Linux: Renoise creating audio threads on energy-saving cores when limiting realtime audio CPUs

[artfwo]

I’m running Renoise on Linux on an Intel Adler Lake CPU that has performance and energy saving cores. I’m trying to set `Realtime audio CPUs` to 8 to limit the cores used to the first 8 as described here:

Always make sure you only enable as many CPU threads as there are performant (fast) cores in Renoise for Audio. Using low-power cores in mix with fast cores will probably make things worse for real-time audio applications.

But it looks like new audio threads are still created on the energy-saving cores:

❯ ps -T -p $(pgrep renoise) -o tid,psr,comm
    TID PSR COMMAND
 299744  10 renoise
 299749   6 MIDI Input
 299752  12 Script WatchDog
 299753  13 Socket Server
 299759  11 pw-renoise
 299760  15 pw-renoise
 299761  13 data-loop.0
 299762   6 Link Main
 299763   4 Link Dispatcher
 299764  14 Socket Server
 300394  15 Audio Slave 01
 300395  12 Audio Slave 02
 300396   9 Audio Slave 03
 300397  11 Audio Slave 04
 300398   5 Audio Slave 05
 300399   1 Audio Slave 06
 300400   8 Audio Slave 07
 300401   2 Audio Slave 08

Is the linked instruction specific to Apple M1/2? Can I somehow pin audio threads to performance cores on Linux too? Thanks!
