+                   and output devices or between stream and devices.
+                   A <route/> is defined by a set of 3 attributes:

 It is recommended that you move the existing `service` entry with
 `class charger` to the `init.rc` file in your custom health service.
 
+If there are existing actions in the rc file triggered by
+`on property:init.svc.<name>=running`, where `<name>` is the name of your
+existing charger service (usually `vendor.charger`), then the name of the

+ * IExecution represents a reusable execution object with request and most other execution
+ * properties fixed. It is used to launch executions.
+ *
+ * At most one execution may occur on a reusable execution object at any given time, either by
+ * means of executeSynchronously or executeFenced.
+ *
+ * An IExecution object is used to control a set of executions on the same prepared model with
+ * the same request and properties. IExecution objects enable some optimizations:
+ * (1) An IExecution object can preserve resources between executions. For example, a driver can
+ *     map a memory object when the IExecution object is created and cache the mapping for reuse in
+ *     subsequent executions. Any cached resource can be released when the IExecution object is
+ *     destroyed.
+ * (2) Because an IExecution object may be used for at most one execution at a time, any transient
+ *     execution resources such as intermediate tensors can be allocated once when the IExecution
+ *     object is created and freed when the IExecution object is destroyed.
+ * (3) An IExecution object is created for a fixed request. This enables the implementation to apply
+ *     request-specific optimizations. For example, an implementation can avoid request validation
+ *     and conversions when the IExecution object is reused. An implementation may also choose to
+ *     specialize the dynamic tensor shapes in the IExecution object according to the request.
