What I'm not sure about is whether the text should be more explicit in flat out mandating the amdkfd eviction fences for long running compute workloads or workloads where userspace fencing is allowed.
Although (in my humble opinion) it might be possible to completely untangle kernel-introduced fences for resource management and dma-fences used for completion- and dependency tracking and lift a lot of restrictions for the dma-fences, including prohibiting infinite ones, I think this makes sense describing the current state.
