[PATCH V10 0/8] Introduce ACPI world to ITS irqchip

by Tomasz Nowicki

The series builds the PCI/MSI domain stack based on initial IORT driver which is added in first place.

[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.

[PATCH v11] acpi, apei, arm64: APEI initial support for aarch64.

by fu.wei＠linaro.org

From: Tomasz Nowicki <tomasz.nowicki(a)linaro.org> This commit provides APEI arch-specific bits for aarch64 Meanwhile, (1)add a new subfunction "hest_ia32_init" for "acpi_disable_cmcff" which is used by IA-32 Architecture Corrected Machine Check (CMC). (2)move HEST type (ACPI_HEST_TYPE_IA32_CORRECTED_CHECK) checking to a generic place. (3)select HAVE_ACPI_APEI when EFI and ACPI is set on ARM64, because arch_apei_get_mem_attribute is using efi_mem_attributes on ARM64.

[RFC PATCH v4 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 consist of metioned MCFG IDs along with custom pci_ops structure and initialization call. As an example, last patch presents quirk handling mechanism usage for ThunderX PEM driver. 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: Add ThunderX PEM MCFG quirk to the list 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 | 95 +++++++++++++++++++++++++++++++++++++ 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, 254 insertions(+), 57 deletions(-) create mode 100644 drivers/pci/host/mcfg-quirks.c create mode 100644 drivers/pci/host/mcfg-quirks.h -- 1.9.1

[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
