<span class="quote">> For my normal work activities I'm carrying a patch that reverts the

<span class="quote">> drm/i915: Calculate watermark configuration during atomic check (v2)
> drm/i915: Don't set plane visible during HW readout if CRTC is off
> drm/i915: Calculate ILK-style watermarks during atomic check (v3)
> drm/i915: Calculate pipe watermarks into CRTC state (v3)
> drm/i915: Refactor ilk_update_wm (v3)
> drm/i915: Drop intel_update_sprite_watermarks</span >
>
<span class="quote">> So I guess the sprite update thing is very likely the first bad commit.
> I'm also noticing that the screen stays black for _way_ too much time
