Description

In https://github.com/oneapi-src/unified-runtime/pull/525 a number of virtual memory interfaces are added as part of supporting the sycl_ext_oneapi_virtual_mem extension. Discussion on the PR starting here points out concearns that USM and these new virtual memory interfaces are not currently well integrated.

This issue exists to track the discussion about how to meld the USM and Virtual Memory interfaces to interoperate nicely, likley in the adapter implementations, to retain memory tracking capabilities currently available in USM across all memory interfaces.
