| * 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. |
