If you believe that individual invalidations being called too often, you can lower the tunable: - /sys/debug/kernel/x86/tlb_single_page_flush_ceiling + /sys/kernel/debug/x86/tlb_single_page_flush_ceiling This will cause us to do the global flush for more cases. Lowering it to 0 will disable the use of the individual flushes. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
