Pull perf updates from Ingo Molnar:
 "Kernel side changes:

   - Improve accuracy of perf/sched clock on x86.  (Adrian Hunter)

   - Intel DS and BTS updates.  (Alexander Shishkin)

   - Intel cstate PMU support.  (Kan Liang)

   - Add group read support to perf_event_read().  (Peter Zijlstra)

   - Branch call hardware sampling support, implemented on x86 and
     PowerPC.  (Stephane Eranian)

   - Event groups transactional interface enhancements.  (Sukadev
     Bhattiprolu)

   - Enable proper x86/intel/uncore PMU support on multi-segment PCI
     systems.  (Taku Izumi)

   - ... misc fixes and cleanups.

  The perf tooling team was very busy again with 200+ commits, the full
  diff doesn't fit into lkml size limits.  Here's an (incomplete) list
  of the tooling highlights:

  New features:

   - Change the default event used in all tools (record/top): use the
     most precise "cycles" hw counter available, i.e. when the user
     doesn't specify any event, it will try using cycles:ppp, cycles:pp,
     etc and fall back transparently until it finds a working counter.
     (Arnaldo Carvalho de Melo)

   - Integration of perf with eBPF that, given an eBPF .c source file
     (or .o file built for the 'bpf' target with clang), will get it
     automatically built, validated and loaded into the kernel via the
     sys_bpf syscall, which can then be used and seen using 'perf trace'
     and other tools.

     (Wang Nan)

  Various user interface improvements:

   - Automatic pager invocation on long help output.  (Namhyung Kim)

   - Search for more options when passing args to -h, e.g.: (Arnaldo
     Carvalho de Melo)

        $ perf report -h interface

        Usage: perf report [<options>]

         --gtk    Use the GTK2 interface
         --stdio  Use the stdio interface
         --tui    Use the TUI interface

   - Show ordered command line options when -h is used or when an
     unknown option is specified.  (Arnaldo Carvalho de Melo)

   - If options are passed after -h, show just its descriptions, not all
     options.  (Arnaldo Carvalho de Melo)

   - Implement column based horizontal scrolling in the hists browser
     (top, report), making it possible to use the TUI for things like
     'perf mem report' where there are many more columns than can fit in
     a terminal.  (Arnaldo Carvalho de Melo)

   - Enhance the error reporting of tracepoint event parsing, e.g.:

       $ oldperf record -e sched:sched_switc usleep 1
       event syntax error: 'sched:sched_switc'
                            \___ unknown tracepoint
       Run 'perf list' for a list of valid events

     Now we get the much nicer:

       $ perf record -e sched:sched_switc ls
       event syntax error: 'sched:sched_switc'
                            \___ can't access trace events

       Error: No permissions to read /sys/kernel/debug/tracing/events/sched/sched_switc
       Hint:  Try 'sudo mount -o remount,mode=755 /sys/kernel/debug'

     And after we have those mount point permissions fixed:

       $ perf record -e sched:sched_switc ls
       event syntax error: 'sched:sched_switc'
                            \___ unknown tracepoint

       Error: File /sys/kernel/debug/tracing/events/sched/sched_switc not found.
       Hint:  Perhaps this kernel misses some CONFIG_ setting to enable this feature?.

     I.e.  basically now the event parsing routing uses the strerror_open()
     routines introduced by and used in 'perf trace' work.  (Jiri Olsa)

   - Fail properly when pattern matching fails to find a tracepoint,
     i.e. '-e non:existent' was being correctly handled, with a proper
     error message about that not being a valid event, but '-e
     non:existent*' wasn't, fix it.  (Jiri Olsa)

   - Do event name substring search as last resort in 'perf list'.
     (Arnaldo Carvalho de Melo)

     E.g.:

       # perf list clock

       List of pre-defined events (to be used in -e):

        cpu-clock                                          [Software event]
        task-clock                                         [Software event]

        uncore_cbox_0/clockticks/                          [Kernel PMU event]
        uncore_cbox_1/clockticks/                          [Kernel PMU event]

        kvm:kvm_pvclock_update                             [Tracepoint event]
        kvm:kvm_update_master_clock                        [Tracepoint event]
        power:clock_disable                                [Tracepoint event]
        power:clock_enable                                 [Tracepoint event]
        power:clock_set_rate                               [Tracepoint event]

        syscalls:sys_enter_clock_getres                    [Tracepoint event]
        syscalls:sys_enter_clock_gettime                   [Tracepoint event]
        syscalls:sys_enter_clock_nanosleep                 [Tracepoint event]
        syscalls:sys_enter_clock_settime                   [Tracepoint event]

        syscalls:sys_exit_clock_settime                    [Tracepoint event]

  Intel PT hardware tracing enhancements:

   - Accept a zero --itrace period, meaning "as often as possible".  In
     the case of Intel PT that is the same as a period of 1 and a unit
     of 'instructions' (i.e.  --itrace=i1i).  (Adrian Hunter)

   - Harmonize itrace's synthesized callchains with the existing
     --max-stack tool option.  (Adrian Hunter)

   - Allow time to be displayed in nanoseconds in 'perf script'.
     (Adrian Hunter)

   - Fix potential infinite loop when handling Intel PT timestamps.
     (Adrian Hunter)

   - Slighly improve Intel PT debug logging.  (Adrian Hunter)

   - Warn when AUX data has been lost, just like when processing
     PERF_RECORD_LOST.  (Adrian Hunter)

   - Further document export-to-postgresql.py script.  (Adrian Hunter)

   - Add option to synthesize branch stack from auxtrace data.  (Adrian
     Hunter)

  Misc notable changes:

   - Switch the default callchain output mode to 'graph,0.5,caller', to
     make it look like the default for other tools, reducing the
     learning curve for people used to 'caller' based viewing.  (Arnaldo
     Carvalho de Melo)

   - various call chain usability enhancements.  (Namhyung Kim)

   - Introduce the 'P' event modifier, meaning 'max precision level,
     please', i.e.:

        $ perf record -e cycles:P usleep 1

     Is now similar to:

        $ perf record usleep 1

     Useful, for instance, when specifying multiple events.  (Jiri Olsa)

   - Add 'socket' sort entry, to sort by the processor socket in 'perf
     top' and 'perf report'.  (Kan Liang)

   - Introduce --socket-filter to 'perf report', for filtering by
     processor socket.  (Kan Liang)

   - Add new "Zoom into Processor Socket" operation in the perf hists
     browser, used in 'perf top' and 'perf report'.  (Kan Liang)

   - Allow probing on kmodules without DWARF.  (Masami Hiramatsu)

   - Fix 'perf probe -l' for probes added to kernel module functions.
     (Masami Hiramatsu)

   - Preparatory work for the 'perf stat record' feature that will allow
     generating perf.data files with counting data in addition to the
     sampling mode we have now (Jiri Olsa)

   - Update libtraceevent KVM plugin.  (Paolo Bonzini)

   - ... plus lots of other enhancements that I failed to list properly,

* Kernel pointers have redundant information, so we can use a

*
* This should be a per-architecture thing, to allow different
* error and pointer decisions.
*
* Userspace note:
* The same principle works for userspace, because 'error' pointers
* fall down to the unused hole far from user space, as described
* in Documentation/x86/x86_64/mm.txt for x86_64 arch:
*
* 0000000000000000 - 00007fffffffffff (=47 bits) user space, different per mm hole caused by [48:63] sign extension
* ffffffffffe00000 - ffffffffffffffff (=2 MB) unused hole
*

* This function implements a test that decodes a selection of instructions and

* instructions (i.e. intel_pt_get_insn()) is also checked.
*
* The instructions are originally in insn-x86-dat-src.c which has been
* processed by scripts gen-insn-x86-dat.sh and gen-insn-x86-dat.awk to produce
* insn-x86-dat-32.c and insn-x86-dat-64.c which are included into this program.
* i.e. to add new instructions to the test, edit insn-x86-dat-src.c, run the
* gen-insn-x86-dat.sh script, make perf, and then run the test.
*
* If the test passes %0 is returned, otherwise %-1 is returned. Use the
* verbose (-v) option to see all the instructions and whether or not they
* decoded successfuly.

#
# An example of using the database is provided by the script
# call-graph-from-postgresql.py. Refer to that script for details.
#
# Tables:
#
# The tables largely correspond to perf tools' data structures. They are largely self-explanatory.
#
# samples
#
# 'samples' is the main table. It represents what instruction was executing at a point in time
# when something (a selected event) happened. The memory address is the instruction pointer or 'ip'.
#
# calls
#
# 'calls' represents function calls and is related to 'samples' by 'call_id' and 'return_id'.
# 'calls' is only created when the 'calls' option to this script is specified.
#
# call_paths
#
# 'call_paths' represents all the call stacks. Each 'call' has an associated record in 'call_paths'.
# 'calls_paths' is only created when the 'calls' option to this script is specified.
#
# branch_types
#
# 'branch_types' provides descriptions for each type of branch.
#
# comm_threads
#
# 'comm_threads' shows how 'comms' relates to 'threads'.
#
# comms
#
# 'comms' contains a record for each 'comm' - the name given to the executable that is running.
#
# dsos
#
# 'dsos' contains a record for each executable file or library.
#
# machines
#
# 'machines' can be used to distinguish virtual machines if virtualization is supported.
#
# selected_events
#
# 'selected_events' contains a record for each kind of event that has been sampled.
#
# symbols
#
# 'symbols' contains a record for each symbol. Only symbols that have samples are present.
#
# threads
#
# 'threads' contains a record for each thread.
#
# Views:
#
# Most of the tables have views for more friendly display. The views are:
#
# calls_view
# call_paths_view
# comm_threads_view
# dsos_view
# machines_view
# samples_view
# symbols_view
# threads_view
#
# More examples of browsing the database with psql:
# Note that some of the examples are not the most optimal SQL query.
# Note that call information is only available if the script's 'calls' option has been used.
#
# Top 10 function calls (not aggregated by symbol):
#
# SELECT * FROM calls_view ORDER BY elapsed_time DESC LIMIT 10;
#
# Top 10 function calls (aggregated by symbol):
#
# SELECT symbol_id,(SELECT name FROM symbols WHERE id = symbol_id) AS symbol,
# SUM(elapsed_time) AS tot_elapsed_time,SUM(branch_count) AS tot_branch_count
# FROM calls_view GROUP BY symbol_id ORDER BY tot_elapsed_time DESC LIMIT 10;
#
# Note that the branch count gives a rough estimation of cpu usage, so functions
# that took a long time but have a relatively low branch count must have spent time
# waiting.
#
# Find symbols by pattern matching on part of the name (e.g. names containing 'alloc'):
#
# SELECT * FROM symbols_view WHERE name LIKE '%alloc%';
#
# Top 10 function calls for a specific symbol (e.g. whose symbol_id is 187):
#
# SELECT * FROM calls_view WHERE symbol_id = 187 ORDER BY elapsed_time DESC LIMIT 10;
#
# Show function calls made by function in the same context (i.e. same call path) (e.g. one with call_path_id 254):
#
# SELECT * FROM calls_view WHERE parent_call_path_id = 254;
#
# Show branches made during a function call (e.g. where call_id is 29357 and return_id is 29370 and tid is 29670)
#
# SELECT * FROM samples_view WHERE id >= 29357 AND id <= 29370 AND tid = 29670 AND event LIKE 'branches%';
#
# Show transactions:
#
# SELECT * FROM samples_view WHERE event = 'transactions';
#
# Note transaction start has 'in_tx' true whereas, transaction end has 'in_tx' false.
# Transaction aborts have branch_type_name 'transaction abort'
#
# Show transaction aborts:
#
# SELECT * FROM samples_view WHERE event = 'transactions' AND branch_type_name = 'transaction abort';
