Allow a legacy cache event to be both, for example, "L1-dcache-load-miss" and "cpu/L1-dcache-load-miss/" by introducing a new legacy cache term type. The term type is processed in config_term_pmu, setting both the type in perf_event_attr and the config. The code to determine the config is factored out of parse_events_add_cache and shared. If the PMU doesn't support legacy events, currently just core/hybrid PMUs do, then the term is treated like a PE_NAME term - as before. If only terms are being parsed, such as for perf_pmu__new_alias, then the PE_LEGACY_CACHE token is always parsed as PE_NAME. Signed-off-by:

The event parser needs to handle two special cases: 1) legacy events like L1-dcache-load-miss. These event names don't appear in JSON or sysfs, and lookup tables are used for the config value. 2) raw events where 'r0xead' is the same as 'read' unless the PMU has an event called 'read' in which case the event has priority. The previous parser to handle these cases would scan all PMUs for components of event names. These components would then be used to classify in the lexer whether the token should be part of a legacy event, a raw event or an event. The grammar would handle legacy event tokens or recombining the tokens back into a regular event name. The code wasn't PMU specific and had issues around events like AMD's branch-brs that would fail to parse as it expects brs to be a suffix on a legacy event style name: $ perf stat -e branch-brs true event syntax error: 'branch-brs' \___ parser error This change removes processing all PMUs by using the lexer in the form of a regular expression matcher. The lexer will return the token for the longest matched sequence of characters, and in the event of a tie the first. The legacy events are a fixed number of regular expressions, and by matching these before a name token its possible to generate an accurate legacy event token with everything else matching as a name. Because of the lexer change the handling of hyphens in the grammar can be removed as hyphens just become a part of the name. To handle raw events and terms the parser is changed to defer trying to evaluate whether something is a raw event until the PMU is known in the grammar. Once the PMU is known, the events of the PMU can be scanned for the 'read' style problem. A new term type is added for these raw terms, used to enable deferring the evaluation. While this change is large, it has stats of: 170 insertions(+), 436 deletions(-) the bulk of the change is deleting the old approach. It isn't possible to break apart the code added due to the dependencies on how the parts of the parsing work. Signed-off-by: -

The strlist in print_hwcache_events holds the event names as they are generated, and then it is iterated and printed. This is unnecessary and each event can just be printed as it is processed.

Ian Rogers authored
Opening hardware names and a legacy cache event on a hybrid PMU opens it on each PMU. Parsing and checking indexes fails, as the parsed index is double the expected. Avoid checking the index by just comparing the names immediately after the parse. This change removes hard coded hybrid logic and removes assumptions about the expansion of an event. On hybrid the PMUs may or may not support an event and so using a distance isn't a consistent solution. Reviewed-by:

If 'struct rq' isn't defined in lock_contention.bpf.c then the type for the 'runqueue' variable ends up being a forward declaration (BTF_KIND_FWD) while the kernel has it defined (BTF_KIND_STRUCT).

Pre 5.11 kernels don't support 'contextid1' and 'contextid2' so validation would be skipped. By adding an additional check for 'contextid', old kernels will still have validation done even though contextid would either be contextid1 or contextid2. Additionally now that it's possible to override options, an existing bug in the validation is revealed. 'val' is overwritten by the contextid1 validation, and re-used for contextid2 validation causing it to always fail. '!val || val != 0x4' is the same as 'val != 0x4' because 0 is also != 4, so that expression can be simplified and the temp variable not overwritten.

The script command does not support aggregation modes by itself although that can be achieved using post-processing scripts. Because of this, it does not allocate memory for aggregated event values. Upon running perf stat record, the aggregation mode is set in the perf data file. If the mode is AGGR_GLOBAL, the aggregated event values are accessed and this leads to a segmentation fault since these were never allocated to begin with. Set the mode to AGGR_NONE explicitly to avoid this. E.g. $ perf stat record -e cycles true $ perf script Before: Segmentation fault (core dumped) After: CPU THREAD VAL ENA RUN TIME EVENT -1 231919 162831 362069 362069 935289 cycles:u Fixes: 8b76a318 ("perf stat: Remove unused perf_counts.aggr field") Signed-off-by:

If we have a group of {cycles,faults} then we need the faults software event to appear to be on the same PMU as cycles so that we don't split the group in parse_events__sort_events_and_fix_groups. This case is relatively easy as cycles is the leader and will have a PMU name. In the reverse case, {faults,cycles} we still need faults to appear to have the PMU name of cycles but the old behavior is just to return "cpu". For hybrid this fails as cycles will be on "cpu_core" or "cpu_atom", causing faults to be split into a different group. Change the behavior for software events so that the whole group is searched for the named PMU. Signed-off-by: -
