Low latency Kernel

hdansin

Greetings,

As I use Solus for recording music, I was wondering if it would be possible to use/enable a low latency kernel. I've set up Jack, but I still notice enough latency to bother me when recording and monitoring with Ardour. I was reading about AVLinux and the Liquorix Kernel, and I believe Ubuntu Studio/Fedora Jam might do something with the Kernel to get lower latency. I am somewhat ignorant of what goes into installing different kernels, but it would be really great for creators to have a sort of AV Solus, if not an edition, at least the ability to get lower latency. If there's any way I could contribute to something like this, let me know.

This is how to enable low-latency kernel in Solus:
Add 3 kernel parameters (preempt=full, threadirqs, mitigations=off) to a configuration file;

create directory sudo mkdir -p /etc/kernel/cmdline.d
create configuration file echo 'preempt=full threadirqs mitigations=off' | sudo tee /etc/kernel/cmdline.d/lowlatency.conf
apply these changes to clr-boot-manager sudo clr-boot-manager update

And reboot ...I think
PS. you can leave out mitigations=off, if you are concerned about spectre meltdown vulnerability. But there's possible CPU performance penalty with mitigations ON. My opinion, and how I set it, it's always OFF.

qk4-li3 Thanks, I'll give this a try when I get some time.
