| The Energy Aware Scheduler (EAS) used to rely on Energy Models | |
| (EMs) statically defined in the Device Tree. More recent | |
| versions of EAS now rely on the EM framework to get the power | |
| costs of CPUs. | |
| This driver reads old-style static EMs in DT and feeds them in | |
| the EM framework, hence enabling to use EAS on platforms with | |
| old DT files. Since EAS now uses only the active costs of CPUs, | |
| the cluster-related costs and idle-costs of the old EM are | |
| ignored. | |
| If in doubt, say N. |
