David has validated the patch and I will send it out soon.\n\nThe test case taking long time to complete happens when the code is compiled with '-O0 -g', but the test case itself completes. The test cases are currently tuned to take less time when compiled with '-O3'.\n\nThanks,\nHonnappa\n\nFrom: David Marchand <david.marchand@redhat.com> \nSent: Friday, May 3, 2019 9:31 AM\nTo: Honnappa Nagarahalli <Honnappa.Nagarahalli@arm.com>\nCc: Ananyev, Konstantin <konstantin.ananyev@intel.com>; Stephen Hemminger <stephen@networkplumber.org>; paulmck@linux.ibm.com; Kovacevic, Marko <marko.kovacevic@intel.com>; dev <dev@dpdk.org>; Gavin Hu (Arm Technology China) <Gavin.Hu@arm.com>; Dharmik Thakkar <Dharmik.Thakkar@arm.com>; Malvika Gupta <Malvika.Gupta@arm.com>; Aaron Conole <aconole@redhat.com>\nSubject: Re: [dpdk-dev] [PATCH v9 2/4] test/rcu_qsbr: add API and functional tests\n\nOn Wed, May 1, 2019 at 5:55 AM Honnappa Nagarahalli <mailto:honnappa.nagarahalli@arm.com> wrote:\nFrom: Dharmik Thakkar <mailto:dharmik.thakkar@arm.com>\n\nAdd API positive/negative test cases, functional tests and\nperformance tests.\n\nSigned-off-by: Malvika Gupta <mailto:malvika.gupta@arm.com>\nSigned-off-by: Dharmik Thakkar <mailto:dharmik.thakkar@arm.com>\nSigned-off-by: Honnappa Nagarahalli <mailto:honnappa.nagarahalli@arm.com>\nReviewed-by: Gavin Hu <mailto:gavin.hu@arm.com>\nAcked-by: Konstantin Ananyev <mailto:konstantin.ananyev@intel.com>\n\nDid not investigate, but this test always fails on my laptop.\nTried multiple times, I caught one instance when the test was still burning cpu after 5 minutes and I killed it.\n\nUsually, it fails like this:\n\n[dmarchan@dmarchan dpdk]$ ./master/app/test -c 0x1f -n 4 --no-huge\nEAL: Detected 8 lcore(s)\nEAL: Detected 1 NUMA nodes\nEAL: Multi-process socket /run/user/114840/dpdk/rte/mp_socket\nEAL: Probing VFIO support...\nEAL: Started without hugepages support, physical addresses not available\nEAL: PCI device 0000:00:1f.6 on NUMA socket -1\nEAL:   Invalid NUMA socket, default to 0\nEAL:   probe driver: 8086:15d7 net_e1000_em\nAPP: HPET is not enabled, using TSC as default timer\nRTE>>rcu_qsbr_perf_autotest \nNumber of cores provided = 4\nPerf test with all reader threads registered\n--------------------------------------------\n\nPerf Test: 3 Readers/1 Writer('wait' in qsbr_check == true)\nTotal RCU updates = 945401635\nCycles per 1000 updates: 25157\nTotal RCU checks = 20000000\nCycles per 1000 checks: 396375\n\nPerf Test: 4 Readers\nTotal RCU updates = 400000000\nCycles per 1000 updates: 6241\n\nPerf test: 4 Writers ('wait' in qsbr_check == false)\nTotal RCU checks = 80000000\nCycles per 1000 checks: 21061\n\nPerf test: 1 writer, 4 readers, 1 QSBR variable, 1 QSBR Query, Blocking QSBR Check\nReader did not complete #28 =  4097\nTest Failed\nRTE>>",
