Remove the LIBTRACEEVENT_DYNAMIC and LIBTRACEFS_DYNAMIC. If
libtraceevent isn't installed or NO_LIBTRACEEVENT=1 is passed to the
build, don't compile in libtraceevent and libtracefs support. This
also disables CONFIG_TRACE that controls "perf
trace". CONFIG_TRACEEVENT is used to control enablement in
Build/Makefiles, HAVE_LIBTRACEEVENT is used in C code. Without
HAVE_LIBTRACEEVENT tracepoints are disabled and as such the commands
kmem, kwork, lock, sched and timechart are removed. The majority of
commands continue to work including "perf test".

Had just this .rej and I fixed it up manually, testing now:

Below makes it progress a bit, now to look at the perl Context stuff.

I'm adding this as a prep patch, before the 'use libtraceevent from the
system' one:

commit 8beb33f2d34d4b37c6638004fef1345bc97804fe
Author: Arnaldo Carvalho de Melo <acme@redhat.com>
Date:   Tue Dec 6 13:49:04 2022 -0300

    machine: Adopt is_lock_function() from builtin-lock.c
    
    It is used in bpf_lock_contention.c and builtin-lock.c will be made
    CONFIG_LIBTRACEEVENT=y conditional, so move it to machine.c, that is
    always available.
    
    This makes those 4 global variables for sched and lock text start and
    end to move to 'struct machine' too, as conceivably we can have that
    info for several machine instances, say some 'perf diff' like tool.

For that bpf_kwork.c see below. Now to see why the python binding is not
building, I guess is unrelated and you have some other outstanding
patch?

Its related:

I'm missing some detail, this isn't working, util/trace-event.c is still
being built and linked.

The python binding should be usable without tracepoints, in fact its
first usage was just to have access to the perf metaevents, see 
tools/perf/python/twatch.py.

You're right. I'd assumed that if you were disabling libtraceevent
then you'd also disable python. To fix the issue above you can do:

--- a/tools/perf/util/python-ext-sources
+++ b/tools/perf/util/python-ext-sources
@@ -30,7 +30,6 @@ util/rblist.c
util/counts.c
util/print_binary.c
util/strlist.c

but this needs making conditional (possibly in setup.py) on whether
libtraceevent is present or not.

Thanks,
Ian

Hi Ian, Arnaldo

With this change, does it implies that the traceevent in "tools/lib/traceevent" is not
going to be used hereafter ?

I am seeing this compile error in a system with libtracevent installed:

util/evsel.c: In function 'evsel__rawptr':
util/evsel.c:2787:36: error: 'TEP_FIELD_IS_RELATIVE' undeclared (first use in this function); did you mean 'TEP_FIELD_IS_FLAG'?
 2787 |                 if (field->flags & TEP_FIELD_IS_RELATIVE)
      |                                    ^~~~~~~~~~~~~~~~~~~~~
      |                                    TEP_FIELD_IS_FLAG
util/evsel.c:2787:36: note: each undeclared identifier is reported only once for each function it appears in


The system has libtraceevent and its devel installed.
But TEP_FIELD_IS_RELATIVE is not defined in header file of the system installed version.
Whereas it is there in header file in tools/lib/traceevent


# grep TEP_FIELD_IS_RELATIVE /usr/include/traceevent/event-parse.h
# grep TEP_FIELD_IS_RELATIVE ../lib/traceevent/event-parse.h
	TEP_FIELD_IS_RELATIVE	= 256,

# rpm -qa|grep libtraceevent
libtraceevent-1.1.1-8.el9.ppc64le
libtraceevent-devel-1.1.1-8.el9.ppc64le

How we can handle this ?


Thanks
Athira

Hi,

Observed similar issue with “builtin-trace.c”

In system without libtraceevent-devel, I could still see builtin-trace trying to get
compiled and hitting error. In my understanding, CONFIG_TRACE will be
disabled when libtraceevent is not present and hence builtin-trace should be disabled
which I am not seeing.

# rpm -qa|grep libtraceevent
libtraceevent-1.2.1-1.el8.ppc64le

# grep -i traceevent FEATURE-DUMP 
feature-libtraceevent=0

Snippet from make logs:

builtin-trace.c:266:50: error: dereferencing pointer to incomplete type 'struct tep_format_field'
  return __tp_field__init_uint(field, format_field->size, format_field->offset, needs_swap);
                                                  ^~
builtin-trace.c: In function 'evsel__syscall_arg_fmt':
builtin-trace.c:361:25: error: 'struct evsel' has no member named 'tp_format'
   et->fmt = calloc(evsel->tp_format->format.nr_fields, sizeof(struct syscall_arg_fmt));


Thanks
Athira

Hi,

Observed build failure in powerpc with NO_LIBTRACEEVENT due to kvm-stat.c compile fail.
CONFIG_TRACEEVENT  check is also needed in arch/powerpc/util/Build to fix this. Patch below:

From e06f020f66435649c10fb7d391922f687d5b8206 Mon Sep 17 00:00:00 2001
From: Athira Rajeev <atrajeev@linux.vnet.ibm.com>
Date: Wed, 7 Dec 2022 16:46:30 +0530
Subject: [PATCH] tools/perf/arch/powerpc: Disable kvm-stat when traceevent is
 disabled
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

commit 407bb16c1a32 ("perf build: Use libtraceevent from the system")
disables libtraceevent support when f libtraceevent isn't installed
or NO_LIBTRACEEVENT=1 is passed. Commit added CONFIG_TRACEEVENT check
for kvm-stat in x86/util/Build. But same has to be added in powerpc
as well. Otherwise build will fail as below:

	#make NO_LIBTRACEEVENT=1
	arch/powerpc/util/kvm-stat.c: In function 'hcall_event_get_key':
arch/powerpc/util/kvm-stat.c:42:20: error: implicit declaration of function 'evsel__intval'; did you mean 'evsel__env'? [-Werror=implicit-function-declaration]
   42 |         key->key = evsel__intval(evsel, sample, "req");
      |                    ^~~~~~~~~~~~~
      |                    evsel__env

Patch adds the check for CONFIG_TRACEEVENT in powerpc/util/Build.

Ok, I fixed this by removing the util/trace-event.c file at setup.py
time, and removing it from the list of dependencies for python.so build,
etc.

With what I have at tmp.perf/core I'm being able to build with
combinations of:

- Having or not libtraceevent-devel installed

- Using NO_LIBTRACEEVENT=1

- The default build

All mixed up, but I wasn't so judicious so far, we need to add an entry
with NO_LIBTRACEVENT=1 to tools/perf/tests/, etc.

One thing I'm doing now is testing with the container builds, and I'm
afraid we have to delay deleting the in-kernel old copy of
tools/lib/traceevent till distros that don't ship libtraceevent as a
separate package are EOLed.

We need in those cases to fallback to tools/lib/traceevent/, with a
warning probably.

I'm now updating my container build recipes to install
libtraceevent-devel, when available, which isn't the case, for instance,
for almalinux:8, the first I tried updating.

Please take a look at:

https://git.kernel.org/pub/scm/linux/kernel/git/acme/linux.git/commit/?h=tmp.perf/core

The HEAD for that branch has the list of changes I made to get this
going.

Also I have the feeling the warning about libtraceevent not being
available should be made more proeminent and detailed in what gets
removed if this new, important dependency isn't met...

I agree removing libtraceevent and adding yet another dependency to
building perf is important since the libtraceevent maintainers took the
decision of having it moved away from the kernel sources, but since this
has been a no-brainer for so long, the fallout of this decision may be
noticeable.

At least by now we have clear markings of where libtraceevent is used.

Thanks,

- Arnaldo

No distro I tested so far has a package for libtracevent in is default
repositories:

almalinux 8 and 9 and the recently released Alpine Linux 3.17 (at least
I hadn't a recipe for that one, will try with edge).

Not sure what you mean by "default repository".

At least on Debian testing, I have libtraceevent-dev available.

Right, I'm talking about non-bleeding edge, distros that are still
supported. I'm still checking, fedora is ok all the way back to 33, wrt
having libtraceevent available.

And in some places libtraceevent is available, but then:

I think this is both similar to the python2 issue and different. With
python we now have a build time dependency on having at least Python
3.6 if you want json events. With this change you need the system to
have libtraceevent if you want to have various commands like perf
sched, perf trace, etc. Losing entire commands with this change is
more than happened with the Python 3.6 dependency. With the python
issue, you can fix the build issue by installing Python 3.6 and with
this issue you can fix it by installing libtraceevent-devel. In both
cases you can install via a package manager, but given you are likely
building the perf tool from source, you can also build both python and
libtraceevent from source. Saying that an old distro is broken by this
change, or the Python 3.6 change, I think is too strong and we're in
danger of holding things back for a very small (possibly 0) set of
people. They'd have to be upset about building from source on an old
distro, then losing the less commonly used commands of perf sched,
perf trace, etc. and be unwilling to build libtraceevent from source.
Given they are building the perf tool from source I just can't imagine
they'd be too upset about building libtraceevent from source.

I think a problem with both changes is that the build time warning
given isn't loud enough. Perhaps we can make it that at build time we
$(error for these recommended dependencies, unless NO_JEVENTS=1 or
NO_LIBTRACEEVENT=1 are added. Losing functionality and just having a
small $(warning seems error prone and likely to cause functionality to
be accidentally lost.

Thanks,
Ian

Can you try again? tmp.perf/core? That "tmp." part means its a force
pushed branch, so I just force pushed with some arch specific fixes, now
I'm down to (removing the successful builds and unrelated failures, now
related to libbpf's F_DUPFD_CLOEXEC kaboom):

I observed same issue as updated here: 
https://lore.kernel.org/lkml/10476A85-3F75-4C91-AB5B-E5B136F31297@linux.vnet.ibm.com/

Looks like TEP_FIELD_IS_RELATIVE is not defined in header file of the system installed version.
whereas it is there in header file in tools/lib/traceevent

# grep TEP_FIELD_IS_RELATIVE /usr/include/traceevent/event-parse.h
# grep TEP_FIELD_IS_RELATIVE ../lib/traceevent/event-parse.h
	TEP_FIELD_IS_RELATIVE	= 256,


Thanks

Right, I had noticed that as well, so as a prep patch I'm adding the
patch below, before Ian's. Please check and provide an
Acked-by/Tested-by/Reviewed-by if possible.

commit d288f6c03038e8f14f0b53bd4ccc03f664c8c744
Author: Arnaldo Carvalho de Melo <acme@redhat.com>
Date:   Thu Dec 8 18:26:05 2022 -0300

    perf tools: Add test to check if libtracevent has TEP_FIELD_IS_RELATIVE
    
    Some distros have older versions of libtraceevent where
    TEP_FIELD_IS_RELATIVE and its associated semantics are not present, so
    we need to test for its presence and cope when it isn't present when
    building with LIBTRACEEVENT_DYNAMIC=1.

I ended up with the one below, _after_ Ian's patch as I had some trouble grafting
it before and had already tested it this way multiple times, I'm pushing
this to tmp/perf.core.

commit a0ec3ef4590e7e82339b6f318e671a6b69fd94e8
Author: Arnaldo Carvalho de Melo <acme@redhat.com>
Date:   Thu Dec 8 19:28:58 2022 -0300

    perf tools: Add test to check if libtracevent has TEP_FIELD_IS_RELATIVE
    
    Some distros have older versions of libtraceevent where
    TEP_FIELD_IS_RELATIVE and its associated semantics are not present, so
    we need to test for its presence and cope when it isn't present when
    building with LIBTRACEEVENT_DYNAMIC=1.

Could HAVE_LIBTRACEEVENT_TEP_FIELD_IS_RELATIVE be a version rather
than feature check, something like:

#define MAKE_LIBTRACEEVENT_VERSION(maj, mid, min) (maj * 255 *255 +
mid * 255 + min)
#define HAVE_LIBTRACEEVENT_TEP_FIELD_IS_RELATIVE
(LIBTRACEEVENT_VERSION >= MAKE_LIBTRACEEVENT_VERSION(1, 5, 0)

Note, we have LIBTRACEEVENT_VERSION computed in Makefile.config by way
of pkg-config.

Thanks,
Ian

LIBTRACEEVENT_VERSION had a workaround if pkg-config wasn't present to
default to 1.1.0 for its use in:
https://lore.kernel.org/linux-perf-users/20210923001024.550263-4-irogers@google.com/
We should un-revert that change now the -Itools/lib issue is resolved
(1.1 traceevent headers compiled against newer system libtraceevent
library).

Hi Arnaldo, Ian

Thanks for the fixes.

Since we changed “CONFIG_TRACEEVENT” to “CONFIG_LIBTRACEEVENT”, 
below change is also needed in “arch/powerpc/util/Build”

diff --git a/tools/perf/arch/powerpc/util/Build b/tools/perf/arch/powerpc/util/Build
index 71e57f28abda..9889245c555c 100644

+perf-$(CONFIG_LIBTRACEEVENT) += kvm-stat.o
 perf-y += perf_regs.o

 perf-y += sym-handling.o

With this change, I could successfully compile in these environment:
- Without libtraceevent-devel installed
- With libtraceevent-devel installed
- With “make NO_LIBTRACEEVENT=1”

With above change,

I did that and the same thing for other architectures, thanks for
testing!

I'll now give a try at implementing it without
tools/build/feature/test-libtraceevent-tep_field_is_relative.c, using
just the version of libtraceevent, as Ian suggested.

It would be great if you could test it again then,

Thanks,

Can you please send that un-revert as a proper patch?

Meanwhile, I came up with this quick hack on top of what I had, seems to
be enough, will test it with systems with libtraceevent <= 1.5.0, where
TEP_FIELD_IS_RELATIVE was introduced.

Will do it after removing the tools/build/feature/ TEP_FIELD_IS_RELATIVE
big hammer check.

Thanks Athira and Arnaldo. It is a little strange to me to be using
the shell to do a version number test. The intent was to be doing
these in the code:
#if LIBRTRACEEVENT_VERSION >= MAKE_LIBTRACEEVENT_VERSION(1, 5, 0)
vs
...
LIBTRACEEVENT_VERSION_WITH_TEP_FIELD_IS_RELATIVE := $(shell expr 1 \*
255 \* 255 + 5 \* 255 + 0) # 1.5.0
ifeq ($(shell test $(LIBTRACEEVENT_VERSION_CPP) -gt
$(LIBTRACEEVENT_VERSION_WITH_TEP_FIELD_IS_RELATIVE); echo $$?),0)
CFLAGS += -DHAVE_LIBTRACEEVENT_TEP_FIELD_IS_RELATIVE
endif
...
#ifdef HAVE_LIBTRACEEVENT_TEP_FIELD_IS_RELATIVE
I'm a little selfish as I'm maintaining a bazel build and a single
version number to maintain is easier than lots of HAVE_... tests. I'm
happy to follow Arnaldo's lead. I think the test should also be
greater-equal rather than greater-than:
https://git.kernel.org/pub/scm/libs/libtrace/libtraceevent.git/tree/include/traceevent/event-parse.h?h=libtraceevent-v1.5#n128

Ian

I'll fix that, and in a case like this please consider to send a patch with your preference, I'd happily
graft it.

I can fix it. I can fold it in with:
https://lore.kernel.org/linux-perf-users/20210923001024.550263-4-irogers@google.com/
which I mentioned in this thread.
