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:
typedef struct VkPhysicalDevice8BitStorageFeatures {
VkStructureType sType;
void* pNext;
VkBool32 storageBuffer8BitAccess;
VkBool32 uniformAndStorageBuffer8BitAccess;
VkBool32 storagePushConstant8;
} VkPhysicalDevice8BitStorageFeatures;
or the equivalent
typedef VkPhysicalDevice8BitStorageFeatures VkPhysicalDevice8BitStorageFeaturesKHR;
Members
-
sTypeis the type of this structure. -
pNextisNULLor a pointer to an extension-specific structure.
Description
-
storageBuffer8BitAccessindicates whether objects in theStorageBufferorPhysicalStorageBufferstorage class with theBlockdecoration 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 theStorageBuffer8BitAccesscapability. -
uniformAndStorageBuffer8BitAccessindicates whether objects in theUniformstorage class with theBlockdecoration and in theStorageBufferorPhysicalStorageBufferstorage 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 theUniformAndStorageBuffer8BitAccesscapability. -
storagePushConstant8indicates whether objects in thePushConstantstorage 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 theStoragePushConstant8capability.
