perf c2c: Organize metrics based on memory hierarchy
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" Signed-off-by: Leo Yan <leo.yan@linaro.org> Tested-by: Joe Mario <jmario@redhat.com> Acked-by: Jiri Olsa <jolsa@redhat.com> Link: https://lore.kernel.org/r/20201014050921.5591-4-leo.yan@linaro.org Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
