Setting up Davinci Resolve on nixos with Rocm and OpenCL

19 April 2024

Introduction

This was only tested on my own GPU(RX 580)
Basic Nixos know-how is assumed

Note for people running Tmpfs-on-root: Building resolve will probably fail, make sure /tmp has enough space if you get an error

Installation

Add it to environment.systemPackages

environment.systemPackages = [
  pkgs.davinci-resolve
];

Now rebuild your system, this will take some time as its a big package

Setting up Rocm OpenCL

  # Enable openGL and install Rocm
  hardware.opengl = {
    enable = true;
    driSupport = true;
    driSupport32Bit = true;
    extraPackages = with pkgs; [
      rocmPackages_5.clr.icd
      rocmPackages_5.clr
      rocmPackages_5.rocminfo
      rocmPackages_5.rocm-runtime
    ];
  };
  # This is necesery because many programs hard-code the path to hip
  systemd.tmpfiles.rules = [
    "L+    /opt/rocm/hip   -    -    -     -    ${pkgs.rocmPackages_5.clr}"
  ];
  environment.variables = {
    # As of ROCm 4.5, AMD has disabled OpenCL on Polaris based cards. So this is needed if you have a 500 series card. 
    ROC_ENABLE_PRE_VEGA = "1";
  };

Rebuild and reboot

sudo nixos-rebuild boot
reboot

Running it

davinci-resolve

Now this should hopefully detect your GPU and run
