Detailed Description

EM internal event types & definitions

Definition in file em_event_types.h.

Macro Definition Documentation

◆ USER_FLAG_SET

#define USER_FLAG_SET 1

Used to detect whether the event's event-header has been initialized by EM.

Set the odp-pkt/vector user-flag to be able to recognize events that EM has created vs. events from pkt-input that needs their ev-hdrs to be initialized before further EM processing.

Definition at line 56 of file em_event_types.h.

Typedef Documentation

◆ ev_hdr_state_t

typedef struct ODP_PACKED ev_hdr_state_t

Event state information, updated on valid state transitions. "Best effort" update, i.e. atomic update of state is not guaranteed in invalid simultaneous state updates.

Contains the previously known good state and will be printed when detecting an invalid state transition.

◆ event_hdr_t

typedef struct event_hdr event_hdr_t

Event header

SW & I/O originated events.

◆ event_prealloc_hdr_t

typedef union event_prealloc_hdr event_prealloc_hdr_t

Event header used only when pre-allocating the pool during pool creation to be able to link all the event headers together into a linked list. Make sure not to overwrite the event state information in the header with the linked list information.

Function Documentation

◆ ODP_ALIGNED()

union ODP_ALIGNED ( sizeof(uint64_t) )

Event-state counters: 'evgen', 'ref_cnt' and 'send_cnt'.

Atomically updated as one single var via 'evstate_cnt_t::u64'.
