[PATCH 00/23] drm: Eliminate plane->fb/crtc usage for atomic drivers

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>

I really just wanted to fix i915 to re-enable its planes afer load
detection (a two line patch). This is what I actually ended up with
after I ran into a framebuffer refcount leak with said two line patch.

I've tested this on a few i915 boxes and so far it's looking
good. Everything else is just compile tested.
