<div class="textblock"><p>VK_KHR_dedicated_allocation is a Vulkan extension which can be used to improve performance on some GPUs. It augments Vulkan API with possibility to query driver whether it prefers particular buffer or image to have its own, dedicated allocation (separate <code>VkDeviceMemory</code> block) for better efficiency - to be able to do some internal optimizations.</p>
<p>The extension is supported by this library. It will be used automatically when enabled. To enable it:</p>
<p>1 . When creating Vulkan device, check if following 2 device extensions are supported (call <code>vkEnumerateDeviceExtensionProperties()</code>). If yes, enable them (fill <code>VkDeviceCreateInfo::ppEnabledExtensionNames</code>).</p>
<ul>
<li>VK_KHR_get_memory_requirements2</li>
<li>VK_KHR_dedicated_allocation</li>
</ul>
<p>If you enabled these extensions:</p>
<p>2 . Query device for pointers to following 2 extension functions, using <code>vkGetDeviceProcAddr()</code>. Pass them in structure <a class="el" href="struct_vma_vulkan_functions.html" title="Pointers to some Vulkan functions - a subset used by the library. ">VmaVulkanFunctions</a> while creating your <code>VmaAllocator</code>.</p>
<ul>
<li><code>vkGetBufferMemoryRequirements2KHR</code></li>
<li><code>vkGetImageMemoryRequirements2KHR</code></li>
</ul>
<p>Other members of this structure can be null as long as you leave <code>VMA_STATIC_VULKAN_FUNCTIONS</code> defined to 1, which is the default.</p>

<p>When using the extension together with Vulkan Validation Layer, you will receive warnings like this: </p><pre class="fragment">vkBindBufferMemory(): Binding memory to buffer 0x33 but vkGetBufferMemoryRequirements() has not been called on that buffer.
</pre><p>It is OK, you should just ignore it. It happens because you use function <code>vkGetBufferMemoryRequirements2KHR()</code> instead of standard <code>vkGetBufferMemoryRequirements()</code>, while the validation layer seems to be unaware of it.</p>
