efi: Parse ARM error information value

2018-01-03T13:03:48+00:00

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.

efi: Move ARM CPER code to new file

2018-01-03T13:03:48+00:00

The ARM CPER code is currently mixed in with the other CPER code. Move it
to a new file to separate it from the rest of the CPER code.

efi: switch to use new generic UUID API

2017-08-30T12:40:40+00:00

There are new types and helpers that are supposed to be used in new code.

As a preparation to get rid of legacy types and API functions do
the conversion here.

efi: parse ARM processor error

2017-06-22T14:43:47+00:00

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.

efi: Handle memory error structures produced based on old versions of standard

2015-07-15T12:30:38+00:00

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.

ACPI, APEI, CPER: Add UEFI 2.4 support for memory error

2013-10-23T17:10:20+00:00

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.

ACPI, CPER: Update cper info

2013-10-21T22:12:00+00:00

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.
