That's great.

Thanks again.

Our kms-tests test suite for verifying the R-Car DU is based on kmsxx.

We are implementing a 'loop-back' validator, by providing an HDMI cable from
the display output directly into the HDMI receiver on the same development
board.

By using the existing VideoStreamer and pyvid objects, we can capture the output
and compare to provide automated display validation.

As an effort to commence this process, this series implements a basic frame
buffer comparison, which expects identical frame sizes to operate.

This could be could be expanded upon later to provide a more detailed
comparison at the pixel level later, but this serves as an initial starting
point to quickly verify if the data captured matches the data that we expected.

   videodevice: Fix minor spacing
   py: pyvid: Provide stream_off binding


Thanks, I've picked up the first two patches.

Hi Tomi,

Apologies that I didn't make it particularly clear, but I should have prefixed
this series title with a nice big [RFC] :-D

This is ongoing work to support loop-back validation on our platforms.

Regards

Kieran
