I get around that by using Liquorix kernel which I think is hard coded
to use performance governor. The wiki doesn't mention what to do if
scaling driver is intel_pstate although from reading it's possible to
disable that and load acpi-cpufreq scaling driver instead which is
needed to be able to set the governor to performance AFAIK. There are
several pertinent questions on StackOverflow discussing that, like -
https://stackoverflow.com/questions/53349933/specify-cpu-frequency-as-a-kernel-cmd-line-parameter-of-linux-on-boot/53356512

Back to HW timers, it's trivial to set them as explained in the wiki,
but I'm just wondering if they are actually still used?
