BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=4654 Currently, the first time an AP is started for an SEV-SNP guest, it relies on the VMSA as set by the hypervisor. If the list of APIC IDs has been retrieved, this is not necessary. The list of APIC IDs will be identified by a GUIDed HOB. If the GUIDed HOB is present, use the SEV-SNP AP Create protocol to start the AP for the first time and each time thereafter.
