daecf9e0fa perf tools: Add missing include for symbols.h
Several places were using definitions found in symbols.h but not
including it, getting it by sheer luck from some other headers that now
are in the process of removing that include because they don't need it
or because simply having struct forward declarations is enough, fix it.

1101f69af5 pref tools: Add missing map.h includes
Lots of places get the map.h file indirectly, and since we're going to
remove it from machine.h, then those need to include it directly, do it
now, before we remove that dep.

2eb3d6894a perf hist: Use cached rbtrees
At the cost of an extra pointer, we can avoid the O(logN) cost of
finding the first element in the tree (smallest node), which is
something heavily required for histograms. Specifically, the following
are converted to rb_root_cached, and users accordingly:

hist::entries_in_array
hist::entries_in
hist::entries
hist::entries_collapsed
hist_entry::hroot_in
hist_entry::hroot_out

49b8e2bece perf tools: Replace automatic const char[] variables by statics
An automatic const char[] variable gets initialized at runtime, just
like any other automatic variable. For long strings, that uses a lot of
stack and wastes time building the string; e.g. for the "No %s
allocation events..." case one has:

  444516:       48 b8 4e 6f 20 25 73 20 61 6c   movabs $0x6c61207325206f4e,%rax # "No %s al"

Make them all static so that the compiler just references objects in .rodata.

da06d56838 perf top: Fix wrong hottest instruction highlighted
The annotation line percentage is compared and inserted into the rbtree,
but the percent field of 'struct annotation_data' is an array, the
comparison result between them is the address difference.

This patch compares the right slot of percent array according to
opts->percent_type and makes things right.

The problem can be reproduced by pressing 'H' in perf top annotation view.
It should highlight the instruction line which has the highest sampling
percentage.

c2f938ba5a perf annotate: Rename struct annotation_line::samples* to data*
The name 'samples*' is little confusing because we have nested 'struct
sym_hist_entry' under annotation_line struct, which holds 'nr_samples'
as well.

Also the holding struct name is 'annotation_data' so the 'data' name
fits better.

0683d13c1a perf annotate: Get rid of annotation__scnprintf_samples_period()
We have more current function tto get the title for annotation,
which is hists__scnprintf_title. They both have same output as
far as the annotation's header line goes.

They differ in counting of the nr_samples, hists__scnprintf_title
provides more accurate number based on the setup of the
symbol_conf.filter_relative variable.

Plus it also displays any uid/thread/dso/socket filters/zooms
if there are set any, which annotation__scnprintf_samples_period
does not.

fabd37b837 perf hists: Check if a hist_entry has callchains before using them
So far if we use 'perf record -g' this will make
symbol_conf.use_callchain 'true' and logic will assume that all events
have callchains enabled, but ever since we added the possibility of
setting up callchains for some events (e.g.: -e
cycles/call-graph=dwarf/) while not for others, we limit usage scenarios
by looking at that symbol_conf.use_callchain global boolean, we better
look at each event attributes.

On the road to that we need to look if a hist_entry has callchains, that
is, to go from hist_entry->hists to the evsel that contains it, to then
look at evsel->sample_type for PERF_SAMPLE_CALLCHAIN.

The next step is to add a symbol_conf.ignore_callchains global, to use
in the places where what we really want to know is if callchains should
be ignored, even if present.

Then -g will mean just to select a callchain mode to be applied to all
events not explicitely setting some other callchain mode, i.e. a default
callchain mode, and --no-call-graph will set
symbol_conf.ignore_callchains with that clear intention.

That too will at some point become a per evsel thing, that tools can set
for all or just a few of its evsels.

3183f8ca30 perf symbols: Unify symbol maps
Remove the split of symbol tables for data (MAP__VARIABLE) and for
functions (MAP__FUNCTION), its unneeded and there were various places
doing two lookups to find a symbol, so simplify this.

We still will consider only the symbols that matched the filters in
place, i.e. see the (elf_(sec,sym)|symbol_type)__filter() routines in
the patch, just so that we consider only the same symbols as before,
to reduce the possibility of regressions.

All the tests on 50-something build environments, in varios versions
of lots of distros and cross build environments were performed without
build regressions, as usual with all pull requests the other tests were
also performed: 'perf test' and 'make -C tools/perf build-test'.

Also this was done at a great granularity so that regressions can be
bisected more easily.

51f39603b5 perf annotate browser: Allow showing offsets in more than just jump targets
Jesper wanted to see offsets at callq sites when doing some performance
investigation related to retpolines, so save him some time by providing
a 'O' hotkey to allow showing offsets from function start at call
instructions or in all instructions, just go on pressing 'O' till the
offsets you need appear.

94e87a8bd5 perf hists browser: Remove leftover from row returned from refresh
The per-browser screen refresh routine (ui_browser->refresh()) should
return the first row that should be cleaned after the rows just printed,
in case not all rows available on the screen gets filled.

When moving the extra title lines logic from the hists browser to the
generic ui_browser class, one piece of that logic remained in the hists
browser and then when going back from the annotate browser to the hists
browser in a case where fewer lines were displayed in the hists browser,
for instance when filtering the entries per substring, one line of the
annotate browser would remain on the screen, fix that.

Example of the screen artifact:

================================================================================
Samples: 73K of event 'cycles:ppp', 4000 Hz, Event count (approx.): 45172901394
Overhead  Shared O  Symbol
   0.30%  [kernel]  [k] __indirect_thunk_start
   0.09%  [kernel]  [k] __x86_indirect_thunk_r10
       │      lfence
================================================================================

Here from 'perf top' the view was zoomed with '/thunk' to functions
having that substring, then the first was annotated and from the
annotate browser ESC was pressed, then the first lines were overwritten,
but the 'lfence' line remained due to the off by one bug fixed in this
cset.

e726c8511c perf annotate browser: Fixup vertical line separating metrics from instructions
Now that we can have extra title lines we should use ui_browser->rows
and not ->height when drawing lines, as it will use ui_browser__gotorc()
and that will take the extra title lines into account, which was causing
an off by one at the end of the vertical line drawn by
__ui_browser__vline(), fix it.

The visual effect was that the last line, with status messages, was
being overwritten by the vertical line, looking like:

ef9ff6017e perf ui browser: Move the extra title lines from the hists browser
This will be useful for the annotate browser as well, that wants to have
extra title lines, i.e. the current ui_browser unconditionally reserves
the first line for a browser title and the last one for status messages.

But some browsers, like the buckets one (hists browser) needs extra
lines to show headers, allowing it to be shown or not, press 'H' in
'perf top' or 'perf report' to see this feature.

So move that logic to the core ui_browser used by the hists_browser
('perf top' and 'perf report' main interface) so that it can be used by
the annotate browser too.

The previous patch made this function useful to non-TUI parts of the

the patch showed more clearly the process.

Now just move it outside the TUI parts so that we can finally use it,
even when the TUI code doesn't get built/linked.

tools or UIs.

e4cc91b802 perf annotate: Support jumping from one function to another
For instance:

  entry_SYSCALL_64  /lib/modules/4.16.0-rc5-00086-gdf09348f78dc/build/vmlinux
    5.50 │     → callq  do_syscall_64

         │     → jne    swapgs_restore_regs_and_return_to_usermode

    0.65 │     → jne    swapgs_restore_regs_and_return_to_usermode

It'll behave just like a "call" instruction, i.e. press enter or right
arrow over one such line and the browser will navigate to the annotated
disassembly of that function, which when exited, via left arrow or esc,
will come back to the calling function.

Now to support jump to an offset on a different function...

2eff061162 perf annotate: Add "_local" to jump/offset validation routines
Because they all really check if we can access data structures/visual
constructs where a "jump" instruction targets code in the same function,
i.e. things like:

  __pthread_mutex_lock  /usr/lib64/libpthread-2.26.so
  1.95 │       mov    __pthread_force_elision,%ecx
       │    ┌──test   %ecx,%ecx
  0.07 │    ├──je     60
       │    │  test   $0x300,%esi
       │    │↓ jne    60
       │    │  or     $0x100,%esi
       │    │  mov    %esi,0x10(%rdi)
       │ 42:│  mov    %esi,%edx
       │    │  lea    0x16(%r8),%rsi
       │    │  mov    %r8,%rdi
       │    │  and    $0x80,%edx
       │    │  add    $0x8,%rsp
       │    │→ jmpq   __lll_lock_elision
       │    │  nop
  0.29 │ 60:└─→and    $0x80,%esi
  0.07 │       mov    $0x1,%edi
  0.29 │       xor    %eax,%eax
  2.53 │       lock   cmpxchg %edi,(%r8)

And not things like that "jmpq __lll_lock_elision", that instead should behave
like a "call" instruction and "jump" to the disassembly of "___lll_lock_elision".

d9bd766584 perf annotate browser: Add 'P' hotkey to dump annotation to file
Just like we have in the histograms browser used as the main screen for

Here is one example of pressing 'A' on 'perf top' to live annotate a
kernel function and then press 'P' to dump that annotation, the
resulting file:
