Subject: [Intel-xe] [PATCH v2 6/8] drm/xe: Ensure LR engines are not persistent
Date: Mon, 22 May 2023 20:58:06 -0700	[thread overview]
Message-ID: <20230523035808.635175-7-kode54@gmail.com> (raw)
In-Reply-To: <20230523035808.635175-1-kode54@gmail.com>

From: Matthew Brost <matthew.brost@intel.com>
Cc: Matthew Brost <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
