[linux-dvb] Elgato EyeTV Diversity patch

[linux-dvb] Elgato EyeTV Diversity patch

Hi,

this week I bought a Elgato EyeTV Diversity USB stick for my iBook
that I also wanted to use with my Linux system. I thought it is a good
choice because the Supported Hardware list states for the Hauppauge
Nova-T stick that it's 'Identical to the USB Stick Elgato is
selling'. But mine has a different vendor and product id.

Simply adding a new entry beside the Hauppauge Nova-T stick using the
new ids didn't work. Using trail and error I was able to find the
right combination. I also was able to activate the remote
control. Since the other devices that use stk7070pd_frontend_attach0
and stk7070pd_frontend_attach1 as frontends doesn't activate the RC I
needed to start a section for my stick. If it doesn't hurt the other
devices to have a RC defined perhaps you should combine them.

The patches are based on the v4l-dvb code I got on Saturday using hg
clone http://linuxtv.org/hg/v4l-dvb. I have a 2.6.25 kernel. Would it
help to check if these patches works against the vanilla 2.6.25 too?

Here are some results/comments/questions:

This is what I get now:

What about these i2c errors? Should I worry about them? Although if
not do you have an idea how I can get rid of them?  'i2c-adapter
i2c-2: SMBus Quick command not supported, can't probe for chips'

To use the remote control you have to set the module parameter
dvb_usb_dib0700_ir_proto=0 (NEC). Is there a possibility to hard-code
this in the driver? The standard protocol RC5 worked somehow, i.e. I
got reproducable numbers, but from time to time I got wrong numbers
and there was no system in the created numbers. With NEC protocol the
first number is always 0x45 and the second number is more or less a
simply serially numbered value starting with 1. So I would assume that
they really use NEC protocol which should be a parameter of the device
description in the code so that the driver uses the right setting by
default.

It works with both firmware versions: dvb-usb-dib0700-1.10.fw and
dvb-usb-dib0700-1.20.fw. I use a link for the 1.20 so that I don't
need to need to change the code.

Although it is stated that the diversity mode is currentl not
supported it seems to be necessary that both antenna plugs are
connected. I have an active antenna and I thought that without
diversity it would be the best to connect the antenna directly to the
adapter that I want to use. But in this combination 'scan' only
creates 'WARNING: >>> tuning failed!!!' messages. If I use the Y-cable
to connect the antenna to both adapters scan is able to find the TV
channels. Do you have an explanation for this behaviour?

Are there plans to add support for the diversity mode?

It maked my work to get the device running smooth that I was able to
work in a private v4l-dvb directory without the need to patch the
kernel sources and simply call 'make && make install' for the changed
modules in this private directory.

Regards

Michael

Not a worry.  If you see, they concern different devices
(`lsusb' will show you what they are) on the USB bus...

Yes, please do that. And send the patch again with your Signed-off-by-line 
and both file-changes created with hg diff of the v4l-dvb repository.

As you might have noticed, pluging the hardware results in having two 
/dev/dvb/adapters. Diversity is in fact disabled, but dual-mode (sometimes 
referred as PVR) is activated by default.

Diversity actually is the combination of the signal resulting from two 
different antennas (and tuners and demodulators). This is not yet 
supported by LinuxTV-drivers.

> Are there plans to add support for the diversity mode?

Yes.

Thanks for your patch,
Patrick.

I'll do that.

It will be the first time for me. ;-)

Yes, but scan uses adapter0 frontend0 by default. So why does it  
makes failing to scan adapter0 if the antenna is not connected to  
adapter1?

Any timeline?

Need help?

Sorry for the delay but I was busy the last two weeks.

I have the patch now ready but some tests show me that the RC part  
does not work fully as expected: After hitting a key on the remote  
control it seems that the key is send over and over again. If I hit  
another key it switches to this key and keeps sending this key. This  
problem already shows in a command line window. It seems to be a  
driver problem because if I activate the outcommented info() command  
in the driver I get the same output over and over.

Do you have an idea what's going wrong?

If not, should I remove the RC support from the patch?

Regards

Michael
