[CAUTION: External Email]
Trying to enable turbo boost on EPYC 7713 with this APIS:

  rte_power_init(lcore)
  rte_power_freq_enable_turbo(lcore)
 rte_power_freq_max(lcore)

 I receive this messages:

DPDK:POWER: Env isn't set yet!
DPDK:POWER: Attempting to initialise ACPI cpufreq power management...
DPDK:POWER: Power management governor of lcore 99 has been set to 'userspace' successfully
DPDK:POWER: Initialized successfully for lcore 99 power management
DPDK:POWER: Failed to enable turbo on lcore 99
