From de7b7d59d54852c9544a9e4fa7af719511fb5366 Mon Sep 17 00:00:00 2001 From: Ben Skeggs Date: Fri, 22 Mar 2013 12:12:17 +1000 Subject: [PATCH] drm/nouveau/ttm: allow tiled memtype on system memory buffer objects Compression not supported, and will be silently dropped. Original G80 can't handle this either and requires LINEAR memtype, though it's still possible to correctly texture and m2mf to/from these objects anyway.
