You wouldn't happen to know the equivalent counter event to a tlb_flush_mmu() for a PIII by any chance, would you? :). I've checked op_help and only found the ITLB_MISS. I look at the L2_* related cpu counters but can't find a TLB flush counter. I'm reading through Appendix A of the IA-32 Architecture Vol 3 manual (it's actually very interesting), but I haven't found it either so far. Do I have to check for the INVLPG instructions?
