Function Documentation

dao_vfio_init()

int dao_vfio_init

(

void

)

Initialize the VFIO library by opening a container.

Returns

Zero on success.

dao_vfio_device_setup()

int dao_vfio_device_setup	(	const char *	dev_name,
		struct dao_vfio_device *	pdev
	)

Probe a VFIO device and map its regions. Upon a successful probe, the device details are set in the memory referenced by the pdev pointer.

Parameters

dev_name	VFIO device name
pdev	Pointer to VFIO device structure.

Returns

Zero on success.

dao_vfio_device_free()

void dao_vfio_device_free

(

struct dao_vfio_device *

pdev

)

Release a VFIO device and free the associated memory.

Parameters

pdev	Pointer to VFIO device structure.

dao_vfio_fini()

void dao_vfio_fini

(

void

)

Close the container.
