ollama running on amd 8840HS

So, shiny new lenovo with a 8840HS CPU rocking the 780M (A)GPU

💡

Installing Ollama was straight forward. Pulling models, also very easy. Understanding why the (A)GPU was ignored - a bit more cumbersome.

This was performed on a lenovo P14s 5Gen AMD 8840HS with 32GB memory running Fedora Workstation 41

Let’s start with the obvious stuff. The latest GPU firmware must be installed and the latest version of ollama must also be installed. As of this writing it is ollama 0.4.6

Then you may, or you may not, want to up the dedicated amount of “VRAM” your (A)GPU is allowed to use. My, albeit limited, experience is that leaving it at AUTOMATIC will send 50% of the processing to the CPU and 50% to the (A)GPU when working with models around ~4GB in size. Performance wise this isn’t too bad on my system, however setting BIOS to allocate 8GB will allow for ~8GB models to use the (A)GPU only..(and then also smaller models naturally).. which is faster, but wastes memory in most scenarios. I also noticed some instabilities with 8GB VRAM allocated, but I did not care to investigate it further.

I haven’t tried larger models with command line ollama.. i did try 14GB models using LM Studio. It worked, but it crashed my gnome session after a while and besides, I don’t think I like the LM Studios terms so I removed it from my system.

If you have followed along this far you’ve realized that “that guy is full of s**t.. this doesn’t work!” and you’d be right. I have not come to the most important part yet.

If you do -

$ journalctl -fu ollama --no-pager

you will see loglines indicating that ollama does not know about your (A)GPU.. even though ollama clearly stated that it was present when you installed ollama. So we need to remedy that.

I guess there are multiple ways to perform this next step, but I chose the path of least resistance.

$ sudo vim /etc/systemd/system/ollama.service
# insert the following in to the [Service] section. Yes, there is already
# a variable named Environment, we will add one more.
Environment="HSA_OVERRIDE_GFX_VERSION=11.0.2"

# save the file and exit
$ sudo systemctl daemon-reload
$ sudo systectl restart ollama.service

Finding the correct HSA_OVERRIDE_GFX_VERSION" was pain in the proverbial butt! The only place I’ve found it specified is here https://discuss.linuxcontainers.org/t/rocm-and-pytorch-on-amd-apu-or-gpu-ai/19743

I’ll admit that my google foo is not as strong as it once was, but I blame google and not my self (I had to give up on duckduck.. )

for GCN 5th gen based GPUs and APUs HSA_OVERRIDE_GFX_VERSION=9.0.0
for RDNA 1 based GPUs and APUs HSA_OVERRIDE_GFX_VERSION=10.1.0
for RDNA 2 based GPUs and APUs HSA_OVERRIDE_GFX_VERSION=10.3.0
for RDNA 3 based GPUs and APUs HSA_OVERRIDE_GFX_VERSION=11.0.0

I mucked about with 10.3.0, which was the only reference I found to GFX_VERSION, for several hours until I stumbled upon this guy: qkiel So, thank you qkiel, you saved my sanity.

So, there’s that.

I leave you with this
