C Specification

The VkInputAttachmentAspectReference structure specifies an aspect mask for a specific input attachment of a specific subpass in the render pass.

subpass and inputAttachmentIndex index into the render pass as:

pCreateInfo->pSubpasses[subpass].pInputAttachments[inputAttachmentIndex]

// Provided by VK_VERSION_1_1
typedef struct VkInputAttachmentAspectReference {
    uint32_t              subpass;
    uint32_t              inputAttachmentIndex;
    VkImageAspectFlags    aspectMask;
} VkInputAttachmentAspectReference;

or the equivalent

// Provided by VK_KHR_maintenance2
typedef VkInputAttachmentAspectReference VkInputAttachmentAspectReferenceKHR;

Members

  • subpass is an index into the pSubpasses array of the parent VkRenderPassCreateInfo structure.

  • inputAttachmentIndex is an index into the pInputAttachments of the specified subpass.

  • aspectMask is a mask of which aspect(s) can be accessed within the specified subpass.

Description

Valid Usage

  • VUID-VkInputAttachmentAspectReference-aspectMask-02250
    aspectMask must not include VK_IMAGE_ASPECT_MEMORY_PLANE_i_BIT_EXT for any index i

Valid Usage (Implicit)
  • VUID-VkInputAttachmentAspectReference-aspectMask-parameter
    aspectMask must be a valid combination of VkImageAspectFlagBits values

  • VUID-VkInputAttachmentAspectReference-aspectMask-requiredbitmask
    aspectMask must not be 0
