Any existing means for Inter Processor Communcation?

We are using the Zynq-7000 SoC with one Cortex-A9 core running Linux and the other core FreeRTOS. We need a method for sending data and signalling between two applications running on separate cores and hence OS'.

Do you know of any existing method for doing so?

 

I have not been able to find anything, so I'm planning to make a mechanism my self using the On-Chip Memory (OCM) / shared memory.

Well, actually not. It seems to be over kill to drag in virtio and remoteproc for something as simple as exchanging data through shared memory. I'm back to making my own solution.
