Wow, that sounds like a very impressive level of separation of concerns. May I kindly ask for some links for further reading? If you have any handy.

It's a pretty standard driver model internal abstraction layer.

In kernel space you as the hardware manufacturer implement a display miniport driver, and heavily lean on dxgkrnl.sys

And implement interfaces like this one for D3D12 https://learn.microsoft.com/en-us/windows-hardware/drivers/d...

There's quite a bit though and it's kind of spread across several sections on MSDN.

FWIW, this is also how Metal and OpenGL work on macOS. It's hard work, for sure, but it's also a pretty common pattern.
