The Energy Model (EM) can store power values in milli-Watts or in abstract
scale. This might cause issues in the subsystems which use the EM for
estimating the device power, such as:
- mixing of different scales in a subsystem which uses multiple
(cooling) devices (e.g. thermal Intelligent Power Allocation (IPA))
- assuming that energy [milli-Joules] can be derived from the EM power
values which might not be possible since the power scale doesn't have
to be in milli-Watts
To avoid misconfiguration add the requisite documentation to the EM and
related subsystems: EAS and IPA.
