Subject: [PATCH v1 3/8] perf c2c: Organize metrics based on memory hierarchy
Date:   Wed, 14 Oct 2020 06:09:16 +0100
Message-Id: <20201014050921.5591-4-leo.yan@linaro.org>
In-Reply-To: <20201014050921.5591-1-leo.yan@linaro.org>
References: <20201014050921.5591-1-leo.yan@linaro.org>
Precedence: bulk

The metrics are not organized based on memory hierarchy, e.g. the tool
doesn't organize the metrics order based on memory nodes from the close
node (e.g. L1/L2 cache) to far node (e.g. L3 cache and DRAM).

To output metrics with more friendly form, this patch refines the
metrics order based on memory hierarchy:

  "Core Load Hit" => "LLC Load Hit" => "LLC Ld Miss" => "Load Dram"
