perf: net_dropmonitor: Remove progress indicator

2013-05-22T22:10:11Z

We can read /proc/kallsyms in a fraction of a second, so why waste a further fraction of a second showing progress? Signed-off-by: Ben Hutchings Signed-off-by: David S. Miller

perf: net_dropmonitor: Use bisection in symbol lookup

perf: net_dropmonitor: Do not assume ordering of dictionaries

2013-05-22T22:10:10Z

The sort order of dictionaries in Python is undocumented. Use tuples instead, which are documented to be lexically ordered. Signed-off-by: Ben Hutchings Signed-off-by: David S. Miller

perf: net_dropmonitor: Fix symbol-relative addresses

2013-05-22T22:10:10Z

The comparison between traced and symbol addresses is backwards: if the traced address doesn't exactly match a symbol (which we don't expect it to), we'll show the next symbol and the offset to it, whereas we should show the previous symbol and the offset from it.

perf: net_dropmonitor: Fix trace parameter order

2013-05-22T22:10:10Z

This works much better if we don't treat protocol numbers as addresses. Cc: stable@vger.kernel.org Signed-off-by: Ben Hutchings Signed-off-by: David S. Miller

perf script python: Correct handler check and spelling errors

2012-08-09T16:26:19Z

Correct the checking for handler returned by PyDict_GetItemString(), also fix some spelling error and remove some data code in event_analyzing_sample.py, as suggested by Namhyung Kim. v2: restore back the wrongly removed trace_unhandled() func Signed-off-by: Feng Tang Acked-by: Namhyung Kim Cc: Andi Kleen Cc: David Ahern Cc: Ingo Molnar Cc: Namhyung Kim Cc: Peter Zijlstra Cc: Robert Richter Cc: Stephane Eranian Link: http://lkml.kernel.org/r/20120809134613.067104c4@feng-i7 Signed-off-by: Arnaldo Carvalho de Melo

perf scripts python: Add event_analyzing_sample.py as a sample for general event handling

2012-08-08T15:55:38Z

Currently only trace point events are supported in perf/python script, the first 3 patches of this serie add the support for all types of events. This script is just a simple sample to show how to gather the basic information of the events and analyze them. This script will create one object for each event sample and insert them into a table in a database, then leverage the simple SQL commands to sort/group them. User can modify or write their brand new functions according to their specific requirment. Here is the sample of how to use the script: $ perf record -a tree $ perf script -s process_event.py There is 100 records in gen_events table Statistics about the general events grouped by thread/symbol/dso: comm number histgram ========================================== swapper 56 ###### tree 20 ##### perf 10 #### sshd 8 #### kworker/7:2 4 ### ksoftirqd/7 1 # plugin-containe 1 # symbol number histgram ========================================================== native_write_msr_safe 40 ###### __lock_acquire 8 #### ftrace_graph_caller 4 ### prepare_ftrace_return 4 ### intel_idle 3 ## native_sched_clock 3 ## Unknown_symbol 2 ## do_softirq 2 ## lock_release 2 ## lock_release_holdtime 2 ## trace_graph_entry 2 ## _IO_putc 1 # __d_lookup_rcu 1 # __do_fault 1 # __schedule 1 # _raw_spin_lock 1 # delay_tsc 1 # generic_exec_single 1 # generic_fillattr 1 # dso number histgram ================================================================== [kernel.kallsyms] 95 ####### /lib/libc-2.12.1.so 5 ### Signed-off-by: Feng Tang Cc: Andi Kleen Cc: David Ahern Cc: Ingo Molnar Cc: Peter Zijlstra Cc: Robert Richter Cc: Stephane Eranian Link: http://lkml.kernel.org/r/1344419875-21665-6-git-send-email-feng.tang@intel.com Signed-off-by: Arnaldo Carvalho de Melo

perf scripts python: Add a python library EventClass.py

2012-08-08T15:53:08Z

This library defines several class types for perf events which could help to better analyze the event samples. Currently there are just a few classes, PerfEvent is the base class for all perf events, PebsEvent is a HW base Intel x86 PEBS event, and user could add more SW/HW event classes based on requriements.

perf script: Add drop monitor script

2011-09-29T19:41:37Z

A while back I created the dropmonitor protocol, which allowed users to get reports of dropped frames communicated to them via a netlink socket. While useful, several people have now asked that I integrate the ability to do drop monitoring with perf, so they don't have to run additional tools. This patch adds a drop monitor script to the perf suite, and provides the same output that the netlink socket does.
