Description

This extension provides a new command to create render passes in a way that can be easily extended by other extensions through the substructures of render pass creation. The Vulkan 1.0 render pass creation sub-structures do not include sType/pNext members. Additionally, the render pass begin/next/end commands have been augmented with new extensible structures for passing additional subpass information.

The RenderPassMultiviewCreateInfo and InputAttachmentAspectReference structures that extended the original RenderPassCreateInfo are not accepted into the new creation functions, and instead their parameters are folded into this extension as follows:

• Elements of RenderPassMultiviewCreateInfo::pViewMasks are now specified in SubpassDescription2KHR::viewMask.

• Elements of RenderPassMultiviewCreateInfo::pViewOffsets are now specified in SubpassDependency2KHR::viewOffset.

• RenderPassMultiviewCreateInfo::correlationMaskCount and RenderPassMultiviewCreateInfo::pCorrelationMasks are directly specified in RenderPassCreateInfo2KHR.

• InputAttachmentAspectReference::aspectMask is now specified in the relevant input attachment reference in AttachmentReference2KHR::aspectMask

The details of these mappings are explained fully in the new structures.

Promotion to Vulkan 1.2

All functionality in this extension is included in core Vulkan 1.2, with the KHR suffix omitted. The original type, enum, and command names are still available as aliases of the core functionality.
