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
-
bufferDeviceAddress
indicates that the implementation supports accessing buffer memory in shaders as storage buffers via an address queried from vkGetBufferDeviceAddressKHR. -
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
feature 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 used in
the pNext
chain of VkDeviceCreateInfo to enable features.
