The hardware needs a FB which is packed. Add checks to make sure this is the case. While at it, add debug logs for the existing checks. This allows user-space to more easily figure out why a configuration is rejected. v2: - Use drm_format_info instead of hardcoding bytes-per-pixel (Ilia) - Remove unnecessary size check (Ilia) v3: - Add missing newlines in debug messages (Lyude) - Use NV_ATOMIC (Lyude) - Add missing debug log for invalid format (Ilia) v4: add plane name in debug messages (Ilia) Signed-off-by: Simon Ser <contact@emersion.fr> Reviewed-by: Lyude Paul <lyude@redhat.com> Reviewed-by: Ilia Mirkin <imirkin@alum.mit.edu> Cc: Ben Skeggs <bskeggs@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20210205224140.28174-1-contact@emersion.fr
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.
