Because lircd is the only userspace application that uses the LIRC kernel interface, we never had any problems changing the interface when needed. I can't say there's much legacy stuff inside. I'm quite happy with the interface. The other thing is that I can't really move the decoder from userspace to kernel because there are way too many userspace drivers that do require a userspace decoder. LIRC also is running on FreeBSD, MacOS and even Cygwin. So letting the userspace drivers take advantage of a potential Linux in- kernel decoder is not an option for me either. I'm having my 'LIRC maintainer' hat on mostly during this discussion and I do understand that from Linux kernel perspective things look different. > Take advantage of this window to make a > design that is fully integrated with Linux - put IR on equal footing > with the keyboard and mouse as it should be. That's a question that I have not answered for myself concludingly. Is a remote control really on exactly the same level as a keyboard or mouse?
