bt878 drivers kernel 2.6.15.3

lord-fu · 02-18-2006, 04:43 PM

Hello all and thanks in advance for any help.
I have the ATI TV Wonder card. Worked great on the default kernel. However I have now gone through a few different kernel versions and decided to settle down with the 2.6.15.3 version. I am having a hard time finding where I can select the option for my card in the kernel config, before(if I remember correctly) video4linux gave me the bt878 module option however now I see it will give the videodev module and I cannot find the bt878 module.

lspci does show I need that module:
03:0a.0 Multimedia video controller: Brooktree Corporation Bt878 Video Capture (rev 11)
03:0a.1 Multimedia controller: Brooktree Corporation Bt878 Audio Capture (rev 11)

I have tried to load the module:
root@ATRAEU>05:30:16
$modprobe bttv
FATAL: Module bttv not found.

modules.conf shows no driver being loaded which I kinda guessed would not be there anyways:
# --- BEGIN: Generated by ALSACONF, do not edit. ---
# --- ALSACONF verion 1.0.8 ---
alias char-major-116 snd
alias char-major-14 soundcore
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss
alias snd-card-0 snd-intel8x0
alias sound-slot-0 snd-intel8x0
# --- END: Generated by ALSACONF, do not edit. ---

Furthermore this link http://linux.bytesex.org/v4l2/build.html does say that the everything is included in the kernel as before, I have downloaded the bttv drivers as a just in case. Maybe I am just going blind and cannot find the correct module options, but could someone kindly help me?

On a side note I do all my kernel work outside /usr/src/kernelversion, I do everything in ~/build/kernels/kernelversion. Afterwards the kernel source stays there and I just move bzImage to /boot/vmlinuz. If I need to compile the bttv drivers I just point to the above source correct? If I need to post more output I gladly will, I am sure it is something small I am missing. I use tvtime for my viewing pleasure if that matters.

edit: I do have video4linux compiled in as a module but videodev does not show up in lsmod:
root@ATRAEU>05:41:03
$lsmod

Having nothing better to do, I decided to grep the kernel config for 2.6.15.3 in slackware and I found this that may be of help to you:

Code:

DVB/ATSC Support for bt878 based TV cards (VIDEO_BT848_DVB)

This adds support for DVB/ATSC cards based on the BT878 chip.

If you run make xconfig you will find all the goodies in the section under:

Device Drivers -> Multimedia Devices -> Video for Linux -> Video for Linux -> BT848 video for Linux ->

DVB/ATSC Support fot BT878 based TV Cards.

From PV's kernel config:

Code:

#
# Video Adapters
#
CONFIG_VIDEO_BT848=m
CONFIG_VIDEO_BT848_DVB=y

Hello and thank you for your response.
Under the kernel source in my /build/kernels/linux-2.6.15.3/ I checked the config and there is no option for this module.

Code:

#
# Video For Linux
#

#
# Video Adapters
#
# CONFIG_VIDEO_PMS is not set
# CONFIG_VIDEO_BWQCAM is not set
# CONFIG_VIDEO_CQCAM is not set
# CONFIG_VIDEO_CPIA is not set
# CONFIG_VIDEO_STRADIS is not set
# CONFIG_VIDEO_MXB is not set
# CONFIG_VIDEO_DPC is not set
# CONFIG_VIDEO_HEXIUM_ORION is not set
# CONFIG_VIDEO_HEXIUM_GEMINI is not set

Code:

root@ATRAEU>10:03:11
$cat .config | grep BT878
root@ATRAEU>10:03:33
$

I will just build the bttv drives then?
Thanks in advance.

I get the impression from your initial post that you have built your own kernel an not used the kernel from /testing. I'm running Pat's 2.6.15.3 with no changes and I can modprobe bt878 without error:

Code:

root@peggyo:/home/steve-st# modprobe bt878
root@peggyo:/home/steve-st#

root@peggyo:/home/steve-st# lsmod | grep bt878
bt878                   7992  0
bttv                  153168  1 bt878
root@peggyo:/home/steve-st#

I would try installing his kernel from testing - be sure to make an initrd if the root filesystem is a module.

If you want, I can post the config file.

edit: I should mention I'm running -current and this is the latest kernel version in the -current tree for /testing. You may not be.

Correct Franklin I have built my own kernel. I grabbed it from kernel.org. I will get PVs' kernel now. I should have in the first place.
Thanks again for the quick response.
No I am not runnning current only a few upgradepkgs here and there...is this an issue? I do however have fun just changing kernels and running into issues like this and fixing them. Is this bad?
Thanks again.

Edit: All worked out with the kernel from testing thanks you.

Nope. I just didn't know your comfort zone and did not want you to go looking for a kernel that would not be there if you were not running -current.

[can ya tell I'm bored ...

No, but be aware that the farther -current gets from stable, the more likely packages from -current will start complaining that libfoo.so.bla.bla is missing if you don't upgrade everything. Take a look at how many packages were rebuilt against new libs over the past 10 days. Of course, it's an easy fix - unless you run swaret and think swaret broke your system.

Slackware's package management system is between the ears.

Good luck.

My comfort zone is between my comfy office chair and this here keyboard :] Thanks alot for the help.

Just a quick update just in case anyone searches this thread out in the future. In order to actually have a bt878 option I had to enable under
Device Drivers > I2C Support > I2C device interface
and then I was able to goto
Multimedia Devices > Video For Linux > Video Adapters > BT848 Video For Linux > DVB/ATSC Support for BT878 cards

Sorry to repost just hope someone finds it useful.
