Description

Vulkan apps may wish to export or import device memory handles to or from other logical devices, instances, or APIs.

This memory sharing can eliminate copies of memory buffers when different subsystems need to interoperate on them. Sharing memory buffers may also facilitate a better distribution of processing workload for more complex memory manipulation pipelines.

New Commands

New Structures

New Enum Constants

Issues
