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. 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).

I suppose it is.
Alternatively
cd /tmp/
git clone git://rg42.org/jackfreqd
cd jackfreq/tools
gcc -o busyjack busyjack.c -ljack
./busyjack 60
