STATUS_TIMER_RESUME_IGNORED
The waitable timer resume request was not honored
Waitable timers can request resume behavior through the timer API. STATUS_TIMER_RESUME_IGNORED indicates that the resumable aspect of the request was ignored; the timer operation should not be interpreted as guaranteeing that a sleeping system will wake for the deadline.
Keep the absolute or relative due time separate from the wake requirement. A timer can still be meaningful for normal scheduling even when resume support is unavailable or not honored by the platform. For diagnostics, record the timer API, resume flag, power state and whether the component requires wake-from-sleep semantics. Do not compensate by repeatedly rearming a short-period timer.
What to inspect
- Record the requested due time, periodic interval, and resume flag.
- Check whether wake-from-sleep is a hard requirement or only an optimization.
- Verify platform power and timer capabilities before depending on the timer as a wake source.
