Hi,
I am now adding features to the VT-d emulation for q35 chipset. I
think it is good to know what features q35 chipset supports exactly.
However I can't find materials about this. Does anyone know this? Or
it will be fine if someone can tell me the value of the Capability
Register and Extended Capability Register of the VT-d on q35.
Any help is appreciated!
Thanks very much!
Regards,
Le

The kernel reports those registers during boot-up, so we would just need
"dmesg | grep dmar" from a real 82Q35 box (Intel 3 Series).

Thanks! But my computer seems not to be Intel 3 Series. It seems to be
"7 Series/C210 Series Chipset Family". What's more, Acer seems to
disable and hide the VT-d support of it.
