Yeah, I don't have any of those chips.. last I have is WSM-EP.
Anyway, perf_event_intel.c lists: 60,63,69,70,71 as being haswell
clients. Andi did all that, so if its wrong its on Intel anyway.
I'm still thinking we ought to make a big Intel classification function;
something that returns something like:
struct intel_part {
enum { client, ep, ex } type;
enum { core, core2, nhm, wsm, snb, ivb, hsw } gen;
};
And we can do things like:
if (ip.type == client && ip.gen >= snb)
And then we only have to fix up the one classification function with all
those stupid model numbers, instead of having them duplicated all over
the stinking place.
