DPDK RTE LCore Keepalive Monitor.

Definition in file rte_keepalive.h.

Number of cores to track.

Note

Must be larger than the highest core id.

Definition at line 24 of file rte_keepalive.h.

typedef void(* rte_keepalive_failure_callback_t) (void *data, const int id_core)

Keepalive failure callback.

Receives a data pointer passed to rte_keepalive_create() and the id of the failed core.

Parameters

data Data pointer passed to rte_keepalive_create()
id_core ID of the core that has failed

Definition at line 45 of file rte_keepalive.h.

typedef void(* rte_keepalive_relay_callback_t) (void *data, const int id_core, enum rte_keepalive_state core_state, uint64_t last_seen)

Keepalive relay callback.

Receives a data pointer passed to rte_keepalive_register_relay_callback(), the id of the core for which state is to be forwarded, and details of the current core state.

Parameters

data Data pointer passed to rte_keepalive_register_relay_callback()
id_core ID of the core for which state is being reported
core_state The current state of the core
last_seen Timestamp of when core was last seen alive

Definition at line 60 of file rte_keepalive.h.

Initialise keepalive sub-system.

Parameters

callback Function called upon detection of a dead core.
data Data pointer to be passed to function callback.

Returns

Keepalive structure success, NULL on failure.

Checks & handles keepalive state of monitored cores.

Parameters

*ptr_timer Triggering timer (unused)
*ptr_data Data pointer (keepalive structure)

Registers a core for keepalive checks.

Parameters

*keepcfg Keepalive structure pointer
id_core ID number of core to register.

Per-core keepalive check.

Parameters

*keepcfg Keepalive structure pointer

This function needs to be called from within the main process loop of the LCore to be checked.

Per-core sleep-time indication.

Parameters

*keepcfg Keepalive structure pointer

If CPU idling is enabled, this function needs to be called from within the main process loop of the LCore going to sleep, in order to avoid the LCore being mis-detected as dead.

Registers a 'live core' callback.

The complement of the 'dead core' callback. This is called when a core is known to be alive, and is intended for cases when an app needs to know 'liveness' beyond just knowing when a core has died.

Parameters

*keepcfg Keepalive structure pointer
callback Function called upon detection of a dead core.
data Data pointer to be passed to function callback.
