I’m not sure what part is confusing you or how to word it another way to make more sense to you.

What I’m saying is that instead of using the secret AMX instructions, just use SME , assuming they have the hardware available to them.

AMX isn’t truly gone afaik , at least according to the folks who have been looking at it. It’s just deprecated and it seems like the architecture treats them somewhat like aliases, preventing concurrent use within a process.
