https://community.intel.com/t5/Analyzers/More-information-on-PIII-counters/m-p/993100#M11450 The info on P4 counters is quite nice -- is there anywhere I can get such info on PIII counters? I've checked all of the hardware manuals I can get my hands on, but the descriptions are not extremely clear.<BR /><BR />If anyone knows, here are some particular questions, the answers to which will at least get me started (if there is a forum for these questions, please let me know):<BR /><BR />1. A 'highly correlated' counter is correlated to what, <BR /> exactly? (e.g. 'L2 Cache Request Misses (highly <BR /> correlated)')<BR /><BR />2. Is there a way to count the number of D-TLB misses?<BR /> I assume that 'External Bus Memory References' <BR /> includes I- and D-TLB misses (including PDE and PTE)<BR /> and L2 misses, but it is not clear what else this<BR /> counter tallies.<BR /><BR />I am perfectly happy with the response 'RTFM', as long as <BR />it is included with a pointer to the right one. :-)<BR /><BR />BTW: I am using Redhat 7.3, with some components <BR /> "borrowed" from 8.0. (the GNU compilers, in <BR /> particular).<BR /><BR />Cheers,<BR />Demian M.
