of cache-index incompatible virtual mappings for a physical page may be required for hardware without secondary (level 2) cache to detect and correct virtual coherency problems. I'm not sure this is really needed anymore, since pmap_prefer() took care of of the cache-index incompatible mappings that I have seen. Count the times a page is cache inhibited in enter_stats if DEBUG. Wait for memory instead of panic() on failure to allocate a page for the segtab or segmap [from OpenBSD arc port]. Also check for malloc() failure on allocation of a new pv entry and panic(). Increment resident_count when adding a new page to a pmap [also from OpenBSD]. Process resident size is now valid. |
