Hi Daniel,

Thanks for starting this investigation! If I'm understanding
correctly, there is some work to do, but it can be done and is not a
huge amount of work. (But it is more than just moving something from
the old repo and fixing some errors/warnings.)

I'm not familiar with the linux-media way of organizing the work, or
how priorities are set (on the backlog?). What should be the next step
and what can I do to have this feature/enhancement picked up? I'm not
a developer, but I own the hardware and thus I am able to test any new
code. If there might anything else I can do, please let me know.

Thanks,

Martin

Of course, here it is:

 Say N here, except if you will be fixing the drivers
 compilation.

menuconfig STAGING_MEDIA

I cloned the latest repository and build it, all went fine, however.. (read on)

The ddbridge and cxd2099 are in the latest media_build, but the

Cine CT V6.1 code change request

[Martin Herrman]

All,

I have a Cine CT V6.1 in my fedora 25 based media center. It is now
running a default fedora 4.9 kernel. I install the driver as follows:

hg clone https://linuxtv.org/hg/~endriss/media_build_experimental
cd media_build_experimental
make download
make untar
make menuconfig
make
make install

However, I have to make two changes to the source to make it work.

Change 1: in media_build_experimental/v4l/Kconfig line 6936 I have to
remove the whitespace in '--- help ---', otherwise make menuconfig
fails.
Change 2: during compilation the following error occurs (since about
kernel 4.5?):

make -C /lib/modules/4.9.7-201.fc25.x86_64/build
SUBDIRS=/home/htpc/Downloads/media_build_experimental/v4l  modules

make[1]: Leaving directory '/home/htpc/Downloads/media_build_experimental/v4l'
Makefile:28: recipe for target 'all' failed
make: *** [all] Error 2

Which I fix by commenting out lines 1462 up to 1468 in
media_build_experimental/v4l/compat.h:

//static inline void *
//pci_zalloc_consistent(struct pci_dev *hwdev, size_t size,
// dma_addr_t *dma_handle)
//{
// return dma_alloc_coherent(hwdev == NULL ? NULL : >dev,
// size, dma_handle, GFP_ATOMIC | __GFP_ZERO);
//}

Now it compiles and works fine. I still get these warnings:

media_build_experimental/v4l/compat.h:1552:0: warning:
"DMA_ATTR_SKIP_CPU_SYNC" redefined
 #define DMA_ATTR_SKIP_CPU_SYNC 0

Which I can easily remove by commenting out the specific line as well.

Now my questions are:
- is this the correct way to fix these compile errors? (I'm definately
not a professional developer)
- what can I do to have this solved in the source?

Besides that, I'm also wondering if these drivers have any change of
getting into kernel mainline?

Regards,

Martin

Re: ddbridge module fails to load

[Martin Herrman]

2013/11/18 Oliver Schinagl oliver+l...@schinagl.nl:

Hi Olivier S.,

 You probably best poke Oliver Endriss (ufo) on the VDR portal as that is his
 work and is unrelated or unmaintained here at linux-media.

thanks for the tip, I have found the german VDR portal and will do so.

 That said, someone recently stepped up to try to bring in the latest driver
 back into the mailine linux-media repository and should get better
 maintenance.

That is very good news, it makes my life much easier :-)

Regards,

Martin

ddbridge module fails to load

[Martin Herrman]

Hi,

Since about a year I'm a happy user of the experimental driver for my
cine c2 v6.

I have just tried to use the latest code. It compiles without issues
(kernel 3.11 with gentoo and ck patches), but doesn't load:

ddbridge: Unknown symbol dvb_usercopy (err 0)

I reviewed the updates:

http://linuxtv.org/hg/~endriss/media_build_experimental

and noticed that there have been updates to the drivers I use lately.
Which is good news!

Unfortunately, the updates cause the above issue. I tried this revision:

http://linuxtv.org/hg/~endriss/media_build_experimental/rev/8c5bb9101f84

and now ddbridge loads perfectly and I can watch tv again.

Just wanted to let you know, in case you need any of my help to fix
this, please feel free to ask.  Note however that I'm certainly not a
developer, nor a experienced packager.

Regards,

Martin

 No, the drivers I need were already there but I just checked my

 Is that what you're looking for? If so, all you need, I think, is DVB

 get the Customize TV tuners option.

 Thanks for the input, but that's not the driver I need. I need the
 ddbridge compatible (?) driver, NXP TDA18212 DD

 [*] DVB/ATSC adapters
 M Digital Devices bridge support
 [*] Customse the frontend modules to build
 Customize DVB Frontends →
 STV 0367 (DD)
 NXP TDA18212 silicon tuner (DD)

Problem solved: although I cannot select the drivers, they are build
during 'make'. Done a make install and reboot and card is detected :-)

Re: Make menuconfig doesn't work anymore

[Martin Herrman]

2012/7/11 VDR User user@gmail.com:

 Actually I got the exact same error when compiling a new 3.4.4 kernel.

It always feels good to know that you're not alone ;-)

 I assume the api_version.patch is bad or needs to be updated. I simple
 just commented out the add api_version.patch line in
 backports/backports.txt and crossed my fingers the drivers I use still
 worked -- which they did so all is well here (afaik). But, yeah it
 does need a proper fix and I only recommend my cheap workaround with a
 YMMV warning.

thanks, this solved the first part of the problem. I can now do a make
menuconfig, but the frontend modules I need cannot be selected,
although the file
/usr/src/media_build_experimental/linux/drivers/media/dvb/frontends/tda18212dd.c
etc. do exist.

I have also looked into the staging drivers and enabled drivers not
supported by this kernel, but stil no luck.

Did you have this problem as well?

Make menuconfig doesn't work anymore

[Martin Herrman]

All,

I own a Cine CT v6 and compiled drivers for it succesfully using:
-  hg clone http://linuxtv.org/hg/~endriss/media_build_experimental
- cd media_build_experimental
- make download
- make untar
- make menuconfig (only select drivers I need)
- make install
- reboot

This worked succesfully on Ubuntu 11.10, Ubuntu 12.04 and on Gentoo
Linux. After another fresh install of Gentoo Linux (just a couple of
days after the previous one - now with custom compiled kernel), it
doesn't work anymore. The make menuconfig command fails:

Make menuconfig *does* work when configuring a new kernel. I have also
tried with kernel 3.2.22 and 3.4, but no succes either.

Any ideas what is going wrong?

Thanks in advance!

Note that I'm running latest stable Ubuntu 64-bit with kernel 3.0.0-16-generic.

First I tried the drivers from
http://linuxtv.org/hg/~endriss/media_build_experimental/. In that
case, dmesg output is:

[   11.728370] WARNING: You are using an experimental version of the

[   11.728372]  As the driver is backported to an older kernel, it doesn't offer

So I started to try the build instructions found here:

http://linuxtv.org/wiki/index.php/How_to_Obtain,_Build_and_Install_V4L-DVB_Device_Drivers

And after compile, install and a reboot, dmesg output is:

lsmod shows that ddbridge and dvb_core are loaded. /dev/ddbrigde/card0

entries exist for the tv-tuner card.

I can manually load cxd2820r, which loads succesfully

Re: [DVB Digital Devices Cine CT V6] status support

2012/1/9 Thomas Kaiser linux-...@kaiser-linux.li:

 Hello Martin

 I use the DD Cine CT V6 with DVB-C. It works without problems.
 I got the driver before Oliver integrated it in his tree. Therefor I did not
 compile Olivers tree, yet.

 At the moment I run the card on Ubuntu 11.10 with kernel 3.0.0-14.

 Hope this helps.

 Thomas

Hi Thomas,

that is very good news, thanks a lot for the confirmation. Time to
order one myself!

Regards,

Martin

 The short answer is yes, and as far as I know, it's working fine with DVB-T
 (I've never tested the DVB-C).
 For support, you need to compile the drivers from Oliver Endriss as they are
 not merged in mainstream kernel.

 Check here (kernel  2.6.31):
 http://linuxtv.org/hg/~endriss/media_build_experimental/
 Or here (kernel  2.6.36) :
 http://linuxtv.org/hg/~endriss/ngene-octopus-test/

Hi Sébastien,

thanks for your quick and positive reply.

Anyone here that tested it with DVB-C?

Are there any plans to merge this in the mainstream kernel?

Regards,

Martin

[DVB Digital Devices Cine CT V6] status support

[Martin Herrman]

Dear list-members,

I'm building a HTPC based on Linux and searching for an DVB-C tuner card that:
- fits the mobo (only pci-e/usb available, not pci or firewire)
- fits the case (antec fusion remote, big enough)
- is supported by linux
- is dual tuner
- supports encrypted HD content
- provides good quality

digital devices cine ct v6 seems to be a perfect solution, together
with a softcam based on smargo cartreader.

http://shop.digital-devices.de/epages/62357162.sf/en_GB/?ObjectPath=/Shops/62357162/Categories/HDTV_Karten_fuer_Mediacenter/Cine_PCIe_Serie/DVBC_T

But.. is this card supported by the Linux kernel?

In 3.2.0-rc7 kernel I have found the driver for most of the digital
devices cards, which includes the Cine S2 v6, but not the Cine CT v6.
(I have also found some experimental drivers for CI moduels in the
staging drivers section).

On the other hand, this discussion seems to indicate that drivers for
Cine CT v6 should be working at this time:

http://www.mail-archive.com/linux-media@vger.kernel.org/msg37183.html

Can you give me an update on the status of a possibly existing driver
for Cine CT v6?

Much thanks in advance,

Martin
