perf scripts: Fallback to syscalls:* when raw_syscalls:* is not available

2014-06-25T15:26:56+00:00

Older kernels (e.g., RHEL6) do system call tracing via the syscalls:sys_{enter,exit} tracepoints rather than using raw_syscalls:*. Update perf python and perl scripts to fallback to syscalls:* when raw_syscalls:* isn't available. Signed-off-by: Daniel Bristot de Oliveira Cc: Ingo Molnar Cc: Luis Claudio R.

perf script: Remove workqueue-stats script

2013-01-24T19:40:53+00:00

The tracepoints used by the workqueue-stats script no longer exist so trying to run the script results in: # perf script record workqueue-stats invalid or unsupported event: 'workqueue:workqueue_creation' Run 'perf list' for a list of valid events So remove the script until it can be reworked using the new workqueue tracepoints.

The scripts have calls to 'perf trace' that need to be converted to 'perf script', do it. This problem was introduced in 133dc4c.

perf trace scripting: remove system-wide param from shell scripts

2010-11-10T14:08:20+00:00

Including -a unconditionally when recording doesn't allow for the option of running scripts without it. Future patches will add add it back if needed at run-time. Signed-off-by: Tom Zanussi Acked-by: Arnaldo Carvalho de Melo

perf trace: Use $PERF_EXEC_PATH in canned report scripts

2010-10-23T17:31:20+00:00

Set $PERF_EXEC_PATH before starting the record and report scripts, and make them use it where necessary. Cc: Ingo Molnar Cc: Paul Mackerras Cc: Peter Zijlstra LKML-Reference: <1286723403.2955.205.camel@localhost> Signed-off-by: Ben Hutchings Signed-off-by: Arnaldo Carvalho de Melo

perf/trace/scripting: failed-syscalls script cleanup

2010-05-10T22:50:54+00:00

A couple small fixes for the failed syscalls script: - The script description says it can be restricted to a specific comm, make it so. - silence the match output in the shell script Cc: Frédéric Weisbecker Cc: Ingo Molnar LKML-Reference: <1273466820-9330-2-git-send-email-tzanussi@gmail.com> Signed-off-by: Tom Zanussi Signed-off-by: Arnaldo Carvalho de Melo

perf: Remove leftover useless options to record trace events from scripts

2010-04-30T17:55:00+00:00

-f, -c 1, -R are now useless for trace events recording, moreover -M is useless and event hurts. Remove them from the documentation examples and from record scripts.

perf trace/scripting: Enable scripting shell scripts for live mode

2010-04-14T09:56:08+00:00

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.

perf trace/scripting: Add rwtop and sctop scripts

2010-04-14T09:56:08+00:00

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.

perf/scripts: Add syscall tracing scripts

2010-02-25T03:07:48+00:00

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 Documentation contained in a later patch.
