45694aa770 perf tools: Rename perf_event_ops to perf_tool
To better reflect that it became the base class for all tools, that must
be in each tool struct and where common stuff will be put.

743eb86865 perf tools: Resolve machine earlier and pass it to perf_event_ops
Reducing the exposure of perf_session further, so that we can use the
classes in cases where no perf.data file is created.

d20deb64e0 perf tools: Pass tool context in the the perf_event_ops functions
So that we don't need to have that many globals.

Next steps will remove the 'session' pointer, that in most cases is
not needed.

Then we can rename perf_event_ops to 'perf_tool' that better describes
this class hierarchy.

Paving the way to remove these globals when we change the perf_event_ops

e3f4260962 perf tools: Use evsel->attr.sample_type instead of session->sample_type
Eventually session->sample_type will go away as we want to support
multiple sample types per session, so use it from the evsel which is a

ebf294bf4f perf tools: Simplify debugfs mountpoint handling code
We don't need to have two PATH_MAX char sized arrays holding it, just
one in util/debugfs.c will do.

Also rename debugfs_path to tracing_events_path, as it is not the path
to debugfs, that is debugfs_mountpoint. Both are now accessible.

This will allow accessing this code in the perf python binding without
having to drag in perf.c and util/parse-events.c.

The defaults for these variables are the canonical "/sys/kernel/debug"
and "/sys/kernel/debug/tracing/events/", removing the need for simple
tools to call debugfs_mount(NULL).

0e7a22de25 ktest: When creating new config, allow the use of ${THIS_DIR}
Typing in a full path when you know that the path exists within
the directory your are running is tedious and unnecessary.

Allow the user to use ${PWD} if they want a dynamic path name
which will be the path that ktest.pl is executed from
or use ${THIS_DIR} which is a variable assigned `pwd` and
the the variable will exist within the config, allowing the user
to change it and affect all other paths using this variable as well

questions to create a simple ktest config file.

A few of the questions should have a default value set, that if anything

be in that value.

These new values are:

  SSH_USER, BUILD_TARGET and TARGET_IMAGE

ImportError: /home/acme/git/build/perf/python/perf.so: undefined symbol: hists__init

Fix it by moving the hists__init function to its only caller, evsel.c.

This way we avoid dragging in other parts of tools/perf/util/ to the
perf python binding.

49908a1b25 perf: Fix parsing of __print_flags() in TP_printk()
A update is made to the sched:sched_switch event that adds some
logic to the first parameter of the __print_flags() that shows the
state of tasks. This change cause perf to fail parsing the flags.

A simple fix is needed to have the parser be able to process ops
within the argument.

f9e3d4b1a9 perf top: Fix live annotation in the --stdio interface
In the old --stdio interface the annotation is done just after one
selects a symbol, while in --tui, now the default when the required libs
are installed, we annotate all symbols with samples so that when
annotation is asked we see what happened recently on that symbol.

To achieve that the --stdio variant checks if the hist_entry being
processed is the one selected by the user via the 's' hotkey. What
happens now that we share the hist_entry abstractions with 'perf report'
is that for minimizing locking contention multiple rb_trees are used,
one for collecting the samples and other to browse/show them after
resorting it by number of samples and decay them, which is done
periodically.

So the simple test in record_precise_ip doesn't work as we move
hist_entries between those rb_trees. To fix it just check that the
underlying struct symbol associated with those hist_entries is the same.

104268a335 perf top tui: Don't recalc column widths considering just the first page
It makes sense for the stdio where we can't navigate to the other pages.

On the TUI it breaks as soon as we navigate to other pages that have,
DSOs with longer names than the ones on the first page.

7b27509fc6 perf hists browser: Warn about lost events
Just like the old perf top --tui and the --stdio version.

But because we have the initial menu to choose which event to show in a
session with multiple events we can see how many chunks were lost in
each of the event types, clarifying which events are being affected the
most.

815e2bd7d6 ktest: Evaluate variables entered on the command line
When ktest.pl is called without any arguments, or if the config
file does not exist, ktest.pl will ask the user for some information.
Some of these questions are code paths. Allowing the user to type
${PWD} for the current directory greatly simplifies these entries.

Add variable processing to the entered values.

7928631a66 perf hists: Fix recalculation of total_period when sorting entries
We were doing parts of it in hists__collapse_resort and parts of it in
hists__output_resort, leading to a bogus total_period.

Fix it by doing just the filtering operation when collapsing because
there we know that the Zoom operations adds filters just  what is in
hists->entries, not to the new batch of entries being collapsed.

And move all the nr_entries + total_period recalculation to
hists__output_resort since we will traverse all entries anyway there.

Problem introduced when developing threaded addition of new batches
of hist_entries, i.e. post v3.1.

a9072bc0b0 perf header: Fix build on old systems

CC /home/acme/git/build/perf/util/header.o
cc1: warnings being treated as errors
util/header.c: In function ‘write_cpudesc’:
util/header.c:281: warning: implicit declaration of function ‘getline’

make: *** [/home/acme/git/build/perf/util/header.o] Error 1
make: Leaving directory `/home/acme/git/linux/tools/perf'

This happens due to header ordering, in perf util.h sets _GNU_SOURCE, so
it must come first.
