Add support for damage handling and deferred I/O to fbdev-dma. This enables fbdev-dma to support all DMA-memory-based DRM drivers, even such with a dirty callback in their framebuffers. The patch adds the code for deferred I/O and also sets a dedicated helper for struct fb_ops.fb_mmap that support coherent mappings. v3: - init fb_ops with FB_GEN_DEFAULT_DEFERRED_DMAMEM_OPS() (Javier) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Javier Martinez Canillas <javierm@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240419083331.7761-22-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.
