Selects the token pop mode for an DLB port.

Definition at line 27 of file rte_pmd_dlb.h.

Function Documentation

__rte_experimental int rte_pmd_dlb_set_token_pop_mode	(	uint8_t	dev_id,
		uint8_t	port_id,
		enum dlb_token_pop_mode	mode
	)

Warning

EXPERIMENTAL: this API may change, or be removed, without prior notice

Configure the token pop mode for an DLB port. By default, all ports use AUTO_POP. This function must be called before calling rte_event_port_setup() for the port, but after calling rte_event_dev_configure().

Note

The defer_sched vdev arg, which configures all load-balanced ports with dequeue_depth == 1 for DEFERRED_POP mode, takes precedence over this function.

Parameters

dev_id	The identifier of the event device.
port_id	The identifier of the event port.
mode	The token pop mode.

Returns

• 0: Success
• EINVAL: Invalid dev_id, port_id, or mode
• EINVAL: The DLB is not configured, is already running, or the port is already setup
