# VkPhysicalDevice8BitStorageFeaturesKHR(3) Manual Page

## Name

VkPhysicalDevice8BitStorageFeaturesKHR - Structure describing features supported by VK_KHR_8bit_storage

## C Specification

To query 8-bit storage features additionally supported call vkGetPhysicalDeviceFeatures2 with a `VkPhysicalDevice8BitStorageFeaturesKHR` structure included in the `pNext` chain of its `pFeatures` parameter. The `VkPhysicalDevice8BitStorageFeaturesKHR` structure can also be in the `pNext` chain of a VkDeviceCreateInfo structure, in which case it controls which additional features are enabled in the device.

The VkPhysicalDevice8BitStorageFeaturesKHR structure is defined as:

    typedef struct VkPhysicalDevice8BitStorageFeaturesKHR {
        VkStructureType    sType;
        void*              pNext;
        VkBool32           storageBuffer8BitAccess;
        VkBool32           uniformAndStorageBuffer8BitAccess;
        VkBool32           storagePushConstant8;
    } VkPhysicalDevice8BitStorageFeaturesKHR;

## Members

- `sType` is the type of this structure.

- `pNext` is `NULL` or a pointer to an extension-specific structure.

- `storageBuffer8BitAccess` indicates whether objects in the `StorageBuffer` or `PhysicalStorageBufferEXT` 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 and in the `StorageBuffer` or `PhysicalStorageBufferEXT` storage class with the same 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.

## Description

Valid Usage (Implicit)

- `sType` must be `VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_8BIT_STORAGE_FEATURES_KHR`
