E.g normal System Memory, Persistent Memory. To understand how the workload maps to those memories, it's important to know the I/O statistics of them. Perf can collect physical addresses, but those are raw data. It still needs extra work to resolve the physical addresses. Provide a script to facilitate the physical addresses resolving and I/O statistics. Profile with MEM_INST_RETIRED.ALL_LOADS or MEM_UOPS_RETIRED.ALL_LOADS event if any of them is available. Look up the /proc/iomem and resolve the physical address. Provide memory type summary. Here is an example output: # perf script report mem-phys-addr Event: mem_inst_retired.all_loads:P Memory type count percentage ---------------------------------------- ----------- ----------- System RAM 74 53.2% Persistent Memory 55 39.6% N/A --- Changes since V2: - Apply the new license rules. - Add comments for globals Changes since V1: - Do not mix DLA and Load Latency. Do not compare the loads and stores. Only profile the loads. - Use event name to replace the RAW event Signed-off-by: Kan Liang Reviewed-by: Andi Kleen Cc: Dan Williams Cc: Jiri Olsa Cc: Peter Zijlstra Cc: Philippe Ombredanne Cc: Stephane Eranian Link: https://lkml.kernel.org/r/1515099595-34770-1-git-send-email-kan.liang@intel.com Signed-off-by: Arnaldo Carvalho de Melo --- tools/perf/util/scripting-engines/trace-event-python.c | 2 ++ 1 file changed, 2 insertions(+) (limited to 'tools/perf/util/scripting-engines/trace-event-python.c') diff --git a/tools/perf/util/scripting-engines/trace-event-python.c b/tools/perf/util/scripting-engines/trace-event-python.c index c1848b543f27..ea070883c593 100644 --- a/tools/perf/util/scripting-engines/trace-event-python.c +++ b/tools/perf/util/scripting-engines/trace-event-python.c @@ -499,6 +499,8 @@ static PyObject *get_perf_sample_dict(struct perf_sample *sample, PyLong_FromUnsignedLongLong(sample->time)); pydict_set_item_string_decref(dict_sample, "period", PyLong_FromUnsignedLongLong(sample->period)); + pydict_set_item_string_decref(dict_sample, "phys_addr", + PyLong_FromUnsignedLongLong(sample->phys_addr)); set_sample_read_in_dict(dict_sample, sample, evsel); pydict_set_item_string_decref(dict, "sample", dict_sample); -- cgit
