VkPhysicalDevice8BitStorageFeatures

The VkPhysicalDevice8BitStorageFeatures structure is defined as:

typedef struct VkPhysicalDevice8BitStorageFeatures {
    VkStructureType sType;
    void* pNext;
    VkBool32 storageBuffer8BitAccess;
    VkBool32 uniformAndStorageBuffer8BitAccess;
    VkBool32 storagePushConstant8;
} VkPhysicalDevice8BitStorageFeatures;

or the equivalent

typedef VkPhysicalDevice8BitStorageFeatures VkPhysicalDevice8BitStorageFeaturesKHR;

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.
• storageBuffer8BitAccess indicates whether objects in the StorageBuffer, ShaderRecordBufferKHR, or PhysicalStorageBuffer 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 StorageBuffer8BitAccess capability.
• uniformAndStorageBuffer8BitAccess indicates whether objects in the Uniform 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 UniformAndStorageBuffer8BitAccess capability.
• storagePushConstant8 indicates whether objects in the PushConstant storage class 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 StoragePushConstant8 capability.

If the VkPhysicalDevice8BitStorageFeatures 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. VkPhysicalDevice8BitStorageFeatures can also be used in the pNext chain of VkDeviceCreateInfo to selectively enable these features.
