Intel CPUs from SandyBridge and newer have MSRs that allow to get an accurate energy consumption (Measured in micro joules). These are visible to the kernel (RAPL - Running average power limit). Is there an equivalent option for ARM CPUs?

  • you are talking about intel chips vs foundry independent IP. Two completely different things. Need to ask about a specific chip. Intels are a bit of a power hog so power measurements make sense. Wonder if you really need that for arm based chips. – old_timer Sep 16 '17 at 21:58
  • granted the processor is only part of the power consumption of the system. are you only interested in the main chip or the system? – old_timer Sep 16 '17 at 21:59
  • Yes. I am interested in the effect of workloads specifically on the CPU. Intel RAPL gives a very accurate read even on low power chips. Are there _any_ ARM based chips that implement something similar? – amanusk Sep 17 '17 at 06:55

    You need to go and read the documentation on these chips to find out. – old_timer Sep 17 '17 at 13:21
