perf symbols: Add nr_events to symbol_conf

2011-11-28T12:37:11+00:00

Since symbol__alloc_hists need it, to avoid passing it around in many
functions have it in the symbol_conf struct.

perf annotate browser: Allow navigation to called functions

2011-10-07T20:00:09+00:00

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

2011-10-07T15:12:51+00:00

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

2011-09-29T20:10:00+00:00

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 top: Live TUI Annotation

2011-02-22T15:02:07+00:00

Now one has just to press the right key, 'a' or Enter on the main 'perf
top --tui' screen to live annotate the symbol under the cursor.

The annotate window starts centered on the hottest line (the one with
most samples so far) then TAB and shift+TAB can be used to go to the
prev/next hot line.

Pressing 'H' at any point will center again the screen on the hottest
line.

perf annotate: Fix annotate context lines regression

2011-02-08T17:29:25+00:00

The live annotation done in 'perf top' needs to limit the context before
lines that aren't filtered out by the min percent filter, if we don't do
that, the screen in a tty often is not enough for showing what is
interesting: lines with hits and a few source code lines before it.

perf annotate: Move locking to struct annotation

2011-02-08T17:03:36+00:00

Since we'll need it when implementing the live annotate TUI browser.

This also simplifies things a bit by having the list head for the source
code to be in the dynamicly allocated part of struct annotation, that
way we don't have to pass it around, it can be found from the struct
symbol that is passed everywhere.

perf annotate: Fix build error

2011-02-07T14:41:55+00:00

A small fix for when NO_NEWT_SUPPORT is defined.

Add a missing "struct" to the function prototype.

perf top: Ditch private annotation code, share perf annotate's

2011-02-06T18:08:50+00:00

Next step: Live TUI annotation in perf top, just press enter on a symbol
line.

perf annotate: Separate objdump parsing from actual screen rendering

2011-02-06T15:40:31+00:00

Because in 'perf top' we'll need to parse just once and then, as samples
come, render multiple times with evolving counter values.
