* APerformanceHint allows apps to create performance hint sessions for groups
* of threads, and provide hints to the system about the workload of those threads,
- * to help the system more accurately allocate resources for them. It is the NDK
+ * to help the system more accurately allocate power for them. It is the NDK
* counterpart to the Java PerformanceHintManager SDK API.
*
- * This API is intended for periodic workloads, such as frame production. Clients are
- * expected to create an instance of APerformanceHintManager, create a session with
- * that, and then set a target duration for the session. Then, they can report the actual
- * work duration at the end of each cycle to inform the framework about how long those
- * workloads are taking. The framework will then compare the actual durations to the target
- * duration and attempt to help the client reach a steady state under the target.
- *
- * Unlike reportActualWorkDuration, the "notify..." hints are intended to be sent in
- * advance of large changes in the workload, to prevent them from going over the target
- * when there is a sudden, unforseen change. Their effects are intended to last for only
- * one cycle, after which reportActualWorkDuration will have a chance to catch up.
- * These hints should be used judiciously, only in cases where the workload is changing
- * substantially. To enforce that, they are tracked using a per-app rate limiter to avoid
- * excessive hinting and encourage clients to be mindful about when to send them.
