C Specification

To determine the memory requirements for a plane of a disjoint image, add a VkImagePlaneMemoryRequirementsInfo structure to the pNext chain of the VkImageMemoryRequirementsInfo2 structure.

The VkImagePlaneMemoryRequirementsInfo structure is defined as:

// Provided by VK_VERSION_1_1
typedef struct VkImagePlaneMemoryRequirementsInfo {
    VkStructureType          sType;
    const void*              pNext;
    VkImageAspectFlagBits    planeAspect;
} VkImagePlaneMemoryRequirementsInfo;

or the equivalent

// Provided by VK_KHR_sampler_ycbcr_conversion
typedef VkImagePlaneMemoryRequirementsInfo VkImagePlaneMemoryRequirementsInfoKHR;

Members

  • sType is a VkStructureType value identifying this structure.

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

  • planeAspect is a VkImageAspectFlagBits value specifying the aspect corresponding to the image plane to query.

Description

Valid Usage

  • VUID-VkImagePlaneMemoryRequirementsInfo-planeAspect-02281
    If the image’s tiling is VK_IMAGE_TILING_LINEAR or VK_IMAGE_TILING_OPTIMAL, then planeAspect must be a single valid multi-planar aspect mask bit

  • VUID-VkImagePlaneMemoryRequirementsInfo-planeAspect-02282
    If the image’s tiling is VK_IMAGE_TILING_DRM_FORMAT_MODIFIER_EXT, then planeAspect must be a single valid memory plane for the image (that is, aspectMask must specify a plane index that is less than the VkDrmFormatModifierPropertiesEXT::drmFormatModifierPlaneCount associated with the image’s format and VkImageDrmFormatModifierPropertiesEXT::drmFormatModifier)

Valid Usage (Implicit)

  • VUID-VkImagePlaneMemoryRequirementsInfo-sType-sType
    sType must be VK_STRUCTURE_TYPE_IMAGE_PLANE_MEMORY_REQUIREMENTS_INFO

  • VUID-VkImagePlaneMemoryRequirementsInfo-planeAspect-parameter
    planeAspect must be a valid VkImageAspectFlagBits value
