The wiki guide at <a

am unsure whether they are still applicable, including the

<p>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 -

<p>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?<br>
