Class VkPhysicalDeviceBufferDeviceAddressFeaturesEXT

  • All Implemented Interfaces:
    java.lang.AutoCloseable, NativeResource, Pointer
    Direct Known Subclasses:
    VkPhysicalDeviceBufferAddressFeaturesEXT

    public class VkPhysicalDeviceBufferDeviceAddressFeaturesEXT
    extends Struct
    implements NativeResource
    Structure describing buffer address features that can be supported by an implementation.
    Description
    Note

    bufferDeviceAddressMultiDevice exists to allow certain legacy platforms to be able to support bufferDeviceAddress without needing to support shared GPU virtual addresses for multi-device configurations.

    See GetBufferDeviceAddressEXT for more information.

    If the VkPhysicalDeviceBufferDeviceAddressFeaturesEXT structure is included in the pNext chain of VkPhysicalDeviceFeatures2, it is filled with values indicating whether the feature is supported. VkPhysicalDeviceBufferDeviceAddressFeaturesEXT can also be used in the pNext chain of VkDeviceCreateInfo to enable features.

    Valid Usage (Implicit)

    Member documentation

    • bufferDeviceAddress – indicates that the implementation supports accessing buffer memory in shaders as storage buffers via an address queried from GetBufferDeviceAddressEXT.
    • bufferDeviceAddressCaptureReplay – indicates that the implementation supports saving and reusing buffer addresses, e.g. for trace capture and replay.
    • bufferDeviceAddressMultiDevice – indicates that the implementation supports the bufferDeviceAddress 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.

    Layout

    
     struct VkPhysicalDeviceBufferDeviceAddressFeaturesEXT {
         VkStructureType sType;
         void * pNext;
         VkBool32 bufferDeviceAddress;
         VkBool32 bufferDeviceAddressCaptureReplay;
         VkBool32 bufferDeviceAddressMultiDevice;
     }
