Subject: [dpdk-dev] [PATCH v1 2/3] doc: add release note for power changes
Date: Thu, 2 May 2019 12:18:14 +0100 [thread overview]
Message-ID: <20190502111815.29343-2-david.hunt@intel.com> (raw)
In-Reply-To: <20190502111815.29343-1-david.hunt@intel.com>
In the Power Library, a new bit has been added to the mask returned by
rte_power_get_capabilities which indicates whether the core is an
Intel SST-BF high frequency core.
The Distributor sample app has also been enhanced to make use of SST-BF
cores, and pin relevant workloads to the higher frequency cores, if
available in the core mask provided to the application.
