Add Steam Deck OLED GPU

[Telaneo]

The original Steam Deck's GPU has already been added, listed as '0x1002:0x163f:1:3:Van Gogh', but the OLED version, codename Sephiroth, hasn't.

Here's the output from lspci -nn on my own Steam Deck OLED:

If you need me to run anything else on the Steam Deck OLED to be able to add its GPU to gpus.txt, then please say so.

I doubt I will enable Steamdeck GPUs, since FAH can easily damage them as they are not created for super high compute workloads. Please use your very expensive handheld gaming devices for what they were created

today's expensive handhelds are tomorrows modded, headless folding clusters..

I really really really doubt that

Anyone with a Steam Deck GPU who wants to test it can run some sample OpenMM workloads and monitor GPU utilization, temperature etc over an extended period. That is the software library that FAH uses for GPU folding and is representative of the kind of loads FAH will put the system under. As mentioned, it could potentially damage the hardware or shorten its life.

If it runs well and doesn't overheat, then it's possible that it could be added to the GPU list (that's just a guess and I don't want to put words in anyone's mouth), but you'd have to do the testing yourself. There's no way that muziqaz is going to add it to the list if there's a chance that it will damage people's devices and potentially corrupt scientific research, and it's not powerful enough to motivate FAH devs to test it themselves. It would be up to the device owner to test it. I can walk anyone through setting up an OpenMM simulation of the type that FAH uses that will push the GPU to its limits, if that would be helpful.

N.B. I wonder how useful it would be if the client could use the GPU whitelist to reduce the utilization of certain GPUs, basically whitelisting things like the Steam Deck GPU, but capping it to 75%. I suspect the number of extra folders this would bring in would be too few to warrant the developer manpower.

All Deck GPUs are on the list, but with Species 0 designator, which means they are disabled. Technically I wouldn't want to be a nanny state, but those mobile handhelds are too awesome piece of kit to try a d destroy them with folding
