Subject: [GIT PULL 00/18] perf/core improvements and fixes
Hi Ingo,
Please consider pulling,
- Arnaldo
Test results at the end of this message, as usual.
The following changes since commit 9df9078ef2086652647248ee6e82ca8f661cb3f5:
perf/amd/uncore: Fix pr_fmt() prefix (2017-04-11 08:44:59 +0200)

perf annotate: Use stripped line instead of raw disassemble line (2017-04-11 16:22:23 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
User visible:
- Support s390 jump instructions in perf annotate (Christian Borntraeger)
- When failing to setup multiple events (e.g. '-e irq_vectors:*'), state
which one caused the failure (Yao Jin)
- Various fixes for pipe mode, where the output of 'perf record' is
written to stdout instead of to a perf.data file, fixing workloads
such as: (David Carrillo-Cisneros)
$ perf record -o - noploop | perf inject -b > perf.data
$ perf record -o - noploop | perf annotate
Infrastructure:
- Simplify ltrim() implementation (Arnaldo Carvalho de Melo)
- Use ltrim() and rtrim() in places where ad-hoc equivalents were being
used (Taeung Song)
Signed-off-by: Arnaldo Carvalho de Melo <acme@...hat.com>
----------------------------------------------------------------
Arnaldo Carvalho de Melo (3):
perf callchains: Switch from strtok() to strtok_r() when parsing options
perf script: Use strtok_r() when parsing output field list
perf string: Simplify ltrim() implementation
Christian Borntraeger (2):
perf annotate s390: Fix perf annotate error -95 (4.10 regression)
perf annotate s390: Implement jump types for perf annotate
David Carrillo-Cisneros (6):
perf inject: Don't proceed if perf_session__process_event() fails
perf inject: Copy events when reordering events in pipe mode
perf tools: Describe pipe mode in perf.data-file-fomat.txt
perf annotate: Process attr and build_id records
perf session: Don't rely on evlist in pipe mode
perf tools: Do not print missing features in pipe-mode
Jin Yao (1):
perf evsel: Return exact sub event which failed with EPERM for wildcards
Taeung Song (6):
perf stat: Refactor the code to strip csv output with ltrim()
perf ui browser: Refactor the code to parse color configs with ltrim()
perf pmu: Refactor wordwrap() with ltrim()
perf tools: Refactor the code to strip command name with {l,r}trim()
perf annotate: Refactor the code to parse disassemble lines with {l,r}trim()
perf annotate: Use stripped line instead of raw disassemble line

Test results:
The first ones are container (docker) based builds of tools/perf with and
without libelf support, objtool where it is supported and samples/bpf/, ditto.
Where clang is available, it is also used to build perf with/without libelf.
For this specific pull request the samples/bpf/ was disabled, as 'make headers_install'
is failing with the following error, in this case in fedora:rawhide:
INSTALL usr/include/uapi/ (0 file)
/git/linux/scripts/Makefile.headersinst:62: *** Missing generated UAPI file ./arch/x86/include/generated/uapi/asm/unistd_32.h. Stop.
make[1]: *** [/git/linux/Makefile:1151: headers_install] Error 2
make[1]: Leaving directory '/tmp/build/linux'
make: *** [Makefile:152: sub-make] Error 2
make: Leaving directory '/git/linux'
I'll investigate later, perf and objtool builds just fine, with clang and gcc.
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.
