When I rewrote the interrupt management code in Windows, I wrote it such
that you could, through a set of WMI objects, affect which IRQs a set of PCI
devices was attached to. (The motherboard forces certain devices to share
an IRQ steering device, but beyond that, the OS has control.)
I also set it up so that you could influence the priority choice.
When Microsoft (famously) threw out the Longhorn code and started over on
Windows Vista, I had already moved on to working on virtual machines. This
code was removed in the name of simplification and testability.
Sorry. I tried.
