Intel instead would argue that the pre-KPTI implementation is a performance feature and does not guarantee security, and that SW should use a KPTI like implementation if security is to be improved.

If there is some intel documentation stating that it is guaranteed to be secure, then yes a lawsuit would have potential. If anything it's the SW vendor that you sue, they are creating the performance degradation. Re: When do the lawsuits begin ? Class actions. It also made it less likely to be implemented correctly and less likely to be properly tested. It didn't need to do OoO but having it OoO made it shinier. If people's systems can't cope without speculative/OoO execution, perhaps people might want to look into the benefits of older simpler software, that wasn't so bloated with shininess as to need the joys of inadequately tested processors underneath.Īny experts on 'product liability' laws care to comment here? It would seem unfortunate if the manufacturer of the defective products is the one who ultimately benefits because their customers have to pay again for hardware that wasn't fit for purpose when sold, because it wasn't properly architected, wasn't properly implemented, wasn't properly tested.Īnd yes I have worked with a team validating an out-of-order microprocessor implemetation. I think based on information to date that people *might* want to be asking about 'lead time on OLD CPUs' (ie ones that don't have speculative/out of order execution).
