| H A D | sr.h | diff 126478 Tue Mar 02 04:49:21 MST 2004 grehan Increase kernel VA from 256Mb to 512Mb by shifting the segment used for user copyinout down to 12, and keeping segments 13/14 for kernel VA. It would be nice to have more available, but segments lower than this are reserved for either memory or 1:1 mapped device i/o, and seg 15 is OpenFirmware ROM. Also, the effort to keep OpenFirmware available for callbacks limits the use of VA-mapped segments. Fortunately UMA_MD_SMALL_ALLOC takes away a lot of VM pressure. Obtained from: NetBSD |
