[edk2-devel] [PATCH RESEND 0/4] Fixes for SEV-SNP CC blob and CPUID table handling
Posted by Roth, Michael via groups.io 1 year ago
(Rebased series and resending due to merge conflict with previous
submission.)

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.

----------------------------------------------------------------
Michael Roth (4):
      OvmfPkg/AmdSevDxe: Allocate SEV-SNP CC blob as EfiACPIReclaimMemory
      OvmfPkg/AmdSevDxe: Update ConfidentialComputing blob struct definition
      OvmfPkg/CcExitLib: Fix SEV-SNP XSave area size calculation
      OvmfPkg/CcExitLib: Use documented XSave area base size for SEV-SNP
