C Specification

The VkPhysicalDeviceZeroInitializeWorkgroupMemoryFeaturesKHR structure is defined as:

// Provided by VK_KHR_zero_initialize_workgroup_memory
typedef struct VkPhysicalDeviceZeroInitializeWorkgroupMemoryFeaturesKHR {
    VkStructureType    sType;
    void*              pNext;
    VkBool32           shaderZeroInitializeWorkgroupMemory;
} VkPhysicalDeviceZeroInitializeWorkgroupMemoryFeaturesKHR;


The member of the VkPhysicalDeviceZeroInitializeWorkgroupMemoryFeaturesKHR structure describe the following feature:


  • shaderZeroInitializeWorkgroupMemory specifies whether the implementation supports initializing a variable in Workgroup storage class.

If the VkPhysicalDeviceZeroInitializeWorkgroupMemoryFeaturesKHR structure is included in the pNext chain of VkPhysicalDeviceFeatures2, it is filled with a value indicating whether the feature is supported. VkPhysicalDeviceZeroInitializeWorkgroupMemoryFeaturesKHR can also be included in the pNext chain of VkDeviceCreateInfo to enable the features.

Valid Usage (Implicit)
  • VUID-VkPhysicalDeviceZeroInitializeWorkgroupMemoryFeaturesKHR-sType-sType
