Algorithms inside are based on some heuristics that try to maximize number of Vulkan memory blocks to make totally empty to release them, as well as to maximimze continuous empty space inside remaining blocks, while minimizing the number and size of allocations that needs to be moved. Some fragmentation still remains after this call. This is normal.</p>
<p>If you defragment allocations bound to images, these images should be created with <code>VK_IMAGE_CREATE_ALIAS_BIT</code> flag, to make sure that new image created with same parameters and pointing to data copied to another memory region will interpret its contents consistently. Otherwise you may experience corrupted data on some implementations, e.g. due to different pixel swizzling used internally by the graphics driver.</p>
<p>If you defragment allocations bound to images, new images to be bound to new memory region after defragmentation should be created with <code>VK_IMAGE_LAYOUT_PREINITIALIZED</code> and then transitioned to their original layout from before defragmentation using an image memory barrier.</p>

@ -87,7 +87,7 @@ Additional considerations</h1>
<ul>
<li>Replaying file that was recorded on a different GPU (with different parameters like <code>bufferImageGranularity</code>, <code>nonCoherentAtomSize</code>, and especially different set of memory heaps and types) may give different performance and memory usage results, as well as issue some warnings and errors.</li>
<li>Current implementation of recording in VMA, as well as VmaReplay application, is coded and tested only on Windows. Inclusion of recording code is driven by <code>VMA_RECORDING_ENABLED</code> macro. Support for other platforms should be easy to add. Contributions are welcomed.</li>

Use this function instead of old, deprecated vmaDefragment().
It is important to note that between the call to vmaDefragmentationBegin() and
vmaDefragmentationEnd():
- You should not use any of allocations passed as `pInfo->pAllocations`,
including calling vmaGetAllocationInfo(), vmaTouchAllocation(), or accessing
their data.
- Some mutexes protecting internal data structures may be locked, so trying to
make or free any allocations, bind buffers or images, or map memory in between
may cause stall (when done on another thread) or deadlock (when done on the
same thread), unless you are 100% sure that separate memory pools are involved.
- Information returned via `pStats` and `pInfo->pAllocationsChanged` are undefined.
They become valid after call to vmaDefragmentationEnd().
- If `pInfo->commandBuffer != VK_NULL_HANDLE`, you must submit that command buffer
and make sure it finished execution before calling vmaDefragmentationEnd().
