perf stat -e \{r1000248,r148\} -- sleep 1

 Performance counter stats for 'sleep 1':

             9,605      r1000248
           553,201      r148


Intel Ivy Bridge EP machine (family = 6, model = 62),
kernel/perf version 4.3.0

The Intel 64 and IA-32 Architectures Software Developer's
Manual, vol-3B, part-2 agrees with the download.01.org's
json file on the fact that r0148 is limited to the counter
2 only on both IVB and HSW.

But I can't find any reference about the r1000248 event
in the Intel Manual. Vince, am I missing something?

Anyway, shouldn't it behave the same on IVB and HSW?
