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 -------------- next part -------------- An HTML attachment was scrubbed...
