Hauppauge HVR-900 HD and HVR 930C-HD with si2165

[Ulf]

Hi,

I know the topic Hauppauge HVR-900 HD and HVR 930C-HD with si2165 demodulator was already discussed http://permalink.gmane.org/gmane.linux.drivers.video-input-infrastructure/40982 and http://permalink.gmane.org/gmane.linux.drivers.video-input-infrastructure/46266.
Just for me as a confirmation nobody plans to work on a driver for si2165.
Is there any chance how to push the development?

Ulf

As far as I know there is none working with si2165 Linux driver.

Last week I dumped out simple sniff from initial tuning to DVB-T channel 
and parsed log - it was 1.1 MB after parsing - wow. I haven't analyzed 
if it yet, but if it appears it is si2165 which generates that much 
control I/O it could be big task to write driver.

Anyone has the idea if that amount of USB I/O traffic is caused by cx231xx ?

Hi,

FYI: The Si2168 driver is available from "dvbsky-linux-3.9-hps-v2.diff" 
inside. Maybe the Si2165 is similar?

It is DVB-S driver. HVR-900 is DVB-T and DVB-C.

Hi Guys,

I was contacted by someone claiming to be from "RSD" ??, named Danny 
Griegs, off-list, claiming I have the source code for sit2.c and cannot 
distribute it.

I want to make clear to everyone that the tarball I've provided only 
contains the C-equivalent of the "objdump -dx" output from the 
media_build-bst/v4l/sit2.o.x86 which is distributed officially by DVBSKY.

He claimed I had to pull the tarball off my site right away or face 
legal actions. I cannot understand this, and would like to ask you guys 
what you think. Obviously my sit2.c is too similar to their "licensed" 
sit2.c. And now these guys want to send a lawyer after me. What a mess. 
Should I laugh or cry. Any advice from you guys about this?

BTW: The hexdump of the sit2.o.x86 contains the string "license=GPL". 
Does that give me any rights to redistribute the re-assembled C-code ?

Mabbe better to take off and develop clean room reverse-engineered one 
from the sniffs. It should not be mission impossible, but took a much 
more time. Also, it could be possible to get datasheets from the chipset 
vendor in order to develop totally new driver.

I think that is grey area. There is a lot of binary modules having GPL 
license symbol whilst code is never shared...

there is www.rsd.de, which is abbreviation for rohde-schwarz-something
and to where that side is actually redirecting. so, they are
German-based company making DVB equipment and maybe if that's the same
RSD that Danny Griegs guy could be legit. however, nothing in the
binary you used proves they have any ownership over the binary or the
code compiled in it. so, you can ask them to show you their NDA with
Silicon Labs - after all they can't have access to that information in
the code without valid NDA with Silicon Labs.

so, there is no any guarantee that the code Max Nibble packed in that
binary is really his creation - he had a history of copy-left
practices - for example some time ago he tried to change the copyright
notice of code i released under GPL:

http://www.mail-archive.com/linux-media@vger.kernel.org/msg41135.html

as its main architecture was based on 'cx24116.c' made by Steven Toth
and others, even the work of 'ds3000' demodulator is quite different
and i made a lot of changes in the code leaving almost no resemblance
with 'cx24116.c'.

so, if you search the list there are few discussions about 'ds3000',
which i made and what Max Nibble did with it. also, Max Nibble is most
likely not his real name - those DVBsky-brand products are made by
Chinese company with the notorious name of "BestTunar" (yes, i didn't
make spelling error here). in any case that's issue between RSD/Danny
Griegs and Max Nibble, not between you and them. also, you can check
the originating IP of the email from RSD/Danny Griegs and ensure it's
not some of the many personalities of Max Nibble - he writes from IP
addresses located at Shenzhen, China.

i'm not an intellectual property lawyer, but what you did is at least
honest, i mean add notice:

"Max Nibble wrote the initial code, but only released it in binary
form. Assembly to C conversion done by HP Selasky."

and as far as you can tell the license of the code in the binary
module is GPL, because recently similar as what you did with that
driver happened with close-source driver made by me - that driver
included both open-source patches to GPL code and thus GPL and not
open-source module - all the code for it was submitted as several
patches to V4L and the submitter when i confronted:

http://www.spinics.net/lists/linux-media/msg65888.html

just said - i didn't know you made that:

http://www.spinics.net/lists/linux-media/msg65889.html

how convenient even thought 'modinfo' of the not-open-source module of
the initial driver lists the license as not-GPL and my name and email
as author and thus all changes that are made as part of that driver
are clearly why and who made them. anyway, i just move one, because it
seems even open-source community like V4L is no longer supportive of
the real authorship and don't care the things to be open-sourced in
some proper way, which is damaging for the community if you ask me.

so, as i mentioned on one of the links above, i don't see anything
wrong with clean-room reverse-engineering, even if that includes
disassembling of some binary as you did (a lot of open-source drivers
are made that way, when there is no publicly available datasheets), as
far as that is mentioned as note, which you did - i mean if you have
full understanding of the driver work then it's fine and you can even
maintain it and make no any notes, but otherwise it's just a bunch of
magic numbers that are reversed from the binary and nothing more, i.e.
you can't maintain and extent its functionality beyond what's in the
binary and totally ignore and give no credit to the one that made the
binary - let's say some of the chip initialization values needs to be
changed due to a bug. so, in the last case i guess that has more
negative impact than it helps, because even like my case that NDAs are
preventing the driver to become open-source that doesn't mean at some
point it wouldn't be open-sourced in a proper way, i.e. with
permission from those which intellectual property prevents being
open-sourced. however, net results of the whole story i told is that i
can't commit and contribute even to the code that was open-sourced
based on my work. so, anyway, what i'm saying is that your case is not
precedent for V4L and so even for my case if some of the parties
decides i guess have grounds for that and can take legal actions, but
that didn't stop anyone and the code to be submitted to V4L.

best regards,
konstantin

Hi,

I've asked Danny to confirm his identity. The @googlemail.com e-mail 
transcript was quite empty :-(

According to Skype he is located in the GB. That's all I've got.

Hope this matter will resolve soon.

Hello Hans,

I am the original author of sit2 source code based on the reference code from silabs.
And we have signed NDA with silabs, it does not allow us to release the source code to the public.
I donot know it is permited or not when you do decompiling the binary code.

What happened between Konstantin Dimitrov and me, I think there is something misunderstand before.
But it looks it is not simple thing as I know he works for the competitor company.
I have some respect before, but now I think he is ridiculous and hostile.
As soon s his rumor release, we know our products really beat him.
What I want to tell him, please improve your products and make them stable.
The rumor just hurt him, not us. 
The customer start to do not believe him as they know the truth someday.

Finally, I have no relationship with Danny Griegs. He does not work for us and pay nothing to him.

Thank you Max for clearing this up a bit,

I can tell you that the decompiled driver works like expected with the 
product I bought and lets me use this product under FreeBSD like I was 
expecting after reading the Linux-commercial's from the Vendor.

Maybe an idea for the future. Abstract binaries a bit more so that they 
are independent of the Linux header files and other kernel functions. 
Then I wouldn't have to do the decompile.

The other DVB-T adapter I had before outputted somtimes corrupted or too 
long USB packets on the isochronous endpoint when the bitrate was going 
too high. I do no longer see this problem with the adapter supported by 
Max's driver. And I am satisfied. Regarding you and "Konstantin 
Dimitrov" I don't want to have any opinion about what product is best.

Hi Antti,

thanks for that information.
The only real new information for me is the 16.000MHz xtal value.

Sad to know that the other chips are hidden.
I assigned more i2c addresses to functions, but not yet all (no idea if 
more addresses are real, or bad interpretations of snooped data).

I now try to check what already works:
- This is video via composite input.
- Next is to try video via analog input - see I see if the tuner in 
general works in this device.

In parallel I try to capture usb in different setups.
1. kvm+tcpdump (using usbmon)
2. usbsnoop on windows vista

Only setup 1 does provide a real list of usb packets.

Regards
Matthias

Matthias, you likely try to do things too complex :) I am not going to 
comment analog side as I simply has no experience. Missing piece of code 
from the DTV point of view is only si2165 demod driver.

My technique is to make successful tune one channel and take sniffs. 
 From sniffs I generate C-code register writes (and sometimes reads too) 
using scripts. Reading that "C-code" is much more visual and easier than 
looking correct bytes from the raw sniffs. It is essential to find out 
from the sniffs what are tuner register writes, what are demod register 
writes and what are for USB-bridge itself. There may be some other chips 
which are needed to init in order to operate, like in cases I2C bus is 
connected through analog demodulator to digital demodulator.

Usually it is rather trivial to make skeleton driver from the code 
generated from sniffs which just shows that single channel sniffs were 
taken.

I have been looking simple example for "reverse-engineer demodulator 
driver how-to" blog post, but I haven't found suitable device yet. That 
was one device I looked, but I given-up as simplest sniff after parsing 
was over 1MB. Looks like there is multiple firmwares to download and 
also CX231xx usb protocol generates a lot of I/O => not very good 
example for simple how-to.

Take a look of that post to see some practical example about sniffing 
and code generation.

Hi Antti,

my real problem currently is, that I cannot get a good usb dump:
1. In virtual machine (win xp under kvm) it finds one transponder when 
scanning DVB-T, but does not get a picture.
2. On real machine with vista I can tune perfectly, but usb snooping 
does not work (at least not the ones I tried).
3. The only sniffer that seemed to produce enough data on vista was 
usblyzer.
But there is not script to convert the output to usbsnoop format.

Should I install windows xp on real hardware to try usbsnoop there? What 
hw/sw/os are you using?

At least I found out something that is working.
By adding the correct ids to the mceusb driver,
the ir part works correctly and all keys of the remote are correctly 
recognized with the existing Hauppauge keymap.

Matthias

I think demod locks (== means signal is OK and demod streams data), but 
stream got lost somewhere on kvm. I have had similar experiences many 
years back when I tested some virtual machines.

SniffUSB2.0 does not support any newer than XP :/ Thats really bad. We 
have to find out new solution...

There is actually script and it is quite simple. I have got it someone 
when we discussed AF9035 driver earlier. I just sent mail to that person 
and asked if he could share that script.

I use native XP on my laptop and SniffUSB2.0.

Lets wait day or two if we can get that conversion script.

Hi Antti,

You were absolutely right here. Using the USB sniffs from the virtual 
machine, I got a picture. So only the stream seems to get lost.
I did this by using these steps:

* Record data: tcpdump -i usbmon1 -w win-tune.tcpdump
* Start virtual machine and tune

* Convert to usbsniff format: parse_tcpdump_log.pl win-tune.tcpdump
* Run parse_cx231xx.pl on it (so i2c transfers can be seen)
* Format it by my own parse-si2165.py

With this I get code of 4700 i2c sends/receives.
When adding a msleep(1) into my si2165_read function, I get a picture

Nice! Thats very good starting point =) Now start implementing things 
correctly.

* proper I2C routines / register write / read
* firmware download
* demod lock flags (that could be found easily by looking sniffs, it is 
reg(s) that is read very often and almost never written)

In a case of demod most registers has just hard coded values. Only case 
where you will likely see different register values is bandwidth 
settings. Unfortunately it is hard to find without modulator where you 
could test easily all 6/7/8 MHz, sniff and diff. Fortunately though, 8 
MHz is used almost everywhere in the world...

Hi Matthias,

I went through a similar path in the past, using USBLyzer on a
virtualized windows environment, and developed this simple awk script
to adapt the csv output of USBLyzer to usbsnoop format. Hope it helps
:)

Hi pierigno,
thank you.
Yes, your script worked as far as it is possible.
But it turned out, usblyzer does not write the setup packet information 
to csv nor to xml output.
And only seeing it in the gui is not helpful for a few thousand register 
writes.

Hi,

>It is DVB-S driver. HVR-900 is DVB-T and DVB-C.
The si2168 is a DVB-T2, DVB-T, and DVB-C demodulator http://www.silabs.com/Support%20Documents/TechnicalDocs/Si2168-A20-short.pdf.

I tried to apply the dvbsky-linux-3.9-hps-v2.diff to media_build.git (used do_patches.sh from http://www.selasky.org/hans_petter/distfiles/webcamd-3.10.0.7.tar.bz2), but I was not able to compile it. I already changed some includes, but then I got the next error.
I just wanted to test if the si2168 module will work with si2165, but as I don't expect it to work I stopped trying to compile the si2168.

Hi,

You need to replace the "media_tree" with a symbolic link to a real 
media_tree. Then it will work! The sources provided with webcamd are 
simply minimal.

There is a file called "sources.txt":

Media tree sources used:
========================

git clone git://linuxtv.org/media_tree.git
git checkout remotes/origin/master

top commit dfb9f94e8e5e7f73c8e2bcb7d4fb1de57e7c333d


Else you could install FreeBSD in VirtualBox or something like that and 
test.

Package is here:

I looked wrong place and driver =)

That driver is asked few times already, nice!

+    History:
+	Max Nibble wrote the initial code, but only released it in
+	binary form. Assembly to C conversion done by HP Selasky.
+	Some possible endian issues fixed.


It is big possibility same DVB-T/C/T2 blocks are used with different 
chips as none wants to reinvent the wheel. That has happened many times.

I wonder is there any change to start mainlining that driver as it is 
converted from the binary? Make documentation and then write clean driver?

I don't see a si2165 driver in the tarball.

Did I miss something?
