RTE devargs: list of devices and their user arguments
This file stores a list of devices and their arguments given by the user when a DPDK application is started. These devices can be PCI devices or virtual devices. These devices are stored at startup in a list of rte_devargs structures.
Definition in file rte_devargs.h.
enum rte_devtype |
Type of generic device

int rte_eal_parse_devargs_str | ( | const char * | devargs_str, |
char ** | drvname, | ||
char ** | drvargs | ||
) |
Parse a devargs string.
For PCI devices, the format of arguments string is "PCI_ADDR" or "PCI_ADDR,key=val,key2=val2,...". Examples: "08:00.1", "0000:5:00.0", "04:00.0,arg=val".
For virtual devices, the format of arguments string is "DRIVER_NAME*" or "DRIVER_NAME*,key=val,key2=val2,...". Examples: "eth_ring", "eth_ring0", "eth_pmdAnything,arg=0:arg2=1".
The function parses the arguments string to get driver name and driver arguments.
devargs_str | The arguments as given by the user. |
drvname | The pointer to the string to store parsed driver name. |
drvargs | The pointer to the string to store parsed driver arguments. |
int rte_eal_devargs_add | ( | enum rte_devtype | devtype, |
const char * | devargs_str | ||
) |
Add a device to the user device list
For PCI devices, the format of arguments string is "PCI_ADDR" or "PCI_ADDR,key=val,key2=val2,...". Examples: "08:00.1", "0000:5:00.0", "04:00.0,arg=val".
For virtual devices, the format of arguments string is "DRIVER_NAME*" or "DRIVER_NAME*,key=val,key2=val2,...". Examples: "eth_ring", "eth_ring0", "eth_pmdAnything,arg=0:arg2=1". The validity of the driver name is not checked by this function, it is done when probing the drivers.
devtype | The type of the device. |
devargs_str | The arguments as given by the user. |
unsigned int rte_eal_devargs_type_count | ( | enum rte_devtype | devtype | ) |
Count the number of user devices of a specified type
devtype | The type of the devices to counted. |
void rte_eal_devargs_dump | ( | FILE * | f | ) |
This function dumps the list of user device and their arguments.
f | A pointer to a file for output |
struct rte_devargs_list devargs_list |
Global list of user devices
