Re:AMD Disables Zen 4's Loop Buffer

The countermeasure is to disable the loop buffer. Everyone who wants to protect themselves from the unknown vulnerability should disable the loop buffer. Once everyone's done that or had a reasonable opportunity to do that, it can be safely published.

There's no real impetus except paranoia if the change is unannounced. You don't have to detail the vulnerability, just inform people that somewhere, one exists, and that this is in fact a countermeasure. Without doing that, you don't shift liability, you don't actually get people out of harm's way, you don't really benefit at all.
