[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 0/3] watchdog, sbsa_gwdt: Update SBSA watchdog with the new infrastructure of watchdog.

by fu.wei＠linaro.org

From: Fu Wei <fu.wei(a)linaro.org> This patchset: (1)Try to fix an issue about min and max timeout validity check: when max_hw_heartbeat_ms is defined, this check should be skipped. (2)Use max_hw_heartbeat_ms instead of max_timeout in SBSA watchdog. (3)Set WDOG_HW_RUNNING, when SBSA watchdog is already running before it's initialized.

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

by Al Stone

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] Platforms/ARM: Juno: Update _PRT to provide interrupt type

by Punit Agrawal

The PCI Routing Table (_PRT) for Juno does not specify the Interrupt trigger type and polarity. In the absence of this information, the kernel uses PCI default interrupt type (level triggered, active low) which is incompatible with GICv2 compliant interrupt controller such as on Juno. Absence of interrupt type leads to errors such as following in kernel boot log - [ 1.353696] genirq: Setting trigger mode 8 for irq 9 failed (gic_set_type+0x0/0x5c) [ 1.478286] genirq: Setting trigger mode 8 for irq 17 failed (gic_set_type+0x0/0x5c) [ 1.563723] genirq: Setting trigger mode 8 for irq 18 failed (gic_set_type+0x0/0x5c) Fix this issue by providing the correct information (level triggered, active high) to the kernel by using the PCI Link device. Signed-off-by: Punit Agrawal <punit.agrawal(a)arm.com> --- Hi, This patch to the OpenPlatformPkg for Juno ACPI tables fixes an issue I reported earlier[0]. All feedback welcome.
