[PATCH v2] coresight: etm4x: Fix enabling of cycle accurate tracing in perf.

by Mike Leach

Using perf record 'cyclacc' option in cs_etm event was not setting up cycle accurate trace correctly. Corrects bit set in TRCCONFIGR to enable cycle accurate trace. Programs TRCCCCTLR with a valid threshold value as required by ETMv4 spec.

non deterministic records of ETM trace

by Sebastian Pop

Hi, could somebody help me understand why the total size of the recorded ETM trace differs from run to run? Is this something in my Juno machine setup, or do you also see this? The maximum length that has been recorded is about 6MB on my setup. When I am recording the trace of the same program on intel-pt: $ perf record -e intel_pt//u ./sort the amount of captured data is deterministic (around 296MB +/- a few KB.) Thanks, Sebastian sort.c is from https://gcc.gnu.org/wiki/AutoFDO/Tutorial + gcc sort.c -o sort -O3 ++ seq 1 10 + for i in '$(seq 1 10)' + /root/etm/OpenCSD/tools/perf/perf record -e cs_etm/(a)20070000.etr/u --per-thread ./sort Bubble sorting array of 30000 elements 7779 ms [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.610 MB perf.data ] + for i in '$(seq 1 10)' + /root/etm/OpenCSD/tools/perf/perf record -e cs_etm/(a)20070000.etr/u --per-thread ./sort Bubble sorting array of 30000 elements 7789 ms [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.545 MB perf.data ] + for i in '$(seq 1 10)' + /root/etm/OpenCSD/tools/perf/perf record -e cs_etm/(a)20070000.etr/u --per-thread ./sort Bubble sorting array of 30000 elements 7797 ms [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.353 MB perf.data ] + for i in '$(seq 1 10)' + /root/etm/OpenCSD/tools/perf/perf record -e cs_etm/(a)20070000.etr/u --per-thread ./sort Bubble sorting array of 30000 elements 5949 ms [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.353 MB perf.data ] + for i in '$(seq 1 10)' + /root/etm/OpenCSD/tools/perf/perf record -e cs_etm/(a)20070000.etr/u --per-thread ./sort Bubble sorting array of 30000 elements 7807 ms [ perf record: Woken up 2 times to write data ] [ perf record: Captured and wrote 3.287 MB perf.data ] + for i in '$(seq 1 10)' + /root/etm/OpenCSD/tools/perf/perf record -e cs_etm/(a)20070000.etr/u --per-thread ./sort Bubble sorting array of 30000 elements 7772 ms [ perf record: Woken up 3 times to write data ] Warning: AUX data lost 2 times out of 4!

Using perf inject to transform ETM traces into branch events

by Sebastian Pop

Hi Mathieu, perf/Documentation/intel-pt.txt describes how to make autoFDO work with Intel-PT recorded traces: # perf record -e intel_pt//u ./sort # perf inject -i perf.data -o inj --itrace=i100usl --strip # create_gcov --binary=./sort --profile=inj --gcov=sort.gcov -gcov_version=1 # gcc -O3 -fauto-profile=sort.gcov sort.c -o sort_autofdo On the ARM side, I was able to get an ETM trace, and I started working with my colleague Brian Rzycki on the second step that translates the trace into branch events. Attached is the current state of the patch that adds functionality from intel-pt.c to cs-etm.c. We are still trying to get more than one branch recorded in the branch stack before emitting an event, and it looks like what we need is to decode more than a packet at a time in cs-etm-decoder.c like in cs_etm_decoder__buffer_packet() Comments on the early version of the patch are welcome. Thanks, Sebastian
