how to create 8 partitions using hypervisor in P4080DS

[peterzheng]

Hi,

I have successfully installed the hypervisor on P4080DS following the documentation. But it only shows 2 partitions, one with 7 CPU, one with 1 CPU. The project I am doing now requires me to create 8 partitions on P4080ds.

I can't find a documentation on how to partition the system.  I only found this by Yiping.

https://community.freescale.com/docs/DOC-102249

But there are a few points now very clear.

(1) where do I find the hv.dts file? I cannot find it in the SDK

(2) after I modify this hv.dts file, do I need to rebuild the image?

(3) how do I update this change, do I need to rebuild the image and flash it onto the board?

Thank you for your help.

Regards,

Peter Zheng Zhipeng

Hi,

For the questions:

(1) where do I find the hv.dts file? I cannot find it in the SDK

You may find it in Where is the hv.dts file in Freescale SDK 1.6 for P4080DS

(2) after I modify this hv.dts file, do I need to rebuild the image?

Yes, I think so. As this is only the textual representation of device trees.

(3) how do I update this change, do I need to rebuild the image and flash it onto the board?

Yes, I thinks this depends on your deployment method.

Please someone else correct me if you don't think so.

Have a great day,
Lunmin

Hi Lunmin,

(1) I am unable to find the hv.dts file at the location you mentioned. Can I just use the dts file you provided in the attachment?

(2) After modification, should I use DTC tool to compile, can you show me the steps?

(3) I use TFTP to transfer deploy the image. Is it enough if I just deploy the DTB file? Or do I need to re-deploy the UImage as well?

Thanks,

Peter

Hi Lunmin,

Thank you very much for your answer. However, if I would like to partition the L3 cache of P4080DS in CodeWarrior. Do you know how to do that?

For example, using some cache management instruction.
