Hi,
I need to make detailed TLB miss measurements under Mac OS X (10.6.3) with a
Core 2 Duo processor
and was thinking of using the CPU's performance counters.
Q1. Is there a CPC or equivalent provider on the x86/mac ? I don't see
anything obvious related
to the perf. counters in the probe list, or via the Instruments app.
Q2. Or is there some other way of getting the count of I/D TLB misses
without using performance counters ?
If neither of these approaches work with dtrace, what tools do folks
recommend for these measurements --
(I'm looking at Shark from the Chud tools currently).
thanks,
Ray
