Hello, I have Debian Sid 2.6.7 and Nova-t with ir port. I managed to get key events on /dev/input/event? but not the correct ones for my rc (some keys were wrong, some were not found). So I searched the archives and found: http://www.linuxtv.org/mailinglists/linux-dvb/2003/11-2003/msg00473.html and http://www.linuxtv.org/mailinglists/linux-dvb/2004/05-2004/msg00540.html So I looked at video/ir-kbd-gpio.c and common/ir-common.[c|h]. Also on evdev.c. I decided to use ioctl directly in budget-ci.c as this is the simplest for me. The patch attached fills the input_dev members keycodemax, keycodesize and keycode to the static key_map. So nothing else must be changed (except the meaning of input_dev.repeat_key) and the default key mapping can stay. I also filled in the member phys and id like in ir-kbd-gpio.c (this was mentioned in some reply of the threads above). When coding I swapped the lines input_register_device(&budget_ci->input_dev); and for (i=0; i<sizeof(key_map)/sizeof(*key_map); i++) if (key_map[i]) set_bit(key_map[i], budget_ci->input_dev.keybit); The result is that "kbd" does not install an eventhandler on this input device. I find this useful to me, but may be someoneelse not - I didn't find anything to prevent "kbd" capture the rc events. With this patch one can change the key map table with the ioctl functions. I use Gerd Knorrs input-kbd from http://dl.bytesex.org/cvs-snapshots/input-20040421-115547.tar.gz A sample file for my rc (the same as the one mentioned in the later thread above) is appended. I added the line install budget-ci /sbin/modprobe --ignore-install budget-ci;\ /usr/local/bin/input-kbd -f /etc/nova-t.rc 4 to my /etc/modprobe.d/dvb so the right mapping is added after loading the dvb moduls. I decided to not use ir-common as the support in budget-ci was quite simple and otherwise the code to debounce has to be added to ir-common. I think the same can be applied very simple to av7110_ir.c. To the point that this method does not work for 32 bit rc codes: The ioctl functions would support 32 bit rc codes. The problem is the data structure in input_dev and its handling in evdev.c. The member keycode is an array of key events (KEY_*) indexed by scan codes. This way it is used by ir-kbd-gpio and the keyboard drivers and handled by evdev.c. To support 32bit rc codes (without 4GB tables) I propose a new imput_dev member keyscancode. When this is null everything works as before. If it is not null, it is an int array with the same length like keycode and contains the [scan|rc]code to the corresponding event code in keycode. This is simple and none of the old drivers must be changed. There is one "bug" in input-kbd: it does not delete old entries when loading a new mapping. The diff is to the kernel 2.6.7 source code.
