Hi
I'm in the process of converting applications from VxWorks to Linux.

I have a multitude of VME boards with write/read registers (no
interrupts). On VxWorks I usually have built subRecords to access the
registers on the boards.

Now we use Concurrent single board cpus in VME (running linux) where the
use of mapping registers is restricted due to the large address space of
the cpus. So I would like to map the individual boards in an orderly
fashion via some register-board-base-addr call and then use for instance
asyn int32 support.

I have looked in the example int32Driver.c but can't see where the real
I/O is done?
Does anyone have some real example? Or is this sort of overkill?
Many thanks, Burkhard
