I think we should not trigger it manually. What's the purpose? If you use setpci to do SecondaryBusReset directly, all the devices behind the bridge are reset suddenly while xend/Dom0/Xen don't know that... We don't check if "the host BARs are enabled" or not. -- Dexuan -----Original Message----- From: Neo Jia [mailto:neojia@xxxxxxxxx] Sent: 2008年8月29日 13:16 To: Cui, Dexuan Cc: xen-devel@xxxxxxxxxxxxxxxxxxx; Han, Weidong Subject: Re: [Xen-devel] Secondary bus reset for VT-d device Can I trigger it manually? What happens if I just use setpci to do a "secondary bus reset"? Will Xen be able to check if the host BARs are enabled for the device before putting it into the guest?
