Description

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

Additionally, ATTACHMENT_LOAD_OP_NONE_EXT is introduced to avoid unnecessary synchronization when an attachment is not used during a render pass at all. In combination with ATTACHMENT_STORE_OP_NONE_EXT, this is useful as an alternative to preserve attachments in applications that cannot decide if an attachment will be used in a render pass until after the necessary pipelines have been created.

Promotion to `VK_KHR_load_store_op_none`

All functionality in this extension is included in VK_KHR_load_store_op_none, with the suffix changed to KHR. The original enum names are still available as aliases of the KHR functionality.

New Enum Constants

EXT_LOAD_STORE_OP_NONE_EXTENSION_NAME

EXT_LOAD_STORE_OP_NONE_SPEC_VERSION
Extending AttachmentLoadOp:
- ATTACHMENT_LOAD_OP_NONE_EXT
Extending AttachmentStoreOp:
- ATTACHMENT_STORE_OP_NONE_EXT

While ATTACHMENT_STORE_OP_NONE is part of Vulkan 1.3, this extension was not promoted to core either in whole or in part. This functionality was promoted from VK_KHR_dynamic_rendering.
