perf tests: Add dwarf unwind test on ARM

2014-05-16T09:39:18+00:00

Adding dwarf unwind test, that setups live machine data over
the perf test thread and does the remote unwind.

Need to use -fno-optimize-sibling-calls for test compilation,
otherwise 'krava_*' function calls are optimized into jumps
and omitted from the stack unwind.

So far it was enabled only for x86.

perf tests: Add thread maps lookup automated tests

2014-04-28T11:42:52+00:00

Adding automated test for memory maps lookup within multiple machines
threads.

The test creates 4 threads and separated memory maps. It checks that we
could use thread__find_addr_map function with thread object based on TID
to find memory maps.

perf tests: Add a test case for hists filtering

2014-04-28T11:42:45+00:00

Now we have changed how hists stats are accounted especially when
filter(s) applied.  So add a test case to verify it.

perf callchain: Introduce HAVE_DWARF_UNWIND_SUPPORT macro

2014-02-18T12:34:48+00:00

Introducing global macro HAVE_DWARF_UNWIND_SUPPORT to indicate we have
dwarf unwind support. Any library providing the dwarf post unwind
support will enable this macro.

perf tests x86: Add dwarf unwind test

2014-02-18T12:34:47+00:00

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.
