Use pmap_TLB_invalidate instead of invltlb_1pg to eliminate unnecessary IPIs. pmap_remove, pmap_protect and pmap_remove_pages: Use pmap_TLB_invalidate_all instead of invltlb to eliminate unnecessary IPIs. pmap_copy: Use cpu_invltlb instead of invltlb when updating APTDpde. pmap_changebit: Rather than deleting the unused "set bit" option (which may be useful later), make pmap_changebit an inline that is used by the new pmap_clearbit procedure. Collectively, the first three changes reduce the number of TLB shootdown IPIs by 1/3 for a kernel compile. |
