[edk2-devel] [PATCH V8 13/47] UefiCpuPkg: Enable Tdx support in MpInitLib

Min,
I don't quite understand.

Of all MP services, the TDX version only supports:
* GetNumberOfProcessors
* GetProcessorInfo

And even when TDX MP returns 3 or 4 threads from GetNumberOfProcessors(), StartupAllAPs() is an NOP.
Will that cause any issue?

Can you avoid running MP driver when TDX is enabled?

Thanks,
Ray
