void pci_disable_device

(

struct pci_dev *

)

pci_disable_device - Disable PCI device after use

Signal to the system that the PCI device is not in use by the system anymore. This only involves disabling PCI bus-mastering, if active.

Parameters:

dev

PCI device to be disabled

Definition at line 122 of file linux26/lib/src/arch/l4/pci.c.

int pci_enable_device

(

struct pci_dev *

dev

)

pci_enable_device - Initialize device before it's used by a driver.

Initialize device before it's used by a driver. Ask low-level code to enable I/O and memory. Wake up the device if it was suspended. Beware, this function can fail.

Parameters:

dev

PCI device to be initialized
