+* Rules to follow when using local atomic operations
+
+- Variables touched by local ops must be per cpu variables.
+- _Only_ the CPU owner of these variables must write to them.
+- This CPU can use local ops from any context (process, irq, softirq, nmi, ...)
+ to update its local_t variables.
+- Preemption (or interrupts) must be disabled when using local ops in
+ process context to make sure the process won't be migrated to a
+ different CPU between getting the per-cpu variable and doing the
+ actual local op.
+- When using local ops in interrupt context, no special care must be
+ taken on a mainline kernel, since they will run on the local CPU with
+ preemption already disabled. I suggest, however, to explicitly
+ disable preemption anyway to make sure it will still work correctly on
+ -rt kernels.
+- Reading the local cpu variable will provide the current copy of the
+ variable.
+- Reads of these variables can be done from any CPU, because updates to
+ "long", aligned, variables are always atomic. Since no memory
+ synchronization is done by the writer CPU, an outdated copy of the
+ variable can be read when reading some _other_ cpu's variables.

-There are a few network parameters that can be tuned to better match
-the kernel to your system hardware and intended usage. The defaults
-are usually a good choice for 99% of the people 99% of the time, but
-you should be aware they do exist and can be changed.
-
-The current list of parameters can be found in the files:
-
- linux/net/TUNABLE
- Documentation/networking/ip-sysctl.txt
-
-Some of these are accessible via the sysctl interface, and many more are
-scheduled to be added in this way. For example, some parameters related
-to Address Resolution Protocol (ARP) are very easily viewed and altered.
-
- # cat /proc/sys/net/ipv4/arp_timeout
- 6000
- # echo 7000 > /proc/sys/net/ipv4/arp_timeout
- # cat /proc/sys/net/ipv4/arp_timeout
- 7000
-
-Others are already accessible via the related user space programs.
-For example, MAX_WINDOW has a default of 32 k which is a good choice for
-modern hardware, but if you have a slow (8 bit) Ethernet card and/or a slow
-machine, then this will be far too big for the card to keep up with fast
-machines transmitting on the same net, resulting in overruns and receive errors.
-A value of about 4 k would be more appropriate, which can be set via:
-
- # route add -net 192.168.3.0 window 4096
-
-The remainder of these can only be presently changed by altering a #define
-in the related header file. This means an edit and recompile cycle.

- COMX drivers for the 2.2 kernel
-
-Originally written by: Tivadar Szemethy, <tiv@itc.hu>
-Currently maintained by: Gergely Madarasz <gorgo@itc.hu>
-
-Last change: 21/06/1999.
-
-INTRODUCTION
-
-This document describes the software drivers and their use for the
-COMX line of synchronous serial adapters for Linux version 2.2.0 and
-above.
-The cards are produced and sold by ITC-Pro Ltd. Budapest, Hungary
-For further info contact <info@itc.hu>
-or http://www.itc.hu (mostly in Hungarian).
-The firmware files and software are available from ftp://ftp.itc.hu
-
-Currently, the drivers support the following cards and protocols:
-
-COMX (2x64 kbps intelligent board)
-CMX (1x256 + 1x128 kbps intelligent board)
-HiCOMX (2x2Mbps intelligent board)
-LoCOMX (1x512 kbps passive board)
-MixCOM (1x512 or 2x512kbps passive board with a hardware watchdog an
- optional BRI interface and optional flashROM (1-32M))
-SliceCOM (1x2Mbps channelized E1 board)
-PciCOM (X21)
-
-At the moment of writing this document, the (Cisco)-HDLC, LAPB, SyncPPP and
-Frame Relay (DTE, rfc1294 IP encapsulation with partially implemented Q933a
-LMI) protocols are available as link-level protocol.
-X.25 support is being worked on.
-
-USAGE
-
-Load the comx.o module and the hardware-specific and protocol-specific
-modules you'll need into the running kernel using the insmod utility.
-This creates the /proc/comx directory.
-See the example scripts in the 'etc' directory.
-
-/proc INTERFACE INTRO
-
-The COMX driver set has a new type of user interface based on the /proc
-filesystem which eliminates the need for external user-land software doing
-IOCTL calls.
-Each network interface or device (i.e. those ones you configure with 'ifconfig'
-and 'route' etc.) has a corresponding directory under /proc/comx. You can
-dynamically create a new interface by saying 'mkdir /proc/comx/comx0' (or you
-can name it whatever you want up to 8 characters long, comx[n] is just a
-convention).
-Generally the files contained in these directories are text files, which can
-be viewed by 'cat filename' and you can write a string to such a file by
-saying 'echo _string_ >filename'. This is very similar to the sysctl interface.
-Don't use a text editor to edit these files, always use 'echo' (or 'cat'
-where appropriate).
-When you've created the comx[n] directory, two files are created automagically
-in it: 'boardtype' and 'protocol'. You have to fill in these files correctly
-for your board and protocol you intend to use (see the board and protocol
-descriptions in this file below or the example scripts in the 'etc' directory).
-After filling in these files, other files will appear in the directory for
-setting the various hardware- and protocol-related informations (for example
-irq and io addresses, keepalive values etc.) These files are set to default
-values upon creation, so you don't necessarily have to change all of them.
-
-When you're ready with filling in the files in the comx[n] directory, you can
-configure the corresponding network interface with the standard network
-configuration utilities. If you're unable to bring the interfaces up, look up
-the various kernel log files on your system, and consult the messages for
-a probable reason.
-
-EXAMPLE
-
-To create the interface 'comx0' which is the first channel of a COMX card:
-
-insmod comx
-# insmod comx-hw-comx ; insmod comx-proto-ppp (these are usually
-autoloaded if you use the kernel module loader)
-
-mkdir /proc/comx/comx0
-echo comx >/proc/comx/comx0/boardtype
-echo 0x360 >/proc/comx/comx0/io <- jumper-selectable I/O port
-echo 0x0a >/proc/comx/comx0/irq <- jumper-selectable IRQ line
-echo 0xd000 >/proc/comx/comx0/memaddr <- software-configurable memory
- address. COMX uses 64 KB, and this
- can be: 0xa000, 0xb000, 0xc000,
- 0xd000, 0xe000. Avoid conflicts
- with other hardware.
-cat </etc/siol1.rom >/proc/comx/comx0/firmware <- the firmware for the card
-echo HDLC >/proc/comx/comx0/protocol <- the data-link protocol
-echo 10 >/proc/comx/comx0/keepalive <- the keepalive for the protocol
-ifconfig comx0 1.2.3.4 pointopoint 5.6.7.8 netmask 255.255.255.255 <-
- finally configure it with ifconfig
-Check its status:
-cat /proc/comx/comx0/status
-
-If you want to use the second channel of this board:
-
-mkdir /proc/comx/comx1
-echo comx >/proc/comx/comx1/boardtype
-echo 0x360 >/proc/comx/comx1/io
-echo 10 >/proc/comx/comx1/irq
-echo 0xd000 >/proc/comx/comx1/memaddr
-echo 1 >/proc/comx/comx1/channel <- channels are numbered
- as 0 (default) and 1
-
-Now, check if the driver recognized that you're going to use the other
-channel of the same adapter:
-
-cat /proc/comx/comx0/twin
-comx1
-cat /proc/comx/comx1/twin
-comx0
-
-You don't have to load the firmware twice, if you use both channels of
-an adapter, just write it into the channel 0's /proc firmware file.
-
-Default values: io 0x360 for COMX, 0x320 (HICOMX), irq 10, memaddr 0xd0000
-
-THE LOCOMX HARDWARE DRIVER
-
-The LoCOMX driver doesn't require firmware, and it doesn't use memory either,
-but it uses DMA channels 1 and 3. You can set the clock rate (if enabled by
-jumpers on the board) by writing the kbps value into the file named 'clock'.
-Set it to 'external' (it is the default) if you have external clock source.
-
-(Note: currently the LoCOMX driver does not support the internal clock)
-
-THE COMX, CMX AND HICOMX DRIVERS
-
-On the HICOMX, COMX and CMX, you have to load the firmware (it is different for
-the three cards!). All these adapters can share the same memory
-address (we usually use 0xd0000). On the CMX you can set the internal
-clock rate (if enabled by jumpers on the small adapter boards) by writing
-the kbps value into the 'clock' file. You have to do this before initializing
-the card. If you use both HICOMX and CMX/COMX cards, initialize the HICOMX
-first. The I/O address of the HICOMX board is not configurable by any
-method available to the user: it is hardwired to 0x320, and if you have to
-change it, consult ITC-Pro Ltd.
-
-THE MIXCOM DRIVER
-
-The MixCOM board doesn't require firmware, the driver communicates with
-it through I/O ports. You can have three of these cards in one machine.
-
-THE SLICECOM DRIVER
-
-The SliceCOM board doesn't require firmware. You can have 4 of these cards
-in one machine. The driver doesn't (yet) support shared interrupts, so
-you will need a separate IRQ line for every board.
-Read Documentation/networking/slicecom.txt for help on configuring
-this adapter.
-
-THE HDLC/PPP LINE PROTOCOL DRIVER
-
-The HDLC/SyncPPP line protocol driver uses the kernel's built-in syncppp
-driver (syncppp.o). You don't have to manually select syncppp.o when building
-the kernel, the dependencies compile it in automatically.
-
-
-
-
-EXAMPLE
-(setting up hw parameters, see above)
-
-# using HDLC:
-echo hdlc >/proc/comx/comx0/protocol
-echo 10 >/proc/comx/comx0/keepalive <- not necessary, 10 is the default
-ifconfig comx0 1.2.3.4 pointopoint 5.6.7.8 netmask 255.255.255.255
-
-(setting up hw parameters, see above)
-
-# using PPP:
-echo ppp >/proc/comx/comx0/protocol
-ifconfig comx0 up
-ifconfig comx0 1.2.3.4 pointopoint 5.6.7.8 netmask 255.255.255.255
-
-
-THE LAPB LINE PROTOCOL DRIVER
-
-For this, you'll need to configure LAPB support (See 'LAPB Data Link Driver' in
-'Network options' section) into your kernel (thanks to Jonathan Naylor for his
-excellent implementation).
-comx-proto-lapb.o provides the following files in the appropriate directory
-(the default values in parens): t1 (5), t2 (1), n2 (20), mode (DTE, STD) and
-window (7). Agree with the administrator of your peer router on these
-settings (most people use defaults, but you have to know if you are DTE or
-DCE).
-
-EXAMPLE
-
-(setting up hw parameters, see above)
-echo lapb >/proc/comx/comx0/protocol
-echo dce >/proc/comx/comx0/mode <- DCE interface in this example
-ifconfig comx0 1.2.3.4 pointopoint 5.6.7.8 netmask 255.255.255.255
-
-
-THE FRAME RELAY PROTOCOL DRIVER
-
-You DON'T need any other frame relay related modules from the kernel to use
-COMX-Frame Relay. This protocol is a bit more complicated than the others,
-because it allows to use 'subinterfaces' or DLCIs within one physical device.
-First you have to create the 'master' device (the actual physical interface)
-as you would do for other protocols. Specify 'frad' as protocol type.
-Now you can bring this interface up by saying 'ifconfig comx0 up' (or whatever
-you've named the interface). Do not assign any IP address to this interface
-and do not set any routes through it.
-Then, set up your DLCIs the following way: create a comx interface for each
-DLCI you intend to use (with mkdir), and write 'dlci' to the 'boardtype' file,
-and 'ietf-ip' to the 'protocol' file. Currently, the only supported
-encapsulation type is this (also called as RFC1294/1490 IP encapsulation).
-Write the DLCI number to the 'dlci' file, and write the name of the physical
-COMX device to the file called 'master'.
-Now you can assign an IP address to this interface and set routes using it.
-See the example file for further info and example config script.
-Notes: this driver implements a DTE interface with partially implemented
-Q933a LMI.
-You can find an extensively commented example in the 'etc' directory.
-
-FURTHER /proc FILES
-
-boardtype:
-Type of the hardware. Valid values are:
- 'comx', 'hicomx', 'locomx', 'cmx', 'slicecom'.
-
-protocol:
-Data-link protocol on this channel. Can be: HDLC, LAPB, PPP, FRAD
-
-status:
-You can read the channel's actual status from the 'status' file, for example
-'cat /proc/comx/comx3/status'.
-
-lineup_delay:
-Interpreted in seconds (default is 1). Used to avoid line jitter: the system
-will consider the line status 'UP' only if it is up for at least this number
-of seconds.
-
-debug:
-You can set various debug options through this file. Valid options are:
-'comx_events', 'comx_tx', 'comx_rx', 'hw_events', 'hw_tx', 'hw_rx'.
-You can enable a debug options by writing its name prepended by a '+' into
-the debug file, for example 'echo +comx_rx >comx0/debug'.
-Disabling an option happens similarly, use the '-' prefix
-(e.g. 'echo -hw_rx >debug').
-Debug results can be read from the debug file, for example:
-tail -f /proc/comx/comx2/debug

-NCSA telnet doesn't work with path MTU discovery enabled. This is due to a
-bug in NCSA that also stops it working with other modern networking code
-such as Solaris.

-The following information is courtesy of
-Marek <marekm@i17linuxb.ists.pwr.wroc.pl>
-
-There is a fixed version somewhere on ftp.upe.ac.za (sorry, I don't
-remember the exact pathname, and this site is very slow from here).
-It may or may not be faster for you to get it from
-ftp://ftp.ists.pwr.wroc.pl/pub/msdos/telnet/ncsa_upe/tel23074.zip
-(source is in v230704s.zip). I have tested it with 1.3.79 (with
-path mtu discovery enabled - ncsa 2.3.08 didn't work) and it seems
-to work. I don't know if anyone is working on this code - this
-version is over a year old. Too bad - it's faster and often more
-stable than these windoze telnets, and runs on almost anything...

-This is the README for the Gracilis Packetwin device driver, version 0.5
-ALPHA for Linux 1.3.43.
-
-These files will allow you to talk to the PackeTwin (now know as PT) and
-connect through it just like a pair of TNCs. To do this you will also
-require the AX.25 code in the kernel enabled.
-
-There are four files in this archive; this readme, a patch file, a .c file
-and finally a .h file. The two program files need to be put into the
-drivers/net directory in the Linux source tree, for me this is the
-directory /usr/src/linux/drivers/net. The patch file needs to be patched in
-at the top of the Linux source tree (/usr/src/linux in my case).
-
-You will most probably have to edit the pt.c file to suit your own setup,
-this should just involve changing some of the defines at the top of the file.
-Please note that if you run an external modem you must specify a speed of 0.
-
-The program is currently setup to run a 4800 baud external modem on port A
-and a Kantronics DE-9600 daughter board on port B so if you have this (or
-something similar) then you're right.
-
-To compile in the driver, put the files in the correct place and patch in
-the diff. You will have to re-configure the kernel again before you
-recompile it.
-
-The driver is not real good at the moment for finding the card. You can
-'help' it by changing the order of the potential addresses in the structure
-found in the pt_init() function so the address of where the card is is put
-first.
-
-After compiling, you have to get them going, they are pretty well like any
-other net device and just need ifconfig to get them going.
-As an example, here is my /etc/rc.net

-fajlban leirtak SliceCOM kartyanal is ervenyesek, itt csak a hardver-specifikus
-beallitasi lehetosegek vannak osszefoglalva:
-
-Konfiguralasi interfesz a /proc/comx/ alatt:
-
-Minden timeslot-csoportnak kulon comx* interfeszt kell letrehozni mkdir-rel:
-comx0, comx1, .. stb. Itt beallithato, hogy az adott interfesz hanyadik kartya
-melyik timeslotja(i)bol alljon ossze. A Cisco-fele serial3:1 elnevezesek
-(serial3:1 = a 3. kartyaban az 1-es idoszelet-csoport) Linuxon aliasing-ot
-jelentenenek, ezert mi nem tudunk ilyen elnevezest hasznalni.
-
-Tobb kartya eseten a comx0.1, comx0.2, ... vagy slice0.1, slice0.2 nevek
-hasznalhatoak.
-
-Tobb SliceCOM kartya is lehet egy gepben, de sajat interrupt kell mindegyiknek,
-nem tud meg megosztott interruptot kezelni.
-
-Az egesz kartyat erinto beallitasok:
-
-Az ioport es irq beallitas nincs: amit a PCI BIOS kioszt a rendszernek,
-azt hasznalja a driver.
-
-
-comx0/boardnum - hanyadik SliceCOM kartya a gepben (a 'termeszetes' PCI
- sorrendben ertve: ahogyan a /proc/pci-ban vagy az 'lspci'
- kimeneteben megjelenik, altalaban az alaplapi PCI meghajto
- aramkorokhoz kozelebb eso kartyak a kisebb sorszamuak)
-
- Default: 0 (0-tol kezdodik a szamolas)
-
-
-Bar a kovetkezoket csak egy-egy interfeszen allitjuk at, megis az egesz kartya
-mukodeset egyszerre allitjak. A megkotes hogy csak UP-ban levo interfeszen
-hasznalhatoak, azert van, mert kulonben nem vart eredmenyekre vezetne egy ilyen
-paranccsorozat:
-
- echo 0 >boardnum
- echo internal >clock_source
- echo 1 >boardnum
-
-- Ez a 0-s board clock_source-at allitana at.
-
-Ezek a beallitasok megmaradnak az osszes interfesz torlesekor, de torlodnek
-a driver modul ki/betoltesekor.
-
-
-comx0/clock_source - A Tx orajelforrasa, a Cisco-val hasonlatosra keszult.
- Hasznalata:
-
- papaya:# echo line >/proc/comx/comx0/clock_source
- papaya:# echo internal >/proc/comx/comx0/clock_source
-
- line - A Tx orajelet a vett adatfolyambol dekodolja, igyekszik
- igazodni hozza. Ha nem lat orajelet az inputon, akkor
- atall a sajat orajelgeneratorara.
- internal - A Tx orajelet a sajat orajelgeneratora szolgaltatja.
-
- Default: line
-
- Normal osszeallitas eseten a tavkozlesi szolgaltato eszkoze
- (pl. HDSL modem) adja az orajelet, ezert ez a default.
-
-
-comx0/framing - A CRC4 ki/be kapcsolasa
-
- A CRC4: 16 PCM keretet (A PCM keret az, amibe a 32 darab 64
- kilobites csatorna van bemultiplexalva. Nem osszetevesztendo a HDLC
- kerettel.) 2x8 -as csoportokra osztanak, es azokhoz 4-4 bites CRC-t
- szamolnak. Elsosorban a vonal minosegenek a monitorozasara szolgal.
-
- papaya:~# echo crc4 >/proc/comx/comx0/framing
- papaya:~# echo no-crc4 >/proc/comx/comx0/framing
-
- Default a 'crc4', a MATAV vonalak altalaban igy futnak. De ha nem
- egyforma is a beallitas a vonal ket vegen, attol a forgalom altalaban
- at tud menni.
-
-
-comx0/linecode - A vonali kodolas beallitasa
-
- papaya:~# echo hdb3 >/proc/comx/comx0/linecode
- papaya:~# echo ami >/proc/comx/comx0/linecode
-
- Default a 'hdb3', a MATAV vonalak igy futnak.
-
- (az AMI kodolas igen ritka E1-es vonalaknal). Ha ez a beallitas nem
- egyezik a vonal ket vegen, akkor elofordulhat hogy a keretszinkron
- osszejon, de CRC4-hibak es a vonalakon atvitt adatokban is hibak
- keletkeznek (amit a HDLC/SyncPPP szinten CRC-hibaval jelez)
-
-
-comx0/reg - a kartya aramkoreinek, a MUNICH (reg) es a FALC (lbireg)
-comx0/lbireg regisztereinek kozvetlen elerese. Hasznalata:
-
- echo >reg 0x04 0x0 - a 4-es regiszterbe 0-t ir
- echo >reg 0x104 - printk()-val kiirja a 4-es regiszter
- tartalmat a syslogba.
-
- WARNING: ezek csak a fejleszteshez keszultek, sok galibat
- lehet veluk okozni!
-
-
-comx0/loopback - A kartya G.703 jelenek a visszahurkolasara is van lehetoseg:
-
- papaya:# echo none >/proc/comx/comx0/loopback
- papaya:# echo local >/proc/comx/comx0/loopback
- papaya:# echo remote >/proc/comx/comx0/loopback
-
- none - nincs visszahurkolas, normal mukodes
- local - a kartya a sajat maga altal adott jelet kapja vissza
- remote - a kartya a kivulrol vett jelet adja kifele
-
- Default: none
-

-
-Az interfeszhez (Cisco terminologiaban 'channel-group') kapcsolodo beallitasok:
-
-comx0/timeslots - mely timeslotok (idoszeletek) tartoznak az adott interfeszhez.
-
- papaya:~# cat /proc/comx/comx0/timeslots
- 1 3 4 5 6
- papaya:~#
-

- papaya:~#
-
- Beallitasa:
- papaya:~# echo '1 5 2 6 7 8' >/proc/comx/comx0/timeslots
-
- A timeslotok sorrendje nem szamit, '1 3 2' ugyanaz mint az '1 2 3'.
-
- Beallitashoz az adott interfesznek DOWN-ban kell lennie
- (ifconfig comx0 down), de ugyanannak a kartyanak a tobbi interfesze
- uzemelhet kozben.
-
- Beallitaskor leellenorzi, hogy az uj timeslotok nem utkoznek-e egy
- masik interfesz timeslotjaival. Ha utkoznek, akkor nem allitja at.
-
- Mindig 10-es szamrendszerben tortenik a timeslotok ertelmezese, nehogy

-
-Usage:
-
-Compiling the kernel:
-
-Code maturity level options
- [*] Prompt for development and/or incomplete code/drivers
-
-Network device support
- Wan interfaces
- <M> MultiGate (COMX) synchronous
- <M> Support for MUNICH based boards: SliceCOM, PCICOM (NEW)
- <M> Support for HDLC and syncPPP...
-
-
-Loading the modules:
-
-modprobe comx
-
-modprobe comx-proto-ppp # module for Cisco-HDLC and SyncPPP protocols
-
-modprobe comx-hw-munich # the module logs information by the kernel
- # about the detected boards
-
-
-Configuring the board:
-
-# This interface will use the Cisco-HDLC line protocol,
-# the timeslices assigned are 1,2 (128 KiBit line speed)
-# (the first data timeslice in the G.703 frame is no. 1)
-#
-mkdir /proc/comx/comx0.1/
-echo slicecom >/proc/comx/comx0.1/boardtype
-echo hdlc >/proc/comx/comx0.1/protocol
-echo 1 2 >/proc/comx/comx0.1/timeslots
-
-
-# This interface uses SyncPPP line protocol, the assigned
-# is no. 3 (64 KiBit line speed)
-#
-mkdir /proc/comx/comx0.2/
-echo slicecom >/proc/comx/comx0.2/boardtype
-echo ppp >/proc/comx/comx0.2/protocol
-echo 3 >/proc/comx/comx0.2/timeslots
-
-...
-
-ifconfig comx0.1 up
-ifconfig comx0.2 up
-
------------------------------------------------------------------
-
-The COMX interfaces use a 10 packet transmit queue by default, however WAN
-networks sometimes use bigger values (20 to 100), to utilize the line better
-by large traffic (though the line delay increases because of more packets
-join the queue).
-
-# ifconfig comx0 txqueuelen 50
-
-This option is only supported by the ifconfig command of the later
-distributions, which came with 2.2 kernels, such as RedHat 6.1 or Debian 2.2.
-
-You can download a newer netbase packet from
-http://www.debian.org/~rcw/2.2/netbase/ for Debian 2.1, which has a new
-ifconfig. You can get further information about using 2.2 kernel with
-Debian 2.1 from http://www.debian.org/releases/stable/running-kernel-2.2
-
------------------------------------------------------------------
-
-The SliceCom LEDs:
-
-red - on, if the interface is unconfigured, or it gets Remote Alarm-s
-green - on, if the board finds frame-sync in the received signal
-
-A bit more detailed:
-
-red: green: meaning:
-
-- - no frame-sync, no signal received, or signal SNAFU.
-- on "Everything is OK"
-on on Reception is ok, but the remote end sends Remote Alarm
-on - The interface is unconfigured
-
------------------------------------------------------------------
-
-A more detailed description of the hardware setting options:
-
-The general and the protocol layer options described in the 'comx.txt' file
-apply to the SliceCom as well, I only summarize the SliceCom hardware specific
-settings below.
-
-The '/proc/comx' configuring interface:
-
-An interface directory should be created for every timeslot group with
-'mkdir', e,g: 'comx0', 'comx1' etc. The timeslots can be assigned here to the
-specific interface. The Cisco-like naming convention (serial3:1 - first
-timeslot group of the 3rd. board) can't be used here, because these mean IP
-aliasing in Linux.
-
-You can give any meaningful name to keep the configuration clear;
-e.g: 'comx0.1', 'comx0.2', 'comx1.1', comx1.2', if you have two boards
-with two interfaces each.
-
-Settings, which apply to the board:
-
-Neither 'io' nor 'irq' settings required, the driver uses the resources
-given by the PCI BIOS.
-
-comx0/boardnum - board number of the SliceCom in the PC (using the 'natural'
- PCI order) as listed in '/proc/pci' or the output of the
- 'lspci' command, generally the slots nearer to the motherboard
- PCI driver chips have the lower numbers.
-
- Default: 0 (the counting starts with 0)
-
-Though the options below are to be set on a single interface, they apply to the
-whole board. The restriction, to use them on 'UP' interfaces, is because the
-command sequence below could lead to unpredictable results.
-
- # echo 0 >boardnum
- # echo internal >clock_source
- # echo 1 >boardnum
-
-The sequence would set the clock source of board 0.
-
-These settings will persist after all the interfaces are cleared, but are
-cleared when the driver module is unloaded and loaded again.
-
-comx0/clock_source - source of the transmit clock
- Usage:
-
- # echo line >/proc/comx/comx0/clock_source
- # echo internal >/proc/comx/comx0/clock_source
-
- line - The Tx clock is being decoded if the input data stream,
- if no clock seen on the input, then the board will use it's
- own clock generator.
-
- internal - The Tx clock is supplied by the builtin clock generator.
-
- Default: line
-
- Normally, the telecommunication company's end device (the HDSL
- modem) provides the Tx clock, that's why 'line' is the default.
-
-comx0/framing - Switching CRC4 off/on
-
- CRC4: 16 PCM frames (The 32 64Kibit channels are multiplexed into a
- PCM frame, nothing to do with HDLC frames) are divided into 2x8
- groups, each group has a 4 bit CRC.
-
- # echo crc4 >/proc/comx/comx0/framing
- # echo no-crc4 >/proc/comx/comx0/framing
-
- Default is 'crc4', the Hungarian MATAV lines behave like this.
- The traffic generally passes if this setting on both ends don't match.
-
-comx0/linecode - Setting the line coding
-
- # echo hdb3 >/proc/comx/comx0/linecode
- # echo ami >/proc/comx/comx0/linecode
-
- Default a 'hdb3', MATAV lines use this.
-
- (AMI coding is rarely used with E1 lines). Frame sync may occur, if
- this setting doesn't match the other end's, but CRC4 and data errors
- will come, which will result in CRC errors on HDLC/SyncPPP level.
-
-comx0/reg - direct access to the board's MUNICH (reg) and FALC (lbireg)
-comx0/lbireg circuit's registers
-
- # echo >reg 0x04 0x0 - write 0 to register 4
- # echo >reg 0x104 - write the contents of register 4 with
- printk() to syslog
-
-WARNING! These are only for development purposes, messing with this will
- result much trouble!
-
-comx0/loopback - Places a loop to the board's G.703 signals
-
- # echo none >/proc/comx/comx0/loopback
- # echo local >/proc/comx/comx0/loopback
- # echo remote >/proc/comx/comx0/loopback
-
- none - normal operation, no loop
- local - the board receives it's own output
- remote - the board sends the received data to the remote side
-
- Default: none
-
------------------------------------------------------------------
-
-Interface (channel group in Cisco terms) settings:
-
-comx0/timeslots - which timeslots belong to the given interface
-
- Setting:
-
- # echo '1 5 2 6 7 8' >/proc/comx/comx0/timeslots
-
- # cat /proc/comx/comx0/timeslots
- 1 2 5 6 7 8
- #
-
- Finding a timeslot:
-
- # grep ' 4' /proc/comx/comx*/timeslots
- /proc/comx/comx0/timeslots:1 3 4 5 6
- #
-
- The timeslots can be in any order, '1 2 3' is the same as '1 3 2'.
-
- The interface has to be DOWN during the setting ('ifconfig comx0
- down'), but the other interfaces could operate normally.
-
- The driver checks if the assigned timeslots are vacant, if not, then
- the setting won't be applied.
-
- The timeslot values are treated as decimal numbers, not to misunderstand
- values of 08, 09 form.

-
-Some unique options, (may get into the driver later):
-Treat them very carefully, these can cause much trouble!
-
- modified CRC-4, for improved interworking of CRC-4 and non-CRC-4
- devices: (see page 107 and g706 Annex B)
- lbireg[ 0x1b ] |= 0x08
- lbireg[ 0x1c ] |= 0xc0
-
- - The NMF - 'No Multiframe alignment Found after 400 msec' alarm
- comes into account.
-
- FALC - the line driver chip.
- local loop - I hear my transmission back.
- remote loop - I echo the remote transmission back.
-
- Something useful for finding errors:
-
- - local loop for timeslot 1 in the FALC chip:
-
- # echo >lbireg 0x1d 0x21
-
- - Switching the loop off:
-
- # echo >lbireg 0x1d 0x00

+ This setting is irrelevant for most IDE disks, with direct memory

+ mode is a feature of most modern IDE hard drives, permitting the

+ rather than the usual one sector per interrupt. When this feature is
+ enabled, it can reduce operating system overhead for disk Programmed
