Communication from user mode app to WDDM Miniport

NTDEV
1

This is for Windows 7…

I would like to retrieve a handful of DWORDs from my WDDM Display Miniport from a user mode application for a special operation…

If not is it possible to just have the user mode app send a custom command or message to the miniport?

Have you tried DX escape commands? Those get routed to the miniport

Do you mean a DirectX Escape? I’m having trouble finding the right thing using Google.
