I'm not sure these patches were motivated by Android (based on x86 focus in the commit message), but Davidlohr would have to comment on that. That's just where most of my experience comes from and what I can share details about.
This series was motivated by exploring new use cases for dma-buf (such as kvcache), not really for Android specifically. I was counting on the cheap/one-time 2Mb attempt (current high order semantics) to not be a problem for potential performance gains. As for the x86 I tested here, basically because it's what I have on hand, I had no idea ROCm was a no-no for system heaps. I am fine dropping this effort. Thanks, Davidlohr
