| === Description |
| |
| This extension incorporates ename:VK_ATTACHMENT_STORE_OP_NONE_EXT from |
| `apiext:VK_QCOM_render_pass_store_ops`, enabling applications to avoid |
| unnecessary synchronization when an attachment is not written during a |
| render pass. |
| |
| Additionally, ename: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 ename: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. |
