Subject: [dpdk-dev] [PATCH v3 03/10] CPU Frequency Power Management(Host).
Date: Mon, 29 Sep 2014 16:18:16 +0100	[thread overview]
Message-ID: <1412003903-9061-4-git-send-email-alan.carew@intel.com> (raw)
In-Reply-To: <1412003903-9061-1-git-send-email-alan.carew@intel.com>

A wrapper around librte_power(using ACPI cpufreq), providing locking around the
non-threadsafe library, allowing for frequency changes based on core masks and
core numbers from both the CLI thread and epoll monitor thread.
