# VkPhysicalDeviceMaintenance6Features(3) Manual Page

## Name

VkPhysicalDeviceMaintenance6Features - Structure describing whether the implementation supports maintenance6 functionality

Loading… please wait.

## C Specification

The `VkPhysicalDeviceMaintenance6Features` structure is defined as:

    // Provided by VK_VERSION_1_4
    typedef struct VkPhysicalDeviceMaintenance6Features {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           maintenance6;
    } VkPhysicalDeviceMaintenance6Features;

or the equivalent

    // Provided by VK_KHR_maintenance6
    typedef VkPhysicalDeviceMaintenance6Features VkPhysicalDeviceMaintenance6FeaturesKHR;

## Members

This structure describes the following feature:

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

## Description

- `maintenance6` indicates that the implementation supports the following:

  - VK_NULL_HANDLE can be used when binding an index buffer

  - VkBindMemoryStatus can be included in the `pNext` chain of the VkBindBufferMemoryInfo and VkBindImageMemoryInfo structures, enabling applications to retrieve VkResult values for individual memory binding operations.

  - VkPhysicalDeviceMaintenance6Properties::`blockTexelViewCompatibleMultipleLayers` property to indicate that the implementation supports creating image views with `VK_IMAGE_CREATE_BLOCK_TEXEL_VIEW_COMPATIBLE_BIT` where the `layerCount` member of `subresourceRange` is greater than `1`.

  - VkPhysicalDeviceMaintenance6Properties::`maxCombinedImageSamplerDescriptorCount` property which indicates the maximum descriptor size required for any format that requires a sampler Y′CBCR conversion supported by the implementation.

  - A VkPhysicalDeviceMaintenance6Properties::`fragmentShadingRateClampCombinerInputs` property which indicates whether the implementation clamps the inputs to fragment shading rate combiner operations.

If the `VkPhysicalDeviceMaintenance6Features` 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 `VkPhysicalDeviceMaintenance6Features`, 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 (Implicit)

- VUID-VkPhysicalDeviceMaintenance6Features-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_MAINTENANCE_6_FEATURES`
