C Specification
The VkPhysicalDevice8BitStorageFeatures structure is defined as:
// Provided by VK_VERSION_1_2
typedef struct VkPhysicalDevice8BitStorageFeatures {
VkStructureType sType;
void* pNext;
VkBool32 storageBuffer8BitAccess;
VkBool32 uniformAndStorageBuffer8BitAccess;
VkBool32 storagePushConstant8;
} VkPhysicalDevice8BitStorageFeatures;
or the equivalent
// Provided by VK_KHR_8bit_storage
typedef VkPhysicalDevice8BitStorageFeatures VkPhysicalDevice8BitStorageFeaturesKHR;
Members
This structure describes the following features:
-
sType
is a VkStructureType value identifying this structure. -
pNext
isNULL
or a pointer to a structure extending this structure.
Description
-
storageBuffer8BitAccess
indicates whether objects in theStorageBuffer
,ShaderRecordBufferKHR
, orPhysicalStorageBuffer
storage class with theBlock
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 theStorageBuffer8BitAccess
capability. -
uniformAndStorageBuffer8BitAccess
indicates whether objects in theUniform
storage class with theBlock
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 theUniformAndStorageBuffer8BitAccess
capability. -
storagePushConstant8
indicates whether objects in thePushConstant
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 theStoragePushConstant8
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.
If the application wishes to use a VkDevice with any features
described by VkPhysicalDevice8BitStorageFeatures
, 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.
