C Specification
To query 8-bit storage features additionally supported call
vkGetPhysicalDeviceFeatures2 with a
VkPhysicalDevice8BitStorageFeatures
structure included in the
pNext
chain of its pFeatures
parameter.
The VkPhysicalDevice8BitStorageFeatures
structure can also be
included in the pNext
chain of a VkDeviceCreateInfo structure,
in which case it controls which additional features are enabled in the
device.
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
-
sType
is the type of 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.
