> UefiCpuPkg: Adds MmSaveStateLib library class You can take "Reviewed-by: Ray Ni <ray...@intel.com>" for this patch.
> UefiCpuPkg/SmmCpuFeaturesLib: Restructure arch-dependent code You can take "Reviewed-by: Ray Ni <ray...@intel.com>" for this patch. > UefiCpuPkg: Implements SmmCpuFeaturesLib for AMD Family One comment: can you please change the BASE_NAME in lib INF to "AmdSmmCpuFeaturesLib"? The BASE_NAME guides tool to generate the .Lib file in the disk. Choosing different BASE_NAME for Intel and AMD lib instance can avoid one LIB file is replaced by the other during pkg build. > UefiCpuPkg: Implements MmSaveStateLib for Intel 1. MmSaveStateLib local functions should not have "EFIAPI". Please only add "EFIAPI" for lib APIs. 2. MmSaveStateGetRegisterLma() doesn't need to carry "CpuIndex" as parameter. Can you please remove the parameter? 3. MmSaveStateGetRegisterIndex () returns wrong value for Intel processors because it uses Offset ( = 2) but Intel implementation uses Offset ( = 4). (I remember comments #1, #3 were both raised last time when I reviewed the patch.) > UefiCpuPkg: Removes SmmCpuFeaturesReadSaveStateRegister You can take "Reviewed-by: Ray Ni <ray...@intel.com>" for this patch. One more comment: Can you please avoid FILE_GUID overridden in UefiCpuPkg.dsc for Intel instance of SmmCpu driver? AMD instance can override the FILE_GUID for sure. @Wu, Jiaxin, we will need to change the close-source SmmCpuFeatureLib accordingly (separating the SaveState access code into a different lib) when this patch series are merged. > -----Original Message----- > From: Abdul Lateef Attar <abdat...@amd.com> > Sent: Saturday, May 6, 2023 12:07 PM > To: devel@edk2.groups.io > Cc: Abdul Lateef Attar <abdat...@amd.com>;
