Abstract the framebuffer details by mappings its BOs with a call to drm_gem_fb_vmap(). Unmap with drm_gem_fb_vunamp(). Before, the output address with stored as raw pointer in the priv field of struct drm_writeback_job. Introduce the new type struct vkms_writeback_job, which holds the output mappings addresses while the writeback job is active. The patchset also cleans up some internal casting an setup of the output addresses. No functional changes. v3: * free instances of struct vkms_writeback_job on cleanup or errors Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Rodrigo Siqueira <Rodrigo.Siqueira@amd.com> Acked-by: Sam Ravnborg <sam@ravnborg.org> Link: https://patchwork.freedesktop.org/patch/msgid/20210730183511.20080-6-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.
