<div class="textblock"><p>If your game oversubscribes video memory, if may work OK in previous-generation graphics APIs (DirectX 9, 10, 11, OpenGL) because resources are automatically paged to system RAM. In Vulkan you can't do it because when you run out of memory, an allocation just fails. If you have more data (e.g. textures) that can fit into VRAM and you don't need it all at once, you may want to upload them to GPU on demand and "push out" ones that are not used for a long time to make room for the new ones, effectively using VRAM (or a cartain memory pool) as a form of cache. Vulkan Memory Allocator can help you with that by supporting a concept of "lost allocations".</p>
-<p>To create an allocation that can become lost, include <code>VMA_ALLOCATION_CREATE_CAN_BECOME_LOST_BIT</code> flag in <a class="el" href="struct_vma_allocation_create_info.html#add09658ac14fe290ace25470ddd6d41b" title="Use VmaAllocationCreateFlagBits enum.

">VmaAllocationInfo::deviceMemory</a> is not <code>VK_NULL_HANDLE</code>. 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.</p>
-<p>To create an allocation that can make some other allocations lost to make room for it, use <code>VMA_ALLOCATION_CREATE_CAN_MAKE_OTHER_LOST_BIT</code> flag. You will usually use both flags <code>VMA_ALLOCATION_CREATE_CAN_MAKE_OTHER_LOST_BIT</code> and <code>VMA_ALLOCATION_CREATE_CAN_BECOME_LOST_BIT</code> at the same time.</p>
-<p>Warning! Current implementation uses quite naive, brute force algorithm, which can make allocation calls that use <code>VMA_ALLOCATION_CREATE_CAN_MAKE_OTHER_LOST_BIT</code> flag quite slow. A new, more optimal algorithm and data structure to speed this up is planned for the future.</p>

<div class="textblock"><p>To "map memory" in Vulkan means to obtain a CPU pointer to <code>VkDeviceMemory</code>, 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 <code>VK_MEMORY_PROPERTY_HOST_VISIBLE_BIT</code> flag. Functions <code>vkMapMemory()</code>, <code>vkUnmapMemory()</code> 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 <code>VkDeviceMemory</code> 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:</p>

Cache control</h1>
<p>Memory in Vulkan doesn't need to be unmapped before using it on GPU, but unless a memory types has <code>VK_MEMORY_PROPERTY_HOST_COHERENT_BIT</code> flag set, you need to manually invalidate cache before reading of mapped pointer using function <code>vkvkInvalidateMappedMemoryRanges()</code> and flush cache after writing to mapped pointer using function <code>vkFlushMappedMemoryRanges()</code>.

<p>Also, Windows drivers from all 3 PC GPU vendors (AMD, Intel, NVIDIA) currently provide <code>VK_MEMORY_PROPERTY_HOST_COHERENT_BIT</code> flag on all memory types that are <code>VK_MEMORY_PROPERTY_HOST_VISIBLE_BIT</code>, so on this platform you may not need to bother.</p>
<h1><a class="anchor" id="memory_mapping_finding_if_memory_mappable"></a>
Finding out if memory is mappable</h1>
<p>It may happen that your allocation ends up in memory that is <code>HOST_VISIBLE</code> (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.</p>
<p>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: inspect <code>allocInfo.memoryType</code>, call <a class="el" href="vk__mem__alloc_8h.html#a8701444752eb5de4464adb5a2b514bca" title="Given Memory Type Index, returns Property Flags of this memory type. ">vmaGetMemoryTypeProperties()</a>, and look for <code>VK_MEMORY_PROPERTY_HOST_VISIBLE_BIT</code> flag in properties of that memory type.</p>
-<p>You can even use <code>VMA_ALLOCATION_CREATE_MAPPED_BIT</code> flag while creating allocations that are not necessarily <code>HOST_VISIBLE</code> (e.g. using <code>VMA_MEMORY_USAGE_GPU_ONLY</code>). If the allocation ends up in memory type that is <code>HOST_VISIBLE</code>, it will be persistently mapped and you can use it directly. If not, the flag is just ignored. Example:</p>

Project setup</h1>
-<p>In your project code:</p>
+<p>Vulkan Memory Allocator comes in form of a 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.</p>
+<p>"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.</p>
+<p>To do it properly:</p>
<ol type="1">
-<li>Include "vk_mem_alloc.h" file wherever you want to use the library.</li>
-<li>In exacly one C++ file define following macro before include to build library implementation.</li>
+<li>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.</li>
+<li>In exacly one CPP file define following macro before this include. It enables also internal definitions.</li>

">vmaBuildStatsString()</a>. The result is guaranteed to be correct JSON. It uses ANSI encoding. Any strings provided by user (see <a class="el" href="allocation_annotation.html#allocation_names">Allocation names</a>) 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 <a class="el" href="vk__mem__alloc_8h.html#a3104eb30d8122c84dd8541063f145288">vmaFreeStatsString()</a>.</p>
+<p>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.</p>
+<p>The JSON string contains all the data that can be obtained using <a class="el" href="vk__mem__alloc_8h.html#a333b61c1788cb23559177531e6a93ca3" title="Retrieves statistics from current state of the Allocator. ">vmaCalculateStats()</a>. 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. </p>

+<p>Although the library provides convenience functions that create Vulkan buffer or image, allocate memory for it and bind them together, binding of the allocation to a buffer or an image is out of scope of the allocation itself. Allocation object can exist without buffer/image bound, binding can be done manually by the user, and destruction of it can be done independently of destruction of the allocation.</p>
+<p>The object also remembers its size and some other information. To retrieve this information, use function <a class="el" href="vk__mem__alloc_8h.html#a86dd08aba8633bfa4ad0df2e76481d8b" title="Returns current information about specified allocation and atomically marks it as used in current fra...">vmaGetAllocationInfo()</a> and inspect returned structure <a class="el" href="struct_vma_allocation_info.html" title="Parameters of VmaAllocation objects, that can be retrieved using function vmaGetAllocationInfo().

+Simple patterns</h1>
+<h2><a class="anchor" id="usage_patterns_simple_render_targets"></a>
+Render targets</h2>
+<p><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)").</p>
+<p><b>What to do:</b> Create them in video memory that is fastest to access from GPU using <a class="el" href="vk__mem__alloc_8h.html#aa5846affa1e9da3800e3e78fae2305ccac6b5dc1432d88647aa4cd456246eadf7">VMA_MEMORY_USAGE_GPU_ONLY</a>.</p>
+<p>Consider using <a class="el" href="vk_khr_dedicated_allocation.html">VK_KHR_dedicated_allocation</a> extension and/or manually creating them as dedicated allocations using <a class="el" href="vk__mem__alloc_8h.html#ad9889c10c798b040d59c92f257cae597a3fc311d855c2ff53f1090ef5c722b38f" title="Set this flag if the allocation should have its own memory block. ">VMA_ALLOCATION_CREATE_DEDICATED_MEMORY_BIT</a>, 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.</p>
+<h2><a class="anchor" id="usage_patterns_simple_immutable_resources"></a>
+Immutable resources</h2>
+<p><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.</p>
+<p><b>What to do:</b> Create them in video memory that is fastest to access from GPU using <a class="el" href="vk__mem__alloc_8h.html#aa5846affa1e9da3800e3e78fae2305ccac6b5dc1432d88647aa4cd456246eadf7">VMA_MEMORY_USAGE_GPU_ONLY</a>.</p>
+<p>To initialize content of such resource, create a CPU-side (aka "staging") copy of it in system memory - <a class="el" href="vk__mem__alloc_8h.html#aa5846affa1e9da3800e3e78fae2305cca40bdf4cddeffeb12f43d45ca1286e0a5">VMA_MEMORY_USAGE_CPU_ONLY</a>, 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.</p>
+<p>Prefer to create just buffers in system memory rather than images, even for uploading textures. Use <code>vkCmdCopyBufferToImage()</code>. Dont use images with <code>VK_IMAGE_TILING_LINEAR</code>.</p>
+<h2><a class="anchor" id="usage_patterns_dynamic_resources"></a>
+Dynamic resources</h2>
+<p><b>When:</b> Any resources that change frequently (aka "dynamic"), e.g. every frame or every draw call, written on CPU, read on GPU.</p>
+<p><b>What to do:</b> Create them using <a class="el" href="vk__mem__alloc_8h.html#aa5846affa1e9da3800e3e78fae2305cca9066b52c5a7079bb74a69aaf8b92ff67">VMA_MEMORY_USAGE_CPU_TO_GPU</a>. You can map it and write to it directly on CPU, as well as read from it on GPU.</p>
+<p>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 <code>memcpy</code>). Don't perform random access or any reads from it, as it may be very slow.</p>
+<h2><a class="anchor" id="usage_patterns_readback"></a>
+Readback</h2>
+<p><b>When:</b> Resources that contain data written by GPU that you want to read back on CPU, e.g. results of some computations.</p>
+<p><b>What to do:</b> Create them using <a class="el" href="vk__mem__alloc_8h.html#aa5846affa1e9da3800e3e78fae2305cca7b586d2fdaf82a463b58f581ed72be27">VMA_MEMORY_USAGE_GPU_TO_CPU</a>. You can write to them directly on GPU, as well as map and read them on CPU.</p>
+<h1><a class="anchor" id="usage_patterns_advanced"></a>
+Advanced patterns</h1>
+<h2><a class="anchor" id="usage_patterns_integrated_graphics"></a>
+Detecting integrated graphics</h2>
+<p>You can support integrated graphics (like Intel HD Graphics, AMD APU) better by detecting it in Vulkan. To do it, call <code>vkGetPhysicalDeviceProperties()</code>, inspect <code>VkPhysicalDeviceProperties::deviceType</code> and look for <code>VK_PHYSICAL_DEVICE_TYPE_INTEGRATED_GPU</code>. When you find it, you can assume that memory is unified and all memory types are equally fast to access from GPU, regardless of <code>VK_MEMORY_PROPERTY_DEVICE_LOCAL_BIT</code>.</p>
+<p>You can then sum up sizes of all available memory heaps and treat them as useful for your GPU resources, instead of only <code>DEVICE_LOCAL</code> ones. You can also prefer to create your resources in memory types that are <code>HOST_VISIBLE</code> to map them directly instead of submitting explicit transfer (see below).</p>
+<h2><a class="anchor" id="usage_patterns_direct_vs_transfer"></a>
+Direct access versus transfer</h2>
+<p>For resources that you frequently write on CPU and read on GPU, many solutions are possible:</p>
+<ol type="1">
+<li>Create one copy in video memory using <a class="el" href="vk__mem__alloc_8h.html#aa5846affa1e9da3800e3e78fae2305ccac6b5dc1432d88647aa4cd456246eadf7">VMA_MEMORY_USAGE_GPU_ONLY</a>, second copy in system memory using <a class="el" href="vk__mem__alloc_8h.html#aa5846affa1e9da3800e3e78fae2305cca40bdf4cddeffeb12f43d45ca1286e0a5">VMA_MEMORY_USAGE_CPU_ONLY</a> and submit explicit tranfer each time.</li>
+<li>Create just single copy using <a class="el" href="vk__mem__alloc_8h.html#aa5846affa1e9da3800e3e78fae2305cca9066b52c5a7079bb74a69aaf8b92ff67">VMA_MEMORY_USAGE_CPU_TO_GPU</a>, map it and fill it on CPU, read it directly on GPU.</li>
+<li>Create just single copy using <a class="el" href="vk__mem__alloc_8h.html#aa5846affa1e9da3800e3e78fae2305cca40bdf4cddeffeb12f43d45ca1286e0a5">VMA_MEMORY_USAGE_CPU_ONLY</a>, map it and fill it on CPU, read it directly on GPU.</li>
+</ol>
+<p>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:</p>
+<ul>
+<li>On integrated graphics use (2) or (3) to avoid unnecesary time and memory overhead related to using a second copy.</li>
+<li>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.</li>
+<li>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 <code>DEVICE_LOCAL</code> and <code>HOST_VISIBLE</code>. When you find it, use (2), otherwise use (1).</li>
+</ul>
+<p>Similarly, for resources that you frequently write on GPU and read on CPU, multiple solutions are possible:</p>
+<ol type="1">
+<li>Create one copy in video memory using <a class="el" href="vk__mem__alloc_8h.html#aa5846affa1e9da3800e3e78fae2305ccac6b5dc1432d88647aa4cd456246eadf7">VMA_MEMORY_USAGE_GPU_ONLY</a>, second copy in system memory using <a class="el" href="vk__mem__alloc_8h.html#aa5846affa1e9da3800e3e78fae2305cca7b586d2fdaf82a463b58f581ed72be27">VMA_MEMORY_USAGE_GPU_TO_CPU</a> and submit explicit tranfer each time.</li>
+<li>Create just single copy using <a class="el" href="vk__mem__alloc_8h.html#aa5846affa1e9da3800e3e78fae2305cca7b586d2fdaf82a463b58f581ed72be27">VMA_MEMORY_USAGE_GPU_TO_CPU</a>, write to it directly on GPU, map it and read it on CPU.</li>
+</ol>
+<p>You should take some measurements to decide which option is faster in case of your specific resource.</p>
+<p>If you don't want to specialize your code for specific types of GPUs, yon 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 <a class="el" href="memory_mapping.html#memory_mapping_finding_if_memory_mappable">Finding out if memory is mappable</a>. </p>

<p>Warning: This function is not 100% correct according to Vulkan specification. Use it at your own risk. That's because Vulkan doesn't guarantee that memory requirements (size and alignment) for a new buffer or image are consistent. They may be different even for subsequent calls with the same parameters. It really does happen on some platforms, especially with images.</p>
<p>Warning: This function may be time-consuming, so you shouldn't call it too often (like every frame or after every resource creation/destruction). You can call it on special occasions (like when reloading a game level or when you just destroyed a lot of objects). </p>

+\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.

+
+<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, as it may be very slow.
+

+Resources that contain data written by GPU that you want to read back on 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 equally 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 tranfer each time.
+-# Create just single copy using #VMA_MEMORY_USAGE_CPU_TO_GPU, map it and fill it on CPU,
+ read it directly on GPU.
+-# Create just 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 unnecesary time and memory overhead
+ related to using a second copy.
+- 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.
+
+If you don't want to specialize your code for specific types of GPUs, yon 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).
