alt Hacker NewsI was actually pretty far off:
> Unified memory in Linux creates a single address space accessible to both the CPU and GPU, eliminating the need to manually copy data between system RAM and video memory. It is enabled via NVIDIA's CUDA, AMD's ROCm/HIP, or generic kernel-level Heterogeneous Memory Management (HMM).
So it does exist and is available for platforms that matter.
It is interesting how apple claimed that "unified memory" is something special, and ppl believed them.
Intel and AMD had been doing this for years already, and had linux support for it from day 1.
