https://bugzilla.kernel.org/show_bug.cgi?id=106431 Daniel Vetter <daniel@xxxxxxxx> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |daniel@xxxxxxxx --- Comment #2 from Daniel Vetter <daniel@xxxxxxxx> --- Three ways to fix this: - open-code the old behaviour (without the warning) again in nouveau, just to shut it up. - don't register vblanks with the drm core (i.e. no call to drm_vblank_init) on pre-tesla if the hw/driver can't do it since it's just a lie apparently. According to following commit at least: commit af4870e406126b7ac0ae7c7ce5751f25ebe60f28 Author: Mario Kleiner <mario.kleiner.de@xxxxxxxxx> Date: Tue May 13 00:42:08 2014 +0200 drm/nouveau/kms/nv04-nv40: fix pageflip events via special case. - fix up the underlying issue of sending the vblank events before they happen. Old intel hw is similar in that the pageflip irq from the hw happens when the flip arms, not when it completes at the next vblank. We solve that by enabling the corresponding vblank, and from the flip handler stuff the event someplace where the vblank handler can pick it up. Then on the next vblank we'll send out the event (knowing the timestamp to be accurate) and drop the vblank reference. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
