Hello, Frederick, all, TREE04 and TREE07 still fail on the 5.15 kernel. The stutter patches helped 5.10, 6.1 and 6.4 but 5.15 still is troubled. Any thoughts? OTOH, I am not sure how many NO_HZ_FULL users are on the 5.15 kernel. Do you have any idea? Meanwhile I'll continue to debug it. Thank you! --- Mon Aug 7 07:37:10 AM UTC 2023 Test summary: Results directory: /usr/local/google/home/joelaf/.jenkins/workspace/rcutorture_stable_linux-5.15.y/tools/testing/selftests/rcutorture/res/2023.08.07-04.01.19 tools/testing/selftests/rcutorture/bin/kvm.sh --cpus 48 --duration 60 RUDE01 ------- 22984 GPs (6.38444/s) [tasks-rude: g0 f0x0 total-gps=0] SRCU-N ------- 318544 GPs (88.4844/s) [srcu: g4127136 f0x0 total-gps=4127136] SRCU-P ------- 268977 GPs (74.7158/s) [srcud: g2180244 f0x0 total-gps=2180244] SRCU-T ------- 497422 GPs (138.173/s) [srcu: g57760 f0x0 total-gps=57760] SRCU-U ------- 1152598 GPs (320.166/s) [srcud: g33534 f0x0 total-gps=33534] TASKS01 ------- 11516 GPs (3.19889/s) [tasks: g0 f0x0 total-gps=0] TASKS02 ------- 13407 GPs (3.72417/s) [tasks: g0 f0x0 total-gps=0] TASKS03 ------- 4598 GPs (1.27722/s) [tasks: g0 f0x0 total-gps=0] TINY01 ------- 422041 GPs (117.234/s) [rcu: g0 f0x0 total-gps=0] n_max_cbs: 77229 TINY02 ------- 441676 GPs (122.688/s) [rcu: g0 f0x0 total-gps=0] n_max_cbs: 10691 TRACE01 ------- 12593 GPs (3.49806/s) [tasks-tracing: g0 f0x0 total-gps=0] TRACE02 ------- 106606 GPs (29.6128/s) [tasks-tracing: g0 f0x0 total-gps=0] TREE01 ------- 42614 GPs (11.8372/s) [rcu: g346169 f0x0 total-gps=86809] TREE02 ------- 161421 GPs (44.8392/s) [rcu: g1356445 f0x0 total-gps=339371] n_max_cbs: 177936 TREE03 ------- 105074 GPs (29.1872/s) [rcu: g1699381 f0x2 total-gps=425089] n_max_cbs: 631295 TREE04 ------- 106036 GPs (29.4544/s) n_max_cbs: 550875 QEMU killed TREE04 no success message, 222 successful version messages !!!
