C Specification

The VkPhysicalDeviceVariablePointersFeatures structure is defined as:

// Provided by VK_VERSION_1_1
typedef struct VkPhysicalDeviceVariablePointersFeatures {
    VkStructureType    sType;
    void*              pNext;
    VkBool32           variablePointersStorageBuffer;
    VkBool32           variablePointers;
} VkPhysicalDeviceVariablePointersFeatures;
// Provided by VK_VERSION_1_1
typedef VkPhysicalDeviceVariablePointersFeatures VkPhysicalDeviceVariablePointerFeatures;

or the equivalent

// Provided by VK_KHR_variable_pointers
typedef VkPhysicalDeviceVariablePointersFeatures VkPhysicalDeviceVariablePointersFeaturesKHR;
// Provided by VK_KHR_variable_pointers
typedef VkPhysicalDeviceVariablePointersFeatures VkPhysicalDeviceVariablePointerFeaturesKHR;

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.

Description

  • 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.

If the VkPhysicalDeviceVariablePointersFeatures 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 VkPhysicalDeviceVariablePointersFeatures, 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
  • VUID-VkPhysicalDeviceVariablePointersFeatures-variablePointers-01431
    If variablePointers is enabled then variablePointersStorageBuffer must also be enabled

Valid Usage (Implicit)
  • VUID-VkPhysicalDeviceVariablePointersFeatures-sType-sType
    sType must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_VARIABLE_POINTERS_FEATURES
