C Specification
The VkPhysicalDeviceBufferDeviceAddressFeaturesEXT structure is
defined as:
// Provided by VK_EXT_buffer_device_address
typedef struct VkPhysicalDeviceBufferDeviceAddressFeaturesEXT {
VkStructureType sType;
void* pNext;
VkBool32 bufferDeviceAddress;
VkBool32 bufferDeviceAddressCaptureReplay;
VkBool32 bufferDeviceAddressMultiDevice;
} VkPhysicalDeviceBufferDeviceAddressFeaturesEXT;
// Provided by VK_EXT_buffer_device_address
typedef VkPhysicalDeviceBufferDeviceAddressFeaturesEXT VkPhysicalDeviceBufferAddressFeaturesEXT;
Members
This structure describes the following features:
-
sTypeis a VkStructureType value identifying this structure. -
pNextisNULLor a pointer to a structure extending this structure. -
bufferDeviceAddressindicates that the implementation supports accessing buffer memory in shaders as storage buffers via an address queried from vkGetBufferDeviceAddressEXT. -
bufferDeviceAddressCaptureReplayindicates that the implementation supports saving and reusing buffer 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.
Description
If the VkPhysicalDeviceBufferDeviceAddressFeaturesEXT 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 VkPhysicalDeviceBufferDeviceAddressFeaturesEXT, 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.
