From 6ec3b2a4b1d41b83a4721d06b42c49f55e695cbf Mon Sep 17 00:00:00 2001 From: =?utf8?q?Marek=20Ol=C5=A1=C3=A1k?= Date: Mon, 24 Oct 2016 19:05:10 +0200 Subject: [PATCH] winsys/amdgpu: fix radeon_surf::macro_tile_index for imported textures MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Maybe this is why SDMA has been broken for many amdgpu users? SDMA is the only block which is used with imported textures and relies on this variable. DB also uses it, but it doesn't get imported textures, so it's unaffected. I do get SDMA failures on Tonga before this patch if R600_DEBUG=testdma is changed to use imported textures.
