Hi Ingo,

	Please consider pulling, this is on top of my latest perf/urgent
pull request,

Best regards,

  perf tests: Fix record+probe_libc_inet_pton.sh without ping's debuginfo (2018-09-05 10:47:56 -0300)

----------------------------------------------------------------
perf/core improvements and fixes:

perf trace:

- Augment the payload of syscall entry/exit tracepoints with the contents
  of pointer arguments, such as the "filename" argument to the "open"
  syscall or the 'struct sockaddr *' argument to the 'connect' syscall.

  This is done using a BPF program that gets compiled and attached to
  various syscalls:sys_enter_NAME tracepoints, copying via a BPF map and
  "bpf-output" perf event the raw_syscalls:sys_enter tracepoint payload +
  the contents of pointer arguments using the "probe_read", "probe_read_str"
  and "perf_event_output" BPF functions.

  The 'perf trace' codebase now just processes these augmented tracepoints
  using the existing beautifiers that now check if there is more in the
  perf_sample->raw_data than what is expected for a normal syscall enter
  tracepoint (the common preamble, syscall id, up to six parameters),
  using that with hand crafted struct beautifiers.

  This is just to show how to augment the existing tracepoints, work will
  be done to use DWARF or BTF info to do the pretty-printing and to create
  the collectors.

  For now this is done using an example restricted C BPF program, but the
  end goal is to have this all autogenerated and done transparently.

  Its still useful to have this example as one can use it as an skeleton and
  write more involved filters, see the etcsnoop.c BPF example, for instance.

  E.g.:

  # cd tools/perf/examples/bpf/
  # perf trace -e augmented_syscalls.c ping -c 1 ::1
     0.000 ( 0.008 ms): openat(dfd: CWD, filename: /etc/ld.so.cache, flags: CLOEXEC) = 3

  #

  Use 'perf trace -e augmented_syscalls.c,close ping -c 1 ::1' to see the
  'close' calls as well, as it is not one of the syscalls augmented in that .c
  file.

  (Arnaldo Carvalho de Melo)

- Alias 'umount' to 'umount2' (Benjamin Peterson)

perf stat: (Jiri Olsa)

- Make many builtin-stat.c functions generic, moving display functions
  to a separate file, prep work for adding the ability to store/display
  stat data in perf record/top.

perf annotate: (Kim Phillips)

- Handle arm64 move instructions

perf report: (Thomas Richter):

- Create auxiliary trace data files for s390

libtraceevent: (Tzvetomir Stoyanov (VMware)):

- Split trace-seq related APIs in a separate header file.

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.

Test "x86 bp modify" fails because this is a distro kernel that doesn't have
the underlying kernel feature fixed.
