GPUs on a Raspberry Pi Compute Module 4!

tl;dw - I couldn't get the video cards to work. But I got very close!

And I learned a lot in the process. I'm putting everything here: https://pipci.jeffgeerling.com

After I learned the Raspberry Pi Compute Module 4 IO Board comes with a PCIe slot, I know the first thing I thought about testing was a graphics card. The Mali GPU inside the Pi 4 is decent on its own, but what if you could use external video cards, for mining, for rendering, or for CUDA or other GPU-accelerated computing purposes?

So that's what I sought to try out in this video, going boldly where... a couple others have gone before, but unsuccessfully!
