P4080 multicore extension

[sumanthmushiger]

Hello,

I would give you a background of my work first.

BACKGROUND:

I have completely working RTOS on Core0 of P4080. Its booted via SD card using U-Boot.

Now my next job is:

Port Seven Different kernels on the remaining 7 cores -  AMP system.

1. Please let me know how do I proceed?  -- STEP BY STEP procedure.
2. I am told to use this running CORE0 to ignite other cores.
3. If there are any documents or any license free codes which I can use for reference ?
4. I read the document ePAPR, but it wasn't conclusive for me.

Since, I have to execute this project in 15 days, your help will be greatly appreciated.

Thank you.

You can use topaz software to partition P4080 into eight different partitions with single core each.

All the OS kernels you want to run in each partition must be ePAPR compliant.

Linux is an example of ePAPR compliant OS.

The RTOS also needs to run under the context of first partition on core0.

From there, the RTOS can start the other partitions (on other cores) one by one using hypercalls provided by topaz.

Can you please give me the link to topaz, all that I can see about topaz is something related to photography.
