NEWS:
2004-09-13 - added support for a new device (Artec T1 USB TVBOX), thanks
to Christian Motschke for reporting
2004-09-05 - released the dibusb device and dib3000mb-frontend driver
(old news for vp7041.c)
2004-07-15 - found out, by accident, that the device has a TUA6010XS for
frequency generator
2004-07-12 - figured out, that the driver should also work with the
CTS Portable (Chinese Television System)
2004-07-08 - firmware-extraction-2.422-problem solved, driver is now working
properly with firmware extracted from 2.422
- #if for 2.6.4 (dvb), compile issue
- changed firmware handling, see vp7041.txt sec 1.1
2004-07-02 - some tuner modifications, v0.1, cleanups, first public
2004-06-28 - now using the dvb_dmx_swfilter_packets, everything
runs fine now
2004-06-27 - able to watch and switching channels (pre-alpha)
- no section filtering yet
2004-06-06 - first TS received, but kernel oops :/
2004-05-14 - firmware loader is working
2004-05-11 - start writing the driver
1. How to use?
NOTE: This driver was developed using Linux 2.6.6.,
it is working with 2.6.7, 2.6.8.1.
Linux 2.4.x support is not planned, but patches are very welcome.
NOTE: I'm using Debian testing, so the following explaination (especially
the hotplug-path) needn't match your system, but probably it will :).
1.1. Firmware
The USB driver needs to download a firmware to start working.
You can either use "get_dvb_firmware dibusb" to download the firmware or you
can get it directly via
http://linuxtv.org/cgi-bin/cvsweb.cgi/dvb-kernel/firmware/dvb-dibusb-5.0.0.11.fw?rev=1.1&content-type=text/plain
1.2. Compiling
Since the driver is in the linux kernel, activating the driver in
your favorite config-environment should sufficient. I recommend
to compile the driver as module. Hotplug does the rest.
1.3. Loading the drivers
Hotplug is able to load the driver, when it is needed (because you plugged
in the device).
If you want to enable debug output, you have to load the driver manually.
modprobe dvb-dibusb debug=1
modprobe dib3000mb debug=1
should do the trick.
When the driver is loaded successfully, the firmware file was in
the right place and the device is connected, the "Power"-LED should be
turned on.
At this point you should be able to start a dvb-capable application. For myself
I used mplayer, dvbscan, tzap and kaxtv, they are working. Using the device
as a slave device in vdr, was not working for me. Some work has to be done
(patches and comments are very welcome).
2. Known problems and bugs
TODO:
- add some additional URBs for USB data transfer
- due a firmware problem i2c writes during mpeg transfers destroy the stream
no i2c writes during streaming, interrupt streaming, when adding another pid
2.1. Adding new devices
It is not possible to determine the range of devices based on the DiBcom
reference design. This is because the reference design of DiBcom can be sold
to third persons, without telling DiBcom (so done with the Twinhan VP7041 and
the HAMA device).
When you think you have a device like this and the driver does not recognizes it,
please send the ****load.inf and the ****cap.inf of the Windows driver to me.
Sometimes the Vendor or Product ID is identical to the ones of Twinhan, even
though it is not a Twinhan device (e.g. HAMA), then please send me the name
of the device. I will add it to this list in order to make this clear to
others.
If you are familar with C you can also add the VID and PID of the device to
the dvb-dibusb.[hc]-files and create a patch and send it over to me or to
the linux-dvb mailing list, _after_ you have tried compiling and modprobing
it.
2.2. Comments
Patches, comments and suggestions are very very welcome
3. Acknowledgements

to start accessing the card with utilities such as scan, tzap,

The current version of the frontend module sp887x.o, contains
no firmware drivers?, so the first time you open it with a DVB
utility the driver will try to download some initial firmware
to the card. You will need to download this firmware from the
web, or copy it from an installation of the Windows drivers
that probably came with your card, before you can use it.
The default Linux filesystem location for this firmware is
/usr/lib/hotplug/firmware/sc_main.mc .
_________________________________________________________
Getting the Firmware
As the firmware for the card is no longer contained within the
driver, it is necessary to extract it from the windows
drivers.
The Windows drivers for the Avermedia DVB-T can be obtained
from: http://babyurl.com/H3U970 and you can get an application
to extract the firmware from:
http://www.kyz.uklinux.net/cabextract.php.
_________________________________________________________
The frontend module sp887x.o, requires an external firmware.
Please use the command "get_dvb_firmware sp887x" to download
it. Then copy it to /usr/lib/hotplug/firmware.

View file @ 2da8c87f
Some DVB cards and many newer frontends require proprietary,
binary-only firmware.
The DVB drivers will be converted to use the request_firmware()
hotplug interface (see Documentation/firmware_class/).
(CONFIG_FW_LOADER)
The firmware can be loaded automatically via the hotplug manager
or manually with the steps described below.
Currently the drivers still use various different methods
to load their firmwares, so here's just a short list of the
current state:
- dvb-ttpci: driver uses firmware hotplug interface
- ttusb-budget: firmware is compiled in (dvb-ttusb-dspbootcode.h)
- sp887x: firmware is compiled in (sp887x_firm.h)
- alps_tdlb7: firmware is loaded from path specified by
"mcfile" module parameter; the binary must be
extracted from the Windows driver (Sc_main.mc).
- tda1004x: firmware is loaded from path specified in
DVB_TDA1004X_FIRMWARE_FILE kernel config
variable (default /usr/lib/hotplug/firmware/tda1004x.bin); the
firmware binary must be extracted from the windows
driver
- ttusb-dec: see "ttusb-dec.txt" for details
1) Automatic firmware loading
You need to install recent hotplug scripts if your distribution did not do it
for you already, especially the /etc/hotplug/firmware.agent.
http://linux-hotplug.sourceforge.net/ (Call /sbin/hotplug without arguments
to find out if the firmware agent is installed.)
The firmware.agent script expects firmware binaries in
/usr/lib/hotplug/firmware/. To avoid naming and versioning
conflicts we propose the following naming scheme:
/usr/lib/hotplug/firmware/dvb-{driver}-{ver}.fw for MPEG decoders etc.
/usr/lib/hotplug/firmware/dvb-fe-{driver}-{ver}.fw for frontends
{driver} name is the basename of the driver kernel module (e.g. dvb-ttpci)
{ver} is a version number/name that should change only when the
driver/firmware internal API changes (so users are free to install the
latest firmware compatible with the driver).
2) Manually loading the firmware into a driver
(currently only the dvb-ttpci / av7110 driver supports this)
Step a) Mount sysfs-filesystem.
Sysfs provides a means to export kernel data structures, their attributes,
and the linkages between them to userspace.
For detailed informations have a look at Documentation/filesystems/sysfs.txt
All you need to know at the moment is that firmware loading only works through
sysfs.
> mkdir /sys
> mount -t sysfs sysfs /sys
Step b) Exploring the firmware loading facilities
Firmware_class support is located in
/sys/class/firmware
> dir /sys/class/firmware
The "timeout" values specifies the amount of time that is waited before the
firmware upload process is cancelled. The default values is 10 seconds. If
you use a hotplug script for the firmware upload, this is sufficient. If
you want to upload the firmware by hand, however, this might be too fast.
> echo "180" > /sys/class/firmware/timeout
Step c) Getting a usable firmware file for the dvb-ttpci driver/av7110 card.
You can download the firmware files from
http://linuxtv.org/download/dvb/
Please note that in case of the dvb-ttpci driver this is *not* the "Root"
file you probably know from the 2.4 DVB releases driver.
The ttpci-firmware utility from linuxtv.org CVS can be used to
convert Dpram and Root files into a usable firmware image.
See dvb-kerrnel/scripts/ in http://linuxtv.org/cvs/.
> wget http://www.linuxtv.org/download/dvb/dvb-ttpci-01.fw
gets you the version 01 of the firmware fot the ttpci driver.
Step d) Loading the dvb-ttpci driver and loading the firmware
"modprobe" will take care that every needed module will be loaded
automatically (except the frontend driver)
> modprobe dvb-ttpci
The "modprobe" process will hang until
a) you upload the firmware or
b) the timeout occurs.
Change to another terminal and have a look at
> dir /sys/class/firmware/
total 0
drwxr-xr-x 2 root root 0 Jul 29 11:00 0000:03:05.0
-rw-r--r-- 1 root root 0 Jul 29 10:41 timeout
"0000:03:05.0" is the id for my dvb-c card. It depends on the pci slot,
so it changes if you plug the card to different slots.
You can upload the firmware like that:
> export DEVDIR=/sys/class/firmware/0000\:03\:05.0
> echo 1 > $DEVDIR/loading
> cat dvb-ttpci-01.fw > $DEVDIR/data
> echo 0 > $DEVDIR/loading
That's it. The driver should be up and running now.

Getting the Firmware
--------------------
The firmware can be found in the software update zip files on this page:
http://www.hauppauge.de/sw_dec.htm
The firmwares are named as follows:
DEC2000-t: STB_PC_T.bin
DEC2540-t: STB_PC_X.bin
DEC3000-s: STB_PC_S.bin
Note that firmwares since version 2.16 beta2 for the DEC2000-t give the device
the USB ID of the DEC3000-s. The driver copes with this.
Instructions follow for retrieving version 2.16 of the firmware:
wget http://hauppauge.lightpath.net/de/dec216.exe
unzip -j dec216.exe software/OEM/STB/App/Boot/STB_PC_T.bin
unzip -j dec216.exe software/OEM/STB/App/Boot/STB_PC_X.bin
unzip -j dec216.exe software/OEM/STB/App/Boot/STB_PC_S.bin
To download the firmware, use the following commands:
"get_dvb_firmware dec2000t"
"get_dvb_firmware dec2540t"
"get_dvb_firmware dec3000s"
Compilation Notes for 2.4 kernels
---------------------------------
For 2.4 kernels the firmware for the DECs is compiled into the driver itself.
The firmwares are expected to be in the build-2.4 directory at compilation
time.
mv STB_PC_T.bin build-2.4/dvb-ttusb-dec-2000t.fw
mv STB_PC_X.bin build-2.4/dvb-ttusb-dec-2540t.fw
mv STB_PC_S.bin build-2.4/dvb-ttusb-dec-3000s.fw
Copy the three files downloaded above into the build-2.4 directory.
Hotplug Firmware Loading for 2.6 kernels
----------------------------------------
For 2.6 kernels the firmware is loaded at the point that the driver module is
loaded. See Documentation/dvb/firmware.txt for more information.
loaded. See linux/Documentation/dvb/firmware.txt for more information.
mv STB_PC_T.bin /usr/lib/hotplug/firmware/dvb-ttusb-dec-2000t.fw
mv STB_PC_X.bin /usr/lib/hotplug/firmware/dvb-ttusb-dec-2540t.fw
mv STB_PC_S.bin /usr/lib/hotplug/firmware/dvb-ttusb-dec-3000s.fw

The DVB subsystem currently registers to the sysfs subsystem using the
"class_simple" interface.
This means that only the basic informations like module loading parameters
are presented through sysfs. Other things that might be interesting are
currently *not* available.
Nevertheless it's now possible to add proper udev rules so that the
DVB device nodes are created automatically.
We assume that you have udev already up and running and that have been
creating the DVB device nodes manually up to now due to the missing sysfs
support.
0. Don't forget to disable your current method of creating the
device nodes manually.
1. Unfortunately, you'll need a helper script to transform the kernel
sysfs device name into the well known dvb adapter / device naming scheme.
The script should be called "dvb.sh" and should be placed into a script
dir where udev can execute it, most likely /etc/udev/scripts/
So, create a new file /etc/udev/scripts/dvb.sh and add the following:
------------------------------schnipp------------------------------------------------
#!/bin/sh
/bin/echo $1 | /bin/sed -e 's,dvb\([0-9]\)\.\([^0-9]*\)\([0-9]\),dvb/adapter\1/\2\3,'
------------------------------schnipp------------------------------------------------
Don't forget to make the script executable with "chmod".
1. You need to create a proper udev rule that will create the device nodes
like you know them. All real distributions out there scan the /etc/udev/rules.d
directory for rule files. The main udev configuration file /etc/udev/udev.conf
will tell you the directory where the rules are, most likely it's /etc/udev/rules.d/
Create a new rule file in that directory called "dvb.rule" and add the following line:
------------------------------schnipp------------------------------------------------
KERNEL="dvb*", PROGRAM="/etc/udev/scripts/dvb.sh %k", NAME="%c"
------------------------------schnipp------------------------------------------------
If you want more control over the device nodes (for example a special group membership)
have a look at "man udev".
For every device that registers to the sysfs subsystem with a "dvb" prefix,
the helper script /etc/udev/scripts/dvb.sh is invoked, which will then
create the proper device node in your /dev/ directory.
