I also got the unbranded dm1105 card. I tried the four possible i2c addresses, just i case. Noen worked of course. Then I traced the i2c pins on the tuner to pins 100 and 101 on the DM1105.
These are GPIO pins, so bit-banging i2c on these pins seems to be the solution.
scl = p101 = gpio14
sda = p100 = gpio13

Here is the patch to test. Use option card=4.

	modprobe dm1105 card=4

Hey Igor,
I'm getting the same error:

Did you get your one to work.

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.

scl = p101 = gpio14
sda = p100 = gpio13
Here is the patch to test. Use option card=4.
    modprobe dm1105 card=4
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.

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.

Do you cut connections between dm1105 i2c pins and the gpio pins you make earlier?

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

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.

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.

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

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?

Quoted 4 lines
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.

It is likely. In that case try different delays like that

	dev->i2c_bit.udelay = 16;
	dev->i2c_bit.timeout = 200;

Quoted 1 line

If I understand you correctly, you have a working Si2109 frontend driver?

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.

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.

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
New patch to test
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.

Anyways, here's my tweaked driver.

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

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:

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,

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

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:

Quoted 8 lines

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

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.

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.
