Explicit control over the fastest memory is what GPU local storage or the PlayStation 3 Cell SPUs allow/require.

For x86_64 there are cache hints, no pinning/reserving parts of the caches (as far ad I know).

I wonder if Apple M1 or M2 cpu with unified CPU/GPU memory has anything like pinning or explicit cache control?
