Hi Robin,

I installed your jackfreqd tool on Debian, via the deb package.
Do I have to do more to make this tool running properly?
no and yes.

No, the tool works OOTB.
Does the tool needs cpufrequtils?
You can verify it by running e.g.
     jack_cpu -c 60 # generate 60% JACK-DSP load
jack_cpu , is that a jack2 only tool? I don't have it here.
Check the JACK-load with `jack_cpu_load` or qjackctl.
To verify that frequency scaling works: Looking at GNOME
CPU-Freq-Scaling-Monitor (or similar) is the easiest way; otherwise:
     sudo watch cat /sys/devices/system/cpu/cpu*/cpufreq/cpuinfo_cur_freq

..and..
Yes, because you may need to disable bus-frequency scaling and PCI
power-saving in the BIOS. (here's what it says here, but your BIOS may
differ: C1E halt state disabled,  EIST disabled,  Turbo disabled).
