Subject: [PATCH v3 16/36] drm/xe/vf: Close multi-GT GGTT shift race
Date: Sun, 28 Sep 2025 19:55:22 -0700	[thread overview]
Message-ID: <20250929025542.1486303-17-matthew.brost@intel.com> (raw)
In-Reply-To: <20250929025542.1486303-1-matthew.brost@intel.com>

As multi-GT VF post-migration recovery can run in parallel on different
workqueues, but both GTs point to the same GGTT, only one GT needs to
shift the GGTT. However, both GTs need to know when this step has
completed. To coordinate this, share the VF config lock among all GTs
that share a GGTT, and perform the GGTT shift under this lock. With
shift being done under the lock, storing the shift value becomes
unnecessary.

v3:
 - Update commmit message (Tomasz)
