Detailed Description

Idle hooks given by the user via this struct to the em_init() will be called by the EM dispatcher on each core.

The EM dispatcher will call:

• to_idle_hook when a core doesn't get any more events from scheduled or local queues after the core has been active
• to_active_hook when a core gets events after being idle
• while_idle_hook when a core continues being idle

Not all the idle hooks need to be provided, use NULL for unused idle hooks.

Note

Notice that doing heavy processing in the hooks might significantly impact performance.

Only used if EM_IDLE_HOOKS_ENABLE != 0
