perf tools: Define _GNU_SOURCE on pthread_attr_setaffinity_np feature check (2015-02-11 17:38:55 -0300)
----------------------------------------------------------------
perf/core improvement and fixes:
User visible:
- No need to explicitely enable evsels for workload started from perf, let it
be enabled via perf_event_attr.enable_on_exec, removing some events that take
place in the 'perf trace' before a workload is really started by it.
(Arnaldo Carvalho de Melo)
- Fix to handle optimized not-inlined functions in 'perf probe' (Masami Hiramatsu)
- Update 'perf probe' man page (Masami Hiramatsu)
Infrastructure:
Arnaldo Carvalho de Melo (4):
- Introduce {trace_seq_do,event_format_}_fprintf functions to allow
a default tracepoint field list printer to be used in tools that allows
redirecting output to a file. (Arnaldo Carvalho de Melo)
- The man page for pthread_attr_set_affinity_np states that _GNU_SOURCE
must be defined before pthread.h, do it to fix the build in some
systems (Josh Boyer)
- Cleanups in 'perf buildid-cache' (Masami Hiramatsu)
- Fix dso cache test case (Namhyung Kim)
- Do Not rely on dso__data_read_offset() to open DSO (Namhyung Kim)
- Make perf aware of tracefs (Steven Rostedt).
- Fix build by defining STT_GNU_IFUNC for glibc 2.9 and older (Vinson Lee)
- AArch64 symbol resolution fixes (Victor Kamensky)

Aarch64 ELF files use mapping symbols with special names $x, $d
to identify regions of Aarch64 code (see Aarch64 ELF ABI - "ARM
IHI 0056B", section "4.5.4 Mapping symbols").
The patch filters out these symbols at load time, similar to
"696b97a perf symbols: Ignore mapping symbols on ARM" changes
done for ARM before V8.
Also added handling of mapping symbols that has format
"$d.<any>" and similar for both cases.
Note we are not making difference between EM_ARM and
EM_AARCH64 mapping symbols instead code handles superset
of both.

Currently code that tries to read corresponding debug symbol file from
.gnu_debuglink section (DSO_BINARY_TYPE__DEBUGLINK) does not take in
account symfs option, so filename__read_debuglink function cannot open
ELF file, if symfs option is used.
Fix is to add proper handling of symfs as it is done in other places:
use __symbol__join_symfs function to get real file name of target ELF
file.

Hi Arnaldo, Ingo,
What happened with this pull request? I already
see in v4.0-rc2 changes additions to one requested
by this pull request, but I don't see this series itself.
For example e370a3d57664cd5e39c0b95d157ebc841b568409
"perf symbols: Define EM_AARCH64 for older OSes" by David
is already in v4.0-rc2 and it is supposed to be addition to
"perf symbols: Ignore mapping symbols on aarch64" that is part
of this pull request but it did not make into v4.0-rcX yet. Looks
quite strange.
Thanks,
Victor

If some commits of the v4.1 queue are needed in v4.0 as well then they
should be cherry-picked back into the urgent queue.
But maybe e370a3d57 was merged prematurely - in that case it appears
to be harmless and v4.1 will sort it out.
Arnaldo?

Yes, this merge is harmless. Indeed it should be OK with v4.1.

perf trace: Do not require --no-syscalls to suppress strace like output (2018-08-01 16:20:28 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
perf trace: (Arnaldo Carvalho de Melo)
- Do not require --no-syscalls to suppress strace like output, i.e.
# perf trace -e sched:*switch
will show just sched:sched_switch events, not strace-like formatted
syscall events, use --syscalls to get the previous behaviour.
If instead:
# perf trace
is used, i.e. no events specified, then --syscalls is implied and
system wide strace like formatting will be applied to all syscalls.
The behaviour when just a syscall subset is used with '-e' is unchanged:
# perf trace -e *sleep,sched:*switch
will work as before: just the 'nanosleep' syscall will be strace-like
formatted plus the sched:sched_switch tracepoint event, system wide.
- Allow string table generators to use a default header dir, allowing
use of them without parameters to see the table it generates on
stdout, e.g.:
$ tools/perf/trace/beauty/kvm_ioctl.sh
static const char *kvm_ioctl_cmds[] = {
[0x00] = "GET_API_VERSION",
[0x01] = "CREATE_VM",
[0x02] = "GET_MSR_INDEX_LIST",
[0x03] = "CHECK_EXTENSION",
<BIG SNIP>
[0xe0] = "CREATE_DEVICE",
[0xe1] = "SET_DEVICE_ATTR",
[0xe2] = "GET_DEVICE_ATTR",
[0xe3] = "HAS_DEVICE_ATTR",
};
$
See 'ls tools/perf/trace/beauty/*.sh' to see the available string
table generators.
- Add a generator for IPPROTO_ socket's protocol constants.
perf record: (Kan Liang)
- Fix error out while applying initial delay and using LBR, due to
the use of a PERF_TYPE_SOFTWARE/PERF_COUNT_SW_DUMMY event to track
PERF_RECORD_MMAP events while waiting for the initial delay. Such
events fail when configured asking PERF_SAMPLE_BRANCH_STACK in
perf_event_attr.sample_type.
perf c2c: (Jiri Olsa)
- Fix report crash for empty browser, when processing a perf.data file
without events of interest, either because not asked for in
'perf record' or because the workload didn't triggered such events.
perf list: (Michael Petlan)
- Align metric group description format with PMU event description.
perf tests: (Sandipan Das)
- Fix indexing when invoking subtests, which caused BPF tests to
get results for the next test in the list, with the last one
reporting a failure.
eBPF:
- Fix installation directory for header files included from eBPF proggies,
avoiding clashing with relative paths used to build other software projects
such as glibc. (Thomas Richter)
- Show better message when failing to load an object. (Arnaldo Carvalho de Melo)
General: (Christophe Leroy)
- Allow overriding MAX_NR_CPUS at compile time, to make the tooling
usable in systems with less memory, in time this has to be changed
to properly allocate based on _NPROCESSORS_ONLN.
Architecture specific:
- Update arm64's ThunderX2 implementation defined pmu core events (Ganapatrao Kulkarni)
- Fix complex event name parsing in 'perf test' for PowerPC, where the 'umask' event
modifier isn't present. (Sandipan Das)
CoreSight ARM hardware tracing: (Leo Yan)
- Fix start tracing packet handling.
- Support dummy address value for CS_ETM_TRACE_ON packet.
- Generate branch sample when receiving a CS_ETM_TRACE_ON packet.
- Generate branch sample for CS_ETM_TRACE_ON packet.

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, 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.
