With the new prepare_streaming op it is possible to move the ugly v4l_vb2q_enable_media_source() call in vb2_core_streamon to the driver. It was called incorrectly in vb2 as well: it was only called if sufficient buffers were queued at STREAMON time, but not if more buffers were queued later. This was not an issue with the au0828 driver since it never set min_buffers_needed. 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.
