==Drivers==
Binary driver (non-GPL) available here: http://www.technisat-daun.de/download/soft/soft_linux-driver_12-2008_6611.zip


The [[CX24118A]] Tuner supports QPSK, 8PSK Modulation.
There is a patch for the s2-liplianin driver that adds support for the SkyStar S2. Instructions (german) can be found here: http://vdr-portal.de/board/thread.php?threadid=97096#post951944


== Drivers ==
The patch can be extracted from the file and applied directly to the mainline linux source. Works pretty well then.


Driver now in the main media tree, should be included in 4.2 kernel. Can be installed before then with the V4L-DVB media_build process: [[How_to_Obtain,_Build_and_Install_V4L-DVB_Device_Drivers]]. Requires firmware file dvb-fe-cx24120-1.20.58.2.fw.
No support for 8PSK 3/4. To support the need to replace the crystal oscillator of 45 MHz to 66,667 MHz


High bandwidth transponders (>45Mbps) are problematic, eg 23.5E 12207 V 27500 5/6.


==Page Allocation Failure==

Some systems see occasional page allocation problems on module reload/init (even on systems with 1GB of ram). The following command may help:

echo 16384 > /proc/sys/vm/min_free_kbytes

TechniSat SkyStar S2 Card

A FTA PCI DVB-S2 card from TechniSat.

Components Used

The CX24118A Tuner supports QPSK, 8PSK Modulation.

Drivers

Driver now in the main media tree, should be included in 4.2 kernel. Can be installed before then with the V4L-DVB media_build process: How_to_Obtain,_Build_and_Install_V4L-DVB_Device_Drivers. Requires firmware file dvb-fe-cx24120-1.20.58.2.fw.

High bandwidth transponders (>45Mbps) are problematic, eg 23.5E 12207 V 27500 5/6.

Page Allocation Failure

Some systems see occasional page allocation problems on module reload/init (even on systems with 1GB of ram). The following command may help:

echo 16384 > /proc/sys/vm/min_free_kbytes
