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?
