| # Advanced Usage |
| |
| Now we'll cover a couple of advanced use cases of power framework. These are |
| particularly geared towards optimizing for performance. It may be useful to read |
| [Power framework in depth][in_depth] before looking at these advanced use |
| cases. |
| |
| Both of the advanced usages focus on reducing the number of power framework |
| interactions and are good (possibly the only) options for high event rate |
| systems. Most of the time when the system is awake it is because there is a |
| high-level policy keeping it that way, for example, only sleep if we've gone 5 |
| minutes without a keyboard or mouse event. This means that _most_ of the time |
| the system will stay awake long enough for us to get our work done and it is |
| only when the system is waking from sleep or trying to suspend that we need to |
| interact with power framework. In other words, it is only at system state |
| transition edges into and out of suspension where power framework interaction is |
| required. At these edges our code must do additional work. |
