Function Documentation

int ddekit_pci_disable_device

(

struct ddekit_pci_dev *

dev

)

Disable PCI device.

Definition at line 247 of file ddekit/src/pci.c.

int ddekit_pci_enable_device

(

struct ddekit_pci_dev *

dev

)

Enable PCI device.

Definition at line 242 of file ddekit/src/pci.c.

struct ddekit_pci_dev* ddekit_pci_find_device	(	int *	bus,
		int *	slot,
		int *	func,
		struct ddekit_pci_dev *	start
	)			[read]

Find a PCI device.

Parameters:

	bus	pointer to bus number or DDEKIT_PCI_ANY_ID
	slot	pointer to slot number (devfn >> DEVFN_SLOTSHIFT) or DDEKIT_PCI_ANY_ID
	func	pointer to func number (devfc & DEVFN_FUNCMASK) or DDEKIT_PCI_ANY_ID
	start	search device list only behind this device (excluding it!), NULL searches whole device list

Return values:

	bus	bus number
	slot	slot number
	func	function number

Returns:

device a valid PCI device

NULL if no device found

static ddekit_pci_dev_t* ddekit_pci_find_device_fixed	(	int	bus,
		int	slot,
		int	func
	)			[inline, static]

Find PCI device for a given (bus, slot, func) tuple.

This function is only used internally by the pci_{read,write}{b,l,w} functions. It was once called pci_find_device, but this caused confusion with the "real" find_device() functionality provided by L4IO and the Linux PCI subsystem.
