From f727b490efd0941a8d720fd07012dcb7f0740f77 Mon Sep 17 00:00:00 2001 From: Daniel Vetter Date: Wed, 20 Nov 2013 15:02:10 +0100 Subject: [PATCH] drm/i915: Fix gen3 self-refresh watermarks MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This regression has been introduced in commit 4fe8590a921d0b2e36e542dbfa89a8c5993f5a3f Author: Ville Syrjälä Date: Wed Sep 4 18:25:22 2013 +0300 drm/i915: Use adjusted_mode appropriately when computing watermarks I guess we should renable the enabled local variable into something a notch more descriptive, but that's something for -next. The effect on my i945gme netbook is pretty severe amounts of underruns - usually the very first pixel gets used for the entire screeen.
