 Anyone looking to kick it up a notch can find a list of janitorial tasks on
 the :ref:`TODO list <todo>`.
+
+Contribution Process
+====================
+
+Mostly the DRM subsystem works like any other kernel subsystem, see :ref:`the
+main process guidelines and documentation <process_index>` for how things work.
+Here we just document some of the specialities of the GPU subsystem.
+
+Feature Merge Deadlines
+-----------------------
+
+All feature work must be in the linux-next tree by the -rc6 release of the
+current release cycle, otherwise they must be postponed and can't reach the next
+merge window. All patches must have landed in the drm-next tree by latest -rc7,
+but if your branch is not in linux-next then this must have happened by -rc6
+already.
+
+After that point only bugfixes (like after the upstream merge window has closed
+with the -rc1 release) are allowed. No new platform enabling or new drivers are
+allowed.
+
+This means that there's a blackout-period of about one month where feature work
+can't be merged. The recommended way to deal with that is having a -next tree
+that's always open, but making sure to not feed it into linux-next during the
+blackout period. As an example, drm-misc works like that.
