15 // Overview: |
|
16 // Test power down and wakeup event notification |
|
17 // API Information: |
|
18 // Power::PowerDown(), Power::RequestWakeupEventNotification() |
|
19 // Details: |
|
20 // - Arm a wakeup timer, enable wakeup events, enter standby mode, get woken up. |
|
21 // - Test RequestWakeupEventNotification(): arm a timer, request notification, |
|
22 // wait for timer to expire, verify event has been notified, issue another |
|
23 // notification request, disable wakeup events, arm another timer, verify |
|
24 // wakeup event has not been notified, cancel the notification request and |
|
25 // close the timer. |
|
26 // - Verify that a slave process panics because it hasn't and capability. |
|
27 // - Confirm the number of open handles and pending requests are as expected. |
