Note: Before performing a reset on an RCS or CCS engine, the GuC will attempt to preempt-to-idle the other non-hung RCS/CCS engines to avoid impacting other clients (since some shared modules will be reset). If other engines are executing non-preemptable workloads, the impact is unavoidable and some work may be lost.
