libperf: Fix alignment trap with xyarray contents in 'perf stat' (2019-08-22 17:16:57 -0300)
----------------------------------------------------------------
perf/core improvements and fixes:
perf c2c:
Ravi Bangoria:
- Fix report with offline cpus.
libperf:
Gerald BAEZA:
- Fix alignment trap with xyarray contents in 'perf stat', noticed on ARMv7.
Jiri Olsa:
- Move some more cpu_map and thread_map methods from tools/perf/util/ to libperf.
headers:
Arnaldo Carvalho de Melo:
- Do some house cleaning on the headers, removing needless includes in some places, providing forward declarations when those are the only thing needed, and fixing up the fallout from that for cases where we were using stuff and not adding the necessary headers. Should speed up the build and avoid needless rebuilds when something unrelated gets touched.
----------------------------------------------------------------
Arnaldo Carvalho de Melo (18):
perf arm64: Add missing debug.h header
perf kvm s390: Add missing string.h header
perf metricgroup: Remove needless includes from metricgroup.h perf evsel: Move xyarray.h from evsel.c to evsel.h to reduce include dep tree perf counts: Add missing headers needed for types used
perf bpf: Add missing xyarray.h header
perf evlist: Add missing xyarray.h header
perf script: Add missing counts.h
perf tests: Add missing counts.h
perf stat: Add missing counts.h
perf scripting python: Add missing counts.h header
perf evsel: Add missing perf/evsel.h header in util/evsel.h
perf evsel: Remove needless counts.h header from util/evsel.h perf evsel: Remove needless stddef.h from util/evsel.h
perf evsel: util/evsel.h needs stdio.h as it uses FILE
perf x86 kvm-stat: Add missing string.h header
perf evsel: Switch to libperf's cpumap.h
perf cpumap: Remove needless includes from cpumap.h
Gerald BAEZA (1):
libperf: Fix alignment trap with xyarray contents in 'perf stat'
Jiri Olsa (5):
tools headers: Add missing perf_event.h include
perf tools: Use perf_cpu_map__nr instead of cpu_map__nr
libperf: Move perf's cpu_map__empty() to perf_cpu_map__empty()
libperf: Move perf's cpu_map__idx() to perf_cpu_map__idx()
libperf: Add perf_thread_map__nr/perf_thread_map__pid functions

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.

maintainerPATCH 2/25 perf tools: Use perf_cpu_map__nr instead of cpu_map__nr
In reply to Arnaldo Carvalho de MeloFrom: Jiri Olsa <[email protected]>
Switch the rest of the perf code to use libperf's perf_cpu_map__nr(), which is the same as current cpu_map__nr() and remove the cpu_map__nr() function.

maintainerPATCH 8/25 perf evsel: Move xyarray.h from evsel.c to evsel.h to reduce include dep tree
In reply to Arnaldo Carvalho de MeloFrom: Arnaldo Carvalho de Melo <[email protected]>
All we need in util/evsel.h is the foward declaration of 'struct xyarray', not the internal/xyarray.h, that can be moved to util/evsel.c and then we reduce the header dependency tree.

In reply to Arnaldo Carvalho de MeloFrom: Arnaldo Carvalho de Melo <[email protected]>
Since util/evsel.h uses perf_evsel__cpus() that has its prototype in libperf's perf/evsel.h file, we need it explicitely included.
This was working by luck as util/evsel.h includes counts.h, but that is not necessary, just some forward declarations, so, before we remove counts.h from util/evsel.h, add what is realli needed.

We don't need what is in perf's util/cpumap.h, just the struct cpu_map that is in libperf's internal/cpumap.h file to cover this one case:

So switch to libperf's cpumap.h and add some missing struct foward declarations and include sys/types.h to get pid_t.

maintainerPATCH 24/25 perf c2c: Fix report with offline cpus
In reply to Arnaldo Carvalho de MeloFrom: Ravi Bangoria <[email protected]>
If c2c is recorded on a machine where any cpus are offline, 'perf c2c report' throws an error "node/cpu topology bugFailed setup nodes".
It fails because while preparing node-cpu mapping we don't consider offline cpus.

maintainerPATCH 25/25 libperf: Fix alignment trap with xyarray contents in 'perf stat'
In reply to Arnaldo Carvalho de MeloFrom: Gerald BAEZA <[email protected]>
Following the patch 'perf stat: Fix --no-scale', an alignment trap happens in process_counter_values() on ARMv7 platforms due to the attempt to copy non 64 bits aligned double words (pointed by 'count') via a NEON vectored instruction ('vld1' with 64 bits alignment constraint).
This patch sets a 64 bits alignment constraint on 'contents[]' field in 'struct xyarray' since the 'count' pointer used above points to such a structure.

----------------------------------------------------------------
perf/core improvements and fixes:perf c2c:
Ravi Bangoria:
- Fix report with offline cpus.
libperf:
Gerald BAEZA:
- Fix alignment trap with xyarray contents in 'perf stat', noticed on ARMv7.
Jiri Olsa:
- Move some more
cpu_mapandthread_mapmethods fromtools/perf/util/to libperf.headers:
Arnaldo Carvalho de Melo:
- Do some house cleaning on the headers, removing needless includes in some places, providing forward declarations when those are the only thing needed, and fixing up the fallout from that for cases where we were using stuff and not adding the necessary headers. Should speed up the build and avoid needless rebuilds when something unrelated gets touched.
