[ATrpms-users] lirc not working with kernel 2.6.22 and Leadtek Winfast 2000XP

[Jeffrey J. Kosowsky]

YIPPEE! I finally got lirc working with my LeadTek Winfast2000XP
Deluxe controller on kernel 2.6.22

Key steps were as follows:

1. Patch and recompile the bttv module
   Note: the patch referenced several other places on the net uses
   ir->mask_keycode = 0x0f8 which cause some keys on my (bundled)
   remote not to work and others to show up as duplicate
   keys. Instead, use: ir->mask_keycode = 0x8f8.

   The full patch is:

-----------------------------------------------------
NOTE: to recompile just the bttv kernel module, do the following:
	  Download the kernel source rpm and install it (rpm -Uvh)
	  Then run: rpmbuild -bp --target $(arch) kernel-2.6.spec
	  Patch bttv-input.c (in /usr/src/redhat/BUILD/kernel-2.6.22/linux-2.6.22.i686/drivers/media/video/bt8xx)
	  Then go to /usr/src/redhat/BUILD/kernel-2.6.22/linux-2.6.22.i686
	  and recompile just the bttv module using:
		  make  M=drivers/media/video/bt8xx

2. Then you need to generate a new lircd.conf file since the keycodes
   differ from the old gpio generated one that is included with the
   standard lirc tarball.

   Run: irrecord -H dev/input -d name="bttv IR (card=34)" lircd
   and follow the instructions.

   Note, the lircd.conf that I generated is as follows:

# Please make this file available to others
# by sending it to <lirc at bartelmus.de>
#
# this config file was automatically generated
# using lirc-0.8.3-CVS(dev/input) on Tue Nov  6 17:04:54 2007

# brand:		LeadTek
# model no. of remote control: Y0400046 (bundled with Winfast 2000XP Deluxe)
# devices being controlled by this remote: LeadTek Winfast 2000XP Deluxe

# brand:             Leadtek
# model:             Y0400052 (bundeled with Winfast PVR2000 TV-card)
#
# Note: Only CH_UP, CH_DOWN, VOL_UP and VOL_DOWN will repeat. This
# seems to be a limitation of the remote control.

Finally, test that it all works by restarting the lircd service and
running irw and then pressing the keys on your remote.

Note: I set /etc/sysconfig/lircd to:
	# Options to lircd
	LIRCD_OPTIONS='-H dev/input --device name="bttv IR (card=34)"'
