C Specification
The VkPhysicalDeviceBufferDeviceAddressFeatures
structure is defined
as:
// Provided by VK_VERSION_1_2
typedef struct VkPhysicalDeviceBufferDeviceAddressFeatures {
VkStructureType sType;
void* pNext;
VkBool32 bufferDeviceAddress;
VkBool32 bufferDeviceAddressCaptureReplay;
VkBool32 bufferDeviceAddressMultiDevice;
} VkPhysicalDeviceBufferDeviceAddressFeatures;
or the equivalent
// Provided by VK_KHR_buffer_device_address
typedef VkPhysicalDeviceBufferDeviceAddressFeatures VkPhysicalDeviceBufferDeviceAddressFeaturesKHR;
Members
This structure describes the following features:
-
sType
is a VkStructureType value identifying this structure. -
pNext
isNULL
or a pointer to a structure extending this structure.
Description
-
bufferDeviceAddress
indicates that the implementation supports accessing buffer memory in shaders as storage buffers via an address queried from vkGetBufferDeviceAddress. -
bufferDeviceAddressCaptureReplay
indicates that the implementation supports saving and reusing buffer and device addresses, e.g. for trace capture and replay. -
bufferDeviceAddressMultiDevice
indicates that the implementation supports thebufferDeviceAddress
,rayTracingPipeline
andrayQuery
features for logical devices created with multiple physical devices. If this feature is not supported, buffer and acceleration structure addresses must not be queried on a logical device created with more than one physical device.
Note

See vkGetBufferDeviceAddress for more information.
If the VkPhysicalDeviceBufferDeviceAddressFeatures
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.
If the application wishes to use a VkDevice with any features
described by VkPhysicalDeviceBufferDeviceAddressFeatures
, it must add an instance of the structure,
with the desired feature members set to VK_TRUE
, to the pNext
chain of VkDeviceCreateInfo when creating the VkDevice.
