Subject: [PATCH V3 4/9] UefiCpuPkg: Use CcExitLib instead of VmgExitLib
Date: Mon,  7 Nov 2022 08:27:12 +0800	[thread overview]
Message-ID: <20221107002717.461-5-min.m.xu@intel.com> (raw)
In-Reply-To: <20221107002717.461-1-min.m.xu@intel.com>

From: Min M Xu <min.m.xu@intel.com>

BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4123

VmgExitLib once was designed to provide interfaces to support #VC handler
and issue VMGEXIT instruction. After TDVF (enable TDX feature in OVMF) is
introduced, this library is updated to support #VE as well. Now the name
of VmgExitLib cannot reflect what the lib does. So VmgExitLib is replaced
by CcExitLib.
