Hi Bjorn, hi Alex, below are two patches I'd love to see in 4.8 to improve the pci_alloc_irq_vectors interface. I've realized we need these while starting a mass conversion of the MSI-X users to the new interface, and getting it into 4.8 before users show up should make life a lot easier. The positive flags things comes out of the fact that a lot of driver want MSI-X only without any fallback, or some elaborate differences for the different interrupt schemes. For example while most modern devices use one MSI-X vector per queue and scale nicely from the MSI to the MSI-X scheme many older devices use a MSI-X vector per functionality in the ISR, so they might wan to allocate them differently. The second one ensures the legacy interrupt line is actually enabled before using it, because some devices like MSI-X might actually have it disable by default. -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
