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.
