perf annotate: Prefer passing evsel to evsel->core.idx

2025-01-18T18:02:10Z

An evsel idx may not be stable due to sorting, evlist removal, etc. Try to reduce it being part of APIs by explicitly passing the evsel in annotate code. Internally the code just reads evsel->core.idx so behavior is unchanged.

perf dso: Fix address sanitizer build

2024-07-12T16:38:41Z

Various files had been missed from having accessor functions added for the sake of dso reference count checking. Add the function calls and missing dso accessor functions.

perf annotate: Calculate instruction overhead using hashmap

2024-03-07T04:25:20Z

Use annotated_source.samples hashmap instead of addr array in the struct sym_hist.

perf annotate: Use global annotation_options

2023-12-07T20:17:57Z

Now it can directly use the global options and no need to pass it as an argument.

perf map: Add accessor for dso

2023-04-04T19:41:57Z

Later changes will add reference count checking for struct map, with dso being the most frequently accessed variable. Add an accessor so that the reference count check is only necessary in one place. Additional changes: - add a dso variable to avoid repeated map__dso calls. - in builtin-mem.c dump_raw_samples, code only partially tested for dso == NULL. Make the possibility of NULL consistent. - in thread.c thread__memcpy fix use of spaces and use tabs.

perf annotate: Add init/exit to annotation_options remove default

2023-04-04T12:39:56Z

The annotation__default_options global variable was used to initialize annotation_options. Switch to the init/exit pattern as later changes will give ownership over strings and this will be necessary to avoid memory leaks. Committer note: Fix the GTK2=1 build, hist_entry__gtk_annotate() needs to receive a 'struct annotation_options' pointer.

perf annotate: Re-add annotate_warned functionality

2021-08-03T20:04:04Z

Setting annotate_warned to true on errors was removed in commit ee51d851392e ("perf annotate: Introduce strerror for handling symbol__disassemble() errors") which means when 'perf annotate --skip-missing' is used warnings are shown multiple times for the same DSO. Setting this again restores the original behavior of only one warning each.

libperf: Move 'idx' from tools/perf to perf_evsel::idx

2021-07-09T17:04:28Z

Move evsel::idx to perf_evsel::idx, so we can move the group interface to libperf. Committer notes: Fixup evsel->idx usage in tools/perf/util/bpf_counter_cgroup.c, that appeared in my tree in my local tree. Also fixed up these: $ find tools/perf/ -name "*.[ch]" | xargs grep 'evsel->idx' tools/perf/ui/gtk/annotate.c: evsel->idx + i); tools/perf/ui/gtk/annotate.c: evsel->idx); $ That running 'make -C tools/perf build-test' caught.
