The major chip manufacturers need to have two kinds of cores/caches. One that has full security guarantees, the other that is optimized for energy efficiency/performance and has zero interprocess security. This isn't a one size fits all problem.
- zzzcpan 9y agoI see some people assume that a possibility of a single chip that can do both is not option. It is. It's only x86 that has to do everything in hardware and hide everything from the user for backwards compatibility. Imagine instructing a compiler for an architecture that does everything in software, like Mill, to make every operation constant time or to speculate aggressively and unsafely depending on what the program needs.
