Hi Songjun,

Before this driver can be accepted it has to pass the v4l2-compliance test.
The v4l2-compliance utility is here:

git://linuxtv.org/v4l-utils.git

Compile the utility straight from this repository so you're up to date.

First fix any failures you get when running 'v4l2-compliance', then do the
same when running 'v4l2-compliance -s' (now it is streaming as well) and
finally when running 'v4l2-compliance -f' (streaming and testing all available
formats).

I would like to see the output of 'v4l2-compliance -f' as part of the cover
letter of the next patch series.

Looking at the code I see that it will definitely fail a few tests :-)

Certainly the VIDIOC_CREATE_BUFS support in the queue_setup function is missing.
Read the comments for queue_setup in videobuf2-core.h for more information.

Regards,

	Hans

Thank you very much, I will pass the v4l2-compliance test before I send 
the version 2 patch.
