Here's how to compile and install the fairydust branch of the Asahi Linux kernel, to test out experimental DisplayPort over USB-C support. I wrote this for Gentoo, though it can be adapted for Asahi Fedora Remix, too.
- Clone the sources
git clone -b fairydust --single-branch --depth 1 https://github.com/AsahiLinux/linux.git
cd linux- Read the current kernel config into .config. I recommend updating and booting to the same Linux release that fairydust is based on, in my case 6.18.5.
