So maybe you know about https://asahilinux.org/, if not, it’s Fedora for m series Mac’s. But when i tried to get ollama to run on it, i got it told me WARNING: No NVIDIA GPU detected. Ollama will run in CPU-only mode, i know fixing this would only be a fix for such a small amount of people but i would highly appreciate it.

There are no Drivers for Apple Silicon GPU in Linux yet to do GPGPU. This have nothing to do with Ollama.

@maxiwee69 as it's not a issue in Ollama, could you please close the Issue?

But just a question, will gpu support be implemented once the drivers are supporting GPGPU?

@maxiwee69 if the GPU is visible to Ollama it will be used. On mac m1, the GPU and CPU memory are shared.

It sounds like a problem with ollama if it is looking for an Nvidia GPU on an Apple system (and potentially PC) when there maybe compute-capable GPUs of other brands.

@karatekid430 I don't see any problems on macOS, except when the memory is not sufficient for the LLM to run on the GPU. I don't use Unix or Windows. I read that with Windows, you need to have the correct driver for the Nvidia card and that the driver needs to be installed manually. Some users don't keep their drivers up to date, which can cause issues.

There is no reason on a hardware level that this shouldn't work. It's the same machine. So its either an Asahi problem or an Ollama problem. At some point, somewhere, the internal GPU is not being advertised.

Running ollama on my mac partition is blazzingly fast (32core GPU), but on the asahi partition, it's an agonizing word ... by ... word affaire :(

For anyone else in the same boat (likely repurposing an old Mac M1/M2 as a dev/home lab server), I found a solution - ramalama and it’s/podman's GPU support on Asahi Linux.

See comments here to get DeepSeek-R1 with GPU support on Asahi Linux (Ubuntu Asahi 24.04 server in my case) working:

Im able to run ollama on asahi linux (Mac Studio with 64 GB of ram).

sudo ramalama --debug --engine docker serve -c 0 -n agi -p 1234 --runtime-args="--flash-attn --mlock" -d gemma3:27b

Shared memory here is showing 32GB however the Mac Studio I have has 64GB of memory. On Mac OS I can utilise all of this for models with apps like LM Studio.

Is this a linux config issue? Is there another way to give ollama access to all of the memory?

I think this is preventing me from loading some models. Without adding --flash-attn the 27b gemma model doesnt load.

I was able to solve this by setting an environment variable which seems to play with the vulkan memory configuration allowing me to increase the shared memory size. So my problem is solved.
