Thank you for working on this! It's much appreciated. Now I've

noticed that

patches regarding memory-to-memory and memory pool tend to get

very few comments.

I suspect that the main reason is that these are SoC-specific

features that do

not occur in consumer-type products. So most v4l developers do not

have the

interest and motivation (and time!) to look into this.

Thank you very much for your response. We were a bit surprised with
the lack of
responses as there seemed to be a good number of people interested
in this area.

I'm hoping that everybody interested would take a look at the test
device posted
along with the patches. It's virtual, no specific hardware required,
but it
demonstrates the concepts behind the framework, including
transactions.

[Hiremath, Vaibhav] I was on vacation and resumed today itself, I will go through these patch series this weekend and will get back to you.

I just had cursory look and I would say it should be really good starting point for us to support mem-to-mem devices.\

Hmm... it seems to me that those patches are still under discussion/analysis.
I'll mark them as RFC at the Patchwork.

Please let me know after you, SoC guys, go into a consensus about it. Then,
please submit me the final version.

Cheers,
Mauro
