List GPU memory and usage

[vadi2]

Hey! I love TopHat for its powerful but simple design. Would you consider adding GPU memory and usage as stats? It wasn't really necessary before with gaming (the game covered the full screen anyway), but all of the AI-based workloads are putting a fair bit of stress on the GPU now - and it would be nice to see what's going on with your hardware at a glance, just like with cpu/ram/disk.

There is currently no unified API to get these measurements. Ideally they would come from libgtop, and although there was an attempt to add GPU usage to libgtop it was not merged.

My computer has an AMD graphics card and it's rather easy to get measurements from the amdgpu driver through sysfs. I don't have access to a computer with an nvidia graphics card (and even so there are at least two different drivers, no?) so I can't work on that.

You may take a look at this repo for Nvidia implementation: https://github.com/UshakovVasilii/gnome-shell-extension-freon/blob/55bcd7c48181c8c18a9210828b8723ac3fe1d4c7/freon%40UshakovVasilii_Github.yahoo.com/nvidiaUtil.js#L142

Although there are no standard tooling I think you can probably call libgtop for the gpu vendor info. Or just check for availability of GPU specific CLI tools. Next call the corresponding tools for info.

Also I got an NVIDIA driver here's all the GPU info options you can poll:

Hope it helps.

glxinfo from mesa-utils appears to provide the GPU memory at least.

I don't have an AMD GPU to test this out. @tumist could you confirm if the tool works in AMD too? Also if someone got intel graphics to compare too, would be helpful.

If it works I can open a PR regarding this.

It works with an AMD GPU too, here is what I got:
