ad 7a34cb95f0 Replace the global vm_page hash with a per vm_object rbtree. 
Proposed on tech-kern@.
 2008-06-04 15:06:04 +00:00
ad cbbf514e2c - vm_page: put listq, pageq into a union alongside a LIST_ENTRY, so we can 
use both types of list.

- Make page coloring and idle zero state per-CPU.

- Maintain per-CPU page freelists. When freeing, put pages onto the local
  CPU's lists and the global lists. When allocating, prefer to take pages
  from the local CPU. If none are available take from the global list as
  done now. Proposed on tech-kern@.
 2008-06-04 12:45:28 +00:00
ad 6dd8a2b97b uvm_pageidlezero: 
- Use high and low water marks to try and reduce power consumption.
- Do trylock on uvm_fpageqlock, and bail if we can't get it.
- Only run on one CPU at a time.
