So updated vblank-rework pull request, now with the polish that Mario requested applied (and reviewed by him). Also with backmerge like you've requested for easier merging. The neat thing this finally allows is to immediately disable the vblank interrupt on the last drm_vblank_put if the hardware has perfectly accurate vblank counter and timestamp readout support. On i915 that required piles of small adjustements from Ville since depending upon the platform and port the vblank happens at different scanout lines. Of course this is fully opt-in and per-device (we need that since gen2 doesn't have a hw vblank counter). * tag 'topic/vblank-rework-2014-09-12' of git://anongit.freedesktop.org/drm-intel: (22 commits) drm: Clarify vblank ts/scanoutpos sampling #defines drm: Simplify return value of drm_get_last_vbltimestamp drm: Only update final vblank count when precise ts is available drm: Really never disable vblank irqs for offdelay==0 drm: Use vblank_disable_and_save in drm_vblank_cleanup() drm: Remove drm_vblank_cleanup from drm_vblank_init error path. drm: Store the vblank timestamp when adjusting the counter during disable drm: Fix confusing debug message in drm_update_vblank_count() drm/i915: Update scanline_offset only for active crtcs drm: Kick start vblank interrupts at drm_vblank_on() drm/i915: Opt out of vblank disable timer on >gen2 drm: Add dev->vblank_disable_immediate flag drm: Disable vblank interrupt immediately when drm_vblank_offdelay<0 drm: Fix race between drm_vblank_off() and drm_queue_vblank_event() drm: Fix deadlock between event_lock and vbl_lock/vblank_time_lock drm: Reduce the amount of dev->vblank[crtc] in the code drm: Avoid random vblank counter jumps if the hardware counter has been reset drm: Have the vblank counter account for the time between vblank irq disable and drm_vblank_off() drm: Move drm_update_vblank_count() drm: Don't clear vblank timestamps when vblank interrupt is disabled ... |
