Enable low latency features in the generic Ubuntu kernel for 24.04

Excellent!

@arighi

just to be clear, we are not planning to deprecate the lowlatency kernel for 24.04.

Right, I wouldn’t think this at all. If you were, I’d have expected a lot more heads-up because I’d have some work to do in livecd-rootfs. Like, a lot of work. That said, that was never a concern.

@arighi

For now the main goal of these changes is to make the generic kernel more flexible (aka more “generic”) and potentially make it usable also in certain “low latency” scenarios, considering that, with these changes applied, it would basically provide all the features that lowlatency provides.

This is wonderful, and definitely a welcome endeavour! We have the ubuntustudio-installer package to make Ubuntu Studio’s features installable on any flavor regardless of desktop environment. Having all or most of the lowlatency kernel’s features in the generic kernel is synergic in this endeavor.

@arighi

I’ll take a look at the liquorix kernel, if there’s something interesting we may consider to investigate more / conduct some tests and possibly include it in our kernel as well (either lowlatency or even generic).

Thank you! There must be something here as it’s generally praised throughout the Linux Audio and Gaming communities. I tried it out myself and it honestly saved my ability to do my workshop in Riga while I was preparing for it when the lowlatency kernel had a regression in 23.10 prior to release. Honestly, I was impressed with its performance on my laptop and it didn’t noticeably sacrifice much power, so there must be something to it.
