(x86 processors with PAT and IA64 can set write-combining through page flags. x86 processors with MTRRs but not PAT would need a more elaborate implementation for write-combining.)
What is PAT? I desperately need to figure out how to turn on write combining on a per-page level. I thought I had to use MTRRs, but now you're saying I can use this "PAT" thing instead.
