C Specification

The VkPhysicalDeviceVariablePointerFeatures structure is defined as:

typedef struct VkPhysicalDeviceVariablePointerFeatures {
    VkStructureType    sType;
    void*              pNext;
    VkBool32           variablePointersStorageBuffer;
    VkBool32           variablePointers;
} VkPhysicalDeviceVariablePointerFeatures;

or the equivalent

typedef VkPhysicalDeviceVariablePointerFeatures VkPhysicalDeviceVariablePointerFeaturesKHR;

Members

The members of the VkPhysicalDeviceVariablePointerFeatures structure describe the following features:

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 VkPhysicalDeviceVariablePointerFeatures structure is included in the pNext chain of VkPhysicalDeviceFeatures2, it is filled with values indicating whether each feature is supported. VkPhysicalDeviceVariablePointerFeatures can also be used in the pNext chain of VkDeviceCreateInfo to enable the features.

Valid Usage
  • If variablePointers is enabled then variablePointersStorageBuffer must also be enabled.

Valid Usage (Implicit)
  • sType must be VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_VARIABLE_POINTER_FEATURES
