C Specification
The VkPhysicalDeviceBufferDeviceAddressFeaturesKHR structure is
defined as:
typedef struct VkPhysicalDeviceBufferDeviceAddressFeaturesKHR {
VkStructureType sType;
void* pNext;
VkBool32 bufferDeviceAddress;
VkBool32 bufferDeviceAddressCaptureReplay;
VkBool32 bufferDeviceAddressMultiDevice;
} VkPhysicalDeviceBufferDeviceAddressFeaturesKHR;
Members
The members of the VkPhysicalDeviceBufferDeviceAddressFeaturesKHR
structure describe the following features:
Description
-
bufferDeviceAddressindicates that the implementation supports accessing buffer memory in shaders as storage buffers via an address queried from vkGetBufferDeviceAddressKHR. -
bufferDeviceAddressCaptureReplayindicates that the implementation supports saving and reusing buffer and device addresses, e.g. for trace capture and replay. -
bufferDeviceAddressMultiDeviceindicates that the implementation supports thebufferDeviceAddressfeature for logical devices created with multiple physical devices. If this feature is not supported, buffer addresses must not be queried on a logical device created with more than one physical device.

Note
|
See vkGetBufferDeviceAddressKHR for more information.
If the VkPhysicalDeviceBufferDeviceAddressFeaturesKHR structure is
included in the pNext chain of VkPhysicalDeviceFeatures2, it is
filled with values indicating whether the feature is supported.
VkPhysicalDeviceBufferDeviceAddressFeaturesKHR can also be included
in the pNext chain of VkDeviceCreateInfo to enable features.
