That's purely for the uapi layer to implement the ALLOW_MODESET flag. Drivers should instead look at the state, e.g. through drm_atomic_crtc_needs_modeset(), which vmwgfx already does. Also remove the confusing comment, since checking allow_modeset is at best a micro optimization. v2: Rebase Reviewed-by: Deepak Rawat <drawat@vmware.com> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: VMware Graphics <linux-graphics-maintainer@vmware.com> Cc: Thomas Hellstrom <thellstrom@vmware.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190520223500.6032-1-daniel.vetter@ffwll.ch
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.
