Re: Linux Input Layer messing with my IR remote ..

With a previous kernel, I did not have this problem, and [I] don't
know where to look.

What's the output of "uname -a"? What's the output of "lsmod"?

I have an infrared remote. I can properly load the lirc_gpio module,
and link [the] lirc daemon to say, mplayer commands. The problem is
that the Linux Input Layer takes the IR signal as well, and acts as if
I was pressing some key on a multimedia keyboard [as well as sending
an lircd event].

Here is the content of /proc/bus/input/devices
[snip]
I: Bus=0001 Vendor=1461 Product=0771 Version=0001
N: Name="bttv IR (card=123)"
P: Phys=pci-0000:01:08.0/ir0
S: Sysfs=/class/input/input2
H: Handlers=kbd

This is a little strange. I certainly don't have anything like that for
my IR remote, but mine is an ATi USB remote, not a remote that's plugged
into a bttv card. There's some stuff about IR in
drivers/media/video/bttv* , but I'm not sure how it all fits in with the
input layer.

This is part of my modules.conf
bttv pll=1,1 card=1,123 tuner=3,4 bttv_gpio=0,0 dvb-bt8xx
lirc_gpio gpio_mask=0xf00f0 gpio_lock_mask=0x20 gpio_xor_mask=0xf00f0
soft_gap=0 sample_rate=10 debug=1 card=1

What could I possibly do to get rid of the Linux Input Layer (for IR,
that is ...), and let lircd alone ?

Very good question. Since it's being seen as a keyboard, the quick
hackish fix of chmodding the thing's device node won't work. I'd guess
the solution would lie in the parameters you feed to bttv, but I don't
know where to start there--possibly because I'm using 2.6.15.6 here, and
you're probably using something newer. Ah well, answer the questions
posed above, and you might get some better help.
