(Mainly a resend of v1, but rolled in Gerd's Acked-by's, addressed
new coding style check in the CI, and updated Cc list)
Here are a number of fixes related to OVMF handling of the SEV-SNP
Confidential Computing blob and CPUID table.
Patch #1 is a fix for recently-reported issue that can cause
significant problems with some SEV-SNP guest operating systems.
Please consider applying this patch directly if the other
patches in this series are held up for any reason.
Patches 2-4 are minor changes for things that aren't currently
triggered in practice, but make OVMF's SEV-SNP implementation more
robust for different build/hypervisor environments in the future.
Patch #2 was submitted previously, but refreshed here to apply
cleanly on top of Patch #1, with no other functional changes since
the initial review.
v2:
- rebased/retested on latest master
- replaced usage of __FUNCTION__ with __func__ to comply with new CI
test cases
