The [[CX24118A]] Tuner supports QPSK, 8PSK Modulation.

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.
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]])

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

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

[Update 2014/04/22]

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

The driver from Custler with latest adaption for 3.10 - 3.13 by Ducky ([[http://www.vdr-portal.de/index.php?page=Thread&postID=1163233#post1163233]])

==Compiling on Debian==

Modify as root /etc/sources.list, adding non-free and backports:
deb http://ftp.es.debian.org/debian/ wheezy main non-free
deb-src http://ftp.es.debian.org/debian/ wheezy main non-free
deb http://ftp.es.debian.org/debian/ wheezy-backports main
deb-src http://ftp.es.debian.org/debian/ wheezy-backports main

Install (as root) last kernel and firmwares

apt-get update
apt-get install firmware-linux
apt-get install linux-image-3.14-0.bpo.1-686-pae
reboot

As regular user, download sources for the installed kernel

mkdir src
cd src
apt-get source linux-image-3.14-0.bpo.1-686-pae

Make a symlink to help next patching

ln -s linux-3.14.4/ linux

Copy the patch 31_S2_CX24120_SYS_DVBS.patch to the current path and apply it
patch -p1 < 31_S2_CX24120_SYS_DVBS.patch

Get into the directory with the kernel source

cd linux

Configure and compile. You have two choices
1) Only needed kernel-modules
make oldconfig
make SUBDIRS=drivers/media modules


==Page Allocation Failure==
2) All the kernel. Take a coffee...
make oldconfig
make


Some systems see occasional page allocation problems on module reload/init (even on systems with 1GB of ram). The following command may help:
Backup the old modules for the card (just in case...)
cp /lib/modules/3.14-0.bpo.1-686-pae/kernel/drivers/media/common/b2c2/b2c2-flexcop.ko /lib/modules/3.14-0.bpo.1-686-pae/kernel/drivers/media/common/b2c2/b2c2-flexcop.ko.bak
cp /lib/modules/3.14-0.bpo.1-686-pae/kernel/drivers/media/pci/b2c2/b2c2-flexcop-pci.ko /lib/modules/3.14-0.bpo.1-686-pae/kernel/drivers/media/pci/b2c2/b2c2-flexcop-pci.ko.bak


echo 16384 > /proc/sys/vm/min_free_kbytes
Copy your recently-compiled modules to the correct path
cd drivers/media/
cp pci/b2c2/b2c2-flexcop-pci.ko /lib/modules/3.14-0.bpo.1-686-pae/kernel/drivers/media/pci/b2c2/b2c2-flexcop-pci.ko
cp common/b2c2/b2c2-flexcop.ko /lib/modules/3.14-0.bpo.1-686-pae/kernel/drivers/media/common/b2c2/b2c2-flexcop.ko
cp dvb-frontends/cx24120.ko /lib/modules/3.14-0.bpo.1-686-pae/kernel/drivers/media/dvb-frontends/

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
