const KVM_VMSA_GPA: u64 = 0xffff_ffff_f000;Expand description
KVM hardcodes the initial VMSA at this GPA and measures it during launch finish, after all userspace-provided launch-update pages.
Keep the BSP context at this address until KVM supports userspace-supplied VMSA pages. The MSHV path validates this address against the partition’s physical address width and maps separate userspace backing for the VMSA.
