Stolen and degraded time and schedulers
...l. (This is the instance where the worst kind of tsc -
varying speed which stops on idle - is actually exactly what you want.)
You could also measure "work units" in terms of normalized time units:
if the fastest CPU on the machine is 2.4GHz, then 1ms is 1ms a work unit
on that CPU, but 250us on the 600MHz CPU.
It doesn't really matter what the unit is, so long as it is used
consistently to measure how much progress all processes made.
So, how to implement this?
One quick hack would be to just make a new clocksource entrypoint, which
returns work units rather than real-time cycl...
