Hi Tom,
Hi Eric,
Can you describe what tests have you done for this patch serial?
I've built the OVMF package in 32, 32/64 and 64-bit configurations on
Linux using GCC as the compiler. These warnings were not emitted in those
configurations. I'll look into seeing if there is a compiler setting that
will provide these conversion warnings.
I don't have Visual Studio and so cannot test that. I can, however, fix
these warnings. Are these the only warnings you have seen?
Thanks,
Tom
I just build the UefiCpupkg. Dsc with VS2015x86 and met below errors:

Subject: [edk2-devel] [PATCH v7 01/43] MdeModulePkg: Create PCDs to be used in
support of SEV-ES
BZ:
https://nam11.safelinks.protection.outlook.com/?url=https%3A%2F%2Fbugzilla.tianocore.org%2Fshow_bug.cgi%3Fid%3D2198&data=02%7C01%7Cthomas.lendacky%40amd.com%7Cfbe4f561e0234d8450fe08d7ee7186e2%7C3dd8961fe4884e608e11a82d994e183d%7C0%7C0%7C637240043676140655&sdata=xdnfAfSLtPi3FE5olqjU7%2B4OHJBxgOTRAFR0%2BMkECLc%3D&reserved=0
Two new dynamic MdeModulePkg PCDs are needed to support SEV-ES under OVMF:
- PcdGhcbBase: UINT64 value that is the base address of the GHCB
allocation.
- PcdGhcbSize: UINT64 value that is the size, in bytes, of the
GHCB allocation (size is dependent on the number of
APs).
