VkRenderingAttachmentInfo

The VkRenderingAttachmentInfo structure is defined as:

typedef struct VkRenderingAttachmentInfo {
    VkStructureType sType;
    const void* pNext;
    VkImageView imageView;
    VkImageLayout imageLayout;
    VkResolveModeFlagBits resolveMode;
    VkImageView resolveImageView;
    VkImageLayout resolveImageLayout;
    VkAttachmentLoadOp loadOp;
    VkAttachmentStoreOp storeOp;
    VkClearValue clearValue;
} VkRenderingAttachmentInfo;

or the equivalent

typedef VkRenderingAttachmentInfo VkRenderingAttachmentInfoKHR;

sType is a VkStructureType value identifying this structure.
pNext is NULL or a pointer to a structure extending this structure.
imageView is the image view that will be used for rendering.
imageLayout is the layout that imageView will be in during rendering.
resolveMode is a VkResolveModeFlagBits value defining how data written to imageView will be resolved into resolveImageView.
resolveImageView is an image view used to write resolved data at the end of rendering.
resolveImageLayout is the layout that resolveImageView will be in during rendering.
loadOp is a VkAttachmentLoadOp value defining the load operation for the attachment.
storeOp is a VkAttachmentStoreOp value defining the store operation for the attachment.
clearValue is a VkClearValue structure defining values used to clear imageView when loadOp is VK_ATTACHMENT_LOAD_OP_CLEAR.

Values in imageView are loaded and stored according to the values of loadOp and storeOp, within the render area for each device specified in VkRenderingInfo. If imageView is VK_NULL_HANDLE, and resolveMode is not VK_RESOLVE_MODE_EXTERNAL_FORMAT_DOWNSAMPLE_ANDROID, other members of this structure are ignored; writes to this attachment will be discarded, and no load, store, or multisample resolve operations will be performed.

If resolveMode is VK_RESOLVE_MODE_NONE, then resolveImageView is ignored. If resolveMode is not VK_RESOLVE_MODE_NONE, and resolveImageView is not VK_NULL_HANDLE, a render pass multisample resolve operation is defined for the attachment subresource. If resolveMode is VK_RESOLVE_MODE_EXTERNAL_FORMAT_DOWNSAMPLE_ANDROID, and the nullColorAttachmentWithExternalFormatResolve limit is VK_TRUE, values are only undefined: once load operations have completed.

The resolve mode and store operation are independent; it is valid to write both resolved and unresolved values, and equally valid to discard the unresolved values while writing the resolved ones.

Store and resolve operations are only performed at the end of a render pass instance that does not specify the VK_RENDERING_SUSPENDING_BIT_KHR flag.

Load operations are only performed at the beginning of a render pass instance that does not specify the VK_RENDERING_RESUMING_BIT_KHR flag.

Image contents at the end of a suspended render pass instance remain defined for access by a resuming render pass instance.

If the nullColorAttachmentWithExternalFormatResolve limit is VK_TRUE, and resolveMode is VK_RESOLVE_MODE_EXTERNAL_FORMAT_DOWNSAMPLE_ANDROID, values in the color attachment will be loaded from the resolve attachment at the start of rendering, and may also be reloaded any time after a resolve occurs or the resolve attachment is written to; if this occurs it must happen-before any writes to the color attachment are performed which happen-after the resolve that triggers this. If any color component in the external format is subsampled, values will be read from the nearest sample in the image when they are loaded.
