From 98a3b32c99ada4bca8aaf4f91efd96fc906dd5c4 Mon Sep 17 00:00:00 2001 From: Stephane Eranian Date: Thu, 24 Jan 2013 16:10:35 +0100 Subject: perf tools: Add mem access sampling core support This patch adds the sorting and histogram support functions to enable profiling of memory accesses. The following sorting orders are added: - symbol_daddr: data address symbol (or raw address) - dso_daddr: data address shared object - locked: access uses locked transaction - tlb : TLB access - mem : memory level of the access (L1, L2, L3, RAM, ...) - snoop: access snoop mode Signed-off-by: Stephane Eranian Cc: Andi Kleen Cc: Ingo Molnar Cc: Jiri Olsa Cc: Namhyung Kim Cc: Peter Zijlstra Link: http://lkml.kernel.org/r/1359040242-8269-12-git-send-email-eranian@google.com [ committer note: changed to cope with fc5871ed, the move of methods to machine.[ch], and the rename of dsrc to data_src, to match the change made in the PERF_SAMPLE_DSRC in a previous patch. ] Signed-off-by: Arnaldo Carvalho de Melo --- tools/perf/util/session.c | 3 +++ 1 file changed, 3 insertions(+) (limited to 'tools/perf/util/session.c') diff --git a/tools/perf/util/session.c b/tools/perf/util/session.c index 627be09..cf1fe01 100644 --- a/tools/perf/util/session.c +++ b/tools/perf/util/session.c @@ -801,6 +801,9 @@ static void dump_sample(struct perf_evsel *evsel, union perf_event *event, if (sample_type & PERF_SAMPLE_WEIGHT) printf("... weight: %" PRIu64 "\n", sample->weight); + + if (sample_type & PERF_SAMPLE_DATA_SRC) + printf(" . data_src: 0x%"PRIx64"\n", sample->data_src); } static struct machine * -- cgit v1.1
