hi, this patchset moves thread's map_groups to be dynamically allocated and shared within process threads.
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 <[email protected]> Cc: Don Zickus <[email protected]> Cc: Corey Ashford <[email protected]> Cc: David Ahern <[email protected]> Cc: Frederic Weisbecker <[email protected]> Cc: Ingo Molnar <[email protected]> Cc: Namhyung Kim <[email protected]> Cc: Paul Mackerras <[email protected]> Cc: Peter Zijlstra <[email protected]> Cc: Arnaldo Carvalho de Melo <[email protected]> --- 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 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
