CONFIG_TICKLESS_CAPABLE

(No prompt – not directly user assignable.)

Type: bool

Help

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