Inter Processor Communication

Hi,

To answer that question, we don't have that support as of now. None of the releases we have made have IPC between 2 linux kernels.

I don't think we will support that anytime soon.

What we will have over the next few months is virtio which can be used for communication between 2 linux kernels.

I'll ask a collegue of mine to provide more info.

Thanks,

Sandeep

Thank you Sandeep for your answer.

I'll be thankful if you can provide more info.

Thanks,

In the next Linux C6x release we will provide an Ethernet type of communication between two Linux kernels running on two different cores (http://linuxc6x.org/wiki/index.php/Roadmap#Late_Q1_April.2FMay_2011:).

This inter-core Linux communication is based on the Linux Virtio framework and more specifically using the virtio-net driver. Notice that this communication does not use the hardware EMAC, it is purely software and only based on the C6474 inter-core interrupt mechanism.

It will provide a second network interface (eth1) on top of which you can use TCP/IP with socket interface, RPC or other inter-core communication framework like TIPC.

Of course this IPC is message based due to the Ethernet semantic.
