@S, Ashraf Ali I think we need to return 64bit pointer in 64bit build, please
help to verify and confirm.
Thanks,

Thanks for good catch, Ray!
@Desimone, Nathaniel L and @Ma, Maurice, please also share your comments for
this change.
I think we could directly change CoreStack size and implementation to support
64bits build because both FspGlobalData and SwapStack() are FSP
private/internal usage.

If we don't handle it, it will Segmentation fault.

Greetings!
We implemented a driver that runs an EFI application on the system using the
LoadImage and StartImage functions present in the EFI_BOOT_SERVICES (gBS)

Hi Liming,
The said PCD is applicable for the SNP. SNP is supported on x86 64-bit
only, and most of the development is focused around Qemu/OVMF. In other
words, the Bhyve, Xen, and CloudHV do not support the SNP yet. We can
revisit it when those HV starts supporting the SNP.
thanks

Hi all,
Please check the Xhci log below. There's a low probability that the Xhci module
will assert during a machine startup.

This is the first of cleanup for SEV MemEncryptLib. The library uses
the CPUID followed by the MSR read to determine whether SEV is enabled.
Now that we have a workarea concept, the logic can be simplified to
store the msr status in workarea and use that to build PCDs and then
later simply use

In order to probe the SEV feature the BaseMemEncryptLib and Reset vector
reads the SEV_STATUS MSR. Cache the value on the first read in the
workarea. In the next patches the value saved in the workarea will
be used by the BaseMemEncryptLib.

Improve the MemEncryptSev{Es,Snp}IsEnabled() to use the SEV_STATUS MSR
value saved in the workarea. Since workarea is valid until the PEI phase,
so, for the Dxe phase use the PcdConfidentialComputingGuestAttr to
