<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>I don't remember what I did on my old i7 to keep it on
performance. One involved having to push the performance setting
to EACH CPU/thread, I think that's covered on that link somewhere.
May have been a script. I don't remember how I did it, but it
stuck between boots. I think I actually tried three different
things, so I really don't know which one did the trick.</p>
<p>I haven't done it on my present i9. Laptops aren't really good
homes for the i9 - needs a whole lot more airflow than a laptop
can provide. Running at 900MHz right now and 115F.<br>

<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>

Don't know about that. Wasn't that something that had to be set in
the kernel at compile time?<br>
