Summary: - During repeating ostest with sabre-6quad:smp (QEMU), I noticed that pthread_rwlock_test sometimes stops - Finally, I found that nxtask_exit() released a critical section too early before context switching which resulted in selecting inappropriate TCB - This commit fixes this issue by moving nxsched_resume_scheduler() from nxtask_exit() to up_exit() and also removing spin_setbit() and spin_clrbit() from nxtask_exit() because the caller holds a critical section - To be consistent with non-SMP cases, the above changes were done for all CPU architectures Impact: - This commit affects all CPU architectures regardless of SMP Testing: - Tested with ostest with the following configs - sabre-6quad:smp (QEMU, dev board), sabre-6quad:nsh (QEMU) - spresense:wifi_smp - sim:smp, sim:ostest - maix-bit:smp (QEMU) - esp32-devkitc:smp (QEMU) - lc823450-xgevk:rndis Signed-off-by: Masayuki Ishikawa <Masayuki.Ishikawa@jp.sony.com> |
