Now, what this means is you can boot this kernel, then just start the scheduler from userland, e.g.
run0 scx_rustland
It uses bpf, so the scheduler switches immediately and is as fast as anything in the kernel space. What makes this rustland scheduler super interesting is how it can detect what application is currently active, and give it a full priority over anything else. So you can compile code in the background with all cores, and at the same time play a game with the best frame rate.
There are other sched_ext schedulers available, at least on nixos with the cachyos kernel I get a bunch of scx_ binaries to play with.
For nix users here, nyx flake packages and compiles the cachyos kernel:
Oh hell no why the actual fuck does systemd attempt to replace every single component of the Linux stack? We don’t need more of this monolithic bullshit. What’s next, replace the Linux kernel with systemd? Fucking hell. And why the hell did they give it such a stupid name??? run0? The only way this makes sense, is because 0 people should actually run this on their god damn system. I’m just waiting for applications to start breaking because some stupid systemd dependency, which itself depends on 15 gigabytes of other systemd bloat isn’t installed.
Sorry for the rant
I’ll definitely stay on Gentoo with doas and OpenRC

Thanks for sparking my interest on cachyos kernels and what they patch. In addition to bore, they also patch the sched_ext support!

Wtf is run0
Edit: Is that nyx flake made by the same guys as the Chaotic AUR repo for arch?

Looks like it if you check from GitHub.

I’m too old to rant about systemd :D
