Is this a "bug" we can recover from (in future hardware or software) or are we going to collectively take a lifetime -18 hit to our Moore's Law progress and lose the gains from this technique forever?
- perlgeek 9y agoAt least for Meltdown there are CPU microcode updates out there that should mitigate it, which means the OS level mitigations can be rolled back. And I haven't measured it yet, but I suspect the microcode mitigates are faster. Regarding Spectre, I think it's too early to tell.
- stcredzero 9y agoI'd like a new computer architecture, where communication between different parts of software systems was more explicitly treated as communication. Instead of an exception to pass control to the kernel, how about sending data? Instead of multiple CPU communication through memory (and therefore the cache) how about sending data?
