By putting cursor BOs at the high end of the video memory, we can avoid memory fragmentation. Starting at the low end, contiguous video memory is available for framebuffers. The patch also simplifies the buffer swapping by splitting struct ast_private.cursor_cache BO into two separate boffer objects. Cursor images alternate between these buffers instead of offsets within cursor_cache. v3: * fixes space-before-tab error near AST_HWC_SIGNATURE_CHECKSUM Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Acked-by: Gerd Hoffmann <kraxel@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190927090309.10254-6-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.
