David Herrmann has a GSoC project for working on DRM render and mode-set nodes and so far he has been making great progress. On Sunday he posted his second revision of his unified VMA offset manager patch-set and DRM render node work.

Herrmann's work builds upon the work of others in past years with "DRM render nodes" for splitting up the mode-setting and rendering interfaces. Among the benefits that David has been aiming for is being able to run OpenCL/GPGPU clients without a compositor or display controller, improved multi-seat computing, and efficient compositor use in different scenarios.

As part of this work, on Sunday he published 20 new patches that are his second revision for the unified VMA offset manager. The patches replace the separate VMA offset managers found within GEM and TTM in the Linux kernel with a unified implementation. His 20th patch to the series provides the render nodes patch under a "request for comments" flag. Once the VMA manager is merged upstream, David intends to re-send out his render nodes code.

Many more details on this current work can be found via the email that starts off his patch series.
