Use the shadow plane helper to take care of mapping the framebuffer for CPU access. The synchronous flushing is now done inline without the use of a worker. The async path now uses a shadow buffer to hold framebuffer changes and it doesn't read the framebuffer behind userspace's back anymore. v2: - Use src as variable name for iosys_map (Thomas) - Prepare imported buffer for CPU access in the driver (Thomas) Reviewed-by: Thomas Zimmermann <tzimmermann@suse.de> Signed-off-by: Noralf Trønnes <noralf@tronnes.org> Link: https://patchwork.freedesktop.org/patch/msgid/20221122-gud-shadow-plane-v2-5-435037990a83@tronnes.org |

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.
