<p >This algorithm is based on 2-level lists dividing address space into smaller chunks. The first level is aligned to power of two which serves as buckets for requested memory to fall into, and the second level is lineary subdivided into lists of free memory. This algorithm aims to achieve bounded response time even in the worst case scenario. Allocation time can be sometimes slightly longer than compared to other algorithms but in return the application can avoid stalls in case of fragmentation, giving predictable results, suitable for real-time use cases. </p>

<p >Word "pages" is just a suggestion to use this function to allocate pieces of memory needed for sparse binding. It is just a general purpose allocation function able to make multiple allocations at once. It may be internally optimized to be more efficient than calling <a class="el" href="group__group__alloc.html#gabf28077dbf82d0908b8acbe8ee8dd9b8" title="General purpose memory allocation.">vmaAllocateMemory()</a> <code>allocationCount</code> times.</p>
|
|
<p >All allocations are made using same parameters. All of them are created out of the same memory pool and type. If any allocation fails, all allocations already made within this function call are also freed, so that when returned result is not <code>VK_SUCCESS</code>, <code>pAllocation</code> array is always entirely filled with <code>VK_NULL_HANDLE</code>. </p>

<p >This function works by moving allocations to different places (different <code>VkDeviceMemory</code> objects and/or different offsets) in order to optimize memory usage. Only allocations that are in <code>pAllocations</code> array can be moved. All other allocations are considered nonmovable in this call. Basic rules:</p>
|
|
<ul>
|
|
<li>Only allocations made in memory types that have <code>VK_MEMORY_PROPERTY_HOST_VISIBLE_BIT</code> and <code>VK_MEMORY_PROPERTY_HOST_COHERENT_BIT</code> flags can be compacted. You may pass other allocations but it makes no sense - these will never be moved.</li>
|
|
<li>Custom pools created with <a class="el" href="group__group__alloc.html#gga9a7c45f9c863695d98c83fa5ac940fe7a13c8a444197c67866be9cb05599fc726" title="Enables alternative, linear allocation algorithm in this pool.">VMA_POOL_CREATE_LINEAR_ALGORITHM_BIT</a> or <a class="el" href="group__group__alloc.html#gga9a7c45f9c863695d98c83fa5ac940fe7a97a0dc38e5161b780594d998d313d35e" title="Enables alternative, buddy allocation algorithm in this pool.">VMA_POOL_CREATE_BUDDY_ALGORITHM_BIT</a> flag are not defragmented. Allocations passed to this function that come from such pools are ignored.</li>
|
|
<li>Allocations created with <a class="el" href="group__group__alloc.html#ggad9889c10c798b040d59c92f257cae597a3fc311d855c2ff53f1090ef5c722b38f" title="Set this flag if the allocation should have its own memory block.">VMA_ALLOCATION_CREATE_DEDICATED_MEMORY_BIT</a> or created as dedicated allocations for any other reason are also ignored.</li>
|
|
<li>Both allocations made with or without <a class="el" href="group__group__alloc.html#ggad9889c10c798b040d59c92f257cae597a11da372cc3a82931c5e5d6146cd9dd1f" title="Set this flag to use a memory that will be persistently mapped and retrieve pointer to it.">VMA_ALLOCATION_CREATE_MAPPED_BIT</a> flag can be compacted. If not persistently mapped, memory will be mapped temporarily inside this function if needed.</li>
|
|
<li>You must not pass same <a class="el" href="struct_vma_allocation.html" title="Represents single memory allocation.">VmaAllocation</a> object multiple times in <code>pAllocations</code> array.</li>
|
|
</ul>
|
|
<p >The function also frees empty <code>VkDeviceMemory</code> blocks.</p>
|
|
<p >Warning: This function may be time-consuming, so you shouldn't call it too often (like after every resource creation/destruction). You can call it on special occasions (like when reloading a game level or when you just destroyed a lot of objects). Calling it every frame may be OK, but you should measure that on your platform.</p>

|
|
<li>Some mutexes protecting internal data structures may be locked, so trying to make or free any allocations, bind buffers or images, map memory, or launch another simultaneous defragmentation in between may cause stall (when done on another thread) or deadlock (when done on the same thread), unless you are 100% sure that defragmented allocations are in different pools.</li>
