typedef int(* rte_bus_cmp_t) (const struct rte_bus *bus, const void *data)¶

Bus comparison function.

Parameters

Returns

Definition at line 80 of file rte_bus.h.

const char* rte_bus_name (const struct rte_bus * bus)¶

Retrieve a bus name.

Parameters

Returns

int rte_bus_scan (void)¶

Scan all the buses.

Returns

int rte_bus_probe (void)¶

For each device on the buses, perform a driver 'match' and call the driver-specific probe for device initialization.

Returns

void rte_bus_dump (FILE * f)¶

Dump information of all the buses registered with EAL.

Parameters

struct rte_bus* rte_bus_find (const struct rte_bus * start, rte_bus_cmp_t cmp, const void * data)¶

Bus iterator to find a particular bus.

This function compares each registered bus to find one that matches the data passed as parameter.

If the comparison function returns zero this function will stop iterating over any more buses. To continue a search the bus of a previous search can be passed via the start parameter.

Parameters

Returns

struct rte_bus* rte_bus_find_by_device (const struct rte_device * dev)¶

Find the registered bus for a particular device.

struct rte_bus* rte_bus_find_by_name (const char * busname)¶

Find the registered bus for a given name.

enum rte_iova_mode rte_bus_get_iommu_class (void)¶

Get the common iommu class of devices bound on to buses available in the system. RTE_IOVA_DC means that no preference has been expressed.

Returns
