Right now that means that pressing the left arrow willl make the symbol annotation window to exit back to the main symbol histogram browser. This is another improvement on the UI fastpath, i.e. just the arrows and enter are enough for most browsing.

After we use the filters to zoom into DSOs or threads, we can use <- (left arrow) to zoom out from the last filter applied. It is still possible to zoom out of order by using the popup menu. With this we now have the zoom out operation on the browsing fast path, by allowing fast navigation using just the four arrors and the enter key to expand collapse callchains.

Number of samples is meaningless after we switched to auto-freq, so report the number of events, i.e. not the sum of the different periods, but the number PERF_RECORD_SAMPLE emitted by the kernel. While doing this I noticed that naming "count" to the sum of all the event periods can be confusing, so rename it to .period, just like in struct sample.data, so that we become more consistent. This helps with the next step, that was to record in struct hist_entry the number of sample events for each instance, we need that because we use it to generate the number of events when applying filters to the tree of hist entries like it is being done in the TUI report browser.

The events_stats.total field is too generic, rename it to .total_period, and also add a comment explaining that it is the sum of all the .period fields in samples, that is needed because we use auto-freq to avoid sampling artifacts. Ditto for events_stats.lost, that is the sum of all lost_event.lost fields, i.e. the number of events the kernel dropped. Looking at the users, builtin-sched.c can make use of these fields and stop doing it again.

Now we don't anymore use popen to run 'perf annotate' for the selected symbol, instead we collect per address samplings when processing samples in 'perf report' if we're using the newt browser, then we use this data directly to do annotation. Done this way we can actually traverse the objdump_line objects directly, matching the addresses to the collected samples and colouring them appropriately using lower level slang routines. The new ui_browser class will be reused for the main, callchain aware, histogram browser, when it will be made generic and don't assume that the objects are always instances of the objdump_line class maintained using list_heads.

Initially this was just to be able to have a printf like method to prepare the formatted string and then pass to newtPushHelpLine, but as we already have for ui_progress, etc, its a step in identifying a restricted, highlevel set of widgets we can then have implementations for multiple widget sets (GTK, etc).

Clicking on -> will bring as one of the popup menu options a "Zoom into CURRENT DSO", i.e. CURRENT will be replaced by the name of the DSO in the current line. Choosing this option will filter out all samples that didn't took place in a symbol in this DSO. After that the option reverts to "Zoom out of CURRENT DSO", to allow going back to the more compreensive view, not filtered by DSO. Future similar operations will include zooming into a particular thread, COMM, CPU, "last minute", "last N usecs", etc. Cc: Frédéric Weisbecker <fweisbec@gmail.com> Cc: Mike Galbraith <efault@gmx.de> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Paul Mackerras <paulus@samba.org> LKML-Reference: <new-submission> Signed-off-by: NArnaldo Carvalho de Melo <acme@redhat.com>

Then hist_entry__fprintf will just us the newly introduced hist_entry__snprintf, add the newline and fprintf it to the supplied FILE descriptor. This allows us to remove the use_browser checking in the color_printf routines, that now got color_snprintf variants too. The newt TUI browser (and other GUIs that may come in the future) don't have to worry about stdio specific stuff in the strings they get from the se->snprintf routines and instead use whatever means to do the equivalent. Also the newt TUI browser don't have to use the fmemopen() hack, instead it can use the se->snprintf routines directly. For now tho use the hist_entry__snprintf routine to reduce the patch size.

For when we are processing the events and inserting the entries in the browser. Experimentation here: naming "ui_something" we may be treading into creating a TUI/GUI set of routines that can then be implemented in terms of multiple backends. Also the time it takes for adding things to the "browser" takes, visually (I guess I should do some profiling here ;-) ), more time than for processing the events... That means we probably need to create a custom hist_entry browser, so that we reuse the structures we have in place instead of duplicating them in newt. But progress was made and at least we can see something while long files are being loaded, that must be one of UI 101 bullet points :-) Cc: Frédéric Weisbecker <fweisbec@gmail.com> Cc: Mike Galbraith <efault@gmx.de> Cc: Peter Zijlstra <a.p.zijlstra@chello.nl> Cc: Paul Mackerras <paulus@samba.org> Signed-off-by: NArnaldo Carvalho de Melo <acme@redhat.com>

Starts collapsed, allows annotating by pressing 'A' or 'a' on the symbol, be it the top level one or any of the symbols in the chains. It (ab)uses the only tree widget in newt, that is actually a checkbox tree that we use with just one option ('.'), end result is usable but we really need to create a custom widget tree so that we can use the data structures we have (hist_entry rb_tree + callchain rb_tree + lists), so that we reduce the memory footprint by not creating a mirror set of data structures in the newtCheckboxTree widget. Thanks to Frédéric Weisbacker for fixing the orphanage problem in 301fde27, without that we were tripping a newt bug (fix already sent to newt's maintainer).

Newt has widespread availability and provides a rather simple API as can be seen by the size of this patch. The work needed to support it will benefit other frontends too. In this initial patch it just checks if the output is a tty, if not it falls back to the previous behaviour, also if newt-devel/libnewt-dev is not installed the previous behaviour is maintaned. Pressing enter on a symbol will annotate it, ESC in the annotation window will return to the report symbol list. More work will be done to remove the special casing in color_fprintf, stop using fmemopen/FILE in the printing of hist_entries, etc. Also the annotation doesn't need to be done via spawning "perf annotate" and then browsing its output, we can do better by calling directly the builtin-annotate.c functions, that would then be moved to tools/perf/util/annotate.c and shared with perf top, etc But lets go by baby steps, this patch already improves perf usability by allowing to quickly do annotations on symbols from the report screen and provides a first experimentation with libnewt/TUI integration of tools. Tested on RHEL5 and Fedora12 X86_64 and on Debian PARISC64 to browse a perf.data file collected on a Fedora12 x86_64 box.
