Description

This extension incorporates VK_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, VK_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 VK_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.
