Description of problem:
The module tda1004x (DVB-T demodulator chip) is missing from the FC2
Test 1 kernel. This module is required to get DVB-T running with the
Hauppauge WinTV Nova-T card.

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1. search for tda1004x kernel module
2.
3.
    

Additional info:

Comment 1 Bernd Bartmann 2004-02-16 17:31:43 UTC
The module does not appear in "make menuconfig" when using the FC2
Test1 supplied .config file due to "CONFIG_STANDALONE=y"

Comment 2 Arjan van de Ven 2004-02-16 17:34:12 UTC
"CONFIG_STANDALONE=y" means we don't want build-time firmware.
Which is correct, we can't generally download all firmware for some
driver and just distribute it; quite often that's not even allowed.

Comment 3 Bernd Bartmann 2004-02-16 17:40:27 UTC
Arjan, the existense of the firmware file is not a build time
requirement. In fact you can also supply a different firmware filename
at module load time.

Comment 4 Arjan van de Ven 2004-02-16 17:42:51 UTC
then the Kconfig for the file is borken.....

Comment 5 Bernd Bartmann 2004-02-16 17:55:30 UTC
Just sent a mail to the DVB mailing list about this problem.

Comment 6 Bernd Bartmann 2004-02-16 20:38:20 UTC
The DVD guys seem to have fixed this in their CVS after my problem
report, but now I have another problem. In the meantime I rebuild the
FC2 Test1 kernel to include the tda1004x module (using the supplied
.config). While trying to load the tda1004x module I'm getting this
error message:
                                                                     
                            
FATAL: Error inserting tda1004x
(/lib/modules/2.6.1-1.65bb/kernel/drivers/media/dvb/frontends/tda1004x.ko):
Unknown symbol in module, or unknown parameter (see dmesg)
                                                                     
                            
In /var/log/messages I get:
tda1004x: Unknown symbol sys_close

Any ideas how to fix this one?


Comment 7 Arjan van de Ven 2004-02-16 20:45:08 UTC
they have very evil code there; it's not allowed to read files from
kernel space like that, they should use request_firmware interface

Comment 8 Bernd Bartmann 2004-02-17 23:07:26 UTC
Now it finally works for me. Watching DVB-T television the whole
evening :-)

All I had to do was to re-add EXPORT_SYMBOL(sys_close) to fs/open.c
which was removed by your linux-2.6.0-compile.patch.

Comment 9 Neil Aspinall 2004-02-20 09:35:50 UTC
I also got this working by changing all calls to sys_close() into
calls to close() in drivers/media/dvb/frontends/tda1004x.c.

Is there a reason for Fedora not exporting sys_close() from fs/open.c?

Comment 10 Arjan van de Ven 2004-02-20 09:38:32 UTC
any user of it is broken. It cannot be used correctly.
tda1004x.c is rather broken. Really.
Even when not using request_firmware() and co, opening a file needs to
be done differently.


Comment 11 Alan Cox 2004-05-03 19:59:13 UTC
Being resolved upstream, will be picked up over time once firmware
handling is in the base kernel [and possibly when someone reminds us
to turn it on 8)]. 



Comment 12 Thomas Vander Stichele 2004-08-25 14:56:50 UTC
Is there much value of deprecating/removing stuff from the FC kernel
that's not (yet) done upstream ? I thought the new point of FC kernels
was to stick as close to upstream as possible ?

Looks like a fix for this is finally on the way.....
