SMP on MV64460

SMP on MV64460

Hello group,

    I am currently working on a board which has MV64460 linked between two 7447a processors.  I wanted to know if someone has been able to get the Linux 2.6 kernel working with any MV64xxx bridge.

Thanks,
Lance

I think there are people out there that have made this work.  However, I
haven't b/c I do not have access to any SMP hardware that has all of the
necessary h/w errata implemented.

Perhaps others that have hardware will speak up?

I happen to have such a board, DB64460-BP, on
hand. 
But even 2.4 kernel has some problems with
MV64460
PCI part. I wonder whether there is a 2.4 version

support that with PCI device like VGA card. 

Thanks,

Sam

There are a few of examples of SMP using the MV64460 from Curtiss =
Wright,
but I don't know of a 7447A SMP (you really need a backside external =
cache
to take advantage of SMP).  The CWCEC boards support 2.4 or 2.6.

The above linkage is broken to me. With google, 
I got some other info as well. I will report
back if some improvement.

Thanks,
