From dace8cb0032f57ea67c87b3b92ad73c89dd2db44 Mon Sep 17 00:00:00 2001 From: Zhanjun Dong Date: Tue, 10 Mar 2026 18:50:37 -0400 Subject: [PATCH] drm/xe/guc: Ensure CT state transitions via STOP before DISABLED The GuC CT state transition requires moving to the STOP state before entering the DISABLED state. Update the driver teardown sequence to make the proper state machine transitions.
