4 Preparing the Driver Installation Package
============================================
Before the sk98lin driver installation script can be invoked, the
installation package needs to be unpacked:
1. Login as 'root'.
2. Unpack the driver installation package using the command
# tar xfvj install-???.tar.bz2
or
# bunzip2 -c install-???.tar.bz2 | tar xfv -
***
5 Driver Installation
======================
1. After the driver installation package is unpacked, type the following
commands to start the sk98lin driver build process:
# cd DriverInstall
# ./install.sh
2. Select the driver installation mode (see following subchapters).
3. Wait for the driver build process to finish.
Depending on the installation mode you selected, the driver is either
compiled and installed or a kernel patch is generated.
***
5.1 Installation Mode
----------------------
Selecting this installation mode the driver sources shipped
with the install package are compiled and the resulting driver
module object file is installed to a suitable location (usually somewhere
below directory /lib/modules/...).
No source files of the driver are installed into a kernel directory.
Only the driver module object file and the man page of the driver are
installed onto your system permanently.
The term "installation" reflects the fact that the build
process runs automatically without any user interaction. In case
of installation problems, the driver installation script autonomously
tries to solve the problem (if this is possible).
After compilation has finished, the initial system state and
configuration is recovered and all (possibly) backed-up system
files are restored from the initial configuration.
***
5.2 Patch Generation Mode
--------------------------
Selecting this installation mode, a driver patch is created which can
be applied to your Linux kernel (instead of compiling and installing
the driver on your machine).
Usually, a patch is applied when a recompilation of the Linux
kernel is intended and the latest driver sources need to be
installed permanently in the appropriate driver directory of
the Linux kernel.
NOTE: You still have to compile your patched Linux kernel in
order to effectively use the latest driver sources shipped
with this installation package!
***
6 Patch Generation and Recompilation of the Kernel
===================================================
If a new patch has been created using the sk98lin driver installation
script,
- it needs to be applied against the Linux kernel sources
and
- the Linux kernel has to be recompiled in order to use the
sk98lin driver.
***
6.1 Downloading and Unpacking the Linux Kernel
-----------------------------------------------
Before the sk98lin driver installation script is used to generate
a driver patch, a Linux kernel needs to be installed. If you already have
installed a Linux kernel in the directory /usr/src, you can skip this
paragraph and immediately continue with the paragraph describing
how to apply the patch against the Linux kernel.
To patch the Linux Kernel, proceed as follows:
1. Login as 'root'.
2. Download the original Linux source code named linux-a.b.c.tar.bz
from ftp.kernel.org into the directory /usr/src
3. Go to the directory /usr/src and remove all symbolic links to old
Linux sources using the commands:
# cd /usr/src
# rm linux
4. Unpack the original Linux source code using the command:
# tar xvjf linux-a.b.c.tar.bz
After the sources have been installed, they can be found in a
directory named /usr/src/linux-a.b.c or /usr/src/linux.
5. If the symbolic link to the target kernel source directory
(/usr/src/linux) does not exist, create it manually with the
following commands:
# cd /usr/src
# ln -s linux.a.b.c linux
***
6.2 Generating the Driver Patch
--------------------------------
1. Run the sk98lin driver installation script.
2. Choose "generate patch".
3. Follow the instructions of the install script.
***
6.3 Applying the Driver Patch
------------------------------
To apply the generated Patch into the kernel use the following
commands:
# cd /usr/src/linux
# cat /patch-location/sk98lin__vX.XX_a_b_c_patch | patch -p1
***
6.4 Configuring the Linux Kernel
---------------------------------
1. Go to the directory /usr/src/linux:
# cd /usr/src/linux
2. Depending on your current environment mode (console or graphical),
you have to invoke different Kernel configuration commands:
- In the console mode, execute the command:
# make menuconfig
- In the graphical mode, execute the command:
# make xconfig
- In the graphical mode with kernel 2.6, execute the command:
# make gconfig
This builds a few programs and displays the kernel
configuration menu. In this menu you can modify several options
of the kernel configuration.
3. Select the options you want to compile into the new kernel.
- For kernel 2.4.x family:
a. Select the menu "Network Device Support".
b. Select "Ethernet (1000 Mbit)".
- For kernel 2.6.x family:
a. Select the menu "device drivers"
b. Select the menu "Network Device Support".
c. Select "Ethernet (1000 Mbit)".
4. Select how to use the driver in the Linux kernel.
- To compile the driver as a module, mark
"Marvell Yukon Chipset/SysKonnect SK-98xx Support" with (M).
- To integrate the driver permanently into the kernel, mark
"Marvell Yukon Chipset/SysKonnect SK-98xx Support" with (*).
5. Select if you want to use Rx polling (NAPI).
- To enable Rx polling of the driver, mark
"Use Rx polling (NAPI)" with (*).
- To disable Rx polling of the driver, do not mark
"Use Rx polling (NAPI)".
6. Select "Exit".
7. Select the menu "Loadable module support".
8. Select "Enable loadable module support".
9. Select "Kernel module loader".
10. Configure other options depending on your needs (e.g. SCSI).
11. To quit the configuration, select "Exit".
12. When the message "Do you wish to save your new kernel configuration"
is displayed, select "Yes".
***
6.5 Compiling the Linux Kernel
-------------------------------
After the Linux configuration has been finished, it can be compiled.
1. Create all dependencies (unnecessary for kernel 2.6.x):
# make dep
2. Build the Linux kernel binary:
# make clean bzImage.
3. Build all modules and install them below /lib/modules:
# make modules
# make modules_install
***
6.6 Installing the Compiled Linux Kernel
-----------------------------------------
When the compilation of the Linux kernel has been finished it needs
to be installed to the boot directory. In addition to this, the boot
loader (LILO, GRUB etc.) needs to be notified about the new Linux kernel.
1. Install the new kernel by copying it into your boot directory
by executing the commands (e.g. on Intel/x86 machines):
# cp arch/i386/boot/bzImage /boot/vmlinuz-new
# cp System.map /boot/System.map-new.
2. Edit the boot loader configuration file to boot the new kernel.
For details refer to man page and documentation of your boot loader
(LILO, GRUB).
3. Reboot your system with the new kernel.
***
7 Manual Module Loading
========================
After booting the Linux kernel and compiling the driver as a loadable
kernel module (LKM), the driver needs to be loaded.
1. Enter "modprobe sk98lin".
2. If any Marvell Yukon(TM) based adapter is installed in your computer
and you have a mounted /proc file system, execute the command:
# ls /proc/net/sk98lin/
This should produce an output line of the following format:
eth0 eth1 ...
which indicates that your adapter(s) has/have been found and initialized.
NOTE: For further information (e.g. the driver parameters) refer to
the sk98lin.txt file.
***
8 Unloading the Module
=======================
Unloading of the sk98lin driver is only possible if it has been
compiled as loadable kernel module. Before the driver module can be unloaded,
all interfaces of the driver module need to be stopped using the following
sequence of commands:
1. Execute the command "ifconfig YOUR_DEVICE down":
# ifconfig eth0 down
# ifconfig eth1 down
# ifconfig ... down
2. Execute the command "rmmod sk98lin".
***
9 Driver Parameters
====================
When loading the driver as a kernel module, additional parameters
can be passed to the driver for configuration.
Those parameters can be passed in two ways: You can either
- state them on the modprobe command line
or
- set them in the file /etc/modules.conf (old name:
/etc/conf.modules), in order to force the kernel module loader
to pass them to the driver at load-time.
NOTE: For further information about the driver parameters and their
possible values refer to the sk98lin.txt file.
***
10 Ethtool Commands
====================
The sk98lin driver provides built-in ethtool support. The ethtool
can be used to display or modify interface specific configurations.
NOTE: For further information about provided ethtool commands and their
possible values refer to the sk98lin.txt file.
***
11 Troubleshooting
===================
If any problems occur during the installation process, check the
following list of known problems. If you cannot find your problem
in the list below, please contact SysKonnect's technical support
for help (linux@syskonnect.de). When contacting our technical
support, please ensure that the following information is available:
- the 'install.log' file created by the install script 'install.sh'
- System Manufacturer and HW Informations (CPU, Memory... )
- PCI-Boards in your system
- Distribution
- Kernel version
- Driver version
Problem: The SK-98xx adapter cannot be found by the driver.
Solution: In /proc/pci search for the following entry:
'Ethernet controller: SysKonnect SK-98xx ...'
If this entry exists, the SK-98xx or SK-98xx V2.0 adapter has
been found by the system and should be operational.
If this entry does not exist or if the file '/proc/pci' is not
found, there may be a hardware problem or the PCI support may
not be enabled in your kernel.
The adapter can be checked using the diagnostics program which
is available on the SysKonnect web site:
www.syskonnect.com
Problem: Programs such as 'ifconfig' or 'route' cannot be found or the
error message 'Operation not permitted' is displayed.
Reason: You are not logged in as user 'root'.
Solution: Logout and login as 'root' or change to 'root' via 'su'.
Problem: The driver can be started, but if an ip address is assigned
to an adapter no link up indication appears although it is
connected to the network. It is also not possible to receive
or transmit any packets; e.g. 'ping' does not work.
Reason: The adapter does not receive any interrupts from the Linux
system. This can happen when using the APIC (Advanced
Programmable Interrupt Controller) of an SMP compiled kernel
on a UP envrionment.
Solution: Use the Linux kernel parameters 'noapic' or 'nolapic' when
booting your kernel. This can be done by adding those kernel
parameters to the boot manager kernel selection menu (either
/boot/grub/menu.lst (GRUB) or /etc/lilo.conf (LILO)).
When you build a kernel, deselect option CONFIG_X86_LOCAL_APIC.
Problem: The driver can be started, the adapter is connected to the
network and a link up indication is displayed, but you cannot
receive or transmit any packets; e.g. 'ping' does not work.
Reason: There is an incorrect route in your routing table or the
remote host is unreachable.
Solution: Check the routing table with the command 'route' and read the
manual help pages dealing with routes (enter 'man route').
Check the connection to the remote host system.
Problem: At driver start, the following error message is displayed:
"eth0: -- ERROR --
Class: internal Software error
Nr: 0xcc
Msg: SkGeInitPort() cannot init running ports"
Reason: You are using a driver compiled for single processor machines
on a multiprocessor machine with SMP (Symmetric MultiProcessor)
kernel.
Solution: Configure your kernel appropriately and recompile the kernel.
