Linux-2.6.12-rc2v2.6.12-rc2

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!

+HiSax is a Linux hardware-level driver for passive ISDN cards with Siemens
+chipset (ISAC_S 2085/2086/2186, HSCX SAB 82525). It is based on the Teles
+driver from Jan den Ouden.
+It is meant to be used with isdn4linux, an ISDN link-level module for Linux
+written by Fritz Elfert.

+(io, mem, irq).
+
+
+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.

+
+    Type                Required parameters (in addition to type and protocol)

+Examples for module loading
+
+1. Teles 16.3, Euro ISDN, I/O base 280 hex, IRQ 10
+   modprobe hisax type=3 protocol=2 io=0x280 irq=10
+
+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.
+
+7. Teles PCMCIA, Euro ISDN, I/O base 180 hex, IRQ 15 (default values)
+   modprobe hisax type=8 protocol=2 io=0x180 irq=15

+
+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: 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.

+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/i386/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
+# Start/Stop ISDN leased line connection
+
