2014-01-31perf tests: No need to set up ref_reloc_symAdrian Hunter1-10/+0
Now that ref_reloc_sym is set up by machine__create_kernel_maps(), the "vmlinux symtab matches kallsyms" test does have to do it.

2014-01-13perf tools: Add test for building detached source tarballsArnaldo Carvalho de Melo2-2/+29
Test one of the main kernel Makefile targets to generate a perf sources tarball suitable for build outside the full kernel sources. This is to test that the tools/perf/MANIFEST file lists all the files needed to be in such tarball, which sometimes gets broken when we move files around, like when we made some files that were in tools/perf/ available to other tools/ codebases by moving it to tools/include/, etc. Now everytime we use 'make -C tools/perf -f tests/make' this test will be performed, helping detect such problems earlier in the devel cycle.

2013-11-11perf evsel: Remove idx parm from constructorArnaldo Carvalho de Melo6-7/+7
Most uses of the evsel constructor are followed by a call to perf_evlist__add with an idex of evlist->nr_entries, so make rename the current constructor to perf_evsel__new_idx and remove the need for passing the constructor for the common case. We still need the new_idx variant because the way groups are handled, with evsel->nr_members holding the number of entries in an evlist, partitioning the evlist into sublists inside a single linked list. This asks for a clarifying refactoring, but for now simplify the non parser cases, so that tool writers don't have to bother with evsel idx setting.

In fact the "sample parsing" test does not automatically check new sample type bits - they must be added to the comparison logic. Doing that shows that the test fails because the functions perf_event__synthesize_sample() and perf_event__sample_event_size() have not been updated with PERF_SAMPLE_TRANSACTION either.

2013-11-04perf tools: Add time argument on COMM settingFrederic Weisbecker2-3/+3
This way we can later delimit a lifecycle for the COMM and map a hist to a precise COMM:timeslice couple. PERF_RECORD_COMM and PERF_RECORD_FORK events that don't have PERF_SAMPLE_TIME samples can only send 0 value as a timestamp and thus should overwrite any previous COMM on a given thread because there is no sensible way to keep track of all the comms lifecycles in a thread without time informations.

2013-11-01perf test: Update command line callchain attribute testsArnaldo Carvalho de Melo4-6/+6
The "struct perf_event_attr setup" entry in 'perf test' is in fact a series of tests that will exec the tools, passing different sets of command line arguments to then intercept the sys_perf_event_open syscall, in user space, to check that the perf_event_attr->sample_type and other feature request bits are setup as expected. We recently restored the callchain requesting command line argument, -g, to not require a parameter ("dwarf" or "fp"), instead using a default ("fp" for now) and making the long option variant, --call-chain, be the one to be used when a different callchain collection method is preferred. The "struct perf_event_attr setup" test failed because we forgot to update the tests involving callchains, not switching from, '-g dwarf' to '--call-chain dwarf', making 'perf test' detect it: [root@sandy ~]# perf test -v 13 13: struct perf_event_attr setup : --- start --- running '/home/acme/libexec/perf-core/tests/attr/test-record-basic' running '/home/acme/libexec/perf-core/tests/attr/test-record-branch-any' <SNIP> running '/home/acme/libexec/perf-core/tests/attr/test-record-graph-default' running '/home/acme/libexec/perf-core/tests/attr/test-record-graph-dwarf' expected sample_type=12583, got 295 expected exclude_callchain_user=1, got 0 expected sample_stack_user=8192, got 0 FAILED '/home/acme/libexec/perf-core/tests/attr/test-record-graph-dwarf' - match failure ---- end ---- struct perf_event_attr setup: FAILED! [root@sandy ~]# Fix all of them now to use --call-chain when explicitely specifying a method. There is still work to do, as '-g fp', for instance, passed without problems. In that case 'perf test' saw no problems as the intercepted syscall got the bits as expected, i.e. the default is 'fp', but the fact that 'fp' may be an existing program and the specified workload would then be passed as a parameter to it is an usability problem that needs fixing.
