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>
