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
|
|
```
|
|
|
|
:warning: 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. |
