VkPhysicalDeviceExtendedSparseAddressSpacePropertiesNV

The VkPhysicalDeviceExtendedSparseAddressSpacePropertiesNV structure is defined as:

typedef struct VkPhysicalDeviceExtendedSparseAddressSpacePropertiesNV {
    VkStructureType sType;
    void* pNext;
    VkDeviceSize extendedSparseAddressSpaceSize;
    VkImageUsageFlags extendedSparseImageUsageFlags;
    VkBufferUsageFlags extendedSparseBufferUsageFlags;
} VkPhysicalDeviceExtendedSparseAddressSpacePropertiesNV;

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• extendedSparseAddressSpaceSize is the total amount of address space available, in bytes, for sparse memory resources of all usages if the extendedSparseAddressSpace feature is enabled. This must be greater than or equal to VkPhysicalDeviceLimits::sparseAddressSpaceSize, and the difference in space must only be used with usages allowed below. This is an upper bound on the sum of the sizes of all sparse resources, regardless of whether any memory is bound to them.
• extendedSparseImageUsageFlags is a bitmask of VkImageUsageFlagBits of usages which may allow an implementation to use the full extendedSparseAddressSpaceSize space.
• extendedSparseBufferUsageFlags is a bitmask of VkBufferUsageFlagBits of usages which may allow an implementation to use the full extendedSparseAddressSpaceSize space.

If the VkPhysicalDeviceExtendedSparseAddressSpacePropertiesNV structure is included in the pNext chain of the VkPhysicalDeviceProperties2 structure passed to vkGetPhysicalDeviceProperties2, it is filled in with each corresponding implementation-dependent property.
