Is there an io-fabric in the world which exceeds 1 microsecond to perform a write transaction ?Writes on arm64 aren't usually observable from the remote endpoint when you would expect them to, they can be buffered unless there's an explicit readback right afterwards (which creates a dependency that the processor will fulfill)
I don't mean write-combining cache, I mean posted versus non-posted writes which is a feature of the front-side-bus :)
