/* TODO
- * Right now only scan LRI command on KBL and in inhibit context.
- * It's good enough to support initializing mmio by lri command in
- * vgpu inhibit context on KBL.
+ * In order to let workload with inhibit context to generate
+ * correct image data into memory, vregs values will be loaded to
+ * hw via LRIs in the workload with inhibit context. But as
+ * indirect context is loaded prior to LRIs in workload, we don't
+ * want reg values specified in indirect context overwritten by
+ * LRIs in workloads. So, when scanning an indirect context, we
+ * update reg values in it into vregs, so LRIs in workload with
+ * inhibit context will restore with correct values
