This series was originally motivated by a deadlock, introduced in commit 1d7c71a3e2f77336df536855b0efd2dc5bdeb41b 'drm/nouveau/disp: port vblank handling to event interface', due to inverted lock order between nouveau_drm_vblank_enable() and nouveau_drm_vblank_handler() (the complete lockdep report is included in the patch 4/5 changelog). Because this series fixes the vblank event

...|Regression]System booting |when there is nothing in |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...

This series depends on the previously posted reservation api patches. 2 of them are not yet in for-next-fences branch of git://git.linaro.org/people/sumit.semwal/linux-3.x.git The missing patches are still in my vmwgfx_wip branch at git://people.freedesktop.org/~mlankhorst/linux All ttm drivers are converted to the fence api, fence_lock is removed and rcu is used in its place. qxl is the first

fence_is_signaled callback should support being run in atomic context, but not in irq context.

This series applies on top of the driver-core-next branch of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core.git Before converting ttm to the new fence interface I had to fix some drivers to require a reservation before poking with fence_obj. After flipping the switch RCU becomes available instead, and the extra reservations can be dropped again. :-) I've done at least basic
