hi, this patchset adds data behind the [vdso] map as a special DSO. This is helpful for dwarf unwind, because now we can unwind samples taken from [vdso] map. Example output is given in patch 4/4.
Patch 1/1 fixies separate issue. Attached patches: 1/4 perf tools: Do backtrace post unwind only if we regs and stack were captured 2/4 perf tools: Add memdup function 3/4 perf dso: Make dsos__find function globally available 4/4 perf tools: Back [vdso] DSO with real data thanks, jirka Cc: Arnaldo Carvalho de Melo <[email protected]> Cc: Peter Zijlstra <[email protected]> Cc: Ingo Molnar <[email protected]> Cc: Paul Mackerras <[email protected]> Cc: Frederic Weisbecker <[email protected]> --- tools/perf/Makefile | 2 ++ tools/perf/builtin-buildid-cache.c | 3 ++- tools/perf/util/header.c | 70 +++++++++++++++++++++++++++++++++++++++----------------- tools/perf/util/header.h | 2 +- tools/perf/util/include/linux/string.h | 2 ++ tools/perf/util/map.c | 12 +++++++--- tools/perf/util/session.c | 7 ++++++ tools/perf/util/string.c | 18 ++++++++++++++- tools/perf/util/symbol.c | 2 +- tools/perf/util/symbol.h | 1 + tools/perf/util/vdso.c | 111 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ tools/perf/util/vdso.h | 18 +++++++++++++++ 12 files changed, 220 insertions(+), 28 deletions(-) -- 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/
