Actually, TSC on this box should be stable and invariant, so I guess I
can try with the default governor. Will do that on Monday. Does ARM
have frequency scaling (I did remember something on xen-devel, but I am
not sure whether it landed upstream)?
I guess you mean the series sent by globallogic ([1])? If so, it was
never upstreamed.
However the frequency scaling may depend on the processor used and
sometimes implemented using big.LITTLE (e.g the task has to switch).
I am not sure why it would matter in this case.
