int pci_enable_msi_range ( | struct pci_dev * dev, |
int minvec, | |
int maxvec) ; |
dev
device to configure
minvec

maxvec
maximum number of interrupts to configure
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

the other interrupt numbers allocated to this device are consecutive.
