Correct. Probably the only way to mitigate interrupt stuff today is what they mentioned - you inject noise into the system intentionally with their example being to make network requests to local addresses. Fundamentally though the challenge is that if you start doing that, you probably start degrading performance fairly quickly for your neighbors. It’s really hard to balance mitigations that retain good performance. A more comprehensive solution probably involves a redesign of how we build CPUs and operating systems rather than trying to keep fighting this in software.

Let me correct something I stated. To get this correct you still need a timer which you can inject noise into to screw up measurements in theory.
