Current update area calculation is not handling situation where e.g. cursor plane is fully or partially outside pipe area. Fix this by checking damage area against pipe_src area using drm_rect_intersect. v2: Set x1 and x2 in damaged_area initialization v3: Move drm_rect_intersect into clip_area_update v4: draw_area -> pipe_src Closes: https://gitlab.freedesktop.org/drm/intel/-/issues/5440 Cc: José Roberto de Souza <jose.souza@intel.com> Cc: Mika Kahola <mika.kahola@intel.com> Reviewed-by: José Roberto de Souza <jose.souza@intel.com> Signed-off-by: Jouni Högander <jouni.hogander@intel.com> Signed-off-by: José Roberto de Souza <jose.souza@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220513142811.779331-3-jouni.hogander@intel.com
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.
