The linux-generic implements timers supposing that timers are based on CPU cycle counter. It's not always true and timer API can have nothing common with CPU cycles. Thus timer test shouldn't print here conversion cycles/ns table for time API.
Signed-off-by: Ivan Khoronzhuk <ivan.khoronz...@linaro.org> --- I'm not sure about moving the table to validation test, but it can be useful to visually see resolution impact. This patch should be included in "odp-lng] [Patch 0/4] preparation series before updating odp time API" https://lists.linaro.org/pipermail/lng-odp/2015-August/014850.html But before let's clarify it. example/timer/odp_timer_test.c | 21 --------------------- test/validation/time/time.c | 21 ++++++++++++++++++++- 2 files changed, 20 insertions(+), 22 deletions(-) diff --git a/example/timer/odp_timer_test.c b/example/timer/odp_timer_test.c index 49630b0..6248939 100644 --- a/example/timer/odp_timer_test.c +++ b/example/timer/odp_timer_test.c @@ -322,7 +322,6 @@ int main(int argc, char *argv[]) odph_linux_pthread_t thread_tbl[MAX_WORKERS]; int num_workers; odp_queue_t queue; - uint64_t cycles, ns; odp_queue_param_t param; odp_pool_param_t params; odp_timer_pool_param_t tparams; @@ -446,26 +445,6 @@ int main(int argc, char *argv[]) return -1; } - printf("CPU freq %"PRIu64" Hz\n", odp_sys_cpu_hz()); - printf("Cycles vs nanoseconds:\n"); - ns = 0; - cycles = odp_time_ns_to_cycles(ns); - - printf(" %12"PRIu64" ns -> %12"PRIu64" cycles\n", ns, cycles); - printf(" %12"PRIu64" cycles -> %12"PRIu64" ns\n", cycles, - odp_time_cycles_to_ns(cycles)); - - for (ns = 1; ns <= 100*ODP_TIME_SEC; ns *= 10) { - cycles = odp_time_ns_to_cycles(ns); - - printf(" %12"PRIu64" ns -> %12"PRIu64" cycles\n", ns, - cycles); - printf(" %12"PRIu64" cycles -> %12"PRIu64" ns\n", cycles, - odp_time_cycles_to_ns(cycles)); - } - - printf("\n"); - gbls->num_workers = num_workers; /* Initialize number of timeouts to receive */ diff --git a/test/validation/time/time.c b/test/validation/time/time.c index 4b81c2c..ae5e77c 100644 --- a/test/validation/time/time.c +++ b/test/validation/time/time.c @@ -45,7 +45,7 @@ void time_test_odp_cycles_negative_diff(void) /* check that related conversions come back to the same value */ void time_test_odp_time_conversion(void) { - uint64_t ns1, ns2, cycles; + uint64_t ns, ns1, ns2, cycles; uint64_t upper_limit, lower_limit; ns1 = 100; @@ -59,6 +59,25 @@ void time_test_odp_time_conversion(void) upper_limit = ns1 + TOLERANCE; lower_limit = ns1 - TOLERANCE; CU_ASSERT((ns2 <= upper_limit) && (ns2 >= lower_limit)); + + printf("Cycles vs nanoseconds:\n"); + ns = 0; + cycles = odp_time_ns_to_cycles(ns); + + printf(" %12" PRIu64 " ns -> %12" PRIu64 " cycles\n", ns, cycles); + printf(" %12" PRIu64 " cycles -> %12" PRIu64 " ns\n", cycles, + odp_time_cycles_to_ns(cycles)); + + for (ns = 1; ns <= 100 * ODP_TIME_SEC; ns *= 10) { + cycles = odp_time_ns_to_cycles(ns); + + printf(" %12" PRIu64 " ns -> %12" PRIu64 " cycles\n", ns, + cycles); + printf(" %12" PRIu64 " cycles -> %12" PRIu64 " ns\n", cycles, + odp_time_cycles_to_ns(cycles)); + } + + printf("\n"); } CU_TestInfo time_suite_time[] = { -- 1.9.1 _______________________________________________ lng-odp mailing list lng-odp@lists.linaro.org https://lists.linaro.org/mailman/listinfo/lng-odp
