Since commit e5ca5dec3111772ade1cbbead50c0c594a49778d (bisected, drm/nouveau:
remove remnants of nouveau_pgraph_engine) to nouveau/linux-2.6, I get NULL

So it appears the noaccel case has been broken by said git commit. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. ^ permalink raw reply [flat|nested] 4+ messages in thread

On NV50/NVA0 cards, engine->fifo.init = nv50_fifo_init (nv50_fifo.c file) and this function is responsible to fill pfifo->playlist array, which is not done with nouveau_noaccel enabled. When nv50_fifo_playlist_update() is called, accessing pfifo->playlist (which was not initialized) triggers the NULL pointer dereference. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. ^ permalink raw reply [flat|nested] 4+ messages in thread
