CONFIG_SYSTEM_CLOCK_SLOPPY_IDLE

Timer allowed to skew uptime clock during idle

Type: bool

Help

When true, the timer driver is not required to maintain a
correct system uptime count when the system enters idle.
Some platforms may take advantage of this to reduce the
overhead from regular interrupts required to handle counter
wraparound conditions.

Defaults

No defaults. Implicitly defaults to n.
