Looking at the doc this CPU require a full set of PMC as the list of event are different.
So this mean full manpage, full event list, …

Doc:
"
The events in Table 19-3 apply to
processors with CPUID signature of DisplayFamily_DisplayModel encoding with the
following values: 06_2AH and 06_2DH. The events in Table 19-4 apply to processors
with CPUID signature 06_2AH. The events in Table 19-5 apply to processors with
CPUID signature 06_2DH.
"

Required change will be the same as this commit if you want to look at it:
