Hi, I am able to see APEI events (memory errors) via perft tool and now switch my context to others types of error. According to our plan, cache ECC error type would be next. I want to place tracepoints at the end of every available APEI error processing path (actually it is already done for memory errors). This way we RAS daemon could keep its eye on them. There would be of course more type of error coming from others ARM SoC peripherals. GHES driver is unrolling data structure to "Common Platform Error Record" and try to obtain error section (defined in UEFI spec). Cache ECC fall within "Processor Error Sections". Here appear problems since most of "Common Platform Error Records" are x86/IA64 oriented. So my proposals would be to: 1. Implement all available APEI errors as tracepoint that is: Processor and PCI errors 2. Mean time, create proposals for UEFI spec. toward "Common Platform Error Record" expansion for ARM architecture. This would require changing available structures and add new sections for SoC peripherals (USB, Ethernet etc.). 3. In turn, new sections for SoC peripherals in UEFI spec. would require ACPI spec. change as well, I mean new error sources for HEST table. 4. Once above proposals would be accept, we could fill in tracepoints for new error types. I would appreciate any input on this. Regards, Tomasz

[RFC V2 PATCH 0/6] ACPI: ARM: Register irq with ACPI and not DT.

by Amit Daniel Kachhap

hi, The patches in the series are work in progress and as discussed with Al Stone and Hanjun include changes in the GTDT acpi table to add missing elements for ARM platforms. Elements added are Timer frequency, interrupt count(currently 8 supported), timer ID(This will be used to invoke the correct controller). Still more TODO's are identified. * To add timer clock names. * if this __init invoking mechanism is finalised then other similar devices can use this like clock, GIC etc. * GTDT can ultimately be made CTDT(Common timer descriptor table) to other classes of timers like external exynos MCT. Changes in V2: * Added new fields in GTDT acpi table. * Infrastructure to invoke the correct timer controller. Thanks in advance.

EINJ table is fully implemented in kernel and no changes were needed to bring it up on armv7/8 arch. Along with work on EINJ coulpe of steps were done like: 1. Expand bfapei tool so it can create blob which pretend h/w registers for EINJ driver. 2. Filling address in EINJ table according to those in blob. 3. Trigger error using existing injection kernel mechanism. See commit for more details. Changes for v2: - add more descriptive commit log Changes for v3: - replace constant values with defines Tomasz Nowicki (4): bfapei: Move common functionality to separate function. bfapei: Expand bfapei tool to EINJ table testing. acpi, apei, einj: Fill in EINJ table according to address in EINJ blobs. acpi, apei, einj: Relace constant value with defines. platforms/exynos5250-arndale.acpi/einj.asl | 20 +++--- platforms/foundation-v8.acpi/einj.asl | 20 +++--- platforms/rtsm_ve-aemv8a.acpi/einj.asl | 20 +++--- tools/bfapei/bfapei.c | 104 +++++++++++++++++++++++----- tools/bfapei/bfapei.h | 30 ++++++-- tools/common/include/acpi.h | 77 ++++++++++++++++++++ 6 files changed, 215 insertions(+), 56 deletions(-) -- 1.7.9.5

Since we can trigger APEI errors using simulated SCI we do not need second patch and only fist and third patch are on special branch right now. 2. This patch set should work for UEFI but I need to check how to load APEI blob from UEFI. So yes this require additional invesitation or eventual development. Thanks for input on this. I will add another card for this. Tomasz
