Running RM9000 in SMP mode

Running RM9000 in SMP mode

[Thomas Petazzoni]

Hello,

Has anyone tried to use the RM9000 processor in SMP mode ? Is code
available for it ?

Thanks,

Thomas

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

Hi,

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.

Thanks,
Bryan Althouse

Bryan,

The following are available at ftp.pmc-sierra.com

cross tools: gcc-3.3+ with E9000 core compiler optimizations
 
userland: demo userland, monta-vista based, native compiler does not have E9000 optimizations

kernel snapshots: Yosemite/RM92xx SMP capable for 2.4.21, 2.4.26, 2.6.10

doc: pmon and linux readme and board docs.  www.pmon2000.com for online pmon2000 command reference.

Of course linux-mips.org for kernel sources and status, cvs-web, other userland pointers, all the port bits eventually get there.  The E9000 optimizations were committed to gcc.org, available in gcc-3.4.

Datasheets and docs requiring NDA contact support@pmc-sierra.com or your sales/FAE contact.

Brad,

Just out of curiosity, does the processor being used below: Rm9222 have 
the five state MOESI protocol support?

Thanks
