SYNOPSIS

9       int pci_enable_msi_range(struct pci_dev * dev, int minvec, int maxvec);
10

ARGUMENTS

12       dev
13           device to configure
14
15       minvec
16           minimal number of interrupts to configure
17
18       maxvec
19           maximum number of interrupts to configure
20

DESCRIPTION

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