[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

[PATCH V8 0/9] 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. Support for generic domain assignment based on ACPI 4. New MCFG driver 5. Implement ARM64 ACPI based PCI host controller driver under arch/arm64/ Patches has been built on top of 4.7-rc1 and can be found here: git@github.com:semihalf-nowicki-tomasz/linux.git (pci-acpi-v8) This has been tested on Cavium ThunderX server. Any help in reviewing and testing is very appreciated. v7 -> v8 - move code from drivers/acpi/pci_root_generic.c to arch/arm64/kernel/pci.c - minor changes around domain assignment - pci_mcfg.c improvements for parsing MCFG tables and lookup its entries v6 -> v7 - drop quirks handling - changes for ACPI companion and domain number assignment approach - implement arch pcibios_{add|remove}_bus and call acpi_pci_{add|remove}_bus from there - cleanups around nomenclature - use resources oriented API for ECAM - fix for based address calculation before mapping ECAM region - remove useless lock for MCFG lookup - move MCFG stuff to separated file pci_mcfg.c - drop MCFG entries caching - rebase against 4.6-rc7 v5 -> v6 - drop idea of x86 MMCONFIG code refactoring - integrate JC's patches which introduce new ECAM API: https://lkml.org/lkml/2016/4/11/907 git: https://github.com/jchandra-brcm/linux/ (arm64-acpi-pci-v3) - integrate Sinan's fix for releasing IO resources, see patch [06/13] - added ACPI support for ThunderX ECAM and PEM drivers - rebase against 4.6-rc2 v4 -> v5 - drop MCFG refactoring group patches 1-6 from series v4 and integrate Jayachandran's patch https://patchwork.ozlabs.org/patch/575525/ - rewrite PCI legacy IRQs allocation - squash two patches 11 and 12 from series v4, fixed bisection issue - changelog improvements - rebase against 4.5-rc3 v3 -> v4 - drop Jiang's fix http://lkml.iu.edu/hypermail/linux/kernel/1601.1/04318.html - add Lorenzo's fix patch 19/24 - ACPI PCI bus domain number assigning cleanup - change resource management, we now claim and reassign resources - improvements for applying quirks - drop Matthew's http://www.spinics.net/lists/linux-pci/msg45950.html dependency - rebase against 4.5-rc1 v2 -> v3 - fix legacy IRQ assigning and IO ports registration - remove reference to arch specific companion device for ia64 - move ACPI PCI host controller driver to pci_root.c - drop generic domain assignment for x86 and ia64 as I am not able to run all necessary test variants - drop patch which cleaned legacy IRQ assignment since it belongs to Mathew's series: https://patchwork.ozlabs.org/patch/557504/ - extend MCFG quirk code - rebase against 4.4 v1 -> v2 - move non-arch specific piece of code to dirver/acpi/ directory - fix IO resource handling - introduce PCI config accessors quirks matching - moved ACPI_COMPANION_SET to generic code v1 - https://lkml.org/lkml/2015/10/27/504 v2 - https://lkml.org/lkml/2015/12/16/246 v3 - http://lkml.iu.edu/hypermail/linux/kernel/1601.1/04308.html v4 - https://lkml.org/lkml/2016/2/4/646 v5 - https://lkml.org/lkml/2016/2/16/426 v6 - https://lkml.org/lkml/2016/4/15/594 Jayachandran C (2): PCI: ecam: move ecam.h to linux/include/pci-ecam.h PCI: ecam: Add parent device field to pci_config_window Tomasz Nowicki (7): pci: Add new function to unmap IO resources. acpi, pci: Support IO resources when parsing PCI host bridge resources. pci, acpi: add acpi hook to assign domain number. arm64, pci, acpi: ACPI support for legacy IRQs parsing and consolidation with DT code. acpi: Add generic MCFG table handling arm64, pci, acpi: Provide ACPI-specific prerequisites for PCI bus enumeration. pci, acpi: ARM64 support for ACPI based generic PCI host controller arch/arm64/Kconfig | 2 + arch/arm64/kernel/pci.c | 143 ++++++++++++++++++++++++++++++++++-- drivers/acpi/Kconfig | 3 + drivers/acpi/Makefile | 1 + drivers/acpi/pci_mcfg.c | 94 ++++++++++++++++++++++++ drivers/acpi/pci_root.c | 39 ++++++++++ drivers/pci/ecam.c | 6 +- drivers/pci/ecam.h | 67 ----------------- drivers/pci/host/pci-host-common.c | 3 +- drivers/pci/host/pci-host-generic.c | 3 +- drivers/pci/host/pci-thunder-ecam.c | 3 +- drivers/pci/host/pci-thunder-pem.c | 6 +- drivers/pci/pci.c | 29 +++++++- include/linux/pci-acpi.h | 2 + include/linux/pci-ecam.h | 67 +++++++++++++++++ include/linux/pci.h | 9 ++- 16 files changed, 387 insertions(+), 90 deletions(-) create mode 100644 drivers/acpi/pci_mcfg.c delete mode 100644 drivers/pci/ecam.h create mode 100644 include/linux/pci-ecam.h -- 1.9.1

[PATCH v5 0/6] 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. (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. 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 (6): 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: Add GTDT table parse driver into ACPI driver clocksource/drivers/arm_arch_timer: Simplify ACPI support code. clocksource/drivers/arm_arch_timer: Add GTDT support for memory-mapped timer drivers/acpi/Kconfig | 9 + drivers/acpi/Makefile | 1 + drivers/acpi/acpi_gtdt.c | 309 +++++++++++++++++++++++++++++++++++ drivers/clocksource/Kconfig | 1 + drivers/clocksource/arm_arch_timer.c | 233 ++++++++++++++++++-------- include/clocksource/arm_arch_timer.h | 33 ++++ include/linux/acpi.h | 6 + 7 files changed, 522 insertions(+), 70 deletions(-) create mode 100644 drivers/acpi/acpi_gtdt.c -- 2.5.5
