C Specification
The VkPhysicalDevice16BitStorageFeatures structure is defined as:
// Provided by VK_VERSION_1_1
typedef struct VkPhysicalDevice16BitStorageFeatures {
VkStructureType sType;
void* pNext;
VkBool32 storageBuffer16BitAccess;
VkBool32 uniformAndStorageBuffer16BitAccess;
VkBool32 storagePushConstant16;
VkBool32 storageInputOutput16;
} VkPhysicalDevice16BitStorageFeatures;
or the equivalent
// Provided by VK_KHR_16bit_storage
typedef VkPhysicalDevice16BitStorageFeatures VkPhysicalDevice16BitStorageFeaturesKHR;
Description
-
sTypeis a VkStructureType value identifying this structure. -
pNextisNULLor a pointer to a structure extending this structure.
-
storageBuffer16BitAccessspecifies whether objects in theStorageBuffer,ShaderRecordBufferKHR, orPhysicalStorageBufferstorage 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 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.
If the VkPhysicalDevice16BitStorageFeatures 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.
VkPhysicalDevice16BitStorageFeatures can also be used in the pNext chain of
VkDeviceCreateInfo to selectively enable these features.
