Re: 回复: [edk2-devel] [PATCH 1/1] OvmfPkg/AmdSev: reserve snp pages

["Brijesh Singh" <brijesh.singh@amd.com>]

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
Brijesh
