This should be enough for diffs where the system is non
volatile, i.e. when one doesn't updates binaries.

For volatile environments, stay tuned for the next perf tool
feature: a buildid cache populated by 'perf record', managed by
'perf buildid-cache' a-la ccache, and used by all the report
tools.

      perf tools: Add support for breakpoint events in perf tools · 1b290d67
      由 Frederic Weisbecker 提交于 
      Add the breakpoint events support with this new sysnopsis:

  mem:addr[:access]

Where addr is a raw addr value in the kernel and access can be
either [r][w][x]

Example to profile tasklist_lock:

	$ grep tasklist_lock /proc/kallsyms
	ffffffff8189c000 D tasklist_lock

	$ perf record -e mem:0xffffffff8189c000:rw -a -f -c 1
	$ perf report

	# Samples: 62
	#
	# Overhead          Command  Shared Object  Symbol
	# ........  ...............  .............  ......
	#
	    29.03%          swapper  [kernel]       [k] _raw_read_trylock
	    29.03%          swapper  [kernel]       [k] _raw_read_unlock
	    19.35%             init  [kernel]       [k] _raw_read_trylock
	    19.35%             init  [kernel]       [k] _raw_read_unlock
	     1.61%         events/0  [kernel]       [k] _raw_read_trylock
	     1.61%         events/0  [kernel]       [k] _raw_read_unlock

Coming soon:

 - Support for symbols in the event definition.

 - Default period to 1 for breakpoint events because these are
   not high frequency events. The same thing is needed for trace
   events.

      perf buildid-list: New plumbing command · c34984b2

      With this we can list the buildids in a perf.data file so that
we can pipe them to other, distro specific tools that from the
buildids can figure out separate packages (foo-debuginfo) where
we can find the matching symtabs so that perf report can do its
job.

      perf timechart: Add a process filter · bbe2987b
      由 Arjan van de Ven 提交于 
      During the Kernel Summit demo of perf/ftrace/timechart, there
was a feature request to have a process filter for timechart so
that you can zoom into one or a few processes that you are
really interested in.

This patch adds basic support for this feature, the -p
(--process) option now can select a PID or a process name to be
shown. Multiple -p options are allowed, and the combined set
will be included in the output.

      perf timechart: Add a power-only mode · 39a90a8e
      由 Arjan van de Ven 提交于 
      For doing work on the Linux power management components, I need to
make long (30+ seconds) traces. Currently, this then results in a
HUGE svg file, with mostly process data that isn't interesting.

This patch adds a --power-only mode to perf timechart that only
outputs the CPU power section of the SVG; this significantly
reduces the size of the SVG file, making even 30+ second traces
viewable with inkscape.

As a minor tweak for the same effect, the minimum text size is
decreased; current inkscape cannot zoom in deep enough to show text
this small, but it reduces inkscape compute time.

      由 Arjan van de Ven 提交于 
      This patch adds a command line option for timechart that allows the
user to specify the width of the SVG file.

This patch also makes sure that each second of recording has at
least 200 units (pixels at 96 DPI) of width.  This impacts
recordings longer than 5 seconds; recordings shorter than 5 second
will scale up to have a width of 1000 units for the whole recording
(as before).

First baby step towards that goal: clone the new command off of
perf trace.

Fix a few other details along the way:

 - add (minimal) perf trace documentation

 - reorder a few places

 - list perf trace in the mainporcelain list as well
   as it's a very useful utility.

Also add these extra options to control the new behaviour:

  -w, --field-width

Force each column width to the provided list, for large terminal
readability.

  -t, --field-separator:

Use a special separator character and don't pad with spaces, replacing
all occurances of this separator in symbol names (and other output) with
a '.' character, that thus it's the only non valid separator.

      So that we can filter by symbol name.

The 'pfunct' utility in the 'dwarves' package can be used to
create a file with the functions one wants.

Example:

[acme@doppio pahole]$ pfunct /usr/lib/debug/usr/lib64/libdw-0.141.so.debug | grep dwarf > /tmp/dwarf.symbols
[acme@doppio pahole]$ wc -l /tmp/dwarf.symbols
93 /tmp/dwarf.symbols
[acme@doppio pahole]$ head -3 /tmp/dwarf.symbols
dwfl_addrdwarf
dwfl_module_getdwarf
dwfl_getdwarf
[acme@doppio pahole]$ perf report --sort comm,dso,symbol --comms pahole --dsos /usr/lib64/libdw-0.141.so --symbols file:///tmp/dwarf.symbols
