I'm not sure why you had to fake anything? What I'd like to know is simply if my first patch had any negative effect on other cards. because I simply don't have that Asus My Cinema analog only in question. To recap, you previously announced a patch, tested by Daro, claiming to get the remote up under auto detection for that device and I told you having some doubts on it. My first patch was not actually tested by Daro. What he tested was loading the driver with card=146. At first I thought it was equivalent, but since then I have realized it wasn't. That's the reason why the Tested-by: was turned into a mere Cc: on my second and third patches. Mauro prefers to have a fix for that single card in need for now. Since nobody else cares, For now, see above, I can confirm that your last patch for that single device should work to get IR up with auto detection in delay after we change the card such late with eeprom detection. The meaning of that byte in use here is unknown to me, we should avoid such as much we can! It can turn out to be only some pseudo service. If your call for testers on your previous attempt, really reaches some for some reason, I'm with you, but for now I have to keep the car operable within all such snow. That I understand. What I don't understand is: if you have a SAA7134-based card, why don't you test my second patch (the one moving the call to saa7134_input_init1 to saa7134_hwinit2) on it, without faking anything? This would be a first, useful data point. sorry, the snow fall did not stop and we will need trucks next day to get it out of town. No place left. I did not reread any single line of code until now, but told you that Roman has tested a equivalent patch on his P7131_ANALOG already and I can confirm that it also had no side effects on a FlyVideo3000 card=2. For now, I would at least need some time to see, if input_init can be decoupled from all other hardware init, what you seem to suggest, and looking closer to Mauro's concerns. Thought you are asking for some test with a i2c remote next to confirm your analysis there. No such card in any machine currently, but can be done.

If you could please test both patches I sent (first one on 2010-01-27, second one on 2010-01-30, both should be in your mailbox) and confirm that they both work for you (so you no longer need to pass card=146 to the driver), that would be great. Mauro doesn't seem to be willing to apply the first patch, but for future reference I would still be interested to know if it would work at least in your case.

Re: [PATCH] saa7134: Fix IR support of some ASUS TV-FM 7135 variants
Jean Delvare wrote: Hi Mauro, Sorry for the late answer. I'm tracking so many things in parallel... No problem. What happens is that the saa7134_board_init1(dev) code has lots of gpio codes, and most of those code is needed in order to enable i2c bridges or to turn on/reset some chips that would otherwise be on OFF or undefined state. Without the gpio code, done by init1, you may not be able to read eeprom or to detect the devices as needed by saa7134_board_init2(). I don't think I ever said otherwise. I never said that init1 as a whole only cared about GPIO IR. That's what I said of function saa7134_input_init1() and only this function! Ah, ok. I suspect I miss-understood when you talked about init1, since 99% of the patches about init1 are related to board init, and not to input init. My first proposed patch didn't move all of init1 to init2. It was only moving saa7134_input_init1 (which doesn't yet have a counterpart in init2), and it is moving it from the end of init1 to the beginning of init2, so the movement isn't as big as it may sound. The steps saa7134_input_init1() is moving over are, in order: * saa7134_hw_enable1 * request_irq * saa7134_i2c_register So my point was that none of these 3 functions seemed to be dependent on saa7134_input_init1() having been called beforehand. Which is why I strongly question the fact that moving saa7134_input_init1() _after_ these 3 other initialization steps can have any negative effect. I wouldn't have claimed that moving saa7134_input_init1() _earlier_ in the init sequence would be safe, because there's nothing obvious about that. But moving it forward where I had put it did not seem terrific. I agree. In thesis, after board-specific init1 and init2, the device should be in good health and all the needs for IR should already be available. The only point that requires a double check is at the suspend function (as someone may try to suspend the machine in the middle of the board setup). I really would like a few users of this driver to just give it a try and report, because it seems a much more elegant fix to the bug at hand, than the workaround you'd accept instead. Seems fair to me. That's why I'm saying that, if in the specific case of the board you're dealing with, you're sure that an unknown GPIO state won't affect the code at saa7134_hwinit1() and at saa7134_i2c_register(), then you can move the GPIO code for this board to init2. Moving things between init1 and init2 are very tricky and requires testing on all the affected boards. So a change like what your patch proposed would require a test of all the 107 boards that are on init1. I bet you'll break several of them with this change. Under the assumption that saa7134_hwinit1() only touches GPIOs connected to IR receivers (and it certainly looks like this to me) I fail to see how these pins not being initialized could have any effect on non-IR code. Now, i suspect that you're messing things again: are you referring to saa7134_hwinit1() or to saa7134_input_init1()? I suspect that you're talking about moving saa7134_input_init1(), since saa7134_hwinit1() has the muted and spinlock inits. It also has the setups for video, vbi and mpeg. So, moving it require more care. (btw, IMO all those *init1/*init2 names were a terrible choice) Now, please don't get me wrong. I don't have any of these devices. I've posted that patch because a user incidentally pointed me to a problem and I had an idea how it could be fixed. I prefer my initial proposal because it looks better in the long run. If you don't like it and prefer the second proposal even though I think it's more of a workaround than a proper fix, it's really up to you. You're maintaining the subsystem and I am not, so you're the one deciding. Please, don't excuse yourself. You're right proposing a patch to help the user. Thanks for that. From my side, I just want to make sure that we won't add any regressions with other boards. Experience shows that touching at those init sequences (especially at the board init1/init2) cause lots of problem. For example, before the i2c redesign, there were several GPIO's inside init2. Due to that, if the i2c module got loaded before init2, several boards would fail. On those boards, people were required to load the modules on an specific order with some boards (and sometimes unload/reload an i2c driver), to be sure that the i2c devices would get properly initialized. Due to that, several boards didn't work if the drivers were compiled builtin. Also, there are some cases where it were impossible to have all saa7134 devices working on a machine with multiple saa7134 devices. During the time the i2c changes got merged, those GPIO sequences were moved to init1, but this broke several devices, and the init sequences needed to be manually adjusted for those. I don't doubt that are there still a few broken. At least now, the

For now, I would at least need some time to see, if input_init can be decoupled from all other hardware init, what you seem to suggest, and looking closer to Mauro's concerns. Thought you are asking for some test with a i2c remote next to confirm your analysis there. No such card in any machine currently, but can be done.

Some variants of the ASUS TV-FM 7135 are handled as the ASUSTeK P7131
Analog (card=146). However, by the time we find out, some
card-specific initialization is missed. In particular, the fact that
the IR is GPIO-based. Set it when we change the card type.
We also have to move the initialization of IR until after the card
number has been changed. I hope that this won't cause any problem.
Hi Jean,
Moving the initialization will likely cause regressions. The reason why
there
are two init codes there were due to the way the old i2c code used to work.
This got fixed after the i2c rework, but it caused regressions on that time.
I don't think there is any problem with having two init sequences. You
need the EEPROM to identify some devices, you need I2C support to
access the EEPROM, and you need some initialization to get I2C
operational.
This doesn't mean that some adjustments to the exact sequence aren't
possible. In particular, I don't see what else can depend on IR being
initialized, so I can't really see what harm can be done in moving IR
init code _later_ in the sequence. Looking at saa7134_input_init1(), I
see that it is essentially setting up software parameters in the
saa7134_dev structure, there is almost no hardware access. Only for a
few cards, we change a couple bits in registers GPIO_GPMODE* and
GPIO_GPSTATUS*. I honestly can't see how doing this _later_ in the init
sequence could be a problem.
The proper way would be to just muve the IR initialization on this board
from init1 to init2, instead of changing it for all other devices.
Hmm, OK. I think it's wrong, but I'm not the one to decide. Patch below.
Mauro, I do agree with you that it is likely better to go a way with
minimum chances for regressions, also given the current testing base and
that only this single card is involved..
I admit I am very surprised that we apparently can't get anyone to test
changes to a driver that supports 176 different models of TV cards :(
Do we end up with something card specific in core code here?
After all, we know this is a no go.
Hartmut and me thought back and forth on how to deal with it for quite
some while, unfortunately Hartmut is not present currently on the list,
but he voted for to have a separate entry for that card finally too.
What we seem to have now is:
1. We don't know, if Jean's patch really would cause regressions,
but it is likely hard to get all the testing done. No problems with a
FlyVideo3000 gpio remote at the time Roman suggested it, but I had
not any i2c remote that time ...
I doubt it matters, given that saa7134_input_init1() only cares about
GPIO-based IR:
int saa7134_input_init1(struct saa7134_dev *dev)
{
(...)
if (dev-has_remote != SAA7134_REMOTE_GPIO)
return -ENODEV;
So the moving the call to this function should have no effect on boards
with I2C-based IR.
(...)
Given what is also in the cruft for bttv, I would not care too much for
that single card on that now also ancient driver, just print what the
user can do to escape and any google would find it quickly too. For Asus
it is a unique problem on that driver so far.
This isn't how we're going to make Linux popular.
I should have some time on Sunday afternoon for testing, if we should go
that way.
Any testing you can provide is very welcome, thanks.

The previous situation was, that this analog only card did use the entry of the Ausus P7131 Dual forcing card=78 without problems, but getting fake support for DVB-T announced and printing results of some fall through. 3. If we agree, that unique PCI subsystems should have highest priority for auto detection, in such a case, we likely could also set the PC-39 remote for the older card with USB remote. IIRC, that should survive the later change of the card caused by the work around eeprom detection later, and disable IR based on eeprom for the older then. To be honest, as pointed to already in the other thread around this, we should not try to become better than all others on m$ previously for some very small gain. We are already much, much better than drivers there, excluding each others, don't follow Philips/NXP eeprom rules and so on. We could just print something like use card=number to get the remote up too, if people, not reading the lists ;), hope to rely on auto detection in vain ... About all the LNA and IR mess we have for other manufactures, nobody talks about anymore ...
