Can you use rtas_busy_delay() ?Wasn't aware of that, makes life a lot easier. Do you know if the 0.2s maximum delay also applies across the board? I definitely want to enforce it here, but if it is ubiquitous then it should be in rtas_busy_delay.Not sure sorry, you'll have to read PAPR :)
It doesn't mention anything, but I was more concerned about whether it's ever sensible to have that much of a sleep in any case. Probably safe to ignore given it hasn't been a problem up to this point.
