From: Steven Rostedt <rostedt@goodmis.org>
Add util/trace-event-info.c which handles ftrace file IO from debugfs
and provides general helpers to fetch/save ftrace events informations.
This file is a rename of the trace-cmd.c file from the trace-cmd tools,
written by Steven Rostedt and Josh Triplett, originated from the git
tree:
git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/trace-cmd.git
This is a perf tools integration.
For now, ftrace events informations are saved in a separate file than
the standard perf.data

From: Steven Rostedt <rostedt@goodmis.org>
Add util/trace-event-parse.c which provides the handlers to parse the
ftrace events info from the stream and handles the ftrace perf samples
event printing.
This file is a rename of the parse-events.c file from the trace-cmd tools,
written by Steven Rostedt and Josh Triplett, originated from the git
tree:
git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/trace-cmd.git
This is a perf tools integration.

This adds perf trace into the set of perf tools.
It is written to fetch the tracepoints samples from perf events and
display them, according to the events informations given by the debugfs
files through the util/trace* tools.
It is a rough first shot and doesn't yet handle the cpu, timestamps fields
and some other things.
Example:
perf record -f -e workqueue:workqueue_execution:record -F 1 -a
perf trace
kblockd/0-236 [000] 0.000000: workqueue_execution: thread=:236 func=cfq_kick_queue+0x0

heh :-)
To help this move forward i've put the patches into
tip:perfcounters/tracing. We might still rebase that branch, should
it become necessary, before merging it into perfcounters/core - but
it should give a first glimpse to people who want to try this.
A first bugreport:
took me some time to figure out that i need to pass in -R to create
a trace.info. I think we want to share the namespace anyway -
there's no real difference between perf.data and trace.info - both
contain trace records.
once i added -R i ran into this problem:
# perf record -R -f -e workqueue:workqueue_execution:record -F 1 -a
^C
[ perf record: Captured and wrote 0.250 MB perf.data (~10928 samples) ]
aldebaran:/home/mingo/linux/linux/tools/perf> perf trace
Fatal: bad op token )
version = 0.5
Some missing patch?

perf tools: Add trace event debugfs IO handler
Add util/trace-event-info.c which handles ftrace file IO from
debugfs and provides general helpers to fetch/save ftrace
events informations.
This file is a rename of the trace-cmd.c file from the
trace-cmd tools, written by Steven Rostedt and Josh Triplett,
originated from the git tree:
git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/trace-cmd.git
This is a perf tools integration.
For now, ftrace events information is saved in a separate file
than the standard perf.data

perf tools: Add trace event debugfs stream reader
Add util/trace-event-read.c which handles trace events
informations reading.
This file is a rename of the trace-read.c file from the
trace-cmd tools, written by Steven Rostedt and Josh Triplett,
originated from the git tree:
git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/trace-cmd.git
This is its perf tools integration.
[ fweisbec@gmail.com: various changes for perf tools
integration. ]

perf tools: Add trace event information parser
Add util/trace-event-parse.c which provides the handlers to
parse the ftrace events info from the stream and handles the
ftrace perf samples event printing.
This file is a rename of the parse-events.c file from the
trace-cmd tools, written by Steven Rostedt and Josh Triplett,
originated from the git tree:
git://git.kernel.org/pub/scm/linux/kernel/git/rostedt/trace-cmd.git
This is a perf tools integration.
[ fweisbec@gmail.com: various changes for perf tools
integration. ]

perf tools: Add perf trace
This adds perf trace into the set of perf tools.
It is written to fetch the tracepoint samples from perf events
and display them, according to the events information given by
the debugfs files through the util/trace* tools.
It is a rough first shot and doesn't yet handle the cpu,
timestamps fields and some other things.
Example:
perf record -f -e workqueue:workqueue_execution:record -F 1 -a
perf trace
kblockd/0-236 [000] 0.000000: workqueue_execution: thread=:236 func=cfq_kick_queue+0x0

trace.info only contains the events descriptions and other ftrace things:
- formats, ftrace printk strings, ...
I plan to integrate that into perf.trace so that we have only one file
to move to perform offline analysis.
Concerning the -R thing (or ::record suffix), indeed I have yet to
warn the user from perf trace about that. Todo listed!

Oh!
Hmm, also I forgot to explain a detail, there is a little bug in ftrace
syscalls formats which reports the format is too big when a syscall takes
no parameter. It needs a trivial fix, I'll send it soon.
Anyway, that made me a very similar Fatal thing but not exactly the same.
Could you send me your config? May be you have tracepoint/ftrace plugins
I haven't built (well I should build all of them actually).

./perf report -g
selected -c but no callchain data. Did you call perf record without -g?

You can enable a counter's PERF_SAMPLE_RAW attribute in two fashions:
- using the -R option (every counters get PERF_SAMPLE_RAW)
- using the :record suffix in a trace event counter name
Currently we record the events info in a trace.info file from perf
record when the former method is used but we omit it with the latter.
Check both situations.

The ftrace event format parser handles the usual casts but not the
cast to pointers. Such casts have been introduced recently with the
module trace events and raise the following parsing error:
Fatal: bad op token )
This is because it considers the "*" character as a binary operator.
Make it then aware of casts to pointers.

perf tools: Record events info also when :record suffix is used.
You can enable a counter's PERF_SAMPLE_RAW attribute in two
fashions:
- using the -R option (every counters get PERF_SAMPLE_RAW)
- using the :record suffix in a trace event counter name
Currently we record the events info in a trace.info file from
perf record when the former method is used but we omit it with
the latter.
Check both situations.

perf tools: Make trace event format parser aware of cast to pointers
The ftrace event format parser handles the usual casts but not
the cast to pointers. Such casts have been introduced recently
with the module trace events and raise the following parsing
error:
Fatal: bad op token )
This is because it considers the "*" character as a binary
operator. Make it then aware of casts to pointers.
