+; Each compute unit has it's own L1 cache. The L2 cache is shared between

+; L1.  The L1 cache can be flushed and invalidated using instructions.
+;
+; Therefore, in order for "acquire" and "release" atomic modes to work
+; correctly across compute units we must flush before each "release"
+; and invalidate the cache after each "acquire".  It might seem like
+; invalidation could be safely done before an "acquire", but since each
+; compute unit can run up to 40 threads simultaneously, all reading values
+; into the L1 cache, this is not actually safe.
+;
+; Additionally, scalar flat instructions access L2 via a different cache
+; (the "constant cache"), so they have separate constrol instructions.  We
+; do not attempt to invalidate both caches at once; instead, atomics
+; operating on scalar flat pointers will flush the constant cache, and
+; atomics operating on flat or global pointers will flush L1.  It is up to
+; the programmer to get this right.
