[gentoo-user] cx23885 (DVBSky 950) under Gentoo 4.0.5

[Tamer Higazi]

Hi people!
I do have a DVBSky S950 (PCI Express) in my gentoo system.
The poducer of this board told me that the kernel module is: cx23885
which I don't find. Can somebody help me which modules to load ?!

Where do I find those when I compile the kernel ?

04:00.0 Multimedia video controller: Conexant Systems, Inc. CX23885 PCI
Video and Audio Decoder (rev 04)
	Subsystem: DVBSky S950
	Flags: bus master, fast devsel, latency 0, IRQ 18
	Memory at fe800000 (64-bit, non-prefetchable) [size=2M]
	Capabilities: [40] Express Endpoint, MSI 00
	Capabilities: [80] Power Management version 2
	Capabilities: [90] Vital Product Data
	Capabilities: [a0] MSI: Enable- Count=1/1 Maskable- 64bit+
	Capabilities: [100] Advanced Error Reporting
	Capabilities: [200] Virtual Channel



Thanks, best Tamer

Those cx23885 based DVB cards by DVBSky or Mystique (both are
identically) need a ClosedSource driver. The DVB chip is a cx23885. The
driver for those chips is meanwhile principally included in the kernel
but doesn't work, because it needs a ClosedSource module called sit2
which is not included in the kernel.

I once bought such a DVB-C card by DVBSky, but wasn't able to install
the driver and get it running, neither from the kernel nor from
media-build-bst on the manufacturer's website which includes this sit2
module.

Their support (the manufacturer's and the retailer's) wasn't able to or
didn't want to help me. In a lot of e-mails they more or less only
repeated the installation instructions in their README which don't work.

In the end I returned that card and bought one with an saa7146 chip
which is indeed fully OpenSource and included in the kernel. That said
this card doesn't work very well, too.

I have neither cards, but can see there are DVBSky 950 drivers, firmware and 
kernel patches here:

Hi people!

I have upgraded to the latest kernel 4.2.0 and selected all PCI boards
As option to choose which frontent, I selected automatic selection.

I restarted now and it all runs the way I want.

I have previously copied the firmware from dvbsky in /lib/firmware and
restarted the machine.

The board is displayed propperly and it's listed in the /dev/dvb folder:

tamer@tux ~ $ ls -lA /dev/dvb/adapter0/
insgesamt 0
crw-rw---- 1 root video 212, 1 27. Okt 00:12 demux0
crw-rw---- 1 root video 212, 2 27. Okt 00:12 dvr0
crw-rw---- 1 root video 212, 0 27. Okt 00:12 frontend0
crw-rw---- 1 root video 212, 3 27. Okt 00:12 net0


before I got to bed I recompile glibc, gcc x 2times and built the gentoo
kernel once again.


best, Tamer

I know those websites, and this driver didn't compile for me
particularly not following this How to.

Maybe they finally fixed this driver. It's a while ago that I tried
this. Btw., I did the same as you did, but of course with an older
kernel version. Or the sit2 module is only needed for the DVB-C and not
for the DVB-S cards.

Dear Heiko,

Thank you still for your support. Do you have any idea to get the
"scan-s2" application compiled, that I am capable to scan here in
Germany DVB-S2 channels.... and to have as result the "channels.conf" ?!


I am looking forward to hearing from you.



best, Tamer

Unfortunately I don't. I have a DVB-C card so I can't say much about
DVB-S2. But I'm not sure if the dvb-apps, scan and dvbscan, have worked
for me.

If I recall correctly I used w_scan which supports DVB-S2, too,
according to its man page. It's in the portage tree.
