I've not worked out how to best to use it, other than log it. The choice
is whether to restore to fstart on returning control to the BIOS (i.e.
module unload / intel_rps_disable) which is what we've previously tried.
But what's the point -- we use idle frequency currently, and so is
fstart a better choice for idle frequency (and would that be?) I have
more questions than answers, so left it alone.
