Detailed Description

DLB PMD-specific functions.

Definition in file rte_pmd_dlb2.h.

Macro Definition Documentation

#define RTE_PMD_DLB2_GET_QID_DEPTH( x)

Value:

((x)->rsvd & 0x3)

Macro function to get QID depth of rte_event metadata. Currently lower 2 bits of 'rsvd' field are used to store QID depth.

Definition at line 26 of file rte_pmd_dlb2.h.

#define RTE_PMD_DLB2_SET_QID_DEPTH( x,  v)

Value:

((x)->rsvd = ((x)->rsvd & ~0x3) | (v & 0x3))

Macro function to set QID depth of rte_event metadata. Currently lower 2 bits of 'rsvd' field are used to store QID depth.

Definition at line 32 of file rte_pmd_dlb2.h.

#define RTE_PMD_DLB2_GET_QE_WEIGHT( x)

Value:

(((x)->rsvd >> 2) & 0x3)

Macro function to get QE weight from rte_event metadata. Currently upper 2 bits of 'rsvd' field are used to store QE weight.

Definition at line 38 of file rte_pmd_dlb2.h.

#define RTE_PMD_DLB2_SET_QE_WEIGHT( x,  v)

Value:

((x)->rsvd = ((x)->rsvd & 0x3) | ((v & 0x3) << 2))

Macro function to set QE weight from rte_event metadata. Currently upper 2 bits of 'rsvd' field are used to store QE weight.

Definition at line 44 of file rte_pmd_dlb2.h.

Enumeration Type Documentation

enum dlb2_token_pop_mode

Warning

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

Selects the token pop mode for a DLB2 port.

Definition at line 52 of file rte_pmd_dlb2.h.

Function Documentation

__rte_experimental int rte_pmd_dlb2_set_token_pop_mode (uint8_t dev_id, uint8_t port_id, enum dlb2_token_pop_mode mode)

Warning

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

Configure the token pop mode for a DLB2 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().

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 DLB2 is not configured, is already running, or the port is already setup
