NVIDIA Puts Out New Fence Sync Patches

While NVIDIA may not be focusing upon supporting the Wayland Display Server at this time, they are continuing to focus upon improving the experience of their driver with the X.Org Server. Three months after putting out their most recent X Sync object patches, they are now out with a revised set.

NVIDIA's James Jones has published a new set of nine patches that go against the xorg-server for implementing the X Sync Fence Objects support. These latest patches add a DDX driver interface to allow the individual hardware drivers to redirect the operations to hardware rendering back-ends, such as what you'll likely see from NVIDIA's proprietary driver in the future once these patches have been merged to master.

For those wondering what these patches are about:
Adds support for binary sync objects. Objects are set to "triggered" using X commands that are executed relative to X rendering commands. Clients can wait for fence sync objcts to reach the triggered state using XSync APIs or using interop functionality in other APIs. This allows for efficient cross-API synchronization with X rendering operations.

The latest patch-set can be found here.
