Exercise the full driver path on real Grace and Vera hardware using
ACPI EINJ to inject CPER sections and validate the kernel log output.
KUnit covers the parser in isolation; this test covers the path from
firmware notification through GUID dispatch to decoded output.

I am not sure this belongs in the generic firmware selftests.
This test requires root, debugfs, ACPI EINJ, NVIDIA-specific vendor EINJ
metadata, a bound NVDA2012 device, and it writes EINJ controls before
triggering error_inject. Even if the selected profiles are intended to be
informational, this looks more like a platform RAS validation tool than a
generic kselftest that should run as part of the firmware selftest suite.
Would ras-tools be a better place for this? Tony Luck maintains that tree
for RAS-related test and injection tooling, and this script seems to fit
there better than tools/testing/selftests/firmware/.
