perf record: Fix failed memory allocation for get_cpuid_str (2018-01-17 10:31:25 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
- Fix various per event 'max-stack' and 'call-graph=dwarf' issues,
mostly in 'perf trace', allowing to use 'perf trace --call-graph' with
'dwarf' and 'fp' to setup the callgraph details for the syscall events
and make that apply to other events, whilhe allowing to override that on
a per-event basis, using '-e sched:*switch/call-graph=dwarf/' for
instance (Arnaldo Carvalho de Melo)
- Improve the --time percent support in record/report/script (Jin Yao)
- Fix copyfile_offset update of output offset (Jiri Olsa)
- Add python script to profile and resolve physical mem type (Kan Liang)
- Add ARM Statistical Profiling Extensions (SPE) support (Kim Phillips)
- Remove trailing semicolon in the evlist code (Luis de Bethencourt)
- Fix incorrect handling of type _TERM_DRV_CFG (Mathieu Poirier)
- Use asprintf when possible in libtraceevent (Federico Vaga)
- Fix bad force_token escape sequence in libtraceevent (Michael Sartain)
- Add UL suffix to MISSING_EVENTS in libtraceevent (Michael Sartain)
- value of unknown symbolic fields in libtraceevent (Jan Kiszka)
- libtraceevent updates: (Steven Rostedt)
o Show value of flags that have not been parsed
o Simplify pointer print logic and fix %pF
o Handle new pointer processing of bprint strings
o Show contents (in hex) of data of unrecognized type records
o Fix get_field_str() for dynamic strings
- Add missing break in FALSE case of pevent_filter_clear_trivial() (Taeung Song)
- Fix failed memory allocation for get_cpuid_str (Thomas Richter)

----------------------------------------------------------------
Arnaldo Carvalho de Melo (8):

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 ones,
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.
