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 code:PhysicalStorageBufferEXT storage class in the
|

GLSL extension and

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.
