Test results at the end of this message, as usual.
The following changes since commit 1159e09476536250c2a0173d4298d15114df7a89:

perf trace: Remove redundant ')' (2018-04-03 16:16:41 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
- Show only failing syscalls with 'perf trace --failure' (Arnaldo Carvalho de Melo)
e.g: See what 'openat' syscalls are failing:
# perf trace --failure -e openat
762.323 ( 0.007 ms): VideoCapture/4566 openat(dfd: CWD, filename: /dev/video2) = -1 ENOENT No such file or directory
<SNIP N /dev/videoN open attempts... sigh, where is that improvised camera lid?!? 8-) >
790.228 ( 0.008 ms): VideoCapture/4566 openat(dfd: CWD, filename: /dev/video63) = -1 ENOENT No such file or directory
^C#
- Show information about the event (freq, nr_samples, total period/nr_events) in
the annotate --tui and --stdio2 'perf annotate' output, similar to the
first line in the 'perf report --tui', but just for the samples for
the annotated symbol (Arnaldo Carvalho de Melo)
- Introduce 'perf version --build-options' to show what features were
linked, aliased as well as a shorter 'perf -vv' (Jin Yao)
- Add a "dso_size" sort order (Kim Phillips)
- Remove redundant ')' in the tracepoint output in 'perf trace' (Changbin Du)
- Synchronize x86's cpufeatures.h, no effect on tools (Arnaldo Carvalho de Melo)
Signed-off-by: Arnaldo Carvalho de Melo <acme@...hat.com>
----------------------------------------------------------------
Arnaldo Carvalho de Melo (9):
tools headers: Synchronize x86's cpufeatures.h
perf trace: Show only failing syscalls
perf hists browser: Rename perf_evsel_browser_title to a more descriptive name
perf hists: Introduce hists__scnprint_title()
perf hists: Move hists__scnprintf_title() away from the TUI code
perf ui browser: Move the extra title lines from the hists browser
perf annotate: Introduce annotation__scnprintf_samples_period() method
perf annotate browser: Show extra title line with event information
perf annotate stdio2: Print more descriptive event information header
Changbin Du (1):
perf trace: Remove redundant ')'
Jin Yao (5):
perf config: Add some new -DHAVE_XXX to CFLAGS
perf config: Rename to HAVE_DWARF_GETLOCATIONS_SUPPORT
perf version: Print the compiled-in status of libraries
perf tools: Add 'perf -vv' as an alias to 'perf version --build-options'
perf version: Add man page
Jiri Olsa (1):
tools include: Add config.h header file
Kim Phillips (1):
perf tools: Add a "dso_size" sort order

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.
