int arch_setup_msi_irq	(	struct pci_dev *	dev,
		struct msi_desc *	desc
	)

Called when a driver request MSI interrupts instead of the legacy INT A-D. This routine will allocate multiple interrupts for MSI devices that support them. A device can override this by programming the MSI control bits [6:4] before calling pci_enable_msi().

: Device requesting MSI interrupts : MSI descriptor

Returns 0 on success.

void arch_teardown_msi_irq

(

unsigned int

irq

)

Called when a device no longer needs its MSI interrupts. All MSI interrupts for the device are freed.

: The devices first irq number. There may be multple in sequence.
