From 6ff7b996a8a4cf12e0d54110bb2db4c87f72e9f4 Mon Sep 17 00:00:00 2001 From: David Hunt Date: Tue, 8 Jan 2019 15:25:23 +0000 Subject: [PATCH] examples/power: fix for p-state The vm_power_manager starts by setting the environment to acpi using rte_power_set_env(PM_ENV_ACPI_CPUFREQ). This causes a problem starting vm_power_manager when the system is using the intel_pstate driver. The env should be set to none, or not called at all, because the library now auto-detects the environment to be either acpi or intel_pstate. This patch sets the environment to none so that the library can successfully auto-detect.
