We want to be able to ``clone'' devices remotely.
Something like this would be nice:
Device 0:
netcat port | ./clone-device
Device 1:
read-device /dev/input/inputX | netcat addr port
--
Filtering, injecting or rewriting of input would also be very nice. Possibly
with a configuration file / small scripting language.
Filtering could be done either with another program, or integrated into
clone-device; since filtering makes no sense if you do not also create a new
device. OTOH, if you're doing much more than filtering, like injection or
rewriting, then it makes more sense to give a different name, maybe
input-modify?
Problems:
- We cannot just pass around struct input_event ; endianness may become an issue
- We cannot perform ioctls to read all the events/buttons exposed by a device
over the network. I suggest that by design these are just passed over the
network once. (As they cannot change at runtime anyway)
- We need a proper configuration file or scripting language. Although I guess
the C macros work fine for now. We can even make a nice Makefile that generates
seperate binaries per config:
make my_config # uses config/my_config.h to generate map-my_config
