perf maps: Merge 'struct maps' with 'struct map_groups'

2019-11-26T14:07:46+00:00

And pick the shortest name: 'struct maps'.

The split existed because we used to have two groups of maps, one for
functions and one for variables, but that only complicated things,
sometimes we needed to figure out what was at some address and then had
to first try it on the functions group and if that failed, fall back to
the variables one.

That split is long gone, so for quite a while we had only one struct
maps per struct map_groups, simplify things by combining those structs.

First patch is the minimum needed to merge both, follow up patches will
rename 'thread->mg' to 'thread->maps', etc.

perf report: Jump to symbol source view from total cycles view

2019-11-19T22:37:04+00:00

This patch supports jumping from tui total cycles view to symbol source
view.

For example,

  perf record -b ./div
  perf report --total-cycles

In total cycles view, we can select one entry and press 'a' or press
ENTER key to jump to symbol source view.

This patch also sets sort_order to NULL in cmd_report() which will use
the default branch sort order. The percent value in new annotate view
will be consistent with the percent in annotate view switched from perf
report (we observed the original percent gap with previous patches).

 v2:
 ---
 Fix the 'make NO_SLANG=1' error. (set __maybe_unused to
 annotation_opts in block_hists_tui_browse()).

perf util: Move block TUI function to ui browsers

2019-11-19T22:33:40+00:00

It would be nice if we could jump to the assembler/source view (like the
normal perf report) from total cycles view.

This patch moves the block_hists_tui_browse from block-info.c to
ui/browsers/hists.c in order to reuse some browser codes (i.e
do_annotate) for implementing new annotation view.

 v2:
 ---
 Fix the 'make NO_SLANG=1' error. (Change 'int block_hists_tui_browse()'
 to 'static inline int block_hists_tui_browse()')

perf annotate: Stop using map->groups, use map_symbol->mg instead

2019-11-12T11:20:53+00:00

These were the last uses of map->groups, next cset will nuke it.

pref tools: Make 'struct addr_map_symbol' contain 'struct map_symbol'

2019-11-12T11:20:53+00:00

So that we pass that substructure around and with it consolidate lots of
functions that receive a (map, symbol) pair and now can receive just a
'struct map_symbol' pointer.

This further paves the way to add 'struct map_groups' to 'struct
map_symbol' so that we can have all we need for annotation so that we
can ditch 'struct map'->groups, i.e. have the map_groups pointer in a
more central place, avoiding the pointer in the 'struct map' that have
tons of instances.

perf annotate: Pass a 'map_symbol' in places receiving a pair of 'map' and 'symbol' pointers

2019-11-12T11:20:53+00:00

We are already passing things like:

  symbol__annotate(ms->sym, ms->map, ...)

So shorten the signature of such functions to receive the 'map_symbol'
pointer.

This also paves the way to having the 'struct map_groups' pointer in the
'struct map_symbol' so that we can get rid of 'struct map'->groups.

perf report: Sort by sampled cycles percent per block for tui

2019-11-07T13:14:48+00:00

Previous patch has implemented a new option "--total-cycles".  But only
stdio mode is supported.

This patch supports the tui mode and support '--percent-limit'.

For example,

 perf record -b ./div
 perf report --total-cycles --percent-limit 1

--------------------------------------------------

 v7:
 ---
 1. Since we have used use_browser in report__browse_block_hists
    to support stdio mode, now we also add supporting for tui.

 2. Move block tui browser code from ui/browsers/hists.c
    to block-info.c.

 v6:
 ---
 Create report__tui_browse_block_hists in block-info.c
 (codes are moved from builtin-report.c).

 v5:
 ---
 Fix a crash issue when running perf report without
 '--total-cycles'. The issue is because the internal flag
 is renamed from 'total_cycles' to 'total_cycles_mode' in
 previous patch but this patch still uses 'total_cycles'
 to check if the '--total-cycles' option is enabled, which
 causes the code to be inconsistent.

 v4:
 ---
 Since the block collection is moved out of printing in
 previous patch, this patch is updated accordingly for
 tui supporting.

 v3:
 ---
 Minor change since the function name is changed:
 block_total_cycles_percent -> block_info__total_cycles_percent
