In the meantime, I notice that Alan has put an incompatible version of the mtrr patch into 6-ac1. What are the differences between these two implementations of mtrrs for AMD processors, and is a merged version in the works? The -ac1 version doesn't seem to work at all on my machine, /proc/mtrr exists but doesn't change when I "echo" to it.
By the way, I've missed the discussions, AMD seems to offer just two MTRRs. But I'd like to set up at least 3 distinct regions (main memory, 2d framebuffer, and voodoo2 memory). I suppose I just give up and do only main memory and 2d framebuffer. Should I do something complicated like changing the second mtrr to the voodoo2 card when a mesa app starts up, and restoring it when it ends?
