Linux kernel source tree
5d32bcd0a7
Factor out to a new function the logic to calculate an FB plane's normal-view size. Instead of using intel_remapped_plane_info, which is related only to remapping, add a helper to get the tile pitch and rows for an FB plane, so these helpers can be used both by the normal size calculation and the remapping code. Also add a new fb_plane_view_dims struct in which we can pass around the view (either FB plane or plane source) and tile dimensions conveniently to functions calculating further view parameters. v2: - Add back the +1 tile adjustment for x!=0 in calc_plane_normal_size(). (Ville) - s/pages/tiles/ in calc_plane_normal_size(). (Ville) - Add a helper for the plane view width calculation. (Ville) - Return tiles as unsigned int from calc_plane_normal_size().

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.
