SPDX-License-Identifier: GPL-2.0 + +======================================== +The COPS LocalTalk Linux driver (cops.c) +======================================== + +By Jay Schulist <jschlst@samba.org> + +This driver has two modes and they are: Dayna mode and Tangent mode. +Each mode corresponds with the type of card. It has been found +that there are 2 main types of cards and all other cards are +the same and just have different names or only have minor differences +such as more IO ports. As this driver is tested it will +become more clear exactly what cards are supported. + +Right now these cards are known to work with the COPS driver. The +LT-200 cards work in a somewhat more limited capacity than the +DL200 cards, which work very well and are in use by many people. + +TANGENT driver mode: + - Tangent ATB-II, Novell NL-1000, Daystar Digital LT-200 + +DAYNA driver mode: + - Dayna DL2000/DaynaTalk PC (Half Length), COPS LT-95, + - Farallon PhoneNET PC III, Farallon PhoneNET PC II + +Other cards possibly supported mode unknown though: + - Dayna DL2000 (Full length) + +The COPS driver defaults to using Dayna mode. To change the driver's +mode if you built a driver with dual support use board_type=1 or +board_type=2 for Dayna or Tangent with insmod. + +Operation/loading of the driver +=============================== + +Use modprobe like this: /sbin/modprobe cops.o (IO #) (IRQ #) +If you do not specify any options the driver will try and use the IO = 0x240, +IRQ = 5.

SPDX-License-Identifier: GPL-2.0 + +=========== +LTPC Driver +=========== + +This is the ALPHA version of the ltpc driver. + +In order to use it, you will need at least version 1.3.3 of the +netatalk package, and the Apple or Farallon LocalTalk PC card. +There are a number of different LocalTalk cards for the PC; this +driver applies only to the one with the 65c02 processor chip on it. + +To include it in the kernel, select the CONFIG_LTPC switch in the +configuration dialog. You can also compile it as a module. + +While the driver will attempt to autoprobe the I/O port address, IRQ +line, and DMA channel of the card, this does not always work. For +this reason, you should be prepared to supply these parameters +yourself. (see "Card Configuration" below for how to determine or +change the settings on your card) + +When the driver is compiled into the kernel, you can add a line such +as the following to your /etc/lilo.conf:: + + append="ltpc=0x240,9,1" + +where the parameters (in order) are the port address, IRQ, and DMA +channel. The second and third values can be omitted, in which case +the driver will try to determine them itself. + +If you load the driver as a module, you can pass the parameters "io=", +"irq=", and "dma=" on the command line with insmod or modprobe, or add +them as options in a configuration file in /etc/modprobe.d/ directory:: + + alias lt0 ltpc # autoload the module when the interface is configured + options ltpc io=0x240 irq=9 dma=1 + +Before starting up the netatalk demons (perhaps in rc.local), you +need to add a line such as:: + + /sbin/ifconfig lt0 127.0.0.42 + +The address is unimportant - however, the card needs to be configured +with ifconfig so that Netatalk can find it. + +The appropriate netatalk configuration depends on whether you are +attached to a network that includes AppleTalk routers or not. If, +like me, you are simply connecting to your home Macintoshes and +printers, you need to set up netatalk to "seed". The way I do this +is to have the lines:: + + dummy -seed -phase 2 -net 2000 -addr 2000.26 -zone "1033" + lt0 -seed -phase 1 -net 1033 -addr 1033.27 -zone "1033" + +in my atalkd.conf. What is going on here is that I need to fool +netatalk into thinking that there are two AppleTalk interfaces +present; otherwise, it refuses to seed. This is a hack, and a more +permanent solution would be to alter the netatalk code. Also, make +sure you have the correct name for the dummy interface - If it's +compiled as a module, you will need to refer to it as "dummy0" or some +such. + +If you are attached to an extended AppleTalk network, with routers on +it, then you don't need to fool around with this -- the appropriate +line in atalkd.conf is:: + + lt0 -phase 1 + + +Card Configuration +================== + +The interrupts and so forth are configured via the dipswitch on the +board. Set the switches so as not to conflict with other hardware. + + Interrupts -- set at most one. If none are set, the driver uses + polled mode. Because the card was developed in the XT era, the + original documentation refers to IRQ2.

However, you can't just +treat the LocalTalk device like an ordinary Ethernet device, even if +that's what it looks like to Netatalk. + +Instead, you follow the same procedure as for doing IP in EtherTalk. +See Documentation/networking/ipddp.rst for more information about the +kernel driver and userspace tools needed. + + +Bugs +==== + +IRQ autoprobing often doesn't work on a cold boot. To get around +this, either compile the driver as a module, or pass the parameters +for the card to the kernel as described above. + +Also, as usual, autoprobing is not recommended when you use the driver +as a module. (though it usually works at boot time, at least) + +Polled mode is *really* slow sometimes, but this seems to depend on +the configuration of the network. + +It may theoretically be possible to use two LTPC cards in the same +machine, but this is unsupported, so if you really want to do this, +you'll probably have to hack the initialization code a bit. + + +Thanks +====== + +Thanks to Alan Cox for helpful discussions early on in this +work, and to Denis Hainsworth for doing the bleeding-edge testing. + +Bradford Johnson <bradford@math.umn.edu> + +Updated 11/09/1998 by David Huggins-Daines <dhd@debian.org> diff --git a/Documentation/networking/device_drivers/atm/cxacru-cf.py b/Documentation/networking/device_drivers/atm/cxacru-cf.py new file mode 100644 index 000000000000..b41d298398c8 --- /dev/null +++ b/Documentation/networking/device_drivers/atm/cxacru-cf.py @@ -0,0 +1,48 @@ +#!/usr/bin/env python +# Copyright 2009 Simon Arlott +# +# This program is free software; you can redistribute it and/or modify it +# under the terms of the GNU General Public License as published by the Free +# Software Foundation; either version 2 of the License, or (at your option) +# any later version. +# +# This program is distributed in the hope that it will be useful, but WITHOUT +# ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or +# FITNESS FOR A PARTICULAR PURPOSE.
