v15: 28jan2022
- Changes to build_erst() and ACTION/VALUE context struct
setup, per Michael.
v14: 26jan2022
- Changed build_erst() to utilize a context structure for
generating accesses to ACTION and VALUE, per Michael Tsirkin.
- Other simplification per Ani Sinha.
v13: 24jan2022
- v12 erroneously omitted step 6 of bios-tables-test.c, this
has step 6 included.
- No other changes to v12.
v12: 10jan2022
- Converted macros in build_erst() to uppert to follow coding
style, as pointed out by Michael Tsirkin.
- And few items to help further simplify build_erst().
v11: 15dec2021
- Simplified build_erst() via feedback from Michael Tsirkin
- Addressed additional feedback from Ani Sinha
v10: 9dec2021
- Addressed additional feedback from Ani Sinha
v9: 2dec2021
- Addressed feedback from Ani Sinha
v8: 15oct2021
- Added Kconfig option for ERST, per Ani Sinha
- Fixed patch ordering, per Ani
v7: 7oct2021
- style improvements, per Igor
- use of endian accessors for storage header, per Igor
- a number of optimizations and improvements, per Igor
- updated spec for header, per Igor
- updated spec for rst format, per Michael Tsirkin
- updated spec for new record_size parameter
Due to changes in the spec, I am not carrying the
Acked-by from Ani Sinha.
- changes for and testing of migration to systems with
differing ERST_RECORD_SIZE
v6: 5aug2021
- Fixed compile warning/error, per Michael Tsirkin
- Fixed mingw32 build error, per Michael
- Converted exchange buffer to MemoryBackend, per Igor
- Migrated test to PCI, per Igor
- Significantly reduced amount of copying, per Igor
- Corrections/enhancements to acpi_erst.txt, per Igor
- Many misc/other small items, per Igor
v5: 30jun2021
- Create docs/specs/acpi_erst.txt, per Igor
- Separate PCI BARs for registers and memory, per Igor
- Convert debugging to use trace infrastructure, per Igor
- Various other fixups, per Igor
v4: 11jun2021
- Converted to a PCI device, per Igor.
- Updated qtest.
- Rearranged patches, per Igor.
v3: 28may2021
- Converted to using a TYPE_MEMORY_BACKEND_FILE object rather than
internal array with explicit file operations, per Igor.
- Changed the way the qdev and base address are handled, allowing
ERST to be disabled at run-time. Also aligns better with other
existing code.
v2: 8feb2021
- Added qtest/smoke test per Paolo Bonzini
- Split patch into smaller chunks, per Igor Mammedov
- Did away with use of ACPI packed structures, per Igor Mammedov
v1: 26oct2020
- initial post
