As suggested by @AGSaidi in issue #958, on ARMv8 its convenient to use an "isb" instruction in pl_cpu_relax() to improve fairness. Without it I've met a few watchdog conditions on valid locks with 16 threads, indicating that some threads couldn't manage to get it in 2 seconds. I never happened again with it. In addition, the performance increased by slightly more than 5% thanks to the reduced contention. This should be backported as far as 2.2, possibly even 2.0. |
