[patch] bttv: support WinFast TV2000XP IR receiver
Last modified: 2009-01-09 01:26:17 EST
Description of problem:
bttv module needs patching to work with IR receiver bundled with Leadtek WinFast
TV 2000 XP tuners.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Run any recent kernel
IR receiver does not work until patched
IR receiver works "out of the box"
The hardware is fairly old and common. It used to work just fine until the bttv
code "cleanup" sometime last year. From there on, it requires the stock kernel
to be patched before it will work. See:
Created attachment 303851 [details]
Patch for drivers/media/video/bt8xx/bttv-input.c
bttv0: detected: Leadtek WinFast TV 2000 [card=34], PCI subsystem ID is 107d:660
bttv0: using: Leadtek WinFast 2000/ WinFast 2000 XP [card=34,autodetected]
input: bttv IR (card=34) as /class/input/input6
05:01.0 Multimedia video controller: Brooktree Corporation Bt878 Video Capture (
Subsystem: LeadTek Research Inc. WinFast TV 2000
Flags: bus master, medium devsel, latency 32, IRQ 19
Memory at ea200000 (32-bit, prefetchable) [size=4K]
Capabilities: <access denied>
Kernel driver in use: bttv
Kernel modules: bttv
That patch is in the official 2.6.25 kernel now.
Thanks for the pointer. But from what I can see, the patch is only partial. For
the transmitter bundled with my board,
ir->mask_keycode = 0x8f8;
ir->mask_keycode = 0x1f8; (line 249)
as in the official 2.6.25 kernel.
This message is a reminder that Fedora 8 is nearing its end of life.
Approximately 30 (thirty) days from now Fedora will stop maintaining
and issuing updates for Fedora 8. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '8'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 8's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 8 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora please change the 'version' of this
bug to the applicable version. If you are unable to change the version,
please add a comment here and someone will do it for you.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
The process we are following is described here:
Fedora 8 changed to end-of-life (EOL) status on 2009-01-07. Fedora 8 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
