So to summary, I think we only need following change to fix the regression: int pcibios_alloc_irq(struct pci_dev *dev) {

Yes, that works too and has the added benefit that no driver can attach to the iommu device and get in the way of the driver.
Will you send the patch for this change or should I do it?
Hi Joerg, We are on leave for Chinese National Holiday and has limited access to my working environment. It would be appreciated if you could help to send out a patch for it. Otherwise I will send out a patch within 2-3 days. Thanks! Gerry
