Subject: [RFC PATCH v2 14/44] UefiCpuPkg: Implement library support for VMGEXIT
Date: Thu, 19 Sep 2019 19:52:40 +0000 [thread overview]
Message-ID: <5427110cedd114a56a77b2895f0261e18b11a455.1568922728.git.thomas.lendacky@amd.com> (raw)
In-Reply-To: <cover.1568922728.git.thomas.lendacky@amd.com>
From: Tom Lendacky <thomas.lendacky@amd.com>
BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=2198
To support issuing a VMGEXIT instruction, create a library that can be
used to perform GHCB and VMGEXIT related operations and to issue the
actual VMGEXIT instruction when using the GHCB.
