This + * record is generated during 'perf record' command. Each record contains up + * to 256 entries describing offset and size of the AUXTRACE data in the + * perf.data file. + * PERF_RECORD_AUXTRACE_ERROR: + * Indicates an error during AUXTRACE collection such as buffer overflow. + * PERF_RECORD_FINISHED_ROUND: + * Perf events are not necessarily in time stamp order, as they can be + * collected in parallel on different CPUs. If the events should be + * processed in time order they need to be sorted first. + * Perf report guarantees that there is no reordering over a + * PERF_RECORD_FINISHED_ROUND boundary event. All perf records with a + * time stamp lower than this record are processed (and displayed) before + * the succeeding perf record are processed. + * + * These records are evaluated during perf report command. + * + * 1. PERF_RECORD_AUXTRACE_INFO is used to set up the infrastructure for + * auxiliary trace data processing. See s390_cpumsf_process_auxtrace_info() + * below. + * Auxiliary trace data is collected per CPU. To merge the data into the report + * an auxtrace_queue is created for each CPU. It is assumed that the auxtrace + * data is in ascending order. + * + * Each queue has a double linked list of auxtrace_buffers. This list contains + * the offset and size of a CPU's auxtrace data. During auxtrace processing + * the data portion is mmap()'ed. + * + * To sort the queues in chronological order, all queue access is controlled + * by the auxtrace_heap. This is basicly a stack, each stack element has two + * entries, the queue number and a time stamp. However the stack is sorted by + * the time stamps. The highest time stamp is at the bottom the lowest + * (nearest) time stamp is at the top. That sort order is maintained at all + * times! + * + * After the auxtrace infrastructure has been setup, the auxtrace queues are + * filled with data (offset/size pairs) and the auxtrace_heap is populated. + * + * 2. PERF_RECORD_XXX processing triggers access to the auxtrace_queues. + * Each record is handled by s390_cpumsf_process_event(). The time stamp of + * the perf record is compared with the time stamp located on the auxtrace_heap + * top element. If that time stamp is lower than the time stamp from the + * record sample, the auxtrace queues will be processed. As auxtrace queues + * control many auxtrace_buffers and each buffer can be quite large, the + * auxtrace buffer might be processed only partially. In this case the + * position in the auxtrace_buffer of that queue is remembered and the time + * stamp of the last processed entry of the auxtrace_buffer replaces the + * current auxtrace_heap top. + * + * 3. Auxtrace_queues might run of out data and are feeded by the + * PERF_RECORD_AUXTRACE handling, see s390_cpumsf_process_auxtrace_event(). + * + * Event Generation + * Each sampling-data entry in the auxilary trace data generates a perf sample. + * This sample is filled + * with data from the auxtrace such as PID/TID, instruction address, CPU state, + * etc. This sample is processed with perf_session__deliver_synth_event() to + * be included into the GUI. + * + * 4. PERF_RECORD_FINISHED_ROUND event is used to process all the remaining + * auxiliary traces entries until the time stamp of this record is reached + * auxtrace_heap top. This is triggered by ordered_event->deliver(). + * + * + * Perf event processing. + * Event processing of PERF_RECORD_XXX entries relies on time stamp entries. + * This is the function call sequence: + * + * __cmd_report() + * | + * perf_session__process_events() + * | + * __perf_session__process_events() + * | + * perf_session__process_event() + * | This functions splits the PERF_RECORD_XXX records. + * | - Those generated by perf record command (type number equal or higher + * | than PERF_RECORD_USER_TYPE_START) are handled by + * | perf_session__process_user_event(see below) + * | - Those generated by the kernel are handled by + * | perf_evlist__parse_sample_timestamp() + * | + * perf_evlist__parse_sample_timestamp() + * | Extract time stamp from sample data. + * | + * perf_session__queue_event() + * | If timestamp is positive the sample is entered into an ordered_event + * | list, sort order is the timestamp.
