This is a driver for multimedia devices based on Techwell/Intersil TW5864 chip.
It is basically written from scratch. There was an awful reference driver for
2.6 kernel, which is nearly million lines of code and requires half a dozen
special userspace libraries, and still
larly contacting manufacturer regarding such issues, but
unfortunately they can do little to help us.

Hi Hans!
Some improvements took place on the driver, including cleaner
v4l2-compliance tests passing. But there's a single test failure I
don't understand.
In the code of v4l2-compliance, it seems like an API
call CREATE_BUFS is supposed to fail with EINVAL. But in case of my
driver, which simply
launch on boot. Rebooted, and the host got down up to now :(
Any comments, except laugh? :)

Without irqbalance daemon, all solo6x10 interrupts are still on CPU0.

Before, it was called from individual encoder (de)init procedures, which
lead to spare threads running (which were actually lost, leaked).
The current fix uses trivial approach, and the downside is that the
processing thread is working always, even when there's no consumer.

I'm working on Linux kernel driver for multimedia grabber and H264
encoder based on Techwell/Intersil 5864 chip. Of course it will be
open and pushed into upstream kernel.
The device produces H264 encoded data, but it lacks any headers. The

Oh hi a linux.org.ru buddy :)
I get headerless binary data portions of known length, one portion for
each encoded video frame. NAL headers generation is done on driver
level in r
variable. So likely the trailing zero is a typo.
