C Specification

The VkCommandBufferInheritanceRenderingInfo structure is defined as:

// Provided by VK_VERSION_1_3
typedef struct VkCommandBufferInheritanceRenderingInfo {
    VkStructureType          sType;
    const void*              pNext;
    VkRenderingFlags         flags;
    uint32_t                 viewMask;
    uint32_t                 colorAttachmentCount;
    const VkFormat*          pColorAttachmentFormats;
    VkFormat                 depthAttachmentFormat;
    VkFormat                 stencilAttachmentFormat;
    VkSampleCountFlagBits    rasterizationSamples;
} VkCommandBufferInheritanceRenderingInfo;

or the equivalent

// Provided by VK_KHR_dynamic_rendering
typedef VkCommandBufferInheritanceRenderingInfo VkCommandBufferInheritanceRenderingInfoKHR;

Members

  • sType is a VkStructureType value identifying this structure.

  • pNext is NULL or a pointer to a structure extending this structure

  • flags is a bitmask of VkRenderingFlagBits used by the render pass instance.

  • viewMask is the view mask used for rendering.

  • colorAttachmentCount is the number of color attachments specified in the render pass instance.

  • pColorAttachmentFormats is a pointer to an array of VkFormat values defining the format of color attachments.

  • depthAttachmentFormat is a VkFormat value defining the format of the depth attachment.

  • stencilAttachmentFormat is a VkFormat value defining the format of the stencil attachment.

  • rasterizationSamples is a VkSampleCountFlagBits specifying the number of samples used in rasterization.

Description

If the pNext chain of VkCommandBufferInheritanceInfo includes a VkCommandBufferInheritanceRenderingInfo structure, then that structure controls parameters of dynamic render pass instances that the VkCommandBuffer can be executed within. If VkCommandBufferInheritanceInfo::renderPass is not VK_NULL_HANDLE, or VK_COMMAND_BUFFER_USAGE_RENDER_PASS_CONTINUE_BIT is not specified in VkCommandBufferBeginInfo::flags, parameters of this structure are ignored.

If colorAttachmentCount is 0 and the variableMultisampleRate feature is enabled, rasterizationSamples is ignored.

If depthAttachmentFormat, stencilAttachmentFormat, or any element of pColorAttachmentFormats is VK_FORMAT_UNDEFINED, it indicates that the corresponding attachment is unused within the render pass and writes to those attachments are discarded.

Valid Usage

  • VUID-VkCommandBufferInheritanceRenderingInfo-colorAttachmentCount-06004
    If colorAttachmentCount is not 0, rasterizationSamples must be a valid VkSampleCountFlagBits value

  • VUID-VkCommandBufferInheritanceRenderingInfo-variableMultisampleRate-06005
    If the variableMultisampleRate feature is not enabled, rasterizationSamples must be a valid VkSampleCountFlagBits value

  • VUID-VkCommandBufferInheritanceRenderingInfo-depthAttachmentFormat-06540
    If depthAttachmentFormat is not VK_FORMAT_UNDEFINED, it must be a format that includes a depth component

  • VUID-VkCommandBufferInheritanceRenderingInfo-depthAttachmentFormat-06007
    If depthAttachmentFormat is not VK_FORMAT_UNDEFINED, it must be a format with potential format features that include VK_FORMAT_FEATURE_DEPTH_STENCIL_ATTACHMENT_BIT

  • VUID-VkCommandBufferInheritanceRenderingInfo-pColorAttachmentFormats-06492
    If any element of pColorAttachmentFormats is not VK_FORMAT_UNDEFINED, it must be a format with potential format features that include VK_FORMAT_FEATURE_COLOR_ATTACHMENT_BIT , or VK_FORMAT_FEATURE_2_LINEAR_COLOR_ATTACHMENT_BIT_NV if the linearColorAttachment feature is enabled

  • VUID-VkCommandBufferInheritanceRenderingInfo-stencilAttachmentFormat-06541
    If stencilAttachmentFormat is not VK_FORMAT_UNDEFINED, it must be a format that includes a stencil aspect

  • VUID-VkCommandBufferInheritanceRenderingInfo-stencilAttachmentFormat-06199
    If stencilAttachmentFormat is not VK_FORMAT_UNDEFINED, it must be a format with potential format features that include VK_FORMAT_FEATURE_DEPTH_STENCIL_ATTACHMENT_BIT

  • VUID-VkCommandBufferInheritanceRenderingInfo-depthAttachmentFormat-06200
    If depthAttachmentFormat is not VK_FORMAT_UNDEFINED and stencilAttachmentFormat is not VK_FORMAT_UNDEFINED, depthAttachmentFormat must equal stencilAttachmentFormat

  • VUID-VkCommandBufferInheritanceRenderingInfo-multiview-06008
    If the multiview feature is not enabled, viewMask must be 0

  • VUID-VkCommandBufferInheritanceRenderingInfo-viewMask-06009
    The index of the most significant bit in viewMask must be less than maxMultiviewViewCount

Valid Usage (Implicit)

  • VUID-VkCommandBufferInheritanceRenderingInfo-sType-sType
    sType must be VK_STRUCTURE_TYPE_COMMAND_BUFFER_INHERITANCE_RENDERING_INFO

  • VUID-VkCommandBufferInheritanceRenderingInfo-flags-parameter
    flags must be a valid combination of VkRenderingFlagBits values

  • VUID-VkCommandBufferInheritanceRenderingInfo-pColorAttachmentFormats-parameter
    If colorAttachmentCount is not 0, pColorAttachmentFormats must be a valid pointer to an array of colorAttachmentCount valid VkFormat values

  • VUID-VkCommandBufferInheritanceRenderingInfo-depthAttachmentFormat-parameter
    depthAttachmentFormat must be a valid VkFormat value

  • VUID-VkCommandBufferInheritanceRenderingInfo-stencilAttachmentFormat-parameter
    stencilAttachmentFormat must be a valid VkFormat value

  • VUID-VkCommandBufferInheritanceRenderingInfo-rasterizationSamples-parameter
    If rasterizationSamples is not 0, rasterizationSamples must be a valid VkSampleCountFlagBits value
