information of what to copy to where comes from the object dictionary.
But it is possible to extract this information from the objdict and pass
it via generic structures (e.g. something like IO vectors) to the PDO
module in kernel. The information flow of the configuration data is
one-way only, from userspace to kernel. This is what I plan to implement
in openPOWERLINK, because the copy information can also be passed to a
special hardware like a DMA controller.
Ok so your hardware in fact really is oriented around an mmap type
interface ?
