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.

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: NFeng Tang <feng.tang@intel.com> Cc: Andi Kleen <andi@firstfloor.org> Cc: David Ahern <dsahern@gmail.com> Cc: Ingo Molnar <mingo@elte.hu> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Robert Richter <robert.richter@amd.com> Cc: Stephane Eranian <eranian@google.com> Link: http://lkml.kernel.org/r/1344419875-21665-6-git-send-email-feng.tang@intel.comSigned-off-by: NArnaldo Carvalho de Melo <acme@redhat.com>

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.

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.

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.

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.

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.
