Subject: [GIT PULL 00/30] perf/urgent fixes
Hi Ingo,
These are fixes that were sitting in perf/core, together with
syncronizing tools/include files with the kernel, to have the build
clean of warnings.
Best regards,
- Arnaldo
Test results at the end of this message, as usual.

perf tools s390: Do not include header files from the kernel sources (2017-11-28 11:27:55 -0300)
----------------------------------------------------------------
perf/urgent fixes:
- Fix window dimensions change handling in 'perf top' (Jiri Olsa)
- Fix 'perf record -c/-F' options for CPU event aliases (Andi Kleen)
- Generate PERF_RECORD_{MMAP,COMM,EXEC} with 'perf record --delay'
fixing symbol resolution for processes created, maps put in place
while --delay happens (Arnaldo Carvalho de Melo)
- Fix up leftover perf_evsel_stat usage via evsel->priv, plugging
a SEGV when using event groups as in:
$ perf stat -e '{cpu-clock,instructions}' workload
- Fix 'perf script --per-event-dump' for auxtrace synth evsels (Arnaldo Carvalho de Melo)
- Ignore kptr_restrict when not sampling the kernel (Arnaldo Carvalho de Melo)
- Synchronize kernel ABI headers wrt SPDX tags and ABI changes,
taking minimal action to handle new syscall args and silencing
perf build warnings (Arnaldo Carvalho de Melo, Ingo Molnar)
- Fix header.size for namespace events (Jiri Olsa)
- Fix a bug during strstart() conversion in 'perf help' (Namhyung Kim)
- Do not truncate instruction names at 6 chars in 'perf annotate', there
are really long instruction names in PPC (Ravi Bangoria)
- Fixup discontiguous/sparse numa nodes in 'perf bench numa' (Satheesh Rajendran)
- Fix an exit code of trace__symbols_init in 'perf trace' (Andrei Vagin)
- Fix 'perf test' entries on s/390 (Thomas Richter)
- Bring instruction decoder files used by Intel PT into line with the kernel,
silencing build warning (Adrian Hunter)
- Fix build on s/390 by not using directly kernel perf_regs.h (Arnaldo Carvalho de Melo)

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.

#
The LLVM test failure is being investigated, looks related to f5caf621ee35
("x86/asm: Fix inline asm call constraints for Clang"), as using tools/perf
built from this perf/urgent branch using headers touched by this cset works
when using sources from just before it (git checkout -b tmp f5caf621ee35^).
The BPF test fails is related to some BPF map artifact, still being
investigated.
