I feel like I must be missing something. It looks like this patch accepts a buffer from the user, and stores it. However I don't see how the NPU firmware ever learns that this special buffer exists to then use it.

The debug function is incomplete while I was creating the patch. Thus, I put a line in TODO "Improve debug bo support".

We made progress on this feature. Should I add the code to V4 patch? Or I can add it within future patches.

Discussed this more internally. And we would postpone debug_bo feature. Thus, I will  drop this patch for now.
