set WDOG_HW_RUNNING, when SBSA watchdog is already running before it's initialized. Changelog: v1: The first formal upstreaming version RFC: https://lkml.org/lkml/2016/5/3/145 Pratyush Anand (3): watchdog: skip min and max timeout validity check when max_hw_heartbeat_ms is defined sbsa_gwdt: Use max_hw_heartbeat_ms instead of max_timeout sbsa_gwdt: Set WDOG_HW_RUNNING, when watchdog is already running. drivers/watchdog/sbsa_gwdt.c | 6 ++++-- drivers/watchdog/watchdog_core.c | 2 +- 2 files changed, 5 insertions(+), 3 deletions(-) -- 2.5.5
