Description

Renderpasses, and specifically subpass self-dependencies enable much of the same functionality as the framebuffer fetch and pixel local storage extensions did for OpenGL ES. But certain techniques such as programmable blending are awkward or impractical to implement with these alone, in part because a self-dependency is required every time a fragment will read a value at a given sample coordinate.

This extension extends the mechanism of input attachments to allow access to framebuffer attachments when used as both input and color, or depth/stencil, attachments from one fragment to the next, in rasterization order, without explicit synchronization.

See renderpass feedback loops for more information.

• Extending PipelineDepthStencilStateCreateFlagBits:

  • PIPELINE_DEPTH_STENCIL_STATE_CREATE_RASTERIZATION_ORDER_ATTACHMENT_DEPTH_ACCESS_BIT_ARM
  • PIPELINE_DEPTH_STENCIL_STATE_CREATE_RASTERIZATION_ORDER_ATTACHMENT_STENCIL_ACCESS_BIT_ARM

• Extending StructureType:

  • STRUCTURE_TYPE_PHYSICAL_DEVICE_RASTERIZATION_ORDER_ATTACHMENT_ACCESS_FEATURES_ARM

• Extending SubpassDescriptionFlagBits:

  • SUBPASS_DESCRIPTION_RASTERIZATION_ORDER_ATTACHMENT_DEPTH_ACCESS_BIT_ARM
  • SUBPASS_DESCRIPTION_RASTERIZATION_ORDER_ATTACHMENT_STENCIL_ACCESS_BIT_ARM

Issues

1) Is there any interaction with the VK_KHR_dynamic_rendering extension?

No. This extension only affects reads from input attachments. Render pass instances begun with cmdBeginRenderingKHR do not have input attachments and a different mechanism will be needed to provide similar functionality in this case.

Examples

None.

data PhysicalDeviceRasterizationOrderAttachmentAccessFeaturesEXT

VkPhysicalDeviceRasterizationOrderAttachmentAccessFeaturesEXT - Structure describing whether rasterization order attachment access can be supported by an implementation

Members

This structure describes the following features:

Description

If the PhysicalDeviceRasterizationOrderAttachmentAccessFeaturesEXT structure is included in the pNext chain of the PhysicalDeviceFeatures2 structure passed to getPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. PhysicalDeviceRasterizationOrderAttachmentAccessFeaturesEXT can also be used in the pNext chain of DeviceCreateInfo to selectively enable these features.
