[PATCH 0/7] kmemtrace & tracing updates

[Eduard - Gabriel Munteanu]

Hi,

I've updated kmemtrace to make it play well with the userspace app.

The first patch has been already submitted before, but it seems it didn't
make it into -tip.

Let me know what you think and please merge what's okay. There's a GSoC idea
regarding kmemtrace and it'd benefit other students to be able to run the
kmemtrace user application.


	Cheers,
	Eduard

[PATCH 1/7] RCU: don't include unnecessary headers, allow kmemtrace w/ tracepoints

[Eduard - Gabriel Munteanu]

linux/percpu.h includes linux/slab.h, which generates circular inclusion
dependencies when trying to switch kmemtrace to use tracepoints instead
of markers. This patch allows tracing within slab headers' inline
functions.

[PATCH 2/7] tracing: provide trace_seq_reserve()

[Eduard - Gabriel Munteanu]

trace_seq_reserve() allows a caller to reserve space in a trace_seq and
write directly into it. This makes it easier to export binary data to
userspace via the tracing interface, by simply filling in a struct.

[PATCH 3/7] tracing: add missing 'extern' keywords to trace_output.h

[Eduard - Gabriel Munteanu]

Many declarations within trace_output.h are missing the 'extern' keyword
in an inconsistent manner. This adds 'extern' where it should be.

[PATCH 4/7] kmemtrace: use tracepoints

[Eduard - Gabriel Munteanu]

kmemtrace now uses tracepoints instead of markers. We no longer need to
use format specifiers to pass arguments.

[PATCH 5/7] kmemtrace: kmemtrace_alloc() must fill type_id

[Eduard - Gabriel Munteanu]

kmemtrace_alloc() was not filling type_id, which allowed garbage to make
it into tracing data.

[PATCH 6/7] kmemtrace: restore original tracing data binary format, improve ABI

[Eduard - Gabriel Munteanu]

When kmemtrace was ported to ftrace, the marker strings were taken as an
indication of how the traced data was being exposed to the userspace.
However, the actual format had been binary, not text.

This restores the original binary format, while also adding an origin CPU
field (since ftrace doesn't expose the data per-CPU to userspace), and
re-adding the timestamp field. It also drops arch-independent field
sizing where it didn't make sense, so pointers won't always be 64 bits
wide like they used to.

the build error that is fixed by you here was introduced by your 
earlier 4/7 patch in this series:

   kmemtrace: use tracepoints

So i've backmerged patch 7/7 into patch 4/7. Agreed?

Thanks Eduard, nice stuff! I'll pick up your patches as they are 
nice fixes and cleanups but you might want to take a look at a few 
things that happened in tracing land in the past few weeks:

firstly, you can now fetch data in a per CPU way:

drwxr-xr-x 2 root root 0 2009-03-23 10:44 cpu8
drwxr-xr-x 2 root root 0 2009-03-23 10:44 cpu9
[root@aldebaran tracing]# ll per_cpu/cpu0/
total 0
-rw-r--r-- 1 root root 0 2009-03-23 10:44 trace
-r--r--r-- 1 root root 0 2009-03-23 10:44 trace_pipe
-r--r--r-- 1 root root 0 2009-03-23 10:44 trace_pipe_raw

This is a relatively new addition. The trace_pipe_raw file can be 
used to fetch binary data, and it has working splice() support as 
well, for zero-copy data streaming.

To get those binary records the tracepoint has to be expressed not 
in terms of DEFINE_TRACE(), but in terms of DEFINE_EVENT(). See a 
few examples in:

  include/trace/irq_event_types.h
  include/trace/sched_event_types.h

With latest -tip you can also define simple in-situ filters on each 
tracepoint, via the 'filter' file. I think this capability would be 
particularly interesting for kmemtrace, to restrict tracing to a 
given cache only, to particular sizes, etc.

This too needs DEFINE_EVENT() definition. It's more elaborate to 
express tracepoints via DEFINE_EVENT() than via 
DECLARE/DEFINE_TRACE(), but it results in faster tracing and enables 
more built-in features.

See this commit in -tip:

 |     tracing: add per-event filtering

for a short description about how these filters work.

Thanks,

	Ingo

kmemtrace: restore original tracing data binary format, improve ABI

When kmemtrace was ported to ftrace, the marker strings were taken as
an indication of how the traced data was being exposed to the userspace.
However, the actual format had been binary, not text.

This restores the original binary format, while also adding an origin CPU
field (since ftrace doesn't expose the data per-CPU to userspace), and
re-adding the timestamp field. It also drops arch-independent field
sizing where it didn't make sense, so pointers won't always be 64 bits
wide like they used to.

kmemtrace: restore original tracing data binary format, improve ABI

When kmemtrace was ported to ftrace, the marker strings were taken as
an indication of how the traced data was being exposed to the userspace.
However, the actual format had been binary, not text.

This restores the original binary format, while also adding an origin CPU
field (since ftrace doesn't expose the data per-CPU to userspace), and
re-adding the timestamp field. It also drops arch-independent field
sizing where it didn't make sense, so pointers won't always be 64 bits
wide like they used to.

kmemtrace: use tracepoints

kmemtrace now uses tracepoints instead of markers. We no longer need to
use format specifiers to pass arguments.

kmemtrace: use tracepoints

kmemtrace now uses tracepoints instead of markers. We no longer need to
use format specifiers to pass arguments.

Signed-off-by: Eduard - Gabriel Munteanu <eduard.munteanu@linux360.ro>
[ folded: Use the new TP_PROTO and TP_ARGS to fix the build.     ]
[ folded: fix build when CONFIG_KMEMTRACE is disabled.           ]
[ folded: define tracepoints when CONFIG_TRACEPOINTS is enabled. ]

tracing: add missing 'extern' keywords to trace_output.h

Impact: cleanup

Many declarations within trace_output.h are missing the 'extern' keyword
in an inconsistent manner. This adds 'extern' where it should be.

tracing: provide trace_seq_reserve()

trace_seq_reserve() allows a caller to reserve space in a trace_seq and
write directly into it. This makes it easier to export binary data to
userspace via the tracing interface, by simply filling in a struct.

rcu: don't include unnecessary headers, allow kmemtrace w/ tracepoints

linux/percpu.h includes linux/slab.h, which generates circular inclusion
dependencies when trying to switch kmemtrace to use tracepoints instead
of markers. This patch allows tracing within slab headers' inline
functions.
