Although functions like vmaCreateBuffer(), vmaCreateImage(), vmaDestroyBuffer(), vmaDestroyImage() create/destroy an allocation and a buffer/image at once, these are just a shortcut for creating the resource, allocating memory, and binding them together. Defragmentation works on memory allocations only. You must handle the rest manually. Defragmentation is an iterative process that should repreat "passes" as long as related functions return VK_INCOMPLETE not VK_SUCCESS. In each pass:

- Mapping an image with layout VK_IMAGE_LAYOUT_DEPTH_STENCIL_ATTACHMENT_OPTIMAL can result in undefined behavior if this memory is used by the device. Only GENERAL or PREINITIALIZED should be used.
- It happens when you map a buffer or image, because the library maps entire VkDeviceMemory block, where different types of images and buffers may end up together, especially on GPUs with unified memory like Intel.

- VMA_ALLOCATION_CREATE_MAPPED_BIT by itself doesn't guarantee that the allocation will end up in a mappable memory type. For this, you need to also specify VMA_ALLOCATION_CREATE_HOST_ACCESS_SEQUENTIAL_WRITE_BIT or VMA_ALLOCATION_CREATE_HOST_ACCESS_RANDOM_BIT. VMA_ALLOCATION_CREATE_MAPPED_BIT only guarantees that if the memory is HOST_VISIBLE, the allocation will be mapped on creation. For an example of how to make use of this fact, see section Advanced data uploading.

Represents custom memory pool.
Note that the structure passed as VmaPoolCreateInfo::pMemoryAllocateNext must remain alive and unchanged for the whole lifetime of the custom pool, because it will be used when the pool allocates a new device memory block. No copy is made internally. This is why variable exportMemAllocInfo is defined as static.
If you want to export all memory allocated by VMA from certain memory types, also dedicated allocations or other allocations made from default pools, an alternative solution is to fill in VmaAllocatorCreateInfo::pTypeExternalMemoryHandleTypes. It should point to an array with VkExternalMemoryHandleTypeFlagsKHR to be automatically passed by the library through VkExportMemoryAllocateInfoKHR on each allocation made from a specific memory type. You should not mix these two methods in a way that allows to apply both to the same memory type. Otherwise, VkExportMemoryAllocateInfoKHR structure would be attached twice to the pNext chain of VkMemoryAllocateInfo.

Represents single memory allocation.
VMA also provides convenience functions that create a buffer or image and bind it to memory represented by an existing VmaAllocation: vmaCreateAliasingBuffer(), vmaCreateAliasingBuffer2(), vmaCreateAliasingImage(), vmaCreateAliasingImage2(). Versions with "2" offer additional parameter allocationLocalOffset.
Remember that using resources that alias in memory requires proper synchronization. You need to issue a memory barrier to make sure commands that use img1 and img2 don't overlap on GPU timeline. You also need to treat a resource after aliasing as uninitialized - containing garbage data. For example, if you use img1 and then want to use img2, you need to issue an image memory barrier for img2 with oldLayout = VK_IMAGE_LAYOUT_UNDEFINED.

Also consider: Consider creating them as dedicated allocations using VMA_ALLOCATION_CREATE_DEDICATED_MEMORY_BIT, especially if they are large or if you plan to destroy and recreate them with different sizes e.g. when display resolution changes. Prefer to create such resources first and all other GPU resources (like textures and vertex buffers) later. When VK_EXT_memory_priority extension is enabled, it is also worth setting high priority to such allocation to decrease chances to be evicted to system memory by the operating system.

That is all. The extension will be automatically used whenever you create a buffer using vmaCreateBuffer() or image using vmaCreateImage().
When using the extension together with Vulkan Validation Layer, you will receive warnings like this:
vkBindBufferMemory(): Binding memory to buffer 0x33 but vkGetBufferMemoryRequirements() has not been called on that buffer.

Although functions like vmaCreateBuffer(), vmaCreateImage(), vmaDestroyBuffer(), vmaDestroyImage() create/destroy an allocation and a buffer/image at once, these are just a shortcut for creating the resource, allocating memory, and binding them together. Defragmentation works on memory allocations only. You must handle the rest manually. Defragmentation is an iterative process that should repreat "passes" as long as related functions return VK_INCOMPLETE not VK_SUCCESS. In each pass:

No copy is made internally. This is why variable exportMemAllocInfo is defined as static.
If you want to export all memory allocated by VMA from certain memory types, also dedicated allocations or other allocations made from default pools, an alternative solution is to fill in VmaAllocatorCreateInfo::pTypeExternalMemoryHandleTypes. It should point to an array with VkExternalMemoryHandleTypeFlagsKHR to be automatically passed by the library through VkExportMemoryAllocateInfoKHR on each allocation made from a specific memory type. You should not mix these two methods in a way that allows to apply both to the same memory type. Otherwise, VkExportMemoryAllocateInfoKHR structure would be attached twice to the pNext chain of VkMemoryAllocateInfo.

Remember that using resources that alias in memory requires proper synchronization. You need to issue a memory barrier to make sure commands that use img1 and img2 don't overlap on GPU timeline. You also need to treat a resource after aliasing as uninitialized - containing garbage data. For example, if you use img1 and then want to use img2, you need to issue an image memory barrier for img2 with oldLayout = VK_IMAGE_LAYOUT_UNDEFINED.
