KWorld ATSC 115 all static
After upgrading to Fedora 10 I am no longer able to tune analog or dvb channels using my KWorld ATSC 115. When I try to view a channel with tvtime all I can see is static and when I try to scandvb I keep getting tuning failed even though I know that there are channels being broadcast on the channels scanned. I have tried to find tips on the wiki of how to resolve my static problem but I could not find any. I'm not sure where to look for clues as to why it isn't working.
I have a 1-to-4 splitter with 2 outputs going to the inputs of the KWorld ATSC and another going to a TV so I know there is signal on the cable.
Any help would be really appreciated.
Thanks,
-josh

Hello everyone,
In addition to being a general broadcast message, I have cc'ed in a number of folks.
This (broken analog TV on, at the very minimum, the KWorld 110 and 115 cards) is a known problem that has persisted for a long time. Far too
long now. I last wrote about it here:
http://marc.info/?l=linux-video&m=122809741331944&w=2. No response was generated from that. So I will try again and outline what I believe is the relevant history:
- Mauro, you introduced a regression for these boards in changeset:
7753:67faa17a5bcb (http://linuxtv.org/hg/v4l-dvb/rev/67faa17a5bcb).
Since that commit, analog TV has been broken for these cards.
- Michael commented about this here:
http://marc.info/?l=linux-video&m=121243712021921&w=2
- Mauro responded here:
http://marc.info/?l=linux-video&m=121243995927725&w=2
- Several users have brought this up since then (both here on the m/l's and on internet forums) .
- Michael spun a stopgap solution for this (found here :http://linuxtv.org/~mkrufky/fix-broken-atsc110-analog.patch
<http://linuxtv.org/%7Emkrufky/fix-broken-atsc110-analog.patch> ). It still applies cleanly. Unfortunately, it is not a bonafide solution
because: (a) upon each reboot of the system, the user is required to first "modprobe tuner -r" and then "modprobe tuner" before the analog tuning will initialize and function properly. (b) In addition, Michael's patch may affect/break other devices, so it can not be committed to the master repo.
- Hans, I know you have done a lot of clean ups in regards to i2c, but do not know whether any of your work would have touched upon or have had any impact here. Nonetheless, I'd appreciate your input on the matter too if you are able to comment.
I am hoping that this can be resolved to everyone's satisfaction. In my opinion, this should become a priority item, as this regression's life has spanned over 4 kernels.
[For the sake of full disclosure, I am personally affected by the issue, but I note that I use Mike's patch each and everyday (thank you Mike!), and so, other then the minor inconvenience of having to do a modprobe dance with the tuner module, I am not impacted too much. Other users, however, are left in the dark. And, as I explained in my last message, those AVS users that I addressed this issue with seemed entirely hesitant about using the patch (maybe I scared them with a greivious warning ??). Anyway, as evidenced by Josh (OP for this message) and David (see his recent messages; e.g.
http://marc.info/?l=linux-video&m=123066362106086&w=2), end users continue to encounter this problem. I am only surprised that we haven't heard more about this issue. As I noted earlier on, I believe that its impact is greater then just upon the KWorld 11x cards.]

Josh,
The analog issue was obviously addressed in my last message.
Now, in regards to the DVB handling -- there have been a number of recent Fedora 10 related problems being reported on the lists, and you may happen to fall within that category. I'd suggest having a look at your dmesg output to see if there is any error being reported. Saving that -- search the lists in regard to the recent rash of Fedora problems. And finally, try switching the RF input on which you attempt to obtain a digital signal.

This issue doesn't have an easy fix. The big problem is that some devices like Kworld ATSC 115 needs to send some i2c commands before accessing the tuner. However, depending on the load order, the tuner command can happen before the right time. This trouble is not exclusive with saa7134. We have similar issues with cx88 (for example, Kworld ATSC 120 suffers similar troubles).
As you noticed, applying Michael patch will likely break other drivers.
The proper fix is a major saa7134 redesign, by using the newer i2c methods.
The new i2c interfaces allow you to register the i2c bus first, then register each driver when you want to, and not relying on a code that automatically registers all i2c video drivers found at a random order.
So, with the new i2c approach, we can warrant that we'll first open the i2c gate before binding the tuner and/or the demodulator.
Any other approach with the current way will break some other cards or cause troubles on some situations, like having the driver compiled monolithically with the kernel or if you have two boards on the machine.
The redesign of saa7134 requires lots of work. It requires to a full understanding of Hans Verkuil approach used on ivtv. The ivtv driver is different enough from the other drivers to allow an easy conversion. Also, his approach changed recently with the introduction of the v4l2 subdevices. Even the conversion of the cx18 driver (very close to ivtv) to the newer approach doesn't seem to be that easy, as noticed recently by Andy.
IMO, the better would be if Hans could dedicate some time to convert one of the drivers that have the more usual approach (saa7134, em28xx, cx88, bttv) to the new approach. Then the same patch could be easily converted to the other drivers.
Hans,
Could you help us with this?
Cheers,
Mauro

Yes, I can. I'll do saa7134 since I have an empress card anyway. It should be quite easy (the cx18 complication is not an issue here).

yes, Hans is a very fine guy.
But don't hope for too much for DVB/ATSC related stuff soon.
We know about the problems caused by switching antenna inputs from a digital demod, it was a famous hack from Chris on cx88xx and Mike did good work to port it to saa713x, but unfortunately there was some ongoing loss on the other side of the planet then later.
I doubt that Hans is already aware of it at this stage, but since these days bugs are fixed from guys without even having hardware, and this is good progress, likely they will add new devices the same way too soon. I seem to be far behind currently, all caused by the HDTV hype ;)

Just found your email a few hours back after a PC and internet free day, but so far all seems to be fine and no new issues are visible. DVB-T and DVB-S are OK too.
Just for the record, we still have the issue on FMD1216ME MK3 hybrid tuners that the tda9887 is not loaded on boot. This still needs user intervention.
Thanks!

No, trying on HDTV apps and also Nvidia vdpau consumed some time and I don't have neither a 2.6.28 nor a 2.6.29-rc1 yet.
In that way I might be ranting about myself not at least to have the new bugs :)

Consulting on irc, both Eric and myself can confirm that DVB is working fine for the device (I can only test cable currently, but Eric successfully checked both QAM and 8-VSB). I'm using recent Hg and Eric is using stock FC10 supplied drivers. So, I'm not sure why Josh was having problems.
for me the same and I can't test on these.
The Pinnacle 310i seems to have the LNA support broken, can't test.
Hermann,
The DVB part shouldn't be affected by the patch. It changes the way that tuners are attached at the analog part. So, the tests should be on tea5767 radio and on analog tuner reception.
Also, his patch just changes the way tuner is binding. Manual adjustments on saa7134 cards structs (like adding TDA9887_PRESENT flag) will be needed to fix some issues like what you've reported (driver not loading automatically tda9887 driver).
Cheers,
Mauro

It won't fix the antenna input selection controlled from the digital demod, as told before.

OK, I couldn't help myself and went ahead and tested it. It seems fine, so please test my tree:
http://www.linuxtv.org/hg/~hverkuil/v4l-dvb-saa7134
Let me know if it works.
Hi Hans,
It didn't work. No analog reception on either RF input. (as Mauro noted, DVB is unaffected; it still works).
dmesg output looks right:
tuner-simple 1-0061: creating new instance
tuner-simple 1-0061: type set to 68 (Philips TUV1236D ATSC/NTSC dual in)
I tried backing out of the modules and then reloading them, but no change. (including after fresh build or after rebooting)

Can you give the full dmesg output? Also, is your board suppossed to have a tda9887 as well?
Regards,
Hans

Hans' changes are not enough to fix the ATSC115 issue.
I believe that if you can confirm that the same problem exists, but the previous workaround continues to work even after Hans' changes, then I believe that confirms that Hans' changes Do the Right Thing (tm).
ATSC115 is broken not because the tuner type assignment has been removed from attach_inform.
This is actually a huge problem across all analog drivers now, since we are no longer able to remove the "tuner" module and modprobe it again -- the second modprobe will not allow for an attach, as there will be no way for the module to be recognized without having the glue code needed inside attach_inform...
...unless somebody has a suggestion?
Anyway, if the previous workaround works after Hans' changes, then I think his changes should be merged -- even though it doesnt fix ATSC115, it is indeed a step into the right direction.
If the ATSC115 hack-fix patch doesn't apply anymore, please let me know -- I'll respin it.
Regards,
Mike Krufky
