0f80bfbf49 perf scripts python: intel-pt-events.py: Fix printing of switch events
The intel-pt-events.py script displays only the last of consecutive switch
statements but that may not be the last switch event for the CPU. Fix by
keeping a dictionary of last context switch keyed by CPU, and make it
possible to see all switch events by adding option --all-switch-events.

f56299a9c9 perf scripts python: exported-sql-viewer.py: Fix warning display
Deprecation warnings are useful only for the developer, not an end user.
Display warnings only when requested using the python -W option. This
stops the display of warnings like:

 tools/perf/scripts/python/exported-sql-viewer.py:5102: DeprecationWarning:
         an integer is required (got type PySide2.QtCore.Qt.AlignmentFlag).
         Implicit conversion to integers using __int__ is deprecated, and
         may be removed in a future version of Python.
    err = app.exec_()

Since the warning can be fixed only in PySide2, we must wait for it to
be finally fixed there.

fd931b2e23 perf scripts python: exported-sql-viewer.py: Fix Array TypeError
The 'Array' class is present in more than one python standard library.
In some versions of Python 3, the following error occurs:

Traceback (most recent call last):

    reports_menu.addAction(CreateAction(label, "Create a new window displaying branch events", lambda a=None,x=dbid: self.NewBranchView(x), self))

    self.model = LookupCreateModel(model_name, lambda: BranchModel(glb, event_id, report_vars.where_clause))
  File "tools/perf/scripts/python/exported-sql-viewer.py", line 343, in LookupCreateModel
    model = create_fn()
  File "tools/perf/scripts/python/exported-sql-viewer.py", line 3208, in <lambda>

  File "tools/perf/scripts/python/exported-sql-viewer.py", line 2658, in __init__
    self.buffer = Array(c_char, self.buffer_size, lock=False)
TypeError: abstract class

This apparently happens because Python can be inconsistent about which
class of the name 'Array' gets imported. Fix by importing explicitly by
name so that only the desired 'Array' gets imported.

2a684fcb60 perf script: Autopep8 futex-contention
10 years leaves its mark! Python has evolved and so has its style guide.
Even with vim it is getting hard to follow the no longer valid
guidelines (spaces vs. tabs).

Autopep8 this code to modernize it!

f18d5cf86c perf scripts python: exported-sql-viewer.py: Fix time chart call tree
Using Python version 3.8.2 and PySide2 version 5.14.0, time chart call tree
would not expand the tree to the result. Fix by using setExpanded().

Example:

  $ perf record -e intel_pt//u uname
  Linux
  [ perf record: Woken up 1 times to write data ]
  [ perf record: Captured and wrote 0.034 MB perf.data ]
  $ perf script --itrace=bep -s ~/libexec/perf-core/scripts/python/export-to-sqlite.py perf.data.db branches calls
