perf script: Add callchain to generic and tracepoint events

2014-07-16T20:57:33Z

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

2010-12-25T13:29:02Z

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

2010-08-01T23:32:00Z

Librarize the task state and event headers helpers as they can be generally useful. Signed-off-by: Frederic Weisbecker Cc: Ingo Molnar Cc: Peter Zijlstra Cc: Arnaldo Carvalho de Melo Cc: Paul Mackerras Cc: Nikhil Rao Cc: Tom Zanussi

perf, sched migration: Librarize the GUI class

2010-08-01T23:31:59Z

Export the GUI facility in the common library path. It is going to be useful for other scheduler views. Signed-off-by: Frederic Weisbecker Cc: Ingo Molnar Cc: Peter Zijlstra Cc: Arnaldo Carvalho de Melo Cc: Paul Mackerras Cc: Nikhil Rao Cc: Tom Zanussi

perf, sched migration: Make the GUI class client agnostic

2010-08-01T23:31:58Z

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

2010-08-01T23:31:57Z

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

2010-08-01T23:31:56Z

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.

perf, sched migration: Fix key bindings

2010-08-01T23:31:55Z

EVT_KEY_DOWN and EVT_LEFT_DOWN events are not bound to the RootFrame event handler. As a result, zoom/scroll via keyboard events do not work. This patch adds the missing bindings.

perf, sched migration: Ignore unhandled task states

2010-08-01T23:31:54Z

Stop printing an error message when we don't have the letter for a given task state. All we need to know is if the task is in the TASK_RUNNING state. Signed-off-by: Frederic Weisbecker Cc: Ingo Molnar Cc: Peter Zijlstra Cc: Arnaldo Carvalho de Melo Cc: Paul Mackerras Cc: Nikhil Rao Cc: Tom Zanussi

perf, sched migration: Handle ignored migrate out events

2010-08-01T23:31:53Z

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.
