From 9688ecadd268770834cca72ac81c9aec8fb8cf2f Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Wed, 6 Nov 2013 23:02:19 +0200 Subject: [PATCH] drm/i915: Limit FBC flush to post batch flush MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Don't issue the FBC nuke/cache clean command when invalidate_domains!=0. That would indicate that we're not being called for the post-batch flush.
