Subject: [Intel-gfx] [PATCH 37/61] drm/i915: Add missing ww lock in intel_dsb_prepare.
Date: Fri, 2 Oct 2020 14:59:15 +0200 [thread overview]
Message-ID: <20201002125939.50817-38-maarten.lankhorst@linux.intel.com> (raw)
In-Reply-To: <20201002125939.50817-1-maarten.lankhorst@linux.intel.com>
Because of the long lifetime of the mapping, we cannot wrap this in a
simple limited ww lock. Just use the unlocked version of pin_map,
because we'll likely release the mapping a lot later, in a different
thread.
