b2b9169960 perf scripts intel-pt-events.py: Fix IPC output for Python 2 
[ Upstream commit 1f64cfdebfe0494264271e8d7a3a47faf5f58ec7 ]

Integers are not converted to floats during division in Python 2 which
results in incorrect IPC values. Fix by switching to new division
behavior.

b226521923 perf scripts python: Let script to be python2 compliant 
The mainline kernel can be used for relative old distros, e.g. RHEL 7.
The distro doesn't upgrade from python2 to python3, this causes the
building error that the python script is not python2 compliant.

To fix the building failure, this patch changes from the python f-string
format to traditional string format.

12fdd6c009 perf scripts python: Support Arm CoreSight trace data disassembly 
This commit adds python script to parse CoreSight tracing event and
print out source line and disassembly, it generates readable program
execution flow for easier humans inspecting.

The script receives CoreSight tracing packet with below format:

                +------------+------------+------------+
  packet(n):    |    addr    |    ip      |    cpu     |
                +------------+------------+------------+
  packet(n+1):  |    addr    |    ip      |    cpu     |
                +------------+------------+------------+

packet::addr presents the start address of the coming branch sample, and
packet::ip is the last address of the branch smple.  Therefore, a code
section between branches starts from packet(n)::addr and it stops at
packet(n+1)::ip.  As results we combines the two continuous packets to
generate the address range for instructions:

  [ sample(n)::addr .. sample(n+1)::ip ]

The script supports both objdump or llvm-objdump for disassembly with
specifying option '-d'.  If doesn't specify option '-d', the script
simply outputs source lines and symbols.

Below shows usages with llvm-objdump or objdump to output disassembly.

75659c6fb5 perf scripts python: intel-pt-events.py: Print ptwrite value as a string if it is ASCII 
It can be convenient to put a string value into a ptwrite payload as
a quick and easy way to identify what is being printed.

To make that useful, if the Intel ptwrite payload value contains only
printable ASCII characters padded with NULLs, then print it also as a
string.

Using the example program from the "Emulated PTWRITE" section of
tools/perf/Documentation/perf-intel-pt.txt:

 $ echo -n "Hello" | od -t x8
 0000000 0000006f6c6c6548

 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):
  File "tools/perf/scripts/python/exported-sql-viewer.py", line 4702, in <lambda>
    reports_menu.addAction(CreateAction(label, "Create a new window displaying branch events", lambda a=None,x=dbid: self.NewBranchView(x), self))
  File "tools/perf/scripts/python/exported-sql-viewer.py", line 4727, in NewBranchView
    BranchWindow(self.glb, event_id, ReportVars(), self)
  File "tools/perf/scripts/python/exported-sql-viewer.py", line 3208, in __init__
    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>
    self.model = LookupCreateModel(model_name, lambda: BranchModel(glb, event_id, report_vars.where_clause))
  File "tools/perf/scripts/python/exported-sql-viewer.py", line 3124, in __init__
    self.fetcher = SQLFetcher(glb, sql, prep, self.AddSample)
  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.
