So I was able to get some info: CLAC/STAC in everything Zen4 and older is
serializing so there's no issue there.
Zen5 is a different story and AC is being renamed there and thus,
non-serializing. So we'd need to do something there, perhaps something
like Josh's patch...
But the good thing is we can alternative it out only for those machines, apart
from the rest.
Thx.
