Subject: [dpdk-dev] [PATCH v4 7/9] examples/vm_power: add branch ratio policy type
Date: Fri, 13 Jul 2018 15:23:00 +0100 [thread overview]
Message-ID: <20180713142302.34576-8-david.hunt@intel.com> (raw)
In-Reply-To: <20180713142302.34576-1-david.hunt@intel.com>
Add the capability for the vm_power_manager to receive
a policy of type BRANCH_RATIO. This will add any vcpus
in the policy to the oob monitoring thread.
Signed-off-by: David Hunt <david.hunt@intel.com>
