David Airlie, the Linux kernel DRM maintainer and the Red Hat employee responsible for a good portion of the open-source ATI Linux driver work, has announced changes in how he will be handling his DRM kernel branches and the addition of some new branches for ATI customers wishing to experiment with the latest Radeon driver code.
Under this new plan David will be controlling the drm-core-next, drm-radeon-next, drm-next, and drm-radeon-testing. Descriptions of these Git branches for the Direct Rendering Manager code can be found on the dri-devel mailing list
The important branches for desktop users wishing to experiment with the latest code is drm-next and drm-radeon-testing. The drm-next branch will pull frequently from the other Git branches like drm-radeon-next and drm-intel-next into this central location. The drm-next branch is likely what will be pulled into the next Linux kernel development cycle for mainline inclusion. For those with ATI Radeon hardware looking to use the latest DRM code under a kernel mode-setting environment, drm-radeon-testing will contain all of the bleeding edge ATI work.
