Replace vkms' prepare_fb and cleanup_fb functions with the generic code for shadow-buffered planes. No functional changes. This change also fixes a problem where IGT kms_flip tests would create a segmentation fault within vkms. The driver's prepare_fb function did not report an error if a BO's vmap operation failed. The kernel later tried to operate on the non-mapped memory areas. The shared shadow-plane helpers handle errors correctly, so that the driver now avoids the segmantation fault. v2: * include paragraph about IGT tests in commit message (Melissa) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Melissa Wen <melissa.srw@gmail.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210705074633.9425-4-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 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.
