Subject[GIT PULL] perf/core improvements and fixes
Date
Hi Ingo,

Please consider pulling,

Best regards,

- Arnaldo

Test results at the end of this message, as usual.

The following changes since commit 323fd749821daab0f327ec86d707c4542963cdb0:

perf intel-pt: Fix potential NULL pointer dereference found by the smatch tool (2019-07-09 10:13:28 -0300)

are available in the Git repository at:

for you to fetch changes up to 916c31fff946fae0e05862f9b2435fdb29fd5090:

perf version: Fix segfault due to missing OPT_END() (2019-07-15 07:59:05 -0300)

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

perf db-export:

Adrian Hunter:

- Improvements in how COMM details are exported to databases for
post processing and use in the sql-viewer.py UI.

- Export switch events to the database.

BPF:

Arnaldo Carvalho de Melo:

- Bump rlimit(MEMLOCK) for 'perf test bpf' and 'perf trace', just like
selftests/bpf/bpf_rlimit.h do, which makes errors due to exhaustion of
this limit, which are kinda cryptic (EPERM sometimes) less frequent.

perf version:
Ravi Bangoria:

- Fix segfault due to missing OPT_END(), noticed on PowerPC.

perf vendor events:

Thomas Richter:

- Add JSON files for IBM s/390 machine type 8561.

perf cs-etm (ARM):

YueHaibing:

- Fix two cases of error returns not bing done properly: Invalid ERR_PTR() use
and loss of propagation error codes.

Test results:

The first ones are container 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.

The 'perf test bpf' test is about rlimit(MEMLOCK), bump it a to 128K from the
default 64K and it'll work. Next pull req will have auto-adjustment for 'perf
test' and 'perf trace', where BPF programs creating maps are also failing.
