Description

This extension adds a new image layout, IMAGE_LAYOUT_ATTACHMENT_FEEDBACK_LOOP_OPTIMAL_EXT, which allows applications to have an image layout in which they are able to both render to and sample/fetch from the same subresource of an image in a given render pass.

New Structures

• Extending PhysicalDeviceFeatures2, DeviceCreateInfo:

  • PhysicalDeviceAttachmentFeedbackLoopLayoutFeaturesEXT

New Enum Constants

• EXT_ATTACHMENT_FEEDBACK_LOOP_LAYOUT_EXTENSION_NAME

• EXT_ATTACHMENT_FEEDBACK_LOOP_LAYOUT_SPEC_VERSION

• Extending DependencyFlagBits:

  • DEPENDENCY_FEEDBACK_LOOP_BIT_EXT

• Extending ImageLayout:

  • IMAGE_LAYOUT_ATTACHMENT_FEEDBACK_LOOP_OPTIMAL_EXT

• Extending ImageUsageFlagBits:

  • IMAGE_USAGE_ATTACHMENT_FEEDBACK_LOOP_BIT_EXT

• Extending PipelineCreateFlagBits:

  • PIPELINE_CREATE_COLOR_ATTACHMENT_FEEDBACK_LOOP_BIT_EXT
  • PIPELINE_CREATE_DEPTH_STENCIL_ATTACHMENT_FEEDBACK_LOOP_BIT_EXT

• Extending StructureType:

  • STRUCTURE_TYPE_PHYSICAL_DEVICE_ATTACHMENT_FEEDBACK_LOOP_LAYOUT_FEATURES_EXT

Version History

• Revision 2, 2022-04-04 (Joshua Ashton)

  • Renamed from VALVE to EXT.
