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
isNULL
or a pointer to an extension-specific structure. -
storageBuffer8BitAccess
indicates whether objects in theStorageBuffer
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 and in theStorageBuffer
orPhysicalStorageBuffer
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 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.
