Subject: [PATCH V4 13/31] UefiCpuPkg: Enable Tdx support in MpInitLib
Date: Mon, 13 Dec 2021 20:56:44 +0800 [thread overview]
Message-ID: <fc6adc09b9ef160296b9271e18349195579f34a7.1639399598.git.min.m.xu@intel.com> (raw)
In-Reply-To: <cover.1639399598.git.min.m.xu@intel.com>
RFC: https://bugzilla.tianocore.org/show_bug.cgi?id=3429
In TDVF BSP and APs are simplified. BSP is the vCPU-0, while the others
are treated as APs.
So MP intialization is rather simple. The processor info is retrieved by
TDCALL, ApWorker is not supported, BSP is always the working processor,
while the APs are just in a wait-for-precedure state.
