Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.

There was a nouveau DDX that relied on legacy context ioctls to work, but we fixed it years ago, give distros that have a modern DDX the option to break the uAPI and close the mess of holes that legacy context support is. Full context of the story: commit 0e975980 Author: Peter Antoine <peter.antoine@intel.com> Date: Tue Jun 23 08:18:49 2015 +0100 drm: Turn off Legacy Context Functions The context functions are not used by the i915 driver and should not be used by modeset drivers. These driver functions contain several bugs and security holes. This change makes these functions optional can be turned on by a setting, they are turned off by default for modeset driver with the exception of the nouvea driver that may require them with an old version of libdrm. The previous attempt was commit 7c510133 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Thu Aug 8 15:41:21 2013 +0200 drm: mark context support as a legacy subsystem but this had to be reverted commit c21eb21c Author: Dave Airlie <airlied@redhat.com> Date: Fri Sep 20 08:32:59 2013 +1000 Revert "drm: mark context support as a legacy subsystem" v2: remove returns from void function, and formatting (Daniel Vetter) v3: - s/Nova/nouveau/ in the commit message, and add references to the previous attempts - drop the part touching the drm hw lock, that should be a separate patch.
