C Specification

If the pNext chain includes a VkDedicatedAllocationImageCreateInfoNV structure, then that structure includes an enable controlling whether the image will have a dedicated memory allocation bound to it.

The VkDedicatedAllocationImageCreateInfoNV structure is defined as:

typedef struct VkDedicatedAllocationImageCreateInfoNV {
    VkStructureType    sType;
    const void*        pNext;
    VkBool32           dedicatedAllocation;
} VkDedicatedAllocationImageCreateInfoNV;

Members

  • sType is the type of this structure.

  • pNext is NULL or a pointer to an extension-specific structure.

  • dedicatedAllocation specifies whether the image will have a dedicated allocation bound to it.

Description

Note

Using a dedicated allocation for color and depth/stencil attachments or other large images may improve performance on some devices.

Valid Usage
  • If dedicatedAllocation is VK_TRUE, VkImageCreateInfo::flags must not include VK_IMAGE_CREATE_SPARSE_BINDING_BIT, VK_IMAGE_CREATE_SPARSE_RESIDENCY_BIT, or VK_IMAGE_CREATE_SPARSE_ALIASED_BIT

Valid Usage (Implicit)
  • sType must be VK_STRUCTURE_TYPE_DEDICATED_ALLOCATION_IMAGE_CREATE_INFO_NV
