+/**
+ * struct drm_xe_query_uc_fw_version - query a micro-controller firmware version
+ *
+ * Given a uc_type this will return the major, minor, patch and branch version
+ * of the micro-controller firmware.
+ *
+ * The @uc_type can be:
+ *  - %DRM_XE_QUERY_UC_TYPE_GUC_SUBMISSION - This is the GuC Submission Version,
+ * a.k.a 'VF version'. It is not the actual GuC blob version. A running GuC can
+ * support multiple VF APIs with different Submission Versions. This version is
+ * negotiated by the VF KMD with GuC during VF initialization. In most of the
+ * current available GuC blobs, this is a 1-1 relationship where the Submission
+ * version could be inferred from the running version and vice-versa. However,
+ * the submission version is the most useful information for the user space
+ * perspective and needs.
+ *  - %DRM_XE_QUERY_TYPE_HUC - The actual HuC blob that is currently running
+ * in the platform. It returns 0 when HuC is not currently loaded.
