Subject: [PATCH v14 03/46] MdePkg: Add the MSR definition for the GHCB register
Date: Fri, 7 Aug 2020 14:38:48 -0500 [thread overview]
Message-ID: <372b26f6ac52fd65bf069b51982c76d87ce91831.1596829170.git.thomas.lendacky@amd.com> (raw)
In-Reply-To: <cover.1596829170.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.
