I am trying PCI passthrogh of Mellanox Infinihost III Lx chip based Infiniband and TG3 ethernet PCIe cards on Centos 5.2 Full virtualized guest with Xen 3.3.0
ib_mthca driver fails with QUERY_FW failed probe failed with errror -11 But interestingly tg3 driver says "Could not get MSI interrupts falling back to INTx" and works fine So, 1) why Xen could not get the MSI interrupts working ? 2) Should we have INT-x falling back method for Mellanox driver also if its needed ? ~subbu
