Add some initial RAS documentation. The expectation is for this to collect, among others, all the user-visible features for interaction with the RAS features of the kernel.

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>
