[Openmp-commits] [PATCH] D142514: [OpenMP][libomptarget] Notify the plugins regarding new mapping/unmappings

[Kevin Sala via Phabricator via Openmp-commits]

kevinsala added a comment.

The locking of mapped host buffers is disabled by default. Can be enabled through the `LIBOMPTARGET_LOCK_MAPPED_HOST_BUFFERS` envar. The envar accepts boolean values (on/off) and a special option:

- `off`:  Do not lock mapped host buffers (default).
- `on`:  Lock mapped host buffers automatically, but do not report lock failures if the plugin fails to lock them.
- `mandatory`: Lock mapped host buffers automatically and treat locking failures in the plugins as fatal errors. This option may be useful for debugging purposes.
