Hi All,
Here is v2 of my patch series converting the staging atomisp driver to use
the videobuf2 framework, fixing MMAP mode not working.
New in v2 is that the "media: atomisp: Convert to videobuf2" patch
now also contains moving over to using a per vb_queue lock as is
standard for v4l2 drivers. This removes a bunch of FIXME + checkpatch
warnings (due to commented out prep for this) from v1 of this patch.
This v2 also fixes the 1 new warning pointed out by the lkp test robot.
For some more background info here are the still relevant bits of
the v1 cover-letter:
This also contains an important fix to try_fmt handling, so that
the various supported output formats can actually be used by userspace
which calls try_fmt before doing s_fmt.
So slowly this is starting to look more and more like a standard
v4l2 device (with all the complex pipeline handling hidden in the driver,
moving that to userspace seems to be impossible with this design since
multiple pipeline steps are handled by a single firmware program).
Regards,
Hans
