[REQUEST] Show multiple GPUs

[adrianlyjak]

This was discussed fairly thoroughly in #426, the issue to add GPU support, but that's been fixed, so figured I'd open a new issue to keep this particular feature visible.

I have multiple GPUs, and expect that a lot of people using btop are futzing around on servers doing ML and want to monitor GPU usage. btop currently supports GPUs (yay!), however it just shows 1

My personal preference would be to use the CPU style of UI, but modified a little to support GPUs

• treat each GPU like the CPU UI treats a core. It would show current GPU usage, current Memory usage, and current power usage.
• the historical graph would show average total GPU utilization over time like CPU does

While this leaves some historical information out, this approach seems like it should be simple and fit within the current btop design.

There were some other alternatives discussed in #426, such as binding digits 5-0 to display different gpus. This seems perhaps like it might make the feature more complicated to implement well. I personally don't have strong opinion though, and just want to see my other GPU

i can see 2 GPUs on the left side of the app (with the graph), but on the right side it shows only GPU0 and a blank line following it

here's a comparison, of 1gpu vs 2gpu setup:

not sure if that's a separate issue or the same as on topic

Try pressing 5, 6 to toggle GPU settings.

if i press 5 it shows separately info for gpu 0 and if 6 - for gpu 1

but then this detailed info is hidden - in the overview it shows only gpu 0 and a blank line
