+
+// Utility to centralize prefetching decisions.
+//
+// Prefetching needs to strike the balance between the latency savings
+// from upcoming accesses and the excess memory throughput for accesses
+// that are prefetched but are never used.
+//
+// A common access pattern for the object in hot GC code is:
+//   [mark word]   // sometimes, for forwarding pointer accesses
+//   [klass word]  // very often, to discover object type
+//    ...
+//   [oop field N] // often, to traverse the heap or fix references
+//
+// Prefetches work on cache line granularity, so we can pick and choose
+// good static offsets at which to prefetch. It also frees us from
+// polling mark/klass word offsets at runtime.
+//
+// It stands to reason that prefetching at zero is most beneficial.
+// Since it is almost guaranteed to be used by future accesses, there is
+// little downside. For objects that are fully within the cache line,
+// that zero-prefetch also picks up oop fields nicely.
+//
+// Experiments suggest it is also important to handle the case when
+// object crosses the cache line. In this case, zero-prefetch is likely
+// to miss the oop fields cache line. In extreme case, it can prefetch only
+// the mark word, leaving klass word unprefetched. We can prefetch
+// the full next cache line to deal with this case, but it is wasteful,
+// especially on platforms with very large cache lines.
+//
+// Therefore, the second prefetch is done at some small offset to balance
+// the crossing case. If second prefetch hits the same cache line as the
+// first one, there is little downside. This also works automagically with
+// platforms with larger cache line sizes, as both prefetches would converge.
+// If prefetch hits another cache line, it likely means the object crosses
+// the cache line, and that the second prefetch is profitable.
+//
