From a42a57196ad897e7686944488b23f5d2b6496372 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Tue, 7 Jan 2014 16:14:08 +0200 Subject: drm/i915: Fix watermark code for BDW MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Looks like I forgot to update the ILK/SNB/IVB watermark patches to deal with BDW. Add the relevant BDW checks to make sure we take the HSW codepaths on BDW as well.
