VkPhysicalDevicePipelineRobustnessFeatures

Structure describing whether an implementation supports robustness requests on a per-pipeline stage granularity

The VkPhysicalDevicePipelineRobustnessFeatures structure is defined as:

typedef struct VkPhysicalDevicePipelineRobustnessFeatures {
    VkStructureType sType;
    void* pNext;
    VkBool32 pipelineRobustness;
} VkPhysicalDevicePipelineRobustnessFeatures;

or the equivalent

typedef VkPhysicalDevicePipelineRobustnessFeatures VkPhysicalDevicePipelineRobustnessFeaturesEXT;

This structure describes the following feature:

  • sType is a VkStructureType value identifying this structure.
  • pNext is NULL or a pointer to a structure extending this structure.
  • pipelineRobustness indicates that robustness can be requested on a per-pipeline-stage granularity.

Enabling the pipelineRobustness feature may, on some platforms, incur a minor performance cost when the robustBufferAccess feature is not enabled, even for pipelines which do not make use of any robustness features. If robustness is not needed, the pipelineRobustness feature should not be enabled by an application.

If the VkPhysicalDevicePipelineRobustnessFeatures structure is included in the pNext chain of the VkPhysicalDeviceFeatures2 structure passed to vkGetPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. If the application wishes to use a VkDevice with any features described by VkPhysicalDevicePipelineRobustnessFeatures, it must add an instance of the structure, with the desired feature members set to VK_TRUE, to the pNext chain of VkDeviceCreateInfo when creating the VkDevice.
