2016-01-15perf build: Test correct path of perf in build-testWang Nan
If an 'O' is passed to 'make build-test', many 'test -x' and 'test -f' will fail because perf resides in a different directory. Fix this by computing PERF_OUT according to 'O' and test correct output files. For make_kernelsrc and make_kernelsrc_tools, set KBUILD_OUTPUT_DIR instead because the path is different from others ($(O)/perf vs $(O)/tools/perf).

2016-01-15perf build: Set parallel making options build-testWang Nan
'make build-test' is painful because of time consuming. In a full test, all test cases are built twice with tools/perf/Makefile and tools/perf/Makefile.perf. 'Makefile' automatically computes parallel options for make, but 'Makefile.perf' not, so all test cases is built with one job. It is very slow. This patch adds '-j' options to Makefile.perf testing. It computes parallel building options like what tools/perf/Makefile does, and pass '-j' option to Makefile.perf test.

2016-01-15perf kvm record/report: 'unprocessable sample' error while ↵Ravi Bangoria
recording/reporting guest data While recording guest samples in host using perf kvm record, it will populate unprocessable sample error, though samples will be recorded properly. While generating report using perf kvm report, no samples will be processed and same error will populate. We have seen this behaviour with upstream perf(4.4-rc3) on x86 and ppc64 hardware. Reason behind this failure is, when it tries to fetch machine from rb_tree of machines, it fails. As a part of tracing a bug, we figured out that this code was incorrectly refactored in commit 54245fdc3576 ("perf session: Remove wrappers to machines__find"). This patch will change the functionality such that if it can't fetch machine in first trial, it will create one node of machine and add that to rb_tree. So next time when it tries to fetch same machine from rb_tree, it won't fail. Actually it was the case before refactoring of code in aforementioned commit. This patch is generated from acme perf/core branch. Below I've mention an example that demonstrate the behaviour before and after applying patch. Before applying patch: [Note: One needs to run guest before recording data in host] ravi@ravi-bangoria:~$ ./perf kvm record -a Warning: 5903 unprocessable samples recorded.

2016-01-11perf test: Fix false TEST_OK result for 'perf test hist'Wang Nan
Commit 71d6de64fedd ("perf test: Fix hist testcases when kptr_restrict is on") solves a double free problem when 'perf test hist' calling setup_fake_machine(). However, the result is still incorrect. For example: $ ./perf test -v 'filtering hist entries' 25: Test filtering hist entries : --- start --- test child forked, pid 4186 Cannot create kernel maps test child finished with 0 ---- end ---- Test filtering hist entries: Ok In this case the body of this test is not get executed at all, but the result is 'Ok'. Actually, in setup_fake_machine() there's no need to create real kernel maps. What we want are the fake maps. This patch removes the machine__create_kernel_maps() in setup_fake_machine(), so it won't be affected by kptr_restrict setting. Test result: $ cat /proc/sys/kernel/kptr_restrict 1 $ ~/perf test -v hist 15: Test matching and linking multiple hists : --- start --- test child forked, pid 24031 test child finished with 0 ---- end ---- Test matching and linking multiple hists: Ok [SNIP] Suggested-and-Acked-by: Namhyung Kim <namhyung@kernel.org> Signed-off-by: Wang Nan <wangnan0@huawei.com> Tested-by: Arnaldo Carvalho de Melo <acme@redhat.com> Cc: Jiri Olsa <jolsa@kernel.org> Cc: Masami Hiramatsu <masami.hiramatsu.pt@hitachi.com> Cc: Zefan Li <lizefan@huawei.com> Cc: pi3orama@163.com Link: http://lkml.kernel.org/r/1452520124-2073-12-git-send-email-wangnan0@huawei.com Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>

2016-01-08perf report: Change default to use event group viewNamhyung Kim
The event group view feature is to see related events together. To use the group view, events should be recorded as a group with a dedicated syntax of surrounding events by braces (-e '{ evt1, evt2, ... }'). Also 'perf report' also requires the --group option to enable it. However it's almost always beneficial to use the group view to see the group events as it's more expressive. And I think it's more natural to see events together if they are recorded as a group. Thus this patch changes the default value to enable it. If users don't want to see like it and keep the original behavior, they can set the report.group config variable to false and/or use --no-group option in the 'perf report' command line.
