Maybe mention why it's supposed to be not NULL in comments here. Also, i have a suspicion that the message is wrong - why would status be null if the environment was initialized? Presumably it's the other way around? > + goto fail_all; > + } > + if (rte_power_freq_enable_turbo == NULL) { > + printf("rte_power_freq_enable_turbo should not be NULL, environment has not " > + "been initialised\n"); > + goto fail_all; > + } > + if (rte_power_freq_disable_turbo == NULL) { > + printf("rte_power_freq_disable_turbo should not be NULL, environment has not " > + "been initialised\n"); > + goto fail_all; > + } > > ret = rte_power_exit(TEST_POWER_LCORE_ID); > if (ret < 0) { > @@ -502,6 +570,10 @@ test_power_cpufreq(void) > if (ret < 0) > goto fail_all; > > + ret = check_power_turbo(); > + if (ret < 0) > + goto fail_all; > + > ret = rte_power_exit(TEST_POWER_LCORE_ID); > if (ret < 0) { > printf("Cannot exit power management for lcore %u\n", > -- Thanks, Anatoly
