I will try it > In another email, you said that your system is arm64. The pstate mode won't work on that (it's an Intel-specific driver, after all), and i'm not sure if ACPI would work either, we never tested it on arm64 and i'm not even sure it's _supposed to_ work. The librte_power library has always been IA-specific. I have a sneaking suspicion that you too are attempting to use l3fwd-power to test interrupts, rather than the librte_power library. Is that the case? -- Thanks, Anatoly
