*
* Author(s): Thomas Richter <tmricht@linux.ibm.com>
*
* Auxiliary traces are collected during 'perf record' using rbd000 event.
* Several PERF_RECORD_XXX are generated during recording:
*
* PERF_RECORD_AUX:
* Records that new data landed in the AUX buffer part.
* PERF_RECORD_AUXTRACE:
* Defines auxtrace data. Followed by the actual data. The contents of
* the auxtrace data is dependent on the event and the CPU.
* This record is generated by perf record command. For details
* see Documentation/perf.data-file-format.txt.
* PERF_RECORD_AUXTRACE_INFO:
* Defines a table of contains for PERF_RECORD_AUXTRACE records. 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. The event processing is deferred until
* | later (see perf_session__process_user_event()).
* | Other timestamps (0 or -1) are handled immediately by
* | perf_session__deliver_event(). These are events generated at start up
* | of command perf record. They create PERF_RECORD_COMM and PERF_RECORD_MMAP*
* | records. They are needed to create a list of running processes and its
* | memory mappings and layout. They are needed at the beginning to enable
* | command perf report to create process trees and memory mappings.
* |

* |
* auxtrace__process_event()

* | synchronization between auxiliary trace data and the events on the
* | perf.data file.

* machine__deliver_event()
* | Handles the PERF_RECORD_XXX event. This depends on the record type.

*
*
* Deferred processing determined by perf_session__process_user_event() is
* finally processed when a PERF_RECORD_FINISHED_ROUND is encountered. These
* are generated during command perf record.
* The timestamp of PERF_RECORD_FINISHED_ROUND event is taken to process all

* Each event is now processed by calling perf_session__deliver_event().
* This enables time synchronization between the data in the perf.data file and
