DLB PMD-specific functions.

Definition in file rte_pmd_dlb2.h.

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.








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.








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.








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.

Warning

Selects the token pop mode for a DLB2 port.


Definition at line 52 of file rte_pmd_dlb2.h.












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
    • 











Warning


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


Configure various port parameters. This function must be called
    before calling rte_event_port_setup() for the port, and after calling
    rte_event_dev_configure().




Parameters


dev_id The identifier of the event device.


port_id The identifier of the event port.


flags Bitmask of the parameters being set.


val Structure containing the values of parameters being set.


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
    •
