Errata are defined using the AMD_LEGACY_ERRATUM() or AMD_OSVW_ERRATUM() macros. The latter is intended for newer errata that have an OSVW id assigned, which it takes as first argument. Both take a variable number of family-specific model-stepping ranges created by AMD_MODEL_RANGE(). Iff an erratum has an OSVW id, OSVW is available on the CPU, and the OSVW id is known to the hardware, it is used to determine whether an erratum is present. Otherwise, the model-stepping ranges are matched against the current CPU to find out whether the erratum applies. For certain special errata, the code using this framework might have to conduct further checks to make sure an erratum is really (not) present.
