Hello Thomas
The Rm9000x2 revision 1.1 and 1.0 does not have support for the five
state MOESI protocol and can only support SMP if appropriate hacks are
applied to the memory management code. The revision 1.2 of the chip does
support MOESI protocol and SMP. I am sure PMC can provide you with the
necessary sources. Which board are you using?
Thanks
