That's all quite sensible, but what's this "uc minus" thing that keeps showing up in charts and comments?

Getting a handle on caching Posted May 15, 2008 21:47 UTC (Thu) by arjan (subscriber, #36785) [Link] "UC minus" is basically "Uncached unless something else says otherwise". So if PAT says "UC minus" and the MTRR says "Write Combining" the result is "Write combining". However if PAT had said "strong UC" and the MTRR had said "Write combining", the result would have been "Uncached"
Getting a handle on caching Posted May 15, 2008 21:55 UTC (Thu) by arjan (subscriber, #36785) [Link] (just to clarify; if PAT says "UC minus" and the MTRR says "Cached" then the outcome is still "uncached"; so it's really "Uncached unless the MTRR says write combining")
