Detailed Description
DLB PMD-specific functions.
Definition in file rte_pmd_dlb2.h.
Macro Definition Documentation
#define RTE_PMD_DLB2_GET_QID_DEPTH(x) ((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) ((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) (((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) ((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.

Enumeration Type Documentation
enum rte_pmd_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 rte_pmd_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 RTE_PMD_DLB2_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 parameter dev_id, port_id, or mode
- •
-
EINVAL: The DLB2 device is not configured or is already running, or the port is already setup
