From 774c389fae5e5a78a4aa75f927ab59fa0ff8a0d2 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Marek=20Ol=C5=A1=C3=A1k?= Date: Fri, 1 Mar 2013 13:40:31 +0100 Subject: drm/radeon: don't check mipmap alignment if MIP_ADDRESS is FMASK MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The MIP_ADDRESS state has 2 meanings. If the texture has one sample per pixel, it's a pointer to the mipmap chain. If the texture has multiple samples per pixel, it's a pointer to FMASK, a metadata buffer needed for reading compressed MSAA textures. The mipmap alignment rules do not apply to FMASK.
