help | |
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. |
