That's fantastic:# sudo cpupower -c 99 frequency-info info
analyzing CPU 99:
driver: acpi-cpufreq
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
available cpufreq governors: conservative ondemand userspace powersave performance schedutil
current policy: frequency should be within 1.50 GHz and 3.72 GHz.
The governor "userspace" may decide which speed to use
within this range.
current CPU frequency: 2.00 GHz (asserted by call to hardware)

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:
