[+cc Ben, Logan] Ben, Logan, since you're looking at the resource code, maybe you'd be interested in this as well?

Thanks for rebasing these. They do apply cleanly, but they seem to be base64-encoded MIME attachments, and I don't know how to make mutt extract them easily. I had to save each patch attachment individually, apply it, insert the commit log manually, etc. Is there any chance you could send the next series as plain-text patches? That would be a lot easier for me. > Anybody interested in testing, you can do so with: > > a) Intel system with Thunderbolt 3 and native enumeration.
