This is a moot point. The distintion between the signal and the
interrupt doens't matter here.

I was only asking why the interrupt was optional, and it seems per the
spec it's expected to be handed to an agent at a higher exception level.

That implies that the OS should only care about WS0, assuming that I've
understood correctly.

Thanks,
Mark.
