Hi Ingo/Thomas,

Please consider pulling,

Best regards,

perf parse: Use YYABORT to clear stack after failure, plugging leaks (2019-11-12 08:34:16 -0300)

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

perf record:

Ravi Bangoria:

- Provide an option to print perf_event_open args and syscall return value.
This was already possible using -v, but then lots of other debug info
would be output as well, provide a way to show just the syscall args
and return value, e.g.:

# perf --debug perf-event-open=1 record
perf_event_attr:
size 112
{ sample_period, sample_freq } 4000
sample_type IP|TID|TIME|PERIOD
read_format ID
disabled 1
inherit 1
<SNIP>
ksymbol 1
bpf_event 1
------------------------------------------------------------
sys_perf_event_open: pid 4308 cpu 0 group_fd -1 flags 0x8 = 4

core:

- Remove map->groups, we can get that information in other ways, reduces
the size of a key data structure and paves the way to have it shared
by multiple threads.

- Use 'struct map_symbol' in more places, where we already were using a
'struct map' + 'struct symbol', this helps passing that usual pair of
information across callchain, browser code, etc.

- Add 'struct map_groups' (where the map_symbol->map is) to 'struct map_symbol',
to ease annotation code, for instance, where we call from functions in one map
we're browsing to functions in another DSO, mapped in another 'struct map'.

event parsing:

----------------------------------------------------------------
Arnaldo Carvalho de Melo (13):
perf map: Use map->dso->kernel + map__kmaps() in map__kmaps()
perf symbols: Stop using map->groups, we can use kmaps instead
perf map_groups: Pass the object to map_groups__find_ams()
perf tools: Add map_groups to 'struct addr_location'
perf annotate: Pass a 'map_symbol' in places receiving a pair of 'map' and 'symbol' pointers
perf unwind: Use 'struct map_symbol' in 'struct unwind_entry'
perf callchain: Use 'struct map_symbol' in 'struct callchain_cursor_node'
pref tools: Make 'struct addr_map_symbol' contain 'struct map_symbol'
perf symbols: Use kmaps(map)->machine when we know its a kernel map
perf tools: Add a 'struct map_groups' pointer to 'struct map_symbol'
perf annotate: Stop using map->groups, use map_symbol->mg instead
perf map: Combine maps__fixup_overlappings with its only use
perf map: Remove ->groups from 'struct map'

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.

Clearlinux is failing when building with libpython, but that is not a perf
regression, will try to remove one compiler warning that is causing the problem
when building some of the glue code files in the python files, outside perf.

Manjaro is failing due to some missing library related to bison, looks like
a distro bug.
