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's 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: - -\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's 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_CPU_ONLY; -allocCreateInfo.flags = 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 - -There are some exceptions though, when you should consider mapping memory only for a short period of time: - -- When operating system is Windows 7 or 8.x (Windows 10 is not affected because it uses WDDM2), - device is discrete AMD GPU, - and memory type is the special 256 MiB pool of `DEVICE_LOCAL + HOST_VISIBLE` memory - (selected when you use #VMA_MEMORY_USAGE_CPU_TO_GPU), - then whenever a memory block allocated from this memory type stays mapped - for the time of any call to `vkQueueSubmit()` or `vkQueuePresentKHR()`, this - block is migrated by WDDM to system RAM, which degrades performance. It doesn't - matter if that particular memory block is actually used by the command buffer - being submitted. -- Keeping many large memory blocks mapped may impact performance or stability of some debugging tools. - -\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`.

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. -Some other allocations become lost instead to make room for it, if the mechanism of -[lost allocations](@ref lost_allocations) is used. -If that is not possible, the allocation 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). - -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. - -Please note that creating \ref custom_memory_pools with VmaPoolCreateInfo::minBlockCount -set to more than 0 will 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.). - - - -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.usage = VMA_MEMORY_USAGE_GPU_ONLY; - -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!

Vulkan Memory Allocator can help you with that by supporting a concept of -"lost allocations". - -To create an allocation that can become lost, include #VMA_ALLOCATION_CREATE_CAN_BECOME_LOST_BIT -flag in VmaAllocationCreateInfo::flags. Before using a buffer or image bound to -such allocation in every new frame, you need to query it if it's not lost. -To check it, call vmaTouchAllocation(). -If the allocation is lost, you should not use it or buffer/image bound to it. -You mustn't forget to destroy this allocation and this buffer/image. -vmaGetAllocationInfo() can also be used for checking status of the allocation. -Allocation is lost when returned VmaAllocationInfo::deviceMemory == `VK_NULL_HANDLE`. - -To create an allocation that can make some other allocations lost to make room -for it, use #VMA_ALLOCATION_CREATE_CAN_MAKE_OTHER_LOST_BIT flag. You will -usually use both flags #VMA_ALLOCATION_CREATE_CAN_MAKE_OTHER_LOST_BIT and -#VMA_ALLOCATION_CREATE_CAN_BECOME_LOST_BIT at the same time. - -Warning! Current implementation uses quite naive, brute force algorithm, -which can make allocation calls that use #VMA_ALLOCATION_CREATE_CAN_MAKE_OTHER_LOST_BIT -flag quite slow. A new, more optimal algorithm and data structure to speed this -up is planned for the future. - -<b>Q: When interleaving creation of new allocations with usage of existing ones, -how do you make sure that an allocation won't become lost while it's used in the -current frame?</b> - -It is ensured because vmaTouchAllocation() / vmaGetAllocationInfo() not only returns allocation -status/parameters and checks whether it's not lost, but when it's not, it also -atomically marks it as used in the current frame, which makes it impossible to -become lost in that frame. It uses lockless algorithm, so it works fast and -doesn't involve locking any internal mutex. - -<b>Q: What if my allocation may still be in use by the GPU when it's rendering a -previous frame while I already submit new frame on the CPU?</b> - -You can make sure that allocations "touched" by vmaTouchAllocation() / vmaGetAllocationInfo() will not -become lost for a number of additional frames back from the current one by -specifying this number as VmaAllocatorCreateInfo::frameInUseCount (for default -memory pool) and VmaPoolCreateInfo::frameInUseCount (for custom pool). - -<b>Q: How do you inform the library when new frame starts?</b> - -You need to call function vmaSetCurrentFrameIndex(). - -Example code: - -\code -struct MyBuffer -{ - VkBuffer m_Buf = nullptr; - VmaAllocation m_Alloc = nullptr; - - // Called when the buffer is really needed in the current frame. - void EnsureBuffer(); -}; - -void MyBuffer::EnsureBuffer() -{ - // Buffer has been created. - if(m_Buf != VK_NULL_HANDLE) - { - // Check if its allocation is not lost + mark it as used in current frame. - if(vmaTouchAllocation(allocator, m_Alloc)) - { - // It's all OK - safe to use m_Buf. - return; - } - } - - // Buffer not yet exists or lost - destroy and recreate it. - - vmaDestroyBuffer(allocator, m_Buf, m_Alloc); - - 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.usage = VMA_MEMORY_USAGE_GPU_ONLY; - allocCreateInfo.flags = VMA_ALLOCATION_CREATE_CAN_BECOME_LOST_BIT | - VMA_ALLOCATION_CREATE_CAN_MAKE_OTHER_LOST_BIT; - - vmaCreateBuffer(allocator, &bufCreateInfo, &allocCreateInfo, &m_Buf, &m_Alloc, nullptr); -} -\endcode - -When using lost allocations, you may see some Vulkan validation layer warnings -about overlapping regions of memory bound to different kinds of buffers and -images. This is still valid as long as you implement proper handling of lost -allocations (like in the example above) and don't use them. - -You can create an allocation that is already in lost state from the beginning using function -vmaCreateLostAllocation().

If you create a staging copy -of a resource to be written by CPU and then used as a source of transfer to -another resource placed in the GPU memory, that staging resource should be -created with #VMA_MEMORY_USAGE_CPU_ONLY. Please read the descriptions of these -enums carefully for details. - -<b>Unnecessary use of custom pools</b> - -\ref custom_memory_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, limit maximum amount of memory they can occupy, or make some of them -push out the other through the mechanism of \ref lost_allocations. 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 usage_patterns_simple Simple patterns - -\subsection usage_patterns_simple_render_targets Render targets - -<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> -Create them in video memory that is fastest to access from GPU using -#VMA_MEMORY_USAGE_GPU_ONLY. - -Consider using [VK_KHR_dedicated_allocation](@ref vk_khr_dedicated_allocation) extension -and/or manually 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 e.g. when -display resolution changes. -Prefer to create such resources first and all other GPU resources (like textures and vertex buffers) later. - -\subsection usage_patterns_simple_immutable_resources Immutable resources - -<b>When:</b> -Any resources that you fill on CPU only once (aka "immutable") or infrequently -and then read frequently on GPU, -e.g. textures, vertex and index buffers, constant buffers that don't change often. - -<b>What to do:</b> -Create them in video memory that is fastest to access from GPU using -#VMA_MEMORY_USAGE_GPU_ONLY. - -To initialize content of such resource, create a CPU-side (aka "staging") copy of it -in system memory - #VMA_MEMORY_USAGE_CPU_ONLY, map it, fill it, -and submit a transfer from it to the GPU resource. -You can keep the staging copy if you need it for another upload transfer in the future. -If you don't, you can destroy it or reuse this buffer for uploading different resource -after the transfer finishes. - -Prefer to create just buffers in system memory rather than images, even for uploading textures. -Use `vkCmdCopyBufferToImage()`. -Dont use images with `VK_IMAGE_TILING_LINEAR`. - -\subsection usage_patterns_dynamic_resources Dynamic resources - -<b>When:</b> -Any resources that change frequently (aka "dynamic"), e.g. every frame or every draw call, -written on CPU, read on GPU. - -<b>What to do:</b> -Create them using #VMA_MEMORY_USAGE_CPU_TO_GPU. -You can map it and write to it directly on CPU, as well as read from it on GPU. - -This is a more complex situation. Different solutions are possible, -and the best one depends on specific GPU type, but you can use this simple approach for the start. -Prefer to write to such resource sequentially (e.g. using `memcpy`). -Don't perform random access or any reads from it on CPU, as it may be very slow. -Also note that textures written directly from the host through a mapped pointer need to be in LINEAR not OPTIMAL layout. - -\subsection usage_patterns_readback Readback - -<b>When:</b> -Resources that contain data written by GPU that you want to read back on CPU, -e.g. results of some computations. - -<b>What to do:</b> -Create them using #VMA_MEMORY_USAGE_GPU_TO_CPU. -You can write to them directly on GPU, as well as map and read them on CPU. - -\section usage_patterns_advanced Advanced patterns - -\subsection usage_patterns_integrated_graphics Detecting integrated graphics - -You can support integrated graphics (like Intel HD Graphics, AMD APU) better -by detecting it in Vulkan. -To do it, call `vkGetPhysicalDeviceProperties()`, inspect -`VkPhysicalDeviceProperties::deviceType` and look for `VK_PHYSICAL_DEVICE_TYPE_INTEGRATED_GPU`. -When you find it, you can assume that memory is unified and all memory types are comparably fast -to access from GPU, regardless of `VK_MEMORY_PROPERTY_DEVICE_LOCAL_BIT`. - -You can then sum up sizes of all available memory heaps and treat them as useful for -your GPU resources, instead of only `DEVICE_LOCAL` ones. -You can also prefer to create your resources in memory types that are `HOST_VISIBLE` to map them -directly instead of submitting explicit transfer (see below). - -\subsection usage_patterns_direct_vs_transfer Direct access versus transfer - -For resources that you frequently write on CPU and read on GPU, many solutions are possible: - --# Create one copy in video memory using #VMA_MEMORY_USAGE_GPU_ONLY, - second copy in system memory using #VMA_MEMORY_USAGE_CPU_ONLY and submit explicit transfer each time. --# Create just a single copy using #VMA_MEMORY_USAGE_CPU_TO_GPU, map it and fill it on CPU, - read it directly on GPU. --# Create just a single copy using #VMA_MEMORY_USAGE_CPU_ONLY, map it and fill it on CPU, - read it directly on GPU. - -Which solution is the most efficient depends on your resource and especially on the GPU. -It is best to measure it and then make the decision. -Some general recommendations: - -- On integrated graphics use (2) or (3) to avoid unnecessary time and memory overhead - related to using a second copy and making transfer. -- For small resources (e.g. constant buffers) use (2). - Discrete AMD cards have special 256 MiB pool of video memory that is directly mappable. - Even if the resource ends up in system memory, its data may be cached on GPU after first - fetch over PCIe bus. -- For larger resources (e.g. textures), decide between (1) and (2). - You may want to differentiate NVIDIA and AMD, e.g. by looking for memory type that is - both `DEVICE_LOCAL` and `HOST_VISIBLE`. When you find it, use (2), otherwise use (1). - -Similarly, for resources that you frequently write on GPU and read on CPU, multiple -solutions are possible: - --# Create one copy in video memory using #VMA_MEMORY_USAGE_GPU_ONLY, - second copy in system memory using #VMA_MEMORY_USAGE_GPU_TO_CPU and submit explicit tranfer each time. --# Create just single copy using #VMA_MEMORY_USAGE_GPU_TO_CPU, write to it directly on GPU, - map it and read it on CPU. - -You should take some measurements to decide which option is faster in case of your specific -resource. - -Note that textures accessed directly from the host through a mapped pointer need to be in LINEAR layout, -which may slow down their usage on the device. -Textures accessed only by the device and transfer operations can use OPTIMAL layout. - -If you don't want to specialize your code for specific types of GPUs, you can still make -an simple optimization for cases when your resource ends up in mappable memory to use it -directly in this case instead of creating CPU-side staging copy. -For details see [Finding out if memory is mappable](@ref memory_mapping_finding_if_memory_mappable). - - -\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. -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.

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 happens when you use lost allocations, and a new image or buffer is - created in place of an existing object that became lost. - - It may happen also 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 and #VMA_ALLOCATION_CREATE_CAN_MAKE_OTHER_LOST_BIT flag was - specified, try to find space in existing blocks, possilby making some other - allocations lost. --# 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. -- Allocations for imported/exported external memory. They tend to require - explicit memory type index and dedicated allocation anyway, so they don't - interact with main features of this library. Such special purpose allocations - should be made manually, using `vkCreateBuffer()` and `vkAllocateMemory()`. -- Sub-allocation of parts of one large buffer. Although recommended as a good practice, - it is the user's responsibility to implement such logic on top of VMA. -- 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's 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.

This is the easiest and recommended way to use this library. + +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. +For more details, see description of this enum. + +For example, if you want to create a uniform buffer that will be filled using +transfer only once or infrequently and used for rendering every frame, you can +do it using following code: + +\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_GPU_ONLY; + +VkBuffer buffer; +VmaAllocation allocation; +vmaCreateBuffer(allocator, &bufferInfo, &allocInfo, &buffer, &allocation, nullptr); +\endcode + +\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_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. + +If you use VmaAllocationCreateInfo::usage, it is just internally converted to +a set of required and preferred flags. + +\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: + +\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_CPU_ONLY; +allocCreateInfo.flags = 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 + +There are some exceptions though, when you should consider mapping memory only for a short period of time: + +- When operating system is Windows 7 or 8.x (Windows 10 is not affected because it uses WDDM2), + device is discrete AMD GPU, + and memory type is the special 256 MiB pool of `DEVICE_LOCAL + HOST_VISIBLE` memory + (selected when you use #VMA_MEMORY_USAGE_CPU_TO_GPU), + then whenever a memory block allocated from this memory type stays mapped + for the time of any call to `vkQueueSubmit()` or `vkQueuePresentKHR()`, this + block is migrated by WDDM to system RAM, which degrades performance. It doesn't + matter if that particular memory block is actually used by the command buffer + being submitted. +- Keeping many large memory blocks mapped may impact performance or stability of some debugging tools. + +\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. + +Please note that memory allocated with #VMA_MEMORY_USAGE_CPU_ONLY is guaranteed to be `HOST_COHERENT`. + +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 this platform you may not need to bother. + +\section memory_mapping_finding_if_memory_mappable Finding out if memory is mappable + +It may happen that your allocation ends up in memory that is `HOST_VISIBLE` (available for mapping) +despite it wasn't explicitly requested. +For example, application may work on integrated graphics with unified memory (like Intel) or +allocation from video memory might have failed, so the library chose system memory as fallback. + +You can detect this case and map such allocation to access its memory on CPU directly, +instead of launching a transfer operation. +In order to do that: call vmaGetAllocationMemoryProperties() +and look for `VK_MEMORY_PROPERTY_HOST_VISIBLE_BIT` flag. + +\code +VkBufferCreateInfo bufCreateInfo = { VK_STRUCTURE_TYPE_BUFFER_CREATE_INFO }; +bufCreateInfo.size = sizeof(ConstantBuffer); +bufCreateInfo.usage = VK_BUFFER_USAGE_UNIFORM_BUFFER_BIT | VK_BUFFER_USAGE_TRANSFER_DST_BIT; + +VmaAllocationCreateInfo allocCreateInfo = {}; +allocCreateInfo.usage = VMA_MEMORY_USAGE_GPU_ONLY; +allocCreateInfo.preferredFlags = VK_MEMORY_PROPERTY_HOST_VISIBLE_BIT; + +VkBuffer buf; +VmaAllocation alloc; +vmaCreateBuffer(allocator, &bufCreateInfo, &allocCreateInfo, &buf, &alloc, nullptr); + +VkMemoryPropertyFlags memFlags; +vmaGetAllocationMemoryProperties(allocator, alloc, &memFlags); +if((memFlags & VK_MEMORY_PROPERTY_HOST_VISIBLE_BIT) != 0) +{ + // Allocation ended up in mappable memory.

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. +The allocation 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). + +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. + +Please note that creating \ref custom_memory_pools with VmaPoolCreateInfo::minBlockCount +set to more than 0 will 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.). + + + +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.usage = VMA_MEMORY_USAGE_GPU_ONLY; + +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 of 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. + +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 +// Create a pool that can have at most 2 blocks, 128 MiB each. +VmaPoolCreateInfo poolCreateInfo = {}; +poolCreateInfo.memoryTypeIndex = ... +poolCreateInfo.blockSize = 128ull * 1024 * 1024; +poolCreateInfo.maxBlockCount = 2; + +VmaPool pool; +vmaCreatePool(allocator, &poolCreateInfo, &pool); + +// 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; +VmaAllocationInfo allocInfo; +vmaCreateBuffer(allocator, &bufCreateInfo, &allocCreateInfo, &buf, &alloc, &allocInfo); +\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. + +\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; // Whatever. +exampleBufCreateInfo.usage = VK_BUFFER_USAGE_UNIFORM_BUFFER_BIT | VK_BUFFER_USAGE_TRANSFER_DST_BIT; // Change if needed. + +VmaAllocationCreateInfo allocCreateInfo = {}; +allocCreateInfo.usage = VMA_MEMORY_USAGE_GPU_ONLY; // Change if needed. + +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. + + + +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. + + + +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. + + + +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. + + + +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 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 is available only in pools with one memory block - +VmaPoolCreateInfo::maxBlockCount must be 1. Otherwise behavior is undefined. + +\section buddy_algorithm Buddy allocation algorithm + +There is another allocation algorithm that can be used with custom pools, called +"buddy". Its internal data structure is based on a binary tree of blocks, each having +size that is a power of two and a half of its parent's size. When you want to +allocate memory of certain size, a free node in the tree is located. If it is too +large, it is recursively split into two halves (called "buddies"). However, if +requested allocation size is not a power of two, the size of the allocation is +aligned up to the nearest power of two and the remaining space is wasted. When +two buddy nodes become free, they are merged back into one larger node. + + + +The advantage of buddy allocation algorithm over default algorithm is faster +allocation and deallocation, as well as smaller external fragmentation. The +disadvantage is more wasted space (internal fragmentation). +For more information, please search the Internet for "Buddy memory allocation" - +sources that describe this concept in general. + +To use buddy allocation algorithm with a custom pool, add flag +#VMA_POOL_CREATE_BUDDY_ALGORITHM_BIT to VmaPoolCreateInfo::flags while creating +#VmaPool object. + +Several limitations apply to pools that use buddy algorithm: + +- It is recommended to use VmaPoolCreateInfo::blockSize that is a power of two. + Otherwise, only largest power of two smaller than the size is used for + allocations. The remaining space always stays unused. +- [Margins](@ref debugging_memory_usage_margins) and + [corruption detection](@ref debugging_memory_usage_corruption_detection) + don't work in such pools. +- [Defragmentation](@ref defragmentation) doesn't work with allocations made from + such pool. + +\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: +structure #VmaDefragmentationInfo2, function vmaDefragmentationBegin(), vmaDefragmentationEnd(). +Given set of allocations, +this function can move them to compact used memory, ensure more continuous free +space and possibly also free some `VkDeviceMemory` blocks. + +What the defragmentation does is: + +- Updates #VmaAllocation objects to point to new `VkDeviceMemory` and offset. + After allocation has been moved, its VmaAllocationInfo::deviceMemory and/or + VmaAllocationInfo::offset changes. You must query them again using + vmaGetAllocationInfo() if you need them. +- Moves actual data in memory. + +What it doesn't do, so you need to do it yourself: + +- Recreate buffers and images that were bound to allocations that were defragmented and + bind them with their new places in memory. + You must use `vkDestroyBuffer()`, `vkDestroyImage()`, + `vkCreateBuffer()`, `vkCreateImage()`, vmaBindBufferMemory(), vmaBindImageMemory() + for that purpose and NOT vmaDestroyBuffer(), + vmaDestroyImage(), vmaCreateBuffer(), vmaCreateImage(), because you don't need to + destroy or create allocation objects! +- Recreate views and update descriptors that point to these buffers and images. + +\section defragmentation_cpu Defragmenting CPU memory + +Following example demonstrates how you can run defragmentation on CPU. +Only allocations created in memory types that are `HOST_VISIBLE` can be defragmented. +Others are ignored. + +The way it works is: + +- It temporarily maps entire memory blocks when necessary. +- It moves data using `memmove()` function. + +\code +// Given following variables already initialized: +VkDevice device; +VmaAllocator allocator; +std::vector<VkBuffer> buffers; +std::vector<VmaAllocation> allocations; + + +const uint32_t allocCount = (uint32_t)allocations.size(); +std::vector<VkBool32> allocationsChanged(allocCount); + +VmaDefragmentationInfo2 defragInfo = {}; +defragInfo.allocationCount = allocCount; +defragInfo.pAllocations = allocations.data(); +defragInfo.pAllocationsChanged = allocationsChanged.data(); +defragInfo.maxCpuBytesToMove = VK_WHOLE_SIZE; // No limit. +defragInfo.maxCpuAllocationsToMove = UINT32_MAX; // No limit. + +VmaDefragmentationContext defragCtx; +vmaDefragmentationBegin(allocator, &defragInfo, nullptr, &defragCtx); +vmaDefragmentationEnd(allocator, defragCtx); + +for(uint32_t i = 0; i < allocCount; ++i) +{ + if(allocationsChanged[i]) + { + // Destroy buffer that is immutably bound to memory region which is no longer valid. + vkDestroyBuffer(device, buffers[i], nullptr); + + // Create new buffer with same parameters. + VkBufferCreateInfo bufferInfo = ...; + vkCreateBuffer(device, &bufferInfo, nullptr, &buffers[i]); + + // You can make dummy call to vkGetBufferMemoryRequirements here to silence validation layer warning. + + // Bind new buffer to new memory region.

Some fragmentation may still remain - this is normal. + +\section defragmentation_custom_algorithm Writing custom defragmentation algorithm + +If you want to implement your own, custom defragmentation algorithm, +there is infrastructure prepared for that, +but it is not exposed through the library API - you need to hack its source code. +Here are steps needed to do this: + +-# Main thing you need to do is to define your own class derived from base abstract + class `VmaDefragmentationAlgorithm` and implement your version of its pure virtual methods. + See definition and comments of this class for details. +-# Your code needs to interact with device memory block metadata. + If you need more access to its data than it is provided by its public interface, + declare your new class as a friend class e.g. in class `VmaBlockMetadata_Generic`. +-# If you want to create a flag that would enable your algorithm or pass some additional + flags to configure it, add them to `VmaDefragmentationFlagBits` and use them in + VmaDefragmentationInfo2::flags. +-# Modify function `VmaBlockVectorDefragmentationContext::Begin` to create object + of your new class whenever needed. + + +\page statistics Statistics + +This library contains functions that return information about its internal state, +especially the amount of memory allocated from Vulkan. +Please keep in mind that these functions need to traverse all internal data structures +to gather these information, so they may be quite time-consuming. +Don't call them too often. + +\section statistics_numeric_statistics Numeric statistics + +You can query for overall statistics of the allocator using function vmaCalculateStats(). +Information are returned using structure #VmaStats. +It contains #VmaStatInfo - number of allocated blocks, number of allocations +(occupied ranges in these blocks), number of unused (free) ranges in these blocks, +number of bytes used and unused (but still allocated from Vulkan) and other information. +They are summed across memory heaps, memory types and total for whole allocator. + +You can query for statistics of a custom pool using function vmaGetPoolStats(). +Information are returned using structure #VmaPoolStats. + +You can query for information about 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 vmaCalculateStats(). +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 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 are also not active in custom pools created with #VMA_POOL_CREATE_BUDDY_ALGORITHM_BIT flag. + +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 +

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. +- **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. +*/ |
