# VkPhysicalDeviceMaintenance9PropertiesKHR(3) Manual Page

## Name

VkPhysicalDeviceMaintenance9PropertiesKHR - Structure describing various implementation-defined properties introduced with VK_KHR_maintenance9

Loading… please wait.

## C Specification

The `VkPhysicalDeviceMaintenance9PropertiesKHR` structure is defined as:

    // Provided by VK_KHR_maintenance9
    typedef struct VkPhysicalDeviceMaintenance9PropertiesKHR {
        VkStructureType                     sType;
        void*                               pNext;
        VkBool32                            image2DViewOf3DSparse;
        VkDefaultVertexAttributeValueKHR    defaultVertexAttributeValue;
    } VkPhysicalDeviceMaintenance9PropertiesKHR;

## Members

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

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

- If the `image2DViewOf3D` feature is enabled, `image2DViewOf3DSparse` indicates whether the implementation supports binding a slice of a sparse 3D image to a 2D image view.

- `defaultVertexAttributeValue` is a VkDefaultVertexAttributeValueKHR that indicates what value the implementation will return when the vertex shader reads unbound vertex attributes. Unbound attributes are those that have no corresponding VkVertexInputAttributeDescription::`location` defined in the bound graphics pipeline or no corresponding VkVertexInputAttributeDescription2EXT::`location` set by the most recent call to vkCmdSetVertexInputEXT when the state is dynamic .

## Description

If the `VkPhysicalDeviceMaintenance9PropertiesKHR` structure is included in the `pNext` chain of the VkPhysicalDeviceProperties2 structure passed to vkGetPhysicalDeviceProperties2, it is filled in with each corresponding implementation-dependent property.

Valid Usage (Implicit)

- VUID-VkPhysicalDeviceMaintenance9PropertiesKHR-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_MAINTENANCE_9_PROPERTIES_KHR`
