Subject: [PATCH 1/5] perf jevents: Support metric constraint
Date: Wed, 19 Feb 2020 11:08:36 -0800 [thread overview]
Message-ID: <1582139320-75181-2-git-send-email-kan.liang@linux.intel.com> (raw)
In-Reply-To: <1582139320-75181-1-git-send-email-kan.liang@linux.intel.com>
From: Kan Liang <kan.liang@linux.intel.com>
A new field "MetricConstraint" is introduced in JSON event list.
Extend jevents to parse the field and save the value in
metric_constraint.
