Hi,

I am relatively new to linux user space programming. I have a PCI
device which has memory mapped register sets. The driver works fine on
an intel Pentium M. I can access the registers in the driver through
PCI BAR0. Now I am writing a user space diagnostic program for the PCI
device, I can access the PCI BAR0 value, how can I convert it into user
space virtual address so that I can read the registers from the user
space?

Your advice and help is greatly appreciated !!

thanks

Mark
