@ -53,6 +53,29 @@ key management interface to perform common hypervisor activities such as
encrypting bootstrap code, snapshot, migrating and debugging the guest. For more
information, see the SEV Key Management spec [api-spec]_
The main ioctl to access SEV is KVM_MEM_ENCRYPT_OP. If the argument
to KVM_MEM_ENCRYPT_OP is NULL, the ioctl returns 0 if SEV is enabled
and ``ENOTTY` if it is disabled (on some older versions of Linux,
the ioctl runs normally even with a NULL argument, and therefore will
likely return ``EFAULT``). If non-NULL, the argument to KVM_MEM_ENCRYPT_OP
must be a struct kvm_sev_cmd::
struct kvm_sev_cmd {
__u32 id;
__u64 data;
__u32 error;
__u32 sev_fd;
};
The ``id`` field contains the subcommand, and the ``data`` field points to
another struct containing arguments specific to command. The ``sev_fd``
should point to a file descriptor that is opened on the ``/dev/sev``
device, if needed (see individual commands).
On output, ``error`` is zero on success, or an error code. Error codes
are defined in ``<linux/psp-dev.h>`.
KVM implements the following commands to support common lifecycle events of SEV
guests, such as launching, running, snapshotting, migrating and decommissioning.
@ -90,6 +113,8 @@ Returns: 0 on success, -negative on error
On success, the 'handle' field contains a new handle and on error, a negative value.
KVM_SEV_LAUNCH_START requires the ``sev_fd`` field to be valid.
For more details, see SEV spec Section 6.2.
