I think we can worry about that if/when an HCA comes along that supports
global atomics for ordinary atomics but not enhanced atomics. Although
perhaps it would be cleaner to change the atomic_cap enum to:
/*
* IB_ATOMIC_NONE: no atomic capability
* IB_ATOMIC_HCA: all ops are atomic within HCA
* IB_ATOMIC_GLOB: standard ops atomic with respect to all
memory ops; masked ops atomic within HCA
* IB_ATOMIC_GLOB_MASKED: all ops atomic with respect to all
* memory ops
*/
enum ib_atomic_cap {
IB_ATOMIC_NONE,
IB_ATOMIC_HCA,
IB_ATOMIC_GLOB,
IB_ATOMIC_GLOB_MASKED
};
(with better wording for the comments)
Thoughts?
