I suspect that Dmitry did the patch against the Debian package, based on a 2007 version of it, as it seems that Debian is using an older version of the package. Anyway, I've ported his patch to be applied over your -git tree, and tested on it, with vanilla 2.6.37. That's the incorrect output result of the old version, with an existing NEC extended map: $ sudo /tmp/input/input-kbd 2 /dev/input/event2 bustype : BUS_I2C vendor : 0x0 product : 0x0 version : 0 name : "i2c IR (i2c IR (EM2820 Winfast " phys : "i2c-0/0-0030/ir0" bits ev : EV_SYN EV_KEY EV_MSC EV_REP bits: KEY_1 bits: KEY_2 bits: KEY_3 bits: KEY_4 ... And that's the output after applying the patch: $ sudo ./input-kbd 2 /dev/input/event2 bustype : BUS_I2C vendor : 0x0 product : 0x0 version : 0 name : "i2c IR (i2c IR (EM2820 Winfast " phys : "i2c-0/0-0030/ir0" bits ev : EV_SYN EV_KEY EV_MSC EV_REP map: 31 keys, size: 31/64 0x866b00 = 393 # KEY_VIDEO 0x866b01 = 2 # KEY_1 0x866b02 = 11 # KEY_0 0x866b03 = 386 # KEY_TUNER - [PATCH] input-kbd - switch to using EVIOCGKEYCODE2 when available From: Dmitry Torokhov <dmitry.torokhov@xxxxxxxxx> [mchehab@xxxxxxxxxx: Ported it to the -git version] Signed-off-by: Dmitry Torokhov <dmitry.torokhov@xxxxxxxxx> Signed-off-by: Mauro Carvalho Chehab <mchehab@xxxxxxxxxx> diff --git a/input-kbd.c b/input-kbd.c index c432d0d..aaf23b9 100644 --- a/input-kbd.c +++ b/input-kbd.c @@ -9,9 +9,22 @@ #include "input.h" +struct input_keymap_entry_v2 { +#define KEYMAP_BY_INDEX (1 << 0) + uint8_t flags;
