CONFIG_TICKLESS_CAPABLE

Timer driver supports tickless operation

Type: bool

Help

Timer drivers should select this flag if they are capable of supporting tickless operation. That is, a call to z_clock_set_timeout() with a number of ticks greater than one should be expected not to produce a call to z_clock_announce() (really, not to produce an interrupt at all) until the specified expiration.

Defaults

No defaults. Implicitly defaults to n.
