T2-Gentoo-Kernel
Linux Kernels for Gentoo customized to support T2 Macs
This branch has been deprecated. Please checkout the Mainline or LTS branches.
Installing from CI packages
Download the files from the latest release. You should have two tar files called linux-[VERSION]-t2-img.tar.xz and linux-[VERSION]-t2-src.tar.xz.
Extract both tar archives and go into the build folder from those tar archives.
Copy the files from the boot folder to /boot.
Copy the files from the lib/lib/modules folder to /lib.
Copy the files from the usr folder to /usr.
You can now delete the build folders and the tar archives.
Building manually
Before we start, these scripts are intended to be run in a chroot environment where the user is signed in as root. If you cannot log in as root but you have access to sudo, then run the commands in sudo -s shell or use the prefix sudo bash before running each script.
If you want to build a kernel yourself, then git clone this repo somewhere on your Linux install. Make sure you have these packages installed:
bc kmod pahole cpio perl git curl
MAKE SURE TO EMERGE kmod WITH THE zstd USE FLAG
First make sure that you can run all of the programs by running chmod +x prepare.sh build.sh install.sh package.sh.
Now run prepare.sh and let the script run. If you stopped the script, then you'll have to delete all of the files the script made before and try again.
If you would like to configure the Linux kernel to your liking, then run the following commands:
cd linux-t2
make menuconfigYou're now ready to build the kernel. Run build.sh and let the script run. If you stopped the script, then you can run it again and it will continue where it left off.
If you would like to install the kernel, run install.sh. If you want to instead package up the kernel for someone else, then run package.sh.
If you installed the kernel instead of packaging it, then some programs you install might require the Linux Kernel source code. Run this to fix that issue:
cp linux-t2 /usr/src/linux-[INSERT KERNEL VERSION HERE]
eselect kernel list # you should see your kernel version pop up, note down the index number
eselect kernel set [INDEX]
