FW16 dGPU causes segfaults/very poor Performance on Linux

Framework Laptop 16 Linux
1

Hi,

Unfortunately I cannot run games on my dGPU. Whenever I force a game to run via the dGPU via DRI_PRIME=1 the laptop nearly freezes. Like I get a new Frame every ten seconds. The OS is completely unusable in this state, requiring me to kill the process from another TTY. When I force games like Xonotic or OpenArena to run on the dGPU they segfault. Internal GPU is fine for steam and non-steam games. Forcing glxgears/vkcube to run on the dGPU does not cause problems.

Is this a hardware issue or more likely a software issue? I’m running Fedora 40 KDE on the Framework 16.

My only experience is on Ubuntu, but I had to install the closed source drivers before I could really use the dGPU.

Are you using the internal screen or an external attached? Something to try would be plugging a monitor into the USBC/Displayport port directly on the dGPU and see if that makes a difference. Maybe the issue has something to do with backfeeding the video through the iGPU to get to the onboard display.

Same thing. Playing Doom 2016 it immediately drops to 1 FPS when the menu screen loads.

4

Running the Unigine Superposition Benchmark it works just fine. Using the dGPU. Weird. This benchmark has been the only thing I could get to run on the dGPU.

On a live USB Ubuntu 24.04 system I am able to run openarena on the dGPU just fine.

Sounds more and more like a software issue

This is a relevant snippet from dmesg:

I can provide more in depth information. But I am not sure what would be important/helpful.

I found this stack overflow that describes a similar message to yours - firmware - amdgpu SMU driver if version mismatch overrides power limit - Unix & Linux Stack Exchange

The question never got a response, but OP updated saying that it turns out the message in question happens when the dGPU goes into a low power mode and offloads compute responsibility to the iGPU. Are you running the game with DRI_PRIME=1 in the launch options? You could also try explicitly turning on the dGPU in bios to see if it’s related to the hybrid graphics switchover.

Yes I am making use of DRI_PRIME=1. I don’t see an option to disable the iGPU in the BIOS.

Another thing I noticed:

  • glmark2 - works
  • DRI_PRIME=1 glmark2 - works
  • glmark2-wayland - works
  • DRI_PRIME=1 glmark2-wayland - segfaults
8

Ok so the 1FPS issue in steam games is because DRI_PRIME=1 switches to software rendering via llvmpipe. Using DRI_PRIME=1 DXVK_FILTER_DEVICE_NAME="AMD Radeon RX 7700S (RADV NAVI33)" does work as intended. The segfaults seem to be related to SDL titles on wayland.

im pretty sure if you are using vulkan you need to use DRI_PRIME=1! to forcibly apply it anyway. for dxvk, i believe that DXVK_FILTER_DEVICE_NAME="[your gpu]" on its own should be enough (and your DRI_PRIME=1 is doing nothing). If you omit the ! from DRI_PRIME it only affects opengl titles, which cannot choose the gpu themselves.

its also possible to use vendor id and device id with DRI_PRIME (see mesa documentation on environment variables). so DRI_PRIME=1002:7480! should reliably force usage of your dGPU regardless of what order the devices appear in (which can be determined by running vulkaninfo --summary and looking under the “Devices” section)

(this vendor id and product id are those that my laptop reported as belonging to the dgpu using lspci -nn | grep VGA).

This does work very reliable, thanks. Doom 2016 refused to run on the dGPU with all other DRI_PRIME variablles. However openarena, xonotic and various benchmarks still seem to cause segfaults :thinking:

So consider the poor performance part of the problem solved.
