[PATCH 00/12] libperf: Add events to perf/event.h

[PATCH 00/12] libperf: Add events to perf/event.h

[Jiri Olsa]

hi,
as a preparation for sampling libperf interface, moving event
definitions into the library header. Moving just the kernel 
non-AUX events now.

In order to keep libperf simple, we switch 'u64/u32/u16/u8'
types used events to their generic '__u*' versions.

Perf added 'u*' types mainly to ease up printing __u64 values
as stated in the linux/types.h comment:

  /*
   * We define u64 as uint64_t for every architecture
   * so that we can print it with "%"PRIx64 without getting warnings.
   *
   * typedef __u64 u64;
   * typedef __s64 s64;
   */

Adding and using new PRI_lu64 and PRI_lx64 macros to be used for
that.  Using extra '_' to ease up the reading and differentiate
them from standard PRI*64 macros.

It's also available in here:
  git://git.kernel.org/pub/scm/linux/kernel/git/jolsa/perf.git
  perf/fixes

thanks,
jirka

[tip: perf/core] libperf: Add PERF_RECORD_MMAP 'struct mmap_event' to perf/event.h

   */

Add  and use new PRI_lu64 and PRI_lx64 macros for that.  Use extra '_'
to ease up reading and differentiate them from standard PRI*64 macros.

Committer notes:

Fixup the PRI_l[ux]64 macros on 32-bit arches, conditionally defining it
with that extra 'l' modifier only on arches where __u64 is long long,
leaving it aside on 32-bit arches.

libperf: Add PERF_RECORD_LOST 'struct lost_event' to perf/event.h

Move the lost_event event definition to libperf's event.h header
include.

In order to keep libperf simple, we switch 'u64/u32/u16/u8' types used
events to their generic '__u*' versions.

Perf added 'u*' types mainly to ease up printing __u64 values as stated
in the linux/types.h comment:

  /*
   * We define u64 as uint64_t for every architecture
   * so that we can print it with "%"PRIx64 without getting warnings.
   *
   * typedef __u64 u64;
   * typedef __s64 s64;
   */

Add and use new PRI_lu64 and PRI_lx64 macros for that.  Use extra '_' to
ease up the reading and differentiate them from standard PRI*64 macros.

[PATCH 07/12] libperf: Add lost_samples_event to perf/event.h

[Jiri Olsa]

Moving lost_samples_event event definition into libperf's event.h
header include.

In order to keep libperf simple, we switch 'u64/u32/u16/u8'
types used events to their generic '__u*' versions.

Perf added 'u*' types mainly to ease up printing __u64 values
as stated in the linux/types.h comment:

  /*
   * We define u64 as uint64_t for every architecture
   * so that we can print it with "%"PRIx64 without getting warnings.
   *
   * typedef __u64 u64;
   * typedef __s64 s64;
   */

Adding and using new PRI_lu64 and PRI_lx64 macros to be used for
that.  Using extra '_' to ease up the reading and differentiate
them from standard PRI*64 macros.

[PATCH 10/12] libperf: Add ksymbol_event to perf/event.h

[Jiri Olsa]

Moving ksymbol_event event definition into libperf's event.h
header include.

In order to keep libperf simple, we switch 'u64/u32/u16/u8'
types used events to their generic '__u*' versions.

Perf added 'u*' types mainly to ease up printing __u64 values
as stated in the linux/types.h comment:

  /*
   * We define u64 as uint64_t for every architecture
   * so that we can print it with "%"PRIx64 without getting warnings.
   *
   * typedef __u64 u64;
   * typedef __s64 s64;
   */

Adding and using new PRI_lu64 and PRI_lx64 macros to be used for
that.  Using extra '_' to ease up the reading and differentiate
them from standard PRI*64 macros.

I think we should take advantage of this moment to rename those structs
to have the 'perf_record_' prefix on them, I guess we could even remove
the _event from them, i.e.:

'struct mmap_event' becomes 'perf_record_mmap', as it is the description
for the PERF_RECORD_MMAP meta-data event, are you ok with that?

I can go ahead and do it myself, updating each patch on this series to
do that.

hum, not sure about loosing the '_event' here, but we are
not public yet, so we can always change back ;-) I do like
it'd follow the enum name

sure, I thought we'd do it later, but feel free to do it,
maybe in separate changes?

So I'm making the already exported to libperf to be renamed to have the
same name as the PERF_RECORD_ enum they map to, just all lowercase.

Looks nice and also makes something exported by libperf to have a perf_
namespace prefix.

BTW: you forgot to move PERF_RECORD_CONTEXT_SWITCH :-)

I did it as a separate patch, one patch for all the PERF_RECORD_ already
moved to libperf.

Also some other minor stuff, like having that
perf_event.{bpf,ksymbol}_event renamed to play perf_event.{bpf,ksymbol},
like the other records. so to make this idiom more compact and less
redundant:

    event->bpf_event

becomes:

    event->bpf

ditto for ksymbol_event.

It doesn't build on the r15b as well.

$ make $EXTRA_MAKE_ARGS ARCH=$ARCH CROSS_COMPILE=$CROSS_COMPILE EXTRA_CFLAGS="$EXTRA_CFLAGS" -C /git/perf/tools/perf O=/tmp/build/perf /tmp/build/perf/builtin-sched.i

We end up with one 'l' too many?

[perfbuilder@490c2c7bdaab ~]$ grep 'printf("lost' /tmp/build/perf/builtin-sched.i
 printf("lost %" "l" "ll""u" " events on cpu %d\n", event->lost.lost, sample->cpu);
[perfbuilder@490c2c7bdaab ~]$

And if we do this on a fedora:30 x86_64:

$ make -C tools/perf O=/tmp/build/perf /tmp/build/perf/builtin-sched.i
[acme@quaco perf]$ grep -A4 'printf("lost' /tmp/build/perf/builtin-sched.i
 printf("lost %" "l" 
# 2646 "builtin-sched.c" 3 4
                "l" "u" 
# 2646 "builtin-sched.c"
                         " events on cpu %d\n", event->lost.lost, sample->cpu);
[acme@quaco perf]$

I.e. on 32-bit arches we shouldn't add that extra "l", right?

I bet the build for the mips/mipsel will fail too, lemme see... Yeah,
both failed:


[root@quaco ~]# grep -m1 -A6 -- -Werror=format=  dm.log/debian\:experimental-x-mips

hum, I guess we could #ifdef it 64/32 bits

I tried to figure out how to fix this better, but the int-ll64.h versus
int-l64.h versus how __u64 is defined got me confused and I ended up
with:

#if __WORDSIZE == 64
/*
 * /usr/include/inttypes.h uses just 'lu' for PRIu64, but we end up defining
 * __u64 as long long unsigned int, and then -Werror=format= kicks in and
 * complains of the mismatched types, so use these two special extra PRI
 * macros to overcome that.
 */
#define PRI_lu64 "l" PRIu64
#define PRI_lx64 "l" PRIx64
#else
#define PRI_lu64 PRIu64
#define PRI_lx64 PRIx64
#endif

Builds in all the containers I have, 32-bit, 64-bit, old gccs/clangs,
new ones, uclibc, musl libc, glibc, etc

Make that:

#ifdef __LP64__ to build on Alpine/musl libc.
