The main benefit would be to be able to look up memory map from any thread that belongs to the process. This implementes one of the solution ideas for issue described by Don in following thread: http://marc.info/?l=linux-kernel&m=139403876017159&w=2 This patches still has some loose ends, just wanted to hear opinions for this concept. thanks, jirka Signed-off-by: Jiri Olsa Cc: Don Zickus Cc: Corey Ashford Cc: David Ahern Cc: Frederic Weisbecker Cc: Ingo Molnar Cc: Namhyung Kim Cc: Paul Mackerras Cc: Peter Zijlstra Cc: Arnaldo Carvalho de Melo --- Jiri Olsa (5): perf tests: Add tip/pid mmap automated tests perf tools: Factor machine__find_thread to take tid argument perf tools: Allocate thread map_groups dynamicaly perf tools: Add machine pointer into thread struct perf tools: Share process map groups within process threads tools/perf/Makefile.perf | 1 + tools/perf/arch/x86/tests/dwarf-unwind.c | 2 +- tools/perf/perf.h | 6 ++ tools/perf/tests/builtin-test.c | 4 ++ tools/perf/tests/dwarf-unwind.c | 2 +- tools/perf/tests/mmap-events.c | 188 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ tools/perf/tests/tests.h | 1 + tools/perf/ui/stdio/hist.c | 8 ++- tools/perf/util/event.c | 4 +- tools/perf/util/machine.c | 21 ++++--- tools/perf/util/machine.h | 3 +- tools/perf/util/map.h | 3 +- tools/perf/util/thread.c | 87 ++++++++++++++++++++++++++--- tools/perf/util/thread.h | 15 +++-- 14 files changed, 317 insertions(+), 28 deletions(-) create mode 100644 tools/perf/tests/mmap-events.c
