Framebuffer devices that are registered by DRM drivers for fbdev emulation have a "drmfb" suffix in their name. But makes them to be quite confusing for drivers that already have "drm" in their name: $ cat /proc/fb 0 rockchipdrmdrmfb $ cat /proc/fb 0 simpledrmdrmfb Also, there isn't a lot of value in adding these "drmfb" suffices to their names, since users shouldn't really care if the FB devices were registered by a real fbdev driver or a DRM driver using the fbdev emulation. What programs should be interested about is if there's a DRM device, and there are better ways to query that info than reading this procfs entry. So let's just remove the suffix, which leads to much better device names: $ cat /proc/fb 0 rockchipdrm $ cat /proc/fb 0 simpledrm Suggested-by: Thomas Zimmermann <tzimmermann@suse.de> Signed-off-by: Javier Martinez Canillas <javierm@redhat.com> Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Link: https://patchwork.freedesktop.org/patch/msgid/20210525151313.3379622-1-javierm@redhat.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.
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.
