Many of us had amdgpu and want to utilize the OpenCL support of it, but sadly installing rocm is not as straight forward as it should be, and only recently ubuntu jammy supported officially. There is many custom work that modify .deb packages to resolve crazy dependency hell. Im following amd rocm install guide, you may want to look around that web if you are not using ubuntu, in this post i will simplify the guide to ubuntu only.

Prerequisites

• Ubuntu 22.04
• wget
• Time
• Enough space for installation, will need around 2GB space

Installing ROCm

1. Get amdgpu-install scripts

   $ wget https://repo.radeon.com/amdgpu-install/5.3/ubuntu/jammy/amdgpu-install_5.3.50300-1_all.deb
   $ sudo apt install amdgpu-install_5.3.50300-1_all.deb

   This may change if new version released keep watching amd rocm install guide

2. Setup rocm repo for ubuntu jammy

   $ wget -q -O - https://repo.radeon.com/rocm/rocm.gpg.key | sudo apt-key add -
   $ echo 'deb [arch=amd64] https://repo.radeon.com/amdgpu/5.3/ubuntu jammy main' | sudo tee /etc/apt/sources.list.d/amdgpu.list

   Check available version https://repo.radeon.com/rocm/apt/ , ubuntu jammy supported from 5.3.0 + only. To change version replace the 5.3 to another number, ex: 5.3.1

3. Install kernel headers

   $ sudo apt install linux-headers-`uname -r` linux-modules-extra-`uname -r`

4. Install the rocm

   $ sudo amdgpu-install --usecase=rocm --rocmrelease=5.3.0

   This gonna take a while, take a coffee

   Installing different version available by replace --rocmrelease=5.3.0 to some other number, ex: --rocmrelease=5.3.1

5. Install rocm clinfo

   $ sudo amdgpu-install --usecase=opencl --rocmrelease=5.3.0

   If already had clinfo installed please remove it, as normal clinfo will not see ROCm status.

6. Add yourself to video and render group

   usermod -aG render your-username
   usermod -aG video your-username

A simple reboot.

Checking rocm installation, by using clinfo or specifically at /opt/rocm-5.3.0/opencl/bin/clinfo command you can see that OpenCL already enabled.
