Add an fbdev client that can work with any memory manager. The client implementation is the same as existing code in fbdev-dma or fbdev-shmem. Provide struct drm_driver.fbdev_probe for the new client to allocate the surface GEM buffer. The new callback replaces fb_probe of struct drm_fb_helper_funcs, which does the same. To use the new client, DRM drivers set fbdev_probe in their struct drm_driver instance and call drm_fbdev_client_setup(). Probing and creating the fbdev surface buffer is now independent from the other operations in struct drm_fb_helper. For the pixel format, the fbdev client either uses a specified format, the value in preferred_depth or 32-bit RGB. v2: - test for struct drm_fb_helper.funcs for NULL (Sui) - respect struct drm_mode_config.preferred_depth for default format Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240924071734.98201-4-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 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.
