From d6e4db15ed93e6c3857b904f33ac759d4c66fba9 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Wed, 4 Sep 2013 18:25:31 +0300 Subject: [PATCH] drm/i915: Fix cursor visibility checks also for the right/bottom screen edges MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit First of all we should not be looking at fb->{width,height} as those do not tell us what the actual pipe size is. Second of all we need to use >= for the comparison. So fix the comparison, and make use of the new pipe_src_{w,h} to determine the real pipe source dimensions.
