44 Chapter 1. Introduction
45
46 This document describes the revision 1.06 and 1.07 of SiS 900/7016
47 Fast Ethernet device driver under Linux. The driver is developed by
48 Silicon Integrated System Corp. and distributed freely under the GNU
49 General Public License (GPL). The driver can be compiled as a loadable
50 module and used under Linux kernel version 2.2.x. (rev. 1.06) With
51 minimal changes, the driver can also be used under 2.3.x and 2.4.x
52 kernel (rev. 1.07), please see Chapter 5. If you are intended to use
53 the driver for earlier kernels, you are on your own.
54
55 The driver is tested with usual TCP/IP applications including FTP,
56 Telnet, Netscape etc. and is used constantly by the developers.

58 Please send all comments/fixes/questions to Lei-Chun Chang.

61 Chapter 2. Changes
62
63 Changes made in Revision 1.07
64
65 1. Separation of sis900.c and sis900.h in order to move most constant
66 definition to sis900.h (many of those constants were corrected)
67 2. Clean up PCI detection, the pci-scan from Donald Becker were not
68 used, just simple pci_find_*.
69 3. MII detection is modified to support multiple mii transceiver.
70 4. Bugs in read_eeprom, mdio_* were removed.
71 5. Lot of sis900 irrelevant comments were removed/changed and more
72 comments were added to reflect the real situation.
73 6. Clean up of physical/virtual address space mess in buffer
74 descriptors.
75 7. Better transmit/receive error handling.
76 8. The driver now uses zero-copy single buffer management scheme to
77 improve performance.
78 9. Names of variables were changed to be more consistent.
79 10. Clean up of auo-negotiation and timer code.
80 11. Automatic detection and change of PHY on the fly.
81 12. Bug in mac probing fixed.
82 13. Fix 630E equalier problem by modifying the equalizer workaround
83 rule.
84 14. Support for ICS1893 10/100 Interated PHYceiver.
85 15. Support for media select by ifconfig.
86 16. Added kernel-doc extratable documentation.

122 Chapter 5. Installation
123
124 Silicon Integrated System Corp. is cooperating closely with core Linux
125 Kernel developers. The revisions of SiS 900 driver are distributed by
126 the usuall channels for kernel tar files and patches. Those kernel tar
127 files for official kernel and patches for kernel pre-release can be
128 download at official kernel ftp site and its mirrors. The 1.06
129 revision can be found in kernel version later than 2.3.15 and
130 pre-2.2.14, and 1.07 revision can be found in kernel version 2.4.0. If
131 you have no prior experience in networking under Linux, please read
132 Ethernet HOWTO and Networking HOWTO available from Linux Documentation
133 Project (LDP).
134
135 The driver is bundled in release later than 2.2.11 and 2.3.15 so this
136 is the most easy case. Be sure you have the appropriate packages for
137 compiling kernel source. Those packages are listed in Document/Changes
138 in kernel source distribution. If you have to install the driver other
139 than those bundled in kernel release, you should have your driver file
140 sis900.c and sis900.h copied into /usr/src/linux/drivers/net/ first.
141 There are two alternative ways to install the driver
142 _________________________________________________________________
143
144 Building the driver as loadable module
145
146 To build the driver as a loadable kernel module you have to
147 reconfigure the kernel to activate network support by
148
149 make menuconfig
150
151 Choose "Loadable module support --->", then select "Enable loadable
152 module support".
153
154 Choose "Network Device Support --->", select "Ethernet (10 or
155 100Mbit)". Then select "EISA, VLB, PCI and on board controllers", and
156 choose "SiS 900/7016 PCI Fast Ethernet Adapter support" to "M".
157
158 After reconfiguring the kernel, you can make the driver module by
159
160 make modules
161
162 The driver should be compiled with no errors. After compiling the
163 driver, the driver can be installed to proper place by
164
165 make modules_install
166
167 Load the driver into kernel by
168
169 insmod sis900
170
171 When loading the driver into memory, some information message can be
172 view by
173
174 dmesg
175
176 or
177 cat /var/log/message
178
179 If the driver is loaded properly you will have messages similar to
180 this:
181
182 sis900.c: v1.07.06 11/07/2000
183 eth0: SiS 900 PCI Fast Ethernet at 0xd000, IRQ 10, 00:00:e8:83:7f:a4.
184 eth0: SiS 900 Internal MII PHY transceiver found at address 1.
185 eth0: Using SiS 900 Internal MII PHY as default
186
187 showing the version of the driver and the results of probing routine.
188
189 Once the driver is loaded, network can be brought up by
190
191 /sbin/ifconfig eth0 IPADDR broadcast BROADCAST netmask NETMASK media TYPE
192
193 where IPADDR, BROADCAST, NETMASK are your IP address, broadcast
194 address and netmask respectively. TYPE is used to set medium type used
195 by the device. Typical values are "10baseT"(twisted-pair 10Mbps
196 Ethernet) or "100baseT" (twisted-pair 100Mbps Ethernet). For more
197 information on how to configure network interface, please refer to
198 Networking HOWTO.
199
200 The link status is also shown by kernel messages. For example, after
201 the network interface is activated, you may have the message:
202
203 eth0: Media Link On 100mbps full-duplex
204
205 If you try to unplug the twist pair (TP) cable you will get
206
207 eth0: Media Link Off
208
209 indicating that the link is failed.
210 _________________________________________________________________
211
212 Building the driver into kernel
213
214 If you want to make the driver into kernel, choose "Y" rather than "M"
215 on "SiS 900/7016 PCI Fast Ethernet Adapter support" when configuring
216 the kernel. Build the kernel image in the usual way
217
218 make dep
219
220 make clean
221
222 make bzlilo
223
224 Next time the system reboot, you have the driver in memory.

227 Chapter 6. Known Problems and Bugs
228
229 There are some known problems and bugs. If you find any other bugs
230 please mail to lcchang@sis.com.tw
231
232 1. AM79C901 HomePNA PHY is not thoroughly tested, there may be some
233 bugs in the "on the fly" change of transceiver.
234 2. A bug is hidden somewhere in the receive buffer management code,
235 the bug causes NULL pointer reference in the kernel. This fault is
236 caught before bad things happen and reported with the message:
237 eth0: NULL pointer encountered in Rx ring, skipping which can be
238 viewed with dmesg or cat /var/log/message.
239 3. The media type change from 10Mbps to 100Mbps twisted-pair ethernet
240 by ifconfig causes the media link down.
