Subject: [RFC PATCH 05/12 v2] CONFIG for Workload Consolidation
Date: Mon, 12 May 2014 02:16:54 +0800 [thread overview]
Message-ID: <1399832221-8314-6-git-send-email-yuyang.du@intel.com> (raw)
In-Reply-To: <1399832221-8314-1-git-send-email-yuyang.du@intel.com>
Add CONFIG_WORKLOAD_CONSOLIDATION in arch/x86/Kconfig. This CONFIG enables
and disables CPU workload consolidation in scheduler's load balancing.
