VkPhysicalDeviceRobustness2FeaturesEXT - Structure describing the out-of-bounds behavior for an implementation

Members

The members of the PhysicalDeviceRobustness2FeaturesEXT structure describe the following features:

Description

• robustBufferAccess2 indicates 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 of robustUniformBufferAccessSizeAlignment. Storage buffers must be bounds-checked to the range of the descriptor, where the range is rounded up to a multiple of robustStorageBufferAccessSizeAlignment. Out of bounds buffer loads will return zero values, and formatted loads will have (0,0,1) values inserted for missing G, B, or A components based on the format.

• robustImageAccess2 indicates whether image accesses are tightly bounds-checked against the dimensions of the image view. Out of bounds image loads will return zero values, with (0,0,1) values inserted for missing G, B, or A components based on the format.
• nullDescriptor indicates whether descriptors can be written with a NULL_HANDLE resource or view, which are considered valid to access and act as if the descriptor were bound to nothing.

If the PhysicalDeviceRobustness2FeaturesEXT structure is included in the pNext chain of PhysicalDeviceFeatures2, it is filled with values indicating whether each feature is supported.

Valid Usage

• If robustBufferAccess2 is enabled then robustBufferAccess must also be enabled

Valid Usage (Implicit)

• sType must be STRUCTURE_TYPE_PHYSICAL_DEVICE_ROBUSTNESS_2_FEATURES_EXT
