Summary: Some architectures, in this case powerpc64, need explicit synchronization barriers vs device accesses. Prior to this change, when running 'make buildworld -j72' on a 18-core (72-thread) POWER9, I would see controller resets often. With this change, I don't see these resets messages, though another tester still does, for yet to be determined reasons, so this may not be a complete fix. Additionally, I see a ~5-10% speed up in buildworld times, likely due to not needing to reset the controller. Reviewed By: jimharris Differential Revision: https://reviews.freebsd.org/D16570 |
