perf hists browser: Add option for runtime switching perf data file

2013-02-06T21:09:24+00:00

Based on perf report/top/scripts browser integration idea from acme.

This will enable user to runtime switch the data file, when this option
is selected, it will popup all the legal data files in current working
directory, and the filename selected by user is saved in the global
variable "input_name", and a new key 'K_SWITCH_INPUT_DATA' will be
passed back to the built-in command which will perform the switch.

This initial version only enables it for 'perf report'.

v2: rebase to latest 'perf/core' branch (6e1d4dd) of acme's perf tree

perf report: Show group description when event group is enabled

2013-01-31T16:07:48+00:00

When using event group viewer, it's better to show the group description
rather than the leader information alone.

If a leader did not contain any member, it's a non-group event.

perf report: Bypass non-leader events when event group is enabled

2013-01-31T16:07:48+00:00

Since we have all necessary information in the leader events and other
members don't, bypass members.  Member events will be shown along with
the leaders if event group is enabled.

perf hists browser: Move coloring logic to hpp functions

2013-01-31T16:07:47+00:00

Move coloring logic into the hpp functions so that each value can
be colored independently.  It'd required for event group view.

For overhead column, add a callback for printing 'folded_sign' of
callchains of a hist entry.

perf hists browser: Convert hpp helpers to a function

2013-01-31T16:07:46+00:00

The hpp helpers do same job for each field so it was implemented as
macro in order to access those fields easily.  But it gets cumbersome
to maintain a large function in a macro as the function grows. Factor
it out to a function with a little helper macro to access field.

perf ui browsers: Fix usage of __ in struct names

2013-01-24T19:40:51+00:00

In tools/perf we use a convention where __ separates the struct name
from the function name for functions that operate on a struct instance.

Fix this usage by removing it from the struct names and fix also the
associated functions.

perf annotate browser: Fix segfault when drawing out-of-bounds jumps

2013-01-24T19:40:36+00:00

Factorize jump sanity checks from mark_jump_targets() and
draw_current_jump() in an is_valid_jump() function.

This fixes a segfault when moving the cursor over an invalid jump.

perf hists: Introduce perf_hpp__list for period related columns

2012-12-09T11:46:05+00:00

Adding perf_hpp__list list to register and contain all period related
columns the command is interested in.

This way we get rid of static array holding all possible columns and
enable commands to register their own columns.

It'll be handy for diff command in future to process and display data
for multiple files.

perf annotate: Don't try to follow jump target on PLT symbols

2012-11-09T19:23:21+00:00

The perf annotate browser on TUI can identify a jump target for a
selected instruction.  It assumes that the jump target is within the
function but it's not the case of PLT symbols which have offset out of
the function as a target.

Since it caused a segmentation fault, do not try to follow jump target
on the PLT symbols.
