How about
AMD hardware supports the Slow Memory Bandwidth Allocation (SMBA) feature.
or
AMD hardware supports Slow Memory Bandwidth Allocation (SMBA).

What does "Currently" mean here? If there is a plan for changes, could
that be shared? Otherwise maybe just remove it: "CXL.memory is the only
supported "slow" memory device."

Maybe "is no such device" or "are no such devices"?

"setting the configuring SMBA" is hard to parse. How about just
"configuring SMBA"?
