Depending on the target platform, some recently published EXT extensions allow sharing memory between different physical devices.
VK_EXT_external_memory_host enables importing host allocations or host-mapped foreign device memory using a host pointer as the handle.
VK_EXT_external_memory_dma_buf enables importing dma_buf handles on Linux which can possibly come from another physical device.
The spec now also has a table where it's listed which external memory handle types require a matching physical device and which don't.
Additionally, I'd also like to draw your attention to additional features which enable execution control across multiple physical devices. At least on Linux (and possibly other POSIX based systems) semaphores and fences can be shared across physical devices if the FENCE_FD and SYNC_FD handle types are used. These are part of the KHR external semaphore/fence extensions.
