VkDedicatedAllocationImageCreateInfoNV(3)

# VkDedicatedAllocationImageCreateInfoNV(3) Manual Page

## Name

VkDedicatedAllocationImageCreateInfoNV - Specify that an image is bound to a dedicated memory resource

## 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:

    // Provided by VK_NV_dedicated_allocation
    typedef struct VkDedicatedAllocationImageCreateInfoNV {
        VkStructureType    sType;
        const void*        pNext;
        VkBool32           dedicatedAllocation;
    } VkDedicatedAllocationImageCreateInfoNV;

## Members

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this 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

- VUID-VkDedicatedAllocationImageCreateInfoNV-dedicatedAllocation-00994
  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)

- VUID-VkDedicatedAllocationImageCreateInfoNV-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_DEDICATED_ALLOCATION_IMAGE_CREATE_INFO_NV
