The huge benefit of a userspace driver is that it > can load configuration files. And bear in mind the fact that only handful of lirc drivers are in kernel. Many drivers are pure userspace and live in the lirc daemon itself. These drivers ether will have to be reimplemented in kernel (huge job) Or we will have a lot of duplication, because same remote can be used with kernel or userspace drivers. Look at daemons subdirectory of lircd to get the idea of how many such drivers exist. Btw, for _some_ user space drivers its not possible to re implement them in kernel, like driver that reads input from a sound card, which I can say is nice very cheap way to have a receiver. I want to repeat the correct way of doing things: 1 - all drivers that do all processing in hardware, will use input system. 2 - all drivers that decode protocol will use ether lirc, to keep configuration in one place. 3 - all drivers that send pulse/space will use lirc. lirc will process the data, convert it to input events and feed them back to kernel. Please note, and note again. We aren't taking about two interfaces for userspace! Everybody agree that userspace programs will only recieve input events. The point is that we give an exception for one program that yes is just a userspace driver to recieve the raw data, process it, and feed it back. Also same program (lircd) could receive data from other sources, and convert that to input events. Whats wrong with that? If we add in-kernel decoding, we still will end up with two different decoding, one in kernel and one in lirc. Could we finally end this discussion and move forward?
