isdn: remove hisax driver
With the decline of ISDN, this seems to have become almost completely
obsolete, and even in the past years before that, almost all remaining
users appear to have used mISDN instead.
Birger Harzenetter noted that he is still using i4l/hisax to take
advantage of the 'divert' driver for call diversion, but otherwise uses
mISDN on the same hardware. This is a rare edge case as far as I
can tell, but we are still breaking an actively used work flow
(see https://xkcd.com/1172/).
We debated moving i4l/hisax to staging as an intermediate step, but as
he is not likely to change the setup, and that would just delay breaking
this use case. The alternatives here are to stay on stable kernels
< 5.2, to create an external driver repository for isdn4linux, or to
add divert functionality to mISDN.

-However, if you wish to modify the HiSax sources, please note the following:
-
-HiSax has passed the ITU approval test suite with ELSA Quickstep ISDN cards
-and Eicon Technology Diva 2.01 PCI card.
-The certification is only valid for the combination of the tested software
-version and the tested hardware. Any changes to the HiSax source code may
-therefore affect the certification.
-
-Additional ITU approval tests have been carried out for all generic cards
-using Colognechip single chip solutions HFC-S PCI A for PCI cards as well
-as HFC-S USB based USB ISDN ta adapters.
-These tests included all layers 1-3 and as well all functional tests for
-the layer 1. Because all hardware based on these chips are complete ISDN
-solutions in one chip all cards and USB-TAs using these chips are to be
-regarded as approved for those tests. Some additional electrical tests
-of the layer 1 which are independent of the driver and related to a
-special hardware used will be regarded as approved if at least one
-solution has been tested including those electrical tests. So if cards
-or tas have been completely approved for any other os, the approval
-for those electrical tests is valid for linux, too.
-Please send any questions regarding this drivers or approval abouts to
-werner@isdn-development.de
-Additional information and the type approval documents will be found
-shortly on the Colognechip website www.colognechip.com
-
-If you change the main files of the HiSax ISDN stack, the certification will
-become invalid. Because in most countries it is illegal to connect
-unapproved ISDN equipment to the public network, I have to guarantee that
-changes in HiSax do not affect the certification.
-
-In order to make a valid certification apparent to the user, I have built in
-some validation checks that are made during the make process. The HiSax main
-files are protected by md5 checksums and the md5sum file is pgp signed by
-myself:
-

-Key fingerprint = 92 6B F7 58 EE 86 28 C8 C4 1A E6 DC 39 89 F2 AA
-
-Only if the checksums are OK, and the signature of the file
-"drivers/isdn/hisax/md5sums.asc" match, is the certification valid; a
-message confirming this is then displayed during the hisax init process.

-
-
-Configuring the driver
-----------------------
-
-The HiSax driver can either be built directly into the kernel or as a module.
-It can be configured using the command line feature while loading the kernel
-with LILO or LOADLIN or, if built as a module, using insmod/modprobe with
-parameters.
-There is also some config needed before you compile the kernel and/or
-modules. It is included in the normal "make [menu]config" target at the
-kernel. Don't forget it, especially to select the right D-channel protocol.
-
-Please note: In older versions of the HiSax driver, all PnP cards
-needed to be configured with isapnp and worked only with the HiSax
-driver used as a module.
-
-In the current version, HiSax will automatically use the in-kernel
-ISAPnP support, provided you selected it during kernel configuration
-(CONFIG_ISAPNP), if you don't give the io=, irq= command line parameters.
-
-The affected card types are: 4,7,12,14,19,27-30
-
-a) when built as a module
--------------------------
-
-insmod/modprobe hisax.o \
- io=iobase irq=IRQ mem=membase type=card_type \
- protocol=D_channel_protocol id=idstring
-
-or, if several cards are installed:
-
-insmod/modprobe hisax.o \
- io=iobase1,iobase2,... irq=IRQ1,IRQ2,... mem=membase1,membase2,... \
- type=card_type1,card_type2,... \
- protocol=D_channel_protocol1,D_channel_protocol2,... \
- id=idstring1%idstring2 ...
-
-where "iobaseN" represents the I/O base address of the Nth card, "membaseN"
-the memory base address of the Nth card, etc.
-
-The reason for the delimiter "%" being used in the idstrings is that ","
-won't work with the current modules package.
-
-The parameters may be specified in any order. For example, the "io"
-parameter may precede the "irq" parameter, or vice versa. If several
-cards are installed, the ordering within the comma separated parameter
-lists must of course be consistent.
-
-Only parameters applicable to the card type need to be specified. For
-example, the Teles 16.3 card is not memory-mapped, so the "mem"
-parameter may be omitted for this card. Sometimes it may be necessary
-to specify a dummy parameter, however. This is the case when there is
-a card of a different type later in the list that needs a parameter
-which the preceding card does not. For instance, if a Teles 16.0 card
-is listed after a Teles 16.3 card, a dummy memory base parameter of 0
-must be specified for the 16.3. Instead of a dummy value, the parameter
-can also be skipped by simply omitting the value. For example:
-mem=,0xd0000. See example 6 below.
-
-The parameter for the D-Channel protocol may be omitted if you selected the
-correct one during kernel config. Valid values are "1" for German 1TR6,
-"2" for EDSS1 (Euro ISDN), "3" for leased lines (no D-Channel) and "4"
-for US NI1.
-With US NI1 you have to include your SPID into the MSN setting in the form
-<MSN>:<SPID> for example (your phonenumber is 1234 your SPID 5678):
-AT&E1234:5678 on ttyI interfaces
-isdnctrl eaz ippp0 1234:5678 on network devices
-
-The Creatix/Teles PnP cards use io1= and io2= instead of io= for specifying
-the I/O addresses of the ISAC and HSCX chips, respectively.
-
-Card types:
-
- Type Required parameters (in addition to type and protocol)

-
-2. Teles 16.0, 1TR6 ISDN, I/O base d80 hex, IRQ 5, Memory d0000 hex
- modprobe hisax protocol=1 type=1 io=0xd80 mem=0xd0000 irq=5
-
-3. Fritzcard, Euro ISDN, I/O base 340 hex, IRQ 10 and ELSA PCF, Euro ISDN
- modprobe hisax type=5,6 protocol=2,2 io=0x340 irq=10 id=Fritz%Elsa
-
-4. Any ELSA PCC/PCF card, Euro ISDN
- modprobe hisax type=6 protocol=2
-
-5. Teles 16.3 PnP, Euro ISDN, with isapnp configured
- isapnp config: (INT 0 (IRQ 10 (MODE +E)))
- (IO 0 (BASE 0x0580))
- (IO 1 (BASE 0x0180))
- modprobe hisax type=4 protocol=2 irq=10 io0=0x580 io1=0x180
-
- In the current version of HiSax, you can instead simply use
-
- modprobe hisax type=4 protocol=2
-
- if you configured your kernel for ISAPnP. Don't run isapnp in
- this case!
-
-6. Teles 16.3, Euro ISDN, I/O base 280 hex, IRQ 12 and
- Teles 16.0, 1TR6, IRQ 5, Memory d0000 hex
- modprobe hisax type=3,1 protocol=2,1 io=0x280 mem=0,0xd0000
-
- Please note the dummy 0 memory address for the Teles 16.3, used as a
- placeholder as described above, in the last example.

-Running the driver
-------------------
-
-When you insmod isdn.o and hisax.o (or with the in-kernel version, during
-boot time), a few lines should appear in your syslog. Look for something like:
-
-Apr 13 21:01:59 kke01 kernel: HiSax: Driver for Siemens chip set ISDN cards
-Apr 13 21:01:59 kke01 kernel: HiSax: Version 2.9
-Apr 13 21:01:59 kke01 kernel: HiSax: Revisions 1.14/1.9/1.10/1.25/1.8
-Apr 13 21:01:59 kke01 kernel: HiSax: Total 1 card defined
-Apr 13 21:01:59 kke01 kernel: HiSax: Card 1 Protocol EDSS1 Id=HiSax1 (0)
-Apr 13 21:01:59 kke01 kernel: HiSax: Elsa driver Rev. 1.13
-...
-Apr 13 21:01:59 kke01 kernel: Elsa: PCF-Pro found at 0x360 Rev.:C IRQ 10
-Apr 13 21:01:59 kke01 kernel: Elsa: timer OK; resetting card
-Apr 13 21:01:59 kke01 kernel: Elsa: HSCX version A: V2.1 B: V2.1
-Apr 13 21:01:59 kke01 kernel: Elsa: ISAC 2086/2186 V1.1
-...
-Apr 13 21:01:59 kke01 kernel: HiSax: DSS1 Rev. 1.14
-Apr 13 21:01:59 kke01 kernel: HiSax: 2 channels added
-
-This means that the card is ready for use.
-Cabling problems or line-downs are not detected, and only some ELSA cards can
-detect the S0 power.
-
-Remember that, according to the new strategy for accessing low-level drivers
-from within isdn4linux, you should also define a driver ID while doing
-insmod: Simply append hisax_id=<SomeString> to the insmod command line. This
-string MUST NOT start with a digit or a small 'x'!
-
-At this point you can run a 'cat /dev/isdnctrl0' and view debugging messages.
-
-At the moment, debugging messages are enabled with the hisaxctrl tool:
-
- hisaxctrl <DriverId> DebugCmd <debugging_flags>
-
-<DriverId> default is HiSax, if you didn't specify one.
-
-DebugCmd is 1 for generic debugging
- 11 for layer 1 development debugging
- 13 for layer 3 development debugging
-
-where <debugging_flags> is the integer sum of the following debugging
-options you wish enabled:
-
-With DebugCmd set to 1:
-
- 0x0001 Link-level <--> hardware-level communication
- 0x0002 Top state machine
- 0x0004 D-Channel Frames for isdnlog
- 0x0008 D-Channel Q.921
- 0x0010 B-Channel X.75
- 0x0020 D-Channel l2
- 0x0040 B-Channel l2
- 0x0080 D-Channel link state debugging
- 0x0100 B-Channel link state debugging
- 0x0200 TEI debug
- 0x0400 LOCK debug in callc.c
- 0x0800 More paranoid debug in callc.c (not for normal use)
- 0x1000 D-Channel l1 state debugging
- 0x2000 B-Channel l1 state debugging
-
-With DebugCmd set to 11:
-
- 0x0001 Warnings (default: on)
- 0x0002 IRQ status
- 0x0004 ISAC
- 0x0008 ISAC FIFO
- 0x0010 HSCX
- 0x0020 HSCX FIFO (attention: full B-Channel output!)
- 0x0040 D-Channel LAPD frame types
- 0x0080 IPAC debug
- 0x0100 HFC receive debug
- 0x0200 ISAC monitor debug
- 0x0400 D-Channel frames for isdnlog (set with 1 0x4 too)
- 0x0800 D-Channel message verbose
-
-With DebugCmd set to 13:
-
- 1 Warnings (default: on)
- 2 l3 protocol descriptor errors
- 4 l3 state machine
- 8 charge info debugging (1TR6)
-
-For example, 'hisaxctrl HiSax 1 0x3ff' enables full generic debugging.
-
-Because of some obscure problems with some switch equipment, the delay
-between the CONNECT message and sending the first data on the B-channel is now
-configurable with
-
-hisaxctrl <DriverId> 2 <delay>
-<delay> in ms Value between 50 and 800 ms is recommended.
-
-Downloading Firmware
---------------------
-At the moment, the Sedlbauer speed fax+ is the only card, which
-needs to download firmware.
-The firmware is downloaded with the hisaxctrl tool:
-
- hisaxctrl <DriverId> 9 <firmware_filename>
-
-<DriverId> default is HiSax, if you didn't specify one,
-
-where <firmware_filename> is the filename of the firmware file.
-
-For example, 'hisaxctrl HiSax 9 ISAR.BIN' downloads the firmware for
-ISAR based cards (like the Sedlbauer speed fax+).
-
-Warning
--------
-HiSax is a work in progress and may crash your machine.
-For certification look at HiSax.cert file.
-
-Limitations
------------
-At this time, HiSax only works on Euro ISDN lines and German 1TR6 lines.
-For leased lines see appendix.
-
-Bugs
-----
-If you find any, please let me know.

-Appendix: Teles PCMCIA driver
------------------------------
-
-See
- http://www.linux.no/teles_cs.txt
-for instructions.
-
-Appendix: Linux and ISDN-leased lines
--------------------------------------
-
-Original from Juergen Quade, new version KKe.
-
-Attention NEW VERSION, the old leased line syntax won't work !!!
-
-You can use HiSax to connect your Linux-Box via an ISDN leased line
-to e.g. the Internet:
-
-1. Build a kernel which includes the HiSax driver either as a module
- or as part of the kernel.
- cd /usr/src/linux
- make menuconfig
- <ISDN subsystem - ISDN support -- HiSax>
- make clean; make zImage; make modules; make modules_install
-2. Install the new kernel
- cp /usr/src/linux/arch/x86/boot/zImage /etc/kernel/linux.isdn
- vi /etc/lilo.conf
- <add new kernel in the bootable image section>
- lilo
-3. in case the hisax driver is a "fixed" part of the kernel, configure
- the driver with lilo:
- vi /etc/lilo.conf
- <add HiSax driver parameter in the global section (see below)>
- lilo
- Your lilo.conf _might_ look like the following:
-
- # LILO configuration-file
- # global section
- # teles 16.0 on IRQ=5, MEM=0xd8000, PORT=0xd80
- append="hisax=1,3,5,0xd8000,0xd80,HiSax"
- # teles 16.3 (non pnp) on IRQ=15, PORT=0xd80
- # append="hisax=3,3,5,0xd8000,0xd80,HiSax"
- boot=/dev/sda
- compact # faster, but won't work on all systems.
- linear
- read-only
- prompt
- timeout=100
- vga = normal # force sane state
- # Linux bootable partition config begins
- image = /etc/kernel/linux.isdn
- root = /dev/sda1
- label = linux.isdn
- #
- image = /etc/kernel/linux-2.0.30
- root = /dev/sda1
- label = linux.secure
-
- In the line starting with "append" you have to adapt the parameters
- according to your card (see above in this file)
-
-3. boot the new linux.isdn kernel
-4. start the ISDN subsystem:
- a) load - if necessary - the modules (depends, whether you compiled
- the ISDN driver as module or not)
- According to the type of card you have to specify the necessary
- driver parameter (irq, io, mem, type, protocol).
- For the leased line the protocol is "3". See the table above for
- the parameters, which you have to specify depending on your card.
- b) configure i4l
- /sbin/isdnctrl addif isdn0
- # EAZ 1 -- B1 channel 2 --B2 channel
- /sbin/isdnctrl eaz isdn0 1
- /sbin/isdnctrl secure isdn0 on
- /sbin/isdnctrl huptimeout isdn0 0
- /sbin/isdnctrl l2_prot isdn0 hdlc
- # Attention you must not set an outgoing number !!! This won't work !!!
- # The incoming number is LEASED0 for the first card, LEASED1 for the
- # second and so on.
- /sbin/isdnctrl addphone isdn0 in LEASED0
- # Here is no need to bind the channel.
- c) in case the remote partner is a CISCO:
- /sbin/isdnctrl encap isdn0 cisco-h
- d) configure the interface
- /sbin/ifconfig isdn0 ${LOCAL_IP} pointopoint ${REMOTE_IP}
- e) set the routes
- /sbin/route add -host ${REMOTE_IP} isdn0
- /sbin/route add default gw ${REMOTE_IP}
- f) switch the card into leased mode for each used B-channel
- /sbin/hisaxctrl HiSax 5 1
-
-Remarks:
-a) Use state of the art isdn4k-utils
-
-Here an example script:
-#!/bin/sh

- *
- * gerdes_amd7930.c Amd 79C30A and 79C32A specific routines
- * (based on HiSax driver by Karsten Keil)
- *
- * Author Christoph Ersfeld <info@formula-n.de>
- * Formula-n Europe AG (www.formula-n.com)
- * previously Gerdes AG
- *
- *
- * This file is (c) under GNU PUBLIC LICENSE
- *
- *
- * Notes:
- * Version 0.99 is the first release of this driver and there are
- * certainly a few bugs.
- *
- * Please don't report any malfunction to me without sending
- * (compressed) debug-logs.
- * It would be nearly impossible to retrace it.
- *
- * Log D-channel-processing as follows:
- *
- * 1. Load hisax with card-specific parameters, this example ist for
- * Formula-n enter:now ISDN PCI and compatible
- * (f.e. Gerdes Power ISDN PCI)
- *
- * modprobe hisax type=41 protocol=2 id=gerdes
- *
- * if you chose an other value for id, you need to modify the
- * code below, too.
- *
- * 2. set debug-level
- *
- * hisaxctrl gerdes 1 0x3ff
- * hisaxctrl gerdes 11 0x4f
- * cat /dev/isdnctrl >> ~/log &
- *
- * Please take also a look into /var/log/messages if there is
- * anything importand concerning HISAX.
- *
- *
- * Credits:
- * Programming the driver for Formula-n enter:now ISDN PCI and
- * necessary this driver for the used Amd 7930 D-channel-controller
- * was spnsored by Formula-n Europe AG.
- * Thanks to Karsten Keil and Petr Novak, who gave me support in
- * Hisax-specific questions.
- * I want so say special thanks to Carl-Friedrich Braun, who had to
- * answer a lot of questions about generally ISDN and about handling
- * of the Amd-Chip.

-/* enternow_pci.c,v 0.99 2001/10/02
- *
- * enternow_pci.c Card-specific routines for
- * Formula-n enter:now ISDN PCI ab
- * Gerdes AG Power ISDN PCI
- * Woerltronic SA 16 PCI
- * (based on HiSax driver by Karsten Keil)
- *
- * Author Christoph Ersfeld <info@formula-n.de>
- * Formula-n Europe AG (www.formula-n.com)
- * previously Gerdes AG
- *
- *
- * This file is (c) under GNU PUBLIC LICENSE
- *
- * Notes:
- * This driver interfaces to netjet.c which performs B-channel
- * processing.
- *
- * Version 0.99 is the first release of this driver and there are
- * certainly a few bugs.
- * It isn't testet on linux 2.4 yet, so consider this code to be
- * beta.
- *
- * Please don't report me any malfunction without sending
- * (compressed) debug-logs.
- * It would be nearly impossible to retrace it.
- *
- * Log D-channel-processing as follows:
- *
- * 1. Load hisax with card-specific parameters, this example ist for
- * Formula-n enter:now ISDN PCI and compatible
- * (f.e. Gerdes Power ISDN PCI)
- *
- * modprobe hisax type=41 protocol=2 id=gerdes
- *
- * if you chose an other value for id, you need to modify the
- * code below, too.
- *
- * 2. set debug-level
- *
- * hisaxctrl gerdes 1 0x3ff
- * hisaxctrl gerdes 11 0x4f
- * cat /dev/isdnctrl >> ~/log &
- *
- * Please take also a look into /var/log/messages if there is
- * anything importand concerning HISAX.
- *
- *
- * Credits:
- * Programming the driver for Formula-n enter:now ISDN PCI and
- * necessary the driver for the used Amd 7930 D-channel-controller
- * was spnsored by Formula-n Europe AG.
- * Thanks to Karsten Keil and Petr Novak, who gave me support in
- * Hisax-specific questions.
- * I want so say special thanks to Carl-Friedrich Braun, who had to
- * answer a lot of questions about generally ISDN and about handling
- * of the Amd-Chip.
