From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>
Another vblank series with the following features:
- Plug a race between drm_vblank_off() and marking the crtc inactive
- Don't send zeroed vblank evens to userspace at drm_vblank_off()
- Have the user visible vblank counter account the entire time
when the crtc was active, regardless of how long vblank interrupts
were enabled
- Avoid random jumps in the user visible vblank counter if the hardware
counter gets reset
- Allow disabling vblank interrupts immediately at drm_vblank_put()
- Some polish via coccinelle
While setting drm_vblank_offdelay to 0 is now possible, I'm not sure
if we should set it 0 automatically in the i915 driver. If there are
multiple GPUs in the system that setting will affect them all, which
might have bad consequences if the other GPU doesn't have a hardware
frame counter, or if it's just buggy. So perhaps we should move that
option to be per-driver?
Ville Syrjälä (9):
drm: Always reject drm_vblank_get() after drm_vblank_off()
drm/i915: Warn if drm_vblank_get() still works after drm_vblank_off()
drm: Don't clear vblank timestamps when vblank interrupt is disabled
drm: Move drm_update_vblank_count()
drm: Have the vblank counter account for the time between vblank irq
disable and drm_vblank_off()
drm: Avoid random vblank counter jumps if the hardware counter has
been reset
drm: Disable vblank interrupt immediately when drm_vblank_offdelay==0
drm: Reduce the amount of dev->vblank[crtc] in the code
drm/i915: Leave interrupts enabled while disabling crtcs during
suspend
