1. InitializeSmmCpuServices(): please keep the ASSERT_EFI_ERROR (Status) for CpuService protocol installation. Will add assert. 2. SmmWaitForApArrival (): Can you remove the BlockingMode parameter because I cannot find any invocation using FALSE as parameter. Have removed in patchv4. 3. mSmmMpSyncData->AllApArrivedWithException: where is this variable assigned to TRUE? Have added in patchv4. 4. SmmCpuRendezvousProtocolNotify(): Function header is incorrect (I saw "Report Status Code"). Can you add comments to explain why protocol notification is needed instead of using library constructor to locate the protocol? Feature need to support MM_STANDALONE and DXE_SMM_DRIVER driver. They have different entry function parameter. Will add comment in function header. 5. Lib: SmmWaitForAllProcessor(): Can you add comments to explain why (mSmmCpuRendezvous == NULL) is a success? And this API is the same as the internal function name in PiSmmCpuDxe driver. It may cause confusing. Can you change that internal function to use a different name? 1) If SmmCpuRendezvous service do not locate, it means the platform have not setup and influence cpu rendezvous. Will add comment in function header. 2) For this, I plan to modified name of SmmWaitForAllProcessor in SmmCpuRendezvousLib to be SmmCpuRendezvous() and keep PiSmmCpuDxe driver the same.

REF： https://bugzilla.tianocore.org/show_bug.cgi?id=3815 This patch define a new Protocol with the new services SmmWaitForAllProcessor(), which can be used by SMI handler to optionally wait for other APs to complete SMM rendezvous in relaxed AP mode. A new library SmmCpuRendezvousLib is provided to abstract the service into library API to simple SMI handler code. Patch_v3 modified to pass CI test. (1)Add SmmCpuRendezvousLib.inf into UefiCpuPkg.dsc <LibraryClasses>/<Component> (2)Add SmmCpuRendezvousLib.h in UefiCpuPkg.dec [Libraryclasses.IA32, Libraryclasses.x64] (3) Some UncrustifyCheck modifications.
