Hello, I recently added a PCI-e serial card to my known working x86-64 Jailhouse box. It got bdf 02:00.0 on the bus and Linux without Jailhouse works fine.
However the port ceased to work when I enable Jailhouse. It seems like that during IOMMU remapping, pci_enabled_msi_vectors reported 0 for the card. The card should have at least one MSI interrupt vector. I observed that the Linux driver only register and enable the device IRQ when it's in used by some application, but I am not sure this is the cause. Any suggestions or guideline to add a PCI-e serial card to a x86-64 machine? ----- Yang -- You received this message because you are subscribed to the Google Groups "Jailhouse" group.
