Also, for completeness: running the PRD daemon is only required on machines that have the "diagnostics" OPAL firmware feature. At present (and this is unlikely to change), the set of these machines is equivalent to the set of OpenPOWER machines.

To be exact, this is indicated on a running system by the presence of a "diagnostics" device-tree node under the firmware one, which has a compatible value of "ibm,opal-prd".
