[RFC PATCH v8 5/7] perf stat: Add retire latency print functions to print out at the very end of print out

There is a newer version of this series
[RFC PATCH v8 5/7] perf stat: Add retire latency print functions to print out at the very end of print out
Posted by weilin.wang@intel.com 1 year, 9 months ago 
From: Weilin Wang <weilin.wang@intel.com>

Add print out functions so that users could read retire latency values.

Example output:

 Performance counter stats for 'system wide':

            25,717      MEM_INST_RETIRED.SPLIT_STORES    #      2.2 %  tma_split_stores
        28,365,080      CPU_CLK_UNHALTED.THREAD
             24.00      MEM_INST_RETIRED.SPLIT_STORES:R  #       96        4

       2.054365083 seconds time elapsed

This output of retire latency data is in format:
 <val> <event-name:R> # <sum> <count>.

My usual complaint that I hate the stat-display spaghetti code. We
keep putting more spaghetti on the plate and this change does this
too. In the evsel approach:
https://lore.kernel.org/lkml/20240428053616.1125891-1-irogers@google.com/
retirement latency events just update the counts for the event and so
we don't need to special case tpebs events like this. I'd prefer we
went that route. My reviewed-by no longer stands.

Thanks,
Ian

Based on the current stat-display code and the original TPEBS counting 
code, I believe the code in this commit and last commit was the best way to
do the metric calculation and printout. 

But I totally agree with you that if we could get evsel with retire latency work,
this code is not necessary.

I was thinking to plugin the retire latency value into evsel so that I could delete 
this and last commit. Do you think that would be a solution?
