Description

This extension allows the application to query a 64-bit buffer device address value for a buffer, which can be used to access the buffer memory via the PhysicalStorageBufferEXT storage class in the GL_EXT_buffer_reference GLSL extension and SPV_EXT_physical_storage_buffer SPIR-V extension.

It also allows buffer device addresses to be provided by a trace replay tool, so that it matches the address used when the trace was captured.

Issues

1) Where is VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_BUFFER_ADDRESS_FEATURES_EXT and VkPhysicalDeviceBufferAddressFeaturesEXT?

RESOLVED: They were renamed as STRUCTURE_TYPE_PHYSICAL_DEVICE_BUFFER_DEVICE_ADDRESS_FEATURES_EXT and PhysicalDeviceBufferDeviceAddressFeaturesEXT accordingly for consistency. Even though, the old names can still be found in the generated header files for compatibility.

Synopsis

Documentation

data PhysicalDeviceBufferDeviceAddressFeaturesEXT Source #

VkPhysicalDeviceBufferDeviceAddressFeaturesEXT - Structure describing buffer address features that can be supported by an implementation

Members

This structure describes the following features:

Description

If the PhysicalDeviceBufferDeviceAddressFeaturesEXT structure is included in the pNext chain of the PhysicalDeviceFeatures2 structure passed to getPhysicalDeviceFeatures2, it is filled in to indicate whether each corresponding feature is supported. PhysicalDeviceBufferDeviceAddressFeaturesEXT can also be used in the pNext chain of DeviceCreateInfo to selectively enable these features.

Note

The PhysicalDeviceBufferDeviceAddressFeaturesEXT structure has the same members as the PhysicalDeviceBufferDeviceAddressFeatures structure, but the functionality indicated by the members is expressed differently. The features indicated by the PhysicalDeviceBufferDeviceAddressFeatures structure requires additional flags to be passed at memory allocation time, and the capture and replay mechanism is built around opaque capture addresses for buffer and memory objects.

Constructors

PhysicalDeviceBufferDeviceAddressFeaturesEXT 

Fields

  • bufferDeviceAddress :: Bool

    bufferDeviceAddress indicates that the implementation supports accessing buffer memory in shaders as storage buffers via an address queried from getBufferDeviceAddressEXT.

  • bufferDeviceAddressCaptureReplay :: Bool

    bufferDeviceAddressCaptureReplay indicates that the implementation supports saving and reusing buffer addresses, e.g. for trace capture and replay.

  • bufferDeviceAddressMultiDevice :: Bool

    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.

VkBufferDeviceAddressCreateInfoEXT - Request a specific address for a buffer

Description

If deviceAddress is zero, no specific address is requested.

If deviceAddress is not zero, then it must be an address retrieved from an identically created buffer on the same implementation. The buffer must also be bound to an identically created DeviceMemory object.

If this structure is not present, it is as if deviceAddress is zero.

Apps should avoid creating buffers with app-provided addresses and implementation-provided addresses in the same process, to reduce the likelihood of ERROR_INVALID_DEVICE_ADDRESS_EXT errors.
