How to use legacy OpenCL in amdgpu without using DKMS on Pop OS 22.04? (reddthat.com)

I have a pretty old laptop with an AMD dGPU and I am trying to do OpenCL compute on it to make sure that device switching is handled correctly in some stuff I am testing. All the instructions I see to install amdgpu drivers is to have --no-dkms as an install flag. Doing amdgpu-install --usecase=opencl --no-dkms --opencl=legacy results in ERROR: using '--no-dkms' with '--opencl=legacy' is not supported

Specs:

HP Pavilion 15-br158cl

CPU: i7-8550u (HD 620 iGPU and this has working compute)

GPU: Radeon 530 2 GB DDR3

RAM: 24 GB

OS: PopOS 22.04 6.12.10-76061203-generic

Clinfo -l output

Platform #0: Intel(R) OpenCL HD Graphics
 -- Device #0: Intel(R) UHD Graphics 620 [0x5917]
Platform #1: AMD Accelerated Parallel Processing

As you can see, only the platform, not a second device. Is there anything that I am missing?

I did post this on reddit in the PopOS subreddit. https://www.reddit.com/r/pop_os/comments/1kvza44/is_there_a_way_to_use_amdgpudkms_without_bricking/

IDK what did you mean by "their own thing". Even if they created something similar to dkms, it is unlikely that it would conflict with dkms. But anyway it is better to find more information from official source.

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
