Tracking adresses of write and read

[Fabrice Gautier <gautier@email.enst.fr>]

Hi,

I'm writing a driver for some special hardware. It's a PCI device.
First I have a kernel module which ioremap the hardware registers. Then
I have a user space program which mmap the device to user space. And
then i read/write the devices registers throught this mmap-ed region.

I would like to be abble to see which physical adress i'm
writing/reading to when I write/read in the mmap-ed memory.

Who could i do this? 

Thanks.
