looking at i/o space

WINDBG
1

Hello,

How can I look at I/O space using Windbg?
There is an option inside the properties of the memory window about I/O but
I do not understand how it is used.

Thanks

Hi,

You can easily do manually with ib/iw/id and ob/ow/od. Never tried from the
memory window…

The memory window offers all of the various options for looking at
different I/O spaces. If your driver is using I/O space and you want to
see what it’s touching you would use matching parameters.

If you want to do a simple I/O space lookup you would use an interface
type of Isa, bus number 0, address space 1. The I/O address is the
offset.
