VkPhysicalDeviceRobustness2FeaturesKHR(3)

Name

VkPhysicalDeviceRobustness2FeaturesKHR - Structure describing the out-of-bounds behavior for an implementation

C Specification

The VkPhysicalDeviceRobustness2FeaturesKHR structure is defined as:

// Provided by VK_KHR_robustness2
typedef struct VkPhysicalDeviceRobustness2FeaturesKHR {
    VkStructureType    sType;
    void*              pNext;
    VkBool32           robustBufferAccess2;
    VkBool32           robustImageAccess2;
    VkBool32           nullDescriptor;
} VkPhysicalDeviceRobustness2FeaturesKHR;

or the equivalent

// Provided by VK_EXT_robustness2
typedef VkPhysicalDeviceRobustness2FeaturesKHR VkPhysicalDeviceRobustness2FeaturesEXT;

Members

This structure describes the following features:

  • sType is a VkStructureType value identifying this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • robustBufferAccess2 enables Robust Buffer Access 2 guarantees for shader buffer accesses.

  • robustImageAccess2 enables Robust Image Access 2 guarantees for shader image accesses.

  • nullDescriptor indicates whether descriptors can be written with a VK_NULL_HANDLE resource or view, which are considered valid to access and act as if the descriptor were bound to nothing.

Description

If the VkPhysicalDeviceRobustness2FeaturesKHR 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 VkPhysicalDeviceRobustness2FeaturesKHR, 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.

Valid Usage

  • VUID-VkPhysicalDeviceRobustness2FeaturesKHR-robustBufferAccess2-04000
    If robustBufferAccess2 is enabled then robustBufferAccess must also be enabled

Valid Usage (Implicit)

  • VUID-VkPhysicalDeviceRobustness2FeaturesKHR-sType-sType
    sType must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_ROBUSTNESS_2_FEATURES_KHR
