[edk2-devel] [PATCH v3 0/5] SEV-ES TPM enablement fixes
Posted by Lendacky, Thomas 3 years ago 
This patch series provides fixes for using TPM support with an SEV-ES
guest.

The fixes include:

- Decode ModRM byte for MOVZX and MOVSX opcodes.
- Add MMIO support for MOV opcodes 0xA0-0xA3.
- Create a new TPM MMIO ready PPI guid, gOvmfTpmMmioAccessiblePpiGuid
- Mark TPM MMIO range as un-encrypted during PEI phase for an SEV-ES
  guest and install the TPM MMIO ready PPI guid.
- Update the Tcg2Config Depex to ensure the new PEIM runs before the
  Tcg2Config PEIM

BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=3345

---

These patches are based on commit:
ab957f036f67 ("BaseTools/Source/Python: New Target/ToolChain/Arch in DSC [BuildOptions]")

Changes since:

v2:
- Update the TPM PEIM to only perform the mapping change when SEV-ES is
  active (with a comment in the code to explain why).
- Update the TPM PEIM file header comment.
- Updates to the INF file (INF_VERSION, Packages, LibraryClasses, etc.).
- Updates to PEIM file order in DSC and FDF files.
- Split out Tcg2Config Depex change to a separate patch.

v1:
- Create a TPM PEIM that will map the TPM address range as unencrypted and
  install a new PPI to indicate the mapping change is complete.
