Is it necessary to exit a kernel in order to transfer data to host?

Hello everyone! I recently got my hands on an OpenCL board and so far it's been really nice to work with it. Question: I want to send regular updates up to the host and down to the kernel...

From the Altera Programming Guide:

--- Quote Start ---

Consult the board_spec.xml file in your Custom Platform to identify the input and output features available on your FPGA board.

--- Quote End ---

In the case of my Nallatech board, there is no support for channels except for the network interfaces. However, in the Altera documentation there is a clear reference to a channel io named "pcie", so the support is there. There just need to be a support from a vendor for this feature.

Thanks for the help Smith!
