--- Comment #4 from Ilia Mirkin <[email protected]> --- There are two issues: (a) The null deref in the kernel when putting the card back to sleep (b) The fact that init of the card fails To mitigate the first, you could boot with "nouveau.runpm=0". 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 ) -- You are receiving this mail because: You are the assignee for the bug.
