Rename variables, add a comment and add a cpu_aggr_map__for_each_idx to aid the readability of the stat-display code. In particular, try to make sure aggr_idx is used consistently to differentiate from other kinds of index. Signed-off-by:

runtime_stat is only shared for the sake of tests that don't care about its value. Move the definition into stat-shadow.c and have the tests also use the global version. Signed-off-by:

Ian Rogers authored
The enums are only used in stat-shadow.c, so narrow their scope by moving to the C file. Signed-off-by:

perf_stat_evsel_id was used for hard coded metrics. These have now migrated to json metrics and so the id values are no longer necessary. Signed-off-by:

Rather than parsing events for --smi-cost, use the json metric group 'smi'. Signed-off-by:
-
Ian Rogers authored
The metric group "transaction" is now present for Intel architectures so the legacy hard coded approach won't be used. Remove the associated logic. Signed-off-by:

Ian Rogers authored
perf stat now supports --topdown for any platform with the TopdownL1 metric group including Intel before Icelake. Tweak the documentation to reflect this. Signed-off-by:

Now the events are computed from json metrics, the hard coded logic can be removed. Signed-off-by:
-
Ian Rogers authored
Request the topdown metric group of a level with the metrics in the group 'TopdownL<level>' rather than through specific events. As more topdown levels are supported this way, such as 6 on Intel Ice Lake, default to just showing the level 1 metrics. This can be overridden using '--td-level'. Rather than determine the maximum topdown level from sysfs, use the metric group names. Remove some now unused topdown code. Signed-off-by:
-
Ian Rogers authored
When there are no events and on Intel, the topdown events will be added by default if present. To display the metrics associated with these request special handling in stat-shadow.c. To more easily update these metrics use the json metric version via the TopdownL1 group. This makes the handling less platform specific. Modify the metricgroup__has_metric code to also cover metric groups. Signed-off-by:

Thresholds may need additional events, this can impact things like sharing groups of events to avoid multiplexing. Add a flag to make the threshold calculations optional. The threshold will still be computed if no additional events are necessary. Signed-off-by:
-
Ian Rogers authored
Comparison and logical operations on NAN won't ensure the result is NAN. Ensure NANs are propogated so that threshold expressions like "tma_fetch_latency > 0.1 & tma_frontend_bound > 0.15" don't yield a number when the components are NAN. Signed-off-by:

Ian Rogers authored
Compute the threshold metric and use it to color the metric value as red or green. The threshold expression is used to generate the set of events as the threshold may require additional events. A later patch make this behavior optional with a --metric-no-threshold flag. Signed-off-by:

Ian Rogers authored
Add to json output by default. For regular output, only enable with the --detail flag. Signed-off-by:

Test the correctness of metric thresholds by testing them all with the fake PMU logic. Signed-off-by:
-
Ian Rogers authored
Parse the metric threshold and add to the pmu-events.c file. The metric isn't parsed as the parser uses python's parser and will break the operator precedence. Signed-off-by:
-
Ian Rogers authored
rand (reverse and) is useful in the parsing of metric thresholds. Update the documentation on operator precedence to clarify the simple expression parser and python differences wrt binary/logical operators. Signed-off-by:

Encoding enums like '1\0' wastes a byte and could be '1' (no '\0' terminator) if the 0 case is '0', it also removes a branch for decompressing. Signed-off-by:
