All,

I'm doing hardware bringup and am suspecting that our adapter is
dma-ing to the wrong physical address.  We know we're getting a PCI
bus transaction when we expect it, but we don't know where it's going.

Until the bus analyzer arrives, what's the easiest way to go through
physical memory looking for a known pattern?  Is it really as simple as
opening /dev/mem and marching through it?

Thanks,
-JohnG
