[Openmp-commits] [PATCH] D141227: [OpenMP][libomptarget] Implement memory lock/unlock API in NextGen plugins

[Jon Chesterfield via Phabricator via Openmp-commits]

JonChesterfield added a comment.

For HSA we can either have coarse grain semantics on a locked pointer or fine grain depending on which hsa calls we make. That surfaces a user visible distinction - if their kernel writes to this memory, can the host see that write while the kernel executes? I don't know which answer is correct but would like us to choose one and document it, and probably have the same behaviour on nvptx.
