From 34d595081812da62b5357579267c4ab5eae64ac1 Mon Sep 17 00:00:00 2001 From: Ilia Mirkin Date: Sat, 15 Feb 2014 23:27:01 -0500 Subject: [PATCH] drm/nouveau: fix TTM_PL_TT memtype on pre-nv50 Commit a55409066 ("drm/nv50-: map TTM_PL_SYSTEM through a BAR for CPU access") made it possible to work with tiled memory. However mem->mm_node is not a nouveau_mem for AGP-using pre-NV50 cards, but a drm_mm_node, as created by the ttm_bo_manager_func. As such, extend the untiled check to explicitly include all pre-nv50 cards.
