drm

The upstream DRM subsystem repository. Maintained by Dave Airlie and Simona Vetter. Consists mostly of drivers/gpu/drm and include/drm.

See the DRM DRIVERS MAINTAINERS entry for current information on maintainers, mailing lists, bug reporting, etc.

Introduction

drm is the overall graphics subsystem integration tree, and as such works slightly different from the feature trees managed with dim:

• Normally only takes pull requests.

• Feature freeze from -rc6 to the end of the merge window, similar to other kernel subsystem trees. There’s no constantly open feature branch.

• Doesn’t have committers, just maintainers, since the pull request load is fairly minimal (for now). To keep it that way small trees are encouraged to collaborate together in drm-misc or other groups of drivers.

Note that while drm-tip is the ephemeral integration tree, drm is the permanent integration tree headed for upstream.

Repository and Branches

https://gitlab.freedesktop.org/drm/kernel

drm-next

This is the branch where all new features for the DRM core and all the GPU drivers, including drm/i915, are merged.

The drm-next branch is closed for new features at around -rc6 timeframe of the current development kernel in preparation for the upcoming merge window for the next kernel, when drm-next gets merged to Linus’ master. Thus there’s a stabilization period of about 3-5 weeks during which only bug fixes are merged to drm-next.

drm-fixes

This is the branch where all the fixes for the DRM core and all the GPU drivers for the current development kernels are merged. drm-fixes is usually merged to Linus’ master on a weekly basis.
