+=====================================================
+
+This documents different aspects of the RAS functionality present in the
+kernel.
+
+Error decoding
+---------------
+
+* x86
+
+Error decoding on AMD systems should be done using the rasdaemon tool:
+https://github.com/mchehab/rasdaemon/
+
+While the daemon is running, it would automatically log and decode
+errors. If not, one can still decode such errors by supplying the
+hardware information from the error::
+
+        $ rasdaemon -p --status <STATUS> --ipid <IPID> --smca
+
+Also, the user can pass particular family and model to decode the error
+string::
+
+        $ rasdaemon -p --status <STATUS> --ipid <IPID> --smca --family <CPU Family> --model <CPU Model> --bank <BANK_NUM>
