VkPhysicalDeviceWorkgroupMemoryExplicitLayoutFeaturesKHR

The VkPhysicalDeviceWorkgroupMemoryExplicitLayoutFeaturesKHR structure is defined as:

typedef struct VkPhysicalDeviceWorkgroupMemoryExplicitLayoutFeaturesKHR {
    VkStructureType sType;
    void* pNext;
    VkBool32 workgroupMemoryExplicitLayout;
    VkBool32 workgroupMemoryExplicitLayoutScalarBlockLayout;
    VkBool32 workgroupMemoryExplicitLayout8BitAccess;
    VkBool32 workgroupMemoryExplicitLayout16BitAccess;
} VkPhysicalDeviceWorkgroupMemoryExplicitLayoutFeaturesKHR;

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.
• workgroupMemoryExplicitLayout indicates whether the implementation supports the SPIR-V WorkgroupMemoryExplicitLayoutKHR capability.
• workgroupMemoryExplicitLayoutScalarBlockLayout indicates whether the implementation supports scalar alignment for laying out Workgroup Blocks.
• workgroupMemoryExplicitLayout8BitAccess indicates whether objects in the Workgroup storage class with the Block decoration can have 8-bit integer members. If this feature is not enabled, 8-bit integer members must not be used in such objects. This also indicates whether shader modules can declare the WorkgroupMemoryExplicitLayout8BitAccessKHR capability.
• workgroupMemoryExplicitLayout16BitAccess indicates whether objects in the Workgroup storage class with the Block decoration can have 16-bit integer and 16-bit floating-point members. If this feature is not enabled, 16-bit integer or 16-bit floating-point members must not be used in such objects. This also indicates whether shader modules can declare the WorkgroupMemoryExplicitLayout16BitAccessKHR capability.

If the VkPhysicalDeviceWorkgroupMemoryExplicitLayoutFeaturesKHR 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 VkPhysicalDeviceWorkgroupMemoryExplicitLayoutFeaturesKHR, 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.
