Description

This extension allows applications to create single-pass render pass instances without needing to create render pass objects or framebuffers. Dynamic render passes can also span across multiple primary command buffers, rather than relying on secondary command buffers.

This extension also incorporates VK_ATTACHMENT_STORE_OP_NONE_KHR from VK_QCOM_render_pass_store_ops, enabling applications to avoid unnecessary synchronization when an attachment is not written during a render pass.

Promotion to Vulkan 1.3

Vulkan APIs in this extension are included in core Vulkan 1.3, with the KHR suffix omitted. External interactions defined by this extension, such as SPIR-V token names, retain their original names. The original Vulkan API names are still available as aliases of the core functionality.
