| Select this option to enable the AMD Heterogeneous Core Hardware |
| Feedback Interface. If selected, hardware provides runtime thread |
| classification guidance to the operating system on the performance and |
| energy efficiency capabilities of each heterogeneous CPU core. These |
| capabilities may vary due to the inherent differences in the core types |
| and can also change as a result of variations in the operating |
| conditions of the system such as power and thermal limits. |
