Description

This extension allows users to request robustness on a per-pipeline stage basis.

As robustBufferAccess and other robustness features may have an adverse effect on performance, this extension is designed to allow users to request robust behavior only where it may be needed.

New Structures

• Extending VkGraphicsPipelineCreateInfo, VkComputePipelineCreateInfo, VkPipelineShaderStageCreateInfo, VkRayTracingPipelineCreateInfoKHR:
  • VkPipelineRobustnessCreateInfoEXT
• Extending VkPhysicalDeviceFeatures2, VkDeviceCreateInfo:
  • VkPhysicalDevicePipelineRobustnessFeaturesEXT
• Extending VkPhysicalDeviceProperties2:
  • VkPhysicalDevicePipelineRobustnessPropertiesEXT

New Enums

• VkPipelineRobustnessBufferBehaviorEXT
• VkPipelineRobustnessImageBehaviorEXT

Promotion to Vulkan 1.4

Functionality in this extension is included in core Vulkan 1.4 with the EXT suffix omitted. The original type, enum and command names are still available as aliases of the core functionality.
