Hi All, 

I have a windows 7 as my domU and some windows based drivers are not fully functional (like: touchpad-driver etc ) because they are SMBus based. I was looking at a way to passthrough the SMBus at 00:1f.03 on south bridge ( 00:1f.0), I was debugging at pt-graphics.c and understand that it is detecting the south bridge and passing it through but the other functions for the same dev-id are not getting passed through. Seeking help if someone can help me to get the function '3' also pass through.

I am using Xen-4.2.0 and dom-0 linux kernel is 3.9.4. My dom-0 is Fedora-17-64bit based.

thanks 
tsk

Do you mean that you are looking to pass through the host SMBus to a guest, or that you are looking for qemu to emulate an SMBus?
