[RFC PATCH] ACPI: ASL: Add GTDT table for exynos5440

by Amit Daniel Kachhap

Using exynos5440 for testing the ACPI interrupt mapping/parsing as this platform uses arm internal timer. Signed-off-by: Amit Daniel Kachhap <amit.daniel(a)samsung.com> --- Hi, As requested by Al Stone and Hanjun I am sending the GTDT asl table. I am not using arndale for testing this as it uses external arm timer coming from exynos combiner which may be complex to use at this stage.

[PATCH 0/3] Hacks for APEI tables test.

by Tomasz Nowicki

These commits were created to make APEI tables testable. All should be pushed to some test brunch so anybody could test it on his own, reused etc. Tomasz Nowicki (3): acpi, apei, erst: Reserve no cachable region for persistent storage. acpi, apei, einj: Hack EINJ driver to enable injection GHES and kernel panic from userspace. apci, apei, arm64: Make some space for APEI blob. arch/arm64/boot/dts/foundation-v8-acpi.dts | 2 +- drivers/acpi/apei/einj.c | 27 +++++++++++++++++++++++++++ drivers/acpi/apei/erst.c | 2 +- 3 files changed, 29 insertions(+), 2 deletions(-) -- 1.7.9.5

Cherry-picked early_ioremap patch for aarch64

by Al Stone

The patch below adds in an early_ioremap for aarch64 allowing the ACPI code to function. It's still under discussion upstream and will likely change but it will allow work to continue on aarch64 in the short-term. Please test and let us know if it works or if it uncovers any other interesting issues. -- ciao, al ----------------------------------- Al Stone Software Engineer Linaro Enterprise Group al.stone(a)linaro.org -----------------------------------

[PATCH 0/2] Boot Error Record Table (BERT) support

by Tomasz Nowicki

This is re-use existing patch submitted by Huang Ying <ying.huang(a)intel.com> with one small modification (see commits). The first idea was to use just printk to inform about any errors that were not consumed by OS. Errors listed in HEST table should point to the same "Error status block" ESB structures as BERT does. OS handling errors should clear errors status bit in ESB for given error at the end of error recovery procedure. Case where error appeared to be too serious OS can reset machine immediately without clearing bit in ESB. During boot, kernel examine each error status bit from ESB list (pointed from BERT) and see if there are any unhandled errors. BERT table was tested along with HEST and EINJ driver, in the following way: 1. Fill in ESB using EINJ hacked driver and do not clear erros status in ESB, this way unhandler error is simulated and BERT table could be used later: root@localhost:~# echo 1 > /sys/kernel/debug/apei/einj/error_inject 2. Reboot machin and check whether BERT driver notice injected error: ... [ 2.518179] [Hardware Error]: Error record from previous boot: [ 2.523342] [Hardware Error]: APEI generic hardware error status [ 2.548457] [Hardware Error]: severity: 1, fatal [ 2.574705] [Hardware Error]: section: 0, severity: 0, recoverable [ 2.584010] [Hardware Error]: flags: 0x00 [ 2.587937] [Hardware Error]: section_type: memory error ... 3. Kernel clear status bit so next boot would not print it again.

[PATCH] ARM: with certain kernel configs, a stub function definition was missing.
