The bits intended to control the 3D GPU clock need to be enabled for the

Invoke a hypercall when a memory region is changed from encrypted ->
decrypted and vice versa. Hypervisor needs to know the page encryption
status during the guest migration.

For all unencrypted guest memory regions such as S/W IOTLB
bounce buffers and for guest regions marked as "__bss_decrypted",
ensure that DBG_DECRYPT API calls are bypassed.
The guest memory regions encryption status is referenced using the
shared pages list.

Reset the host's shared pages list related to kernel
specific page encryption status settings before we load a
new kernel by kexec. We cannot reset the complete
shared pages list here as we need to retain the
UEFI/OVMF firmware specific settings.

The guest support for detecting and enabling SEV Live migration
feature uses the following logic :
- kvm_init_plaform() invokes check_kvm_sev_migration() which
checks if its booted under the EFI
- If not EFI,
i) check for the KVM_FEATURE_CPUID
ii) if CPUID

Introduce a new AMD Memory Encryption GUID which is currently
used for defining a new UEFI environment variable which indicates
UEFI/OVMF support for the SEV live migration feature. This variable
is setup when UEFI/OVMF detects host/hypervisor support for SEV
live migration

This hypercall is used by the SEV guest to notify a change in the page
encryption status to the hypervisor. The hypercall should be invoked
only when the encryption attribute is changed from encrypted -> decrypted
and vice versa. By default all guest pages are considered

KVM hypercall framework relies on alternative framework to patch the
VMCALL -> VMMCALL on AMD platform. If a hypercall is made before
apply_alternative() is called then it defaults to VMCALL. The approach
works fine on non SEV guest. A VMCALL would causes #UD, and hypervisor

The series add support for AMD SEV guest live migration commands. To protect the
confidentiality of an SEV protected guest memory while in transit we need to
use the SEV commands defined in SEV API spec [1].
SEV guest VMs have the concept of private and shared memory. Private

What protects this global variable? Or is there some subtle reason it
doesn't need protection, in which case,
