From dd1ef5e2456558876244795bb22a4d90cb24f160 Mon Sep 17 00:00:00 2001 From: Matthew Brost Date: Fri, 9 Jan 2026 17:27:35 -0800 Subject: [PATCH] drm/xe: Only toggle scheduling in TDR if GuC is running If the firmware is not running during TDR (e.g., when the driver is unloading), there's no need to toggle scheduling in the GuC.
