Message-Id: <1388093679-26952-3-git-send-email-peter.p.waskiewicz.jr@intel.com> Date: Thu, 26 Dec 2013 13:34:38 -0800 From: Peter P Waskiewicz Jr <peter.p.waskiewicz.jr@...el.com> To: cgroups@...r.kernel.org, x86@...nel.org, tj@...nel.org Cc: linux-kernel@...r.kernel.org, peter.p.waskiewicz.jr@...el.com Subject: [RFC PATCH 2/3] x86: Add Cache QoS Monitoring support to x86 perf uncore This patch adds the MSRs and masks for CQM to the x86 uncore. The actual scheduling functions using the MSRs will be included in the next patch when the new cgroup subsystem is added, as there are dependencies on structs from the cgroup.
