+// Added automatically by a large-scale-change that took the approach of
+// 'apply every license found to every target'. While this makes sure we respect
+// every license restriction, it may not be entirely correct.
+//
+// e.g. GPL in an MIT project might only apply to the contrib/ directory.
+//
+// Please consider splitting the single license below into multiple licenses,
+// taking care not to lose any license_kind information, and overriding the
+// default license using the 'licenses: [...]' property on targets as needed.
+//
+// For unused files, consider creating a 'fileGroup' with "//visibility:private"
+// to attach the license to, and including a comment whether the files may be
+// used in the current project.
+//
+// large-scale-change included anything that looked like it might be a license
+// text as a license_text. e.g. LICENSE, NOTICE, COPYING etc.
+//
+// Please consider removing redundant or irrelevant files from 'license_text:'.

+The Skia library is a cross-platform 2D-based renderer. The

+
+  include/  : contains public header files
+  src/      : contains src code
+
+The top level makefile is at the root: Android.mk

+These files originate from an upstream repository
+(skia.googlesource.com) where the project is actively developed

+\defgroup group_init Library initialization

+

+\brief API elements related to the initialization and management of the entire library, especially #VmaAllocator object.

+

+\defgroup group_alloc Memory allocation

+

+\brief API elements related to the allocation, deallocation, and management of Vulkan memory, buffers, images.

+Most basic ones being: vmaCreateBuffer(), vmaCreateImage().

+

+\defgroup group_virtual Virtual allocator

+

+\brief API elements related to the mechanism of \ref virtual_allocator - using the core allocation algorithm

+for user-defined purpose without allocating any real GPU memory.

+\section quick_start_project_setup Project setup

+

+Vulkan Memory Allocator comes in form of a "stb-style" single header file.

+You don't need to build it as a separate library project.

+You can add this file directly to your project and submit it to code repository next to your other source files.

+

+"Single header" doesn't mean that everything is contained in C/C++ declarations,

+like it tends to be in case of inline functions or C++ templates.

+It means that implementation is bundled with interface in a single file and needs to be extracted using preprocessor macro.

+If you don't do it properly, you will get linker errors.

+

+To do it properly:

+

+-# Include "vk_mem_alloc.h" file in each CPP file where you want to use the library.

+   This includes declarations of all members of the library.

+-# In exactly one CPP file define following macro before this include.

+   It enables also internal definitions.

+

+\code

+#define VMA_IMPLEMENTATION

+#include "vk_mem_alloc.h"

+\endcode

+

+It may be a good idea to create dedicated CPP file just for this purpose.

+

+This library includes header `<vulkan/vulkan.h>`, which in turn

+includes `<windows.h>` on Windows. If you need some specific macros defined

+before including these headers (like `WIN32_LEAN_AND_MEAN` or

+`WINVER` for Windows, `VK_USE_PLATFORM_WIN32_KHR` for Vulkan), you must define

+them before every `#include` of this library.

+

+This library is written in C++, but has C-compatible interface.

+Thus you can include and use vk_mem_alloc.h in C or C++ code, but full

+implementation with `VMA_IMPLEMENTATION` macro must be compiled as C++, NOT as C.

+Some features of C++14 used. STL containers, RTTI, or C++ exceptions are not used.

+

+

+\section quick_start_initialization Initialization

+

+At program startup:

+

+-# Initialize Vulkan to have `VkPhysicalDevice`, `VkDevice` and `VkInstance` object.

+-# Fill VmaAllocatorCreateInfo structure and create #VmaAllocator object by

+   calling vmaCreateAllocator().

+

+Only members `physicalDevice`, `device`, `instance` are required.

+However, you should inform the library which Vulkan version do you use by setting

+VmaAllocatorCreateInfo::vulkanApiVersion and which extensions did you enable

+by setting VmaAllocatorCreateInfo::flags (like #VMA_ALLOCATOR_CREATE_BUFFER_DEVICE_ADDRESS_BIT for VK_KHR_buffer_device_address).

+Otherwise, VMA would use only features of Vulkan 1.0 core with no extensions.

+

+You may need to configure importing Vulkan functions. There are 3 ways to do this:

+

+-# **If you link with Vulkan static library** (e.g. "vulkan-1.lib" on Windows):

+   - You don't need to do anything.

+   - VMA will use these, as macro `VMA_STATIC_VULKAN_FUNCTIONS` is defined to 1 by default.

+-# **If you want VMA to fetch pointers to Vulkan functions dynamically** using `vkGetInstanceProcAddr`,

+   `vkGetDeviceProcAddr` (this is the option presented in the example below):

+   - Define `VMA_STATIC_VULKAN_FUNCTIONS` to 0, `VMA_DYNAMIC_VULKAN_FUNCTIONS` to 1.

+   - Provide pointers to these two functions via VmaVulkanFunctions::vkGetInstanceProcAddr,

+     VmaVulkanFunctions::vkGetDeviceProcAddr.

+   - The library will fetch pointers to all other functions it needs internally.

+-# **If you fetch pointers to all Vulkan functions in a custom way**, e.g. using some loader like

+   [Volk](https://github.com/zeux/volk):

+   - Define `VMA_STATIC_VULKAN_FUNCTIONS` and `VMA_DYNAMIC_VULKAN_FUNCTIONS` to 0.

+   - Pass these pointers via structure #VmaVulkanFunctions.

+

+\code

+VmaVulkanFunctions vulkanFunctions = {};

+vulkanFunctions.vkGetInstanceProcAddr = &vkGetInstanceProcAddr;

+vulkanFunctions.vkGetDeviceProcAddr = &vkGetDeviceProcAddr;

+

+VmaAllocatorCreateInfo allocatorCreateInfo = {};

+allocatorCreateInfo.vulkanApiVersion = VK_API_VERSION_1_2;

+allocatorCreateInfo.physicalDevice = physicalDevice;

+allocatorCreateInfo.device = device;

+allocatorCreateInfo.instance = instance;

+allocatorCreateInfo.pVulkanFunctions = &vulkanFunctions;

+

+VmaAllocator allocator;

+vmaCreateAllocator(&allocatorCreateInfo, &allocator);

+\endcode

+

+

+\section quick_start_resource_allocation Resource allocation

+

+When you want to create a buffer or image:

+

+-# Fill `VkBufferCreateInfo` / `VkImageCreateInfo` structure.

+-# Fill VmaAllocationCreateInfo structure.

+-# Call vmaCreateBuffer() / vmaCreateImage() to get `VkBuffer`/`VkImage` with memory

+   already allocated and bound to it, plus #VmaAllocation objects that represents its underlying memory.

+

+\code

+VkBufferCreateInfo bufferInfo = { VK_STRUCTURE_TYPE_BUFFER_CREATE_INFO };

+bufferInfo.size = 65536;

+bufferInfo.usage = VK_BUFFER_USAGE_VERTEX_BUFFER_BIT | VK_BUFFER_USAGE_TRANSFER_DST_BIT;

+

+VmaAllocationCreateInfo allocInfo = {};

+allocInfo.usage = VMA_MEMORY_USAGE_AUTO;

+

+VkBuffer buffer;

+VmaAllocation allocation;

+vmaCreateBuffer(allocator, &bufferInfo, &allocInfo, &buffer, &allocation, nullptr);

+\endcode

+

+Don't forget to destroy your objects when no longer needed:

+

+\code

+vmaDestroyBuffer(allocator, buffer, allocation);

+vmaDestroyAllocator(allocator);

+\endcode

+

+

+\page choosing_memory_type Choosing memory type

+

+Physical devices in Vulkan support various combinations of memory heaps and

+types. Help with choosing correct and optimal memory type for your specific

+resource is one of the key features of this library. You can use it by filling

+appropriate members of VmaAllocationCreateInfo structure, as described below.

+You can also combine multiple methods.

+

+-# If you just want to find memory type index that meets your requirements, you

+   can use function: vmaFindMemoryTypeIndexForBufferInfo(),

+   vmaFindMemoryTypeIndexForImageInfo(), vmaFindMemoryTypeIndex().

+-# If you want to allocate a region of device memory without association with any

+   specific image or buffer, you can use function vmaAllocateMemory(). Usage of

+   this function is not recommended and usually not needed.

+   vmaAllocateMemoryPages() function is also provided for creating multiple allocations at once,

+   which may be useful for sparse binding.

+-# If you already have a buffer or an image created, you want to allocate memory

+   for it and then you will bind it yourself, you can use function

+   vmaAllocateMemoryForBuffer(), vmaAllocateMemoryForImage().

+   For binding you should use functions: vmaBindBufferMemory(), vmaBindImageMemory()

+   or their extended versions: vmaBindBufferMemory2(), vmaBindImageMemory2().

+-# **This is the easiest and recommended way to use this library:**

+   If you want to create a buffer or an image, allocate memory for it and bind

+   them together, all in one call, you can use function vmaCreateBuffer(),

+   vmaCreateImage().

+

+When using 3. or 4., the library internally queries Vulkan for memory types

+supported for that buffer or image (function `vkGetBufferMemoryRequirements()`)

+and uses only one of these types.

+

+If no memory type can be found that meets all the requirements, these functions

+return `VK_ERROR_FEATURE_NOT_PRESENT`.

+

+You can leave VmaAllocationCreateInfo structure completely filled with zeros.

+It means no requirements are specified for memory type.

+It is valid, although not very useful.

+

+\section choosing_memory_type_usage Usage

+

+The easiest way to specify memory requirements is to fill member

+VmaAllocationCreateInfo::usage using one of the values of enum #VmaMemoryUsage.

+It defines high level, common usage types.

+Since version 3 of the library, it is recommended to use #VMA_MEMORY_USAGE_AUTO to let it select best memory type for your resource automatically.

+

+For example, if you want to create a uniform buffer that will be filled using

+transfer only once or infrequently and then used for rendering every frame as a uniform buffer, you can

+do it using following code. The buffer will most likely end up in a memory type with

+`VK_MEMORY_PROPERTY_DEVICE_LOCAL_BIT` to be fast to access by the GPU device.

+

+\code

+VkBufferCreateInfo bufferInfo = { VK_STRUCTURE_TYPE_BUFFER_CREATE_INFO };

+bufferInfo.size = 65536;

+bufferInfo.usage = VK_BUFFER_USAGE_UNIFORM_BUFFER_BIT | VK_BUFFER_USAGE_TRANSFER_DST_BIT;

+

+VmaAllocationCreateInfo allocInfo = {};

+allocInfo.usage = VMA_MEMORY_USAGE_AUTO;

+

+VkBuffer buffer;

+VmaAllocation allocation;

+vmaCreateBuffer(allocator, &bufferInfo, &allocInfo, &buffer, &allocation, nullptr);

+\endcode

+

+If you have a preference for putting the resource in GPU (device) memory or CPU (host) memory

+on systems with discrete graphics card that have the memories separate, you can use

+#VMA_MEMORY_USAGE_AUTO_PREFER_DEVICE or #VMA_MEMORY_USAGE_AUTO_PREFER_HOST.

+

+When using `VMA_MEMORY_USAGE_AUTO*` while you want to map the allocated memory,

+you also need to specify one of the host access flags:

+#VMA_ALLOCATION_CREATE_HOST_ACCESS_SEQUENTIAL_WRITE_BIT or #VMA_ALLOCATION_CREATE_HOST_ACCESS_RANDOM_BIT.

+This will help the library decide about preferred memory type to ensure it has `VK_MEMORY_PROPERTY_HOST_VISIBLE_BIT`

+so you can map it.

+

+For example, a staging buffer that will be filled via mapped pointer and then

+used as a source of transfer to the buffer decribed previously can be created like this.

+It will likely and up in a memory type that is `HOST_VISIBLE` and `HOST_COHERENT`

+but not `HOST_CACHED` (meaning uncached, write-combined) and not `DEVICE_LOCAL` (meaning system RAM).

+

+\code

+VkBufferCreateInfo stagingBufferInfo = { VK_STRUCTURE_TYPE_BUFFER_CREATE_INFO };

+stagingBufferInfo.size = 65536;

+stagingBufferInfo.usage = VK_BUFFER_USAGE_TRANSFER_SRC_BIT;

+

+VmaAllocationCreateInfo stagingAllocInfo = {};

+stagingAllocInfo.usage = VMA_MEMORY_USAGE_AUTO;

+stagingAllocInfo.flags = VMA_ALLOCATION_CREATE_HOST_ACCESS_SEQUENTIAL_WRITE_BIT;

+

+VkBuffer stagingBuffer;

+VmaAllocation stagingAllocation;

+vmaCreateBuffer(allocator, &stagingBufferInfo, &stagingAllocInfo, &stagingBuffer, &stagingAllocation, nullptr);

+\endcode

+

+For more examples of creating different kinds of resources, see chapter \ref usage_patterns.

+

+Usage values `VMA_MEMORY_USAGE_AUTO*` are legal to use only when the library knows

+about the resource being created by having `VkBufferCreateInfo` / `VkImageCreateInfo` passed,

+so they work with functions like: vmaCreateBuffer(), vmaCreateImage(), vmaFindMemoryTypeIndexForBufferInfo() etc.

+If you allocate raw memory using function vmaAllocateMemory(), you have to use other means of selecting

+memory type, as decribed below.

+

+\note

+Old usage values (`VMA_MEMORY_USAGE_GPU_ONLY`, `VMA_MEMORY_USAGE_CPU_ONLY`,

+`VMA_MEMORY_USAGE_CPU_TO_GPU`, `VMA_MEMORY_USAGE_GPU_TO_CPU`, `VMA_MEMORY_USAGE_CPU_COPY`)

+are still available and work same way as in previous versions of the library

+for backward compatibility, but they are not recommended.

+

+\section choosing_memory_type_required_preferred_flags Required and preferred flags

+

+You can specify more detailed requirements by filling members

+VmaAllocationCreateInfo::requiredFlags and VmaAllocationCreateInfo::preferredFlags

+with a combination of bits from enum `VkMemoryPropertyFlags`. For example,

+if you want to create a buffer that will be persistently mapped on host (so it

+must be `HOST_VISIBLE`) and preferably will also be `HOST_COHERENT` and `HOST_CACHED`,

+use following code:

+

+\code

+VmaAllocationCreateInfo allocInfo = {};

+allocInfo.requiredFlags = VK_MEMORY_PROPERTY_HOST_VISIBLE_BIT;

+allocInfo.preferredFlags = VK_MEMORY_PROPERTY_HOST_COHERENT_BIT | VK_MEMORY_PROPERTY_HOST_CACHED_BIT;

+allocInfo.flags = VMA_ALLOCATION_CREATE_HOST_ACCESS_RANDOM_BIT | VMA_ALLOCATION_CREATE_MAPPED_BIT;

+

+VkBuffer buffer;

+VmaAllocation allocation;

+vmaCreateBuffer(allocator, &bufferInfo, &allocInfo, &buffer, &allocation, nullptr);

+\endcode

+

+A memory type is chosen that has all the required flags and as many preferred

+flags set as possible.

+

+Value passed in VmaAllocationCreateInfo::usage is internally converted to a set of required and preferred flags,

+plus some extra "magic" (heuristics).

+

+\section choosing_memory_type_explicit_memory_types Explicit memory types

+

+If you inspected memory types available on the physical device and you have

+a preference for memory types that you want to use, you can fill member

+VmaAllocationCreateInfo::memoryTypeBits. It is a bit mask, where each bit set

+means that a memory type with that index is allowed to be used for the

+allocation. Special value 0, just like `UINT32_MAX`, means there are no

+restrictions to memory type index.

+

+Please note that this member is NOT just a memory type index.

+Still you can use it to choose just one, specific memory type.

+For example, if you already determined that your buffer should be created in

+memory type 2, use following code:

+

+\code

+uint32_t memoryTypeIndex = 2;

+

+VmaAllocationCreateInfo allocInfo = {};

+allocInfo.memoryTypeBits = 1u << memoryTypeIndex;

+

+VkBuffer buffer;

+VmaAllocation allocation;

+vmaCreateBuffer(allocator, &bufferInfo, &allocInfo, &buffer, &allocation, nullptr);

+\endcode

+

+

+\section choosing_memory_type_custom_memory_pools Custom memory pools

+

+If you allocate from custom memory pool, all the ways of specifying memory

+requirements described above are not applicable and the aforementioned members

+of VmaAllocationCreateInfo structure are ignored. Memory type is selected

+explicitly when creating the pool and then used to make all the allocations from

+that pool. For further details, see \ref custom_memory_pools.

+

+\section choosing_memory_type_dedicated_allocations Dedicated allocations

+

+Memory for allocations is reserved out of larger block of `VkDeviceMemory`

+allocated from Vulkan internally. That is the main feature of this whole library.

+You can still request a separate memory block to be created for an allocation,

+just like you would do in a trivial solution without using any allocator.

+In that case, a buffer or image is always bound to that memory at offset 0.

+This is called a "dedicated allocation".

+You can explicitly request it by using flag #VMA_ALLOCATION_CREATE_DEDICATED_MEMORY_BIT.

+The library can also internally decide to use dedicated allocation in some cases, e.g.:

+

+- When the size of the allocation is large.

+- When [VK_KHR_dedicated_allocation](@ref vk_khr_dedicated_allocation) extension is enabled

+  and it reports that dedicated allocation is required or recommended for the resource.

+- When allocation of next big memory block fails due to not enough device memory,

+  but allocation with the exact requested size succeeds.

+

+

+\page memory_mapping Memory mapping

+

+To "map memory" in Vulkan means to obtain a CPU pointer to `VkDeviceMemory`,

+to be able to read from it or write to it in CPU code.

+Mapping is possible only of memory allocated from a memory type that has

+`VK_MEMORY_PROPERTY_HOST_VISIBLE_BIT` flag.

+Functions `vkMapMemory()`, `vkUnmapMemory()` are designed for this purpose.

+You can use them directly with memory allocated by this library,

+but it is not recommended because of following issue:

+Mapping the same `VkDeviceMemory` block multiple times is illegal - only one mapping at a time is allowed.

+This includes mapping disjoint regions. Mapping is not reference-counted internally by Vulkan.

+Because of this, Vulkan Memory Allocator provides following facilities:

+

+\note If you want to be able to map an allocation, you need to specify one of the flags

+#VMA_ALLOCATION_CREATE_HOST_ACCESS_SEQUENTIAL_WRITE_BIT or #VMA_ALLOCATION_CREATE_HOST_ACCESS_RANDOM_BIT

+in VmaAllocationCreateInfo::flags. These flags are required for an allocation to be mappable

+when using #VMA_MEMORY_USAGE_AUTO or other `VMA_MEMORY_USAGE_AUTO*` enum values.

+For other usage values they are ignored and every such allocation made in `HOST_VISIBLE` memory type is mappable,

+but they can still be used for consistency.

+

+\section memory_mapping_mapping_functions Mapping functions

+

+The library provides following functions for mapping of a specific #VmaAllocation: vmaMapMemory(), vmaUnmapMemory().

+They are safer and more convenient to use than standard Vulkan functions.

+You can map an allocation multiple times simultaneously - mapping is reference-counted internally.

+You can also map different allocations simultaneously regardless of whether they use the same `VkDeviceMemory` block.

+The way it is implemented is that the library always maps entire memory block, not just region of the allocation.

+For further details, see description of vmaMapMemory() function.

+Example:

+

+\code

+// Having these objects initialized:

+struct ConstantBuffer

+{

+    ...

+};

+ConstantBuffer constantBufferData = ...

+

+VmaAllocator allocator = ...

+VkBuffer constantBuffer = ...

+VmaAllocation constantBufferAllocation = ...

+

+// You can map and fill your buffer using following code:

+

+void* mappedData;

+vmaMapMemory(allocator, constantBufferAllocation, &mappedData);

+memcpy(mappedData, &constantBufferData, sizeof(constantBufferData));

+vmaUnmapMemory(allocator, constantBufferAllocation);

+\endcode

+

+When mapping, you may see a warning from Vulkan validation layer similar to this one:

+

+<i>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.</i>

+

+It happens 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.

+You can safely ignore it if you are sure you access only memory of the intended

+object that you wanted to map.

+

+

+\section memory_mapping_persistently_mapped_memory Persistently mapped memory

+

+Kepping your memory persistently mapped is generally OK in Vulkan.

+You don't need to unmap it before using its data on the GPU.

+The library provides a special feature designed for that:

+Allocations made with #VMA_ALLOCATION_CREATE_MAPPED_BIT flag set in

+VmaAllocationCreateInfo::flags stay mapped all the time,

+so you can just access CPU pointer to it any time

+without a need to call any "map" or "unmap" function.

+Example:

+

+\code

+VkBufferCreateInfo bufCreateInfo = { VK_STRUCTURE_TYPE_BUFFER_CREATE_INFO };

+bufCreateInfo.size = sizeof(ConstantBuffer);

+bufCreateInfo.usage = VK_BUFFER_USAGE_TRANSFER_SRC_BIT;

+

+VmaAllocationCreateInfo allocCreateInfo = {};

+allocCreateInfo.usage = VMA_MEMORY_USAGE_AUTO;

+allocCreateInfo.flags = VMA_ALLOCATION_CREATE_HOST_ACCESS_SEQUENTIAL_WRITE_BIT |

+    VMA_ALLOCATION_CREATE_MAPPED_BIT;

+

+VkBuffer buf;

+VmaAllocation alloc;

+VmaAllocationInfo allocInfo;

+vmaCreateBuffer(allocator, &bufCreateInfo, &allocCreateInfo, &buf, &alloc, &allocInfo);

+

+// Buffer is already mapped. You can access its memory.

+memcpy(allocInfo.pMappedData, &constantBufferData, sizeof(constantBufferData));

+\endcode

+

+\note #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 \ref usage_patterns_advanced_data_uploading.

+

+\section memory_mapping_cache_control Cache flush and invalidate

+

+Memory in Vulkan doesn't need to be unmapped before using it on GPU,

+but unless a memory types has `VK_MEMORY_PROPERTY_HOST_COHERENT_BIT` flag set,

+you need to manually **invalidate** cache before reading of mapped pointer

+and **flush** cache after writing to mapped pointer.

+Map/unmap operations don't do that automatically.

+Vulkan provides following functions for this purpose `vkFlushMappedMemoryRanges()`,

+`vkInvalidateMappedMemoryRanges()`, but this library provides more convenient

+functions that refer to given allocation object: vmaFlushAllocation(),

+vmaInvalidateAllocation(),

+or multiple objects at once: vmaFlushAllocations(), vmaInvalidateAllocations().

+

+Regions of memory specified for flush/invalidate must be aligned to

+`VkPhysicalDeviceLimits::nonCoherentAtomSize`. This is automatically ensured by the library.

+In any memory type that is `HOST_VISIBLE` but not `HOST_COHERENT`, all allocations

+within blocks are aligned to this value, so their offsets are always multiply of

+`nonCoherentAtomSize` and two different allocations never share same "line" of this size.

+

+Also, Windows drivers from all 3 PC GPU vendors (AMD, Intel, NVIDIA)

+currently provide `HOST_COHERENT` flag on all memory types that are

+`HOST_VISIBLE`, so on PC you may not need to bother.

+

+

+\page staying_within_budget Staying within budget

+

+When developing a graphics-intensive game or program, it is important to avoid allocating

+more GPU memory than it is physically available. When the memory is over-committed,

+various bad things can happen, depending on the specific GPU, graphics driver, and

+operating system:

+

+- It may just work without any problems.

+- The application may slow down because some memory blocks are moved to system RAM

+  and the GPU has to access them through PCI Express bus.

+- A new allocation may take very long time to complete, even few seconds, and possibly

+  freeze entire system.

+- The new allocation may fail with `VK_ERROR_OUT_OF_DEVICE_MEMORY`.

+- It may even result in GPU crash (TDR), observed as `VK_ERROR_DEVICE_LOST`

+  returned somewhere later.

+

+\section staying_within_budget_querying_for_budget Querying for budget

+

+To query for current memory usage and available budget, use function vmaGetHeapBudgets().

+Returned structure #VmaBudget contains quantities expressed in bytes, per Vulkan memory heap.

+

+Please note that this function returns different information and works faster than

+vmaCalculateStatistics(). vmaGetHeapBudgets() can be called every frame or even before every

+allocation, while vmaCalculateStatistics() is intended to be used rarely,

+only to obtain statistical information, e.g. for debugging purposes.

+

+It is recommended to use <b>VK_EXT_memory_budget</b> device extension to obtain information

+about the budget from Vulkan device. VMA is able to use this extension automatically.

+When not enabled, the allocator behaves same way, but then it estimates current usage

+and available budget based on its internal information and Vulkan memory heap sizes,

+which may be less precise. In order to use this extension:

+

+1. Make sure extensions VK_EXT_memory_budget and VK_KHR_get_physical_device_properties2

+   required by it are available and enable them. Please note that the first is a device

+   extension and the second is instance extension!

+2. Use flag #VMA_ALLOCATOR_CREATE_EXT_MEMORY_BUDGET_BIT when creating #VmaAllocator object.

+3. Make sure to call vmaSetCurrentFrameIndex() every frame. Budget is queried from

+   Vulkan inside of it to avoid overhead of querying it with every allocation.

+

+\section staying_within_budget_controlling_memory_usage Controlling memory usage

+

+There are many ways in which you can try to stay within the budget.

+

+First, when making new allocation requires allocating a new memory block, the library

+tries not to exceed the budget automatically. If a block with default recommended size

+(e.g. 256 MB) would go over budget, a smaller block is allocated, possibly even

+dedicated memory for just this resource.

+

+If the size of the requested resource plus current memory usage is more than the

+budget, by default the library still tries to create it, leaving it to the Vulkan

+implementation whether the allocation succeeds or fails. You can change this behavior

+by using #VMA_ALLOCATION_CREATE_WITHIN_BUDGET_BIT flag. With it, the allocation is

+not made if it would exceed the budget or if the budget is already exceeded.

+VMA then tries to make the allocation from the next eligible Vulkan memory type.

+The all of them fail, the call then fails with `VK_ERROR_OUT_OF_DEVICE_MEMORY`.

+Example usage pattern may be to pass the #VMA_ALLOCATION_CREATE_WITHIN_BUDGET_BIT flag

+when creating resources that are not essential for the application (e.g. the texture

+of a specific object) and not to pass it when creating critically important resources

+(e.g. render targets).

+

+On AMD graphics cards there is a custom vendor extension available: <b>VK_AMD_memory_overallocation_behavior</b>

+that allows to control the behavior of the Vulkan implementation in out-of-memory cases -

+whether it should fail with an error code or still allow the allocation.

+Usage of this extension involves only passing extra structure on Vulkan device creation,

+so it is out of scope of this library.

+

+Finally, you can also use #VMA_ALLOCATION_CREATE_NEVER_ALLOCATE_BIT flag to make sure

+a new allocation is created only when it fits inside one of the existing memory blocks.

+If it would require to allocate a new block, if fails instead with `VK_ERROR_OUT_OF_DEVICE_MEMORY`.

+This also ensures that the function call is very fast because it never goes to Vulkan

+to obtain a new block.

+

+\note Creating \ref custom_memory_pools with VmaPoolCreateInfo::minBlockCount

+set to more than 0 will currently try to allocate memory blocks without checking whether they

+fit within budget.

+

+

+\page resource_aliasing Resource aliasing (overlap)

+

+New explicit graphics APIs (Vulkan and Direct3D 12), thanks to manual memory

+management, give an opportunity to alias (overlap) multiple resources in the

+same region of memory - a feature not available in the old APIs (Direct3D 11, OpenGL).

+It can be useful to save video memory, but it must be used with caution.

+

+For example, if you know the flow of your whole render frame in advance, you

+are going to use some intermediate textures or buffers only during a small range of render passes,

+and you know these ranges don't overlap in time, you can bind these resources to

+the same place in memory, even if they have completely different parameters (width, height, format etc.).

+

+![Resource aliasing (overlap)](../gfx/Aliasing.png)

+

+Such scenario is possible using VMA, but you need to create your images manually.

+Then you need to calculate parameters of an allocation to be made using formula:

+

+- allocation size = max(size of each image)

+- allocation alignment = max(alignment of each image)

+- allocation memoryTypeBits = bitwise AND(memoryTypeBits of each image)

+

+Following example shows two different images bound to the same place in memory,

+allocated to fit largest of them.

+

+\code

+// A 512x512 texture to be sampled.

+VkImageCreateInfo img1CreateInfo = { VK_STRUCTURE_TYPE_IMAGE_CREATE_INFO };

+img1CreateInfo.imageType = VK_IMAGE_TYPE_2D;

+img1CreateInfo.extent.width = 512;

+img1CreateInfo.extent.height = 512;

+img1CreateInfo.extent.depth = 1;

+img1CreateInfo.mipLevels = 10;

+img1CreateInfo.arrayLayers = 1;

+img1CreateInfo.format = VK_FORMAT_R8G8B8A8_SRGB;

+img1CreateInfo.tiling = VK_IMAGE_TILING_OPTIMAL;

+img1CreateInfo.initialLayout = VK_IMAGE_LAYOUT_UNDEFINED;

+img1CreateInfo.usage = VK_IMAGE_USAGE_TRANSFER_DST_BIT | VK_IMAGE_USAGE_SAMPLED_BIT;

+img1CreateInfo.samples = VK_SAMPLE_COUNT_1_BIT;

+

+// A full screen texture to be used as color attachment.

+VkImageCreateInfo img2CreateInfo = { VK_STRUCTURE_TYPE_IMAGE_CREATE_INFO };

+img2CreateInfo.imageType = VK_IMAGE_TYPE_2D;

+img2CreateInfo.extent.width = 1920;

+img2CreateInfo.extent.height = 1080;

+img2CreateInfo.extent.depth = 1;

+img2CreateInfo.mipLevels = 1;

+img2CreateInfo.arrayLayers = 1;

+img2CreateInfo.format = VK_FORMAT_R8G8B8A8_UNORM;

+img2CreateInfo.tiling = VK_IMAGE_TILING_OPTIMAL;

+img2CreateInfo.initialLayout = VK_IMAGE_LAYOUT_UNDEFINED;

+img2CreateInfo.usage = VK_IMAGE_USAGE_SAMPLED_BIT | VK_IMAGE_USAGE_COLOR_ATTACHMENT_BIT;

+img2CreateInfo.samples = VK_SAMPLE_COUNT_1_BIT;

+

+VkImage img1;

+res = vkCreateImage(device, &img1CreateInfo, nullptr, &img1);

+VkImage img2;

+res = vkCreateImage(device, &img2CreateInfo, nullptr, &img2);

+

+VkMemoryRequirements img1MemReq;

+vkGetImageMemoryRequirements(device, img1, &img1MemReq);

+VkMemoryRequirements img2MemReq;

+vkGetImageMemoryRequirements(device, img2, &img2MemReq);

+

+VkMemoryRequirements finalMemReq = {};

+finalMemReq.size = std::max(img1MemReq.size, img2MemReq.size);

+finalMemReq.alignment = std::max(img1MemReq.alignment, img2MemReq.alignment);

+finalMemReq.memoryTypeBits = img1MemReq.memoryTypeBits & img2MemReq.memoryTypeBits;

+// Validate if(finalMemReq.memoryTypeBits != 0)

+

+VmaAllocationCreateInfo allocCreateInfo = {};

+allocCreateInfo.preferredFlags = VK_MEMORY_PROPERTY_DEVICE_LOCAL_BIT;

+

+VmaAllocation alloc;

+res = vmaAllocateMemory(allocator, &finalMemReq, &allocCreateInfo, &alloc, nullptr);

+

+res = vmaBindImageMemory(allocator, alloc, img1);

+res = vmaBindImageMemory(allocator, alloc, img2);

+

+// You can use img1, img2 here, but not at the same time!

+

+vmaFreeMemory(allocator, alloc);

+vkDestroyImage(allocator, img2, nullptr);

+vkDestroyImage(allocator, img1, nullptr);

+\endcode

+

+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`.

+

+Additional considerations:

+

+- Vulkan also allows to interpret contents of memory between aliasing resources consistently in some cases.

+See chapter 11.8. "Memory Aliasing" of Vulkan specification or `VK_IMAGE_CREATE_ALIAS_BIT` flag.

+- You can create more complex layout where different images and buffers are bound

+at different offsets inside one large allocation. For example, one can imagine

+a big texture used in some render passes, aliasing with a set of many small buffers

+used between in some further passes. To bind a resource at non-zero offset in an allocation,

+use vmaBindBufferMemory2() / vmaBindImageMemory2().

+- Before allocating memory for the resources you want to alias, check `memoryTypeBits`

+returned in memory requirements of each resource to make sure the bits overlap.

+Some GPUs may expose multiple memory types suitable e.g. only for buffers or

+images with `COLOR_ATTACHMENT` usage, so the sets of memory types supported by your

+resources may be disjoint. Aliasing them is not possible in that case.

+

+

+\page custom_memory_pools Custom memory pools

+

+A memory pool contains a number of `VkDeviceMemory` blocks.

+The library automatically creates and manages default pool for each memory type available on the device.

+Default memory pool automatically grows in size.

+Size of allocated blocks is also variable and managed automatically.

+

+You can create custom pool and allocate memory out of it.

+It can be useful if you want to:

+

+- Keep certain kind of allocations separate from others.

+- Enforce particular, fixed size of Vulkan memory blocks.

+- Limit maximum amount of Vulkan memory allocated for that pool.

+- Reserve minimum or fixed amount of Vulkan memory always preallocated for that pool.

+- Use extra parameters for a set of your allocations that are available in #VmaPoolCreateInfo but not in

+  #VmaAllocationCreateInfo - e.g., custom minimum alignment, custom `pNext` chain.

+- Perform defragmentation on a specific subset of your allocations.

+

+To use custom memory pools:

+

+-# Fill VmaPoolCreateInfo structure.

+-# Call vmaCreatePool() to obtain #VmaPool handle.

+-# When making an allocation, set VmaAllocationCreateInfo::pool to this handle.

+   You don't need to specify any other parameters of this structure, like `usage`.

+

+Example:

+

+\code

+// Find memoryTypeIndex for the pool.

+VkBufferCreateInfo sampleBufCreateInfo = { VK_STRUCTURE_TYPE_BUFFER_CREATE_INFO };

+sampleBufCreateInfo.size = 0x10000; // Doesn't matter.

+sampleBufCreateInfo.usage = VK_BUFFER_USAGE_UNIFORM_BUFFER_BIT | VK_BUFFER_USAGE_TRANSFER_DST_BIT;

+

+VmaAllocationCreateInfo sampleAllocCreateInfo = {};

+sampleAllocCreateInfo.usage = VMA_MEMORY_USAGE_AUTO;

+

+uint32_t memTypeIndex;

+VkResult res = vmaFindMemoryTypeIndexForBufferInfo(allocator,

+    &sampleBufCreateInfo, &sampleAllocCreateInfo, &memTypeIndex);

+// Check res...

+

+// Create a pool that can have at most 2 blocks, 128 MiB each.

+VmaPoolCreateInfo poolCreateInfo = {};

+poolCreateInfo.memoryTypeIndex = memTypeIndex;

+poolCreateInfo.blockSize = 128ull * 1024 * 1024;

+poolCreateInfo.maxBlockCount = 2;

+

+VmaPool pool;

+res = vmaCreatePool(allocator, &poolCreateInfo, &pool);

+// Check res...

+

+// Allocate a buffer out of it.

+VkBufferCreateInfo bufCreateInfo = { VK_STRUCTURE_TYPE_BUFFER_CREATE_INFO };

+bufCreateInfo.size = 1024;

+bufCreateInfo.usage = VK_BUFFER_USAGE_UNIFORM_BUFFER_BIT | VK_BUFFER_USAGE_TRANSFER_DST_BIT;

+

+VmaAllocationCreateInfo allocCreateInfo = {};

+allocCreateInfo.pool = pool;

+

+VkBuffer buf;

+VmaAllocation alloc;

+res = vmaCreateBuffer(allocator, &bufCreateInfo, &allocCreateInfo, &buf, &alloc, nullptr);

+// Check res...

+\endcode

+

+You have to free all allocations made from this pool before destroying it.

+

+\code

+vmaDestroyBuffer(allocator, buf, alloc);

+vmaDestroyPool(allocator, pool);

+\endcode

+

+New versions of this library support creating dedicated allocations in custom pools.

+It is supported only when VmaPoolCreateInfo::blockSize = 0.

+To use this feature, set VmaAllocationCreateInfo::pool to the pointer to your custom pool and

+VmaAllocationCreateInfo::flags to #VMA_ALLOCATION_CREATE_DEDICATED_MEMORY_BIT.

+

+\note Excessive use of custom pools is a common mistake when using this library.

+Custom pools may be useful for special purposes - when you want to

+keep certain type of resources separate e.g. to reserve minimum amount of memory

+for them or limit maximum amount of memory they can occupy. For most

+resources this is not needed and so it is not recommended to create #VmaPool

+objects and allocations out of them. Allocating from the default pool is sufficient.

+

+

+\section custom_memory_pools_MemTypeIndex Choosing memory type index

+

+When creating a pool, you must explicitly specify memory type index.

+To find the one suitable for your buffers or images, you can use helper functions

+vmaFindMemoryTypeIndexForBufferInfo(), vmaFindMemoryTypeIndexForImageInfo().

+You need to provide structures with example parameters of buffers or images

+that you are going to create in that pool.

+

+\code

+VkBufferCreateInfo exampleBufCreateInfo = { VK_STRUCTURE_TYPE_BUFFER_CREATE_INFO };

+exampleBufCreateInfo.size = 1024; // Doesn't matter

+exampleBufCreateInfo.usage = VK_BUFFER_USAGE_UNIFORM_BUFFER_BIT | VK_BUFFER_USAGE_TRANSFER_DST_BIT;

+

+VmaAllocationCreateInfo allocCreateInfo = {};

+allocCreateInfo.usage = VMA_MEMORY_USAGE_AUTO;

+

+uint32_t memTypeIndex;

+vmaFindMemoryTypeIndexForBufferInfo(allocator, &exampleBufCreateInfo, &allocCreateInfo, &memTypeIndex);

+

+VmaPoolCreateInfo poolCreateInfo = {};

+poolCreateInfo.memoryTypeIndex = memTypeIndex;

+// ...

+\endcode

+

+When creating buffers/images allocated in that pool, provide following parameters:

+

+- `VkBufferCreateInfo`: Prefer to pass same parameters as above.

+  Otherwise you risk creating resources in a memory type that is not suitable for them, which may result in undefined behavior.

+  Using different `VK_BUFFER_USAGE_` flags may work, but you shouldn't create images in a pool intended for buffers

+  or the other way around.

+- VmaAllocationCreateInfo: You don't need to pass same parameters. Fill only `pool` member.

+  Other members are ignored anyway.

+

+\section linear_algorithm Linear allocation algorithm

+

+Each Vulkan memory block managed by this library has accompanying metadata that

+keeps track of used and unused regions. By default, the metadata structure and

+algorithm tries to find best place for new allocations among free regions to

+optimize memory usage. This way you can allocate and free objects in any order.

+

+![Default allocation algorithm](../gfx/Linear_allocator_1_algo_default.png)

+

+Sometimes there is a need to use simpler, linear allocation algorithm. You can

+create custom pool that uses such algorithm by adding flag

+#VMA_POOL_CREATE_LINEAR_ALGORITHM_BIT to VmaPoolCreateInfo::flags while creating

+#VmaPool object. Then an alternative metadata management is used. It always

+creates new allocations after last one and doesn't reuse free regions after

+allocations freed in the middle. It results in better allocation performance and

+less memory consumed by metadata.

+

+![Linear allocation algorithm](../gfx/Linear_allocator_2_algo_linear.png)

+

+With this one flag, you can create a custom pool that can be used in many ways:

+free-at-once, stack, double stack, and ring buffer. See below for details.

+You don't need to specify explicitly which of these options you are going to use - it is detected automatically.

+

+\subsection linear_algorithm_free_at_once Free-at-once

+

+In a pool that uses linear algorithm, you still need to free all the allocations

+individually, e.g. by using vmaFreeMemory() or vmaDestroyBuffer(). You can free

+them in any order. New allocations are always made after last one - free space

+in the middle is not reused. However, when you release all the allocation and

+the pool becomes empty, allocation starts from the beginning again. This way you

+can use linear algorithm to speed up creation of allocations that you are going

+to release all at once.

+

+![Free-at-once](../gfx/Linear_allocator_3_free_at_once.png)

+

+This mode is also available for pools created with VmaPoolCreateInfo::maxBlockCount

+value that allows multiple memory blocks.

+

+\subsection linear_algorithm_stack Stack

+

+When you free an allocation that was created last, its space can be reused.

+Thanks to this, if you always release allocations in the order opposite to their

+creation (LIFO - Last In First Out), you can achieve behavior of a stack.

+

+![Stack](../gfx/Linear_allocator_4_stack.png)

+

+This mode is also available for pools created with VmaPoolCreateInfo::maxBlockCount

+value that allows multiple memory blocks.

+

+\subsection linear_algorithm_double_stack Double stack

+

+The space reserved by a custom pool with linear algorithm may be used by two

+stacks:

+

+- First, default one, growing up from offset 0.

+- Second, "upper" one, growing down from the end towards lower offsets.

+

+To make allocation from the upper stack, add flag #VMA_ALLOCATION_CREATE_UPPER_ADDRESS_BIT

+to VmaAllocationCreateInfo::flags.

+

+![Double stack](../gfx/Linear_allocator_7_double_stack.png)

+

+Double stack is available only in pools with one memory block -

+VmaPoolCreateInfo::maxBlockCount must be 1. Otherwise behavior is undefined.

+

+When the two stacks' ends meet so there is not enough space between them for a

+new allocation, such allocation fails with usual

+`VK_ERROR_OUT_OF_DEVICE_MEMORY` error.

+

+\subsection linear_algorithm_ring_buffer Ring buffer

+

+When you free some allocations from the beginning and there is not enough free space

+for a new one at the end of a pool, allocator's "cursor" wraps around to the

+beginning and starts allocation there. Thanks to this, if you always release

+allocations in the same order as you created them (FIFO - First In First Out),

+you can achieve behavior of a ring buffer / queue.

+

+![Ring buffer](../gfx/Linear_allocator_5_ring_buffer.png)

+

+Ring buffer is available only in pools with one memory block -

+VmaPoolCreateInfo::maxBlockCount must be 1. Otherwise behavior is undefined.

+

+\note \ref defragmentation is not supported in custom pools created with #VMA_POOL_CREATE_LINEAR_ALGORITHM_BIT.

+

+

+\page defragmentation Defragmentation

+

+Interleaved allocations and deallocations of many objects of varying size can

+cause fragmentation over time, which can lead to a situation where the library is unable

+to find a continuous range of free memory for a new allocation despite there is

+enough free space, just scattered across many small free ranges between existing

+allocations.

+

+To mitigate this problem, you can use defragmentation feature.

+It doesn't happen automatically though and needs your cooperation,

+because VMA is a low level library that only allocates memory.

+It cannot recreate buffers and images in a new place as it doesn't remember the contents of `VkBufferCreateInfo` / `VkImageCreateInfo` structures.

+It cannot copy their contents as it doesn't record any commands to a command buffer.

+

+Example:

+

+\code

+VmaDefragmentationInfo defragInfo = {};

+defragInfo.pool = myPool;

+defragInfo.flags = VMA_DEFRAGMENTATION_FLAG_ALGORITHM_FAST_BIT;

+

+VmaDefragmentationContext defragCtx;

+VkResult res = vmaBeginDefragmentation(allocator, &defragInfo, &defragCtx);

+// Check res...

+

+for(;;)

+{

+    VmaDefragmentationPassMoveInfo pass;

+    res = vmaBeginDefragmentationPass(allocator, defragCtx, &pass);

+    if(res == VK_SUCCESS)

+        break;

+    else if(res != VK_INCOMPLETE)

+        // Handle error...

+

+    for(uint32_t i = 0; i < pass.moveCount; ++i)

+    {

+        // Inspect pass.pMoves[i].srcAllocation, identify what buffer/image it represents.

+        VmaAllocationInfo allocInfo;

+        vmaGetAllocationInfo(allocator, pMoves[i].srcAllocation, &allocInfo);

+        MyEngineResourceData* resData = (MyEngineResourceData*)allocInfo.pUserData;

+            

+        // Recreate and bind this buffer/image at: pass.pMoves[i].dstMemory, pass.pMoves[i].dstOffset.

+        VkImageCreateInfo imgCreateInfo = ...

+        VkImage newImg;

+        res = vkCreateImage(device, &imgCreateInfo, nullptr, &newImg);

+        // Check res...

+        res = vmaBindImageMemory(allocator, pMoves[i].dstTmpAllocation, newImg);

+        // Check res...

+

+        // Issue a vkCmdCopyBuffer/vkCmdCopyImage to copy its content to the new place.

+        vkCmdCopyImage(cmdBuf, resData->img, ..., newImg, ...);

+    }

+        

+    // Make sure the copy commands finished executing.

+    vkWaitForFences(...);

+

+    // Destroy old buffers/images bound with pass.pMoves[i].srcAllocation.

+    for(uint32_t i = 0; i < pass.moveCount; ++i)

+    {

+        // ...

+        vkDestroyImage(device, resData->img, nullptr);

+    }

+

+    // Update appropriate descriptors to point to the new places...

+        

+    res = vmaEndDefragmentationPass(allocator, defragCtx, &pass);

+    if(res == VK_SUCCESS)

+        break;

+    else if(res != VK_INCOMPLETE)

+        // Handle error...

+}

+

+vmaEndDefragmentation(allocator, defragCtx, nullptr);

+\endcode

+

+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:

+

+1. vmaBeginDefragmentationPass() function call:

+   - Calculates and returns the list of allocations to be moved in this pass.

+     Note this can be a time-consuming process.

+   - Reserves destination memory for them by creating temporary destination allocations

+     that you can query for their `VkDeviceMemory` + offset using vmaGetAllocationInfo().

+2. Inside the pass, **you should**:

+   - Inspect the returned list of allocations to be moved.

+   - Create new buffers/images and bind them at the returned destination temporary allocations.

+   - Copy data from source to destination resources if necessary.

+   - Destroy the source buffers/images, but NOT their allocations.

+3. vmaEndDefragmentationPass() function call:

+   - Frees the source memory reserved for the allocations that are moved.

+   - Modifies source #VmaAllocation objects that are moved to point to the destination reserved memory.

+   - Frees `VkDeviceMemory` blocks that became empty.

+

+Unlike in previous iterations of the defragmentation API, there is no list of "movable" allocations passed as a parameter.

+Defragmentation algorithm tries to move all suitable allocations.

+You can, however, refuse to move some of them inside a defragmentation pass, by setting

+`pass.pMoves[i].operation` to #VMA_DEFRAGMENTATION_MOVE_OPERATION_IGNORE.

+This is not recommended and may result in suboptimal packing of the allocations after defragmentation.

+If you cannot ensure any allocation can be moved, it is better to keep movable allocations separate in a custom pool.

+

+Inside a pass, for each allocation that should be moved:

+

+- You should copy its data from the source to the destination place by calling e.g. `vkCmdCopyBuffer()`, `vkCmdCopyImage()`.

+  - You need to make sure these commands finished executing before destroying the source buffers/images and before calling vmaEndDefragmentationPass().

+- If a resource doesn't contain any meaningful data, e.g. it is a transient color attachment image to be cleared,

+  filled, and used temporarily in each rendering frame, you can just recreate this image

+  without copying its data.

+- If the resource is in `HOST_VISIBLE` and `HOST_CACHED` memory, you can copy its data on the CPU

+  using `memcpy()`.

+- If you cannot move the allocation, you can set `pass.pMoves[i].operation` to #VMA_DEFRAGMENTATION_MOVE_OPERATION_IGNORE.

+  This will cancel the move.

+  - vmaEndDefragmentationPass() will then free the destination memory

+    not the source memory of the allocation, leaving it unchanged.

+- If you decide the allocation is unimportant and can be destroyed instead of moved (e.g. it wasn't used for long time),

+  you can set `pass.pMoves[i].operation` to #VMA_DEFRAGMENTATION_MOVE_OPERATION_DESTROY.

+  - vmaEndDefragmentationPass() will then free both source and destination memory, and will destroy the source #VmaAllocation object.

+

+You can defragment a specific custom pool by setting VmaDefragmentationInfo::pool

+(like in the example above) or all the default pools by setting this member to null.

+

+Defragmentation is always performed in each pool separately.

+Allocations are never moved between different Vulkan memory types.

+The size of the destination memory reserved for a moved allocation is the same as the original one.

+Alignment of an allocation as it was determined using `vkGetBufferMemoryRequirements()` etc. is also respected after defragmentation.

+Buffers/images should be recreated with the same `VkBufferCreateInfo` / `VkImageCreateInfo` parameters as the original ones.

+

+You can perform the defragmentation incrementally to limit the number of allocations and bytes to be moved

+in each pass, e.g. to call it in sync with render frames and not to experience too big hitches.

+See members: VmaDefragmentationInfo::maxBytesPerPass, VmaDefragmentationInfo::maxAllocationsPerPass.

+

+It is also safe to perform the defragmentation asynchronously to render frames and other Vulkan and VMA

+usage, possibly from multiple threads, with the exception that allocations

+returned in VmaDefragmentationPassMoveInfo::pMoves shouldn't be destroyed until the defragmentation pass is ended.

+

+<b>Mapping</b> is preserved on allocations that are moved during defragmentation.

+Whether through #VMA_ALLOCATION_CREATE_MAPPED_BIT or vmaMapMemory(), the allocations

+are mapped at their new place. Of course, pointer to the mapped data changes, so it needs to be queried

+using VmaAllocationInfo::pMappedData.

+

+\note Defragmentation is not supported in custom pools created with #VMA_POOL_CREATE_LINEAR_ALGORITHM_BIT.

+

+

+\page statistics Statistics

+

+This library contains several functions that return information about its internal state,

+especially the amount of memory allocated from Vulkan.

+

+\section statistics_numeric_statistics Numeric statistics

+

+If you need to obtain basic statistics about memory usage per heap, together with current budget,

+you can call function vmaGetHeapBudgets() and inspect structure #VmaBudget.

+This is useful to keep track of memory usage and stay withing budget

+(see also \ref staying_within_budget).

+Example:

+

+\code

+uint32_t heapIndex = ...

+

+VmaBudget budgets[VK_MAX_MEMORY_HEAPS];

+vmaGetHeapBudgets(allocator, budgets);

+

+printf("My heap currently has %u allocations taking %llu B,\n",

+    budgets[heapIndex].statistics.allocationCount,

+    budgets[heapIndex].statistics.allocationBytes);

+printf("allocated out of %u Vulkan device memory blocks taking %llu B,\n",

+    budgets[heapIndex].statistics.blockCount,

+    budgets[heapIndex].statistics.blockBytes);

+printf("Vulkan reports total usage %llu B with budget %llu B.\n",

+    budgets[heapIndex].usage,

+    budgets[heapIndex].budget);

+\endcode

+

+You can query for more detailed statistics per memory heap, type, and totals,

+including minimum and maximum allocation size and unused range size,

+by calling function vmaCalculateStatistics() and inspecting structure #VmaTotalStatistics.

+This function is slower though, as it has to traverse all the internal data structures,

+so it should be used only for debugging purposes.

+

+You can query for statistics of a custom pool using function vmaGetPoolStatistics()

+or vmaCalculatePoolStatistics().

+

+You can query for information about a specific allocation using function vmaGetAllocationInfo().

+It fill structure #VmaAllocationInfo.

+

+\section statistics_json_dump JSON dump

+

+You can dump internal state of the allocator to a string in JSON format using function vmaBuildStatsString().

+The result is guaranteed to be correct JSON.

+It uses ANSI encoding.

+Any strings provided by user (see [Allocation names](@ref allocation_names))

+are copied as-is and properly escaped for JSON, so if they use UTF-8, ISO-8859-2 or any other encoding,

+this JSON string can be treated as using this encoding.

+It must be freed using function vmaFreeStatsString().

+

+The format of this JSON string is not part of official documentation of the library,

+but it will not change in backward-incompatible way without increasing library major version number

+and appropriate mention in changelog.

+

+The JSON string contains all the data that can be obtained using vmaCalculateStatistics().

+It can also contain detailed map of allocated memory blocks and their regions -

+free and occupied by allocations.

+This allows e.g. to visualize the memory or assess fragmentation.

+

+

+\page allocation_annotation Allocation names and user data

+

+\section allocation_user_data Allocation user data

+

+You can annotate allocations with your own information, e.g. for debugging purposes.

+To do that, fill VmaAllocationCreateInfo::pUserData field when creating

+an allocation. It is an opaque `void*` pointer. You can use it e.g. as a pointer,

+some handle, index, key, ordinal number or any other value that would associate

+the allocation with your custom metadata.

+It it useful to identify appropriate data structures in your engine given #VmaAllocation,

+e.g. when doing \ref defragmentation.

+

+\code

+VkBufferCreateInfo bufCreateInfo = ...

+

+MyBufferMetadata* pMetadata = CreateBufferMetadata();

+

+VmaAllocationCreateInfo allocCreateInfo = {};

+allocCreateInfo.usage = VMA_MEMORY_USAGE_AUTO;

+allocCreateInfo.pUserData = pMetadata;

+

+VkBuffer buffer;

+VmaAllocation allocation;

+vmaCreateBuffer(allocator, &bufCreateInfo, &allocCreateInfo, &buffer, &allocation, nullptr);

+\endcode

+

+The pointer may be later retrieved as VmaAllocationInfo::pUserData:

+

+\code

+VmaAllocationInfo allocInfo;

+vmaGetAllocationInfo(allocator, allocation, &allocInfo);

+MyBufferMetadata* pMetadata = (MyBufferMetadata*)allocInfo.pUserData;

+\endcode

+

+It can also be changed using function vmaSetAllocationUserData().

+

+Values of (non-zero) allocations' `pUserData` are printed in JSON report created by

+vmaBuildStatsString() in hexadecimal form.

+

+\section allocation_names Allocation names

+

+An allocation can also carry a null-terminated string, giving a name to the allocation.

+To set it, call vmaSetAllocationName().

+The library creates internal copy of the string, so the pointer you pass doesn't need

+to be valid for whole lifetime of the allocation. You can free it after the call.

+

+\code

+std::string imageName = "Texture: ";

+imageName += fileName;

+vmaSetAllocationName(allocator, allocation, imageName.c_str());

+\endcode

+

+The string can be later retrieved by inspecting VmaAllocationInfo::pName.

+It is also printed in JSON report created by vmaBuildStatsString().

+

+\note Setting string name to VMA allocation doesn't automatically set it to the Vulkan buffer or image created with it.

+You must do it manually using an extension like VK_EXT_debug_utils, which is independent of this library.

+

+

+\page virtual_allocator Virtual allocator

+

+As an extra feature, the core allocation algorithm of the library is exposed through a simple and convenient API of "virtual allocator".

+It doesn't allocate any real GPU memory. It just keeps track of used and free regions of a "virtual block".

+You can use it to allocate your own memory or other objects, even completely unrelated to Vulkan.

+A common use case is sub-allocation of pieces of one large GPU buffer.

+

+\section virtual_allocator_creating_virtual_block Creating virtual block

+

+To use this functionality, there is no main "allocator" object.

+You don't need to have #VmaAllocator object created.

+All you need to do is to create a separate #VmaVirtualBlock object for each block of memory you want to be managed by the allocator:

+

+-# Fill in #VmaVirtualBlockCreateInfo structure.

+-# Call vmaCreateVirtualBlock(). Get new #VmaVirtualBlock object.

+

+Example:

+

+\code

+VmaVirtualBlockCreateInfo blockCreateInfo = {};

+blockCreateInfo.size = 1048576; // 1 MB

+

+VmaVirtualBlock block;

+VkResult res = vmaCreateVirtualBlock(&blockCreateInfo, &block);

+\endcode

+

+\section virtual_allocator_making_virtual_allocations Making virtual allocations

+

+#VmaVirtualBlock object contains internal data structure that keeps track of free and occupied regions

+using the same code as the main Vulkan memory allocator.

+Similarly to #VmaAllocation for standard GPU allocations, there is #VmaVirtualAllocation type

+that represents an opaque handle to an allocation withing the virtual block.

+

+In order to make such allocation:

+

+-# Fill in #VmaVirtualAllocationCreateInfo structure.

+-# Call vmaVirtualAllocate(). Get new #VmaVirtualAllocation object that represents the allocation.

+   You can also receive `VkDeviceSize offset` that was assigned to the allocation.

+

+Example:

+

+\code

+VmaVirtualAllocationCreateInfo allocCreateInfo = {};

+allocCreateInfo.size = 4096; // 4 KB

+

+VmaVirtualAllocation alloc;

+VkDeviceSize offset;

+res = vmaVirtualAllocate(block, &allocCreateInfo, &alloc, &offset);

+if(res == VK_SUCCESS)

+{

+    // Use the 4 KB of your memory starting at offset.

+}

+else

+{

+    // Allocation failed - no space for it could be found. Handle this error!

+}

+\endcode

+

+\section virtual_allocator_deallocation Deallocation

+

+When no longer needed, an allocation can be freed by calling vmaVirtualFree().

+You can only pass to this function an allocation that was previously returned by vmaVirtualAllocate()

+called for the same #VmaVirtualBlock.

+

+When whole block is no longer needed, the block object can be released by calling vmaDestroyVirtualBlock().

+All allocations must be freed before the block is destroyed, which is checked internally by an assert.

+However, if you don't want to call vmaVirtualFree() for each allocation, you can use vmaClearVirtualBlock() to free them all at once -

+a feature not available in normal Vulkan memory allocator. Example:

+

+\code

+vmaVirtualFree(block, alloc);

+vmaDestroyVirtualBlock(block);

+\endcode

+

+\section virtual_allocator_allocation_parameters Allocation parameters

+

+You can attach a custom pointer to each allocation by using vmaSetVirtualAllocationUserData().

+Its default value is null.

+It can be used to store any data that needs to be associated with that allocation - e.g. an index, a handle, or a pointer to some

+larger data structure containing more information. Example:

+

+\code

+struct CustomAllocData

+{

+    std::string m_AllocName;

+};

+CustomAllocData* allocData = new CustomAllocData();

+allocData->m_AllocName = "My allocation 1";

+vmaSetVirtualAllocationUserData(block, alloc, allocData);

+\endcode

+

+The pointer can later be fetched, along with allocation offset and size, by passing the allocation handle to function

+vmaGetVirtualAllocationInfo() and inspecting returned structure #VmaVirtualAllocationInfo.

+If you allocated a new object to be used as the custom pointer, don't forget to delete that object before freeing the allocation!

+Example:

+

+\code

+VmaVirtualAllocationInfo allocInfo;

+vmaGetVirtualAllocationInfo(block, alloc, &allocInfo);

+delete (CustomAllocData*)allocInfo.pUserData;

+

+vmaVirtualFree(block, alloc);

+\endcode

+

+\section virtual_allocator_alignment_and_units Alignment and units

+

+It feels natural to express sizes and offsets in bytes.

+If an offset of an allocation needs to be aligned to a multiply of some number (e.g. 4 bytes), you can fill optional member

+VmaVirtualAllocationCreateInfo::alignment to request it. Example:

+

+\code

+VmaVirtualAllocationCreateInfo allocCreateInfo = {};

+allocCreateInfo.size = 4096; // 4 KB

+allocCreateInfo.alignment = 4; // Returned offset must be a multiply of 4 B

+

+VmaVirtualAllocation alloc;

+res = vmaVirtualAllocate(block, &allocCreateInfo, &alloc, nullptr);

+\endcode

+

+Alignments of different allocations made from one block may vary.

+However, if all alignments and sizes are always multiply of some size e.g. 4 B or `sizeof(MyDataStruct)`,

+you can express all sizes, alignments, and offsets in multiples of that size instead of individual bytes.

+It might be more convenient, but you need to make sure to use this new unit consistently in all the places:

+

+- VmaVirtualBlockCreateInfo::size

+- VmaVirtualAllocationCreateInfo::size and VmaVirtualAllocationCreateInfo::alignment

+- Using offset returned by vmaVirtualAllocate() or in VmaVirtualAllocationInfo::offset

+

+\section virtual_allocator_statistics Statistics

+

+You can obtain statistics of a virtual block using vmaGetVirtualBlockStatistics()

+(to get brief statistics that are fast to calculate)

+or vmaCalculateVirtualBlockStatistics() (to get more detailed statistics, slower to calculate).

+The functions fill structures #VmaStatistics, #VmaDetailedStatistics respectively - same as used by the normal Vulkan memory allocator.

+Example:

+

+\code

+VmaStatistics stats;

+vmaGetVirtualBlockStatistics(block, &stats);

+printf("My virtual block has %llu bytes used by %u virtual allocations\n",

+    stats.allocationBytes, stats.allocationCount);

+\endcode

+

+You can also request a full list of allocations and free regions as a string in JSON format by calling

+vmaBuildVirtualBlockStatsString().

+Returned string must be later freed using vmaFreeVirtualBlockStatsString().

+The format of this string differs from the one returned by the main Vulkan allocator, but it is similar.

+

+\section virtual_allocator_additional_considerations Additional considerations

+

+The "virtual allocator" functionality is implemented on a level of individual memory blocks.

+Keeping track of a whole collection of blocks, allocating new ones when out of free space,

+deleting empty ones, and deciding which one to try first for a new allocation must be implemented by the user.

+

+Alternative allocation algorithms are supported, just like in custom pools of the real GPU memory.

+See enum #VmaVirtualBlockCreateFlagBits to learn how to specify them (e.g. #VMA_VIRTUAL_BLOCK_CREATE_LINEAR_ALGORITHM_BIT).

+You can find their description in chapter \ref custom_memory_pools.

+Allocation strategies are also supported.

+See enum #VmaVirtualAllocationCreateFlagBits to learn how to specify them (e.g. #VMA_VIRTUAL_ALLOCATION_CREATE_STRATEGY_MIN_TIME_BIT).

+

+Following features are supported only by the allocator of the real GPU memory and not by virtual allocations:

+buffer-image granularity, `VMA_DEBUG_MARGIN`, `VMA_MIN_ALIGNMENT`.

+

+

+\page debugging_memory_usage Debugging incorrect memory usage

+

+If you suspect a bug with memory usage, like usage of uninitialized memory or

+memory being overwritten out of bounds of an allocation,

+you can use debug features of this library to verify this.

+

+\section debugging_memory_usage_initialization Memory initialization

+

+If you experience a bug with incorrect and nondeterministic data in your program and you suspect uninitialized memory to be used,

+you can enable automatic memory initialization to verify this.

+To do it, define macro `VMA_DEBUG_INITIALIZE_ALLOCATIONS` to 1.

+

+\code

+#define VMA_DEBUG_INITIALIZE_ALLOCATIONS 1

+#include "vk_mem_alloc.h"

+\endcode

+

+It makes memory of new allocations initialized to bit pattern `0xDCDCDCDC`.

+Before an allocation is destroyed, its memory is filled with bit pattern `0xEFEFEFEF`.

+Memory is automatically mapped and unmapped if necessary.

+

+If you find these values while debugging your program, good chances are that you incorrectly

+read Vulkan memory that is allocated but not initialized, or already freed, respectively.

+

+Memory initialization works only with memory types that are `HOST_VISIBLE` and with allocations that can be mapped.

+It works also with dedicated allocations.

+

+\section debugging_memory_usage_margins Margins

+

+By default, allocations are laid out in memory blocks next to each other if possible

+(considering required alignment, `bufferImageGranularity`, and `nonCoherentAtomSize`).

+

+![Allocations without margin](../gfx/Margins_1.png)

+

+Define macro `VMA_DEBUG_MARGIN` to some non-zero value (e.g. 16) to enforce specified

+number of bytes as a margin after every allocation.

+

+\code

+#define VMA_DEBUG_MARGIN 16

+#include "vk_mem_alloc.h"

+\endcode

+

+![Allocations with margin](../gfx/Margins_2.png)

+

+If your bug goes away after enabling margins, it means it may be caused by memory

+being overwritten outside of allocation boundaries. It is not 100% certain though.

+Change in application behavior may also be caused by different order and distribution

+of allocations across memory blocks after margins are applied.

+

+Margins work with all types of memory.

+

+Margin is applied only to allocations made out of memory blocks and not to dedicated

+allocations, which have their own memory block of specific size.

+It is thus not applied to allocations made using #VMA_ALLOCATION_CREATE_DEDICATED_MEMORY_BIT flag

+or those automatically decided to put into dedicated allocations, e.g. due to its

+large size or recommended by VK_KHR_dedicated_allocation extension.

+

+Margins appear in [JSON dump](@ref statistics_json_dump) as part of free space.

+

+Note that enabling margins increases memory usage and fragmentation.

+

+Margins do not apply to \ref virtual_allocator.

+

+\section debugging_memory_usage_corruption_detection Corruption detection

+

+You can additionally define macro `VMA_DEBUG_DETECT_CORRUPTION` to 1 to enable validation

+of contents of the margins.

+

+\code

+#define VMA_DEBUG_MARGIN 16

+#define VMA_DEBUG_DETECT_CORRUPTION 1

+#include "vk_mem_alloc.h"

+\endcode

+

+When this feature is enabled, number of bytes specified as `VMA_DEBUG_MARGIN`

+(it must be multiply of 4) after every allocation is filled with a magic number.

+This idea is also know as "canary".

+Memory is automatically mapped and unmapped if necessary.

+

+This number is validated automatically when the allocation is destroyed.

+If it is not equal to the expected value, `VMA_ASSERT()` is executed.

+It clearly means that either CPU or GPU overwritten the memory outside of boundaries of the allocation,

+which indicates a serious bug.

+

+You can also explicitly request checking margins of all allocations in all memory blocks

+that belong to specified memory types by using function vmaCheckCorruption(),

+or in memory blocks that belong to specified custom pool, by using function

+vmaCheckPoolCorruption().

+

+Margin validation (corruption detection) works only for memory types that are

+`HOST_VISIBLE` and `HOST_COHERENT`.

+

+

+\page opengl_interop OpenGL Interop

+

+VMA provides some features that help with interoperability with OpenGL.

+

+\section opengl_interop_exporting_memory Exporting memory

+

+If you want to attach `VkExportMemoryAllocateInfoKHR` structure to `pNext` chain of memory allocations made by the library:

+

+It is recommended to create \ref custom_memory_pools for such allocations.

+Define and fill in your `VkExportMemoryAllocateInfoKHR` structure and attach it to VmaPoolCreateInfo::pMemoryAllocateNext

+while creating the custom pool.

+Please note that the structure must remain alive and unchanged for the whole lifetime of the #VmaPool,

+not only while creating it, as no copy of the structure is made,

+but its original pointer is used for each allocation instead.

+

+If you want to export all memory allocated by the library 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.

+Please note that new versions of the library also support dedicated allocations created in custom pools.

+

+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`.

+

+

+\section opengl_interop_custom_alignment Custom alignment

+

+Buffers or images exported to a different API like OpenGL may require a different alignment,

+higher than the one used by the library automatically, queried from functions like `vkGetBufferMemoryRequirements`.

+To impose such alignment:

+

+It is recommended to create \ref custom_memory_pools for such allocations.

+Set VmaPoolCreateInfo::minAllocationAlignment member to the minimum alignment required for each allocation

+to be made out of this pool.

+The alignment actually used will be the maximum of this member and the alignment returned for the specific buffer or image

+from a function like `vkGetBufferMemoryRequirements`, which is called by VMA automatically.

+

+If you want to create a buffer with a specific minimum alignment out of default pools,

+use special function vmaCreateBufferWithAlignment(), which takes additional parameter `minAlignment`.

+

+Note the problem of alignment affects only resources placed inside bigger `VkDeviceMemory` blocks and not dedicated

+allocations, as these, by definition, always have alignment = 0 because the resource is bound to the beginning of its dedicated block.

+Contrary to Direct3D 12, Vulkan doesn't have a concept of alignment of the entire memory block passed on its allocation.

+

+

+\page usage_patterns Recommended usage patterns

+

+Vulkan gives great flexibility in memory allocation.

+This chapter shows the most common patterns.

+<b>When:</b>

+Any resources that you frequently write and read on GPU,

+e.g. images used as color attachments (aka "render targets"), depth-stencil attachments,

+images/buffers used as storage image/buffer (aka "Unordered Access View (UAV)").

+

+<b>What to do:</b>

+Let the library select the optimal memory type, which will likely have `VK_MEMORY_PROPERTY_DEVICE_LOCAL_BIT`.

+

+\code

+VkImageCreateInfo imgCreateInfo = { VK_STRUCTURE_TYPE_IMAGE_CREATE_INFO };

+imgCreateInfo.imageType = VK_IMAGE_TYPE_2D;

+<b>Also consider:</b>

+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.

+\section usage_patterns_advanced_data_uploading Advanced data uploading

+

+For resources that you frequently write on CPU via mapped pointer and

+freqnently read on GPU e.g. as a uniform buffer (also called "dynamic"), multiple options are possible:

+

+-# Easiest solution is to have one copy of the resource in `HOST_VISIBLE` memory,

+   even if it means system RAM (not `DEVICE_LOCAL`) on systems with a discrete graphics card,

+   and make the device reach out to that resource directly.

+   - Reads performed by the device will then go through PCI Express bus.

+     The performace of this access may be limited, but it may be fine depending on the size

+     of this resource (whether it is small enough to quickly end up in GPU cache) and the sparsity

+     of access.

+-# On systems with unified memory (e.g. AMD APU or Intel integrated graphics, mobile chips),

+   a memory type may be available that is both `HOST_VISIBLE` (available for mapping) and `DEVICE_LOCAL`

+   (fast to access from the GPU). Then, it is likely the best choice for such type of resource.

+-# Systems with a discrete graphics card and separate video memory may or may not expose

+   a memory type that is both `HOST_VISIBLE` and `DEVICE_LOCAL`, also known as Base Address Register (BAR).

+   If they do, it represents a piece of VRAM (or entire VRAM, if ReBAR is enabled in the motherboard BIOS)

+   that is available to CPU for mapping.

+   - Writes performed by the host to that memory go through PCI Express bus.

+     The performance of these writes may be limited, but it may be fine, especially on PCIe 4.0,

+     as long as rules of using uncached and write-combined memory are followed - only sequential writes and no reads.

+-# Finally, you may need or prefer to create a separate copy of the resource in `DEVICE_LOCAL` memory,

+   a separate "staging" copy in `HOST_VISIBLE` memory and perform an explicit transfer command between them.

+

+Thankfully, VMA offers an aid to create and use such resources in the the way optimal

+for the current Vulkan device. To help the library make the best choice,

+use flag #VMA_ALLOCATION_CREATE_HOST_ACCESS_SEQUENTIAL_WRITE_BIT together with

+#VMA_ALLOCATION_CREATE_HOST_ACCESS_ALLOW_TRANSFER_INSTEAD_BIT.

+It will then prefer a memory type that is both `DEVICE_LOCAL` and `HOST_VISIBLE` (integrated memory or BAR),

+but if no such memory type is available or allocation from it fails

+(PC graphics cards have only 256 MB of BAR by default, unless ReBAR is supported and enabled in BIOS),

+it will fall back to `DEVICE_LOCAL` memory for fast GPU access.

+It is then up to you to detect that the allocation ended up in a memory type that is not `HOST_VISIBLE`,

+so you need to create another "staging" allocation and perform explicit transfers.

+

+\section usage_patterns_other_use_cases Other use cases

+

+Here are some other, less obvious use cases and their recommended settings:

+

+- An image that is used only as transfer source and destination, but it should stay on the device,

+  as it is used to temporarily store a copy of some texture, e.g. from the current to the next frame,

+  for temporal antialiasing or other temporal effects.

+  - Use `VkImageCreateInfo::usage = VK_IMAGE_USAGE_TRANSFER_SRC_BIT | VK_IMAGE_USAGE_TRANSFER_DST_BIT`

+  - Use VmaAllocationCreateInfo::usage = #VMA_MEMORY_USAGE_AUTO

+- An image that is used only as transfer source and destination, but it should be placed

+  in the system RAM despite it doesn't need to be mapped, because it serves as a "swap" copy to evict

+  least recently used textures from VRAM.

+  - Use `VkImageCreateInfo::usage = VK_IMAGE_USAGE_TRANSFER_SRC_BIT | VK_IMAGE_USAGE_TRANSFER_DST_BIT`

+  - Use VmaAllocationCreateInfo::usage = #VMA_MEMORY_USAGE_AUTO_PREFER_HOST,

+    as VMA needs a hint here to differentiate from the previous case.

+- A buffer that you want to map and write from the CPU, directly read from the GPU

+  (e.g. as a uniform or vertex buffer), but you have a clear preference to place it in device or

+  host memory due to its large size.

+  - Use `VkBufferCreateInfo::usage = VK_BUFFER_USAGE_UNIFORM_BUFFER_BIT`

+  - Use VmaAllocationCreateInfo::usage = #VMA_MEMORY_USAGE_AUTO_PREFER_DEVICE or #VMA_MEMORY_USAGE_AUTO_PREFER_HOST

+  - Use VmaAllocationCreateInfo::flags = #VMA_ALLOCATION_CREATE_HOST_ACCESS_SEQUENTIAL_WRITE_BIT

+

+

+\page configuration Configuration

+

+Please check "CONFIGURATION SECTION" in the code to find macros that you can define

+before each include of this file or change directly in this file to provide

+your own implementation of basic facilities like assert, `min()` and `max()` functions,

+mutex, atomic etc.

+The library uses its own implementation of containers by default, but you can switch to using

+STL containers instead.

+

+For example, define `VMA_ASSERT(expr)` before including the library to provide

+custom implementation of the assertion, compatible with your project.

+By default it is defined to standard C `assert(expr)` in `_DEBUG` configuration

+and empty otherwise.

+

+\section config_Vulkan_functions Pointers to Vulkan functions

+

+There are multiple ways to import pointers to Vulkan functions in the library.

+In the simplest case you don't need to do anything.

+If the compilation or linking of your program or the initialization of the #VmaAllocator

+doesn't work for you, you can try to reconfigure it.

+

+First, the allocator tries to fetch pointers to Vulkan functions linked statically,

+like this:

+

+\code

+m_VulkanFunctions.vkAllocateMemory = (PFN_vkAllocateMemory)vkAllocateMemory;

+\endcode

+

+If you want to disable this feature, set configuration macro: `#define VMA_STATIC_VULKAN_FUNCTIONS 0`.

+

+Second, you can provide the pointers yourself by setting member VmaAllocatorCreateInfo::pVulkanFunctions.

+You can fetch them e.g. using functions `vkGetInstanceProcAddr` and `vkGetDeviceProcAddr` or

+by using a helper library like [volk](https://github.com/zeux/volk).

+

+Third, VMA tries to fetch remaining pointers that are still null by calling

+`vkGetInstanceProcAddr` and `vkGetDeviceProcAddr` on its own.

+You need to only fill in VmaVulkanFunctions::vkGetInstanceProcAddr and VmaVulkanFunctions::vkGetDeviceProcAddr.

+Other pointers will be fetched automatically.

+If you want to disable this feature, set configuration macro: `#define VMA_DYNAMIC_VULKAN_FUNCTIONS 0`.

+

+Finally, all the function pointers required by the library (considering selected

+Vulkan version and enabled extensions) are checked with `VMA_ASSERT` if they are not null.

+

+

+\section custom_memory_allocator Custom host memory allocator

+

+If you use custom allocator for CPU memory rather than default operator `new`

+and `delete` from C++, you can make this library using your allocator as well

+by filling optional member VmaAllocatorCreateInfo::pAllocationCallbacks. These

+functions will be passed to Vulkan, as well as used by the library itself to

+make any CPU-side allocations.

+

+\section allocation_callbacks Device memory allocation callbacks

+

+The library makes calls to `vkAllocateMemory()` and `vkFreeMemory()` internally.

+You can setup callbacks to be informed about these calls, e.g. for the purpose

+of gathering some statistics. To do it, fill optional member

+VmaAllocatorCreateInfo::pDeviceMemoryCallbacks.

+

+\section heap_memory_limit Device heap memory limit

+

+When device memory of certain heap runs out of free space, new allocations may

+fail (returning error code) or they may succeed, silently pushing some existing_

+memory blocks from GPU VRAM to system RAM (which degrades performance). This

+behavior is implementation-dependent - it depends on GPU vendor and graphics

+driver.

+

+On AMD cards it can be controlled while creating Vulkan device object by using

+VK_AMD_memory_overallocation_behavior extension, if available.

+

+Alternatively, if you want to test how your program behaves with limited amount of Vulkan device

+memory available without switching your graphics card to one that really has

+smaller VRAM, you can use a feature of this library intended for this purpose.

+To do it, fill optional member VmaAllocatorCreateInfo::pHeapSizeLimit.

+

+

+

+\page vk_khr_dedicated_allocation VK_KHR_dedicated_allocation

+

+VK_KHR_dedicated_allocation is a Vulkan extension which can be used to improve

+performance on some GPUs. It augments Vulkan API with possibility to query

+driver whether it prefers particular buffer or image to have its own, dedicated

+allocation (separate `VkDeviceMemory` block) for better efficiency - to be able

+to do some internal optimizations. The extension is supported by this library.

+It will be used automatically when enabled.

+

+It has been promoted to core Vulkan 1.1, so if you use eligible Vulkan version

+and inform VMA about it by setting VmaAllocatorCreateInfo::vulkanApiVersion,

+you are all set.

+

+Otherwise, if you want to use it as an extension:

+

+1 . When creating Vulkan device, check if following 2 device extensions are

+supported (call `vkEnumerateDeviceExtensionProperties()`).

+If yes, enable them (fill `VkDeviceCreateInfo::ppEnabledExtensionNames`).

+

+- VK_KHR_get_memory_requirements2

+- VK_KHR_dedicated_allocation

+

+If you enabled these extensions:

+

+2 . Use #VMA_ALLOCATOR_CREATE_KHR_DEDICATED_ALLOCATION_BIT flag when creating

+your #VmaAllocator to inform the library that you enabled required extensions

+and you want the library to use them.

+

+\code

+allocatorInfo.flags |= VMA_ALLOCATOR_CREATE_KHR_DEDICATED_ALLOCATION_BIT;

+

+vmaCreateAllocator(&allocatorInfo, &allocator);

+\endcode

+

+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._

+

+It is OK, you should just ignore it. It happens because you use function

+`vkGetBufferMemoryRequirements2KHR()` instead of standard

+`vkGetBufferMemoryRequirements()`, while the validation layer seems to be

+unaware of it.

+

+To learn more about this extension, see:

+

+- [VK_KHR_dedicated_allocation in Vulkan specification](https://www.khronos.org/registry/vulkan/specs/1.2-extensions/html/chap50.html#VK_KHR_dedicated_allocation)

+

+

+\page vk_ext_memory_priority VK_EXT_memory_priority

+

+VK_EXT_memory_priority is a device extension that allows to pass additional "priority"

+value to Vulkan memory allocations that the implementation may use prefer certain

+buffers and images that are critical for performance to stay in device-local memory

+in cases when the memory is over-subscribed, while some others may be moved to the system memory.

+

+VMA offers convenient usage of this extension.

+If you enable it, you can pass "priority" parameter when creating allocations or custom pools

+and the library automatically passes the value to Vulkan using this extension.

+

+If you want to use this extension in connection with VMA, follow these steps:

+

+\section vk_ext_memory_priority_initialization Initialization

+

+1) Call `vkEnumerateDeviceExtensionProperties` for the physical device.

+Check if the extension is supported - if returned array of `VkExtensionProperties` contains "VK_EXT_memory_priority".

+

+2) Call `vkGetPhysicalDeviceFeatures2` for the physical device instead of old `vkGetPhysicalDeviceFeatures`.

+Attach additional structure `VkPhysicalDeviceMemoryPriorityFeaturesEXT` to `VkPhysicalDeviceFeatures2::pNext` to be returned.

+Check if the device feature is really supported - check if `VkPhysicalDeviceMemoryPriorityFeaturesEXT::memoryPriority` is true.

+

+3) While creating device with `vkCreateDevice`, enable this extension - add "VK_EXT_memory_priority"

+to the list passed as `VkDeviceCreateInfo::ppEnabledExtensionNames`.

+

+4) While creating the device, also don't set `VkDeviceCreateInfo::pEnabledFeatures`.

+Fill in `VkPhysicalDeviceFeatures2` structure instead and pass it as `VkDeviceCreateInfo::pNext`.

+Enable this device feature - attach additional structure `VkPhysicalDeviceMemoryPriorityFeaturesEXT` to

+`VkPhysicalDeviceFeatures2::pNext` chain and set its member `memoryPriority` to `VK_TRUE`.

+

+5) While creating #VmaAllocator with vmaCreateAllocator() inform VMA that you

+have enabled this extension and feature - add #VMA_ALLOCATOR_CREATE_EXT_MEMORY_PRIORITY_BIT

+to VmaAllocatorCreateInfo::flags.

+

+\section vk_ext_memory_priority_usage Usage

+

+When using this extension, you should initialize following member:

+

+- VmaAllocationCreateInfo::priority when creating a dedicated allocation with #VMA_ALLOCATION_CREATE_DEDICATED_MEMORY_BIT.

+- VmaPoolCreateInfo::priority when creating a custom pool.

+

+It should be a floating-point value between `0.0f` and `1.0f`, where recommended default is `0.5f`.

+Memory allocated with higher value can be treated by the Vulkan implementation as higher priority

+and so it can have lower chances of being pushed out to system memory, experiencing degraded performance.

+

+It might be a good idea to create performance-critical resources like color-attachment or depth-stencil images

+as dedicated and set high priority to them. For example:

+

+\code

+VkImageCreateInfo imgCreateInfo = { VK_STRUCTURE_TYPE_IMAGE_CREATE_INFO };

+imgCreateInfo.imageType = VK_IMAGE_TYPE_2D;

+imgCreateInfo.extent.width = 3840;

+imgCreateInfo.extent.height = 2160;

+imgCreateInfo.extent.depth = 1;

+imgCreateInfo.mipLevels = 1;

+imgCreateInfo.arrayLayers = 1;

+imgCreateInfo.format = VK_FORMAT_R8G8B8A8_UNORM;

+imgCreateInfo.tiling = VK_IMAGE_TILING_OPTIMAL;

+imgCreateInfo.initialLayout = VK_IMAGE_LAYOUT_UNDEFINED;

+imgCreateInfo.usage = VK_IMAGE_USAGE_SAMPLED_BIT | VK_IMAGE_USAGE_COLOR_ATTACHMENT_BIT;

+imgCreateInfo.samples = VK_SAMPLE_COUNT_1_BIT;

+

+VmaAllocationCreateInfo allocCreateInfo = {};

+allocCreateInfo.usage = VMA_MEMORY_USAGE_AUTO;

+allocCreateInfo.flags = VMA_ALLOCATION_CREATE_DEDICATED_MEMORY_BIT;

+allocCreateInfo.priority = 1.0f;

+

+VkImage img;

+VmaAllocation alloc;

+vmaCreateImage(allocator, &imgCreateInfo, &allocCreateInfo, &img, &alloc, nullptr);

+\endcode

+

+`priority` member is ignored in the following situations:

+

+- Allocations created in custom pools: They inherit the priority, along with all other allocation parameters

+  from the parametrs passed in #VmaPoolCreateInfo when the pool was created.

+- Allocations created in default pools: They inherit the priority from the parameters

+  VMA used when creating default pools, which means `priority == 0.5f`.

+

+

+\page vk_amd_device_coherent_memory VK_AMD_device_coherent_memory

+

+VK_AMD_device_coherent_memory is a device extension that enables access to

+additional memory types with `VK_MEMORY_PROPERTY_DEVICE_COHERENT_BIT_AMD` and

+`VK_MEMORY_PROPERTY_DEVICE_UNCACHED_BIT_AMD` flag. It is useful mostly for

+allocation of buffers intended for writing "breadcrumb markers" in between passes

+or draw calls, which in turn are useful for debugging GPU crash/hang/TDR cases.

+

+When the extension is available but has not been enabled, Vulkan physical device

+still exposes those memory types, but their usage is forbidden. VMA automatically

+takes care of that - it returns `VK_ERROR_FEATURE_NOT_PRESENT` when an attempt

+to allocate memory of such type is made.

+

+If you want to use this extension in connection with VMA, follow these steps:

+

+\section vk_amd_device_coherent_memory_initialization Initialization

+

+1) Call `vkEnumerateDeviceExtensionProperties` for the physical device.

+Check if the extension is supported - if returned array of `VkExtensionProperties` contains "VK_AMD_device_coherent_memory".

+

+2) Call `vkGetPhysicalDeviceFeatures2` for the physical device instead of old `vkGetPhysicalDeviceFeatures`.

+Attach additional structure `VkPhysicalDeviceCoherentMemoryFeaturesAMD` to `VkPhysicalDeviceFeatures2::pNext` to be returned.

+Check if the device feature is really supported - check if `VkPhysicalDeviceCoherentMemoryFeaturesAMD::deviceCoherentMemory` is true.

+

+3) While creating device with `vkCreateDevice`, enable this extension - add "VK_AMD_device_coherent_memory"

+to the list passed as `VkDeviceCreateInfo::ppEnabledExtensionNames`.

+

+4) While creating the device, also don't set `VkDeviceCreateInfo::pEnabledFeatures`.

+Fill in `VkPhysicalDeviceFeatures2` structure instead and pass it as `VkDeviceCreateInfo::pNext`.

+Enable this device feature - attach additional structure `VkPhysicalDeviceCoherentMemoryFeaturesAMD` to

+`VkPhysicalDeviceFeatures2::pNext` and set its member `deviceCoherentMemory` to `VK_TRUE`.

+

+5) While creating #VmaAllocator with vmaCreateAllocator() inform VMA that you

+have enabled this extension and feature - add #VMA_ALLOCATOR_CREATE_AMD_DEVICE_COHERENT_MEMORY_BIT

+to VmaAllocatorCreateInfo::flags.

+

+\section vk_amd_device_coherent_memory_usage Usage

+

+After following steps described above, you can create VMA allocations and custom pools

+out of the special `DEVICE_COHERENT` and `DEVICE_UNCACHED` memory types on eligible

+devices. There are multiple ways to do it, for example:

+

+- You can request or prefer to allocate out of such memory types by adding

+  `VK_MEMORY_PROPERTY_DEVICE_UNCACHED_BIT_AMD` to VmaAllocationCreateInfo::requiredFlags

+  or VmaAllocationCreateInfo::preferredFlags. Those flags can be freely mixed with

+  other ways of \ref choosing_memory_type, like setting VmaAllocationCreateInfo::usage.

+- If you manually found memory type index to use for this purpose, force allocation

+  from this specific index by setting VmaAllocationCreateInfo::memoryTypeBits `= 1u << index`.

+\section enabling_buffer_device_address_initialization Initialization

+

+1) (For Vulkan version < 1.2) Call `vkEnumerateDeviceExtensionProperties` for the physical device.

+

+\page general_considerations General considerations

+

+\section general_considerations_thread_safety Thread safety

+

+- The library has no global state, so separate #VmaAllocator objects can be used

+  independently.

+  There should be no need to create multiple such objects though - one per `VkDevice` is enough.

+- By default, all calls to functions that take #VmaAllocator as first parameter

+  are safe to call from multiple threads simultaneously because they are

+  synchronized internally when needed.

+  This includes allocation and deallocation from default memory pool, as well as custom #VmaPool.

+- When the allocator is created with #VMA_ALLOCATOR_CREATE_EXTERNALLY_SYNCHRONIZED_BIT

+  flag, calls to functions that take such #VmaAllocator object must be

+  synchronized externally.

+- Access to a #VmaAllocation object must be externally synchronized. For example,

+  you must not call vmaGetAllocationInfo() and vmaMapMemory() from different

+  threads at the same time if you pass the same #VmaAllocation object to these

+  functions.

+- #VmaVirtualBlock is not safe to be used from multiple threads simultaneously.

+

+\section general_considerations_versioning_and_compatibility Versioning and compatibility

+

+The library uses [**Semantic Versioning**](https://semver.org/),

+which means version numbers follow convention: Major.Minor.Patch (e.g. 2.3.0), where:

+

+- Incremented Patch version means a release is backward- and forward-compatible,

+  introducing only some internal improvements, bug fixes, optimizations etc.

+  or changes that are out of scope of the official API described in this documentation.

+- Incremented Minor version means a release is backward-compatible,

+  so existing code that uses the library should continue to work, while some new

+  symbols could have been added: new structures, functions, new values in existing

+  enums and bit flags, new structure members, but not new function parameters.

+- Incrementing Major version means a release could break some backward compatibility.

+

+All changes between official releases are documented in file "CHANGELOG.md".

+

+\warning Backward compatiblity is considered on the level of C++ source code, not binary linkage.

+Adding new members to existing structures is treated as backward compatible if initializing

+the new members to binary zero results in the old behavior.

+You should always fully initialize all library structures to zeros and not rely on their

+exact binary size.

+

+\section general_considerations_validation_layer_warnings Validation layer warnings

+

+When using this library, you can meet following types of warnings issued by

+Vulkan validation layer. They don't necessarily indicate a bug, so you may need

+to just ignore them.

+

+- *vkBindBufferMemory(): Binding memory to buffer 0xeb8e4 but vkGetBufferMemoryRequirements() has not been called on that buffer.*

+  - It happens when VK_KHR_dedicated_allocation extension is enabled.

+    `vkGetBufferMemoryRequirements2KHR` function is used instead, while validation layer seems to be unaware of it.

+- *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.

+- *Non-linear image 0xebc91 is aliased with linear buffer 0xeb8e4 which may indicate a bug.*

+  - It may happen when you use [defragmentation](@ref defragmentation).

+

+\section general_considerations_allocation_algorithm Allocation algorithm

+

+The library uses following algorithm for allocation, in order:

+

+-# Try to find free range of memory in existing blocks.

+-# If failed, try to create a new block of `VkDeviceMemory`, with preferred block size.

+-# If failed, try to create such block with size / 2, size / 4, size / 8.

+-# If failed, try to allocate separate `VkDeviceMemory` for this allocation,

+   just like when you use #VMA_ALLOCATION_CREATE_DEDICATED_MEMORY_BIT.

+-# If failed, choose other memory type that meets the requirements specified in

+   VmaAllocationCreateInfo and go to point 1.

+-# If failed, return `VK_ERROR_OUT_OF_DEVICE_MEMORY`.

+

+\section general_considerations_features_not_supported Features not supported

+

+Features deliberately excluded from the scope of this library:

+

+-# **Data transfer.** Uploading (streaming) and downloading data of buffers and images

+   between CPU and GPU memory and related synchronization is responsibility of the user.

+   Defining some "texture" object that would automatically stream its data from a

+   staging copy in CPU memory to GPU memory would rather be a feature of another,

+   higher-level library implemented on top of VMA.

+   VMA doesn't record any commands to a `VkCommandBuffer`. It just allocates memory.

+-# **Recreation of buffers and images.** Although the library has functions for

+   buffer and image creation: vmaCreateBuffer(), vmaCreateImage(), you need to

+   recreate these objects yourself after defragmentation. That is because the big

+   structures `VkBufferCreateInfo`, `VkImageCreateInfo` are not stored in

+   #VmaAllocation object.

+-# **Handling CPU memory allocation failures.** When dynamically creating small C++

+   objects in CPU memory (not Vulkan memory), allocation failures are not checked

+   and handled gracefully, because that would complicate code significantly and

+   is usually not needed in desktop PC applications anyway.

+   Success of an allocation is just checked with an assert.

+-# **Code free of any compiler warnings.** Maintaining the library to compile and

+   work correctly on so many different platforms is hard enough. Being free of

+   any warnings, on any version of any compiler, is simply not feasible.

+   There are many preprocessor macros that make some variables unused, function parameters unreferenced,

+   or conditional expressions constant in some configurations.

+   The code of this library should not be bigger or more complicated just to silence these warnings.

+   It is recommended to disable such warnings instead.

+-# This is a C++ library with C interface. **Bindings or ports to any other programming languages** are welcome as external projects but

+   are not going to be included into this repository.
