I am starting a project using a PMC Sierra RM9222 processor. Could anyone
that has used the RM9200 family please recommend a distribution and tool-chain?
What has been your experience with Linux on this processor? What secrets and
limitations have you found along the way? I am new to MIPS and SMP.
Has anyone tried to use the RM9000 processor in SMP mode ? Is code
available for it ?
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?
