Subject: [Intel-gfx] [PATCH 19/23] drm/i915: Use ww pinning for intel_context_create_request()
Date: Wed, 20 May 2020 15:00:26 +0200 [thread overview]
Message-ID: <20200520130030.1014994-19-maarten.lankhorst@linux.intel.com> (raw)
In-Reply-To: <20200520130030.1014994-1-maarten.lankhorst@linux.intel.com>
We want to get rid of intel_context_pin(), convert
intel_context_create_request() first. :)
