David Airlie has been adding output master support to the xf86-video-modesetting generic DDX as well as reverse PRIME support and other changes to benefit USB display adapters.

The recent mode-setting driver work by Airlie allows for having USB devices attached, such as the DisplayLink USB adapters, while benefiting from GLAMOR acceleration on the host GPU using this X.Org DDX compatible with any DRM/KMS driver. The GLAMOR support is contingent upon OpenGL / OpenGL ES acceleration being available.


There's the output master support and other recent work was the reverse PRIME support and supporting hardware cursors for PRIME and PRIME rotation support for offloaded outputs to support 0/90/180/270 degree rotation with USB outputs and GPU outputs.
