Subject: [PATCH v6 01/42] MdePkg: Create PCDs to be used in support of SEV-ES
Date: Tue, 24 Mar 2020 12:40:15 -0500	[thread overview]
Message-ID: <911bbc068606a08bcf22c1519873d65cd2a717d0.1585071656.git.thomas.lendacky@amd.com> (raw)
In-Reply-To: <cover.1585071656.git.thomas.lendacky@amd.com>

BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=2198

Three new dynamic PCDs are needed to support SEV-ES under OVMF:
  - PcdSevEsIsEnabled: BOOLEAN value used to indicate if SEV-ES is enabled
  - PcdGhcbBase:       UINT64 value that is the base address of the GHCB
                       allocation.
  - PcdGhcbSize:       UINT64 value that is the size, in bytes, of the
                       GHCB allocation (size is dependent on the number of
                       APs).
