+\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.).
+
+![Resource aliasing (overlap)](../gfx/Aliasing.png)
+
+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.

+\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.

+VK_AMD_device_coherent_memory is a device extension that enables access to
+additional memory types with `VK_MEMORY_PROPERTY_DEVICE_COHERENT_BIT_AMD` and
+`VK_MEMORY_PROPERTY_DEVICE_UNCACHED_BIT_AMD` flag. It is useful mostly for
+allocation of buffers intended for writing "breadcrumb markers" in between passes
+or draw calls, which in turn are useful for debugging GPU crash/hang/TDR cases.
+
+When the extension is available but has not been enabled, Vulkan physical device
+still exposes those memory types, but their usage is forbidden. VMA automatically
+takes care of that - it returns `VK_ERROR_FEATURE_NOT_PRESENT` when an attempt
+to allocate memory of such type is made.
+
+If you want to use this extension in connection with VMA, follow these steps:
+
+\section vk_amd_device_coherent_memory_initialization Initialization
+
+1) Call `vkEnumerateDeviceExtensionProperties` for the physical device.
+Check if the extension is supported - if returned array of `VkExtensionProperties` contains "VK_AMD_device_coherent_memory".
+
+2) Call `vkGetPhysicalDeviceFeatures2` for the physical device instead of old `vkGetPhysicalDeviceFeatures`.
+Attach additional structure `VkPhysicalDeviceCoherentMemoryFeaturesAMD` to `VkPhysicalDeviceFeatures2::pNext` to be returned.
+Check if the device feature is really supported - check if `VkPhysicalDeviceCoherentMemoryFeaturesAMD::deviceCoherentMemory` is true.
+
+3) While creating device with `vkCreateDevice`, enable this extension - add "VK_AMD_device_coherent_memory"
+to the list passed as `VkDeviceCreateInfo::ppEnabledExtensionNames`.
+
+4) While creating the device, also don't set `VkDeviceCreateInfo::pEnabledFeatures`.

+Enable this device feature - attach additional structure `VkPhysicalDeviceCoherentMemoryFeaturesAMD` to
