+kmemdump
+==========================
+
+This document provides information about the kmemdump feature.
+
+Overview
+========
+
+kmemdump is a mechanism that allows any driver or producer to register a
+chunk of memory into kmemdump, to be used at a later time for a specific
+purpose like debugging or memory dumping.
+
+kmemdump allows a backend to be connected, this backend interfaces a
+specific hardware that can debug or dump the memory registered into
+kmemdump.
