The android performance hint manager class (https://developer.android.com/ndk/reference/group/a-performance-hint ) allows us to configure various properties of our expected per-frame workloads to help the OS more accurlatly allocate resources (not sure what this means, assuming fast/slow core and/or throttling).

The way this API works is that we can, for each thread, create a sesssion and at the beginning set the target work duration - and at the end set the actual work duration.

in psuedocode:

var session = createSession(this_thread);
session.setTargetWorkDuration(Duration(..));
// Do Work
session.setActualWorkDuration(..).

However, we do not have accurate estimates of the target work duration because this work depends on completely arbitrary workloads created by SDK users. As a result we'd only ever be able to provide the actual work duration. But the OS already knows the actual work duration.
