So the kernel test robot runs igt. I've seen a handful of reports over
the years, but not a whole lot. If you run it even semi-regularly, I
would have expected more. What's the deal here?
There's clearly overlap with what our CI is doing. Maybe better
coordination would be useful? Especially wrt reporting. I'm not sure if
anyone's going to track these mails.

That's six months old and more than 1k commits behind. The results are
going to be useless, I'm afraid.
