- xamlhacker 12y agoHSA's requirements are far broader than those provided in Metal. A7's shared memory implementation appears to be far too basic to be able to implement HSA-type API. For example, on-demand paging, user-mode queueing and ability for GPU to do CPU callbacks. Many systems can have shared memory but are not HSA compliant.
