">vmaAllocateMemory()</a>, exact type of such allocations is not known, so allocator must be conservative in handling Buffer-Image Granularity, which can lead to suboptimal allocation (wasted memory). In that case, if you can make sure you always allocate only buffers and linear images or only optimal images out of this pool, use this flag to make allocator disregard Buffer-Image Granularity and so make allocations more optimal. </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 pAllocations 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> flag can be compacted. You may pass other allocations but it makes no sense - these will never be moved.</li>
|
|
<li>You may pass allocations made with <a class="el" href="vk__mem__alloc_8h.html#ad9889c10c798b040d59c92f257cae597a3fc311d855c2ff53f1090ef5c722b38f" title="Set this flag if the allocation should have its own memory block. ">VMA_ALLOCATION_CREATE_DEDICATED_MEMORY_BIT</a> but it makes no sense - they will never be moved.</li>
|
|
<li>Both allocations made with or without <a class="el" href="vk__mem__alloc_8h.html#ad9889c10c798b040d59c92f257cae597a11da372cc3a82931c5e5d6146cd9dd1f" 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 pAllocations array.</li>
|
|
</ul>
|
|
<p>The function also frees empty <code>VkDeviceMemory</code> blocks.</p>
|
|
<p>After allocation has been moved, its <a class="el" href="struct_vma_allocation_info.html#ae0bfb7dfdf79a76ffefc9a94677a2f67" title="Handle to Vulkan memory object. ">VmaAllocationInfo::deviceMemory</a> and/or <a class="el" href="struct_vma_allocation_info.html#a4a3c732388dbdc7a23f9365b00825268" title="Offset into deviceMemory object to the beginning of this allocation, in bytes. (deviceMemory, offset) pair is unique to this allocation. ">VmaAllocationInfo::offset</a> changes. You must query them again using <a class="el" href="vk__mem__alloc_8h.html#a86dd08aba8633bfa4ad0df2e76481d8b" title="Returns current information about specified allocation and atomically marks it as used in current fra...">vmaGetAllocationInfo()</a> if you need them.</p>
|
|
<p>If an allocation has been moved, data in memory is copied to new place automatically, but if it was bound to a buffer or an image, you must destroy that object yourself, create new one and bind it to the new memory pointed by the allocation. You must use <code>vkDestroyBuffer()</code>, <code>vkDestroyImage()</code>, <code>vkCreateBuffer()</code>, <code>vkCreateImage()</code> for that purpose and NOT <a class="el" href="vk__mem__alloc_8h.html#a0d9f4e4ba5bf9aab1f1c746387753d77" title="Destroys Vulkan buffer and frees allocated memory.

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 data that needs to be moved. Some fragmentation still remains after this call. This is normal.</p>
|
|
<p>Warning: This function is not 100% correct according to Vulkan specification. Use it at your own risk. That's because Vulkan doesn't guarantee that memory requirements (size and alignment) for a new buffer or image are consistent. They may be different even for subsequent calls with the same parameters. It really does happen on some platforms, especially with images.</p>
|
|
<p>Warning: This function may be time-consuming, so you shouldn't call it too often (like every frame or 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). </p>

<p>This algorithm tries to find a memory type that:</p>
|
|
<ul>
|
|
<li>Is allowed by memoryTypeBits.</li>
|
|
<li>Contains all the flags from pAllocationCreateInfo->requiredFlags.</li>

<dl class="section return"><dt>Returns</dt><dd>Returns VK_ERROR_FEATURE_NOT_PRESENT if not found. Receiving such result from this function or any other allocating function probably means that your device doesn't support any memory type with requested features for the specific type of resource you want to use it for. Please check parameters of your resource, like image layout (OPTIMAL versus LINEAR) or mip level count. </dd></dl>

<p>Maps memory represented by given allocation and returns pointer to it. </p>

|
<p>Maps memory represented by given allocation to make it accessible to CPU code. When succeeded, <code>*ppData</code> contains pointer to first byte of this memory. If the allocation is part of bigger <code>VkDeviceMemory</code> block, the pointer is correctly offseted to the beginning of region assigned to this particular allocation.</p>
|
|
<p>Mapping is internally reference-counted and synchronized, so despite raw Vulkan function <code>vkMapMemory()</code> cannot be used to map same block of <code>VkDeviceMemory</code> multiple times simultaneously, it is safe to call this function on allocations assigned to the same memory block. Actual Vulkan memory will be mapped on first mapping and unmapped on last unmapping.</p>

<p>Sets pUserData in given allocation to new value. </p>
|
|
<p>If the allocation was created with VMA_ALLOCATION_CREATE_USER_DATA_COPY_STRING_BIT, pUserData must be either null, or pointer to a null-terminated string. The function makes local copy of the string and sets it as allocation's <code>pUserData</code>. String passed as pUserData doesn't need to be valid for whole lifetime of the allocation - you can free it after this call. String previously pointed by allocation's pUserData is freed from memory.</p>
|
|
<p>If the flag was not used, the value of pointer <code>pUserData</code> is just copied to allocation's <code>pUserData</code>. It is opaque, so you can use it however you want - e.g. as a pointer, ordinal number or some handle to you own data. </p>
