As i stated, the driver is still in an early development stage, it
doesn't do anything useful yet. But this is the public git repository
if you want to take a look:

git repo: https://github.com/jmartinc/video_visstrim.git
branch: ?mx27-codadx6

Thanks, I will take a look at your tree when I am back to the office next week.

I also see that Linaro's tree has support for VPU for mx5/mx6:
http://git.linaro.org/gitweb?p=landing-teams/working/freescale/kernel.git;a=summary

,so we should probably think in unifying it with mx27 support there too.

FYI we are only interested on adding support for the encoding path of
the VPU, but we are trying our best to make it modular (as it is done
in Samsung's [1]), so that anyone can add decoding support later.

Ok, sounds good.

By the way, you work for Freescale, don't you?

Yes, correct.

We have a couple of issues with the i.MX27 VPU:

1- Firmware for the VPU is provided as a table of binary values inside
a source file which is licensed as GPL, however software is packaged
in a .tar.gz file that is marked as NDA. Do we have the right to
distribute this firmware with our products?

To address this issue it would be great if you, as a Freescale
employee, could send VPU firmware binary file to linux-firmware with a
LICENSE.xxxx file as well:

http://git.kernel.org/?p=linux/kernel/git/dwmw2/linux-firmware.git;a=tree

quoted

2- There is a BUG in the firmware that marks P frames as IDR when it
should only be done to I frames. Would it be possible to have access
to the source code of the firmware in order to fix that problem?

I will need to check this next week when I am back to the office.

Regards.
