Subject: [PATCH v1 2/8] perf c2c: Display "Total Stores" as a standalone metrics
Date: Wed, 14 Oct 2020 06:09:15 +0100 [thread overview]
Message-ID: <20201014050921.5591-3-leo.yan@linaro.org> (raw)
In-Reply-To: <20201014050921.5591-1-leo.yan@linaro.org>
The total stores is displayed under the metrics "Store Reference", to
output the same format with total records and all loads, extract the
total stores number as a standalone metrics "Total Stores".
After this patch, the tool shows the summary numbers ("Total records",
"Total loads", "Total Stores") in the unified form.
