However you still wouldn't get working accel with nouveau. The claim by NVIDIA was that the graph-not-powered-up problem was restricted to GK104/GK106. But looking at the latest code, it seems like it runs on GK107 as well (not in Ben's repo anymore, but still in linux-3.16) and perhaps has the reverse effect there. I wonder if a patch like diff --git a/nvkm/engine/graph/nve4.c b/nvkm/engine/graph/nve4.c index 51e0c07..4dd376e 100644 --- a/nvkm/engine/graph/nve4.c +++ b/nvkm/engine/graph/nve4.c @@ -350,7 +350,7 @@ nve4_graph_oclass = &(struct nvc0_graph_oclass) { .ctor = nvc0_graph_ctor, .dtor = nvc0_graph_dtor, .init = nve4_graph_init, - .fini = nve4_graph_fini, + .fini = _nouveau_graph_fini, }, .cclass = &nve4_grctx_oclass, .sclass = nve4_graph_sclass, will help you out. (You'll need to apply it with care... cd into drivers/gpu/drm/nouveau/core and apply it with patch -p2 )</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
