Hi all,
I am into writing Linux device drivers. I have a query regarding usage
of inb, outb instruction in the drivers.
What is the address we need to pass to inb, oub instructions? I mean, Is
it a Physical address or a Virtual address?
Regards,
Mukund jampala

No,
It is I/O port address. It is different from Memory address. In x86,
I/O Port addresses are 16bit.
