2014-07-18perf tools: Enable close-on-exec flag on perf file descriptorYann Droneaud3-3/+9
In commit a21b0b354d4a ('perf: Introduce a flag to enable close-on-exec in perf_event_open()'), flag PERF_FLAG_FD_CLOEXEC was added to perf_event_open(2) syscall to allows userspace to atomically enable close-on-exec behavor when creating the file descriptor. This patch makes perf tools use the new flag if supported by the kernel, so that the event file descriptors got automatically closed if perf tool exec a sub-command.

There're some duplicate code when adding hist entries. They are different in that some have branch info or mem info but generally do same thing. So introduce new struct hist_entry_iter and add callbacks to customize each case in general way. The new perf_evsel__add_entry() function will look like: iter->prepare_entry(); iter->add_single_entry(); while (iter->next_entry()) iter->add_next_entry(); iter->finish_entry(); This will help further work like the cumulative callchain patchset.

2014-04-29perf tests: Add numeric identifier to evlist_testAlexander Yarygin1-45/+90

Elements of arrays are initialized in following pattern: [i] = { .name = ..., .check = ..., }, When perf-test is running with '-v' option, 'i' variable will be printed for every existing test. However, we can't add any arch specific tests inside #ifdefs, because it will create collision between the element number inside #ifdef and the next one outside. This patch adds 'id' field in evlist_test, uses it as a test identifier and removes explicit numbering of array elements. This helps to number tests with gaps.

2014-02-18perf callchain: Add mask into struct regs_dumpJiri Olsa2-10/+9
Adding mask info into struct regs_dump to make the registers information compact. The mask was always passed along, so logically the mask info fits more into the struct regs_dump.

2014-02-18perf tests x86: Add dwarf unwind testJiri Olsa3-0/+161
Adding dwarf unwind test, that setups live machine data over the perf test thread and does the remote unwind. At this moment this test fails due to bug in the max_stack processing in unwind__get_entries function. This is fixed in following patch. Need to use -fno-optimize-sibling-calls for test compilation, otherwise 'krava_*' function calls are optimized into jumps and ommited from the stack unwind. So far it's enabled only for x86.

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.

2014-01-14perf record: Rename --no-delay to --no-bufferingArnaldo Carvalho de Melo2-7/+7
That is how the option summary describes it and so that we can free --delay to replace --initial-delay and then be consistent with stat's --delay equivalent option.

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.

2014-01-13perf evlist: Introduce evlist__for_each() & friendsArnaldo Carvalho de Melo4-6/+6
For the common evsel list traversal, so that it becomes more compact. Use the opportunity to start ditching the 'perf_' from 'perf_evlist__', as discussed, as the whole conversion touches a lot of places, lets do it piecemeal when we have the chance due to other work, like in this case.

2014-01-13perf tests: Fix installation tests path setupJiri Olsa1-10/+20
Currently installation tests work only over x86_64, adding arch check to make it work over i386 as well. NOTE looks like x86 is the only arch running tests, we need some IS_(32/64) flag to make this generic.
