Changes since V3:
- Move the full name (PMU + metricgroup name) generation from the metric
code to the output code. (Ian)
- Add default tags for Hisi hip08 L1 metrics (John)
- Some patches have been merged. Drop them from the V4.
Changes since V2:
- Fixes memory leak (Ian)
(Ian, I cannot reproduce the memory leak on all my machines. Please
check whether the fix works on your side. Thanks.)
- Add Reviewed-by tags for several patches.
Changes since V1:
- Remove EVSEL_EVENT_MASK and use the __evsel__match which is suggested
by Ian.
- Support TopdownL1 on both e-core and p-core of ADL in the default
mode. (Ian)
- Have separate patches for the modifications of metricgroup and output.
(Ian)
- Does 2nd sort for the Default metricgroup. Remove the logic of
changing the associated metric event. (Ian)
- Move all the metric related code to stat-shadow (Ian)
- Move the commong functions between stat+csv_output and stat+std_output
to the lib directory (Ian)
In the default mode, the current output of the metricgroup include both
events and metrics, which is not necessary and makes the output hard to
read. Also, different ARCHs (even different generations of the ARCH) may
have a different output format because of the different events in a
metrics.
The patch proposes a new output format which only outputting the value
of each metric and the metricgroup name. It can brings a clean and
consistent output format among ARCHs and generations.
The patches 1-2 introduce the new metricgroup output.
The patches 3-4 improve the tests to cover the default mode.
The patch 5 update the event list for Hisi hip08.
Here are some examples for the new output.

The metrics from the same metric group must be adjacent to each other in the metric list. But the metric_list_cmp() sorts metrics by the number of events. Add a new sort for the Default metricgroup, which sorts by default_metricgroup_name and metric_name. Add is_default in the struct metric_event to indicate that it's from the Default metricgroup. Store the displayed metricgroup name of the Default metricgroup into the metric expr for output.

Since different ARCHs (even different generations in the same ARCH) may use different events. The output also vary on different platforms. For a metricgroup, only outputting the value of each metric is good enough. Add a new field default_metricgroup in evsel to indicate an event of the default metricgroup. For those events, printout() should print the metricgroup name rather than each event. Add perf_stat__skip_metric_event() to skip the evsel in the Default metricgroup, if it's not running or not the metric event. Add print_metricgroup_header_t to pass the functions which print the display name of each metricgroup in the Default metricgroup. Support all three output methods. Factor out perf_stat__print_shadow_stats_metricgroup() to print out each metrics.

I once want to call the proposed display mode metricgroup-only mode or even metric-only mode. I think that's a proper name. But we already have a metric-only mode. That will only bring confusion. Since it's only used in the default mode, I use the default everywhere in the comments for now. But for the long term, I think we may want to base on this display mode to create a new metric-only mode to replace the current metric-only mode. Personally, I think there are some drawbacks of the current metric-only mode, e.g., - All the metrics are printed in one line. It may not be a problem for the JSON or CSV mode. But it's hard to read in the STD mode. - No metricgroup name. If two or more metrics are collected, all the metrics are mixed together. It's hard to tell which metrics belong to which metricgroup. - No parents-kids relation. We never have such feature. But it should be an useful improvement.
