perf tools: Stop fallbacking to kallsyms for vdso symbols lookup (2018-10-17 15:56:15 -0300)
----------------------------------------------------------------
perf/urgent fixes:
- Stop fallbacking to kallsyms for vDSO symbols lookup, this wasn't
being really used and is not valid in arches such as Sparc, where
user and kernel space don't share the address space, relying only on
cpumode to figure out what DSOs to lookup (Arnaldo Carvalho de Melo)
- Align cpu map synthesized events properly, fixing SIGBUS in
CPUs like Sparc (David Miller)
- Fix use of alternatives to find JDIR (Jarod Wilson)
- Store ids for events with their own cpus when synthesizing user
level event details (scale, unit, etc) events, fixing a crash
when recording a PMU event with a cpumask defined (Jiri Olsa)
- Fix wrong filter_band* values for uncore Intel vendor events (Jiri Olsa)
- Fix detection of tracefs path in systems without tracefs, where
that path should be the debugfs mountpoint plus "/tracing/" (Jiri Olsa)
- Pass build flags to traceevent build, allowing using alternative
flags in distro packages, RPM, for instance (Jiri Olsa)
- Fix 'perf report' crash on invalid inline debug information (Milian Wolff)
- Synch kvm uapi copies (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, 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.
This one is being investigatd, doesn't look like its a regression introduced by
this patchset.
