GK20A does not embed a dedicated COPY engine and thus cannot allocate the copy channel that nouveau_accel_init() attempts to create. It also lacks any display hardware, so the creation of a software channel does not apply neither.

Hello List, I am trying to solve bug 58556 [1], but I will need some help as I don't understand all that is going on. The system is composed of an NV96 (9600 GT) and an NVAC (9400 M) card; acceleration is disabled, otherwise the system hangs at boot after initialising the NV96 card. The problem consist of a complete garbage screen in console mode, and a one-third gabage screen in GUI.

...|with Call Trace |DCB on 3.13-rc --- Comment #6 from Ilia Mirkin <imirkin at alum.mit.edu> --- Looks like you have no outputs. I think this will lead to chan->vblank.nr_event = pdisp->vblank->index_nr; failing in nv50_software_context_ctor, called from nouveau_accel_init since pdisp->vblank == NULL. I suspect that ->index_nr is at offset 0x130 which explains the CR2 that you see. As a temporary workaround, booting with nouveau.noaccel=1 will avoid the crash (and also remove your ability to use the card). -- You are receiving this mail because: You are the...

...5e120f6e4b3f35b741c5445dfc755f50128c3c44 which actually introduces the nv84+ fence mechanism. This had actually previously occurred to me, but a quick thing to try out is to switch to the nv17 fence and see what happens. You can do this by editing the logic in drivers/gpu/drm/nouveau/nouveau_drm.c:nouveau_accel_init, and just replace nv84_fence_create with nv50_fence_create (which will make a nv50+ appropriate nv17 fence impl). -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
