Kworld 115-No Analog Channels

Kworld 115-No Analog Channels

[Jason Pontious]

After getting upgraded to the latest v4l-dvb repository I am no longer able
to get any analog channels from my Kworld 115. (I finally broke down and
installed 2.6.25 kernel in Ubuntu).

Before I was getting analog channels via the top rf input.  Now I get no
channels regardless if i set atv_input tuner_simple module setting.  Digital
channels are not affected just analog in this.  I get no errors from dmesg.

Any Ideas?

Thanks!

Which drivers are you really using, 2.6.25 or latest v4l-dvb from
Mercurial?

I ran into a similar (probably the same) problem last week.  My search
of the list archives revealed a known tuner detection regression in
2.6.25.  It's supposed to be fixed in Mercurial but I didn't test it
because it was simpler to just go back to 2.6.24.x.  I don't know why
the fix hasn't made it into 2.6.25.x yet.

I am using the current v4l-dvb from mercurial as the latest there now has a
feature to allow you to select the rf input for analog channels which I
would like to have.  I upgraded to 2.6.25 in Ubuntu because of the way
Ubuntu is currenlty handling their kernel modules doesn't allow for an easy
compile of the drivers from mercurial.

I was not aware the input selection method had been changed again.
Thanks.  Now, I'll know to expect a conflict with my own hack when
this makes it into the mainline kernel.

Note to Michael Krufky.  I could be [probably am] missing something,
but to me it looks like there is no way to force the use of input 0
when QAM is used.

        case TUNER_PHILIPS_FCV1236D:
        {
                unsigned int new_rf;

                if (dtv_input[priv->nr])
                        new_rf = dtv_input[priv->nr];
                else
                        switch (params->u.vsb.modulation) {
                        case QAM_64:
                        case QAM_256:
                                new_rf = 1;
                                break;
                        case VSB_8:
                        default:
                                new_rf = 0;
                                break;
                        }
                simple_set_rf_input(fe, &buf[2], &buf[3], new_rf);
                break;
        }

If dtv_input is set to 0, it will be misinterpreted as autoselect and
then the use of QAM_64 or QAM_256 will make the code use input 1!

David,

"1" is tuner 1
"2" is tuner 2  (actually, "not one" is tuner "not one")
"0" is autoselect

Ah, OK.  Thanks for clarifying.

Which fix?  What problem does it fix?  More details, please :-)

P.S. ...  I respond quicker if you cc me.  ;-)  (I should have added
that to my last email, not this one)

When I ran into the problem last week, I went searching and ran across
this thread:

https://www.redhat.com/mailman/private/video4linux-list/2008-April/msg00221.html

I don't know if any of the posted patches or changes that eventually
went into mercurial fixed my problem or not.  Downgrading to 2.6.24.7
did fix the problem for me.  Since the above thread looked like the
same problem as mine, I figured I'd stick with 2.6.24.x until it got
fixed in 2.6.25.x or 2.6.26 comes out.

Here are the details concerning my problem.  When running 2.6.25.4,
analog capture on a Kworld ATSC 115 doesn't work with tvtime reporting
no signal.  Here is a snippet of my boot log with 2.6.25.4:

Manually specifying the tuner type when loading the saa7134 module
makes no difference.

Notice the additional log entries regarding the tuner detection.

FWIW, I have another system with 2 KWorld ATSC 115s.  That system has
always had issues with tuner detection no what kernel I use.
Depending on which PCI slots I place the cards in, I either get 0 or 1
tuners detected, but never 2.  I posted about that problem several
months ago, but never got a response from anyone.

Under 2.6.25, can you confirm whether or not the "tuner" module is
actually loaded?  If it is loaded, can you do:

modprobe -r tuner
modprobe -r tuner-simple
modprobe tuner-simple debug=1
modprobe tuner debug=1

...then test again and show the dmesg logs.

Mike

it is the first posting from Ian Pickworth there, followed by an reply
by me, since Ian helped on several cx88 norm setting issues and also
with the tda9887 radio support, you might not remember anymore, but to
leave him without reply is beyond my scope.

The bug was confirmed then by Gert, who did the initial empress encoder
support.

However, Mauro fixed the eeprom detection then within all that immense
traffic and work during the last merge window open.

Remaining serious issues are, since 2.6.25 the users can't select the
PAL/SECAM subnorms anymore after the ioctl2 conversion, which is an
extremely bad idea on saa713x, and further it is more improved on 2.6.26
now, that they are not even to set the tuner type anymore, without to
change it in the source, which is another extremely bad idea, as I
posted several times.

I don't blame anyone, Hartmut and me were also too much focused on the
outstanding DVB-S stuff that time and did not care much about analog,
but the driver is in serious troubles now and I'm a little bit grumpy,
or at least not in the mood to explain again and again were we are ...

Cheers,
Hermann

Hermann,

Please don't top-post.

David Engel's problem is unrelated to the issue that you describe -- I
will address his issue in a separate email.

The issue that you are describing is due to the change in load order
during initialization.  Mauro made this change very late in the
2.6.25-rc stages, against my recommendation.

I am staying away from this issue, since I advised against that
change.  So, I defer to Mauro (cc added).

Mauro, are you aware that this is still an issue?

...some helpful hints:

this will not work unless we do the following, in this order:

This won't work, since tveeprom and tuner can be compiled in kernel or they may
already be loaded (for example, if you have two boards on your machine with
different bridges, the second bridge setup will run after the load of those
modules). 

We can postpone the call of SET_TYPE, or allow that a second SET_TYPE to be
accepted, but we can't make any assumption about the module load order.

If, previously, the driver were assuming a that I2C drivers were compiled
as module, and a certain load order, the driver were already broken.

The problem is not related to when a driver is loaded, but when I2C binding
happens.

Since we are using the old probe methods on most boards, after I2C is
initialized by the bridge, any existing i2c driver will try to bind on it.
Also, there's no control on the order that each i2c driver will be attached to
the i2c bus.

The proper fix is to migrate all drivers to the way that ivtv and cx18 are
probing i2c devices. This way, we can control when I2C bind for tveeprom and
for tuner will happen. So, we can do what you are meaning: bind first tveeprom,
then do the proper card setup and bind the tuner.

Cheers,
Mauro

No, I didn't.

I only used/abused exactly this to point at the outstanding issues
again, or do you seriously assume that I don't know that the Kworld ATSC
stuff is not within eeprom tuner detection issues on saa7134?

Yes, this was tested by me and confirmed and posted.

Unluckily I don't have enough free PCI slots currently anymore to trace
the two analog only cards I have with tuner eeprom detection 24/7.

Mike, Mauro, thanks for confirming that it is not unnoticed and
forgotten.

David,

The fact that reloading tuner.ko confirms my suspicion --

In the case of the ATSC110 / ATSC115, we can't attach the tuner client
module until after the NXT2004 has been initialized with its i2c gate
left in open state.

If you unload all v4l/dvb drivers and modprobe saa7134, I believe this
will work properly, since the demod has already been initialized once,
with the gate left open by default.

So, that's a workaround to your problem.  When I find some spare time,
I'll investigate into what changed in 2.6.25 that led to this issue.
This is *not* the same issue that Hermann described in his mail.

This jives with what I saw in further testing.  After it worked once,
it would continue to work across all sorts of module reloads.  I
thought there was one time it didn't continue to work, though, but I
could never reproduce it.

Thanks.  It would be very nice to get this fixed.  FWIW, I just tried
unloading and reloading tuner/tuner-simple on my system with 2 ATSC
115s and 2 PVR x50s.  All tuners were detected for the first time I
can remember.  The PVR x50 tuners were always detected but no more
than one of the ATSC 115 tuners was ever detected before.

I've been following this discussion closely and will give you my input from
what I have seen.  Here is my output from a 2.6.24-rc4 kernel with the
v4l-dvb drivers included in that kernel.

My output from lsmod | grep tuner is :

I dont have analog channels before or after this.  I should have some set of
analog channels on either input.  Before with the ubuntu 2.6.24 I would
receive analog from the top input.  With 2.6.26-rc4 I can't seem to get
analog no matter what.  I'm not sure how my problem applies to the rest of
this conversation or if its completely different.

Let me know if you would like me to test anything else.

Thanks!

module load order matters.  to explain how and why is beyond the scope of this conversation.  To make things easy, use "make unload" inside the v4l-dvb tree to unload all the media drivers.  (do NOT ever use make load)

The order that you loaded above will not propogate the debug=1 module option to tuner-simple, since you already loaded 'tuner' and saa7134 is already running -- the combination of saa7134 and tuner will automatically load tuner-simple without any regard to your command line module options.

try this:

make unload
modprobe tuner-simple debug=1
modprobe tuner debug=1
modprobe saa7134
modprobe saa7134-dvb

If the top input doesn't work, then try the bottom one.  Use the module options to change them if you like.

If things still dont work, then try the following:

make unload
modprobe saa7134-dvb
modprobe -r tuner
modprobe tuner

...that should do it.  Try both inputs.

Well after trying everything I could think of I could never get analog
channels to work with the drivers that came with 2.6.26-rc4.  I finally gave
up and went back to the 2.6.24 ubuntu kernel and modified tuner-simple.c
file and recompiled the module.  Hopefully you guys understand the problem
and have a fix in mind.  I wish I had time to debug all of this.  I had
analog channels on 2.6.24 it was just using the wrong input for my setup.
With 2.6.26 I got no analog channels (with the exact same options used in
2.6.24 setup).  Which is strange since I should have some analog channels
either way since I have both inputs connected.  With 2.6.24 I got the
"wrong" analog channels.  With 2.6.26 I got NO analog channels period.  I am
running amd64 but I doubt this is causing any issues.

Well just thought I would update you guys on where I ended up.  Thanks again
for all the help you provided!  I learned more about the v4l kernel modules
than I ever imagined during this.

Set tuner-simple debug=1 -- this will cause the driver to tell you
which input is being used for what purpose at driver startup.  This
should help you to debug the issue on your end.
