[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 V2 0/4] acpi: cppc optimization patches

by Prashanth Prakash

Changes in V2: Fixed compilation error on i386 This series introduces changes to reduce the time required to send a frequency transition requests to the platform while using the cppc-cpufreq driver. With these changes we see significant improvement in the average time to send freq. transition request to the platform. Profiling on an ARM platform showed that the average transaction time per request reduced from 200us to under 20us.

[PATCH V3 00/21] MMCONFIG refactoring and support for ARM64 PCI hostbridge init based on ACPI

by Tomasz Nowicki

>From the functionality point of view this series might be split into the following logic parts: 1. Make MMCONFIG code arch-agnostic which allows all architectures to collect PCI config regions and used when necessary. 2. Move non-arch specific bits to the core code. 3. Use MMCONFIG code and implement generic ACPI based PCI host controller driver. 4. Enable above driver on ARM64 Patches has been built on top of 4.4 and can be found here: git@github.com:semihalf-nowicki-tomasz/linux.git (pci-acpi-v3) NOTE, this patch set depends on Matthew's patches: http://www.spinics.net/lists/linux-pci/msg45950.html https://github.com/Vality/linux/tree/pci-fixes This has been tested on Cavium ThunderX server and QEMU. Any help in reviewing and testing is very appreciated. 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 - rebased to 4.4 v1 -> v2 - moved non-arch specific piece of code to dirver/acpi/ directory - fixed IO resource handling - introduced PCI config accessors quirks matching - moved ACPI_COMPANION_SET to generic code Liu Jiang (1): ACPI, PCI: Refine the way to handle translation_offset for ACPI resources Tomasz Nowicki (20): x86, pci: Reorder logic of pci_mmconfig_insert() function x86, pci, acpi: Move arch-agnostic MMCONFIG (aka ECAM) and ACPI code out of arch/x86/ directory pci, acpi, mcfg: Provide generic implementation of MCFG code initialization. x86, pci: mmconfig_{32,64}.c code refactoring - remove code duplication. x86, pci, ecam: mmconfig_64.c becomes default implementation for ECAM driver.

[PATCH 0/5] Update ACPI RSDP tests to be specification compliant

by Al Stone

Add in several tests that extend the testing done on the RSDP. If these tests are all passed, the RSDP being examined should be compliant with the ACPI 6.0 spec. As part of that, when creating a dummy RSDP to substitute for one that cannot be read or found, use either RsdtAddress or XsdtAddress as described in the spec. For non-arm64, either can be used, but for arm64, only the XsdtAddress is to be used. Finally, update the regression tests for RSDP. Al Stone (5): RSDP: minor cleanups to rsdp.c for checkpatch issues utilities: add a helper function for printing out architecture names ACPI tables: when bodging up an RSDP, do the right thing for the arch ACPI RSDP: flesh out the tests to check for full spec compliance.

[PATCH 0/7] Update several regression tests

[PATCH v3 0/6] ACPI compliance testing for MADT and its subtables

by Al Stone

This patch series adds in specific ACPI compliance testing for the MADT and all of its various subtables (16, currently). The first three patches add in the idea of host and target architectures -- host being the arch that FWTS is running on, and target the arch whose firmware is being tested. This is needed later in the MADT tests since what is proper changes based on the architecture the firmware supports. The fourth patch adds the detailed tests for the MADT and all but one of the subtables currently defined in ACPI 6.0. The last two patches add in the relatively new GIC ITS subtable and compliance tests for it. There are still multiple TODOs in the compliance checks; these will be added as clarification of the spec becomes available. Changes for v3: -- Add in support for the --arch=<name> parameter to specify the arch for the target firmware (default is that host == target). -- Add in the fwts_architecture typedef plus some helper functions so that tests in the future can adapt their behavior as needed, and so that the MADT tests can set themselves up properly. -- Instead of creating a new sourc file src/acpi/compliance/madt.c, replace the existing src/acpi/madt/madt.c tests since we're providing a superset. -- Various minor style and syntax corrections (from Ian Colin King) Changes for v2: -- Clean up the white space problems -- Fix errors found by checkpatch (minor syntax things) -- Fix one logic error: while MADT and FADT table revisions *should* be in sync, they seldom are, so report this as a test failure and continue to test as much as possible instead of aborting completely, in some of those cases. Al Stone (6): Start defining FWTS architectures as variables Define some utility functions for using the fwts_architecture enum Add mechanism to tell FWTS what architecture is being tested ACPI: MADT: add in compliance tests for the MADT and subtables ACPI: Add in MADT subtable description for GIC ITS subtable ACPI: MADT: add in compliance checks for the GIC ITS subtable src/acpi/madt/madt.c | 1551 +++++++++++++++++++++++++++++++------- src/lib/include/fwts.h | 1 + src/lib/include/fwts_acpi.h | 10 + src/lib/include/fwts_arch.h | 41 + src/lib/include/fwts_framework.h | 3 + src/lib/src/Makefile.am | 1 + src/lib/src/fwts_arch.c | 88 +++ src/lib/src/fwts_framework.c | 25 + 8 files changed, 1460 insertions(+), 260 deletions(-) create mode 100644 src/lib/include/fwts_arch.h create mode 100644 src/lib/src/fwts_arch.c -- 2.5.0

[PATCH 0/4] acpi: cppc optimization patches

by Prashanth Prakash

This series introduces changes to reduce the time required to send a frequency transition requests to the platform while using the cppc-cpufreq driver. With these changes we see significant improvement in the average time to send freq. transition request to the platform. Profiling on an ARM platform showed that the average transaction time per request reduced from 200us to under 20us.
