## 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 the type of 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 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)

• 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
