Subject: [Intel-xe] [PATCH v4 5/7] drm/xe/gt: tweak placement for signalling TLB fences after GT reset
Date: Wed,  5 Jul 2023 17:06:08 +0100	[thread overview]
Message-ID: <20230705160602.237213-14-matthew.auld@intel.com> (raw)
In-Reply-To: <20230705160602.237213-9-matthew.auld@intel.com>

Assumption here is that submission is disabled along with CT, and full
GT reset will also nuke TLBs, so should be safe to signal all in-flight
TLB fences, but only after the actual reset so move the placement
slightly.
