Also, you might encode bus,slot,function according to the PCI spec. So that gives: long usr_pci_open(unsigned pcidomain, unsigned devspec, __u64 dmamask); (with the user library returning an int instead of long) - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
