In this article, we will guide you through the process of enabling OpenCL on an AMD GPU in Ubuntu 22.04 LTS without proprietary drivers. We will cover different methods, explain the commands used, and provide additional resources for further understanding.
Enabling OpenCL on an AMD GPU in Ubuntu 22.04 LTS without proprietary drivers is possible by using AMD’s ROCm component or the open-source stack. Alternatively, you can try using Radeon Software for Linux version 22.40.3, which has preview support for Ubuntu 22.04.
Understanding OpenCL and AMD GPU
OpenCL (Open Computing Language) is a framework that allows writing programs that execute across heterogeneous platforms. It’s widely used in applications that require high-performance computing.
AMD GPUs are well-known for their compatibility with OpenCL. However, enabling OpenCL can sometimes be a challenge, especially without proprietary drivers.
Method 1: Using AMD’s ROCm Component
While AMD officially supports only Ubuntu 18.04.5(6) and 20.04.4 with their proprietary driver, you can try installing the ROCm (Radeon Open Compute) component of AMD’s proprietary driver. ROCm is an open software platform for GPU-enabled HPC computing.
To install ROCm, use the following command:
sudo apt install rocm-dkms
sudo is used to run the command with root permissions,
apt is the package handling utility in Ubuntu,
install is the command to install a package, and
rocm-dkms is the package name.
Once installed, you need to add ROCm to the PATH. You can do it with the following command:
echo 'export PATH=$PATH:/opt/rocm/bin:/opt/rocm/profiler/bin:/opt/rocm/opencl/bin' | sudo tee -a /etc/profile.d/rocm.sh
This command adds the paths to the ROCm binaries to your system’s PATH variable.
tee -a is used to append the output to a file.
Method 2: Using Open Source Stack
You can also try using the open-source stack to enable OpenCL on your AMD GPU. To do this, install the latest AMD driver. As an example, we’ll use version 21.50:
amdgpu-install --usecase=opencl --no-dkms
amdgpu-install is the command to install the AMD GPU driver,
--usecase=opencl specifies that we’re installing the driver for OpenCL use, and
--no-dkms means we’re not using the Dynamic Kernel Module Support (DKMS) method for installation.
Please note that this solution might cause issues with the gnome-control-center, so proceed with caution.
Method 3: Using Radeon Software for Linux
Radeon Software for Linux version 22.40.3 was released with preview support for Ubuntu 22.04. This version may provide the necessary OpenCL functionality for your AMD GPU.
You can download it from the official AMD website.
Enabling OpenCL on an AMD GPU in Ubuntu 22.04 LTS without proprietary drivers can be a bit tricky, but it’s certainly possible. We’ve covered a few methods in this article, but remember to thoroughly research and test these options before making any changes to your system. Always back up your data before making significant changes to your system configuration.
Yes, it is possible to enable OpenCL on an AMD GPU in Ubuntu 22.04 LTS without proprietary drivers. We have provided several methods in this article to help you achieve it.
OpenCL (Open Computing Language) is a framework that allows writing programs that execute across heterogeneous platforms. It is widely used in applications that require high-performance computing.
Proprietary drivers are software drivers that are developed and distributed by the hardware manufacturer. They are designed specifically for their hardware and often provide better performance and compatibility compared to open-source drivers.
ROCm (Radeon Open Compute) is an open software platform for GPU-enabled HPC computing. It is developed by AMD and provides a set of tools and libraries for high-performance computing tasks.
The open-source stack refers to the collection of open-source software components that are used to enable and support various functionalities on a system. In the context of enabling OpenCL on an AMD GPU, it involves using open-source drivers and tools instead of proprietary ones.
Yes, you can try using the open-source stack to enable OpenCL on your AMD GPU. It involves installing the latest AMD driver and configuring it for OpenCL use. However, please note that this solution may cause issues with the gnome-control-center, so proceed with caution.
You can download Radeon Software for Linux from the official AMD website. Visit their support page and look for the appropriate version compatible with Ubuntu 22.04 LTS.
Yes, it is always recommended to backup your data before making any changes to your system configuration. This ensures that you can restore your data if any issues arise during the process.
