Subject: [PATCH 05/14] drm/i915: Fix LP1 sprite watermarks for ILK/SNB
Date: Thu,  5 Dec 2013 15:51:32 +0200	[thread overview]
Message-ID: <1386251501-10602-6-git-send-email-ville.syrjala@linux.intel.com> (raw)
In-Reply-To: <1386251501-10602-1-git-send-email-ville.syrjala@linux.intel.com>

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

ILK/SNB don't have LP2+ watermarks for sprites. Also the LP1 sprite
watermark register has its own enable bit. Take these differences
into account when programming the LP1+ registers.
