All the plane->fb/old_fb/crtc dance of __setplane_internal() is pointless on atomic drivers. So let's just introduce a simpler version that skips all that. Ideally we could also skip the __setplane_check() as drm_atomic_plane_check() already checks for everything, but the legacy cursor/"async" .update_plane() tricks bypass that so we still need to call __setplane_check(). Toss in a FIXME to remind someone to clean this up later. v2: Use drm_drv_uses_atomic_modeset() (Daniel) Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20180705185907.9524-1-ville.syrjala@linux.intel.com
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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
