C Specification
To query 16-bit storage features additionally supported call
vkGetPhysicalDeviceFeatures2 with a
VkPhysicalDevice16BitStorageFeatures structure included in the
pNext chain of its pFeatures parameter.
The VkPhysicalDevice16BitStorageFeatures 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 VkPhysicalDevice16BitStorageFeatures structure is defined as:
typedef struct VkPhysicalDevice16BitStorageFeatures {
VkStructureType sType;
void* pNext;
VkBool32 storageBuffer16BitAccess;
VkBool32 uniformAndStorageBuffer16BitAccess;
VkBool32 storagePushConstant16;
VkBool32 storageInputOutput16;
} VkPhysicalDevice16BitStorageFeatures;
or the equivalent
typedef VkPhysicalDevice16BitStorageFeatures VkPhysicalDevice16BitStorageFeaturesKHR;
Members
-
sTypeis the type of this structure. -
pNextisNULLor a pointer to an extension-specific structure.
Description
-
storageBuffer16BitAccessspecifies whether objects in theStorageBufferorPhysicalStorageBufferstorage class with theBlockdecoration can have 16-bit integer and 16-bit floating-point members. If this feature is not enabled, 16-bit integer or 16-bit floating-point members must not be used in such objects. This also specifies whether shader modules can declare theStorageBuffer16BitAccesscapability. -
uniformAndStorageBuffer16BitAccessspecifies whether objects in theUniformstorage class with theBlockdecoration and in theStorageBufferorPhysicalStorageBufferstorage class with the same decoration can have 16-bit integer and 16-bit floating-point members. If this feature is not enabled, 16-bit integer or 16-bit floating-point members must not be used in such objects. This also specifies whether shader modules can declare theUniformAndStorageBuffer16BitAccesscapability. -
storagePushConstant16specifies whether objects in thePushConstantstorage class can have 16-bit integer and 16-bit floating-point members. If this feature is not enabled, 16-bit integer or floating-point members must not be used in such objects. This also specifies whether shader modules can declare theStoragePushConstant16capability. -
storageInputOutput16specifies whether objects in theInputandOutputstorage classes can have 16-bit integer and 16-bit floating-point members. If this feature is not enabled, 16-bit integer or 16-bit floating-point members must not be used in such objects. This also specifies whether shader modules can declare theStorageInputOutput16capability.
