Avoid re-walking the page table from the root for every PTE examined. Tidy up some of pmap_remove()'s helper functions. pmap_enter: Set PV_TABLE_REF whenever the physical page being mapped is managed, not just when it is writeable. Only call pmap_update_page() when the old mapping was valid. If there was no prior valid mapping, then pmap_update_page() serves no useful purpose. However, it will interrupt every processor that has the pmap active. pmap_enter_quick_locked: Always set PTE_RO. pmap_emulate_modified: Don't set PV_TABLE_REF. Eliminate a nonsensical comment. |
