# Stability Matrix on ArchLinux on AMDGPU

## Install dependencies

On ArchLinux `libcrypt.so` is already version 2, so you need to install `libxcrypt-compat`.
`rocblas` is a dependency for running Stable Diffusion.

```
yay -S libxcrypt-compat rocblas
```

## Fix PyTorch installation

To use PyTorch on AMD you need to reinstall it with ROCm support.

```
./Data/Packages/Stable\ Diffusion\ WebUI/venv/bin/pip3 install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/rocm5.4.2 --upgrade --force-reinstall
```

## Make amdgpu.ids reachable

```
sudo mkdir -p /opt/amdgpu/share/libdrm/
sudo ln -s /usr/share/libdrm/amdgpu.ids /opt/amdgpu/share/libdrm/amdgpu.ids
```

## Env variables in Stability Matrix

```
HSA_OVERRIDE_GFX_VERSION = 10.3.0
```

## Additional start options

```
--medvram
--precision full --no-half
```
