C Specification
The VkPhysicalDeviceRobustness2FeaturesEXT structure is defined as:
// Provided by VK_EXT_robustness2
typedef struct VkPhysicalDeviceRobustness2FeaturesEXT {
VkStructureType sType;
void* pNext;
VkBool32 robustBufferAccess2;
VkBool32 robustImageAccess2;
VkBool32 nullDescriptor;
} VkPhysicalDeviceRobustness2FeaturesEXT;Members
This structure describes the following features:
-
sTypeis a VkStructureType value identifying this structure. -
pNextisNULLor a pointer to a structure extending this structure. -
robustBufferAccess2indicates whether buffer accesses are tightly bounds-checked against the range of the descriptor. Uniform buffers must be bounds-checked to the range of the descriptor, where the range is rounded up to a multiple ofrobustUniformBufferAccessSizeAlignment. Storage buffers must be bounds-checked to the range of the descriptor, where the range is rounded up to a multiple ofrobustStorageBufferAccessSizeAlignment. Out of bounds buffer loads will return zero values, and image load, sample, and atomic operations from texel buffers will have (0,0,1) values inserted for missing G, B, or A components based on the format. -
robustImageAccess2indicates whether image accesses are tightly bounds-checked against the dimensions of the image view. Out of bounds image load, sample, and atomic operations from images will return zero values, with (0,0,1) values inserted for missing G, B, or A components based on the format. -
nullDescriptorindicates 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 VkPhysicalDeviceRobustness2FeaturesEXT 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.
VkPhysicalDeviceRobustness2FeaturesEXT can also be used in the pNext chain of
VkDeviceCreateInfo to selectively enable these features.
