} VkPhysicalDeviceVulkan11Features;

Members

The members of the VkPhysicalDeviceVulkan11Features structure describe the following features:

Description

  • storageBuffer16BitAccess specifies whether objects in the StorageBuffer, ShaderRecordBufferKHR, or PhysicalStorageBuffer storage class with the Block decoration can have 16-bit integer and 16-bit floating-point members. If this feature is not enabled, 16-bit integer or 16-bit floating-point members must not be used in such objects. This also specifies whether shader modules can declare the StorageBuffer16BitAccess capability.

  • uniformAndStorageBuffer16BitAccess specifies whether objects in the Uniform storage class with the Block decoration and in the StorageBuffer, ShaderRecordBufferKHR, or PhysicalStorageBuffer storage class with the same decoration can have 16-bit integer and 16-bit floating-point members. If this feature is not enabled, 16-bit integer or 16-bit floating-point members must not be used in such objects. This also specifies whether shader modules can declare the UniformAndStorageBuffer16BitAccess capability.

  • storagePushConstant16 specifies whether objects in the PushConstant storage class can have 16-bit integer and 16-bit floating-point members. If this feature is not enabled, 16-bit integer or floating-point members must not be used in such objects. This also specifies whether shader modules can declare the StoragePushConstant16 capability.

  • storageInputOutput16 specifies whether objects in the Input and Output storage classes can have 16-bit integer and 16-bit floating-point members. If this feature is not enabled, 16-bit integer or 16-bit floating-point members must not be used in such objects. This also specifies whether shader modules can declare the StorageInputOutput16 capability.

  • multiview specifies whether the implementation supports multiview rendering within a render pass. If this feature is not enabled, the view mask of each subpass must always be zero.

  • multiviewGeometryShader specifies whether the implementation supports multiview rendering within a render pass, with geometry shaders. If this feature is not enabled, then a pipeline compiled against a subpass with a non-zero view mask must not include a geometry shader.

  • multiviewTessellationShader specifies whether the implementation supports multiview rendering within a render pass, with tessellation shaders. If this feature is not enabled, then a pipeline compiled against a subpass with a non-zero view mask must not include any tessellation shaders.

  • variablePointersStorageBuffer specifies whether the implementation supports the SPIR-V VariablePointersStorageBuffer capability. When this feature is not enabled, shader modules must not declare the SPV_KHR_variable_pointers extension or the VariablePointersStorageBuffer capability.

  • variablePointers specifies whether the implementation supports the SPIR-V VariablePointers capability. When this feature is not enabled, shader modules must not declare the VariablePointers capability.

  • protectedMemory specifies whether protected memory is supported.

  • samplerYcbcrConversion specifies whether the implementation supports sampler Y′CBCR conversion. If samplerYcbcrConversion is VK_FALSE, sampler Y′CBCR conversion is not supported, and samplers using sampler Y′CBCR conversion must not be used.

  • shaderDrawParameters specifies whether shader draw parameters are supported.

If the VkPhysicalDeviceVulkan11Features structure is included in the pNext chain of VkPhysicalDeviceFeatures2, it is filled with values indicating whether each feature is supported. VkPhysicalDeviceVulkan11Features can also be used in the pNext chain of VkDeviceCreateInfo to enable the features.

Valid Usage (Implicit)
  • VUID-VkPhysicalDeviceVulkan11Features-sType-sType
    sType must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_VULKAN_1_1_FEATURES
