C Specification
The VkPhysicalDeviceExtendedSparseAddressSpacePropertiesNV structure
is defined as:
// Provided by VK_NV_extended_sparse_address_space
typedef struct VkPhysicalDeviceExtendedSparseAddressSpacePropertiesNV {
VkStructureType sType;
void* pNext;
VkDeviceSize extendedSparseAddressSpaceSize;
VkImageUsageFlags extendedSparseImageUsageFlags;
VkBufferUsageFlags extendedSparseBufferUsageFlags;
} VkPhysicalDeviceExtendedSparseAddressSpacePropertiesNV;
Members
-
sTypeis a VkStructureType value identifying this structure. -
pNextisNULLor a pointer to a structure extending this structure. -
extendedSparseAddressSpaceSizeis the total amount of address space available, in bytes, for sparse memory resources of all usages if theextendedSparseAddressSpacefeature is enabled. This must be greater than or equal toVkPhysicalDeviceLimits::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. -
extendedSparseImageUsageFlagsis a bitmask of VkImageUsageFlagBits of usages which may allow an implementation to use the fullextendedSparseAddressSpaceSizespace. -
extendedSparseBufferUsageFlagsis a bitmask of VkBufferUsageFlagBits of usages which may allow an implementation to use the fullextendedSparseAddressSpaceSizespace.
Description
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.
