C Specification
The VkPhysicalDeviceBufferDeviceAddressFeatures
structure is defined
as:
typedef struct VkPhysicalDeviceBufferDeviceAddressFeatures {
VkStructureType sType;
void* pNext;
VkBool32 bufferDeviceAddress;
VkBool32 bufferDeviceAddressCaptureReplay;
VkBool32 bufferDeviceAddressMultiDevice;
} VkPhysicalDeviceBufferDeviceAddressFeatures;
or the equivalent
typedef VkPhysicalDeviceBufferDeviceAddressFeatures VkPhysicalDeviceBufferDeviceAddressFeaturesKHR;
Members
The members of the VkPhysicalDeviceBufferDeviceAddressFeatures
structure describe the following features:
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
andrayTracing
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 VkPhysicalDeviceFeatures2, it is
filled with values indicating whether the feature is supported.
VkPhysicalDeviceBufferDeviceAddressFeatures
can also be included in
the pNext
chain of VkDeviceCreateInfo to enable features.
