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. 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.

Hi Jiewen, Changing the name of a library is a non-backwards compatible change from a platform DSC file perspective for downstream consumers. Whenever any type of non-backwards compatible change is made, we need to highlight that in the commit messages and the Patch #0. The rename is clearly documented in this series. I am only asking that the non-backwards compatible aspect be highlighted along with instructions on what updates to a downstream platform DSC are required. We can work on ways to collect this type of information into a release note format so the changes required to move from one release to the next are clearly documented.
