That's fantastic:

# sudo cpupower -c 99 frequency-info info
analyzing CPU 99:

CPUs which run at the same hardware frequency: 99
CPUs which need to have their frequency coordinated by software: 99
maximum transition latency: Cannot determine or is not supported.
hardware limits: 1.50 GHz - 3.72 GHz
available frequency steps: 2.00 GHz, 1.70 GHz, 1.50 GHz

Subject: AMD EPYC 7713 64-Core: cannot enable turbo boost

[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
