    <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>
