答复: ????: coherent_ht_mainboard()

[YhLu]

The CPU0->AMD8131->AMD8111 is right.

The link CPU0 to CPU1:  in CPU0 side(link0) is 16x600 and CPU1 side(link0)
is 16x800

All others is 8x200.

The coherent should be all 16x1000

I will try your patch and dig it out.

Regards

YH.

Which link is this? CPU0->AMD8111?
I seemed to have no problems on quartet with 1.1.5, which is 4 way as
well.
Have you been able to track the problem down to a certain function/flaw?

Does AMD really support 1Ghz Operation between CPUs?  If so I am
fine with this.  Otherwise I have not seen any significant benchmarking
differences so I would mask out the 1Ghz capability...
