[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 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. Any help in reviewing and testing is very appreciated. v8 -> v9 - additional cleanups around generic assignment - added back MCFG entries cache - simplified config start address lookup - fixed leak in pci_acpi_scan_root() - isolated patch with ACPI RAW accessors implementation - rebase against 4.7-rc2 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 - rebase against 4.7-rc1 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 v7 - https://lkml.org/lkml/2016/5/10/568 v8 - https://lkml.org/lkml/2016/5/30/468 Jayachandran C (3): PCI/ECAM: Move ecam.h to linux/include/pci-ecam.h PCI/ECAM: Add parent device field to pci_config_window ACPI/PCI: Support IO resources when parsing PCI host bridge resources Sinan Kaya (1): PCI: Add new function to unmap IO resources Tomasz Nowicki (7): ACPI/PCI: Add generic MCFG table handling PCI: Refactor generic bus domain assignment PCI: Factor DT specific pci_bus_find_domain_nr() code out ARM64/PCI: Add ACPI hook to assign domain number ARM64/PCI: ACPI support for legacy IRQs parsing and consolidation with DT code ARM64/PCI: Implement ACPI low-level calls to access PCI_Config region from AML ARM64/PCI: Support for ACPI based PCI host controller arch/arm64/Kconfig | 2 + arch/arm64/kernel/pci.c | 146 ++++++++++++++++++++++++++++++++++-- drivers/acpi/Kconfig | 3 + drivers/acpi/Makefile | 1 + drivers/acpi/pci_mcfg.c | 92 +++++++++++++++++++++++ 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 ++++++- drivers/pci/probe.c | 4 +- include/linux/pci-acpi.h | 2 + include/linux/pci-ecam.h | 67 +++++++++++++++++ include/linux/pci.h | 15 ++-- 17 files changed, 392 insertions(+), 96 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 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).

[PATCH v9 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; 4. use readq to get 64-bit CNTVCT. (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: V9: https://lkml.org/lkml/2016/7/25/ Improve pr_err message in acpi gtdt driver.

[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.
