Subject: Re: [PATCH V8 13/47] UefiCpuPkg: Enable Tdx support in MpInitLib
Date: Tue, 15 Mar 2022 07:57:55 +0000 [thread overview]
Message-ID: <MWHPR11MB1631148D5693499BD33210DD8C109@MWHPR11MB1631.namprd11.prod.outlook.com> (raw)
In-Reply-To: <bc73d4f9ce9acee180003b32bde611461a14f625.1647047482.git.min.m.xu@intel.com>
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
