Hantro G2 post processor is able to down scale decoded frames by a factor of 2, 4 or 8. Add enum_framesizes() ops to postproc_ops structure to enumerate the possible output sizes for a given input resolution. For G2 post-processor use fsize->index (from 0 to 3) as power of 2 divisor. As described in v4l2 documentation return -EINVAL when scaling down isn't possible. fluster scores: 77/147 for HEVC 143/303 for VP9 Signed-off-by: Benjamin Gaignard <benjamin.gaignard@collabora.com> Signed-off-by: Hans Verkuil <hverkuil-cisco@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@kernel.org>
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.
