From d9e1551ec1391dee9db8b1121007f616454e1ca7 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Mon, 27 Mar 2017 21:55:45 +0300 Subject: [PATCH] drm/i915: Relax 845/865 CURBASE alignemnt requirement to 32 bytes MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Supposedly 845/865 require only 32 byte alignment for CURBASE. Let's relax the checks to allow that instead of demanding 4KiB alignment. This will allow cursor panning in 8 pixel units.
