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]])


High bandwidth transponders (>45Mbps) are problematic, eg 23.5E 12207 V 27500 5/6.
The patch can be extracted from the file and applied directly to the mainline linux source. Works pretty well then.


==Page Allocation Failure==
No support for 8PSK 3/4. To support the need to replace the crystal oscillator of 45 MHz to 66,667 MHz


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
With the latest patch / driver everything is working fine. Also for 8PSK 3/4 no hardware upgrade is needed.

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
