[Xen-devel] Will Xen change the mapping after PCIe reset for the VT-d device?

["Neo Jia" <neojia@xxxxxxxxx>]

hi,

After a secondary bus reset Xen will restore the PCI configure space
for the VT-d device, will the mapping still valid as we are using the
original BARs?

Let's assume the guest device driver will not change the BARs as Xen
only save the register after guest shutdown/reset.

Thanks,
Neo

probably today we haven't the technology we are using!
