This past week AMD published a security analysis of AMD Zen 3's new Predictive Store Forwarding (PSF) functionality. In there they did acknowledge there is the possibility where bad PSF functionality could lead to a side-channel attack albeit the real-world exposure would be quite low. In any case they are allowing interested users to disable the Predictive Store Forwarding functionality, but what they didn't comment on in that paper was what performance overhead to expect if disabling PSF. So my Easter weekend turned into AMD Zen 3 PSF benchmarking.

Back in Linux 5.7 the split lock detection landed for warning or even killing the offending software should a split lock occur due to the significant performance impact and possible denial of service. Now it's looking like the bus lock detection code could be ready for mainline...
