27cf5706a0 perf sdt: Show proper hint when event not yet in place via 'perf probe' 
All events from 'perf list', except SDT events, can be directly recorded
with 'perf record'. But, the flow is little different for SDT events.

Probe points for SDT event needs to be created using 'perf probe' before
recording it using 'perf record'.

Perf shows misleading hint when a user tries to record SDT event without
first creating a probe point. Show proper hint there.

Before patch:

  $ perf record -a -e sdt_glib:idle__add
    event syntax error: 'sdt_glib:idle__add'
                         \___ unknown tracepoint

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

After patch:

  $ perf record -a -e sdt_glib:idle__add
    event syntax error: 'sdt_glib:idle__add'
                         \___ unknown tracepoint

    Error: File /sys/kernel/debug/tracing/events/sdt_glib/idle__add not found.
    Hint:  SDT event cannot be directly recorded on.
           Please first use 'perf probe sdt_glib:idle__add' before recording it.
    ...

  $ perf probe sdt_glib:idle__add
    Added new event:
      sdt_glib:idle__add   (on %idle__add in /usr/lib64/libglib-2.0.so.0.5000.2)

    You can now use it in all perf tools, such as:

        perf record -e sdt_glib:idle__add -aR sleep 1

  $ perf record -a -e sdt_glib:idle__add
    [ perf record: Woken up 1 times to write data ]
    [ perf record: Captured and wrote 0.175 MB perf.data ]

db49120a32 tools lib api fs: Use base 0 in filename__read_ull 
By using 0 for base, the strtoull() detects the base automatically (see
'man strtoull').

ATM we have just one user of this function, the cpu__get_max_freq
function reading the "cpuinfo_max_freq" sysfs file. It should not get
affected by this change.

Committer note:

This change seems motivated by this discussion:

"[PATCH] [RFC V1]s390/perf: fix 'start' address of module's map"
http://lkml.kernel.org/r/20160711120155.GA29929@krava

I.e. this patches paves the way for filename__read_ull() to be used in a
S/390 related fix.

dc240c5dc2 tools lib api fs: Store tracing mountpoint for better error message 
Storing the actual tracing path mountpoint to display correct

ab85785aa1 tools lib api debugfs: Check for tracefs when reporting errors 
Now that we have two mountpoints, one for debugfs and another, for
tracefs, we end up needing to check permissions for both, so, on
a system with default config we were always asking the user to
check the permission of the debugfs mountpoint, even when it was
already sufficient. Fix it.

E.g.:

  $ trace -e nanosleep usleep 1
  Error: No permissions to read /sys/kernel/debug/tracing/events/raw_syscalls/sys_(enter|exit)
  Hint:  Try 'sudo mount -o remount,mode=755 /sys/kernel/debug'

  $ sudo mount -o remount,mode=755 /sys/kernel/debug
  $ trace -e nanosleep usleep 1
  Error: No permissions to read /sys/kernel/debug/tracing/events/raw_syscalls/sys_(enter|exit)
  Hint:  Try 'sudo mount -o remount,mode=755 /sys/kernel/debug/tracing'

  $ sudo mount -o remount,mode=755 /sys/kernel/debug/tracing
  $ trace -e nanosleep usleep 1
     0.326 ( 0.061 ms): usleep/11961 nanosleep(rqtp: 0x7ffef1081c50) = 0
