const char* octeon_get_pci_interrupts

(

void

)

Return the mapping of PCI device number to IRQ line. Each character in the return string represents the interrupt line for the device at that position. Device 1 maps to the first character, etc. The characters A-D are used for PCI interrupts.

Returns PCI interrupt mapping

int __init octeon_pci_pcibios_map_irq	(	const struct pci_dev *	dev,
		u8	slot,
		u8	pin
	)

Map a PCI device to the appropriate interrupt line

: The Linux PCI device structure for the device to map : The slot number for this device on BUS 0. Linux enumerates through all the bridges and figures out the slot on Bus 0 where this device eventually hooks to. : The PCI interrupt pin read from the device, then swizzled as it goes through each bridge. Returns Interrupt number for the device
