> Subject: [PATCH v2 0/2] AMD procesor MSR_IA32_MISC_ENABLE
>
> AMD processor does not support MSR_IA32_MISC_ENABLE register.
> Accessing this register on AMD causes an unhandled exception in
> SmmEntry.nasm and a subsequent failure to boot since this is too early in
> SMM path for the exception handler to be loaded.
>
> First, to distinguish between AMD and other processors, refactor
> StandardSignatureIsAuthenticAMD into BaseUefiCpuLib. So there is only one
> copy in the source. All changed modules already include UefiCpuLib either
> directly or indirectly so could not easly split first patch.
>
> Second, Skip manipulation of MSR_IA32_MISC_ENABLE register if running on
> an AMD processor.
>
> Tested on AMD X64 hardware.
> OvmfIa32 and OvmfIa32X64 on Intel hardware.
