Open-Source AMD OpenGL Driver Drops Support For Smart Access Memory / ReBAR

What was removed was experimental optimizations making use of the larger addressable space, not the function in general. The developers saw the feature and thought, "maybe we can use that to do this particular thing differently." Turns out, that thing is slower that way, so they reverted it. This has nothing to do with the larger BAR in general, which can't really slow things down, since it's just removing a small limitation.

So is it being disabled or is code removed? I can't tell anymore. I'd prefer the option to keep it as others have said.

SAM still works just fine. What was removed was one optimization in mesa that didn't end up being a benefit.
