I'm just experimenting with new setups of Debian for audio. When running

discussion (here?) that configuring hpet and rtc timers is no longer
necessary as they are not used any more. Is this true or am I
misremembering?
The wiki guide at https://wiki.linuxaudio.org/wiki/system_configuration
is still a goldmine for setup but it contains some sections of which I
am unsure whether they are still applicable, including the HW timers bit.
Hmm...doing similar, but, I can't get the cpu frequency to stay set between boots...
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?
