How to upgrade BTTV properly ?
 

Hello,

I run a Knoppix (Kernel version 2.4.20) and the embedded BTTV driver is 0.7.96

As my Pinnacle PCTV didn't work, I decided to upgrade my kernel and my BTTV drivers.

Here is what I did :

=> download kernel source (2.4.21)
=> apply patch found on bytesex.org/v4l/build.html ("kernel patch" link)

=> compile && install the new kernel (not necessary for bttv I believe but it was quite funny)

It worked perfectly.
Then, I decided to really upgrade bttv by downloading the 0.9.x version

I opened the tarball, untar it in my /home/~/files directory, ran make && make install : it worked perfectly

BUT

at the loading of the system, the old bttv is still loaded (I saw it in kern.log)

I think that the latest bttv only creates a few .o that are in a particular directory... including bttv.o... but the kernel still loads the old one in /kernel/media....

Do you know a way to force the kernel to load the latest bttv at startup ?

Thanks in advance... already spent a lot of hours without success :confused:

I think (not 100% sure) that you can tell it to use the newer bttv by passing 'v4l2=1' in the opitions when you load the bttv module.

I didn't work unfortunately

here is what I put in modules.conf :

#### Begin BTTV Config ####
alias char-major-81 bttv

options bttv card=39 pll=1 v4l2=1
(as you told me)

options tuner type=33 debug=1
options msp3400 once=1 simple=1
post-install bttv modprobe tuner; modprobe videodev
#### End BTTV Config ####

Maybe that is the wrong place ?

try unloading the module 'modprobe -r bttv'
then reload it 'modprobe bttv card=39 pll=1 v4l2=1' and see what dmesg spits out at ya

Here is the result :

Warning: ignoring v4l2=1, no such parameter in this module
Module bttv loaded, with warnings
Using /lib/modules/2.4.21/kernel/drivers/media/video/tuner.o
insmod: a module named tuner already exists
/lib/modules/2.4.21/kernel/drivers/media/video/bttv.o: post-install bttv failed

The modules.conf seems to be the key... I tried to replace the 2 lines I mentioned in the previous post with something I found on the forum :

#tv config start
alias char-major-81 bttv
options bttv card=39 pll=1
options tuner type=33 debug=1
options msp3400 once=1 simple=1
post-install bttv modprobe tuner; modprobe videodev
#tv config end

And now (without rebooting) the result of what you suggested is :

Warning: ignoring v4l2=1, no such parameter in this module
Module bttv loaded, with warnings

... but this still is the old version

Moreover, in bttv path, there is a script called update which unloads the old version of the driver and loads the new one. Maybe I could adapt it to modules.conf ?

#!/bin/sh
source modules.sh
set -e

case "`hostname --short`" in
eskarina)
btopt="card=66"
;;
esac

xrmmod bttv
xrmmod btcx-risc
xrmmod video-buf

v4l2basic

xinsmod video-buf debug=0
xinsmod btcx-risc debug=0
xinsmod bttv bttv_debug=0 vbi_debug=0 irq_debug=0 \
fdsr=0 sloppy=1 chroma_agc=1 vbibufs=4 $btopt

I think that v4l2=1 can be passed to xinsmod... which is defined in another script (modules.sh) !!!

Frankly, it's pretty hard to configure...

Yep. it is the old version.

Let's see if a new one got built. try 'locate bttv.o' and then do an 'ls -la /path/to/bttv.o' for each version you find.

Locate and ls -la gave me back

(this is the latest version i'm quite sure)


******USELESS I SUPPOSE*********

But I still don't guess what to do :confused:

I have the same problem now did you find a way to load now version of bttv ?
