From 75cb00dc0c9dbe5e7a971ac729384d8d05f0deb1 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Marek=20Ol=C5=A1=C3=A1k?= Date: Mon, 13 Feb 2017 17:37:05 +0100 Subject: drm/radeon: allow unaligned shader loads on CIK MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Set alignment mode to unaligned on CIK to align with amdgpu. This is needed for unaligned loads to work properly in mesa. The current setting requires dword alignment.
