2014-06-01perf tools: Introduce struct hist_entry_iterNamhyung Kim
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.

2014-05-12perf tools: Use tid for finding threadNamhyung Kim
I believe that passing pid (instead of tid) as the 3rd arg of the machine__find*_thread() was to find a main thread so that it can search proper map group for symbols. However with the map sharing patch applied, it now can do it in any thread. It fixes a bug when each thread has different name, it only reports a main thread for samples in other threads.

2014-04-29perf tests: Add numeric identifier to evlist_testAlexander Yarygin
In tests/parse-events.c test cases are declared in evlist_test[] arrays. 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 tests x86: Add dwarf unwind testJiri Olsa
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.

2014-01-13perf tools: Add test for building detached source tarballsArnaldo Carvalho de Melo
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.

Currently installation tests work only over x86_64, adding arch check to make it work over i386 as well.
