[FEAT] Acceleration support for non-Nvidia GPUs

[Den4enko]

Is this a new feature request?

• I have searched the existing issues

Wanted change

I would like the option to use my integrated AMD iGPU to accelerate graphical apps.
After re-basing Webtop to Selkies, enabling GPU acceleration using /dev/dri mapping has no effect. Now it uses lvmpipe as the "GPU"

Reason for change

Improve the overall graphical performance of non-Nvidia GPUs

Proposed code change

This is next on my todo, working on forking X now.

Should have DRI3 in by Monday.

dri3.mp4

It all works and I have it working across all distros (this is Alpine)
The work left is making this a patch and building out the X build logic for all the baseimages.

@Den4enko

Can you please test this out?

docker run --rm -it --device /dev/dri:/dev/dri --shm-size=1gb -p 3001:3001 lsiobase/selkies:alpine322 bash

sudo apk add mesa-demos
glxheads

Alpine is the first to get DRI3, I am building out all the infra for the rest now, will have updates tomorrow.

Also if you have multiple GPUs we need testing there, I could not break it but every setup is different you can use like -e DRINODE=/dev/dri/renderD129 to change it.

That works!
