Also given Tvrtko's stats, this could all be done from userspace with an

You mean patching and recompiling userspace? I don't think that would
work for them.
No. I was thinking about some proof-of-concept userspace daemon using
per-context stats and tuning each context from a timer. Almost exactly
as proposed here, but it would be very nice validation that our kernel
API are not getting in the way of userspace creativity. :)
But who am I to talk, I think C is a scripting language ;)
Ah, I overlooked you wrote _extended_ CONTEXT_PARAM_SSEU.
