I apologize sincerely; I shouldn't have missed it before sending you
the pull request. (stupid copy-paste across files is certainly no
excuse for this).

This got caught in for-next too, but right after I sent the pull-request :(.

I also shouldn't have sent it so late in the merge cycle - this could
certainly wait till -rc2, which would've helped me correct it before
the request to you. Serves me right to try and meet the merge-cycle
deadline in a jet-lagged state!

I will definitely take extra precautions next time onward, so you
don't see negligence like this in my requests to you.

Apologies again!

Mygica T230 DVB-T/T2/C Ubuntu 14.04 (kernel 3.13.0-45) using media_build

Can someone help me to get a Mygica T230 DVB-T/T2/C working on Ubuntu 14.04

I succeed doing a build of the media_build, the drivers also load when I

Re: Linux TV support Elgato EyeTV hybrid

2015-02-22 Thread Gilles Risch 

Hi,

most of the used components are identified:
- USB Controller: Empia EM2884
- Stereo A/V Decoder: Micronas AVF 49x0B
- Hybrid Channel Decoder: Micronas DRX-K DRX3926K:A3 0.9.0
The only ambiguity is the tuner, but I think it could be a Xceive XC5000 
because the windows driver comprises the xc5000 firmware and it is 100% 
identical:

$ mkdir extract-xc5000-fw
$ cd extract-xc5000-fw
$ wget http://linuxtv.org/downloads/firmware/dvb-fe-xc5000-1.6.114.fw
$ wget 
http://elgatoweb.s3.amazonaws.com/Documents/Support/EyeTV_Hybrid/EyeTV_Hybrid_2008_509081301_W8.exe

$ 7z -y e EyeTV_Hybrid_2008_509081301_W8.exe
$ dd if=emBDA.sys of=dvb-fe-xc5000-test.fw bs=1 skip=518800 
count=12401 >/dev/null 2>&1

$ md5sum dvb-fe-xc5000-1.6.114.fw dvb-fe-xc5000-test.fw
b1ac8f759020523ebaaeff3fdf4789ed  dvb-fe-xc5000-1.6.114.fw
b1ac8f759020523ebaaeff3fdf4789ed  dvb-fe-xc5000-test.fw

The Elgato_EyeTV_Hybrid.inf file contains a comment with "TerraTec H5", 
which components are assembled on that USB stick?

Gilles

Hi Gilles,

Not sure if the following information will help you, but here comes.
The USB bridge is EM2884, supported by em28xx driver. The Micronas
demodulator is probably supported by drxk driver. Tuner I did not
recognize after a quick glimpse. That sandwich construction look like
something PCTV has used with some of their designs (290e and 292e for
example).

In order to have a driver for your device you need to have each
individual component supported (USB bridge, demod and tuner). Then
these can be combined into a driver (typically by modifying the USB
bridge driver).

Cheers,

Hello,

I'm owning an Elgato EyeTV hybrid USB stick that I'm using daily on my
iMac, now I'd like to use it on my laptop too but I'm unable to get it
running. Is this device already supported? If not, is there any way I
can help? I've already opened my device and uploaded the photos to the
linux TV wiki page
(http://www.linuxtv.org/wiki/index.php/Elgato_EyeTV_hybrid).
I'm not sure which tuner is mounted on the PCB, therefor I've made two
USB traces, maybe someone could interpret them and conclude which one
is used:

Re: DVB Simulcrypt

2015-02-22 Thread Rudy Zijlstra 

Some more info

On 21-02-15 22:30, Rudy Zijlstra wrote:

Dears (Hans?)

My setup, where the cable operator was using only irdeto, was working 
good. Then the cable operator merged with another, and now the 
networks are being merged. As a result, the encryption has moved from 
irdeto only to simulcyrpt with Irdeto and Nagra.


Current status:
- when i put the CA card in a STB, it works
- when trying to record an encrypted channel from PC, it no longer works.
Recording system has 3 tuners. All equal, all with same permissions on 
the smartcard. On cards 0 and 2 does not work, but card 1 does work, on 
all channels tested.




I suspect the problem is that the wrong keys are used: Nagra keys in 
stead of Irdeto keys.


I do not know whether:
- kernel issue (is simulcrypt supported?)
- API issue (is all support in place to select the right key stream?)
- application issue (does the application allow to set the right CA?)

If this is an application issue, could it be solved by setting the API 
outside the application, to direct it to the right (Irdeto in my case) 
encryption?


The application i am using is MythTV.


Cheers

[PATCH 10/10] [media] siano: register media controller earlier

2015-02-22 Thread Mauro Carvalho Chehab 
We need to initialize the media controller earlier, as the core
will call the smsdvb hotplug during register time. Ok, this is
an async operation, so, when the module is not loaded, the media
controller works.

However, if the module is already loaded, nothing will be
registered at the media controller, as it will load too late.

[PATCH 00/10] siano: add media controller and use pr_foo()

2015-02-22 Thread Mauro Carvalho Chehab 
The first patch adds media controller support. It is a rebased
version of a previously sent patch, plus the logic to unregister
the media controller device.

The next 8 patches convert siano to pr_foo() and removes the
now obsolete sms_dbg parameter.

The last patch fixes an issue on initializing the media controller
entities that happens when the device is removed and re-inserted.

Mauro Carvalho Chehab (10):
  [media] siano: add support for the media controller at USB driver
  [media] siano: use pr_* print functions
  [media] siano: replace sms_warn() by pr_warn()
  [media] siano: replace sms_err by pr_err
  [media] siano: replace sms_log() by pr_debug()
  [media] siano: replace sms_debug() by pr_debug()
  [media] siano: get rid of sms_info()
  [media] siano: get rid of sms_dbg parameter
  [media] siano: print a message if DVB register succeeds
  [media] siano: register media controller earlier

[PATCH 03/10] [media] siano: replace sms_warn() by pr_warn()

2015-02-22 Thread Mauro Carvalho Chehab 
There's no reason for a sms' own sms_warn macro. Just replace
it by the standard pr_warn().

[PATCH 01/10] [media] siano: add support for the media controller at USB driver

2015-02-22 Thread Mauro Carvalho Chehab 
Adding support for the media controller for a pure DVB device
is simple: just create a struct media_device and add it to the
dvb adapter. After creating all DVB devices, we need to call
the DVB core, for it to create the media graph.

More work is needed for pure DVB tuners, but this is hidden
at the Siano driver, just like several others non-hybrid
devices. So, this is streight forward.

Originally, sms_err() would be also displaying the line where
the error occurs, but the messages are clear enough. Also,
the function is always printed. So, no need for it.

[PATCH 02/10] [media] siano: use pr_* print functions

2015-02-22 Thread Mauro Carvalho Chehab 
Instead of defining its own set of printk functions, let's
use the common Kernel debug logic provided by pr_foo functions.

As a first step, let's just define the existing macros as the
Kernel ones.

[PATCH 08/10] [media] siano: get rid of sms_dbg parameter

2015-02-22 Thread Mauro Carvalho Chehab 
All siano modules have a sms_dbg parameter. Now that we're using
the standard pr_debug() macro, we can get rid of it.

which components are assembled on that USB stick?


The TerraTec H5 has a TDA18271 tuner.

So most likely the Elgato EyeTV hybrid is one of these combinations. And 
it should quite feasible to add support for someone who knows the Empia 
EM2884.

That device could be supported just making proper board profile to 
em28xx driver. Rather trivial stuff to one who has any experience. Just 
one hour work or so.

That looks weird... I think the patch adding media controller support
for the dvb-usb was not merged yet.


hmm, OK. But I have got at least one such report for rtl28xxu driver on 
my mail and there is another report on my blog, which is likely same, 
though there was no log, only report saying it crash when latest media 
build used.

I succeed doing a build of the media_build, the drivers also load when I
attach the Mygica, but when I try to use it (tvheadend) it crashes:

Gert-Jan,

Could you please post the stack dump? It would help to know what's calling
media_entity_pipeline_start.

Regards,
Mauro



What is wrong, or do I miss something ?
I also added the firmware described at:
