Subject: [PATCH 5/7] drm/i915: Disable trickle feed for SNB/IVB cursors
Date: Tue, 30 Jan 2018 22:38:05 +0200	[thread overview]
Message-ID: <20180130203807.13721-5-ville.syrjala@linux.intel.com> (raw)
In-Reply-To: <20180130203807.13721-1-ville.syrjala@linux.intel.com>

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

We disable trickle feed whenever possible, except for the cursors
on SNB/IVB. Let's try disabling it there too if for no other reason
than consistency.
