Split up the connector's mode_valid helper into a simple-pipe and a mode-config helper. The simple-pipe helper tests for display-size limits while the mode-config helper tests for memory-bandwidth limits. Also add the mgag200_ prefix to mga_vga_calculate_mode_bandwidth() and comment on the function's purpose. The memory-bandwidth tests assume that the display uses 4 bytes per pixel. The first models of G200SE-A only had 1.75 MiB of VRAM, which limits these devices to 640x480-32. v2: * note the memory constraints on early G200SE-A Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Jocelyn Falempe <jfalempe@redhat.com> Tested-by: Jocelyn Falempe <jfalempe@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220516134343.6085-8-tzimmermann@suse.de
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.
