Hi All,
A while back I added event support to libpfm and papi for the ARM
Cortex A53 based on the publicly available documentation. However,
I didn't have a means of testing it until recently when I got a
96board dragonboard 410c
(https://www.96boards.org/products/ce/dragonboard410c/) running Ubuntu
15.04 with a custom kernel:
$ uname -a
Linux linaro-alip 4.0.0-linaro-lt-qcom #1 SMP PREEMPT Thu Jun 18 09:43:10 UTC
2015 aarch64 aarch64 aarch64 GNU/Linux
I took a little time to build and run libpfm from libpfm-4.5.0.tar.gz
and the local validate test things loook good:
$ ./validate
Libpfm structure tests:
libpfm ABI version : 0
pfm_pmu_info_t : Passed
pfm_event_info_t : Passed
pfm_event_attr_info_t : Passed
pfm_pmu_encode_arg_t : Passed
pfm_perf_encode_arg_t : Passed
Libpfm internal table tests:
checking perf (80 events): Passed
checking perf_raw (1 events): Passed
Architecture specific tests:
All tests passed
Similarly built papi from the upstream git repository and ran the tests
$ sudo ./run_tests.sh >& papi_git-ac53g.log
Attached are the results of the tests and below are some comments
about the tests.
The cortex a53 doesn't have support for monitoring floating point events so a
number of tests are "SKIPPED" or "PASSED with WARNING":
api.c PASSED with WARNING
Running ctests/calibrate:calibrate.c SKIPPED
Only supported on specific architectures:
Running ctests/data_range:data_range.c SKIPPED
Running ctests/earprofile:earprofile.c SKIPPED
Running ctests/p4_lst_ins:p4_lst_ins.c SKIPPED
Running ctests/zero_smp:zero_smp.c SKIPPED
Missing PAPI_REF_CYC event:
Running ctests/cycle_ratio:cycle_ratio.c SKIPPED
Missing PAPI_L1_TCM event:
Running ctests/tenth:tenth.c SKIPPED
arm using 20MHz for REAL_CYCLES
Running ctests/zero:zero.c FAILED
Don't have openshmem
Running ctests/zero_shmem:zero_shmem.c SKIPPED
Seem to be related to running the run_test.sh with sudo:
Running ctests/exeinfo:exeinfo.c FAILED
Running ctests/profile_pthreads:profile_pthreads.c FAILED
Running ctests/profile_twoevents:profile_twoevents.c FAILED
Looks like need to take a closer look at the domain (kernel/user) control:
Running
components/perf_event/tests/perf_event_system_wide:perf_event_system_wide.c
FAILED
