Description

This extension significantly simplifies synchronization in Vulkan by removing the need for image layout transitions in most cases. In particular, it guarantees that using the VK_IMAGE_LAYOUT_GENERAL layout everywhere possible is just as efficient as using the other layouts.

New Structures

• Extending VkPhysicalDeviceFeatures2, VkDeviceCreateInfo:
  • VkPhysicalDeviceUnifiedImageLayoutsFeaturesKHR

If VK_EXT_attachment_feedback_loop_layout and Vulkan Version 1.3 or VK_KHR_dynamic_rendering is supported:

• Extending VkRenderingAttachmentInfo:
  • VkAttachmentFeedbackLoopInfoEXT

New Enum Constants

• VK_KHR_UNIFIED_IMAGE_LAYOUTS_EXTENSION_NAME
• VK_KHR_UNIFIED_IMAGE_LAYOUTS_SPEC_VERSION
• Extending VkStructureType:
  • VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_UNIFIED_IMAGE_LAYOUTS_FEATURES_KHR

If VK_EXT_attachment_feedback_loop_layout and Vulkan Version 1.3 or VK_KHR_dynamic_rendering is supported:

• Extending VkStructureType:
  • VK_STRUCTURE_TYPE_ATTACHMENT_FEEDBACK_LOOP_INFO_EXT
