/**
* DOC:
* The "Coarse" 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:
* - All Shader Cores are powered up, regardless of whether or not they will
* be needed later.
* - When KBase indicates that a set of Shader Cores are needed to submit the
* currently queued Job Chains:
* - All Shader Cores are kept powered, regardless of whether or not they will
* be needed
* - 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.
