BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=2198 A hypervisor is not allowed to update an SEV-ES guests register state, so when booting an SEV-ES guest AP, the hypervisor is not allowed to set the RIP to the guest requested value. Instead, an SEV-ES AP must be transition from 64-bit long mode to 16-bit real mode in response to an INIT-SIPI-SIPI sequence. This requires a 16-bit code segment descriptor. For PEI, create this descriptor in the reset vector GDT table. For DXE, create this descriptor from the newly reserved entry at location 0x28.
