Hi all,

Hi Tomonori,

I cannot tell why init RAPL is failing. Can you give me your email, and I will send you some source code, so that we can investigate and make it work?

thank you martin [email protected]

Hello Martin,

  I am trying to use the Power Governor Tool on my machine It is a Haswell processor (Processor signature: 000306c3) with a Linux 14.04 (Kernel 4.4.0-51-generic). But when i run ./power_gov, the response is as follows:

Processor signature: 000306c3 RAPL not supported, or machine model not recognized. Init failed!

I am trying to change the power limits on the systems using power gov but it fails at Init(). Also i have posted a query on this forum regarding the LOCK bit of the MSR_PKG_POWERLIMIT register (Link: https://software.intel.com/en-us/forums/software-tuning-performance-optimization-platform-monitoring/topic/704976). Please help me out in this matter.

Thanks in advance,

Anmol
