[RFC patch 00/32] TRACE_EVENT: cleanup for code-size reduction

[RFC patch 00/32] TRACE_EVENT: cleanup for code-size reduction

[Mathieu Desnoyers]

Hi,

I implemented the TRACE_EVENT macros as arrays of fields and arrays of
events in LTTng, and realised that it could benefit Ftrace too by
cutting down its code size. As I know that code size footprint is an
issue Steven has been wanting to tackle for a while, I am sending this
"semicolon removal" patchset, which is a prerequisite to be able to
generate arrays of events.

The main difference between the approaches Ftrace and LTTng have taken
is that Ftrace creates a "ftrace_define_fields_##call" function for each
event which calls trace_define_field for each field of each event. In
LTTng, I did the following (code snippet from [1]):

struct lttng_event_field {
        const char *name;
        const struct lttng_type type;
};

struct lttng_event_desc {
        const struct lttng_event_field *fields;
        const char *name;
        unsigned int nr_fields;
};

#undef DEFINE_EVENT
#define DEFINE_EVENT(_template, _name, _proto, _args)                          \
                {                                                              \
                        .fields = __event_fields___##_template,                \
                        .name = #_name,                                        \
                        .nr_fields = ARRAY_SIZE(__event_fields___##_template), \
                },

#define TP_ID1(_token, _system) _token##_system
#define TP_ID(_token, _system)  TP_ID1(_token, _system)

static const struct lttng_event_desc TP_ID(__event_desc___, TRACE_SYSTEM)[] = {
#include TRACE_INCLUDE(TRACE_INCLUDE_FILE)
};

And for creation of __event_fields___##_template, which allows to keep
all fields in another array (which should be defined in a phase prior to
the event array definition), I did:

#undef __field
#define __field(_type, _item)                                   \
        { .name = #_item, .type = { .atype = atype_integer, .name = #_type} },

(similar for __field_ext, __array, __dynamic_array, __string)

#undef TP_STRUCT__entry
#define TP_STRUCT__entry(args...) args  /* Only one used in this phase */

#undef DECLARE_EVENT_CLASS
#define DECLARE_EVENT_CLASS(_name, _proto, _args, _tstruct, _assign, _print) \
        static const struct lttng_event_field __event_fields___##_name[] = { \
                _tstruct \
        };

For the declaration of struct lttng_type, which contains the field type
information in a union, see [2].

Best regards,

Mathieu

[RFC patch 02/32] trace event sample remove semicolons, specify need for ifdef around declarations

[Mathieu Desnoyers]

[-- Attachment #1: trace-event-sample-remove-semicolons.patch --]
[-- Type: text/plain, Size: 1704 bytes --]

Part of the gradual TRACE_EVENT() semicolon removal. Enables creation of array
of events, thus saving space for trace event probes.

Protecting declarations with ifndef _TRACE_SAMPLE_DEF_ is required if we want to
ensure that, e.g., structure forward declarations do not generate extra
semicolons. It's already needed for enumerations and static inline functions
declarations, but not documented, so document it here.

[RFC patch 05/32] trace event irq remove semicolons

[Mathieu Desnoyers]

[-- Attachment #1: trace-event-irq-remove-semicolons.patch --]
[-- Type: text/plain, Size: 2199 bytes --]

Part of the gradual TRACE_EVENT() semicolon removal. Enables creation of array
of events, thus saving space for trace event probes.

[RFC patch 08/32] trace event kvm remove semicolons

[Mathieu Desnoyers]

[-- Attachment #1: trace-event-kvm-remove-semicolons.patch --]
[-- Type: text/plain, Size: 15761 bytes --]

Part of the gradual TRACE_EVENT() semicolon removal. Enables creation of array
of events, thus saving space for trace event probes.

[RFC patch 15/32] trace event sched remove trailing semicolon

[Mathieu Desnoyers]

[-- Attachment #1: trace-event-sched-remove-semicolons.patch --]
[-- Type: text/plain, Size: 6318 bytes --]

Part of the gradual TRACE_EVENT() semicolon removal. Enables creation of array
of events, thus saving space for trace event probes. Remove the trailing
semicolons at the end of TRACE_EVENT() and DEFINE_EVENT() in scheduler
instrumentation. Put __trace_sched_switch_state() static inline declaration
within ifdef protection so the preprocessor output is not polluted when creating
an array of events.

[RFC patch 24/32] trace event wireless remove semicolons

[Mathieu Desnoyers]

[-- Attachment #1: trace-event-wireless-remove-semicolons.patch --]
[-- Type: text/plain, Size: 17661 bytes --]

Part of the gradual TRACE_EVENT() semicolon removal. Enables creation of array
of events, thus saving space for trace event probes.

[RFC patch 28/32] trace event powerpc remove semicolons

[Mathieu Desnoyers]

[-- Attachment #1: trace-event-powerpc-remove-semicolons.patch --]
[-- Type: text/plain, Size: 2974 bytes --]

Part of the gradual TRACE_EVENT() semicolon removal. Enables creation of array
of events, thus saving space for trace event probes.

Can I apply this in my tree or does this depend on some earlier patch I
don't have?

This is an unrelated change and should be split out.  Frankly I'm not
that this is an improvement anyway, the struct declarations aren't going
to do any harm...

Hi Mark,

This depends on a preliminary ftrace cleanup patch I just forwarded to
you. LKML has eaten that patch due to too many CC. [ insert favorite
expression of frustration here ]. But I think the best way to proceed
would be to get a Acked-by from you and let Steven pull the patch
through the tracing tree.

Yes, this change is related, because these declarations will cause harm.
The structure declaration cannot be put within an array declaration,
because then they won't be simply "ignored": they will try to declare
structures within an array, which is not valid. This is why I did this
change in the same patch.

Thanks,

Mathieu

Hi,

And here is a self-reply to patch 01/32, due to LKML refusing messages
with more than 20 recipients.

This might make a bit more sense if we'd seen the earlier or possibly
later patches...  According to the patch description all you're doing
here is removing the semicolons.

OK, now I see patch 1 I understand why you're doing this.  It should
still be at least called out in the patch description if not actually
split out into a separate patch (which would be ideal) - one of the
things that really stands out in reviews is unrelated changes.

Sure, we can do that (for the semi-colon clean up).

No, Mark is right in this case. This IS a separate change, and deserves
a separate patch. This patch is to remove the semi-colons. This change
should be separated out and stated it is for the array. In fact, you
should probably have two different patch sets. One for the semi-colon
clean up, which I'm fine with. And another set that does more to the
patch, like this change. If I do the array change and find that it
doesn't help much, I wont want this change. But I'm willing to keep the
semi-colon change.

Yes, when I convert ftrace and perf to use arrays, then this will be
needed, but it is not needed for this series. I haven't looked at the
other patches yet (besides the first one), but if you have more of this
in other patches, please remove it. You can make another patch set that
I can use before the ftrace/perf updates.

I think you need to have two patch sets. One to do the semicolon clean
up, and one for the preparation of arrays. Again, the semi-colon cleanup
I'm fine with keeping even if we don't do the arrays. But this is only
needed if we do the array work.

I'm not even sure I want to do it this way. I may change it when I do
the array work.

I actually think there should have been two different patch sets. One
for the semi colon clean up, and the other to do the work for arrays.
The semi colon clean up is non-controversial as it is just a clean up
that does not affect the current code at all.

But the added array preparation is not needed until we do the array
work, which deserves its own patch set.

BTW, next time don't Cc the world on generic patch sets like this. If

a) You did not write your change log well enough

b) It contains unrelated changes

c) They could look at lkml.org to find out what this patch set is about.

(c) is what I usually do when I'm Cc'd in a middle of a patch series.

OTOH it's nice for maintainers to be told about stuff like this rather
than having to find out through -next failures if they do some
incremental work in the area.

Though in this case the combination of a and b undermined the
effectiveness of c.

Due to the large number of patches (32 overall), I prefer not to overdo
it in terms of splitting changes to each individual subsystem in even
more patches. If it's OK with you, I'll just clarify the changelog.

Re: [RFC patch 01/32] TRACE_EVENT: gradual semicolon removal

[Mathieu Desnoyers]

(I dropped the large CC list from this thread to fit within LKML 20 CC
list limit. I kept them in bcc so they see this message. Please feel
free to follow the rest of the thread on LKML.)

Anyone trying to ensure tracepoints are well implemented (and thus that
their resulting preprocessor output is bug-free). I did the exercise
myself, and ended up with:

commit 881fe4bdcdc899674524e30a76c76d298b447008
    tracing: remove duplicate null-pointer check in skb tracepoint
commit 23036f1a340beec19cc451ba9719526c4ffb3a57
    blktrace: add missing probe argument to block_bio_complete

so I think the preprocessor output should be more digestible by
developers, with event some documentation on how to format it so it
becomes readable. The following bash script does it for instance (I am
certain that there are ton of much better ways to do it, but this is
what I use):

#!/bin/sh

# kcpp:
# Create a .cpp file (c preprocessor output) from the same gcc
# invokation that builds an object file.

# kcpp SOURCE OBJECT
# invoke with e.g. kcpp kernel/sched.c kernel/sched.o
#  output file will be kernel/sched.cpp
# needs gcc, sed and indent

SOURCE=$1
OBJECT=$2
FILECPP=$(echo $1 | sed 's/\.c/\.cpp/')
POBJECT=$(echo ${OBJECT} | sed -e 's/\//\\\//' -e 's/\./\\\./')
PFILECPP=$(echo ${FILECPP} | sed -e 's/\//\\\//' -e 's/\./\\\./')

echo "Preprocessing ${SOURCE} -> ${FILECPP}"
echo "Object build monitored: ${OBJECT}"
touch ${SOURCE}
rm -f ${OBJECT}

CPPCMD=$(make V=1 ${OBJECT} | tail -n 1 | sed 's/ -c / -E /')
CPPCMD=$(echo ${CPPCMD} | sed "s/ -o [^ ]* / -o ${PFILECPP} /")
PCPPCMD=$(echo ${CPPCMD} | sed -e 's/"//g')
echo Invoking:
echo ${PCPPCMD}
${PCPPCMD}

echo "Formatting ${FILECPP}... "
mv ${FILECPP} ${FILECPP}.tmp
indent ${FILECPP}.tmp -o ${FILECPP}
echo "done."
echo
echo "Output preprocessor file can be found in ${FILECPP}"

I've been asked to explain myself on this topic by Frederic last time I
posted this patchset, so I added the explanation to the changelog.

Or too little, depending on the maintainer. ;-)

More seriously, I can remove pieces of changelog text if you think this
is too much. It's your call.

Yeah, I'll cut down this list. Given your explanation in another mail,
people interested to know the context of a patch should have enough
information with the patch changelog to know what is happening, and to
get to LKML to find the other relevant changes.

Thanks,

OK, I'll split those patches.

Explaining it in the cover letter is enough :)

Well, I did never asked for 1000 lines of changelog ;)
The real problem with your previous set is that your arguments were
either too weak (double ";" in generated code doesn't alone justify
a massive change like this) or too foggy (the array of field
idea was not developed enough to be understanble whereas it was the
only sane reason for this massive change).

Just explain briefly that the end goal is for storing fields in an array
with a quick example and you are done with few dozen lines for
your changelog.

People simply don't review fat changelogs.

[RFC patch 11/32] trace event module remove semicolons

[Mathieu Desnoyers]

[-- Attachment #1: trace-event-module-remove-semicolons.patch --]
[-- Type: text/plain, Size: 1799 bytes --]

Part of the gradual TRACE_EVENT() semicolon removal. Enables creation of array
of events, thus saving space for trace event probes.
