perf script python: Remove mixed indentation

2019-03-06T21:09:14+00:00

Remove mixed indentation in Python scripts.  Revert to either all tabs
(most common form) or all spaces (4 or 8) depending on what was the
intent of the original commit.  This is necessary to complete Python3
support as it will flag an error if it encounters mixed indentation.

perf script python: Remove explicit shebang from Python scripts

2019-01-25T14:12:10+00:00

The scripts in scripts/python are intended to be run from 'perf script'
and the Python version used is dictated by how perf was built (PYTHON=).

Also most distros follow pep-0394 which recommends that /usr/bin/python
refer to Python2 and so may not exist on the system (if PYTHON=python3).

- Remove the explicit shebang
- Install the scripts as mode 644

perf scripts python: Add Python 3 support to sched-migration.py

2018-07-11T13:01:50+00:00

Support both Python 2 and Python 3 in the sched-migration.py script.
This should have no functional change.

perf script: Add callchain to generic and tracepoint events

2014-07-16T20:57:33+00:00

This provides valuable information for tracing performance problems.

Since this change alters the interface for the python scripts, also
adjust the script generation and the provided scripts.

perf script: Finish the rename from trace to script

2010-12-25T13:29:02+00:00

The scripts have calls to 'perf trace' that need to be converted to 'perf script', do it.

This problem was introduced in 133dc4c.

perf, sched migration: Librarize task states and event headers helpers

2010-08-01T23:32:00+00:00

Librarize the task state and event headers helpers as they can
be generally useful.

perf, sched migration: Librarize the GUI class

2010-08-01T23:31:59+00:00

Export the GUI facility in the common library path. It is
going to be useful for other scheduler views.

perf, sched migration: Make the GUI class client agnostic

2010-08-01T23:31:58+00:00

Make the perf migration GUI generic so that it can be reused for
other kinds of trace painting. No more notion of CPUs or runqueue
from the GUI class, it's now used as a library by the trace parser.

perf, sched migration: Make it vertically scrollable

2010-08-01T23:31:57+00:00

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.

perf, sched migration: Parameterize cpu height and spacing

2010-08-01T23:31:56+00:00

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.
