I don't see any reason why not, but wanted to ask to make sure: this
daemon can be bound to a core, correct? At least manually by taskset or
similar?
It sounds a lot like the RTAS thread, which I was happy to see go away
when running directly on OPAL, and don't want something else to take its
place. It was not bindable, but ran periodically on EVERY core, err
hardware thread.
(Just looking to avoid latency blips.)
