| help |
| ACPI 5.0+ spec defines a generic mode of communication |
| between the OS and a platform such as the BMC. This medium |
| (PCC) is typically used by CPPC (ACPI CPU Performance management), |
| RAS (ACPI reliability protocol) and MPST (ACPI Memory power |
| states). Select this driver if your platform implements the |
| PCC clients mentioned above. |
