Subject: [PATCH v12 03/46] MdePkg: Add the MSR definition for the GHCB register
Date: Mon, 27 Jul 2020 10:25:44 -0500	[thread overview]
Message-ID: <4c660a1d7b33c9d70579015281d459dd74518213.1595863587.git.thomas.lendacky@amd.com> (raw)
In-Reply-To: <cover.1595863587.git.thomas.lendacky@amd.com>

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

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

For SEV-ES, the GHCB page address is stored in the GHCB MSR register
(0xc0010130). Define the register and the format used for register
during GHCB protocol negotiation.
