[PATCH v2 0/2] acpi, apei: add BERT support

Show all headers | View raw

From: Fu Wei <fu.wei@linaro.org>

ACPI/APEI is designed to verifiy/report H/W errors, like Corrected
Error(CE) and Uncorrected Error(UC). It contains four tables: HEST,
ERST, EINJ and BERT. The first three tables have been merged for
a long time, but because of lacking BIOS support for BERT, the
support for BERT is pending until now. Recently on ARM 64 platform
it is has been supported. So here we come.

The following log is a BERT record after system reboot because of
hitting a fatal error.

BERT: Obtained BERT iomem region <00000000fe801000-00000000fe802000> for BERT.
[Hardware Error]: Error record from previous boot:
[Hardware Error]: event severity: fatal
[Hardware Error]:  Error 0, type: fatal
[Hardware Error]:   section_type: memory error
[Hardware Error]:   physical_address: 0x00000000fe800000
[Hardware Error]:   physical_address_mask: 0x0000000000000fff
[Hardware Error]:   card: 0 module: 1 bank: 0 device: 1 row: 1 column: 1 bit_pos

Changelog:
v2: Delete EXPORT_SYMBOL_GPL(bert_disable), because "bert_disable" is only used
    in bert.c for now.
    Do some code-style cleanups.

v1: The first upstream version submitted in linux-acpi mailing list:
