This patch will add two elements for perf_tool struct: per_event_dump is used to mark the per-event-dump option, last_evsel_name is used to save last evsel's name. Add a new struct perf_script_evsel to save evsel's specific data. There are three elements in this new struct: dump_evsel_fp is used to save the file pointer of the dump_event file, filename is used to save the file name of the dump_event file, samples is used to save the number of samples for each evsel. The perf_script_evsel struct will be saved in the evsel->priv. Add the OPT_BOOLEAN for per-event-dump in the perf_data_file struct.
Changes since v4: - none. Changes since v3: - remove three elements for perf_evsel struct and create a new struct: perf_script_evsel to save them. Changes since v2: - add the last_evsel_name for per_tool struct to save last evsel's name. - add three elements for perf_evsel struct:dump_event_fp is used to save the file pointer of the dump_event file, filename is used to save the file name of the dump_event file, samples is used to save the number of samples for each evsel. Changes since v1: - remove the set for script.tool.per_event_dump variable,since the OPT_BOOLEAN will do the same thing.
