Linux with VIVE Pro 2 patches

Kernel patches created by CertainLach.

NOTE: The custom kernel is only designed to be installed on Arch Linux.
If you are on another distribution, will have to find out how to patch and compile a kernel on it (see CertainLach's repository).
I personally do not recommend using anything else than a bleeding edge distro for this at the moment.
See Kernel Patches section below for the patches used in this guide.

Enter the kernel directory

• cd kernel/

Build and install the patched kernel

• Kernel version: 6.7.arch1-1

Import GPG keys

• for key in ./keys/pgp/*.asc; do gpg --import $key; done

Build the custom kernel

• export MAKEFLAGS="-j $(nproc)"
• makepkg -sc

Install the custom kernel and update the bootloader (e.g. GRUB)

• makepkg -si
• sudo grub-mkconfig -o /boot/grub/grub.cfg

Reboot and ensure you've booted with the patched kernel

• uname -r should print 6.x.x-arch1-1-vivepro2
• You can now proceed with setting up SteamVR and/or the FOSS VR alternatives.
