Linus,

please pull the latest perf-urgent-for-linus git tree from:

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git perf-urgent-for-linus

perf/core improvements and fixes:

Kernel:

- Improve kallsyms coverage
- Add x86 entry trampolines to kcore
- Fix ARM SPE handling
- Correct PPC event post processing

Tools:

- Make the build system more robust
- Small fixes and enhancements all over the place
- Update kernel ABI header copies
- Preparatory work for converting libtraceevnt to a shared library
- License cleanups

Thanks,

tglx

+ * 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.
+ * |
+ * perf_session__deliver_event()
+ * | Delivers a PERF_RECORD_XXX entry for handling.
