Build fails with sccache.
- Update meson-scripts/build_bpftool to support sccache. Unfortunately, this
isn't enough.
- Update README to warn about sccache and add the instruction to disable it
for buliding scx.
- Also add ⚠️ to make boot loader update step more prominent in arch
installation instruction.

Install Instructions by Distro
Ubuntu
Experimental sched_ext support for Ubuntu is provided by the following launchpad project:
https://launchpad.net/~arighi/+archive/ubuntu/sched-ext
Upgrading to 24.04 (NobleNumbat)
Currently, only the 24.04 release is supported. You can upgrade to 24.04 using the following command:
$ sudo do-release-upgrade -d
Installing the Kernel and Schedulers
$ sudo add-apt-repository -y --enable-source ppa:arighi/sched-ext
$ sudo apt install -y linux-generic-wip scx
$ sudo reboot
After the reboot, the scheduler binaries in /usr/sbin/scx_* should be usable.
Note: they must be called with sudo like other BPF programs e.g. sudo scx_simple.
Setting up Dev Environment
$ apt source scx
$ sudo apt build-dep scx
Arch Linux
Import the gpg key. This can be skipped if the signature checking is disabled.
$ sudo pacman-key --recv-keys F3B607488DB35A47 --keyserver keyserver.ubuntu.com
$ sudo pacman-key --lsign-key F3B607488DB35A47
If you haven't imported the GPG key, append the following line.
SigLevel = Never
Adding the Repository
Install packages with a list of mirrors and GPG keys
$ sudo pacman -U 'https://mirror.cachyos.org/repo/x86_64/cachyos/cachyos-keyring-20240331-1-any.pkg.tar.zst' 'https://mirror.cachyos.org/repo/x86_64/cachyos/cachyos-mirrorlist-18-1-any.pkg.tar.zst'
Add the following custom repository section to /etc/pacman.conf.
# cachyos repos
[cachyos]
Include = /etc/pacman.d/cachyos-mirrorlist
Installing the Kernel and Schedulers
$ sudo pacman -Sy cachyos/linux-sched-ext cachyos/linux-sched-ext-headers cachyos/scx-scheds
⚠️ The kernel installs as /boot/vmlinuz-linux-sched-ext along with
the matching initramfs. Update the bootloader configuration to add the boot
entry for the new kernel.
Setting Up Dev Environment
In addition to the packages from the previous step, install the following.
$ sudo pacman -Sy meson cargo bpf pahole
Fedora
Experimental sched_ext support for Fedora is provided by the following copr project:
https://copr.fedorainfracloud.org/coprs/jordalgo/fedora-6.8-sched_ext/
Installing the Kernel
$ sudo dnf copr enable jordalgo/fedora-6.8-sched_ext
$ sudo dnf --disablerepo="*" --enablerepo="copr:copr.fedorainfracloud.org:jordalgo:fedora-6.8-sched_ext" upgrade kernel
$ sudo reboot
Then select the kernel containing the name "schedext".
Installing the Schedulers
At the moment, only the Rust schedulers are available for install (c schedulers coming soon):
- scx_rusty
- scx_layered
- scx_rustland
Example:
$ sudo dnf install scx_rusty
$ sudo scx_rusty
Setting up Dev Environment
No additional steps needed here other than what is mentioned in the main README.md.
