Vulkan.Extensions.VK_EXT_attachment_feedback_loop_dynamic_state

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 QUEUE_GRAPHICS_BIT operations

• This command must only be called outside of a video coding scope

Host Synchronization

• Host access to commandBuffer must be externally synchronized

• Host access to the CommandPool that commandBuffer was allocated from must be externally synchronized

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. If the application wishes to use a Device with any features described by PhysicalDeviceAttachmentFeedbackLoopDynamicStateFeaturesEXT, it must add an instance of the structure, with the desired feature members set to TRUE, to the pNext chain of DeviceCreateInfo when creating the Device.
