Documentation/dvb/udev

=============

======

The DVB subsystem currently registers to the sysfs subsystem using the

"class_simple" interface.

目前DVB子系统寄存器sysfs的子系统，采用“class_simple接口。

This means that only the basic information like module loading parameters

are presented through sysfs. Other things that might be interesting are

currently *not* available.

这意味着，只有模块加载参数的基本信息，如

通过sysfs。其他一些有趣的程序目前可能还是不可用的。

Nevertheless it's now possible to add proper udev rules so that the

DVB device nodes are created automatically.

然而，它现在允许添加适当的udev规则使DVB设备节点能够自动建立。

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.

我们假设你设备上的udev已经投入运行，并已

手动创建的DVB设备节点，到现在为止，由于没有的sysfs的支持。

0. Don't forget to disable your current method of creating the

device nodes manually.

当然不要忘了禁用当前的方法创建手动设备节点

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/

1。不幸的是，你会需要一个辅助脚本来转换内核

sysfs的设备名称为众所周知的DVB适配器/设备命名方案。

这个脚本应该被称为“dvb.sh”，并应放置到一个脚本

dir其中的udev可以执行它，最有可能的/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".

因此，创建一个新的文件在/ etc/ udev的/脚本/ dvb.sh并添加以下内容：

------------------------------schnipp------------------------------------------------

#!/bin/sh

/bin/echo $1 | /bin/sed -e 's,dvb\([0-9]\)\.\([^0-9]*\)\([0-9]\),dvb/adapter\1/\2\3,'

------------------------------schnipp------------------------------------------------

不要忘了用“文件模式”使脚本可执行。

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/

1。你需要创建一个适当的udev规则，将创建设备节点

你知道他们喜欢。所有真正有分布扫描在/etc/udev/rules.d中

规则文件的目录。主要的udev配置文件/etc/udev/udev.conf中指定

会告诉你所在的目录规则是，最有可能的是，它的/etc/udev/rules.d/中

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".

该目录文件中称为“dvb.rule”创建一个新的规则，并添加下面一行：

------------------------------schnipp------------------------------------------------

KERNEL="dvb*", PROGRAM="/etc/udev/scripts/dvb.sh %k", NAME="%c"

------------------------------schnipp------------------------------------------------

如果你想更多的控制设备节点（例如，一个特殊的群体成员）可以参考“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.

对于每个设备寄存器“DVB”前缀的sysfs子系统，

辅助脚本/etc/udev/scripts/dvb.sh的调用，然后将

建立适当的设备节点在/ dev/目录下的。
