In d10ec006dc ("perf hists browser: Allow passing an initial hotkey")
the hist_entry__title() call was cut'n'pasted to a function where the
'title' variable is a pointer, not an array, so the sizeof(title)
continues syntactically valid but ends up reducing the real size of the
buffer where to format the first line in the screen to 8 bytes, which
makes the formatting at the title at each refresh to produce just the
string "Samples ", duh, fix it by passing the size of the buffer.

When performing "perf report --group", it shows the event group information
together. In previous patch, we have supported a new option "--group-sort-idx"
to sort the output by the event at the index n in event group.
It would be nice if we can use a hotkey in browser to select a event
to sort.
For example,
# perf report --group

Sometimes we may need to reload the browser to update the output since
some options are changed.
This patch creates a new key K_RELOAD. Once the __cmd_report() returns
K_RELOAD, it would repeat the whole process, such as, read samples from
data file, sort the data and display in the browser.
v5:
---
1. Fix the 'make NO_SLANG=1' error. Define K_RELOAD in util/hist.h.
2. Skip setup_sorting() in repeat path if last key is K_RELOAD.

Now the output is sorted by the fourth event in group.
v7:
---
Rebase to latest perf/core, no other change.
v4:
---
1. Update Documentation/perf-report.txt to mention
'--group-sort-idx' support multiple groups with different
amount of events and it should be used on grouped events.
2. Update __hpp__group_sort_idx(), just return when the
idx is out of limit.
3. Return failure on symbol_conf.group_sort_idx && !session->evlist->nr_groups.
So now we don't need to use together with --group.
v3:
---
Refine the code in __hpp__group_sort_idx().
Before:
for (i = 1; i < nr_members; i++) {
if (i == idx) {
ret = field_cmp(fields_a[i], fields_b[i]);

goto out;
}
}
After:
if (idx >= 1 && idx < nr_members) {
ret = field_cmp(fields_a[idx], fields_b[idx]);
if (ret)
goto out;

For perf report on stripped binaries it is currently impossible to do
annotation. The annotation state is all tied to symbols, but there are
either no symbols, or symbols are not covering all the code.
We should support the annotation functionality even without symbols.
This patch fakes a symbol and the symbol name is the string of address.
After that, we just follow current annotation working flow.
For example,
1. perf report
Overhead Command Shared Object Symbol
20.67% div libc-2.27.so [.] __random_r
17.29% div libc-2.27.so [.] __random
10.59% div div [.] 0x0000000000000628
9.25% div div [.] 0x0000000000000612
6.11% div div [.] 0x0000000000000645
2. Select the line of "10.59% div div [.] 0x0000000000000628" and ENTER.
Annotate 0x0000000000000628
Zoom into div thread
Zoom into div DSO (use the 'k' hotkey to zoom directly into the kernel)
Browse map details
Run scripts for samples of symbol [0x0000000000000628]
Run scripts for all samples
Switch to another data file in PWD
Exit
3. Select the "Annotate 0x0000000000000628" and ENTER.
Percent│
│
│
│ Disassembly of section .text:
│
│ 0000000000000628 <.text+0x68>:
│ divsd %xmm4,%xmm0
│ divsd %xmm3,%xmm1
│ movsd (%rsp),%xmm2
│ addsd %xmm1,%xmm0
│ addsd %xmm2,%xmm0
│ movsd %xmm0,(%rsp)
Now we can see the dump of object starting from 0x628.
v5:
---
Remove the hotkey 'a' implementation from this patch. It
will be moved to a separate patch.
v4:
---
1. Support the hotkey 'a'. When we press 'a' on address,
now it supports the annotation.
2. Change the patch title from
"Support interactive annotation of code without symbols" to
"perf report: Support interactive annotation of code without symbols"
v3:
---
Keep just the ANNOTATION_DUMMY_LEN, and remove the
opts->annotate_dummy_len since it's the "maybe in future
we will provide" feature.
v2:
---
Fix a crash issue when annotating an address in "unknown" object.
The steps to reproduce this issue:
perf record -e cycles:u ls
perf report
75.29% ls ld-2.27.so [.] do_lookup_x
23.64% ls ld-2.27.so [.] __GI___tunables_init
1.04% ls [unknown] [k] 0xffffffff85c01210
0.03% ls ld-2.27.so [.] _start
When annotating 0xffffffff85c01210, the crash happens.
v2 adds checking for ms->map in add_annotate_opt(). If the object is
"unknown", ms->map is NULL.
Committer notes:
Renamed new_annotate_sym() to symbol__new_unresolved().
Use PRIx64 to fix this issue in some 32-bit arches:
ui/browsers/hists.c: In function 'symbol__new_unresolved':
ui/browsers/hists.c:2474:38: error: format '%lx' expects argument of type 'long unsigned int', but argument 5 has type 'u64' {aka 'long long unsigned int'} [-Werror=format=]

perf annotate --show-nr-samples does not really show number of samples.
The reason is we have two separate variables for the same purpose.
One is in symbol_conf.show_nr_samples and another is
annotation_options.show_nr_samples.
We save command line option in symbol_conf.show_nr_samples but uses
annotation_option.show_nr_samples while rendering tui/stdio2 browser.
Though, we copy symbol_conf.show_nr_samples to
annotation__default_options.show_nr_samples but that is not really
effective as we don't use annotation__default_options once we copy
default options to dynamic variable annotate.opts in cmd_annotate().
Instead of all these complication, keep only one variable and use it all
over. symbol_conf.show_nr_samples is used by perf report/top as well. So
let's kill annotation_options.show_nr_samples.
On a side note, I've kept annotation_options.show_nr_samples definition
because it's still used by perf-config code. Follow up patch to fix
perf-config for annotate will remove annotation_options.show_nr_samples.

The 'e' and 'c' hotkeys were present for a long time, but not documented
in the help window, change 'e' to be a toggle so that it gets consistent
with other toggles like '+' and document it in the help window.
Keep 'c' as is for people used to it but don't document, as it is easier
to just use 'e' to show/hide all the callchains for a top level
histogram entry.

This can happen in the --children mode, i.e. the default mode when
callchains are present, where one of the main entries may be a callchain
entry with no samples.
So far we were not providing any information about why an annotation
couldn't be provided even offering the Annotation option in the popup
menu.
Work is needed to allow for no-samples "annotation', i.e. to show the
disassembly anyway and allow for navigation, etc.

When the users presses ENTER in the main 'perf report/top' screen a
popup menu is presented, in it some hotkeys are suggested as
alternatives to using the menu, or for additional features.
At that point the user may try those hotkeys, so allow for that by
recording the key used and exiting, the caller then can check for that
possibility and process the hotkey.
I.e. try pressing ENTER, and then 'k' to exit and zoom into the kernel

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.

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).

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.

Now that sort.h isn't included by any other header, we can check where
it is really needed, i.e. we can remove it and be sure that it isn't
being obtained indirectly.

So that we can reduce the header dependency tree further, in the process
noticed that lots of places were getting even things like build-id
routines and 'struct perf_tool' definition indirectly, so fix all those
too.
