Today I tried to use it to "autotest" the power DPDK subsystem but I fail to fully understand the feedback it gives (consider I've disable intel_pstate driver): For example: RTE>>power_autotest POWER: Invalid Power Management Environment(0) set RTE>>power_caps_autotest POWER: Env isn't set yet! POWER: Attempting to initialise ACPI cpufreq power management... POWER: Failed to write /sys/devices/system/cpu/cpu%u/cpufreq/scaling_governor POWER: Cannot set governor of lcore 2 to userspace POWER: Attempting to initialise PSTAT power management... POWER: Initialized successfully for lcore 2 power management POWER: Capabilities 1 How to fix the "Invalid Power Management Environment(0) set" and the Failed to write /sys/devices/system/cpu/cpu%u/cpufreq/scaling_governor ?
