We have dvb-apps/util/av7110_loadkeys, but it makes no sense to replicate this for each card. I remember there was some discussion about IR input and configurable keymaps on lkml a long time ago, but no one came forward and implemented something. Gerd Knorr wrote drivers/media/common/ir-common.c, which might be reusable/extendable for DVB. > Will lirc ever be inside the stock kernel? Is lirc an option for such > things? There is a difference between traditional LIRC drivers, which output raw samples from an IR receiver to be interpreted by userspace software (which is very flexible), and the IR drivers we have for DVB, which output decoded rc5 (or similar) codes. IMHO it makes sense to feed rc5 events to the linux-input system via a keymap. We should either have some generic module to allow user-settable keymaps, or it could be implemented in userspace as a daemon which reads from /dev/input/eventX (using EVIOCGRAB), does the key mapping and feeds back to /dev/input/uevent. I don't know if there's already some software which does this, or if the lirc folks are interested in this. Johannes
