      perf tools: Support for DWARF CFI unwinding on post processing · 71ad0f5e
      由 Jiri Olsa 提交于 
      This brings the support for DWARF cfi unwinding on perf post
processing. Call frame informations are retrieved and then passed
to libunwind that requests memory and register content from the
applications.

Adding unwind object to handle the user stack backtrace based
on the user register values and user stack dump.

The unwind object access the libunwind via remote interface
and provides to it all the necessary data to unwind the stack.

The unwind interface provides following function:
	unwind__get_entries

And callback (specified in above function) to retrieve
the backtrace entries:
	typedef int (*unwind_entry_cb_t)(struct unwind_entry *entry,
					 void *arg);

      perf tools: Add libunwind dependency for DWARF CFI unwinding · 6a40cd90
      由 Jiri Olsa 提交于 
      Adding libunwind to be linked with perf if available. It's required
for the to get dwarf cfi unwinding support.

Also building perf with the dwarf call frame informations by default,
so that we can unwind callchains in perf itself.

Adding LIBUNWIND_DIR Makefile variable allowing user to specify
the directory with libunwind to be linked. This is used for
debug purposes.

Let's disable -Wredundant-decls for util/parse-events.c since it includes

      perf: Have perf use the new libtraceevent.a library · aaf045f7
      由 Steven Rostedt 提交于 
      The event parsing code in perf was originally copied from trace-cmd
but never was kept up-to-date with the changes that was done there.
The trace-cmd libtraceevent.a code is much more mature than what is
currently in perf.

This updates the code to use wrappers to handle the calls to the
new event parsing code. The new code requires a handle to be pass
around, which removes the global event variables and allows
more than one event structure to be read from different files
(and different machines).

But perf still has the old global events and the code throughout
perf does not yet have a nice way to pass around a handle.
A global 'pevent' has been made for perf and the old calls have
been created as wrappers to the new event parsing code that uses
the global pevent.

With this change, perf can later incorporate the pevent handle into
the perf structures and allow more than one file to be read and
compared, that contains different events.

      perf: Separate out trace-cmd parse-events from perf files · 4ace73ee
      由 Steven Rostedt 提交于 
      Move the trace-event-parse.c code that originally came from trace-cmd into
their own files. The new file will be called trace-parse-events.c, as
the name of trace-cmd's file was parse-events.c too, but it conflicted
with the parse-events.c file in perf that parses the command line.

This tries to update the code with mimimal changes.

Perf specific code stays in the trace-event-parse.[ch] files and
the common parsing code is now in trace-parse-events.c and
trace-parse-events.h.

      perf report: Add a simple GTK2-based 'perf report' browser · c31a9457
      由 Pekka Enberg 提交于 
      This patch adds a simple GTK2-based browser to 'perf report' that's
based on the TTY-based browser in builtin-report.c.

To launch "perf report" using the new GTK interface just type:

  $ perf report --gtk

The interface is somewhat limited in features at the moment:

  - No callgraph support

  - No KVM guest profiling support

  - No color coding for percentages

  - No sorting from the UI

  - ..and many, many more!

That said, I think this patch a reasonable start to build future features on.

      Adding pmu object which provides interface to pmu's sysfs
event format definition located at:
  ${sysfs_mount}/bus/event_source/devices/${pmu}/format

Following interface is exported:
  struct perf_pmu* perf_pmu__find(char *name);
  - this function returns pmu object, which is then
    passed as a handle to other interface functions

  int perf_pmu__config(struct perf_pmu *pmu, struct perf_event_attr *attr,
                       struct list_head *head_terms);
  - this function configures perf_event_attr struct based
    on pmu's format definitions and config terms data,
    containined in head_terms list.

Parser generator is used to retrive the pmu's format definition.
The generated parser is part of the patch. Added makefile rule
'pmu-parser' to generate the parser code out of the bison/flex
sources.

Added builtin test 'Test perf pmu format parsing', which could
be run like:
