Summary: Traffic manager validation tests fail on a 32-bit x86
host
Product: OpenDataPlane - linux- generic reference
Version: v1.10

OS: Linux
Status: UNCONFIRMED

Traffic manager validation tests fail on a 32-bit x86 host (Ubuntu 16.04).
Output from the first failing validation test:
Test: traffic_mngr_test_shaper ...Sent 50 packets
tm_process_expired_timers bad timer return
traffic_mngr.c:2382:test_shaper_bw():Sent 50 pkts but only 2 came back
traffic_mngr.c:2382:test_shaper_bw():Sent 50 pkts but only 0 came back
traffic_mngr.c:2382:test_shaper_bw():Sent 50 pkts but only 0 came back
traffic_mngr.c:2382:test_shaper_bw():Sent 50 pkts but only 0 came back
tm_process_expired_timers bad timer return

FAILED
1. traffic_mngr.c:3666 - test_shaper_bw("bw1", "node_1_1_1", 0, 1 * MBPS)
== 0
2. traffic_mngr.c:3667 - test_shaper_bw("bw4", "node_1_1_1", 1, 4 * MBPS)
== 0
3. traffic_mngr.c:3668 - test_shaper_bw("bw10", "node_1_1_1", 2, 10 *
MBPS) == 0
4. traffic_mngr.c:3669 - test_shaper_bw("bw40", "node_1_1_1", 3, 40 *
MBPS) == 0
5. traffic_mngr.c:3670 - test_shaper_bw("bw100", "node_1_1_2", 0, 100 *
MBPS) == 0
It seems that at least here (odp_traffic_mngr.c) the code assumes 64-bit
pointers:
2156: timer_context = (uint64_t)(uintptr_t)ptr;
2157: queue_num = (timer_context & 0xFFFFFFFF) >> 4;
2158: timer_seq = timer_context >> 32;
2159: tm_queue_obj = tm_system->queue_num_tbl[queue_num];
