!dd command

If someone looks at a pci cards resourlces from the device manager and sees
a memory resource on a card whose address is, for example, 0xdf004000.
SHould they be able to display it’s contents with the !dd command? WHen
they try it they get an error saying that the dump of the address
failed…

dd dumps a virtual memory address.

PCI memory mapped IO lives in physical address space.

Cheers,
