## Name

VkPhysicalDeviceVulkan11Features - Structure describing the Vulkan 1.1 features that can be supported by an implementation

## C Specification

The `VkPhysicalDeviceVulkan11Features` structure is defined as:

    typedef struct VkPhysicalDeviceVulkan11Features {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           storageBuffer16BitAccess;
        VkBool32           uniformAndStorageBuffer16BitAccess;
        VkBool32           storagePushConstant16;
        VkBool32           storageInputOutput16;
        VkBool32           multiview;
        VkBool32           multiviewGeometryShader;
        VkBool32           multiviewTessellationShader;
        VkBool32           variablePointersStorageBuffer;
        VkBool32           variablePointers;
        VkBool32           protectedMemory;
        VkBool32           samplerYcbcrConversion;
        VkBool32           shaderDrawParameters;
    } VkPhysicalDeviceVulkan11Features;

## Members

The members of the `VkPhysicalDeviceVulkan11Features` structure describe the following features:

## Description

- `storageBuffer16BitAccess` specifies whether objects in the `StorageBuffer` 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` 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)

- `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_VULKAN_1_1_FEATURES`
