Add a kmsg option, which will display the last lines of kmsg, and should be similar to fbcon. Add a drm.panic_screen module parameter, so you can choose between the different panic screens available. two options currently, but more will be added later: * "user": a short message telling the user to reboot the machine. * "kmsg": fill the screen with the last lines of kmsg. You can even change it at runtime by writing to /sys/module/drm/parameters/panic_screen v2: * Use module parameter instead of Kconfig choice (Javier Martinez Canillas) v3: * Add help for module parameter usage in Kconfig (Javier Martivez Canillas) * Fix use of font->height before checking it isn't null.

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 reStructuredText 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.
