<title>History</title>
<para>In February 2000, a new filesystem called <systemitem
class="filesystem">devfs</systemitem> was merged into the 2.3.46 kernel
and was made available during the 2.4 series of stable kernels. Although
- it was present in the kernel source itself, this method of creating
- devices dynamically never received overwhelming support from the core
- kernel developers.</para>

<para>The main problem with the approach adopted by <systemitem
- class="filesystem">devfs</systemitem> was the way it handled
- device detection, creation, and naming. The latter issue, that of
- device node naming, was perhaps the most critical. It is generally
- accepted that if device names are allowed to be configurable, then
- the device naming policy should be up to a system administrator, not
- imposed on them by any particular developer(s). The <systemitem

<title>Udev Implementation</title>
- <para>The <systemitem class="filesystem">sysfs</systemitem> filesystem
- was mentioned briefly above. One may wonder how <systemitem
- class="filesystem">sysfs</systemitem> knows about the devices present
- on a system and what device numbers should be used for them. Drivers
- that have been compiled into the kernel directly register their objects
- with <systemitem class="filesystem">sysfs</systemitem> as they are
- detected by the kernel. For drivers compiled as modules, this
- registration will happen when the module is loaded. Once the
- <systemitem class="filesystem">sysfs</systemitem> filesystem is mounted
- (on <filename class="directory">/sys</filename>), data which the built-in
- drivers registered with <systemitem class="filesystem">sysfs</systemitem>
- are available to userspace processes and to <command>udev</command> for
- device node creation.</para>
+ <sect3>
+ <title>Sysfs</title>
- <para>The <command>S10udev</command> initscript takes care of creating
- these device nodes when Linux is booted. This script starts by registering
- <command>/sbin/udevsend</command> as a hotplug event handler. Hotplug
- events (discussed below) are not usually generated during this stage,
- but <command>udev</command> is registered just in case they do occur.
- The <command>udevstart</command> program then walks through the
- <systemitem class="filesystem">/sys</systemitem> filesystem and creates
- devices under <filename class="directory">/dev</filename> that match the
- descriptions. For example, <filename>/sys/class/tty/vcs/dev</filename>
- contains the string <quote>7:0</quote> This string is used by
- <command>udevstart</command> to create <filename>/dev/vcs</filename>
- with major number <emphasis>7</emphasis> and minor <emphasis>0</emphasis>.
- The names and permissions of the nodes created under the <filename
- class="directory">/dev</filename> directory are configured according to
- the rules specified in the files within the <filename
- class="directory">/etc/udev/rules.d/</filename> directory. These are
- numbered in a similar fashion to the CLFS-Bootscripts package. If
- <command>udev</command> can't find a rule for the device it is creating,
- it will default permissions to <emphasis>660</emphasis> and ownership to
- <emphasis>root:root</emphasis>.</para>

- <para>Once the above stage is complete, all devices that were already
- present and have compiled-in drivers will be available for use. This
- leads us to the devices that have modular drivers.</para>
+ </sect3>
- <para>Earlier, we mentioned the concept of a <quote>hotplug event
- handler.</quote> When a new device connection is detected by the kernel,
- the kernel will generate a hotplug event and look at the file
- <filename>/proc/sys/kernel/hotplug</filename> to determine the userspace
- program that handles the device's connection. The <command>udev</command>
- bootscript registered <command>udevsend</command> as this handler. When
- these hotplug events are generated, the kernel will tell
- <command>udev</command> to check the <filename
- class="directory">/sys</filename> filesystem for the information
- pertaining to this new device and create the <filename
- class="directory">/dev</filename> entry for it.</para>
+ <sect3>
+ <title>Udev Bootscript</title>
- <para>This brings us to one problem that exists with
- <command>udev</command>, and likewise with <systemitem
- class="filesystem">devfs</systemitem> before it. It is commonly
- referred to as the <quote>chicken and egg</quote> problem. Most
- Linux distributions handle loading modules via entries in
- <filename>/etc/modules.conf</filename>. Access to a device node causes
- the appropriate kernel module to load. With <command>udev</command>,
- this method will not work because the device node does not exist until
- the module is loaded. To solve this, the <command>S05modules</command>
- bootscript was added to the CLFS-Bootscripts package, along with the
- <filename>/etc/sysconfig/modules</filename> file. By adding module
- names to the <filename>modules</filename> file, these modules will be
- loaded when the computer starts up. This allows <command>udev</command>
- to detect the devices and create the appropriate device nodes.</para>
+ <para>The <command>S10udev</command> initscript takes care of creating
+ device nodes when Linux is booted. The script unsets the uevent handler
+ from the default of <command>/sbin/hotplug</command>. This is done
+ because the kernel no longer needs to call out to an external binary.
+ Instead <command>udevd</command> will listen on a netlink socket for
+ uevents that the kernel raises. Next, the bootscript copies any static
+ device nodes that exist in <filename
+ class="directory">/lib/udev/devices</filename> to <filename
+ class="directory">/dev</filename>. This is necessary because some
devices,
+ directories, and symlinks are needed before the dynamic device handling
+ processes are available during the early stages of booting a system.
+ Creating static device nodes in <filename
+ class="directory">/lib/udev/devices</filename> also provides an easy
+ workaround for devices that are not supported by the dynamic device
+ handling infrastructure. The bootscript then starts the Udev daemon,
+ <command>udevd</command>, which will act on any uevents it receives.
+ Finally, the bootscript forces the kernel to replay uevents for any
+ devices that have already been registered and then waits for
+ <command>udevd</command> to handle them.</para>
- <para>Note that on slower machines or for drivers that create a lot
- of device nodes, the process of creating devices may take a few
- seconds to complete. This means that some device nodes may not be
- immediately accessible.</para>

+ <para>To obtain the right major and minor number for a device, Udev
relies

+ <para>Device drivers compiled as modules may have aliases built into
them.
+ Aliases are visible in the output of the <command>modinfo</command>
+ program and are usually related to the bus-specific identifiers of
devices
+ supported by a module. For example, the <emphasis>snd-fm801</emphasis>
+ driver supports PCI devices with vendor ID 0x1319 and device ID 0x0801,
+ and has an alias of
<quote>pci:v00001319d00000801sv*sd*bc04sc01i*</quote>.
+ For most devices, the bus driver exports the alias of the driver that
+ would handle the device via <systemitem
+ class="filesystem">sysfs</systemitem>. E.g., the
+ <filename>/sys/bus/pci/devices/0000:00:0d.0/modalias</filename> file
+ might contain the string
+ <quote>pci:v00001319d00000801sv00001319sd00001319bc04sc01i00</quote>.
+ The rules that LFS installs will cause <command>udevd</command> to call
+ out to <command>/sbin/modprobe</command> with the contents of the
+ <envar>MODALIAS</envar> uevent environment variable (that should be the
+ same as the contents of the <filename>modalias</filename> file in sysfs),

+ <sect3>
+ <title>A kernel module is not loaded automatically</title>
- <para>This is most common with third party drivers from outside the
- kernel tree. Udev will be unable to automatically create device nodes
- for such drivers. Use the <filename>/etc/sysconfig/createfiles</filename>
- configuration file to manually create the devices. Consult the
- <filename>devices.txt</filename> file inside the kernel documentation
- or the documentation for that driver to find the proper major/minor
- numbers.</para>
+ <para>Udev will only load a module if it has a bus-specific alias and the
+ bus driver properly exports the necessary aliases to <systemitem
+ class="filesystem">sysfs</systemitem>. In other cases, one should
+ arrange module loading by other means. With Linux-&linux-version;, Udev
is
+ known to load properly-written drivers for INPUT, IDE, PCI, USB, SCSI,
+ SERIO and FireWire devices.</para>
- <para>2) A non-hardware device is required. This is most common with
- the Advanced Linux Sound Architecture (ALSA) project's Open Sound
- System (OSS) compatibility module. These types of devices can be
- handled in one of two ways:</para>
+ <para>To determine if the device driver you require has the necessary

- For example:</para>

+ <para>If there is no <filename>modalias</filename> file in the relevant

with
