Don't add a mode for the kernel's command-line parameters from within the DRM client code. Doing so can result in an unusable display. If there's no compatible command-line mode, the client will use one of the connector's preferred modes. All mode creation and validation has to be performed by the connector. When clients run, the connector's fill_modes callback has already processed the kernel parameters and validated each mode before adding it. The connector's mode list does not contain invalid modes. v2: * grammar in commit message (Javier) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Reviewed-by: Maxime Ripard <maxime@cerno.tech> Link: https://patchwork.freedesktop.org/patch/msgid/20220511183125.14294-4-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.
