Ah, I see.   The whole thing is a tuner, and the label that I thought said
"ERIT" actually says "SERIT".  Yes, it does have a label on it, I should
have given you that up front.  I had searched for it on the internet and
decided that it didn't mean anything.  Thanks so much for your help.

The label reads SP1514LHb  D0943B

If I follow your decipher instructions that means:

1: DVB-S
5: 16cc
1: Unsure, but it has an LNB in and an LNB out, so I guess it does have
loop through?
4: Si2109
L: Si labs
H: Horizontal
b: Lead free

So I'm looking for some code to enable an Si2109 tuner?

Thanks again,

Paul

I'm looking through the dm1105 code that I have in 2.6.33-rc4.  I have a
block that reads:
                dm1105dvb->fe = dvb_attach(
                        si21xx_attach, &serit_config,
                        &dm1105dvb->i2c_adap);
                if (dm1105dvb->fe)
                        dm1105dvb->fe->ops.set_voltage =
                                                dm1105dvb_set_voltage;

I have looked through the code for si21xx.c, and I see that you wrote that
as well.  You have been very busy!!  

I did rmmod si21xx, then insmod si21xx debug=1.

I then rmmod dm1105, insmod dm1105.

Does this shed any light on the matter for you?

Sorry, that is a bit beyond me.

If I understand correctly, I'm looking for the top right pin from the
tuner when I'm looking at the side of the card that has all the chips on
it.  I can see that, and there are a number of traces that run from there
to the DM1105, and also a few that run to other components on the card. 

I'm assuming I need to follow the topmost of the traces that go to the
DM1105, and see which pin on the DM1105 it goes to.

My eyesight isn't that good...but I have a magnifying glass.  If I follow
the topmost of the traces it looks to run to the rightmost pin on the top
row of pins on the DM1105, when the writing on the DM1105 is the right way
up.  I didn't find a data sheet for the DM1105, so I can't tell if that is
a GPIO pin or not.

The next trace down from the top right on the tuner appears to end without
connecting.  It ends in a small brass circle, and doesn't appear to go
through to the back of the board and connect anywhere.  The next one below
that goes to the fifth pin in from the right hand end of the top row on the
DM1105.

Am I doing the right thing here - does this make sense?

I've drawn on the photo so you can see what I'm doing.  Refer:
http://planar.id.au/Photos/img_1964%20%28copy%29.jpg.  The far right blue
line comes from the top most right hand pin on the tuner, runs under the
board at the brass circle, and comes out again to join on to the rightmost
pin.  The next blue line in is the one going to the fifth pin, it is the
third track down coming from the tuner.  In between the two is a track that
appears to go nowhere.  I've marked in white roughly where they are coming
out of the tuner.

Thanks again for all your help,

Paul

Well, as I understood, GPIO15 drives reset for demod.
dm1105 driver needs little patching.

Igor,

Not to hassle you, I'm sure you're very busy.  Is this something I could
undertake myself?  If so, which driver would you recommend I copy from - I
saw on the list that some drivers do their own GPIO management, and others
use a generic GPIO layer.  I presume we'd need to use the generic layer?

Also, from your explanation it sounds like we need to set GPIO 15 to true
before we attempt to attach.  Is that correct?  From my reading there are
two GPIO registers (8 bits each), so we'd be bit masking bit 7 in the
second GPIO register to 1, then sending that GPIO to the card?

Thanks for any tips,

Paul

As you can see there is two 32-bit registers. First for values, second
for controls. Control means 0 for output and 1 for input.
If I remember it is 17 GPIO lines only.

/* GPIO Interface */
#define DM1105_GPIOVAL				0x08
#define DM1105_GPIOCTR				0x0c

Thanks for all your help, I understand better now.  I have moved to code
like that at the bottom.  It still doesn't work, but feels a lot closer.

Before I keep playing with values, I want to check I'm on the right track.
Does it look right?  Specific questions:
1. I see there is a hw_init function.  Should I be using that?  I put the
logic into fe_attach because there was already card-specific logic in
there.  But this feels like hw initialisation.  

2. Should I set the control to input or output?  I'm assuming input = 1.

3. Would pin 15 be numbered from the left or right - is it 0x4, or 0x2000?

Thanks,

Paul

Some things are missed, like keep GPIO15 high in set_voltage function.

Hi Nameer,
You can modify sended by me patch to guess GPIO pin. Simply try all of them, it is only 17. 
Just replace all appearances DM1105_GPIO(15) with number you want.

Hi Mauro,
The patch should be applied.
Do I need to do something, it means apply to a tree and send pull request?

No luck here either, still working on it.
My plan is to solder som wires on strategic points on the board and 
debug i2c and other activity with an oscilloscope. Will probably start 
next week.

I didn't test patch in real hardware.
But I can connect GPIO14 and GPIO13 to SCL and SDA in any dm1105 card and test whether it works.
Then I will ask you to test also.

A little progress update.
A modded card with connections made between the dm1105 i2c pins and the 
gpio pins is detected as a dm05 and seems to work, at least with kernel 
2.6.33 and liplianin modules.
This suggests that the i2c bitbanging is not working properly.

Think I solved it.
The dm1105_getsda and dm1105_getscl functions need to mask out the other 
GPIO bits.
I hacked the code to return 1 if corresponding GPIO set, and 0 if not 
set. That did the trick. Now the frontend registers and /dev/dvb is 
populated. :)
Haven't done any tuning yet.

Yep. No succesful tuning at the moment. There might also be an issue 
with the reset signal and writing to GPIOCTR, as the module at the 
moment loads succesfully only once.
As far as I can make out, the LNB power control is probably GPIO 16 and 
17, not sure which is which, and how they work.
GPIO15 is wired to tuner #reset

A little tweaking produced the required voltages for the LNB:

switch (voltage) {
case SEC_VOLTAGE_18:
dm1105_gpio_set(dev, GPIO16 | GPIO17);
break;
case SEC_VOLTAGE_13:
dm1105_gpio_andor(dev, GPIO16 | GPIO17, GPIO17);
break;
default:
dm1105_gpio_clear(dev, GPIO16 | GPIO17);
break;
}

But unfortunately tuning is still failing. Could it be an issue with the 
21xx driver? I will read up on the Si2109.

Since the tuner at hand uses a Si2109 chip, VSTATUS 0x01 and 0x02 would 
indicate that blind scanning is used. Blind scanning is a 2109/2110 
specific function, and may not very usable since we always use initial 
tuning files anyway. 2109/10 also supports the legacy scanning method 
which is supported by Si2107708.

Is the use of blind scanning intentional?

Sorry, my bad. Mixed up the registers.
Got a VSTATUS: 0x0b once. Mostly I'm getting 0x01 and 0x02. Sometimes 
0x00 and 0x03

Yes, of course, it's intentional. Why not?
User has freedom to make little errors in channels.conf file. Also the chip didn't support DVB-S2. 
And last, has who si2107/08 ? My chip is si2109.

I agree, it's best to use the hardware features. I was worried that I 
may be getting bad i2c data.
If I understand you correctly, you have a working Si2109 frontend driver?
Here's what I'm getting:
Added a few printouts to si21xx.c

        u8 signal = si21_readreg(state, ANALOG_AGC_POWER_LEVEL_REG);
        dprintk("%s : FE_READ_STATUS : AGC_POWER: 0x%02x\n", __func__, 
signal);

        si21_readregs(state, LOCK_STATUS_REG_1, regs_read, 0x02);

        reg_read = 0;

        for (i = 0; i < 7; ++i)
                reg_read |= ((regs_read[0] >> i) & 0x01) << (6 - i);

        lock = ((reg_read & 0x7f) | (regs_read[1] & 0x80));

        dprintk("%s : FE_READ_STATUS : VSTATUS: 0x%02x\n", __func__, lock);
        dprintk("%s : FE_READ_REGS : REGS[0]: 0x%02x\n", __func__, 
regs_read[0]);
        dprintk("%s : FE_READ_REGS : REGS[1]: 0x%02x\n", __func__, 
regs_read[1]);

So, we have signal and sometimes we are getting carrier also.
What worries me most is the FE_READ_REGS : REGS[1]: 0x60
According to the datasheet this register 0x10 Lock status 2,  is RCVL 0 
0 0 0 0 BSDA BSDO so 0x60 would seem meaningless.

Same results using szap.

Signal but no lock.
Any ideas?

It is likely. In that case try different delays like that
	dev->i2c_bit.udelay = 16;
	dev->i2c_bit.timeout = 200;

The driver is working. It's for shure. I tested PCI and USB cards with this chip.

I think the LNB voltage may be a little to high on my card, 14.5V and 
20V. I would be a little more happy if they were 14 and 19, 13 and 18 
would be perfect.
Anyways, as Igor pointet out, I don't have any signal from the LNB, 
checked with another tuner card. It's a quad LNB, and the other outputs 
are fine. Maybe it's' toasted from to high supply voltage! I little word 
of warning then.
Anyways, here's my tweaked driver.

Re: DM1105: could not attach frontend 195d:1105

[Hendrik Skarpeid]

A little update on the matter.

These cards are broken!

It seems that the card is designed for a different NIM than what is 
actually on the cards.
The worst problem is 3.3V power supply for the digital portion of the 
NIM. This powers the 3.3V IO on the Si2109, and it is unconnected! This 
effectively disables all the IO that is not open drain like i2c. That is 
why you will not get any 22khz tone from these cards.

Luckily, I think I have found a way to fix it. The card is now tuning, 
and the 22khz tone is working.
The LNB voltage is a little high, but that can be fixed by adding or 
replacing a resistor.
I have not tried to watch TV yet, so I am not certain if it is at all 
possible to get these cards into working order.

I will try the fix on a couple of boards and test them, and if it is 
successful, I will post a howto on the v4l wiki. Be warned though, it 
will involve the use of a soldering iron.

Here is reworked patch for clear GPIO's handling.
It allows to support I2C on GPIO's and per board LNB control through GPIO's.
Also incuded support for Hendrik's card.
I think it is clear how to change and test GPIO's for LNB and other stuff now.
To Hendrik:
	Not shure, but there is maybe GPIO for raise/down LNB voltage a little (~1v).
	It is used for long coaxial lines to compensate voltage dropping.

Hi Igor,

I have a brandless DVB-S tv tuner card also, with a dm1105n chip. I was 
getting the "DM1105: could not attach frontend 195d:1105" message with 
the latest kernel also, but I applied this patch to the dm1105 module 
and now the card's being recognised  (though is still listed as an 
ethernet controller with lspci)

My dmesg output is:

dm1105 0000:01:05.0: PCI INT A -> GSI 17 (level, low) -> IRQ 17
DVB: registering new adapter (dm1105)
dm1105 0000:01:05.0: MAC 00:00:00:00:00:00
DVB: registering adapter 0 frontend 0 (SL SI21XX DVB-S)...
Registered IR keymap rc-dm1105-nec
input: DVB on-card IR receiver as 
/devices/pci0000:00/0000:00:1e.0/0000:01:05.0/rc/rc0/input6
rc0: DVB on-card IR receiver as 
/devices/pci0000:00/0000:00:1e.0/0000:01:05.0/rc/rc0

The card is one of these:
http://www.hongsun.biz/ProView.asp?ID=90

Scanning doesn't appear to give me any results.  Should this be working? 
  Anything I can do to test the card out for you?

Cheers,
Matt.

Hi Matt,
Is there any label on tuner can?
Have you a close look picture of PCB ?

Hi Igor,

The label on the tuner can is SP1514LHb S1009, so I'm guessing this is a 
near-identical card to the one that Paul was asking you about in January 
of last year, e.g:

>  1: DVB-S
>  5: 16cc

Here are two images I took of the card:

A view of the entire board:

http://matt.vicke.rs/pics/pcb_full.jpg

And here is a closer view of the board between the tuner and the dm1105n 
chip.

http://matt.vicke.rs/pics/pcb_detail.jpg

With your patch and the card=4 parameter the card is recognised, and the 
dvb device created. Scanning will run (I'm attempting to locate channels 
on Optus D1, which I can successfully scan using a set top box, so the 
dish is correctly aligned), but the card reports tuning failed on all of 
the Optus D1 frequencies that I attempt. I also tried running w_scan but 
had no success.

Cheers,
Matt.

Hi Matt,

Did you read this post?
http://www.mail-archive.com/linux-media@vger.kernel.org/msg17269.html
It seems the card needs some soldering :(

I'm not sure if this patch is still valid or not, and if it should or not be
applied, as there were several discussions around it. As a reference, it is stored
at patchwork with:
	X-Patchwork-Id: 279091

And still applies fine (yet, patchwork lost patch history/comments and SOB).

Igor, could you please update me if I should apply this patch or if the patch got
rejected/superseeded?

Thanks!
Mauro.

Accordingly datasheet possible demod addresses are 0x68, 0x69, 0x6a, 0x6b only.
Possibly there is some DM1105 GPIO drives reset for demod.
I assume it is last (26, top right if you look from card elements side) pin on tuner.
You can visually trace way from can tuner. Or use multimeter.

Igor,

Photos:
1.  Front of card.  You can see the DM1105 in the foreground.  There are
no other significant looking chips on the card.
http://planar.id.au/Photos/img_1964.jpg

2.  Back of card - as you can see, there aren't a lot of places where a
lot of pins are connecting - mainly the DM1105 itself
http://planar.id.au/Photos/img_1965.jpg

3.  With the top metal plate removed, and with the other end of the card
in better focus.
http://planar.id.au/Photos/img_1966.jpg

Is it likely that there is a tuner under the card labelled "ERIT"?  To
take it off I have to unsolder some stuff - I can do that, but I reckon
it's only 50% chance the card will work again when I put it back together -
my soldering isn't so good.

Thanks heaps for the assistance.

Paul

No need to unsolder. I see a Serit can tuner. There is a sticked paper with a label on right side 
of the tuner. It must contain something like "sp2636lhb" or "sp2633chb". Please provide me text of 
label.

DM1105: could not attach frontend 195d:1105

[paul10]

I bought a DVB-S card to attach to my mythtv setup.  I knew it was perhaps
not going to work, and I only spent $15 on it.  However, based on the info
the guy on eBay provided, it had a pci address of 195d:1105, which I could
see some people had cards that were working.

The card itself is a no-name jobby.  I can see the DM1105 chip on it, I
can't see any other chips with any significant pin count (lots with 3 - 8
pins, but nothing with enough to be important).  There is a metal case
around the connectors that might be hiding a frontend chip of some sort,
but it doesn't seem to have enough connectors in and out to be doing much
that is important beyond just providing connectivity to the LNB.

I've got the latest kernel (2.6.33-rc4) and I've checked the code and it
looks like the latest DM1105 code.  When booting I get:

[    9.766188] dm1105 0000:06:00.0: PCI INT A -> GSI 20 (level, low) ->
IRQ 20
[   10.047331] dm1105 0000:06:00.0: MAC 00:00:00:00:00:00
[   12.464628] dm1105 0000:06:00.0: could not attach frontend
[   12.479830] dm1105 0000:06:00.0: PCI INT A disabled

With lspci -vv I get:
06:00.0 Ethernet controller: Device 195d:1105 (rev 10)
        Subsystem: Device 195d:1105
        Control: I/O+ Mem+ BusMaster- SpecCycle- MemWINV- VGASnoop-

        Interrupt: pin A routed to IRQ 20
        Region 0: I/O ports at b000 [size=256]

No DVB devices are created.

I see from other people using a card with this chipset that there probably
would be a tuner/frontend as well as the DM1105. I've also tried card=5 in
the insmod parameters.

It seems to me that the card probably has a tuner/frontend on id different
from the Axess board, but I'm not sure how I'd work out what that is.  Is
it possible that it doesn't have any chips on it other than the DM1105? 
Should I take the board apart a bit to find out?

Thanks,

Paul

Hi Paul,

Frontend/tuner must lay under cover.
Subsystem: Device 195d:1105 indicates that there is no EEPROM in card.
If you send some links/pictures/photos then it would helped a lot.
Is there a disk with drivers for Windows?
Also I know about dm1105 based cards with tda10086 demod, those are not supported in the driver 
yet.
