    Subject[PATCH RFC v8 05/56] KVM: SEV: Require KVM_PROTECTED_VM when AMD_MEM_ENCRYPT is enabled
    Date
    AMD_MEM_ENCRYPT implies SEV support, which now relies on support
    provided by the KVM_PROTECTED_VM config option.

    An argument can be made that SEV running in non-protected-VM-mode is
    still possible, and so this should be configurable, but AMD_MEM_ENCRYPT
    will also imply SEV-SNP, for which KVM_PROTECTED_VM is required in all
    cases.

    Say yes to enable support for the encryption of system memory.
    This requires an AMD processor that supports Secure Memory
