These flags are to inform the pci-bios-v2 server to either use MSI or MSI-X interrupts rather than the default irqs. If a device can use both MSI and MSI-X interrupts and the MSI flag is specified, then only MSI interrupts will be allocated.

Hugh,

the flags PCI_USE_MSI and PCI_USE_MSIX are not documented.

What are their semantic?  Does it work with the current version of pci-bois-v2 ?

Best Regards

device you are concerned about.
