Add a perf script which shows packets processing and processed
time. It helps us to investigate networking or network devices.
If you want to use it, install perf and record perf.data like
following.
If you set script, perf gathers records until it ends.
If not, you must Ctrl-C to stop recording.
And if you want a report from record,
If you use some options, you can limit the output.
Option is below.
tx: show only tx packets processing
rx: show only rx packets processing
dev=: show processing on this device
debug: work with debug mode. It shows buffer status.
For example, if you want to show received packets processing
associated with eth4,
106133.171439sec cpu=0
irq_entry(+0.000msec irq=24:eth4)
|
softirq_entry(+0.006msec)
|
|---netif_receive_skb(+0.010msec skb=f2d15900 len=100)
| |
| skb_copy_datagram_iovec(+0.039msec 10291::10291)
|
napi_poll_exit(+0.022msec eth4)
This perf script helps us to analyze the processing time of a
transmit/receive sequence.

With scheduler traces covering more than two cpus, rectangles
of the CPUs 3 and more are not visibles.
This makes the vertical navigation scrollable so that all of the
CPUs rectangles are available.
We also want to be able to zoom vertically, so that we can fit at
best the screen with CPU rectangles, but that's for later.

Without vertical zoom, it is not possible to see all CPUs in a trace
taken on a larger machine. This patch parameterizes the height and
spacing of CPUs so that you can fit more cpus into the screen.
Ideally we should dynamically size/space the CPU rectangles with some
minimum threshold. Until then, this patch is a stop-gap.

Migrate out events may happen on tasks that are not in the
runqueue, for example this is the case for tasks that are
sleeping. In this case, we don't want to log the migrate out
event in the source runqueue because the task is not eventually
in the runqueue and we have already logged its sleep event.
This fixes timeslices that spuriously propagate a sleep event
from the previous timeslice.

This brings a GUI tool that displays an overview of the load
of tasks proportion in each CPUs.
The CPUs forward progress is cut in timeslices. A new timeslice
is created for every runqueue event: a task gets pushed out or
pulled in the runqueue.
For each timeslice, every CPUs rectangle is colored with a red
power that describes the local load against the total load.
This more red is the rectangle, the higher is the given CPU load.
This load is the number of tasks running on the CPU, without
any distinction against the scheduler policy of the tasks, for
now.
Also for each timeslice, the event origin is depicted on the
CPUs that triggered it using a thin colored line on top of the
rectangle timeslice.
These events are:
* sleep: a task went to sleep and has then been pulled out the
runqueue. The origin color in the thin line is dark blue.
* wake up: a task woke up and has then been pushed in the
runqueue. The origin color is yellow.
* wake up new: a new task woke up and has then been pushed in the
runqueue. The origin color is green.
* migrate in: a task migrated in the runqueue due to a load
balancing operation. The origin color is violet.
* migrate out: reverse of the previous one. Migrate in events
usually have paired migrate out events in another runqueue.
The origin color is light blue.
Clicking on a timeslice provides the runqueue event details
and the runqueue state.
The CPU rectangles can be navigated using the usual arrow
controls. Horizontal zooming in/out is possible with the
"+" and "-" buttons.

trace_unhandled() callback does not allow to access event fields, this patch
resolves the problem.
It can also been used as a more pythonic and flexible way for script writters
to demux event types
This will for example greatly simplify pytimechart event demux.

It should be possible to run any perf trace script in 'live
mode'. This requires being able to pass in e.g. '-i -' or other
args, which the current shell scripts aren't equipped to handle.
In a few cases, there are required or optional args that also
need special handling. This patch makes changes the current set
of shell scripts as necessary.

A couple of scripts, one in Python and the other in Perl, that
demonstrate 'live mode' tracing. For each, the output of the
perf event stream is fed continuously to the script, which
continuously aggregates the data and reports the current results
every 3 seconds, or at the optionally specified interval. After
the current results are displayed, the aggregations are cleared
and the cycle begins anew.
To run the scripts, simply pipe the output of the 'perf trace
record' step as input to the corresponding 'perf trace report'
step, using '-' as the filename to -o and -i:
$ perf trace record sctop -o - | perf trace report sctop -i -
Also adds clear_term() utility functions to the Util.pm and
Util.py utility modules, for use by any script to clear the
screen.

Adds a set of scripts that aggregate system call totals and system
call errors. Most are Python scripts that also test basic
functionality of the new Python engine, but there's also one Perl
script added for comparison and for reference in some new
