Why build it externally? I was quite certain that the ddbridge
drivers are in mainline for a while now?
Which modules to you select?
ddbridge is upstream with DVB-S2 support, but not the driver for my
C/T-module.
What C/T driver module are you using?
I do have a Terratec DVB-T dual (which does dvb-c too on 1 of the dual
tuners) which features the drxk demodulator. So I think your card should
be quite supported in mainline already.
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=blob_plain;f=drivers/media/pci/ngene/ngene-cards.c;hb=HEAD
even lists: \/ so unless I go digging into the linux-media code, I think
even dvb-CT support has been mainlined :)
static int port_has_drxk(struct i2c_adapter *i2c, int port)
{
u8 val;
if (i2c_read(i2c, 0x29+port, &val) < 0)
return 0;
return 1;
}
static int demod_attach_drxk(struct ngene_channel *chan,
struct i2c_adapter *i2c)
{
struct drxk_config config;
memset(&config, 0, sizeof(config));
config.microcode_name = "drxk_a3.mc";
config.qam_demod_parameter_count = 4;
config.adr = 0x29 + (chan->number ^ 2);
chan->fe = dvb_attach(drxk_attach, &config, i2c);
if (!chan->fe) {
printk(KERN_ERR "No DRXK found!\n");
return -ENODEV;
}
chan->fe->sec_priv = chan;
chan->gate_ctrl = chan->fe->ops.i2c_gate_ctrl;
chan->fe->ops.i2c_gate_ctrl = drxk_gate_ctrl;
return 0;
}
Ah! that explains a lot. I did a quick read through that german site,
but they simply pull the latest media-linux git tree, so that should go
into mainline every cycle or so I guess.
Nevertheless, good to know that DVB-S2 on the ngene is well supported (I
guess ) :)

I'm thinking of getting into the whole satellite thing (DVB-T user
for now) and was searching for interesting DVB-S2
tuners. I found that the l4m octopus/duoflex-s2 a very interesting
device. While expensive you can connect up to 8
tuners! to a single PCI-e 1x lane (Bandwith should be more then
enough). While I know there is a octopus mini-pcie
device, I heard that there where some PCB issues so decided on
getting the PCI-e version.
I have tried googling for some up to date linux! information but
found very little. Are there any l4m/dd octopus/duoflex
DVB-S2 (or even CAM/DVB-C/DVB-T) users here that can share their
current (and past) experiences? The tuner (only 1
dualtuner board and the octopus) will set you back a good 200Euro
so I want to be sure that the devices is properly
supported.
I'm using a DuoFlex with a DVB-C/T dual tuner modul. How to build
the latest drivers is described here (german only):
http://www.vdr-portal.de/board16-video-disk-recorder/board85-hdtv-dvb-s2/113367-aktuelle-treiber-f%C3%BCr-octopus-ddbridge-cines2-ngene-ddbridge-duoflex-s2-duoflex-ct-cinect-sowie-tt-s2-6400-teil-2/
If you'r using Ubuntu or yaVDR, there's the linux-media-dkms
package with this driver included.
My DVB-C/T card is working here for months with no problems.
Second dual tuner is ordered... :)
Lars.
