I believe the default scheduling policy is a fair one: # grep SCHED /boot/config-6.1.80-0-sophgo CONFIG_GENERIC_SCHED_CLOCK=y CONFIG_CGROUP_SCHED=y CONFIG_FAIR_GROUP_SCHED=y # CONFIG_RT_GROUP_SCHED is not set CONFIG_SCHED_AUTOGROUP=y # CONFIG_SCHED_MC is not set CONFIG_SCHED_CLUSTER=y # CONFIG_SCHED_SMT is not set CONFIG_SCHED_HRTICK=y CONFIG_MQ_IOSCHED_DEADLINE=m CONFIG_MQ_IOSCHED_KYBER=m CONFIG_IOSCHED_BFQ=m CONFIG_BFQ_GROUP_IOSCHED=y CONFIG_NET_SCHED=y CONFIG_DRM_SCHED=m CONFIG_USB_EHCI_TT_NEWSCHED=y CONFIG_SCHED_INFO=y > > So, you could try to install a different scheduler by default and repeat > the test. It passed with chrt --fifo (I had to do it from outside the LXC container): # time chrt --fifo 10 ./test-pthread-rwlock Starting test_rwlock ... OK real 0m 33.00s user 6m 50.63s sys 0m 16.23s I also verified that it still times out from outside the LXC container with the default: # time ./test-pthread-rwlock Starting test_rwlock ...Command terminated by signal 14 real 10m 0.01s user 1h 46m 24s sys 2m 59.39s # time chrt --rr 10 ./test-pthread-rwlock Starting test_rwlock ... OK real 0m 30.00s user 6m 2.07s sys 0m 19.16s # time chrt --rr 99 ./test-pthread-rwlock Starting test_rwlock ... OK real 0m 30.00s user 6m 9.40s sys 0m 13.37s So even if the CPU cores are slow, they appear to finish in ~30 sec. chrt --other and chrt --idle appears to trigger the deadlock. > > Bruno > > [1]
