Platform devices might operate on firmware framebuffers, such as VESA or EFI. Before a native driver for the graphics hardware can take over the device, it has to remove any platform driver that operates on the firmware framebuffer. Aperture helpers provide the infrastructure for native drivers to remove the generic ones. For now, this only concerns generic fbdev drivers. Code for removing these is provided by drm_fb_helper_remove_conflicting_framebuffers() et al. Simply wrap these functions for now. At a later point, code can be added for generic DRM drivers to acquire firmware framebuffers. v2: * fix docs for drm_aperture_remove_framebuffers() Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Acked-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210412131043.5787-2-tzimmermann@suse.de |

README
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.
