This is quite amazing!
If Xsgi is using the onboard framebuffer, how does it “switch” the attached display to the voodoo, or is it using the voodoo to do the rendering then pushing the data through the onboard framebuffer (CRIME)?
The Voodoo1 & Voodoo2 cards are just 3D accelerators, they have VGA passthrough functionality. On-board video goes to the input of the V1/V2, display connects to the output. When it’s doing 3D stuff, it switches to the V1/V2 output. X server is not involved at all, nor is there data pushed through CRIME. In fact, you can connect one display to CRIME and one to the Voodoo card, and you will see both outputs.
Ohh, I see, it was hard to tell by looking at the stripped O2, that’s a really neat project, thanks for sharing, hoping to see more of that in the future!
Is that an O2 board out of the case on the desk in front of the monitor?
Yep 🙂
