/**
|
* DOC: Demand power management policy
|
*
|
* The demand power management policy has the following characteristics:
|
* - When KBase indicates that the GPU will be powered up, but we don't yet
|
* know which Job Chains are to be run:
|
* - The Shader Cores are not powered up
|
*
|
* - When KBase indicates that a set of Shader Cores are needed to submit the
|
* currently queued Job Chains:
|
* - Only those Shader Cores are powered up
|
*
|
* - When KBase indicates that the GPU need not be powered:
|
* - The Shader Cores are powered off, and the GPU itself is powered off too.
|
*
|
* Note:
|
* - KBase indicates the GPU will be powered up when it has a User Process that
|
* has just started to submit Job Chains.
|
*
|
* - KBase indicates the GPU need not be powered when all the Job Chains from
|
* User Processes have finished, and it is waiting for a User Process to
|
* submit some more Job Chains.
