14  This extension allows the application to query a 64-bit buffer device
15  address value for a buffer, which can be used to access the buffer memory
16  via the code:PhysicalStorageBufferEXT storage class in the
17  https://github.com/KhronosGroup/GLSL/blob/master/extensions/ext/GLSL_EXT_buffer_reference.txt[`GL_EXT_buffer_reference`]
18  GLSL extension and

20  SPIR-V extension.

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