perf tools: Add --tui and --stdio to choose the UI

2010-08-21T13:49:46+00:00

Relying just on ~/.perfconfig or rebuilding the tool disabling support
for the TUI is too cumbersome, so allow specifying which UI to use and
make the command line switch override whatever is in ~/.perfconfig.

perf ui browser: Return the exit key in all browsers

2010-08-19T22:39:52+00:00

Make all browsers return the exit key uniformly and remove the
newtExitStruct parameter, removing one more newt specific thing from the
ui API.

perf annotate: Sort by hottest lines in the TUI

2010-08-10T19:11:42+00:00

Right now it will just sort and position at the hottest line, i.e.
the one where more samples were taken.

It will be at the center of the screen and later TAB/shift-TAB will
cycle thru the hottest lines.

perf tools: Make event__preprocess_sample parse the sample

2010-06-05T12:35:19+00:00

Simplifying the tools that were using both in sequence and allowing
upcoming simplifications, such as Arun's patch to sort by cpus.

perf tui: Reset use_browser if stdout is not a tty

2010-05-26T16:22:26+00:00

The newt initialization routines weren't being called because the output
was a file (perf annotate > /tmp/bla) but use_browser was still 1,
because ~/.perfconfig had it as 'on', so, later on newt routines
segfaulted.

perf annotate: Add TUI interface

2010-05-22T14:25:40+00:00

When annotating multiple entries, for instance, when running simply as:

$ perf annotate

the right and left keys, as well as TAB can be used to cycle thru the
multiple symbols being annotated.

If one doesn't like TUI annotate, disable it by editing ~/.perfconfig
and adding:

[tui]

	annotate = off

Just like it is possible for report.

perf hist: Make event__totals per hists

2010-05-14T13:36:42+00:00

This is one more thing that started global but are more useful per hist
or per session.

perf report: Librarize the annotation code and use it in the newt browser

2010-05-12T02:23:20+00:00

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.

perf hist: Introduce hists class and move lots of methods to it

2010-05-10T16:13:49+00:00

In cbbc79a we introduced support for multiple events by introducing a
new "event_stat_id" struct and then made several perf_session methods
receive a point to it instead of a pointer to perf_session, and kept the
event_stats and hists rb_tree in perf_session.

While working on the new newt based browser, I realised that it would be
better to introduce a new class, "hists" (short for "histograms"),
renaming the "event_stat_id" struct and the perf_session methods that
were really "hists" methods, as they manipulate only struct hists
members, not touching anything in the other perf_session members.

Other optimizations, such as calculating the maximum lenght of a symbol
name present in an hists instance will be possible as we add them,
avoiding a re-traversal just for finding that information.

The rationale for the name "hists" to replace "event_stat_id" is that we
may have multiple sets of hists for the same event_stat id, as, for
instance, the 'perf diff' tool has, so event stat id is not what
characterizes what this struct and the functions that manipulate it do.

perf hist: Simplify the insertion of new hist_entry instances

2010-05-09T16:10:39+00:00

And with that fix at least one bug:

The first hit for an entry, the one that calls malloc to create a new
instance in __perf_session__add_hist_entry, wasn't adding the count to
the per cpumode (PERF_RECORD_MISC_USER, etc) total variable.
