I'm happy to see that the discussion is getting along. But I'm still a bit hesitant about the in-kernel decoding. Maybe it's just because I'm not familiar at all with input layer toolset. 1. For sure in-kernel decoding will require some assistance from userspace to load the mapping from IR codes to keys. So, if there needs to be a tool in userspace that does some kind of autodetection, why not have a tool that does some autodetection and autoconfigures lircd for the current device. Lots of code duplication in kernel saved. What's the actual benefit of in-kernel decoding? 2. What would be the format of the key map? lircd.conf files already exist for a lot of remote controls. Will we have a second incompatible format to map the keys in-kernel? Where are the tools that create the key maps for new remotes? Maybe someone can shed some light on this. Christoph
