Moved the current librte_power implementation to rte_power_acpi_cpufreq, with renaming of functions only. Added rte_power_kvm_vm implementation to support Power Management from a VM. librte_power now hides the implementation based on the environment used. A new call rte_power_set_env() can explicidly set the environment, if not called then auto-detection takes place. rte_power_kvm_vm is subset of the librte_power APIs, the following is supported: rte_power_init(unsigned lcore_id) rte_power_exit(unsigned lcore_id) rte_power_freq_up(unsigned lcore_id) rte_power_freq_down(unsigned lcore_id) rte_power_freq_min(unsigned lcore_id) rte_power_freq_max(unsigned lcore_id) The other unsupported APIs return -ENOTSUP Signed-off-by: Alan Carew <alan.carew@intel.com> Signed-off-by: Pablo de Lara <pablo.de.lara.guarch@intel.com>
