perf ui browser: Use libslang to read keys

2011-10-20T18:59:15Z

Just another step in stopping the use of libnewt in perf. Cc: David Ahern Cc: Frederic Weisbecker Cc: Mike Galbraith Cc: Paul Mackerras Cc: Peter Zijlstra Cc: Stephane Eranian Link: http://lkml.kernel.org/n/tip-uy6s534uqxq8tenh6s3k8ocj@git.kernel.org Signed-off-by: Arnaldo Carvalho de Melo

perf tools: Make --no-asm-raw the default

2011-10-07T20:01:32Z

And add the annotation output knobs to all the tools that have integrated annotation (top, report).

perf annotate browser: Allow navigation to called functions

2011-10-07T20:00:09Z

I.e. when in the annotate TUI window, if Enter is pressed over an assembly line with a 'callq' it will try to open another TUI window with that symbol. This is just a proof of concept and works only on x86_64, more work is needed to support kernel modules, userland, other arches, etc, but should already be useful as-is.

perf browsers: Add live mode to the hists, annotate browsers

2011-10-07T15:12:51Z

This allows passing a timer to be run periodically, which will update the hists tree that then gers refreshed on the screen, just like the Live mode (symbol entries, annotation) we already have in 'perf top --tui'. Will be used by the new hist_entry/hists based 'top' tool.

perf: Support setting the disassembler style

2011-09-29T20:10:00Z

Add -M option to report/annotate to pass directly to objdump. This allows to use -M intel for intel style disassembler syntax, which is useful for people who are very used to the Intel syntax.

perf annotate: Add --symfs option

2011-08-18T10:40:34Z

If you have --symfs in perf report, then you also need it for perf annotate. This allows off-box assembly level analysis of perf.data samples.

perf annotate: Make output more readable

2011-08-18T10:38:21Z

This patch adds two new options to perf annotate: - --no-asm-raw : Do not display raw instruction encodings - --no-source : Do not interleave source code with assembly code We believe those options make the output of annotate more readable. Systematically displaying source can make it hard to follow code and especially optimized code. Raw encodings are not useful in most cases.

perf report/annotate/script: Add option to specify a CPU range

2011-07-05T08:44:44Z

Add an option to perf report/annotate/script to specify which CPUs to operate on. This enables us to take a single system wide profile and analyse each CPU (or group of CPUs) in isolation. This was useful when profiling a multiprocess workload where the bottleneck was on one CPU but this was hidden in the overall profile. Per process and per thread breakdowns didn't help because multiple processes were running on each CPU and no single process consumed an entire CPU. The patch converts the list of CPUs returned by cpu_map__new into a bitmap for fast lookup. I wanted to use -C to be consistent with perf top/record/stat, but unfortunately perf report already uses -C . v2: Incorporate suggestions from David Ahern: - Added -c to perf script - Check that SAMPLE_CPU is set when -c is used - Update documentation v3: Create perf_session__cpu_bitmap() Signed-off-by: Anton Blanchard Acked-by: David Ahern Cc: Arnaldo Carvalho de Melo Cc: Peter Zijlstra Cc: Paul Mackerras Link: http://lkml.kernel.org/r/20110704215750.11647eb9@kryten Signed-off-by: Ingo Molnar

perf session: Pass evsel in event_ops->sample()

2011-03-23T22:28:58Z

Resolving the sample->id to an evsel since the most advanced tools, report and annotate, and the others will too when they evolve to properly support multi-event perf.data files. Good also because it does an extra validation, checking that the ID is valid when present. When that is not the case, the overhead is just a branch + function call (perf_evlist__id2evsel).
