this question reminds me on the student project of Martin Stein several years ago. Martin's goal was to emulate I/O devices backed by an on-target VHDL simulation. Both the driver and the simulated I/O device would be hosted on the same machine. Each time the driver accesses a memory-mapped I/O register, the simulated device would need to handle that access. Martin solved this problem on the base-hw kernel on ARM. Please refer to his thesis for more information. http://genode-labs.com/publications/mstein-device_emulation-2011.pdf Cheers Norman -- Dr.-Ing.
