cper,edac,efi: Memory Error Record: bank group/address and chip id

2020-09-17T07:19:52Z

Updates to the UEFI 2.8 Memory Error Record allow splitting the bank field into bank address and bank group, and using the last 3 bits of the extended field as a chip identifier. When needed, print correct version of bank field, bank group, and chip identification. Based on UEFI 2.8 Table 299. Memory Error Record.

edac,ghes,cper: Add Row Extension to Memory Error Record

2020-09-17T07:19:52Z

Memory errors could be printed with incorrect row values since the DIMM size has outgrown the 16 bit row field in the CPER structure. UEFI Specification Version 2.8 has increased the size of row by allowing it to use the first 2 bits from a previously reserved space within the structure. When needed, add the extension bits to the row value printed. Based on UEFI 2.8 Table 299.

efi: cper: Add support for printing Firmware Error Record Reference

2020-05-14T09:11:20Z

While debugging a boot failure, the following unknown error record was seen in the boot logs. <...> BERT: Error records from previous boot: [Hardware Error]: event severity: fatal [Hardware Error]: Error 0, type: fatal [Hardware Error]: section type: unknown, 81212a96-09ed-4996-9471-8d729c8e69ed [Hardware Error]: section length: 0x290 [Hardware Error]: 00000000: 00000001 00000000 00000000 00020002 ................ [Hardware Error]: 00000010: 00020002 0000001f 00000320 00000000 ........ ....... [Hardware Error]: 00000020: 00000000 00000000 00000000 00000000 ................ [Hardware Error]: 00000030: 00000000 00000000 00000000 00000000 ................ <...> On further investigation, it was found that the error record with UUID (81212a96-09ed-4996-9471-8d729c8e69ed) has been defined in the UEFI Specification at least since v2.4 and has recently had additional fields defined in v2.7 Section N.2.10 Firmware Error Record Reference. Add support for parsing and printing the defined fields to give users a chance to figure out what went wrong. Signed-off-by: Punit Agrawal Cc: Ard Biesheuvel Cc: "Rafael J.

CPER: Remove unnecessary use of user-space types

2019-04-13T16:17:36Z

"__u32" and similar types are intended for things exported to user-space, including structs used in ioctls; see include/uapi/asm-generic/int-l64.h. They are not needed for the CPER struct definitions, which not exported to user-space and not used in ioctls. Replace them with the typical "u32" and similar types. No functional change intended. The reason for changing this is to remove the question of "why do we use __u32 here instead of u32?" We should use __u32 when there's a reason for it; otherwise, we should prefer u32 for consistency.

efi: Decode IA32/X64 Processor Error Section

2018-05-14T06:57:47Z

Recognize the IA32/X64 Processor Error Section. Do the section decoding in a new "cper-x86.c" file and add this to the Makefile depending on a new "UEFI_CPER_X86" config option. Print the Local APIC ID and CPUID info from the Processor Error Record. The "Processor Error Info" and "Processor Context" fields will be decoded in following patches. Based on UEFI 2.7 Table 252.

efi: Parse ARM error information value

2018-01-03T13:03:48Z

ARM errors just print out the error information value, then the value needs to be manually decoded as per the UEFI spec. Add decoding of the ARM error information value so that the kernel logs capture all of the valid information at first glance. ARM error information value decoding is captured in UEFI 2.7 spec tables 263-265.
