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.
