[PATCH v2] powercap/rapl: handle domain energy unit

2015-03-13 Thread Jacob Pan
The current driver assumes all RAPL domains within a CPU package have the same energy unit. This is no longer true for HSW server CPUs since DRAM domain has is own fixed energy unit which can be different than the package energy unit enumerated by package power MSR. In fact, the default HSW EP pack
