**Notes:**
- **VR Support**: Indicates how well supported the necessary Vulkan API components are.
- **Reprojection Support**: Describes the support and quality of reprojection features for VR. Poor support indicates that the driver is not able to properly handle Vulkan realtime shaders and it will present as visual stutter. Non-robust solutions will suffer stutter under very high GPU load.
- **PRIME/ Hybrid GPU Support**: Compatibility with systems using multiple GPUs for render offload. Monado and all clients must be run on a single select GPU due to memory tiling requirements.
- For Nvidia proprietary drivers, the [vulkan-layer](https://gitlab.freedesktop.org/monado/utilities/vulkan-layers) is **required** not to crash.
- AMD GPUs lower than RDNA generation have functional but less robust reprojection capabilities, expected to be similar to Intel.
- Audio over displayport is known to temporarily cut out when new audio sources spring up on pipewire [without a fix to add alsa headroom](https://wiki.archlinux.org/title/PipeWire#Audio_cutting_out_when_multiple_streams_start_playing)
- X11 configurations are discouraged but workable, please upgrade your system to Wayland if at all possible.

## Hardware note

WiVRn PC XR to WiVRn PC client streaming remains mainly for debug use.

Vive Pro microphones should be set to use 44.1khz sample rates as feeding in 48khz raises the pitch of the audio.

Valve index audio output should be set to 48khz or no audio will output.

Vive Pro Eye HMD functional, eyechip WIP.

Pimax initialization code WIP. Distortion matrix dump work in progress.

Eyetrack VR and Project Babble will both be implemented through [oscavmgr](https://github.com/galister/oscavmgr) to emit proper unified flexes over OSC.

## Applying a kernel patch (for Vive Pro 2, Bigscreen Beyond, Pimax)

### Arch

1. download the patch(es), then follow the steps on https://wiki.archlinux.org/title/Kernel/Arch_build_system,
    which should be roughly: `mkdir ~/build/` -> `cd ~/build/` -> `pkgctl repo clone --protocol=https linux` -> `cd linux`
2. (section 2 of link) open `PKGBUILD` in that directory and modify the `pkgbase` line (at the top) to read e.g. "`pkgbase=linux-customvr`". then add a line containing "`<patchfilename>.patch`" to the `source` array:

```pkgbuild
source=(
  https://cdn.kernel.org/pub/linux/kernel/v${pkgver%%.*}.x/${_srcname}.tar.{xz,sign}
  <patchfilename>.patch
  $url/releases/download/$_srctag/linux-$_srctag.patch.zst{,.sig}
  config  # the main kernel config file
)
```

4. close `PKGBUILD`. (may not be necessary but i ran `updpkgsums`) -> `makepkg -s --skippgpcheck` (i didn't feel like fixing a pgp error)
5. then section 4 of https://wiki.archlinux.org/title/Kernel/Arch_build_system#Installing and restart

### NixOS

1. download the patch(es)
2. add this to your configuration.nix or other nix file you use:
```nix
  boot.kernelPatches = [
    {
      name = "type what the patch is for here";
      patch = /path/to/patch/file.patch;
    }
  ];
```
