VkPhysicalDeviceShader64BitIndexingFeaturesEXT(3)

# VkPhysicalDeviceShader64BitIndexingFeaturesEXT(3) Manual Page

## Name

VkPhysicalDeviceShader64BitIndexingFeaturesEXT - Structure describing 64-bit indexing features that can be supported by an implementation

## C Specification

The `VkPhysicalDeviceShader64BitIndexingFeaturesEXT` structure is defined as:

    // Provided by VK_EXT_shader_64bit_indexing
    typedef struct VkPhysicalDeviceShader64BitIndexingFeaturesEXT {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           shader64BitIndexing;
    } VkPhysicalDeviceShader64BitIndexingFeaturesEXT;

## Members

This structure describes the following features:

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

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

- `shader64BitIndexing` indicates that the implementation supports using 64-bit address calculations for indexing cooperative matrices, cooperative vectors, storage buffers, and physical storage buffers.

## Description

If the `VkPhysicalDeviceShader64BitIndexingFeaturesEXT` 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 `VkPhysicalDeviceShader64BitIndexingFeaturesEXT`, 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-VkPhysicalDeviceShader64BitIndexingFeaturesEXT-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_SHADER_64_BIT_INDEXING_FEATURES_EXT

Structure Chaining

Extends the structures

  - VkDeviceCreateInfo

  - VkPhysicalDeviceFeatures2
