power: common interface for guest and host 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> 2014-11-25 16:18:08 +00:00			`*/`

power: add environment capability probing Currently, there is no way to know if the power management env is supported without trying to initialize it. The init API also does not distinguish between failure due to some error and failure due to power management not being available on the platform in the first place. Thus, add an API that provides capability of probing support for a specific power management API.
