[RFC PATCH V2 0/2] ECAM quirks handling for ARM64 platforms

by Dongdong Liu

This series bases on pending ACPI PCI support for ARM64: https://lkml.org/lkml/2016/6/10/706 Quirk handling relies on an idea of matching MCFG OEM ID and OEM TABLE ID (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. v1 -> v2 - use oem_id and oem_table_id to replace oem_id and oem_revision to make a difference between different platforms. - change pci_cfg_fixup __mcfg_fixup_##system##dom##bus to __mcfg_fixup_##oem_id##oem_table_id##dom##bus. With oem_id and oem_table_id is to ensure that the object is unique.

[RESEND PATCH v5 0/1] ARM64: ACPI: Update documentation for latest specification version

by Al Stone

This is a resend only: Ping? Last ping was 26 May; there has been zero response since then. Already have one ACK from Lorenzo; another from an arm64 maintainer would be really helpful. The ACPI 6.1 specification was recently released at the end of January 2016, but the arm64 kernel documentation for the use of ACPI was written for the 5.1 version of the spec. There were significant additions to the spec that had not yet been mentioned -- for example, the 6.0 mechanisms added to make it easier to define processors and low power idle states, as well as the 6.1 addition allowing regular interrupts (not just from GPIO) be used to signal ACPI general purpose events. This patch reflects going back through and examining the specs in detail and updating content appropriately. Whilst there, a few odds and ends of typos were caught as well. This brings the documentation up to date with ACPI 6.1 for arm64. Changes for v5: -- Miscellaneous typos and corrections (Lorenzo Pieralisi) -- Add linux-acpi@ ML to the distribution list (Alexey Klimov) -- Corrections to CPPC information (Alexey Klimov) -- ACK from Lorenzo Pieralisi -- Updated bibliographic info (Al Stone) Changes for v4: -- Clarify that IORT can sometimes be optional (Jon Masters). -- Remove "Use as needed" descriptions of ACPI objects; they provide no substantive information and doing so simplifies maintenance of this document over time. These have been replaced with a simpler notice that states that unless otherwise noted, do what the ACPI specification says is needed. -- Corrected the _OSI object usage recommendation; it described kernel behavior that does not exist (Al Stone). Changes for v3: -- Clarify use of _LPI/_RDI (Vikas Sajjan) -- Whitespace cleanup as pointed out by checkpatch Changes for v2: -- Clean up white space (Harb Abdulhahmid) -- Clarification on _CCA usage (Harb Abdulhamid) -- IORT moved to required from recommended (Hanjun Guo) -- Clarify IORT description (Hanjun Guo) Al Stone (1): ARM64: ACPI: Update documentation for latest specification version Documentation/arm64/acpi_object_usage.txt | 343 ++++++++++++++++-------------- Documentation/arm64/arm-acpi.txt | 40 ++-- 2 files changed, 213 insertions(+), 170 deletions(-) -- 2.5.5

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. (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: v5: 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.
