+                This property is a binary blob that contains the result of the

+                This custom interface is needed (instead of using the generic
+                Linux user-space PCI mapping) because the amount of internal
+                memory is huge (>32GB) and reading it via the PCI bar will take
+                a very long time.
+                This interface doesn't support concurrency in the same device.
+                In GAUDI and GOYA, this action can cause undefined behavior
+                in case the it is done while the device is executing user
+                workloads.
