+\page staying_within_budget Staying within budget
+
+When developing a graphics-intensive game or program, it is important to avoid allocating
+more GPU memory than it's physically available. When the memory is over-committed,
+various bad things can happen, depending on the specific GPU, graphics driver, and
+operating system:
+
+- It may just work without any problems.
+- The application may slow down because some memory blocks are moved to system RAM
+ and the GPU has to access them through PCI Express bus.
+- A new allocation may take very long time to complete, even few seconds, and possibly
+ freeze entire system.
+- The new allocation may fail with `VK_ERROR_OUT_OF_DEVICE_MEMORY`.
+- It may even result in GPU crash (TDR), observed as `VK_ERROR_DEVICE_LOST`
+ returned somewhere later.
+
+\section staying_within_budget_querying_for_budget Querying for budget
+
+To query for current memory usage and available budget, use function vmaGetBudget().
+Returned structure #VmaBudget contains quantities expressed in bytes, per Vulkan memory heap.
+
+Please note that this function returns different information and works faster than
+vmaCalculateStats(). vmaGetBudget() can be called every frame or even before every
+allocation, while vmaCalculateStats() is intended to be used rarely,
+only to obtain statistical information, e.g. for debugging purposes.
+
+It is recommended to use VK_EXT_memory_budget device extension to obtain information
+about the budget from Vulkan device. VMA is able to use this extension automatically.
+When not enabled, the allocator behaves same way, but then it estimates current usage
+and available budget based on its internal information and Vulkan memory heap sizes,
+which may be less precise. In order to use this extension:
+
+1. Make sure extensions VK_EXT_memory_budget and VK_KHR_get_physical_device_properties2
+ required by it are available and enable them. Please note that the first is a device
+ extension and the second is instance extension!
+2. Use flag #VMA_ALLOCATOR_CREATE_EXT_MEMORY_BUDGET_BIT when creating #VmaAllocator object.
+3. Make sure to call vmaSetCurrentFrameIndex() every frame. Budget is queried from
+ Vulkan inside of it to avoid overhead of querying it with every allocation.
+
+\section staying_within_budget_controlling_memory_usage Controlling memory usage
+
+There are many ways in which you can try to stay within the budget.
+
+First, when making new allocation requires allocating a new memory block, the library
+tries not to exceed the budget automatically. If a block with default recommended size
+(e.g. 256 MB) would go over budget, a smaller block is allocated, possibly even
+dedicated memory for just this resource.
+
+If the size of the requested resource plus current memory usage is more than the
+budget, by default the library still tries to create it, leaving it to the Vulkan
+implementation whether the allocation succeeds or fails. You can change this behavior
+by using #VMA_ALLOCATION_CREATE_WITHIN_BUDGET_BIT flag. With it, the allocation is
+not made if it would exceed the budget or if the budget is already exceeded.
+Some other allocations become lost instead to make room for it, if the mechanism of
+[lost allocations](@ref lost_allocations) is used.
+If that is not possible, the allocation fails with `VK_ERROR_OUT_OF_DEVICE_MEMORY`.
+Example usage pattern may be to pass the #VMA_ALLOCATION_CREATE_WITHIN_BUDGET_BIT flag
+when creating resources that are not essential for the application (e.g. the texture
+of a specific object) and not to pass it when creating critically important resources
+(e.g. render targets).
+
+Finally, you can also use #VMA_ALLOCATION_CREATE_NEVER_ALLOCATE_BIT flag to make sure
+a new allocation is created only when it fits inside one of the existing memory blocks.
+If it would require to allocate a new block, if fails instead with `VK_ERROR_OUT_OF_DEVICE_MEMORY`.
+This also ensures that the function call is very fast because it never goes to Vulkan
+to obtain a new block.
+
+Please note that creating \ref custom_memory_pools with VmaPoolCreateInfo::minBlockCount
+set to more than 0 will try to allocate memory blocks without checking whether they
+fit within budget.

+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`.
+Fill in `VkPhysicalDeviceFeatures2` structure instead and pass it as `VkDeviceCreateInfo::pNext`.
+Enable this device feature - attach additional structure `VkPhysicalDeviceCoherentMemoryFeaturesAMD` to
+`VkPhysicalDeviceFeatures2::pNext` and set its member `deviceCoherentMemory` to `VK_TRUE`.
+
+5) While creating #VmaAllocator with vmaCreateAllocator() inform VMA that you
+have enabled this extension and feature - add #VMA_ALLOCATOR_CREATE_AMD_DEVICE_COHERENT_MEMORY_BIT
+to VmaAllocatorCreateInfo::flags.
+
+\section vk_amd_device_coherent_memory_usage Usage
+
+After following steps described above, you can create VMA allocations and custom pools
+out of the special `DEVICE_COHERENT` and `DEVICE_UNCACHED` memory types on eligible
+devices. There are multiple ways to do it, for example:
+
+- You can request or prefer to allocate out of such memory types by adding
+ `VK_MEMORY_PROPERTY_DEVICE_COHERENT_BIT_AMD` to VmaAllocationCreateInfo::requiredFlags
+ or VmaAllocationCreateInfo::preferredFlags. Those flags can be freely mixed with
+ other ways of \ref choosing_memory_type, like setting VmaAllocationCreateInfo::usage.
+- If you manually found memory type index to use for this purpose, force allocation
+ from this specific index by setting VmaAllocationCreateInfo::memoryTypeBits `= 1u << index`.
+
