Arbitrary Physical Memory + Control Register Read Write

So I found this driver in my downloads folder, and decided to give it a look in ida. Turns out this driver is very vulnerable as it provides full physical memory r/w, control register modification, pci read write, allocate + deallocate physical memory and more. I only wrote this PoC in 30 minutes and it has important functions like phys r/w, control register + msr r/w, you can take a look at this driver and abuse it to manual map your own driver and more.
