[AMD Official Use Only - General] Hello Boris, >> Yes, I will be adding a check for CPU family/model as following : >Why if the PPR is already kinda spelling the already architectural pieces of the RMP entry? >"In order to assist software" it says. The PPR specifies select portions of the RMP entry format for a specific core/platform. Therefore, the complete struct rmpentry definition is non-architectural. As per PPR, software should not rely on any field definitions not specified in this table and the format of an RMP entry may change in future processors. >So you call the specified ones by their name and the rest is __rsvd. >No need for model checks at all. >Right? But we can't use this struct on a core/platform which has a different layout, so aren't the model checks required ? Thanks, Ashish
