Summary: - I noticed 'pthread_rwlock test' in ostest sometimes stops - This issue happened with spresense:wifi_smp (NCPUS=4) and sim:smp - Finally, I found an issue in pthread_join() - In pthread_join(), sched_lock() is used to avoid pre-emption - However, this is not enough for SMP - Because another CPU would continue the pthread and exit sequences - So we need to protect it with a critical section Impact: - Affect SMP only Testing: - Tested with ostest with the following configurations - spresnese:smp - spresense:wifi_smp (NCPUS=2, NCPUS=4) - sabre-6quad:smp (QEMU) - esp32-core:smp (QEMU) - maix-bit:smp (QEMU) - sim:smp - lc823450-xgevk:rndis Signed-off-by: Masayuki Ishikawa <Masayuki.Ishikawa@jp.sony.com> |
