The cursor handling in mgag200 is complicated to understand. It touches a number of different BOs, but doesn't really use all of them. Rewriting the cursor update reduces the amount of cursor state. There are two BOs for double-buffered HW updates. The source BO updates the one that is currently not displayed and then switches buffers. Explicit BO locking has been removed from the code. BOs are simply pinned and unpinned in video RAM. v2: * pin cursor BOs to current location Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Acked-by: Gerd Hoffmann <kraxel@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190613073041.29350-8-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.
