VkPhysicalDeviceRobustness2FeaturesKHR

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

The VkPhysicalDeviceRobustness2FeaturesKHR structure is defined as:

typedef struct VkPhysicalDeviceRobustness2FeaturesKHR {
    VkStructureType sType;
    void* pNext;
    VkBool32 robustBufferAccess2;
    VkBool32 robustImageAccess2;
    VkBool32 nullDescriptor;
} VkPhysicalDeviceRobustness2FeaturesKHR;
typedef VkPhysicalDeviceRobustness2FeaturesKHR VkPhysicalDeviceRobustness2FeaturesEXT;

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.

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
