int pci_enable_msi_range(struct pci_dev * dev, int minvec, int maxvec);

ARGUMENTS

dev

device to configure

minvec

DESCRIPTION

This function tries to allocate a maximum possible number of interrupts in a range between minvec and maxvec. It returns a negative errno if an error occurs. If it succeeds, it returns the actual number of interrupts allocated and updates the dev's irq member to the lowest new interrupt number; the other interrupt numbers allocated to this device are consecutive.
