vkCmdSetAttachmentFeedbackLoopEnableEXT - Specify whether attachment feedback loops are enabled dynamically on a command buffer

Description

For attachments that are written to in a render pass, only attachments with the aspects specified in aspectMask can be accessed as non-attachments by subsequent drawing commands.

Valid Usage

• The attachmentFeedbackLoopDynamicState feature must be enabled

• aspectMask must only include IMAGE_ASPECT_NONE, IMAGE_ASPECT_COLOR_BIT, IMAGE_ASPECT_DEPTH_BIT, and IMAGE_ASPECT_STENCIL_BIT
• If the attachmentFeedbackLoopLayout feature is not enabled, aspectMask must be IMAGE_ASPECT_NONE

Valid Usage (Implicit)

• commandBuffer must be a valid CommandBuffer handle

• aspectMask must be a valid combination of ImageAspectFlagBits values
• commandBuffer must be in the recording state
• The CommandPool that commandBuffer was allocated from must support graphics operations
• This command must only be called outside of a video coding scope

VkPhysicalDeviceAttachmentFeedbackLoopDynamicStateFeaturesEXT - Structure describing if dynamic feedback loops can be used

Members

This structure describes the following features:

Description

If the PhysicalDeviceAttachmentFeedbackLoopDynamicStateFeaturesEXT 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. PhysicalDeviceAttachmentFeedbackLoopDynamicStateFeaturesEXT can also be used in the pNext chain of DeviceCreateInfo to selectively enable these features.
