  perf tools: Fix LIBNUMA build with glibc 2.12 and older. (2013-03-14 08:06:21 -0300)

----------------------------------------------------------------
perf/urgent fixes:

. perf probe: Fix segfault due to testing the wrong pointer for NULL,
  from Ananth N Mavinakayanahalli.

. libtraceevent: Remove hard coded include to /usr/local/include in
  Makefile, which causes cross builds to include host header files,
  fix from Jack Mitchell.

. perf record: Use the right target interface for synthesizing
  threads when --cpu/-C option is used, fix from Jiri Olsa.

. Check if -DFORTIFY_SOURCE=2 is allowed, as gcc 4.7.2 defines
  it and then the build is broken when it is redefined in perf,
  fix from Marcin Slusarz.

. Fix build with NO_NEWT=1, that can happen explicitely or when
  the newt-devel package is not installed, from Michael Ellerman.

. perf/POWER7: Create a sysfs format entry for Power7 events, missing
  patch from a patchseries already merged, from Sukadev Bhattiprolu.

. Fix LIBNUMA build with glibc 2.12 and older, from Vinson Lee.

From: Michael Ellerman <michael@ellerman.id.au>

Commit 18c9e5c "Make it to be able to skip unannotatable symbols" broke
the build with NO_NEWT=1:

   CC builtin-annotate.o
builtin-annotate.c: In function 'hists__find_annotations':
builtin-annotate.c:161:4: error: duplicate case value
builtin-annotate.c:154:4: error: previously used here
make: *** [builtin-annotate.o] Error 1

This is because without NEWT support K_LEFT is #defined to -1 in
utils/hist.h

Fix it by shifting the K_LEFT/K_RIGHT #defines out of the likely range
of error values.

From: Marcin Slusarz <marcin.slusarz@gmail.com>

It seems gcc (4.7.2) defines _FORTIFY_SOURCE internally and becomes
confused when it sees another definition in flags.

For me, build failed like this:

CHK glibc
Makefile:548: *** No gnu/libc-version.h found, please install glibc-dev[el]/glibc-static. Stop.

and only with V=1 it printed:

<command-line>:0:0: error: "_FORTIFY_SOURCE" redefined [-Werror]
<stdin>:1:0: note: this is the location of the previous definition

From: Jiri Olsa <jolsa@redhat.com>

Currently the -C option does not work for record command, because of the
targets mismatch when synthesizing threads.

Fixing this by using proper target interface for the synthesize
decision.

having /usr/local/include hardcoded into the makefile is not necessary
as this is automatically included by GCC. It also infects cross-compile
builds with the host systems includes.

From: Sukadev Bhattiprolu <sukadev@linux.vnet.ibm.com>

Create a sysfs entry, '/sys/bus/event_source/devices/cpu/format/event'
which describes the format of the POWER7 PMU events.

This code is based on corresponding code in x86.

Changelog[v4]:  [Michael Ellerman, Paul Mckerras] The event format is different
		for other POWER cpus. So move the code to POWER7-specific,
		power7-pmu.c Also, the POWER7 format uses bits 0-19 not 0-20.

Changelog[v2]: [Jiri Osla] Use PMU_FORMAT_ATTR rather than duplicating code.

		for other POWER cpus. So move the code to POWER7-specific,
		power7-pmu.c Also, the POWER7 format uses bits 0-19 not 0-20.

Changelog[v2]: [Jiri Osla] Use PMU_FORMAT_ATTR rather than duplicating code.

The tokens MADV_HUGEPAGE and MADV_NOHUGEPAGE are not available with
glibc 2.12 and older. Define these tokens if they are not already
defined.

This patch fixes these build errors with older versions of glibc.

    CC bench/numa.o
bench/numa.c: In function ‘alloc_data’:
bench/numa.c:334: error: ‘MADV_HUGEPAGE’ undeclared (first use in this function)
bench/numa.c:334: error: (Each undeclared identifier is reported only once

Hi Ingo,

	As requested I merged tip/perf/core with this branch and now its
available as the perf-urgent-for-mingo-5.3-20190708-2 signed tag, that
has only one extra cset:

  commit 686cbe9e5d88ad639bbe26d963e7d5dafa1c1c28 (HEAD -> perf/urgent, tag: perf-urgent-for-mingo-5.3-20190708-2, acme/perf/urgent, acme.korg/perf/urgent)
  Author: Arnaldo Carvalho de Melo <acme@redhat.com>
  Date:   Mon Jul 8 13:47:14 2019 -0300
  
      tools arch x86: Sync asm/cpufeatures.h with the with the kernel

Best regards,

Hi Ingo,

	Please consider pulling, I did a git merge with torvalds/master
late last week to fixup some kernel headers ABI sync warnings, but I had
to cherry pick some csets from my perf/core branch to get the container
builds to all work, so ended up slipping past v5.2, oh well, but here it
is, all containers building ok, I'll now test perf/core to then push
that too.

Best regards,

- Arnaldo

  tools build: Check if gettid() is available before providing helper (2019-07-07 17:53:09 -0300)

----------------------------------------------------------------
perf/urgent fixes:

core:

  Arnaldo Carvalho de Melo:

  - Allow references to thread objects after__machine_exit(), fixing a bug with
    'perf sched lat' where that happens, i.e. after perf_session__delete() we
    still have references to threads that were in a linked list whose head was
    freed in perf_session__delete(), causing a segfault, fix it.

  Jiri Olsa:

  - Do not rely on errno values for precise_ip fallback, fixing the default
    use case for 'perf record' on some AMD servers, when no events are specified
    and we try to use "cycles:P", i.e. with the maximum precision level.

BPF:

  Song Liu:

  - Assign proper ff->ph in perf_event__synthesize_features(), fixing a bug
    when using pipe mode, i.e.  'perf record -o -'.

tools headers:

  Arnaldo Carvalho de Melo:

  - Sync kvm headers with the kernel sources

perf tests:

  Seeteena Thoufeek:

  - Fix record+probe_libc_inet_pton.sh for powerpc64, where without the
    debuginfo package for the 'ping' utility we can't resolve its symbols,
    so admit getting "[unknown]" for that backtrace line.

perf python:

  Arnaldo Carvalho de Melo:

  - Remove -fstack-protector-strong if clang doesn't have it, fixing the build
    with clang on fedora:30, oracleline:7, centos:7.

perf jvmti:

  Jiri Olsa:

  - Address gcc string overflow warning for strncpy()

build:

  Arnaldo Carvalho de Melo:

  - Check if gettid() is available before providing helper, as recent
    versions of glibc started to provide gettid().

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

The '41: BPF filter' 'perf test' entry is being investigated, it
shouldn't be with "Skip" status, some problem with BPF maps.

  perf script python: Add Python3 support to tests/attr.py (2019-02-05 10:31:08 -0300)

----------------------------------------------------------------
perf/urgent fixes:

perf trace:

  Arnaldo Carvalho de Melo:

    Fix handling of probe:vfs_getname when the probed routine is
    inlined in multiple places, fixing the collection of the 'filename'
    parameter in open syscalls.

perf test:

  Gustavo A. R. Silva:

    Fix bitwise operator usage in evsel-tp-sched test, which made tat
    test always detect fields as signed.

  Jiri Olsa:

    Filter out hidden symbols from labels, added in systems where the
    annobin plugin is used, such as RHEL8, which, if left in place make
    the DWARF unwind 'perf test' to fail on PPC.

  Tony Jones:

    Fix 'perf_event_attr' tests when building with python3.

perf mem/c2c:

  Ravi Bangoria:

    Fix perf_mem_events on PowerPC.

tools headers UAPI:

  Arnaldo Carvalho de Melo:

    Sync linux/in.h copy from the kernel sources, silencing a perf build warning.

Test results:

The first ones are container based builds of tools/perf with and without libelf
support.  Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Test results:

The first ones are container (docker) based builds of tools/perf with and
without libelf support.  Where clang is available, it is also used to build
perf with/without libelf.

The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.

Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.

The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.

Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.

Pulled, thanks a lot Arnaldo!

I'll get this to Linus ASAP.

Note: got a conflict with perf/core in tools/perf/Makefile, when 
merging in tip:master. It appeared to me that perf/core already 
included all the changes to BASIC_CFLAGS that perf/urgent 
updated, so I picked the perf/core version.

The merged result seems to work fine but please double check it 
nevertheless.

Thanks,

	Ingo

Pulled, thanks a lot Arnaldo!

I'll get this to Linus ASAP.

Note: got a conflict with perf/core in tools/perf/Makefile, when 
merging in tip:master. It appeared to me that perf/core already 
included all the changes to BASIC_CFLAGS that perf/urgent 
updated, so I picked the perf/core version.

The merged result seems to work fine but please double check it 
nevertheless.

Thanks,

	Ingo

I probably sound like a broken record at this point, but I've not seen
this go into any tip branch, nor is it in Linus' tree.  Hopefully this
gets pulled before 3.7 is released.
