VK_EXT_buffer_device_address(3) Manual Page

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.

1) Where is VK_STRUCTURE_TYPE_PHYSICAL_DEVICE_BUFFER_ADDRESS_FEATURES_EXT and VkPhysicalDeviceBufferAddressFeaturesEXT?

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