Subject: [PATCH 27/28] drm/xe/vf: Add debug prints for GuC replaying state during VF recovery
Date: Tue, 16 Sep 2025 20:46:14 -0700	[thread overview]
Message-ID: <20250917034615.3977603-28-matthew.brost@intel.com> (raw)
In-Reply-To: <20250917034615.3977603-1-matthew.brost@intel.com>

Helpful to manually verify the GuC state machine can correctly replay
the state during a VF post-migration recovery. All replay paths have
been manually verified as triggered and working during testing.
