| |
To avoid spurious timer interrupts when KTIME_MAX is used, we need to configure set_state_oneshot_stopped(). Although implementing this is optional, it still affects things like power management for the extra timer interrupt.
Check commit 8fff52fd5093 ("clockevents: Introduce CLOCK_EVT_STATE_ONESHOT_STOPPED state") for more information.
