Sync MESAPI__RESET with the firmware definition (the use_connected_queue_index[_p1] flags and the trailing active_vmids / connected_queue_index[_p1] fields) and program the connected queue index from the detect input, so the MES can locate a CP-frozen gfx user queue via its CP_CNTX_STAT fallback. An older MES firmware ignores the flags (previously reserved bits) and falls back to query_status, so no firmware version gate is required.
