Thomas Gleixner 9de8d68695 perf/x86/intel/rapl: Convert it to a per package facility ... RAPL is a per package facility and we already have a mechanism for a dedicated per package reader. So there is no point to have multiple CPUs doing the same. The current implementation actually starts two timers on two CPUs if one does: perf stat -C1,2 -e -e power/energy-pkg .... which makes the whole concept of 1 reader per package moot. What's worse is that the above returns the double of the actual energy consumption, but that's a different problem to address and cannot be solved by removing the pointless per cpuness of that mechanism.
