FP_COMP_OPS_EXE on Silvermont?

4f0drlp7eyj3 — Tue, 04 Mar 2014 01:53:01 GMT

Hi,

Is there an equivalent of the FP_COMP_OPS_EXE family of events (.X87, .SSE_FP_PACKED_DOUBLE, etc.) for Silvermont chips? I am trying to use Linux "perf" to get at performance statistics of a scientific code, but from the non-architectural events listed in Table 19-18 of the Software Developer's Manual (Vol. 3), I don't see anything. If there isn't, does anyone have advice on counting FlOps and integer ops on Silvermont?

Thanks,

Chris

Silvermont Performance Monitoring events do not include a FLOPS event and I believe the closest you are going to get on Silvermont are the events:

1. UOPS_RETIRED.X87

2. UOPS_RETIRED.MUL

3. UOPS_RETIRED.DIV
