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:

typedef struct VkImagePlaneMemoryRequirementsInfo {
    VkStructureType          sType;
    const void*              pNext;
    VkImageAspectFlagBits    planeAspect;
} VkImagePlaneMemoryRequirementsInfo;

or the equivalent

typedef VkImagePlaneMemoryRequirementsInfo VkImagePlaneMemoryRequirementsInfoKHR;


  • sType is the type of this structure.

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

  • planeAspect is the aspect corresponding to the image plane to query.


Valid Usage
  • If the image’s tiling is VK_IMAGE_TILING_LINEAR or VK_IMAGE_TILING_OPTIMAL, then planeAspect must be a single valid format plane for the image (that is, for a two-plane image planeAspect must be VK_IMAGE_ASPECT_PLANE_0_BIT or VK_IMAGE_ASPECT_PLANE_1_BIT, and for a three-plane image planeAspect must be VK_IMAGE_ASPECT_PLANE_0_BIT, VK_IMAGE_ASPECT_PLANE_1_BIT or VK_IMAGE_ASPECT_PLANE_2_BIT)

  • 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)

  • planeAspect must be a valid VkImageAspectFlagBits value
