Vera is NVIDIA's next-generation server SoC. It reports hardware
errors via ACPI GHES using a CPER section format distinct from the
existing Grace section. Without this series, firmware-reported errors
on Vera platforms are received but not decoded.
Patch 1 refactors the Grace decoder to separate parsing from logging,
preparing it for testability and for sharing types with the new Vera
decoder.
Patches 2-4 add the Vera decoder, KUnit coverage for both decoders,
and an EINJ-based kselftest for end-to-end validation on real hardware.
