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. This patch-set renames VmgExitLib to CcExitLib (Cc means Confidential Computing). This is simple renaming and there is no logic changes. Then APIs defined in CcExitLib.h are added with a CcExit prefix. This is to make the name more meaningful. Code: https://github.com/mxu9/edk2/tree/CcExitLib.v4 v4 changes: - The previous versions of the patch-set are to first duplicate a new CcExitLib then delete the old VmgExitLib. According to this comments https://edk2.groups.io/g/devel/message/96019 it suggests renaming in a single patch is better. - Lib APIs are added with CcExit prefix, not CcExitLib prefix. v3 changes: - Rename CcExitHandleVc / CcExitHandleVe to CcExitLibHandleVc / CcExitLibHandleVe to make the nameing consistent. - Update the CcExitLib to merge the patch eff44c008d99 (OvmfPkg/VmgExitLig: HALT on #VE when access to private memory). v2 changes: - Patch #3 is added to import CcExitLib in OvmfPkg's *.dsc. This is to prevent the building from being broken in the following patches.
