Performance Counters on Pentium M |
|
|
I've done some searching, but have been unable to find userful information
Pentium M performance counters. There's plenty of good material on the
P-4, but not so much it seems for the P-M.
I'm trying to get a handle on the performance characteristics of a piece
of software I'm maintaining, and am interested in things like 'number of
L1 cache misses', 'pipeline flushes', etc. Is there any good programmatic
way to get this information out of a Pentium M? I know VTune is supposed
to do a lot, but this is a 'zero budget' kind of thing, and I don't need
anything near the level of control it offers.
If it matters, I'm doing this under Windows XP.
Thanks,
Mike

Pentium M is basically a P6 (Pentium Pro) family microprocessor.
(Still going strong after all these years!)
The IA-32 Intel Architecture Software Developer¢s Manual Volume 3:
System Programming Guide, appendix A describes this.
There is even a section A.2 PERFORMANCE MONITORING EVENTS FOR INTEL
PENTIUM M PROCESSORS |

That section is a delta so I guess that any PMON software for the ppro
should continue to work on the Pentium M.

And so does my original Byte article from June 1994.
I.e. this has been well-known for a long time now.

Maybe it's the small block Chevy of the computing world. :-)

The Pentium Pro was introduced in October 1995. Are you sure your
article is not about the Pentium (P5)?

Sorry, I was unclear. :-(
Yes, my article was indeed about the P5 ("Pentium Secrets"), the key
point was that even though the set of counters available have changed
quite a bit, the actual programming interface has been unchanged since
my article.
I have also been told that this article was one of the reasons Intel
decided to actually document the counters, starting with the P6.
