Subject: [PATCH 39/47] perf metricgroup: Scale the metric result
Date: Sun, 1 Sep 2019 09:23:18 -0300 [thread overview]
Message-ID: <20190901122326.5793-40-acme@kernel.org> (raw)
In-Reply-To: <20190901122326.5793-1-acme@kernel.org>
From: Jin Yao <yao.jin@linux.intel.com>
Some metrics define the scale unit, such as
{
"BriefDescription": "Intel Optane DC persistent memory read latency (ns). Derived from unc_m_pmm_rpq_occupancy.all",
"Counter": "0,1,2,3",
"EventCode": "0xE0",
"EventName": "UNC_M_PMM_READ_LATENCY",
"MetricExpr": "UNC_M_PMM_RPQ_OCCUPANCY.ALL / UNC_M_PMM_RPQ_INSERTS / UNC_M_CLOCKTICKS",
"MetricName": "UNC_M_PMM_READ_LATENCY",
"PerPkg": "1",
"ScaleUnit": "6000000000ns",
"UMask": "0x1",
"Unit": "iMC"
},
For above example, the ratio should be,
ratio = (UNC_M_PMM_RPQ_OCCUPANCY.ALL / UNC_M_PMM_RPQ_INSERTS / UNC_M_CLOCKTICKS) * 6000000000
But in current code, the ratio is not scaled ( * 6000000000)
With this patch, the ratio is scaled and the unit (ns) is printed.
For example,
# 219.4 ns UNC_M_PMM_READ_LATENCY
