resetting the idle rate counter does not work.
Is results in an idle rate of 99%

Without looking in the code I think it just resets the accumulated computation time (t_{comp}) while not changing the accumulated total time (t_{tot}.
idle-rate = i_r = 1 -(t_{comp}/t_{tot}.

To have a working reset function would help a lot looking inside special kernels to see whats going on in a specific part of the code.
A start, stop function for the time messing would work I think.

I hope there is no other counter providing this functionality I didn't saw.

I think this does not fixes the problem.
I get a negative idle rate now:
threads{locality#0/total}/idle-rate,1,5.836486,[s],-3.93669e+07,[0.01%]
