26 | This file assumes that you are using the Computone drivers which are | |
27 | integrated into the kernel sources. For updating the drivers or installing | |
28 | drivers into kernels which do not already have Computone drivers, please | |
29 | refer to the instructions in the README.computone file in the driver patch. | |
30 | ||
31 | ||
32 | 1. INTRODUCTION | |
33 | ||
34 | This driver supports the entire family of Intelliport II/Plus controllers | |
35 | with the exception of the MicroChannel controllers. It does not support | |
36 | products previous to the Intelliport II. | |
37 | ||
38 | This driver was developed on the v2.0.x Linux tree and has been tested up | |
39 | to v2.4.14; it will probably not work with earlier v1.X kernels,. | |
40 | ||
41 | ||
42 | 2. QUICK INSTALLATION | |
43 | ||
44 | Hardware - If you have an ISA card, find a free interrupt and io port. | |
45 | List those in use with `cat /proc/interrupts` and | |
46 | `cat /proc/ioports`. Set the card dip switches to a free | |
47 | address. You may need to configure your BIOS to reserve an | |
48 | irq for an ISA card. PCI and EISA parameters are set | |
49 | automagically. Insert card into computer with the power off | |
50 | before or after drivers installation. | |
51 | ||
52 | Note the hardware address from the Computone ISA cards installed into | |
53 | the system. These are required for editing ip2.c or editing | |
54 | /etc/modprobe.conf, or for specification on the modprobe | |
55 | command line. | |
56 | ||
57 | Note that the /etc/modules.conf should be used for older (pre-2.6) | |
58 | kernels. | |
59 | ||
60 | Software - | |
61 | ||
62 | Module installation: | |
63 | ||
64 | a) Determine free irq/address to use if any (configure BIOS if need be) | |
65 | b) Run "make config" or "make menuconfig" or "make xconfig" | |
66 | Select (m) module for CONFIG_COMPUTONE under character | |
67 | devices. CONFIG_PCI and CONFIG_MODULES also may need to be set. | |
68 | c) Set address on ISA cards then: | |
69 | edit /usr/src/linux/drivers/char/ip2.c if needed | |
70 | or | |
71 | edit /etc/modprobe.conf if needed (module). | |
72 | or both to match this setting. | |
73 | d) Run "make modules" | |
74 | e) Run "make modules_install" | |
75 | f) Run "/sbin/depmod -a" | |
76 | g) install driver using `modprobe ip2 <options>` (options listed below) | |
77 | h) run ip2mkdev (either the script below or the binary version) | |
78 | ||
79 | ||
80 | Kernel installation: | |
81 | ||
82 | a) Determine free irq/address to use if any (configure BIOS if need be) | |
83 | b) Run "make config" or "make menuconfig" or "make xconfig" | |
84 | Select (y) kernel for CONFIG_COMPUTONE under character | |
85 | devices. CONFIG_PCI may need to be set if you have PCI bus. | |
86 | c) Set address on ISA cards then: | |
87 | edit /usr/src/linux/drivers/char/ip2.c | |
88 | (Optional - may be specified on kernel command line now) | |
89 | d) Run "make zImage" or whatever target you prefer. | |
90 | e) mv /usr/src/linux/arch/i386/boot/zImage to /boot. | |
91 | f) Add new config for this kernel into /etc/lilo.conf, run "lilo" | |
92 | or copy to a floppy disk and boot from that floppy disk. | |
93 | g) Reboot using this kernel | |
94 | h) run ip2mkdev (either the script below or the binary version) | |
95 | ||
96 | Kernel command line options: | |
97 | ||
98 | When compiling the driver into the kernel, io and irq may be | |
99 | compiled into the driver by editing ip2.c and setting the values for | |
100 | io and irq in the appropriate array. An alternative is to specify | |
101 | a command line parameter to the kernel at boot up. | |
102 | ||
103 | ip2=io0,irq0,io1,irq1,io2,irq2,io3,irq3 | |
104 | ||
105 | Note that this order is very different from the specifications for the | |
106 | modload parameters which have separate IRQ and IO specifiers. | |
107 | ||
108 | The io port also selects PCI (1) and EISA (2) boards. | |
109 | ||
110 | io=0 No board | |
111 | io=1 PCI board | |
112 | io=2 EISA board | |
113 | else ISA board io address | |
114 | ||
115 | You only need to specify the boards which are present. | |
116 | ||
117 | Examples: | |
118 | ||
119 | 2 PCI boards: | |
120 | ||
121 | ip2=1,0,1,0 | |
122 | ||
123 | 1 ISA board at 0x310 irq 5: | |
124 | ||
125 | ip2=0x310,5 | |
126 | ||
127 | This can be added to and "append" option in lilo.conf similar to this: | |
128 | ||
129 | append="ip2=1,0,1,0" | |
130 | ||
131 | ||
132 | 3. INSTALLATION | |
133 | ||
134 | Previously, the driver sources were packaged with a set of patch files | |
135 | to update the character drivers' makefile and configuration file, and other | |
136 | kernel source files. A build script (ip2build) was included which applies | |
137 | the patches if needed, and build any utilities needed. | |
138 | What you receive may be a single patch file in conventional kernel | |
139 | patch format build script. That form can also be applied by | |
140 | running patch -p1 < ThePatchFile. Otherwise run ip2build. | |
141 | ||
142 | The driver can be installed as a module (recommended) or built into the | |
143 | kernel. This is selected as for other drivers through the `make config` | |
144 | command from the root of the Linux source tree. If the driver is built | |
145 | into the kernel you will need to edit the file ip2.c to match the boards | |
146 | you are installing. See that file for instructions. If the driver is | |
147 | installed as a module the configuration can also be specified on the | |
148 | modprobe command line as follows: | |
149 | ||
150 | modprobe ip2 irq=irq1,irq2,irq3,irq4 io=addr1,addr2,addr3,addr4 | |
151 | ||
152 | where irqnum is one of the valid Intelliport II interrupts (3,4,5,7,10,11, | |
153 | 12,15) and addr1-4 are the base addresses for up to four controllers. If | |
154 | the irqs are not specified the driver uses the default in ip2.c (which | |
155 | selects polled mode). If no base addresses are specified the defaults in | |
156 | ip2.c are used. If you are autoloading the driver module with kerneld or | |
157 | kmod the base addresses and interrupt number must also be set in ip2.c | |
158 | and recompile or just insert and options line in /etc/modprobe.conf or both. | |
159 | The options line is equivalent to the command line and takes precedence over | |
160 | what is in ip2.c. | |
161 | ||
162 | /etc/modprobe.conf sample: | |
163 | options ip2 io=1,0x328 irq=1,10 | |
164 | alias char-major-71 ip2 | |
165 | alias char-major-72 ip2 | |
166 | alias char-major-73 ip2 | |
167 | ||
168 | The equivalent in ip2.c: | |
169 | ||
170 | static int io[IP2_MAX_BOARDS]= { 1, 0x328, 0, 0 }; | |
171 | static int irq[IP2_MAX_BOARDS] = { 1, 10, -1, -1 }; | |
172 | ||
173 | The equivalent for the kernel command line (in lilo.conf): | |
174 | ||
175 | append="ip2=1,1,0x328,10" | |
176 | ||
177 | ||
178 | Note: Both io and irq should be updated to reflect YOUR system. An "io" | |
179 | address of 1 or 2 indicates a PCI or EISA card in the board table. | |
180 | The PCI or EISA irq will be assigned automatically. | |
181 | ||
182 | Specifying an invalid or in-use irq will default the driver into | |
183 | running in polled mode for that card. If all irq entries are 0 then | |
184 | all cards will operate in polled mode. | |
185 | ||
186 | If you select the driver as part of the kernel run : | |
187 | ||
188 | make zlilo (or whatever you do to create a bootable kernel) | |
189 | ||
190 | If you selected a module run : | |
191 | ||
192 | make modules && make modules_install | |
193 | ||
194 | The utility ip2mkdev (see 5 and 7 below) creates all the device nodes | |
195 | required by the driver. For a device to be created it must be configured | |
196 | in the driver and the board must be installed. Only devices corresponding | |
197 | to real IntelliPort II ports are created. With multiple boards and expansion | |
198 | boxes this will leave gaps in the sequence of device names. ip2mkdev uses | |
199 | Linux tty naming conventions: ttyF0 - ttyF255 for normal devices, and | |
200 | cuf0 - cuf255 for callout devices. | |
201 | ||
202 | ||
203 | 4. USING THE DRIVERS | |
204 | ||
205 | As noted above, the driver implements the ports in accordance with Linux | |
206 | conventions, and the devices should be interchangeable with the standard | |
207 | serial devices. (This is a key point for problem reporting: please make | |
208 | sure that what you are trying do works on the ttySx/cuax ports first; then | |
209 | tell us what went wrong with the ip2 ports!) | |
210 | ||
211 | Higher speeds can be obtained using the setserial utility which remaps | |
212 | 38,400 bps (extb) to 57,600 bps, 115,200 bps, or a custom speed. | |
213 | Intelliport II installations using the PowerPort expansion module can | |
214 | use the custom speed setting to select the highest speeds: 153,600 bps, | |
215 | 230,400 bps, 307,200 bps, 460,800bps and 921,600 bps. The base for | |
216 | custom baud rate configuration is fixed at 921,600 for cards/expansion | |
217 | modules with ST654's and 115200 for those with Cirrus CD1400's. This | |
218 | corresponds to the maximum bit rates those chips are capable. | |
219 | For example if the baud base is 921600 and the baud divisor is 18 then | |
220 | the custom rate is 921600/18 = 51200 bps. See the setserial man page for | |
221 | complete details. Of course if stty accepts the higher rates now you can | |
222 | use that as well as the standard ioctls(). | |
223 | ||
224 | ||
225 | 5. ip2mkdev and assorted utilities... | |
226 | ||
227 | Several utilities, including the source for a binary ip2mkdev utility are | |
228 | available under .../drivers/char/ip2. These can be build by changing to | |
229 | that directory and typing "make" after the kernel has be built. If you do | |
230 | not wish to compile the binary utilities, the shell script below can be | |
231 | cut out and run as "ip2mkdev" to create the necessary device files. To | |
232 | use the ip2mkdev script, you must have procfs enabled and the proc file | |
233 | system mounted on /proc. | |
234 | ||
235 | ||
236 | 6. NOTES | |
237 | ||
238 | This is a release version of the driver, but it is impossible to test it | |
239 | in all configurations of Linux. If there is any anomalous behaviour that | |
240 | does not match the standard serial port's behaviour please let us know. | |
241 | ||
242 | ||
243 | 7. ip2mkdev shell script | |
244 | ||
245 | Previously, this script was simply attached here. It is now attached as a | |
246 | shar archive to make it easier to extract the script from the documentation. | |
247 | To create the ip2mkdev shell script change to a convenient directory (/tmp | |
248 | works just fine) and run the following command: | |
249 | ||
250 | unshar Documentation/computone.txt | |
251 | (This file) | |
252 | ||
253 | You should now have a file ip2mkdev in your current working directory with | |
254 | permissions set to execute. Running that script with then create the | |
255 | necessary devices for the Computone boards, interfaces, and ports which | |
256 | are present on you system at the time it is run. | |
257 | ||
258 | ||
259 | #!/bin/sh | |
260 | # This is a shell archive (produced by GNU sharutils 4.2.1). | |
