<div class="contents">
<div class="textblock"><p>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, <code>min()</code> and <code>max()</code> functions, mutex, atomic etc. The library uses its own implementation of containers by default, but you can switch to using STL containers instead.</p>
<p>For example, define <code>VMA_ASSERT(expr)</code> before including the library to provide custom implementation of the assertion, compatible with your project. By default it is defined to standard C <code>assert(expr)</code> in <code>_DEBUG</code> configuration and empty otherwise.</p>
<h1><a class="anchor" id="config_Vulkan_functions"></a>
Pointers to Vulkan functions</h1>
<p>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 <a class="el" href="struct_vma_allocator.html" title="Represents main object of this library initialized.">VmaAllocator</a> doesn't work for you, you can try to reconfigure it.</p>
<p>First, the allocator tries to fetch pointers to Vulkan functions linked statically, like this:</p>
<div class="fragment"><div class="line">m_VulkanFunctions.vkAllocateMemory = (PFN_vkAllocateMemory)vkAllocateMemory;</div>
</div><!-- fragment --><p>If you want to disable this feature, set configuration macro: <code>#define VMA_STATIC_VULKAN_FUNCTIONS 0</code>.</p>
<p>Second, you can provide the pointers yourself by setting member <a class="el" href="struct_vma_allocator_create_info.html#a3dc197be3227da7338b1643f70db36bd" title="Pointers to Vulkan functions. Can be null.">VmaAllocatorCreateInfo::pVulkanFunctions</a>. You can fetch them e.g. using functions <code>vkGetInstanceProcAddr</code> and <code>vkGetDeviceProcAddr</code> or by using a helper library like <a href="https://github.com/zeux/volk">volk</a>.</p>
<p>Third, VMA tries to fetch remaining pointers that are still null by calling <code>vkGetInstanceProcAddr</code> and <code>vkGetDeviceProcAddr</code> on its own. If you want to disable this feature, set configuration macro: <code>#define VMA_DYNAMIC_VULKAN_FUNCTIONS 0</code>.</p>
<p>Finally, all the function pointers required by the library (considering selected Vulkan version and enabled extensions) are checked with <code>VMA_ASSERT</code> if they are not null.</p>
<h1><a class="anchor" id="custom_memory_allocator"></a>
Custom host memory allocator</h1>
<p>If you use custom allocator for CPU memory rather than default operator <code>new</code> and <code>delete</code> from C++, you can make this library using your allocator as well by filling optional member <a class="el" href="struct_vma_allocator_create_info.html#a6e409087e3be55400d0e4ccbe43c608d" title="Custom CPU memory allocation callbacks. Optional.">VmaAllocatorCreateInfo::pAllocationCallbacks</a>. These functions will be passed to Vulkan, as well as used by the library itself to make any CPU-side allocations.</p>

Initialization</h1>
<p>1) (For Vulkan version &lt; 1.2) Call <code>vkEnumerateDeviceExtensionProperties</code> for the physical device. Check if the extension is supported - if returned array of <code>VkExtensionProperties</code> contains "VK_EXT_buffer_device_address" or "VK_KHR_buffer_device_address".</p>
<p>1) (For Vulkan version &lt; 1.2) Call <code>vkEnumerateDeviceExtensionProperties</code> for the physical device. Check if the extension is supported - if returned array of <code>VkExtensionProperties</code> contains "VK_KHR_buffer_device_address".</p>
<p>2) Call <code>vkGetPhysicalDeviceFeatures2</code> for the physical device instead of old <code>vkGetPhysicalDeviceFeatures</code>. 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_EXT_buffer_device_address" or "VK_KHR_buffer_device_address" to the list passed as <code>VkDeviceCreateInfo::ppEnabledExtensionNames</code>.</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>

<h1><a class="anchor" id="enabling_buffer_device_address_usage"></a>
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_KHR</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>
<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>

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

\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.
