C Specification

The VkRenderPassCreateInfo structure is defined as:

typedef struct VkRenderPassCreateInfo {
    VkStructureType                   sType;
    const void*                       pNext;
    VkRenderPassCreateFlags           flags;
    uint32_t                          attachmentCount;
    const VkAttachmentDescription*    pAttachments;
    uint32_t                          subpassCount;
    const VkSubpassDescription*       pSubpasses;
    uint32_t                          dependencyCount;
    const VkSubpassDependency*        pDependencies;
} VkRenderPassCreateInfo;

Members

  • sType is the type of this structure.

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

  • flags is reserved for future use.

  • attachmentCount is the number of attachments used by this render pass.

  • pAttachments points to an array of attachmentCount VkAttachmentDescription structures describing the attachments used by the render pass.

  • subpassCount is the number of subpasses to create.

  • pSubpasses points to an array of subpassCount VkSubpassDescription structures describing each subpass.

  • dependencyCount is the number of memory dependencies between pairs of subpasses.

  • pDependencies points to an array of dependencyCount VkSubpassDependency structures describing dependencies between pairs of subpasses.

Description

Note

Care should be taken to avoid a data race here; if any subpasses access attachments with overlapping memory locations, and one of those accesses is a write, a subpass dependency needs to be included between them.

Valid Usage
  • If the attachment member of any element of pInputAttachments, pColorAttachments, pResolveAttachments or pDepthStencilAttachment, or any element of pPreserveAttachments in any element of pSubpasses is not VK_ATTACHMENT_UNUSED, it must be less than attachmentCount

  • For any member of pAttachments with a loadOp equal to VK_ATTACHMENT_LOAD_OP_CLEAR, the first use of that attachment must not specify a layout equal to VK_IMAGE_LAYOUT_SHADER_READ_ONLY_OPTIMAL or VK_IMAGE_LAYOUT_DEPTH_STENCIL_READ_ONLY_OPTIMAL.

  • For any member of pAttachments with a stencilLoadOp equal to VK_ATTACHMENT_LOAD_OP_CLEAR, the first use of that attachment must not specify a layout equal to VK_IMAGE_LAYOUT_SHADER_READ_ONLY_OPTIMAL or VK_IMAGE_LAYOUT_DEPTH_STENCIL_READ_ONLY_OPTIMAL.

  • For any member of pAttachments with a loadOp equal to VK_ATTACHMENT_LOAD_OP_CLEAR, the first use of that attachment must not specify a layout equal to VK_IMAGE_LAYOUT_DEPTH_READ_ONLY_STENCIL_ATTACHMENT_OPTIMAL.

  • For any member of pAttachments with a stencilLoadOp equal to VK_ATTACHMENT_LOAD_OP_CLEAR, the first use of that attachment must not specify a layout equal to VK_IMAGE_LAYOUT_DEPTH_ATTACHMENT_STENCIL_READ_ONLY_OPTIMAL.

  • If the pNext chain includes an instance of VkRenderPassInputAttachmentAspectCreateInfo, the subpass member of each element of its pAspectReferences member must be less than subpassCount

  • If the pNext chain includes an instance of VkRenderPassInputAttachmentAspectCreateInfo, the inputAttachmentIndex member of each element of its pAspectReferences member must be less than the value of inputAttachmentCount in the member of pSubpasses identified by its subpass member

  • If the pNext chain includes an instance of VkRenderPassInputAttachmentAspectCreateInfo, for any element of the pInputAttachments member of any element of pSubpasses where the attachment member is not VK_ATTACHMENT_UNUSED, the aspectMask member of the corresponding element of VkRenderPassInputAttachmentAspectCreateInfo::pAspectReferences must only include aspects that are present in images of the format specified by the element of pAttachments at attachment

  • If the pNext chain includes an instance of VkRenderPassMultiviewCreateInfo, and its subpassCount member is not zero, that member must be equal to the value of subpassCount

  • If the pNext chain includes an instance of VkRenderPassMultiviewCreateInfo, if its dependencyCount member is not zero, it must be equal to dependencyCount

  • If the pNext chain includes an instance of VkRenderPassMultiviewCreateInfo, for each non-zero element of pViewOffsets, the srcSubpass and dstSubpass members of pDependencies at the same index must not be equal

  • If the pNext chain includes an instance of VkRenderPassMultiviewCreateInfo, for any element of pDependencies with a dependencyFlags member that does not include VK_DEPENDENCY_VIEW_LOCAL_BIT, the corresponding element of the pViewOffsets member of that VkRenderPassMultiviewCreateInfo instance must be 0

  • If the pNext chain includes an instance of VkRenderPassMultiviewCreateInfo, elements of its pViewMasks member must either all be 0, or all not be 0

  • If the pNext chain includes an instance of VkRenderPassMultiviewCreateInfo, and each element of its pViewMasks member is 0, the dependencyFlags member of each element of pDependencies must not include VK_DEPENDENCY_VIEW_LOCAL_BIT

  • If the pNext chain includes an instance of VkRenderPassMultiviewCreateInfo, and each element of its pViewMasks member is 0, correlatedViewMaskCount must be 0

  • If the pNext chain includes an instance of VkRenderPassMultiviewCreateInfo, each element of its pViewMask member must not have a bit set at an index greater than or equal to VkPhysicalDeviceLimits::maxFramebufferLayers

  • For any element of pDependencies, if the srcSubpass is not VK_SUBPASS_EXTERNAL, all stage flags included in the srcStageMask member of that dependency must be a pipeline stage supported by the pipeline identified by the pipelineBindPoint member of the source subpass

  • For any element of pDependencies, if the dstSubpass is not VK_SUBPASS_EXTERNAL, all stage flags included in the dstStageMask member of that dependency must be a pipeline stage supported by the pipeline identified by the pipelineBindPoint member of the destination subpass

  • The srcSubpass member of each element of pDependencies must be less than subpassCount

  • The dstSubpass member of each element of pDependencies must be less than subpassCount

Valid Usage (Implicit)
  • sType must be VK_STRUCTURE_TYPE_RENDER_PASS_CREATE_INFO

  • Each pNext member of any structure (including this one) in the pNext chain must be either NULL or a pointer to a valid instance of VkRenderPassFragmentDensityMapCreateInfoEXT, VkRenderPassInputAttachmentAspectCreateInfo, or VkRenderPassMultiviewCreateInfo

  • Each sType member in the pNext chain must be unique

  • If attachmentCount is not 0, pAttachments must be a valid pointer to an array of attachmentCount valid VkAttachmentDescription structures

  • pSubpasses must be a valid pointer to an array of subpassCount valid VkSubpassDescription structures

  • If dependencyCount is not 0, pDependencies must be a valid pointer to an array of dependencyCount valid VkSubpassDependency structures

  • subpassCount must be greater than 0
