At least on my device (PCI ID 1131:7162) there is no MSI-X capability, so that's not an option for you. The current Linux implementation does not support more than one MSI interrupt, so you just get one interrupt with pci_enable_msi(). I think it's probably simplest for you to forget about MSI until you have the basic driver working. > Ok.
