Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

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.
