Subject: [Intel-xe] [PATCH 6/8] drm/xe: Ensure LR engines are not persistent
Date: Sun, 21 May 2023 18:50:38 -0700	[thread overview]
Message-ID: <20230522015040.3849776-7-matthew.brost@intel.com> (raw)
In-Reply-To: <20230522015040.3849776-1-matthew.brost@intel.com>

With our ref counting scheme long running (LR) engines only close
properly if not persistent, ensure that LR engines are non-persistent.

v2: spell out LR
