Making it Work

The card is working under Linux using the Mantis driver. Kernel support is available since Kernel version 2.6.33. For kernel versions prior to 2.6.33, see the corresponding sections under Drivers below.

Firmware

No firmware required.

Drivers

Kernel Driver

The Mantis Driver is part of the vanilla linux kernel[2] since 2.6.33.

S2API Driver for Kernel Versions <= 2.6.33

Install the latest mantis drivers:

sudo apt-get install mercurial linux-headers-$(uname -r) build-essential
hg clone http://mercurial.intuxication.org/hg/s2-liplianin
cd s2-liplianin
make
sudo make install
sudo reboot

If you have a distribution which uses DKMS (like Ubuntu), Mantis with DKMS is a convenient way to install the driver and keep it running for new kernel releases.

There have been some problems with the s2-liplianin repository (only works for 30 minutes) and a fix that has worked for someone is to use http://jusst.de/hg/v4l-dvb instead of http://mercurial.intuxication.org/hg/s2-liplianin. You should/could also use the sudo make menuconfig and remove all the unnecessary modules.

Old Multiproto Driver

Old mantis-multiproto (obsolete API) repository instructions. Won't compile with latest kernels, if in doubt, try the vanilla kernel module or the S2API instructions above.

cd /usr/src
sudo apt-get install mercurial
sudo hg clone http://jusst.de/hg/mantis  
cd mantis
sudo make
sudo make install
sudo reboot

Remote Control Support

Supported under the vanilla kernel module.

Works for the old mantis multiproto driver after applying the following patch. See [3]

CI support

CI/CAM support for the optional CI module is not working yet (27.11.2024)

Known Issues

Working around i2c bus probing interference with ivtv

If the mantis module won't load (hangs) with the error message

mantis_ack_wait (0): Slave RACK Fail !

you should check [[4]]

TDA10023(0): tda10023_writereg, writereg error (reg == 0x08, val == 0x23, ret == -121)

---

femon output is not correct (statistics aren't implemented correctly in the driver)

card seems to be unreliable with other devices at some point, better do some more research about a better supported PCI device rather than this one.
