RTE Event Ring
This provides a ring implementation for passing rte_event structures from one core to another.
Definition in file rte_event_ring.h.
|
static |
Returns the number of events in the ring
r | pointer to the event ring |
Definition at line 52 of file rte_event_ring.h.
|
static |
Returns the amount of free space in the ring
r | pointer to the event ring |
Definition at line 67 of file rte_event_ring.h.

Enqueue a set of events onto a ring
Note: this API enqueues by copying the events themselves onto the ring, rather than just placing a pointer to each event onto the ring. This means that statically-allocated events can safely be enqueued by this API.
r | pointer to the event ring |
events | pointer to an array of struct rte_event objects |
n | number of events in the array to enqueue |
free_space | if non-null, is updated to indicate the amount of free space in the ring once the enqueue has completed. |
Definition at line 93 of file rte_event_ring.h.
|
static |
Dequeue a set of events from a ring
Note: this API does not work with pointers to events, rather it copies the events themselves to the destination events
buffer.
r | pointer to the event ring |
events | pointer to an array to hold the struct rte_event objects |
n | number of events that can be held in the events array |
available | if non-null, is updated to indicate the number of events remaining in the ring once the dequeue has completed |
Definition at line 129 of file rte_event_ring.h.
struct rte_event_ring * rte_event_ring_lookup | ( | const char * | name | ) |
Search for an event ring based on its name
name | The name of the ring. |
void rte_event_ring_free | ( | struct rte_event_ring * | r | ) |
De-allocate all memory used by the ring.
r | Ring to free |
|
inlinestatic |
Return the size of the event ring.
r | A pointer to the ring structure. |
rte_ring_get_capacity()
. Definition at line 255 of file rte_event_ring.h.
|
inlinestatic |
Return the number of elements which can be stored in the event ring.
r | A pointer to the ring structure. |
