Subject: [PATCH v10 01/46] MdeModulePkg: Create PCDs to be used in support of SEV-ES
Date: Tue, 14 Jul 2020 09:27:32 -0500	[thread overview]
Message-ID: <8303617f29e455a510a296dfeb67e6a8ae10e9ad.1594736896.git.thomas.lendacky@amd.com> (raw)
In-Reply-To: <cover.1594736896.git.thomas.lendacky@amd.com>

From: Tom Lendacky <thomas.lendacky@amd.com>

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

Two new dynamic MdeModulePkg PCDs are needed to support SEV-ES under OVMF:
  - 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).
