<li>If you want to allocate a region of device memory without association with any specific image or buffer, you can use function <a class="el" href="group__group__alloc.html#gabf28077dbf82d0908b8acbe8ee8dd9b8" title="General purpose memory allocation.">vmaAllocateMemory()</a>.

<li><b>This is the easiest and recommended way to use this library:</b> If you want to create a buffer or an image, allocate memory for it and bind them together, all in one call, you can use function <a class="el" href="group__group__alloc.html#gac72ee55598617e8eecca384e746bab51" title="Creates a new VkBuffer, allocates and binds memory for it.">vmaCreateBuffer()</a>, <a class="el" href="group__group__alloc.html#ga02a94f25679275851a53e82eacbcfc73" title="Function similar to vmaCreateBuffer().">vmaCreateImage()</a>.</li>
</ol>
<p >When using 3. or 4., the library internally queries Vulkan for memory types supported for that buffer or image (function <code>vkGetBufferMemoryRequirements()</code>) and uses only one of these types.</p>
<p >If no memory type can be found that meets all the requirements, these functions return <code>VK_ERROR_FEATURE_NOT_PRESENT</code>.</p>
<p >You can leave <a class="el" href="struct_vma_allocation_create_info.html" title="Parameters of new VmaAllocation.">VmaAllocationCreateInfo</a> structure completely filled with zeros. It means no requirements are specified for memory type. It is valid, although not very useful.</p>

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.

Linear allocation algorithm</h1>

Free-at-once</h2>
<p >In a pool that uses linear algorithm, you still need to free all the allocations individually, e.g. by using <a class="el" href="group__group__alloc.html#ga5fea5518972ae9094b1526cbcb19b05f" title="Frees memory previously allocated using vmaAllocateMemory(), vmaAllocateMemoryForBuffer(),...">vmaFreeMemory()</a> or <a class="el" href="group__group__alloc.html#ga0d9f4e4ba5bf9aab1f1c746387753d77" title="Destroys Vulkan buffer and frees allocated memory.">vmaDestroyBuffer()</a>.

Attach additional structure <code>VkPhysicalDeviceBufferDeviceAddressFeatures*</code> to <code>VkPhysicalDeviceFeatures2::pNext</code> to be returned. Check if the device feature is really supported - check if <code>VkPhysicalDeviceBufferDeviceAddressFeatures::bufferDeviceAddress</code> is true.</p>
<p>3) (For Vulkan version &lt; 1.2) While creating device with <code>vkCreateDevice</code>, enable this extension - add "VK_KHR_buffer_device_address" to the list passed as <code>VkDeviceCreateInfo::ppEnabledExtensionNames</code>.</p>
<p>4) While creating the device, also don't set <code>VkDeviceCreateInfo::pEnabledFeatures</code>. Fill in <code>VkPhysicalDeviceFeatures2</code> structure instead and pass it as <code>VkDeviceCreateInfo::pNext</code>. Enable this device feature - attach additional structure <code>VkPhysicalDeviceBufferDeviceAddressFeatures*</code> to <code>VkPhysicalDeviceFeatures2::pNext</code> and set its member <code>bufferDeviceAddress</code> to <code>VK_TRUE</code>.</p>

Usage</h1>
<p >After following steps described above, you can create buffers with <code>VK_BUFFER_USAGE_SHADER_DEVICE_ADDRESS_BIT*</code> using VMA. The library automatically adds <code>VK_MEMORY_ALLOCATE_DEVICE_ADDRESS_BIT*</code> to allocated memory blocks wherever it might be needed.</p>
<p >Please note that the library supports only <code>VK_BUFFER_USAGE_SHADER_DEVICE_ADDRESS_BIT*</code>. The second part of this functionality related to "capture and replay" is not supported, as it is intended for usage in debugging tools like RenderDoc, not in everyday Vulkan usage.</p>

Cache flush and invalidate</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 <b>invalidate</b> cache before reading of mapped pointer and <b>flush</b> cache after writing to mapped pointer.

<p>If you want to create a buffer with a specific minimum alignment out of default pools, use special function <a class="el" href="group__group__alloc.html#gaa06a690013a0d01e60894ac378083834" title="Creates a buffer with additional minimum alignment.">vmaCreateBufferWithAlignment()</a>, which takes additional parameter <code>minAlignment</code>.</p>
<p>Note the problem of alignment affects only resources placed inside bigger <code>VkDeviceMemory</code> 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. </p>

Selecting Vulkan version</h2>
<p >VMA supports Vulkan version down to 1.0, for backward compatibility. If you want to use higher version, you need to inform the library about it. This is a two-step process.</p>
<p ><b>Step 1: Compile time.</b> By default, VMA compiles with code supporting the highest Vulkan version found in the included <code>&lt;vulkan/vulkan.h&gt;</code> that is also supported by the library. If this is OK, you don't need to do anything. However, if you want to compile VMA as if only some lower Vulkan version was available, define macro <code>VMA_VULKAN_VERSION</code> before every <code>#include "vk_mem_alloc.h"</code>. It should have decimal numeric value in form of ABBBCCC, where A = major, BBB = minor, CCC = patch Vulkan version. For example, to compile against Vulkan 1.2:</p>

You need to issue a memory barrier to make sure commands that use <code>img1</code> and <code>img2</code> 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 <code>img1</code> and then want to use <code>img2</code>, you need to issue an image memory barrier for <code>img2</code> with <code>oldLayout</code> = <code>VK_IMAGE_LAYOUT_UNDEFINED</code>.</p>
<p>Additional considerations:</p>
<ul>
<li>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 <code>VK_IMAGE_CREATE_ALIAS_BIT</code> flag.</li>
<li>You can create more complex layout where different images and buffers are bound at different offsets inside one large allocation. For example, one can imagine a big texture used in some render passes, aliasing with a set of many small buffers used between in some further passes. To bind a resource at non-zero offset in an allocation, use <a class="el" href="group__group__alloc.html#ga927c944f45e0f2941182abb6f608e64a" title="Binds buffer to allocation with additional parameters.">vmaBindBufferMemory2()</a> / <a class="el" href="group__group__alloc.html#gaa8251ee81b0045a443e35b8e8aa021bc" title="Binds image to allocation with additional parameters.">vmaBindImageMemory2()</a>.</li>

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="group__group__alloc.html#ga86dd08aba8633bfa4ad0df2e76481d8b" title="Returns current information about specified allocation.">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().">VmaAllocationInfo</a>. </p>

Additional considerations</h1>
<p >The "virtual allocator" functionality is implemented on a level of individual memory blocks. Keeping track of a whole collection of blocks, allocating new ones when out of free space, deleting empty ones, and deciding which one to try first for a new allocation must be implemented by the user.</p>
<p >Alternative allocation algorithms are supported, just like in custom pools of the real GPU memory. See enum <a class="el" href="group__group__virtual.html#ga88bcf8c1cd3bb1610ff7343811c65bca" title="Flags to be passed as VmaVirtualBlockCreateInfo::flags.">VmaVirtualBlockCreateFlagBits</a> to learn how to specify them (e.g. <a class="el" href="group__group__virtual.html#gga88bcf8c1cd3bb1610ff7343811c65bcaae6423e2fa2f3c9211b21c819e3f10f96" title="Enables alternative, linear allocation algorithm in this virtual block.">VMA_VIRTUAL_BLOCK_CREATE_LINEAR_ALGORITHM_BIT</a>).

<p>After following steps described above, you can create VMA allocations and custom pools out of the special <code>DEVICE_COHERENT</code> and <code>DEVICE_UNCACHED</code> memory types on eligible devices. There are multiple ways to do it, for example:</p>
<ul>
<li>You can request or prefer to allocate out of such memory types by adding <code>VK_MEMORY_PROPERTY_DEVICE_UNCACHED_BIT_AMD</code> to <a class="el" href="struct_vma_allocation_create_info.html#a9166390303ff42d783305bc31c2b6b90" title="Flags that must be set in a Memory Type chosen for an allocation.">VmaAllocationCreateInfo::requiredFlags</a> or <a class="el" href="struct_vma_allocation_create_info.html#a7fe8d81a1ad10b2a2faacacee5b15d6d" title="Flags that preferably should be set in a memory type chosen for an allocation.">VmaAllocationCreateInfo::preferredFlags</a>.
