struct gtt_range represents a GEM object and should not be used for GTT setup. Change psb_gtt_insert() and psb_gtt_remove() to receive all necessary parameters from their caller. This also eliminates possible failure from psb_gtt_insert(). There's one exception in psb_gtt_restore(), which requires an upcast from struct resource to struct gtt_range when restoring the GTT after hibernation. A possible solution would track the GEM objects that need restoration separately from the GTT resource. Rename the functions to psb_gtt_insert_pages() and psb_gtt_remove_pages() to reflect their similarity to MMU interfaces. v3: * restore the comments about locking rules (Patrik) Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Acked-by: Patrik Jakobsson <patrik.r.jakobsson@gmail.com> Link: https://patchwork.freedesktop.org/patch/msgid/20211015084053.13708-10-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.
