Alright everyone, get your fancy kernel schedulers here. This has been shipping with Bazzite for a while (they default to `scx_lavd` on handhelds.)

This will only be available in the `latest` channel for the time being. If this lands in the upstream 6.12 kernel as people expect then it’ll come to the other channels eventually… If you’re on Nvidia then some of the builds aren’t building tonight, so if you don’t have this in your daily build then it means you failed the saving throw for the day. The Nvidia skew usually clears up in a few days. It’s up to you to pick the scheduler and set up the system service, follow the docs below for more info.

I’m currently testing out `bpfland` on my system. Thanks to the [CachyOS](https://cachyos.org/) folks for providing awesome docs and development in this area!

Ok, this is landing in 6.12 so we’ve dipped our toes enough for now, we’re buckling down for F41 release so this experiment is over, we’ll reinvestigate schedulers when all of this lands in the vanilla kernel:

> NOTE: This is for folks who are on bluefin:latest. You are only using this if you opted in and rebased to it or if we had to put you there for hardware reasons. Most of you can ignore this. Since sched\_ext is scheduled to land in 6.12 and we likely have to keep Surface and Asus images around anyway we’re going to go ahead and switch the :latest branch back to the vanilla kernel. We want to do this now so we can move to it now ahead of F41’s release. We’ll reinvestigate scheduler goodies in the…
