perf tools: Check perf.data owner

2009-08-19T13:25:51+00:00

Add an owner check to opening perf.data files and a switch to
silence it.

Because perf-report/perf-annotate are binary parsers reading
another users' perf.data file could be a security risk if the
file were explicitly engineered to trigger bugs in the parser
(we hope of course there are non such bugs, but you never
know).

perf tools: Make 'make html' work

2009-08-18T16:43:13+00:00

pushd tools/perf/Documentation
make html
popd

is failing for me...

    ASCIIDOC perf-annotate.html
ERROR: unsafe: include file: /etc/asciidoc/./stylesheets/xhtml11.css
ERROR: unsafe: include file:
/etc/asciidoc/./stylesheets/xhtml11-manpage.css
ERROR: unsafe: include file:
/etc/asciidoc/./stylesheets/xhtml11-quirks.css
make: *** [perf-annotate.html] Error 1

Apparently asciidoc "unsafe" is the default mode of operation
in practice.

https://bugzilla.redhat.com/show_bug.cgi?id=506953

Works tidily now.

perf annotate: Fix segmentation fault

2009-08-18T12:00:52+00:00

Linus reported this perf annotate segfault:

        [torvalds@nehalem git]$ perf annotate unmap_vmas
        Segmentation fault

       	#0  map__clone (self=) at builtin-annotate.c:236
       	#1  thread__fork (self=) at builtin-annotate.c:372

The bug here was that builtin-annotate.c was a copy of
builtin-report.c and a threading related fix to builtin-report.c
didnt get propagated to builtin-annotate.c ...

perf: Rename perf-examples.txt to examples.txt

2009-08-17T08:43:42+00:00

Rename it to examples.txt to avoid the perf-*.txt pattern in
the Makefile, otherwise 'make doc' fails because
perf-examples.txt is not formatted to be a man page:

 ERROR: perf-examples.txt: line 1: manpage document title is mandatory

perf record: Fix typo in pid_synthesize_comm_event

2009-08-15T09:59:06+00:00

We were using 'fd' locally, but there was a global 'fd' too, so
when converting from open to fopen the test made against fd
should be made against 'fp', but since we have that global
it didnt get discovered ...

perf report: Don't show unresolved DSOs and symbols when -S/-d is used

2009-08-13T10:05:52+00:00

We're interested in just those symbols/DSOs, so filter out the
unresolved ones.

perf tools: Add a general option to enable raw sample records

2009-08-13T08:37:25+00:00

While we can enable the perf sample records per tracepoint
counter, we may also want to enable this option for every
tracepoint counters to open, so that we don't need to add a
:record flag for all of them.

Add the -R, --raw-samples options for this purpose.

perf tools: Add a per tracepoint counter attribute to get raw sample

2009-08-13T08:37:25+00:00

Add a new flag field while opening a tracepoint perf counter:

	-e tracepoint_subsystem:tracepoint_name:flags

This is intended to be generic although for now it only supports the
r[e[c[o[r[d]]]]] flag:

	./perf record -e workqueue:workqueue_insertion:record
	./perf record -e workqueue:workqueue_insertion:r

will have the same effect: enabling the raw samples record for
the given tracepoint counter.

In the future, we may want to support further flags, separated
by commas.

perf list: Fix large list output by using the pager

2009-08-13T07:05:48+00:00

When /sys/kernel/debug is mounted the list can be imense, so
use the pager like the other tools.

perf record: Add missing -C option support for specifying profile cpu

2009-08-12T12:10:51+00:00

perf top supports a -C for setting the profile CPU, but perf
record does not. This adds the same option for perf record,
allowing the user to specify a specific target profile CPU.
