      drm/i915: Take rpm wakelock for releasing the fence on unbind · 181df2d4
      Chris Wilson authored
      Unbind the vma may happen at any time, outside of the normal GT wakeref.
      As such it relies on having a wakeref of its own. However, we can forgo
      clearing the register whilst the device is asleep and just mark it as
      unused - so that when we do wake up the device, we will clear the unused
      fence register (see i915_gem_restore_fences).

      vma/fence update required for the deferred mmio write on resume.
      v3: Don't touch i915_gem_object_set_cache_level() and leave the rpm to
      the low level routines (such as i915_vma_put_fence).
      v4: vma may be null in fence_write, so extract drm_i915_private from
      fence->i915

      drm/i915: Wake up all waiters before idling · e1c0c91b
      Chris Wilson authored
      When we idle, we wakeup the first waiter (checking to see if it missed
      an earlier wakeup) and disarm the breadcrumbs. However, we now assert
      that there are no waiter when the interrupt is disabled, triggering an
      assert if there were multiple waiters when we idled.

      drm/i915: Complain if we take too long under vblank evasion. · e1edbd44
      Maarten Lankhorst authored
      Instead of only complaining when we actually miss a vblank, always
      complain if we take longer than 100 us. This will make it easier to
      find cases where we potentially miss vblanks.

      drm/i915: Move updating color management to before vblank evasion · 567f0792
      Maarten Lankhorst authored
      This cannot be done reliably during vblank evasasion
      since the color management registers are not double buffered.
      
      The original commit that moved it always during vblank evasion was
      wrong, so revert it to before vblank evasion again.
