perf tools: Fix double free in perf test 21 (code-reading.c)

2014-04-15T11:57:14+00:00

perf_evlist__delete() deletes attached cpu and thread maps
but the test is still using them, so remove them from the
evlist before deleting it.

perf tools: Use tid in mmap/mmap2 events to find maps

2014-03-18T21:17:00+00:00

Now that we can properly synthesize threads system-wide, make sure the
mmap and mmap2 events use tids instead of pids to locate their maps.

perf machine: Factor machine__find_thread to take tid argument

2014-03-14T21:08:42+00:00

Forcing the code to always search thread by pid/tid pair.

The PID value will be needed in future to determine the process thread
leader for map groups sharing.

perf tests: Add pmu-bison.o make test

2014-02-24T12:29:35+00:00

Adding pmu-bison.o make test:

  $ make -f tests/make make_util_pmu_bison_o
  - make_util_pmu_bison_o: cd . && make -f Makefile DESTDIR=/tmp/tmp.0u99hQn8Ga util/pmu-bison.o
  $ make -f tests/make make_util_pmu_bison_o_O
  - make_util_pmu_bison_o_O: cd . && make -f Makefile O=/tmp/tmp.sWKDLGS71O DESTDIR=/tmp/tmp.htQNJAfJ0d util/pmu-bison.o
  make: *** [make_util_pmu_bison_o_O] Error 1

The 'O=' version of the test is failing at the moment, due to the OUTPUT
directory issue fixed in next patch.

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 callchain: Add mask into struct regs_dump

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

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.

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.
