## Installation (Ubuntu)
In the same `linux` folder after compilation, do:
```bash
sudo make modules_install
sudo make install
```
If you are updating Linux on your external USB SSD or you are directly booting into M.2 SSD, i.e. you use `-m2` in `cmdline.txt`, then you have to update the files on the FAT32 partition of your USB drive:
```bash
sudo mv /boot/efi/bzImage /boot/efi/bzImage.old
sudo mv /boot/efi/initrd.img /boot/efi/initrd.img.old
sudo cp /boot/vmlinuz-$(uname -r) /boot/efi/bzImage
sudo cp /boot/initrd.img-$(uname -r) /boot/efi/initrd.img
```
If you are updating Linux on your M.2 SSD, but you do not directly boot into it, i.e. if you use `m2_exec.sh`, then you do need to do this step.
## Compilation and Installation (Arch Linux)
Since Arch Linux is different on how the kernel is built, here are some updated commands for compiling
```bash
git clone https://github.com/ps5-linux/ps5-linux-patches
git clone https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git
cd linux
git checkout tags/v7.0.3
git apply ../ps5-linux-patches/linux.patch
