[LAU] Discussion: Future CPU-technology vs. realtime audio?

[Michael Jarosch]

Hi!

Yesterday, I read an article on golem.de 
(https://www.golem.de/news/ryzen-mobile-5000-cezanne-ist-modular-und-sparsam-2101-153653.html) 
about the future of ryzen (mobile) processors from AMD. Inside the 
article, it was told that energy saving is done by the processor itself 
and that the OS will have nothing to do with it.

Using realtime apps, I wrote in the comments that I'd really prefer the 
possibility for userspace interaction and criticized my Intel core i3 
8100 not to allow the user to switch to firm frequencies. It was 
answered that this seems to be the future and that in case of doubt I 
could switch off frequency scaling in the BIOS.

That would mean a lack of comfort to me, as I can't certainly tell, if I 
am using my machine for audio or another task at the moment of powering on.

As soon as frequency switching was introduced we LAU were told, not to 
use it to save xruns. And as far as I can tell, the rule still valid. Is 
there a chance in the future that we can stop thinking about it, because 
it just won't matter? Are we forced blowing loads of energy or do we 
spent too much time in sluggish UEFI menus?

I'd really like to hear your opinion about it (and possible solutions, too)!

Greets!
