These patches change the event tracer to provide id files:
[root@opteron ~]# for i in /debug/tracing/events/irq/*/id; do echo `cat $i` - $i; done
28 - /debug/tracing/events/irq/irq_handler_entry/id
29 - /debug/tracing/events/irq/irq_handler_exit/id
27 - /debug/tracing/events/irq/softirq_entry/id
26 - /debug/tracing/events/irq/softirq_exit/id
These can then be used in profiling as:
[root@opteron linux-2.6]# ~/perfstat -e 2:28 make O=native-build/ -j4 lib
...
Performance counter stats for 'make':
18280.657602 task clock ticks (msecs)
465 tp: 28 (events)
Wall-clock time elapsed: 11265.199196 msecs
Showing that we had 465 irq_handler_entry events during that workload.

[-- Type: text/plain, Size: 1435 bytes --]
When doing the generic context switch event I ran into some early boot
hangs, which were caused by inf func recursion (event, fault, event, fault).
I eventually tracked it down to event_list not being initialized at the
time of the first event. Fix this.

Previously only TRACE_EVENT events got ids, because only they generated
raw output which needs to be demuxed from the trace.
In order to provide a unique ID for each event, register everybody, regardless.

I found another counter free path, create a free_counter() call to accomodate
generic tear-down.
Fixes an RCU bug.

Enable usage of tracepoints as perf counter events.
tracepoint event ids can be found in /debug/tracing/event/*/*/id
and (for now) are represented as -65536+id in the type field.

[-- Attachment #1: perf_counter-input-abi.patch --]
[-- Type: text/plain, Size: 13334 bytes --]
The hardware/software classification in hw_event->type became a little strained
due to the addition of tracepoint tracing.
Instead split up the field and provide a type field to explicitly specify the
counter type, while using the event_id field to specify which event to use.
Raw counters still work as before, only the raw config now goes into raw_event.

Having 3 slightly different copies of the same code around does nobody any
good. First step in revamping the output format.

Let's have a better patch description (my fault for not providing a
decent one in the first place):
perf_counter: powerpc: clean up perf_counter_interrupt
From: Paul Mackerras <paulus@samba.org>
This updates the powerpc perf_counter_interrupt following on from the
"perf_counter: unify irq output code" patch. Since we now use the
generic perf_counter_output code, which sets the perf_counter_pending
flag directly, we no longer need the need_wakeup variable. This
removes need_wakeup and makes perf_counter_interrupt use
get_perf_counter_pending() instead.

nice! I suspect perfstat could use "-e irq_handler_entry" type of
symbolic input as well.
I've started picking up the patches and started testing them.

ftrace: ensure every event gets an id
Impact: widen user-space visibe event IDs to all events
Previously only TRACE_EVENT events got ids, because only they
generated raw output which needs to be demuxed from the trace.
In order to provide a unique ID for each event, register everybody,
regardless.

perf_counter: fix uninitialized usage of event_list
Impact: fix boot crash
When doing the generic context switch event I ran into some early
boot hangs, which were caused by inf func recursion (event, fault,
event, fault).
I eventually tracked it down to event_list not being initialized
at the time of the first event. Fix this.

perf_counter: hook up the tracepoint events
Impact: new perfcounters feature
Enable usage of tracepoints as perf counter events.
tracepoint event ids can be found in /debug/tracing/event/*/*/id
and (for now) are represented as -65536+id in the type field.

perf_counter: revamp syscall input ABI
Impact: modify ABI
The hardware/software classification in hw_event->type became a little
strained due to the addition of tracepoint tracing.
Instead split up the field and provide a type field to explicitly specify
the counter type, while using the event_id field to specify which event to
use.
Raw counters still work as before, only the raw config now goes into
raw_event.

perf_counter: unify irq output code
Impact: cleanup
Having 3 slightly different copies of the same code around does nobody
any good. First step in revamping the output format.

perf_counter: powerpc: clean up perc_counter_interrupt
Impact: cleanup
This updates the powerpc perf_counter_interrupt following on from the
"perf_counter: unify irq output code" patch. Since we now use the
generic perf_counter_output code, which sets the perf_counter_pending
flag directly, we no longer need the need_wakeup variable.
This removes need_wakeup and makes perf_counter_interrupt use
get_perf_counter_pending() instead.

Adding help text would be... helpful. :)
The net result in this case was the addition of a completely-unexplained
Kconfig option late in 2.6.31-rc.
Maybe the x86 maintainers could help see that they don't push
unexplained Kconfig options upstream -- particularly ones we are asked
to enable by default?

You're right. Johannes Berg made the same complaint yesterday.
Is the below any good?

Thanks. Is this feature useful w/out debugfs?
If yes, ACK.

Not really, but I was assuming (/me goes check) that EVENT_TRACING would
mandate debugfs being there.
Hmm kernel/trace/Kconfig seems a little select heavy, but I think it'll
work out and select DEBUG_FS too.
I'll queue up the patch and push it Linus wards this cycle.
Thanks!
