Huh? Why would you want to rmmod and modprobe tuner? Anyway, drivers that
use v4l2_subdev (like my converted saa7134) will increase the tuner module
usecount, preventing it from being rmmod'ed.

There was a load order dependency in the saa7134 driver.  Some users 
have to remove tuner and modprobe it again in order to make analog tv 
work.  Yes, that's a bug.

The bug got worse when Mauro made changes to attach_inform -- I believe 
this was for the sake of some xceive tuners... I don't recall the 
details now.

Anyway, long story short... there are many different bugs all 
manifesting themselves at once here.  Load order dependency -- I don't 
think we ever understood why that issue exists.  The fix for the load 
order dependency no longer works, as attach_inform no longer cares if a 
new tuner appears on the bus.

So, my ATSC115 hack-patch restored the attach_inform functionality for 
the sake of ATSC110/115 users.  I am not pushing for its merge -- this 
*will* break the boards that Mauro was working on when he changed 
attach_inform.

As I don't really understand what he was going for when he made those 
changes, I don't know how to fix this problem without creating new bugs 
on Mauro's cards.  I put out that patch in hopes that somebody else 
would put the pieces together and make a better fix that would work for 
everybody.  That hasn't happened yet :-(

It has nothing to do with the load order. It is related to i2c binding. With
the current approach (before Hans patch), the i2c core will try to bind the
tuner after having 2 conditions satisfied:
	1) I2C bus were registered;
	2) tuner code is available.

So, if you load tuner before saa7134 (or have it compiled in-kernel), the code
will try to probe tuners at the moment you register i2c bus. Otherwise, it will
try to bind only when request_module is handled.

Some devices with DVB has an internal i2c gate. For a subset of these, the i2c
gate is inside the tuner. So, you need to bind the tuner device before probing
for the frontends. On the other set of devices, the gate is inside the demod.
So, you need to turn the i2c gate before running the i2c address seek for tuner.

This generated lots of issues in the past, like machines with two boards
doesn't work anymore. With two boards, and a tuner module, the first board
probes tuner after opening the demod gateway. However, the second board will
try to probe tuner before opening the i2c gateway. So, tuner is not found.

-

After having Hans patches working, we need to implement the following workflow
inside the driver:

1) register the i2c bus and load tuner (the order shouldn't be relevant
anymore, since the attachment is not related anymore with i2c bus register and/or
with tuner load);
2) call the i2c open gate control, if it needs to open the demod i2c gate in
order to access the tuner;
3) tuner type is determined via eeprom and/or board entry;
3) tuner i2c address is scanned and tuner is bound with the proper type;
4) the i2c open gate control is called, if needed in order to access the demod;
5) demod is bound.

Hacks won't be needed anymore.

All we need is to fix the board entries, properly identifying what is needed to
access tuner and/or demod, and double check what devices need tda9887.

I wonder if a better way to fix these problems is to use virtual I2C busses
for the gate?  When a device has some kind of i2c gate, it creates a new
I2C adapter for the devices behind the gate.  The code for this virtual i2c
adapter can just open the gate, pass of the request to the main i2c
adapter, then close the gate.  Creating a new i2c adapter should trigger
the i2c drivers that scan to do so and find new devices behind the gate.

It seems like this would solve the scan order problem, since the bus the
tuner/demod/whatever is on won't exist until the gate it is behind can be
properly controlled.

There are a number of additional benefits too.  There are many devices that
can be behind many different kinds of gates.  So we have all these gate
control functions that must be called manually from all over the place.
This adds bloat and developers are always forgetting to call them, which
doesn't cause any problem they notice because their card doesn't have a
gate.

With manual gate control, we must remember to close the gate when done with
the device.  But this isn't always done and the gate is left open.  These
gates are there for a reason, to shield RF devices from noise created by
the I2C bus, and so leaving them opens impairs RF performance.

And when the gate is only controlled by the driver in the kernel, it is
hard to manually debug/test i2c devices from userspace with i2c-dev.

What I see on the md7134 card=12 (about ten different devices) is not
related to missing has tda9887 something, especially not on the FMD216ME
MK3 hybrid. The tda9887 becomes only visible there at all with that
special buffer sent from tuner-core. (0x05 IIRC)

To have the tda9887 always in the kernel and never as module might fix
it. Untested ;)

Hi Hans,

Yes, indeed, the device does contain the tda9887.

err, I'm afraid I might be reading to much into your statement Michael
--- if you meant to question whether, after building Hans' changes, a
"modprobe tuner -r" and "modprobe tuner " worked, then the answer is no,
such did not work. (no results in dmesg are observed either, much like
what was discussed later; specifically:

If you had meant taking Hans' source and applying your "hack" patch to
them, building and then proceeding with the modprobe steps, the answer
is that I haven't tried yet. Will test -- might not be tonight though,
as I have some other things that need attending too.

Given this statement, then perhaps it was a case of the latter. As
mentioned, I will rebuild and test.

Hans, given the discussion that is developed, I don't think the dmesg
output is necessary at this point (if you really insist though I will
provide :P ).

P.S. I think Trent's idea sounds interesting/warrants some consideration.

For now, we should finish the Hans approach, since it also helps to stop using
the legacy i2c methods. After having all drivers using it, we can do some
cleanup at the drivers.

However, I like the idea of providing a better support for those buses that
have an i2c switch inside (I don't like to call it "virtual" - it is a real i2c
bus, where part of the bus is controlled by a switch).

I'm not sure if we should implement it inside v4l core, or at i2c-core. 

Maybe the latter could be more appropriate, since maybe some other devices could have
similar issues, like the embedded processor/controllers, where you have an i2c
bus there connected to several different devices, like those used on cellular
phones. 

I bet that some embedded devices uses the same i2c bus for more than
one subsystem (like having a radio and/or a webcam and some temperature/battery
sensors). In this case, a virtual i2c support could be interesting.

Maybe Jean could give us some suggestions about the better approach for such cases.

Mauro

The "hack-fix" patch applies cleanly against Hans' sources. However, the
test results are negative -- the previous workaround ("modprobe tuner -r
and "modprobe tuner") fails to produce the desired result. In fact, as
similar to the results reported in the previous message, performing such
action produces no result in dmesg.

Such workarounds won't work anymore. If his patch is correct, the behaviour
should be deterministic. Could you please enable the debug messages and probe
cx88 with i2c_scan=1? Please also post the previous dmesg.

If you try to run 'modprobe -r tuner' when the saa7134 module build from 
my sources is loaded, then that should not work since saa7134 increases 
the use-count of the tuner module preventing it from being unloaded.

If you can do this, then that suggests that you are perhaps not using my 
modified driver at all.

BTW, I've asked Mauro to pull from my tree 
(www.linuxtv.org/hg/~hverkuil/v4l-dvb) which contains the converted 
saa7134 and saa6752hs drivers. It's definitely something that needs to 
be done regardless.

Hans, Mauro has pulled them in already.

For my report for the old issue with the tda9987 not loaded for the
md7134 card=12 with eeprom tuner detection and all the types with
FMD1216ME MK3 hybrid subsumed there beside the older ones with analog
only tuners (CTX917/918/925triple/946mpeg/921cardbus), the users must
just unload the saa7134 and tuner modules and then load tda9887 and
tuner before the saa7134 for now.

That's not possible -- tda9887 is now a sub-module of tuner-core.  
tda9887, when modprobed alone, will not attach to any actual device 
without also having tuner.ko loaded in memory.  tda9887 is a separate 
module, but its interface is currently only accessed via tuner-core 
(tuner.ko)

Mike, please look.

You can see that the previously not loaded tda9887 is present and
initialized now.

Changing hardware without notice is something manufactures still do, which
makes probing even for modern hardware still useful in some cases.

But the old hardware that was always probed uses the same i2c clients as
the new hardware that has gates and muxes.

The I2C layer doesn't have a concept for an i2c bus segment, so an
i2c_adapter is the next closest thing.  One could create an entirely new
struct i2c_bus for that, but how would it be different than the currenct
i2c_adapter?  It seems like just another layer of complexity.

I can think of a few more ways to do.  The main adapter could get
registered with no I2C_CLASS_* (or with something like I2C_CLASS_MUX) so
clients that scan won't scan it.  Then create virtual adapters for gate
closed and gate open.  Scan gate closed first and then excluded any
addresses found from the gate open adapter.

The scanning order problem.  The adapter is scanned before the gate can be
controlled.  Works better with i2c-dev too.  Suppose I have a new card or a
new revision and want to scan for devices behind the gate and see if I can
figure out what they are?

I think some multi-tuner cards have real muxes.  But if the system created
for muxes can be applied to gates as well, why not use it instead of
creating something else for gates?

First adapter created with the class set to 0 or I2C_CLASS_MUX, so nothing
scans it (except a mux driver that scans).  Mux is added with
i2c_new_device() and creats new busses/adapters for each segment.  These
have the "real" class for the device and so get scanned.

I think the gates are primarily meant to shield the device from noise
relating to i2c bus traffic for other devices.  So it shouldn't be a
problem to leave the gate open as long as it's closed when a message that
doesn't need to go behind the gate is sent.

But I would expect limited probing then (using
i2c_new_probed_device()), not wide probing using the .detect() method.

This isn't necessarily an issue: your I2C chip driver can implement
a .detect() method for old hardware, where class is set to
I2C_CLASS_TV_ANALOG, while more recent hardware set no class and
instantiate the I2C devices explicitly. The new i2c model allows both
approaches to cohabit nicely.

I agree with you, using i2c_adapter for bus segments is the plan, as
far as multiplexers are concerned. My point was whether it was worth
considering a chip behind a gate as a bus segment or not.

Yeah, that could work in some cases... At the cost of 3 i2c_adapter
instances. And it seems specifically tailored for hardware that need
scanning. I mean, if you do _not_ scan when gate is closed, then you
don't know what addresses must be removed from the gate-opened adapter,
so you can't allow for probing on that adapter.

But this doesn't seem to work in the general case: you may not be able
to actually scan for chips when gate is closed.  Some chips may not
respond to probing (either because they never do, or because they are
themselves behind another gate or multiplexer.) For complex topologies,
I am skeptical that your approach will be practical. It might even be
pretty confusing due to the fact that the apparent topology will be
quite different from the physical one.

(If we go that route then it does make sense to start speaking of
virtual adapters.)

Anyway, there's nothing missing from i2c-core right now to implement
this, is there?

Well, if you have a new card, you presumably don't know that it has a
gate to start with. If you have enough information about the gate, then
I expect you to also have enough information about what is behind it.

One possible requirement this discussion is bringing up, is the ability
to instantiate an i2c_adapter without any probing class set, then do
some initialization (e.g. accessing the gate chip, and close the gate)
and only then add probing classes (or have a separate function to ask
for re-probing of a given adapter.) This would fulfill your needs,
wouldn't it? Then we can stick to the physical topology.

If we had support for muxes already, they I'd say yes, let's handle
gates the same. But the problem is that full muxes support is a
non-trivial thing, and we don't have it now, and I have no idea when we
will have it. I _hope_ before the end of the year, but I didn't even
start working on it, and I don't have any hardware to test either.

My main reason for suggesting a simple handling of gates is so that you
can have it quickly. But if you prefer to help me (and others)
implement full support for muxes instead, you're very welcome :)

Mux drivers should not scan. I mean, I've never see a mux chip that can
be detected. You should _know_ what mux you have on your bus.

Huh?  Of course I'm using your modified driver.  As a recap:
*  I tried Hans' modified sources and the test result was negative.  I
also attempted (in a similar fashion as to the steps required when using
Mike's "hack/workaround") unloading all the modules and then modprobing
them .... as Mike later explained, the modifications Hans had made are
not enough to correct the issue
* Mike then asked whether:
(a) his "hack/workaround" still applied cleanly against Hans' source,
and stated that, if that was not the case, then he would re-spin the
"hack" patch ... I confirmed that Mike's "hack/workaround" did indeed
apply cleanly against Han's source. 
(b) I was successful in getting the analogue TV working after applying
his "hack/workaround" patch against Hans' source.  However, as I
reported, the results of this test were negative ... as Mauro later
explained, the "hack/workaround" that Mike had spun will no longer work
given the inherent changes introduced in Hans' code

As requested by Mauro, I will provide the dmesg output,  both that from
the base case and then that given when 12c_scan is employed ... but that
will have to occur either later today or sometime during the week ... at
present, I have switched back to an older changeset, as I required
having a functional second TV this weekend

Err, while I agree that the changes are something that need to be done
(I don't think anyone is in disagreement with that consensus), I don't
think that this is a case of "regardless".    In fact, I stand behind
Mike's position:

> Anyway, if the previous workaround works after Hans' changes, then I
> think his changes should be merged  

But as I have demonstrated above, and as Mauro explained, the previous
"hack/workaround" no longer works in the case of with the Hans source
code.  The "if" case fails!  Consequently, the "else" case should be
don't merge.  Why?  Because we have now gone from:
* circa pre-2.6.25, Mauro's changes that  broke the boards analog TV
support, but which could somewhat be corrected by Mike's "hack/workaround"
* to present, where merging Hans' code eliminates the usability of
Mike's "hack/workaround" ... in essence, analog TV function has now been
completely killed with these boards.

Now, if it is a case that a resolution to the problem is imminently
forthcoming, then I don't think that the merge would be much of a
problem.  However, given the breadth of the conversation so far (and I
really do appreciate the depth of Trent's and Jean's
discussion/consideration on the matter), it is entirely unclear to me
that such a resolution will be found in short order  (although, I don't
discount the possibility of it either).

And, although I may have altered some of the original text at some point
in time (and looking at it now, I see that it could stand for some even
more clean up/revision), I turn everyone's attention to the

Hans,

Between the time of my last message and now, your title has made a turn
for the better.  I proclaim that you are no longer "Hans-the-Destroyer",
rather you should be upheld as "Hans-the-Enabler" !!

In other words, it works !!  (across reboots etc etc).

The output of dmesg is interesting (two times tuner simple initiating):

Would you like to see the results of after enabling 12c_scan to see what
is going on, or is this the behaviour you expected?


Some Other Miscellanea:
1) Before this gets merged, can I ask you to also make one small change
to tuner-simple; specifically, swap the contents of lines 301 and 304.  
This will change the driver's default behaviour in regards to the
selection of which RF input to use for digital cable and digital
over-the-air.  Currently, the driver is set to use digital OTA on the
top RF input and digital cable on the lower RF input spigot.  However,
IMO, a more logical/convenient configuration is to have the digital
cable input be handled by the top RF input spigot, as this is the same
one that the analog cable is also drawn from by default. Mike had made
this change, on my request, previously, but it appears that it got
reverted after the tuner re-factoring. 

Note:  users have reported different default configurations in the past
(e.g. http://www.mythtv.org/wiki/Kworld_ATSC_110), but I actually doubt
that there has been any manufacturing difference with the TUV1236D. 
Rather, I suspect that the user experiences being reported are just
reflecting a combination of the different states of how our driver
behaved in the past and differences in driver version that they may have
been using (i.e. that version provided by/within their distro or by our
Hg).  After all, this configuration setting has gone from being handled
by saa7134-dvb.c to dvb-pll.c to tuner-simple.c, with changes in the
behaviour implemented along the way.

2) This is likely related to the discussion about the gate -- after
closing the analog TV app, the audio from the last channel being viewed
can still be heard if one turns up the volume on their system.  This
leakage has always been present.  But given that we are addressing this
issue now, it strikes me that the gate is being kept open on the audio
line after application closing/release occurs.

3) there is an issue about having two of these cards in the same system
--- IIRC, only one card will get /dev/video .... Mauro touched upon this
very briefly in one of the earlier messages; recall:

Mauro wrote:
> This generated lots of issues in the past, like machines with two boards

Now, I can't test for this myself, but I do know of several users on
AVSforums who have two such cards and can test if that issue is now
resolved .... do you suspect that the changes you have implemented to
date will have eliminated this bug too?

Cheers, and many much appreciation.

The Philips TUV1236D NIM does indeed use a tda9887  (I know, because I
was the one who discovered this some four years ago (pats self on
head)).  But the module is not loading.  I can make it load, just as
Hermann demonstrated to Mike in one of the recent messages for this thread.

In regards to the tuner type being set twice, that is precisely my point
-- its peculiar and not symptomatic of normal behaviour.  That is why I

It is a trivial change which I can vouch that works (after successfully
testing your new "KWorld" changeset, I immediately applied this change
and rebuilt ... with, of course, successful results).

I just did some testing in regards to point number 2 ... at first I was
thinking that maybe it was because tda9887 is not loading automatically
that, absent of fine control, the audio leakage was occurring.  But
after loading tda9887 and then removing the module, the leakage
continues.  Naturally, the other suspect is saa7134.  And, as it turns
out, if one modprobe -r saa7134-dvb (which obviously uses sa7134), then
the audio leakage immediately comes to an end, and checking lsmod,
saa7134 is no longer found.  So at least I know the source of the bug
now ... now its just a case of getting it to release properly.  Comments
from anyone on this?

Okay, cool!  As soon as this change gets pulled into the mail line, I'll
prompt those folks on AVS to test.

Yep.

And what of the deeper discussion that evolved (re: Trent and Jean's
ideas)?

IIRC, some hybrid cards have the ability to power down or hold in reset the
analog and/or digital demod when they are not in use.

Since the module load order between tuner and the bridge can't be depended
on, there really should be another way to make sure all i2c devices are out
of reset before scanning for them.

If the demod is controlled by a bridge gpio, then just turn it on _before_
adding the I2C adapter.  Then the chip will be there when the scan happens.
Might need to check how long the demod takes to some out of reset and add a
delay.

If one I2C chip is controlled by another I2C chip on the same bus (e.g.,
analog demod controlled by a gpio on the digital demod), then there is
currently no way to scan for it.  Maybe if the i2c core gave us a "rescan"
function?  Not a bad idea really, other busses have this.

But I think trying to making scanning work with these complex inter-device
dependencies is just perpetuating the mistake of scanning for devices in
the first place.

Much better would be if the tuner driver would let us use i2c_new_device()
or an attach function like the dvb drivers use.  One of the reasons why I
think refactoring the hybrid tuners to use the v4l-style tuner module from
dvb style attachment was a move in the wrong direction.

Unfortunately, I don't have nxt200x datasheet. Things would be clearer with the docs.

The issue doesn't seem to be related to TUV1236D, but, instead with nxt200x.
The i2c command to enable the tuner is sent to nxt200x. If there are any
ATSC110 variant with a different demod (maybe a different version of nxt200x?),
then the users may experience different behaviors.

Please test the enclosed patch. It adds a proper gate_ctrl callback at saa7134
core, and initializes it for ATSC110. 

The gate_ctrl is close to what we currently have on cx88 driver, however with a
simpler implementation. We'll likely need to improve it, moving the i2c gate
control into nxt200x, adding the i2c close commands, and putting the gate_ctrl
initialization into saa7134-dvb.

You should notice that we don't know how to close the gate. So, the code is
still a workaroud.. However, to properly implement it, we need the help
of someone with the datasheets.

This should be needed to do per board. The issue here is that we need to know
the i2c open and close cmds.

Probably, it has something to do with the i2c gate control.

Yes. We need to fix it asap, to avoid regressions. It is time to review also
the other codes that are touching on i2c gates at _init2().

in my case on the md7134 cards it happens only after cold boot.
Analog of course doesn't work then.

To reload the saa7134 with "modprobe" then is also enough to get it
loaded and analog functional, likely what Mike meant.

On warm reboots it is present and functional. Some eeprom readout
corruption mostly on the first card occurs and I must force card=12.

The tda9887 is by default not visible on the FMD1216ME MK3 hybrid.

The init from Hartmut in tuner-core.c in set_tuner_type for analog.

	case TUNER_PHILIPS_FMD1216ME_MK3:
		buffer[0] = 0x0b;
		buffer[1] = 0xdc;
		buffer[2] = 0x9c;
		buffer[3] = 0x60;
		i2c_master_send(c, buffer, 4);
		mdelay(1);
		buffer[2] = 0x86;
		buffer[3] = 0x54;
		i2c_master_send(c, buffer, 4);
		if (!dvb_attach(simple_tuner_attach, &t->fe,
				t->i2c->adapter, t->i2c->addr, t->type))
			goto attach_failed;
		break;

from dmesg.

dmesg |grep "< c2"
saa7133[1]: i2c xfer: < c2 30 90 >
saa7134[3]: i2c xfer: < c2 >
saa7134[3]: i2c xfer: < c2 0b dc 9c 60 >
saa7134[3]: i2c xfer: < c2 0b dc 86 54 >

Exactly here, when the buffers are sent the second time the tda9887
becomes the first time visible on the bus. According to Hartmut the
modification of buffer[3] from 0x60 to 0x54 is that hidden switch,
IIRC.

My other cards with tda8275a, tda8290, tda10046 and/or tda826x and
tda10086 still work and the FMD1216ME init broken is old. 

There is an old issue, maybe not reported yet, that after suspend to RAM
it seems the AGC control for DVB-T is lost, lots of artifacts. After
using analog TV or reload the saa7134 it is fixed.
Just to mention it.

I believe Mauro is correct in regards to the tda9887 in that, within the
Philips TUV1236D NIM, it is behind the Nxt2004's i2c gate.  After
re-reading what Michael mentioned previously:

I believe that even in the case where I modprobe the tda9887 (such as
how Hermann demonstrated) and get the module to load, it is not
effectively attaching to the device.  So, this still begs Han's
question:  "how do you manage to make analog TV work if the tda9887
isn't found? That's rather peculiar."  I don't have an answer for that. 
The tuner-simple module, however, seems to be able to drive/provide that
functionality sufficiently enough.  Perhaps Michael can shed more light
on this.

In any regard, if anyone is interested, you can observe the internal
layout of the NIM from this Anandtech pic (warning, large image) :
http://images.anandtech.com/reviews/video/ATI/hdtvwonder/tuner.jpg   As
would happen to be the case, the labelling on the tda9887 gets washed
out in the photo, however, one can surmise from the shadow that the
insignia is the Philips badge and, with a good monitor, you can actually
make out "TDA" on the top line of print.

Different demod? -- No, I'm pretty sure that the NIM exclusively uses
the Nxt2004. 
Different revision of the Nxt2004? -- I'd say its quite logical to
suspect that there have been a couple of fabrication spins of the demod
... it is, after all, several years old.  However, although possible, I
don't think a different revision explains the case here.  Rather, as
described above, I just think that it's a case of apples to oranges
comparisons; user experiences that reflect different snapshots of time
and driver revisions.

Though, although unlikely, another thought I have on this is the
possibility of a situation akin to a switch for railway tracks ....
especially if the user first employs the card under Windows -- my
thought is perhaps the Windows driver configures a hard routing pathway.

Anyway, there is, coincidently, a similar analogue-less variant of the
NIM, the TU1236.  As one user reports
(http://marc.info/?l=linux-dvb&m=122314219031405&w=2) it can be found on
the "VE" version of the HDTV wonder.  I believe that the TU1236 is also
differentiated from the TUV1236D by its use of the Nxt2003, as opposed
to the Nxt2004 in the later.

Could not verify.  (dmesg output provided below at end).

Mauro, your patch applied cleanly against mainline.  (But not against
Hans' KWorld test repo; though I don't think you meant/intended for it
to be applied against that anyway).
However, analogue TV functionality still is inoperative.   (dmesg output
provided below at end).

Thoughts on merging the changes from Hans' KWorld repo?

Actually, looking at the dmesg output now, it is apparent that you are
correct:

dvb_init() allocating 1 frontend

So, its a case of a bit of redundancy now.

The tda9887 is a simple device with just three registers.  If they are set
to the right value when the driver loads, which wouldn't be unexpected,
then it isn't necessary to actually do anything to the chip.  If you had a
multistandard tuner (and had access to broadcasts in multiple standards!)
then I expect switching standards wouldn't work without the tda9887 driver.
Verifying both TV and radio tuning works is probably the most realistic way
to check.

That command sequence is sent to the PLL, not the nxt2004, so this is
wrong.  There is another command sent to the nxt2004 (which is at address
0x0a) from code in saa7134-cards.c to "enables tuner" as well.

For radio you need a tda9887 and working i2c for what i can know.

Also after a cold boot the tda988x is not in a usable state for any tv
standard yet, it needs to be set by i2c first.

But for NTSC, and only NTSC, one pin can be strapped, IIRC, and then it
works without any i2c programming needed. Guess it is a tda9885 here.

That the analog demod is enabled from the pll in case of the FMD1216ME
MK3 hybrid is what Hartmut told us.

To remeber, the Pinnacle 300i hybrid with mt32xx (3250) disables the
analog demod with tda9887 port2=0 in digital mode. That is why Gerd
re-enables it on exit of DVB.

Looks like that this is the case, as described by Trent, that is
occurring. Herman, is there any difference between the tda9885 and
tda887, as I'm pretty sure this is the tda9887 package outlined on page
52 of the tda9887 datasheet.

Alas, as being exposed to just NTSC broadcasts, not able to test on the
multistandard ;)

As for the FM radio, I know that some have mentioned the possibility for
that with this device, but I don't think anyone ever has succeeded (not
surprising given the i2c situation) and so the assumption was made,
rightly or wrongly, that it is not present. I would be amused if FM
radio support could be realised for the device.

Oh my, this is close to a decade with us and that is why I still make
noise when early developers are dropped from e-mail with all the
different possible solutions.

For the radio, I wonder why nobody ever tested it on windows ;)

On the tda9887, which only supports it, you find also a tda7240, I might
have the chip wrong and thought just to give some hints for what I
remember, but can't look up further into details right now. This one
does in radio mode the stereo separation and provides in TV mode just
MONO on both lines. You don't seem to have it, but tuner PCBs have also
a backside ;)

It reminds me on what i did try to report for DVB-S on the 0x0008 device
on the Medion Quad. All other report it is fine and don't even notice
the tuner loop through enabled.

But I report it is always at 18Volts, whereas the 0xc4 buffer should set
it to 13Volts, which is described as a prerequisite for external voltage
switching, not fulfilled and obviously not easy to reach for what I
tried and the Philips/NXP m$ driver has the same issue ;)

I've seen i2c switches on a few different places:
	on bridge driver gpio's;
	on demod's gpio's;
	on tda9887 gpio's;
	on tuner/PLL gpio's.

In the case of tuner/PLL gpio's, you'll see some i2c switch magic inside tuner-core, like this one:
        case TUNER_PHILIPS_FMD1216ME_MK3:
                buffer[0] = 0x0b;
                buffer[1] = 0xdc;
                buffer[2] = 0x9c;
                buffer[3] = 0x60;
                i2c_master_send(c, buffer, 4);
                mdelay(1);
                buffer[2] = 0x86;
                buffer[3] = 0x54;
                i2c_master_send(c, buffer, 4);

I'm not sure what would be the better way to address all those kind of i2c
switches. Maybe we should add a field at device struct specifying what i2c
device contains the i2c bridge, in order to initialize it first.

The first i2c bus master should be always first.
On PCI this will be the bridge and nothing else.

I hate to say it, but it was a PITA to argue against the "frontend"
stuff, which until today has no realistic concept for that and confuses
a lot on that side.

To see high tones on every smallest intention to do something better
about it, made it the most frustrating stuff I have seen so far.

I may have found a problem (tvtime works perfectly; other analogue apps
like xawtv/motv, kdetv ... are not working properly now -- you can do a
channel scan with them and everything_appears_to work as expected (i.e.
channels are found and are displayed/played correctly during the scan),
BUT as soon as you actually go to use the app, it does not work
(static).  It appears that the issue is related to dga and Xv (as
passing the -nodga -noxv options with xawtv/motv actually works ...
kdetv is hit and miss -- sometimes the v4l1 mode works, other times it
doesn't (likely a pattern there but haven't found it yet), but v4l2
plugin does NOT work at all (static)).  In addition, the nvidia driver
is NOT the source of the error, as the same occurs under the nv driver
as well. 

Will have to do another test to confirm whether this error was
introduced in the KWorld repo.  Consequently:

I've seen this issue happening with nvidia proprietary driver, on an old
machine I had. the open source nv driver were better (e.g. the bug were much
less frequent than with the proprietary one). This kind of trouble is not
related to the kernel driver.

Ok. FYI, I've committed that changeset I've proposed. Could you please confirm
that the driver is working with the v4l-dvb tree.

As far as I can tell, this thread petered out without a resolution.
CityK later posted on avsforum, however, that analog on his card was
after more changes by Hans.  I'm confused.  Is analog on the KWorld
115 supposed to be working again or not?  I saw that some changes by
Hans made it into the main Hg repository, but as of yesterday, analog
still didn't work for me.

Nope, this thread is still alive and well -- I posted to it last Thurs
(?), and Mauro replied, but I haven't had time to follow up with this
since then. Anyway, here's a synopsis of the situation:

- Hans had a first go at the saa7134 (and related modules) in this work
was in his v4l-dvb-saa7134 test repo .... these initial changes,
unfortunately, were NOT sufficient on their own to get analog TV
working. These changes did, however, get pulled into the mainline of v4l-dvb

- Hans' second attempt at this is found in his v4l-dvb-kworld test repo
... testing this code revealed that analog tv did indeed work again with
tvtime ... I also noted that there seems to be a bit of redundancy now
in terms of the tuner being initialized twice

- Mauro created a patch intended to be applied against mainline ... I
tested and analog tv did NOT work

- On Sunday Jan 25th I sent a lengthy message to the list, outlining
some debug results etc. and also informing Mauro that his patch did NOT
work ... I know that, at the very least, Trent and Hermann received that
message, because they quoted from it in further discussion about the i2c
gate (the inherent underlying problem at the heart of the issue).

- A few days later, scanning through the #irc logs, I caught a
discussion, regarding Mauro's patch getting pulled into mainline, and
the discussion seemed to indicate that there was some confusion as to
what I had said worked and what doesn't. This surprised me for I had
been pretty explicit in my Jan 25th mail list message. The other
alternative was perhaps they simply had missed that message...so, in
order to clear the situation up, I went to the mailing list archive to
find a link for my message...only to discover it was NEVER
achieved/recorded....grrrrr. So I'm at a complete loss as to who
actually saw the Jan 25th message and who didn't.

- Further, somewhat concurrently, I discovered that (with Hans' kworld
test repo) analog TV was ONLY working with tvtime ... xawtv/motv and
kdetv were borked (I don't use Myth, so I have no idea what its status
would be ... though, I'd suspect that it works like tvtime). I quickly
traced this problem to be related to dga and Xv. A very similar
situation with these apps existed several years ago when the proprietary
X drivers from nvidia and ati removed dga functionality from their
respective drivers (for some background read:
http://www.nvnews.net/vbulletin/showthread.php?t=68232, and also the
relevant portion of the FAQ from the nvidia readme:
ftp://download.nvidia.com/XFree86/Linux-x86_64/180.27/README/chapter-07.html),
however, the basic nv driver would still function. Nvidia would later
provide a workaround to this issue in their driver.
So, in this modern day occurrence of this similar error/bug, the obvious
first test is to eliminate the proprietary driver from the equation.
However, the test result with the nv driver was the same -- borked
motv/xawtv and kdetv. I reported this, saying that I suspected that a
something may have been introduced somewhere resulting in this issue
with these apps resurfacing. This is why I asked that Hans' kworld repo
NOT be pulled into mainline (if there had been any thought to that --
though I don't think there was, because I now realize that I don't think
many had even seen my prior Jan 25th message !) until further testing
was performed.

- Mauro replied believing that this was unrelated to anything v4l-dvb,
but rather an artefact of the X drivers. I suspected that that was NOT
the case (the nv driver failing in my previous test was my cue). The
next obvious test was to revert back to an older v4l-dvb snapshot that
was patched with Mike Krufky's hack/workaround.

[reverting back should have been an easy task, but unfortunately I
managed to turn it into a frustrating ordeal --- in the case of Hans'
kworld source, the rminstall process did not blow away all the modules;
further, while I had been testing channel scans with xawtv/motv/kdetv, I
also tried with YAST, and unbeknownst to me, it must have saved an
attempt at configing the ir remote --- so that, later, when no v4l-dvb
modules were any longer present on the system, a config script somewhere
must have been calling for the related remote control i2c-blah-blah-blah
modules and the system would freeze, all too coincidently just when the
nvidia x driver was starting up X ... and booting to failsafe and
console mode was not working either (or at least not very well) ... so
my initial belief that the very recent nvidia driver I installed had
mucked up X, and that incorrect belief/assumption led to a masking of
the real underlying problem for a while ... plus the fact that I really
went off on a tangent messing around with xorg.conf and trying out some
of the recent xinput modules etc etc ) .. anyway, as they say, all roads
lead to Rome, and I eventually sorted everything out]

The older snapshot and Mike's patch worked as I expected it to. Removing
that and installing Hans' kworld repo again --> xawtv/motv/kdetv = fail
with Overlay. I can positively state, WITHOUT DOUBT, that there is
something in Hans code that is sourcing this issue. I have not looked at
it closely, nor do I know if I would recognise it when I do, though I
suspect that it would be from initial batch of changes (inserted into
the v4l-dvb-saa7134 repo).

--------------------------------------------------------------------
So the grand conclusion (aka state of the nation):
--------------------------------------------------------------------

- how to provide a proper solution that will resolve the underlying i2c
gate issue remains a point in discussion. In the meantime:

- Hans kworld repo:
Pros: does provide analog tv functionality for, at a minimum, tvtime.
Cons: The changes introduced result in, as testing to date has shown, a
harmless bit of duplication in the way of the tuner being loaded twice.
kdetv/motv/xawtv, at a minimum, do not work in overlay mode.

- Mainline v4l-dvb:
Pros: none ... you will achieve this thread's namesake -- all static.
Cons: since the code from Hans' v4l-dvb-saa7134 repo was merged, Mike's
hack/workaround patch has been rendered ineffective for good. Mauro's
later patch was also pulled into mainline, but it does not change the
situation analog tv (and I do not mean in relation to Mike's patch, I
mean precisely upon its own).

- Mike's hack/workaround patch
Pros: it will apply and work with snapshots of v4l-dvb up to probably ~
Jan 15th or so. All the apps that I tested with work as expected.
Cons: in order to use analog tv, upon each boot, one must do what I
termed being a dance with unloading and reloading the tuner module via
modprobe.

- And finally, as an end note, DVB does, and always has, continue to
work. As I eluded to earlier (somewhere within this growing thread), the
assignment of RF input spigots has changed several times for these cards
throughout the course of their Linux driver(s)'s lifetime. Currently, by
default:
DVB - digital cable is now accessed through the lower input. OTA/ATSC
off the top input. ... this configuration is opposite to that which
users of 2.6.24 era kernels are familiar with.
Analog TV - regardless of whether ota or through cable is also off the
top input.

It's a load order dependency --  There is no way to toggle the i2c gate 
without first bringing up the demod, which requires firmware.  The 
ATSC11(0/5) requires the DVB bring-up to complete before bringing up the 
analog i2c clients.

Tuner is _not_ loaded twice.  The tuner-simple driver is displaying 
itself twice in the dmesg logs, because it is attached twice.  Once for 
analog, again for digital -- this is *by design*.

The old code used dvb-pll for the digital side, and tuner-simple for 
analog.  The common support within those two modules has been merged 
together to remove redundancy and allow us to share state between the 
two instances of the driver for the same part.

As tuner-simple registers each side of the interface, it will display a 
message to the kernel logs indicating what tuner has been attached -- 
this is what you see twice.

On Jan. 18 the copy to the video4linux-list was dropped.
Some mailers by default have a limit there and the number of recipients

However, all on linux-media should have received your postings and they

I had a quick test on the in kernel radeon driver on Fedora 10 and
recent 2.6.27 with xawtv-3.95.

True is, that overlay-preview yields dga is not supported, but with
current v4l-dvb master and Hans' conversions mmap/grabdisplay works with
the old "xawtv -v 1 -nodga -remote -c /dev/video2" something.

Like you, I can't imagine that the earlier Kworld ATSC 110/15
initialization in Hans' kworld repo could be related to it.

I can test on nv drivers as well next, they might have dropped support
for it too and just the x capabilies should be reported. For the second
attach of hybrid tuners in digital mode we maybe should print something
pointing to it.

I'm not sure if we even have the status of all devices potentially
seeing impacts, but reloading modules becomes more difficult, since we
load now saa7134-alsa by default. This will cause that apps like mixers
on runlevel 5 need to be closed before you can unload/reload
saa7134-alsa and saa7134 and then further any tuner modules.

This is fine for all the cards without such problems, but else one must
be aware off. With "options saa7134 alsa=0" the old behaviour is
restored.

Mauro also disabled saa7134-alsa support on saa7130 devices, which
simply do not support it and the deprecated saa7134-oss. Thanks!

I actually knew that, but as a consequence of writing a long reply, late

misreporting the case.

Mike, thanks for the clarification that the behaviour is intended by
design. And looking at the events in conjunction with the above
explanation, it all makes sense:

Yes, I agree -- adding something simple to the existing message here
might help any future cases of head-scratching by those less
knowledgeable of the intricacies.

Yep, as I menitoned: 
http://www.mail-archive.com/linux-media@vger.kernel.org/msg00989.html. 
In regards the hit and miss functionality I mentioned with kdetv, the
pattern was simple:  grabdisplay v4l1 mode would work only after having
just used tvtime.  Similarly, in the v4l2 mode, after having just used
tvtime, one can observe a momentary flicker of video (i.e. lasting only
a few hundredths of a second) from a channel before it reverted to all
static.

Additionally, when the apps fail in overlay mode, and are displaying all
static, you can actually simultaneously open up one of the digital apps
(take your pick; kaffeine, MPlayer...) and successfully watch dvb.

No, no -- Mauro doubts it.  I,  on the other hand, suspect that there
has been something innocuous introduced  within the new v4l2 framework
that is causing this.

hermann pitton wrote:

Nope -- as I mentioned, dropping back to a snapshot from roughly 3 weeks
ago and applying Mike's patch works with both the nv and nvidia driver,
hence disproving that it is anything X related.

This issue seems to have been resolved since having updated to the ALSA
1.0.19 release from a couple of weeks ago (which literally contained a
zillion fixes, so I'm not going to bother trying to figure out which one
might have been the fix)..

At least the digital demod takes all without any hick up and does not
report what it is doing next. The messages are sent from the saa713x.

Open simultaneously is known since ever.
Harder it becomes here.
http://bugzilla.kernel.org/show_bug.cgi?id=10036

Seems I must reread it all or you point me to something to reproduce it.

BTW, using mplayer causes troubles for some apps to get the hardware
Overlay back, not overlay-preview, but not for tvtime.

The latter I can't confirm so far and, IIRC, Mauro said he does not
expect that it is related to our driver.

This would need closer insight and I can't reproduce it either on
saa7131e. The saa7134 has some specials for mute, not to talk about the
saa7130.

It should not be related to any ALSA versions, except you might be
talking about your sound card mixer.

The hardware mute always happens in saa7134-tvaudio and saa7134-alsa
only uses an exported symbol for that (Ricardo for mythtv).

The analog and i2s/dma sound can be muted separately by different
registers. The i2s/dma was previously always enabled for possible mpeg
encoders waiting for it, but this was changed in 2005 for all the
cardbus and others without any analog audio out. Maybe not all
saa7133/35/31e chips are equally covered, but I can't tell ;)

Hermann

OK.  With Hans' v4l-dvb-kworld driver, MythTV works, but with a big
caveat.  I have to unload the saa7134-alsa, saa7134-dvb, saa7134 and
tuner-simple modules, reload them and then run tvtime before MythTV
works.  If I do things in any other order, MythTV doesn't report any
errors, but it only records static.  In addition, if I run MythTV
before running tvtime, tvtime only shows static too until I reload the
modules.  This pattern held for 3 reboots.

CityK,

It seems I missed your email with the detailed logs.

Let's go by parts: Let's first try to solve the issue with the i2c gate, in
order to have both analog and digital modes to work properly. After having it
fixed, we can go ahead and check if the issue with some softwares are a
regression at the driver (or at v4l core) or something else at X space.

Could you please send me the logs of the driver of it working (old tree +
Mike's patch) and not working (with current tip)?

Please load it with the following debug options:
	modprobe saa7134 i2c_scan=1 video_debug=3 core_debug=1 i2c_debug=1

Btw, I have one PCMCIA board with me that stopped working with Hans patches
applied at tip. So, I suspect that some regression were caused by the i2c
conversion. I'll use this board to debug the driver.

Cheers,
Mauro

Also, please test the new code I made available at:

	http://linuxtv.org/hg/~mchehab/saa7134

It contains a code that will hopefully fix this issue.

The issue here seems to be unrelated: sometimes, tda8290/tda8275 is not
detected on my MSI TV@nyware A/D NB device. The chip simply stops answering at
address 0x4b (7bit notation). Not sure why and not sure if this is a regression
or not. Anyway, while debugging it, I noticed that the i2c gate control for
those devices were broken. I wrote some patches to fix (also at the same tree),
but this didn't solve the issue (it will probably solve another issue with
sleep/wakeup on this device).

Michael,

Please take a look at the tda8290/tda827x patches

Mauro

It took me some time today to bisect and trying to see what's going wrong with
some userspace apps. 

At the end, I discovered that changeset 10240 fixes a bug that affected some
userspace bad behaviour of setting defaults to zero, if a control is not found.

Due to that userspace bad behaviour, both tvtime and xawtv were using 0 for all
video controls (brightness, contrast, color, hue). The practical effect is that
a black image were displayed.

The fix were as simple as putting all controls at 50%.

Could this be your case also?

Mauro, I know you are waiting for CityK, but I can report so far that I
never did see that black screen going away by adjusting the controls and
never had that black screen.

Tvtime and xawtv were always working under my conditions so far.

The very old troubles, like tda9887 not present after boot on my md7134
devices with FMD1216ME MK3 hybrid, and the even unrelated issue with the
tda10046 not properly controlled anymore after suspend/resume,
are unchanged on your current saa7134 attempt, but also no new issues
visible so far.

Hermann

BTW, just to remember.

Tvtime with signal detection on shows a blue screen without signal.
With signal detection off, just good old snow.

The tda8275/75a shows a black screen without having lock, not even snow,
if it should be related.

Sorry, to add one more about "black" screens :)

Without the tda9887 loaded, the FMD1216ME MK3 hybrid also shows a black
screen, but it is slightly different from the fully black screen of the
tda8275, which is in fact an overlay like the blue screen on tvtime. It
has some white points visible and on some channels even _very_ decent
ghosting of TV.

The status of the tda9885/6/7 on the TUV1236D is still not clear to me,
until I see debug enabled on it for switching TV standards and just
nothing ever changes.

Good to know.

Ok, let's go by parts:

1) We need to know the sequence that enables tda9887 on md7134/fmd1216me, in
order to fix it. If someone has fmd1216me, please write me in priv or help us
to fix the code for it.

2) I bet that the issue with tda10046 is related to firmware loading. I made
some tests with a TV @nyware cardbus device that has a tda10046 + tda8290/tda8975.

What happens is that this device supports two type of firmware loads. The first
one requires an i2c eeprom with the firmware inside. The driver just writes
0x04 at register 0x07 and waits for some time. The hardware does the firmware load.

On the second mode, firmware bytes are transferred from the driver into the tda10046 memory.

At the tests I made here, on both modes, the i2c bus can't have any other
traffic during the firmware load. Otherwise, an invalid firmware will be loaded
and tda10046 will hangup.

I've started to implement some locks at saa7134 driver (on my saa7134
experimental tree), but it is not finished yet. I didn't touch at the sleep code yet.

So, the tda9887 or the PLL are configured wrongly.

Probably, tda9887 is configured for STD/M, instead of STD/BG. Fixing tda9887
will also fix this issue.

Just for that one for now, I'll try on the other subjects later.

I don't have any TUV1236D based device, but CityK and maybe Michael on
the Kworld _ATSC_ ! 110/15.

>From the photo provided by CityK, there is clearly a 24pin Philips
device within the IF section of this tuner, which I guess is a tda9885
NTSC only and nothing else.

As mentioned before, they can be strapped on one pin to be NTSC
(System-M) only without needing _any_ i2c programming according to the
data sheets.

With the reports so far, after years, either the tda9887 module is just
fake loaded, even that fails, or nothing ever happens, or something
happens on i2c we don't have clear.

So I would like to see if there is ever valid i2c traffic to that
tda988x device on that tuner or never...

Hermann

Urgh, not to add more confusion here at least.

Good old snow means the analog signal is perfect.

I stopped since long to connect a real signal to it surfing the grounds
on my stomach, but it is for sure working then and the pll is always
fine.

Ah, ok. So, now, we just need CityK (or someone else with ATSC 115) to confirm
that everything is fine on their side. This patch may also fix other similar
troubles on a few devices that seem to need some i2c magic before probing the
tuner.

Maybe we don't need any extra programming for tda9885, but it won't hurt to
reprogram it to the right state.

Just tried the latest hg and I can confirm that both an ATSC 110 and
115 work with tvtime
and ATSC.

You tried the latest tree at http://linuxtv.org/hg/v4l-dvb or my saa7134 tree
(http://linuxtv.org/hg/~mchehab/saa7134)?

In the first case, could you please confirm that it works fine also with the saa7134 tree?

Thanks, Jonathan. I'll merge the saa7134 patches then. The method I used
previously is better fitted when we know how to enable and disable the i2c
gate, but, for ATSC 115, we only know how to open the gate.

Mauro, for the record, it is about chapter 8.16 on page 13 in the
current tda9885/6 datasheet and the voltage delay in that case on page
14. It is the same for tda9887.
http://www.nxp.com/#/pip/pip=[pip=TDA9885_TDA9886_3]|pp=[t=pip,i=TDA9885_TDA9886_3]

Here is a link to the early discussions by Curt and CityK.
http://lists.zerezo.com/video4linux/msg09088.html

This has also the link to the high resolution photograph of the open
tuner. We see a video IF and sound IF SAW filter and can assume it has
OSS sound. No tda7040 radio stereo separator is visible so far.
(on your CTX925 it is too)
http://www.nxp.com/#/pip/pip=[pip=TDA7040T_CNV_2]|pp=[t=pip,i=TDA7040T_CNV_2]

The third SAW filter is for ATSC.

Let's keep in mind, the tda9887 on the md7134 devices with FMD1216ME MK3
hybrid it not loaded and uninitialized after boot and it needs a driver
reload.

I tried both trees with my ATSC 115.  

The v4l-dvb did not work.  tvtime showed only a blue screen,
presumably due to lack of a signal.  The last commit in the tree was
as follows:

The saa7134 worked.  MythTV eventually worked too, but I had to do the
"unload/reload modules and run tvtime" procedure I reported earlier
when I tried Hans' kworld tree.

guess that is why CityK reported already on that always with a _cold_
boot too, as discussed.

Forget about mythtv on such testing.

You likely will never catch a rabbit this way, but it is fine for to
count them all after ...

Ok. I've merged from saa7134 tree. This is the patch that changed the open gate
for ATSC115 (and other saa7134 devices whose i2c gate open sequences are known):

Maybe this is a race condition I have here with tda1004x. With tda1004x, the i2c
bus shouldn't be used by any other device during the firmware transfers,
otherwise the firmware load will fail, and tda1004x goes into an unstable
state. With this device, it even affects all subsequent i2c acesses. The only
alternative to recover tda1004x is to reboot the card (e. g. with my cardbus
device, I have to physically remove it and re-insert).

What happens is that some softwares (including udev) open the device, and send
some VIDIOC_G_TUNER in order to check some tuner characteristics. However, this
command generates some i2c transfers, to retrieve signal strength. If this
happens while the firmware is being loaded, the bug occurs.

In order to fix, a careful review of all locks on the driver is needed. We will
likely need to change the demod interface for the boards that have this
trouble, in order to be aware of when a firmware transfer started.

This lock review is currently on my TODO list.

To be sure that this is the case, could you please add this on
your /etc/modprobe (or at a file inside /etc/modprobe.d):

	options nxt200x debug=1
	options tuner-simple debug=1
	options tuner debug=1
	options dvb-core frontend_debug=1

And test again, sending us the produced logs when the device works and when it
breaks. I guess we'll discover some tuner dmesg's in the middle of the firmware
load sequence.

As a reference, this is the logs for the race condition with tda1004x:

DVB: registering frontend 0 (Philips TDA10046H DVB-T)...
tda1004x: setting up plls for 48MHz sampling clock
tda1004x: found firmware revision ff -- invalid
tda1004x: trying to boot from eeprom
tda829x 1-004b: tda8290 is locked, AGC: 241
tda829x 1-004b: adjust gain, step 1. Agc: 241, ADC stat: 108, lock: 128
tda829x 1-004b: setting tda829x to system B
tda827x: setting tda827x to system B
tda827x: AGC2 gain is: 1
tda829x 1-004b: tda8290 not locked, no signal?
tda829x 1-004b: tda8290 not locked, no signal?
tda829x 1-004b: tda8290 not locked, no signal?
tda829x 1-004b: adjust gain, step 1. Agc: 236, ADC stat: 0, lock: 0
tda829x 1-004b: adjust gain, step 2. Agc: 128, lock: 0
tda829x 1-004b: adjust gain, step 3. Agc: 128
tda829x 1-004b: setting tda829x to system B
tda829x 1-004b: setting tda829x to system B
tda1004x: found firmware revision ff -- invalid

The firmware load stops at the last message. Notice that, during the firmware
transfer, the tuner status were checked. This generated a breakage at the i2c
transfer. Maybe we'll need a sort of locking between tuner and demod i2c access
to avoid such troubles.

Cheers,
Mauro

Here are my logs.  They are annoteded in-line with the actions I took.
I need to add that the results with MythTv aren't always consistent.
Sometimes it works right away when I don't expect it to and sometimes
it doesn't work after the reload when I do expect it to.  The results
shown below are what happens most of the time -- MythTV doesn't work
until the modules are reloaded and tvtime is run.

Cold booting.

Ok, I did a diff between the two logs. On the first module probing,
saa7134-alsa were probed before than on the second log. I don't think that this
would be relevant for this issue.

However, on both logs, we see a tuner write to the wrong address (0x0a, instead
of 0x61):

Aparently, the second tuner call setting went to the proper i2c address:

It seems that some parts of saa7134 (or frontend) is overriding the i2c
address,to write at the demod, causing a mess. Another alternative would be
some bug at v4l subdev interface.

I'll seek at saa7134 code to see who is causing this error.

Cheers,
Mauro

Ok, I found the bug. It is inside tuner-simple code. It is caused due to a hack for TUV1236.

I've just committed a fix for it:
	http://linuxtv.org/hg/v4l-dvb/rev/34ec729ed1a7

Please test.

In limited, remote testing -- it works!  It also works on my
production MythTV backend with 2 ATSC 115s.  This is the first time
analog has ever worked on both of those cards at the same time.  I'll
do more testing over the weekend.  Thanks very much, Mauro, Hans and
everyone else involved.

I didn't get to test as much as I'd hoped but I did do some.  The
fixed analog support on my ATSC 115s worked great.  Thanks again.

Can I remove my v4l-dvb-kworld tree? I gather that it is now fixed in the

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.

Mike Krufky

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

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)

It won't fix the antenna input selection controlled from the digital

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

for me the same and I can't test on these.
The Pinnacle 310i seems to have the LNA support broken, can't test.

If manufacturers would confirm to the Philips/NXP drivers and what
should be in the eeprom, that would be possible on GNU/Linux too.

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 :)

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!

OK, I couldn't help myself and went ahead and tested it. It seems fine, 
so please test my tree:

Let me know if it works. If it does, then I'll ask Mauro to pull from my

Absolutely! :-)

FYI: I have a patch, but I won't have time to test it until Friday. You 
should get something from me then. The main change was actually to the 
saa6752hs.c i2c module (it wasn't yet converted to v4l2_subdev), and I 
need to test that first with my empress card.

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.

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 ;)

Yes, I can. I'll do saa7134 since I have an empress card anyway. It

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

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.

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.]

KWorld ATSC 115 all static

[Josh Borke]

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
