2017-06-22efi: parse ARM processor errorTyler Baicar1-0/+54
Add support for ARM Common Platform Error Record (CPER). UEFI 2.6 specification adds support for ARM specific processor error information to be reported as part of the CPER records. This provides more detail on for processor error logs.

2015-07-15efi: Handle memory error structures produced based on old versions of standardLuck, Tony1-1/+21
The memory error record structure includes as its first field a bitmask of which subsequent fields are valid. The allows new fields to be added to the structure while keeping compatibility with older software that parses these records. This mechanism was used between versions 2.2 and 2.3 to add four new fields, growing the size of the structure from 73 bytes to 80. But Linux just added all the new fields so this test: if (gdata->error_data_length >= sizeof(*mem_err)) cper_print_mem(newpfx, mem_err); else goto err_section_too_small; now make Linux complain about old format records being too short. Add a definition for the old format of the structure and use that for the minimum size check. Pass the actual size to cper_print_mem() so it can sanity check the validation_bits field to ensure that if a BIOS using the old format sets bits as if it were new, we won't access fields beyond the end of the structure.

2013-10-23ACPI, APEI, CPER: Add UEFI 2.4 support for memory errorChen, Gong1-2/+9
In latest UEFI spec(by now it is 2.4) memory error definition for CPER (UEFI 2.4 Appendix N Common Platform Error Record) adds some new fields. These fields help people to locate memory error to an actual DIMM location.

2013-10-21ACPI, CPER: Update cper infoChen, Gong1-1/+1
We have a lot of confusing names of functions and data structures in amongs the the error reporting code. In particular the "apei" prefix has been applied to many objects that are not part of APEI. Since we will be using these routines for extended error log reporting it will be clearer if we fix up the names first.

2011-03-21ACPI, APEI, Add PCIe AER error information printing supportHuang Ying1-0/+2
The AER error information printing support is implemented in drivers/pci/pcie/aer/aer_print.c. So some string constants, functions and macros definitions can be re-used without being exported. The original PCIe AER error information printing function is not re-used directly because the overall format is quite different. And changing the original printing format may make some original users' scripts broken.

2010-12-13Add CPER PCIe error section structure and constants definitionHuang Ying1-4/+82
On some machine, PCIe error is reported via APEI (ACPI Platform Error Interface). The error data is passed from firmware to Linux via CPER PCIe error section structure. This patch adds CPER PCIe error section structure and constants definition. Signed-off-by: Huang Ying <[email protected]> Signed-off-by: Len Brown <[email protected]>
2010-08-08ACPI, APEI, Rename CPER and GHES severity constantsHuang Ying1-4/+4
The abbreviation of severity should be SEV instead of SER, so the CPER severity constants are renamed accordingly. GHES severity constants are renamed in the same way too.

2010-05-19ACPI, APEI, UEFI Common Platform Error Record (CPER) headerHuang Ying1-0/+314
CPER stands for Common Platform Error Record, it is the hardware error record format used to describe platform hardware error by various APEI tables, such as ERST, BERT and HEST etc. For more information about CPER, please refer to Appendix N of UEFI Specification version 2.3. This patch mainly includes the data structure difinition header file used by other files.
