> > simply use MpInitLibUp instead of MpInitLib. To achieve this goal, we
> > include 2 CpuMpPei/CpuDxe drivers in OvmfPkgX64 and IntelTdxX64. This is
> > done by setting different FILE_GUID to these drivers (of the same name). In
> > the other hand, we import a set of MpInitLibDepLib. These libs simply
> > depend on the PPI/Protocols. While these PPI/Protocols are installed
> > according to the guest type.
