+- This CPU can use local ops from any context (process, irq, softirq, nmi, ...)

+- Preemption (or interrupts) must be disabled when using local ops in

+- When using local ops in interrupt context, no special care must be

+- 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

-There are a few network parameters that can be tuned to better match

-
-The current list of parameters can be found in the files:

- 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

-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

- TOS and incoming interface.
-- Complete set of IP level control messages.
- Now Linux is the only OS in the world complying to RFC requirements.
- Great win 8)
-- New interface addressing paradigm.
- Assignment of address ranges to interface,

-- "Abstract" UNIX sockets and security enhancements.
- This is necessary to use TIRPC and TLI emulation library.

-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)

-
-
-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

- 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)

-
- A timeslotok sorrendje nem szamit, '1 3 2' ugyanaz mint az '1 2 3'.
-
- Beallitashoz az adott interfesznek DOWN-ban kell lennie

-
-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

For Axon: 0x0000012a
+ l) Xilinx IP cores
+
+ The Xilinx EDK toolchain ships with a set of IP cores (devices) for use
+ in Xilinx Spartan and Virtex FPGAs. The devices cover the whole range
+ of standard device types (network, serial, etc.) and miscellanious
+ devices (gpio, LCD, spi, etc). Also, since these devices are
+ implemented within the fpga fabric every instance of the device can be
+ synthesised with different options that change the behaviour.
+
+ Each IP-core has a set of parameters which the FPGA designer can use to
+ control how the core is synthesized. Historically, the EDK tool would
+ extract the device parameters relevant to device drivers and copy them
+ into an 'xparameters.h' in the form of #define symbols. This tells the
+ device drivers how the IP cores are configured, but it requres the kernel
+ to be recompiled every time the FPGA bitstream is resynthesized.
+
+ The new approach is to export the parameters into the device tree and
+ generate a new device tree each time the FPGA bitstream changes. The
+ parameters which used to be exported as #defines will now become
+ properties of the device node. In general, device nodes for IP-cores
+ will take the following form:
+
+ (name)@(base-address) {
+ compatible = "xlnx,(ip-core-name)-(HW_VER)"
+ [, (list of compatible devices), ...];
+ reg = <(baseaddr) (size)>;
+ interrupt-parent = <&interrupt-controller-phandle>;
+ interrupts = < ... >;
+ xlnx,(parameter1) = "(string-value)";
+ xlnx,(parameter2) = <(int-value)>;
+ };
+
+ (ip-core-name): the name of the ip block (given after the BEGIN
+ directive in system.mhs). Should be in lowercase
+ and all underscores '_' converted to dashes '-'.
+ (name): is derived from the "PARAMETER INSTANCE" value.
+ (parameter#): C_* parameters from system.mhs. The C_ prefix is
+ dropped from the parameter name, the name is converted
+ to lowercase and all underscore '_' characters are
+ converted to dashes '-'.
+ (baseaddr): the C_BASEADDR parameter.
+ (HW_VER): from the HW_VER parameter.
+ (size): equals C_HIGHADDR - C_BASEADDR + 1
+
+ Typically, the compatible list will include the exact IP core version
+ followed by an older IP core version which implements the same
+ interface or any other device with the same interface.
+
+ 'reg', 'interrupt-parent' and 'interrupts' are all optional properties.
+
+ For example, the following block from system.mhs:
+
+ BEGIN opb_uartlite
+ PARAMETER INSTANCE = opb_uartlite_0
+ PARAMETER HW_VER = 1.00.b
+ PARAMETER C_BAUDRATE = 115200
+ PARAMETER C_DATA_BITS = 8
+ PARAMETER C_ODD_PARITY = 0
+ PARAMETER C_USE_PARITY = 0
+ PARAMETER C_CLK_FREQ = 50000000
+ PARAMETER C_BASEADDR = 0xEC100000
+ PARAMETER C_HIGHADDR = 0xEC10FFFF
+ BUS_INTERFACE SOPB = opb_7
+ PORT OPB_Clk = CLK_50MHz
+ PORT Interrupt = opb_uartlite_0_Interrupt
+ PORT RX = opb_uartlite_0_RX
+ PORT TX = opb_uartlite_0_TX
+ PORT OPB_Rst = sys_bus_reset_0
+ END
+
+ becomes the following device tree node:
+
+ opb-uartlite-0@ec100000 {
+ device_type = "serial";
+ compatible = "xlnx,opb-uartlite-1.00.b";
+ reg = <ec100000 10000>;
+ interrupt-parent = <&opb-intc>;
+ interrupts = <1 0>; // got this from the opb_intc parameters
+ current-speed = <d#115200>; // standard serial device prop
+ clock-frequency = <d#50000000>; // standard serial device prop
+ xlnx,data-bits = <8>;
+ xlnx,odd-parity = <0>;
+ xlnx,use-parity = <0>;
+ };
+
+ Some IP cores actually implement 2 or more logical devices. In this case,
+ the device should still describe the whole IP core with a single node
+ and add a child node for each logical device. The ranges property can
+ be used to translate from parent IP-core to the registers of each device.
+ (Note: this makes the assumption that both logical devices have the same
+ bus binding. If this is not true, then separate nodes should be used for
+ each logical device). The 'cell-index' property can be used to enumerate
+ logical devices within an IP core. For example, the following is the
+ system.mhs entry for the dual ps2 controller found on the ml403 reference
+ design.
+
+ BEGIN opb_ps2_dual_ref
+ PARAMETER INSTANCE = opb_ps2_dual_ref_0
+ PARAMETER HW_VER = 1.00.a
+ PARAMETER C_BASEADDR = 0xA9000000
+ PARAMETER C_HIGHADDR = 0xA9001FFF
+ BUS_INTERFACE SOPB = opb_v20_0
+ PORT Sys_Intr1 = ps2_1_intr
+ PORT Sys_Intr2 = ps2_2_intr
+ PORT Clkin1 = ps2_clk_rx_1
+ PORT Clkin2 = ps2_clk_rx_2
+ PORT Clkpd1 = ps2_clk_tx_1
+ PORT Clkpd2 = ps2_clk_tx_2
+ PORT Rx1 = ps2_d_rx_1
+ PORT Rx2 = ps2_d_rx_2
+ PORT Txpd1 = ps2_d_tx_1
+ PORT Txpd2 = ps2_d_tx_2
+ END
+
+ It would result in the following device tree nodes:
+
+ opb_ps2_dual_ref_0@a9000000 {
+ ranges = <0 a9000000 2000>;
+ // If this device had extra parameters, then they would
+ // go here.
+ ps2@0 {
+ compatible = "xlnx,opb-ps2-dual-ref-1.00.a";
+ reg = <0 40>;
+ interrupt-parent = <&opb-intc>;
+ interrupts = <3 0>;
+ cell-index = <0>;
+ };
+ ps2@1000 {
+ compatible = "xlnx,opb-ps2-dual-ref-1.00.a";
+ reg = <1000 40>;
+ interrupt-parent = <&opb-intc>;
+ interrupts = <3 0>;
+ cell-index = <0>;
+ };
+ };
+
+ Also, the system.mhs file defines bus attachments from the processor
+ to the devices. The device tree structure should reflect the bus
+ attachments. Again an example; this system.mhs fragment:
+
+ BEGIN ppc405_virtex4
+ PARAMETER INSTANCE = ppc405_0
+ PARAMETER HW_VER = 1.01.a
+ BUS_INTERFACE DPLB = plb_v34_0
+ BUS_INTERFACE IPLB = plb_v34_0
+ END
+
+ BEGIN opb_intc
+ PARAMETER INSTANCE = opb_intc_0
+ PARAMETER HW_VER = 1.00.c
+ PARAMETER C_BASEADDR = 0xD1000FC0
+ PARAMETER C_HIGHADDR = 0xD1000FDF
+ BUS_INTERFACE SOPB = opb_v20_0
+ END
+
+ BEGIN opb_uart16550
+ PARAMETER INSTANCE = opb_uart16550_0
+ PARAMETER HW_VER = 1.00.d
+ PARAMETER C_BASEADDR = 0xa0000000
+ PARAMETER C_HIGHADDR = 0xa0001FFF
+ BUS_INTERFACE SOPB = opb_v20_0
+ END
+
+ BEGIN plb_v34
+ PARAMETER INSTANCE = plb_v34_0
+ PARAMETER HW_VER = 1.02.a
+ END
+
+ BEGIN plb_bram_if_cntlr
+ PARAMETER INSTANCE = plb_bram_if_cntlr_0
+ PARAMETER HW_VER = 1.00.b
+ PARAMETER C_BASEADDR = 0xFFFF0000
+ PARAMETER C_HIGHADDR = 0xFFFFFFFF
+ BUS_INTERFACE SPLB = plb_v34_0
+ END
+
+ BEGIN plb2opb_bridge
+ PARAMETER INSTANCE = plb2opb_bridge_0
+ PARAMETER HW_VER = 1.01.a
+ PARAMETER C_RNG0_BASEADDR = 0x20000000
+ PARAMETER C_RNG0_HIGHADDR = 0x3FFFFFFF
+ PARAMETER C_RNG1_BASEADDR = 0x60000000
+ PARAMETER C_RNG1_HIGHADDR = 0x7FFFFFFF
+ PARAMETER C_RNG2_BASEADDR = 0x80000000
+ PARAMETER C_RNG2_HIGHADDR = 0xBFFFFFFF
+ PARAMETER C_RNG3_BASEADDR = 0xC0000000
+ PARAMETER C_RNG3_HIGHADDR = 0xDFFFFFFF
+ BUS_INTERFACE SPLB = plb_v34_0
+ BUS_INTERFACE MOPB = opb_v20_0
+ END
+
+ Gives this device tree (some properties removed for clarity):
+
+ plb-v34-0 {
+ #address-cells = <1>;
+ #size-cells = <1>;
+ device_type = "ibm,plb";
+ ranges; // 1:1 translation
+
+ plb-bram-if-cntrl-0@ffff0000 {
+ reg = <ffff0000 10000>;
+ }
+
+ opb-v20-0 {
+ #address-cells = <1>;
+ #size-cells = <1>;
+ ranges = <20000000 20000000 20000000
+ 60000000 60000000 20000000
+ 80000000 80000000 40000000
+ c0000000 c0000000 20000000>;
+
+ opb-uart16550-0@a0000000 {
+ reg = <a00000000 2000>;
+ };
+
+ opb-intc-0@d1000fc0 {
+ reg = <d1000fc0 20>;
+ };
+ };
+ };
+
+ That covers the general approach to binding xilinx IP cores into the
+ device tree. The following are bindings for specific devices:
+
+ i) Xilinx ML300 Framebuffer
+
+ Simple framebuffer device from the ML300 reference design (also on the
+ ML403 reference design as well as others).
+
+ Optional properties:
+ - resolution = <xres yres> : pixel resolution of framebuffer. Some
+ implementations use a different resolution.
+ Default is <d#640 d#480>
+ - virt-resolution = <xvirt yvirt> : Size of framebuffer in memory.
+ Default is <d#1024 d#480>.
+ - rotate-display (empty) : rotate display 180 degrees.
+
+ ii) Xilinx SystemACE
+
+ The Xilinx SystemACE device is used to program FPGAs from an FPGA
+ bitstream stored on a CF card. It can also be used as a generic CF
+ interface device.
+
+ Optional properties:
+ - 8-bit (empty) : Set this property for SystemACE in 8 bit mode
+
+ iii) Xilinx EMAC and Xilinx TEMAC
+
+ Xilinx Ethernet devices. In addition to general xilinx properties
+ listed above, nodes for these devices should include a phy-handle
+ property, and may include other common network device properties
+ like local-mac-address.
+
+ iv) Xilinx Uartlite
+
+ Xilinx uartlite devices are simple fixed speed serial ports.
+
+ Requred properties:
+ - current-speed : Baud rate of uartlite
+
More devices will be defined as this spec matures.

* Fast timers for ETRAX100/ETRAX100LX
- * This may be useful in other OS than Linux so use 2 space indentation...
*
- * $Log: fasttimer.c,v $
- * Revision 1.9 2005/03/04 08:16:16 starvik
- * Merge of Linux 2.6.11.
- *
- * Revision 1.8 2005/01/05 06:09:29 starvik
- * cli()/sti() will be obsolete in 2.6.11.
- *
- * Revision 1.7 2005/01/03 13:35:46 starvik
- * Removed obsolete stuff.
- * Mark fast timer IRQ as not shared.
- *
- * Revision 1.6 2004/05/14 10:18:39 starvik
- * Export fast_timer_list
- *
- * Revision 1.5 2004/05/14 07:58:01 starvik
- * Merge of changes from 2.4
- *
- * Revision 1.4 2003/07/04 08:27:41 starvik
- * Merge of Linux 2.5.74
- *
- * Revision 1.3 2002/12/12 08:26:32 starvik
- * Don't use C-comments inside CVS comments
- *
- * Revision 1.2 2002/12/11 15:42:02 starvik
- * Extracted v10 (ETRAX 100LX) specific stuff from arch/cris/kernel/
- *
- * Revision 1.1 2002/11/18 07:58:06 starvik
- * Fast timers (from Linux 2.4)
- *
- * Revision 1.5 2002/10/15 06:21:39 starvik
- * Added call to init_waitqueue_head
- *
- * Revision 1.4 2002/05/28 17:47:59 johana
- * Added del_fast_timer()
- *
- * Revision 1.3 2002/05/28 16:16:07 johana
- * Handle empty fast_timer_list
- *
- * Revision 1.2 2002/05/27 15:38:42 johana
- * Made it compile without warnings on Linux 2.4.
- * (includes, wait_queue, PROC_FS and snprintf)
- *
- * Revision 1.1 2002/05/27 15:32:25 johana
- * arch/etrax100/kernel/fasttimer.c v1.8 from the elinux tree.
- *
- * Revision 1.8 2001/11/27 13:50:40 pkj
- * Disable interrupts while stopping the timer and while modifying the
- * list of active timers in timer1_handler() as it may be interrupted
- * by other interrupts (e.g., the serial interrupt) which may add fast
- * timers.
- *
- * Revision 1.7 2001/11/22 11:50:32 pkj
- * * Only store information about the last 16 timers.
- * * proc_fasttimer_read() now uses an allocated buffer, since it
- * requires more space than just a page even for only writing the
- * last 16 timers. The buffer is only allocated on request, so
- * unless /proc/fasttimer is read, it is never allocated.
- * * Renamed fast_timer_started to fast_timers_started to match
- * fast_timers_added and fast_timers_expired.
- * * Some clean-up.
- *
- * Revision 1.6 2000/12/13 14:02:08 johana
- * Removed volatile for fast_timer_list
- *
- * Revision 1.5 2000/12/13 13:55:35 johana
- * Added DEBUG_LOG, added som cli() and cleanup
- *
- * Revision 1.4 2000/12/05 13:48:50 johana
- * Added range check when writing proc file, modified timer int handling
- *
- * Revision 1.3 2000/11/23 10:10:20 johana
- * More debug/logging possibilities.
- * Moved GET_JIFFIES_USEC() to timex.h and time.c
- *
- * Revision 1.2 2000/11/01 13:41:04 johana
- * Clean up and bugfixes.
- * Created new do_gettimeofday_fast() that gets a timeval struct
- * with time based on jiffies and *R_TIMER0_DATA, uses a table
- * for fast conversion of timer value to microseconds.
- * (Much faster the standard do_gettimeofday() and we don't really
- * want to use the true time - we want the "uptime" so timers don't screw up
- * when we change the time.
- * TODO: Add efficient support for continuous timers as well.
- *
- * Revision 1.1 2000/10/26 15:49:16 johana
- * Added fasttimer, highresolution timers.

- allows bus write transfers to be combined into a larger transfer
- before bursting over the PCI/AGP bus. This can increase performance
- of image write operations 2.5 times or more. Saying Y here creates a

- as well.

- kexec is a system call that implements the ability to shutdown your

- but it is independent of the system firmware. And like a reboot
- you can start any kernel with it, not just Linux.
-
- The name comes from the similarity to the exec system call.
-
- It is an ongoing process to be certain the hardware in a machine
- is properly shutdown, so do not be surprised if this code does not
- initially work for you. It may help to enable device hotplugging
- support. As of this writing the exact hardware interface is
- strongly in flux, so no good recommendation can be made.

-config CRASH_DUMP

- help
- Generate crash dump after being started by kexec.
- This should be normally only set in special crash dump kernels
- which are loaded in the main kernel with kexec-tools into
- a specially reserved region and then later executed after
- a crash by kdump/kexec. The crash dump kernel must be compiled
- to a memory address not used by the main kernel or BIOS using
- PHYSICAL_START, or it must be built as a relocatable image
- (CONFIG_RELOCATABLE=y).
- For more details see Documentation/kdump/kdump.txt
-
-config RELOCATABLE
- bool "Build a relocatable kernel (EXPERIMENTAL)"
- depends on EXPERIMENTAL
- help
- Builds a relocatable kernel. This enables loading and running
- a kernel binary from a different physical address than it has
- been compiled for.
-
- One use is for the kexec on panic case where the recovery kernel
- must live at a different physical address than the primary
- kernel.
-
- Note: If CONFIG_RELOCATABLE=y, then the kernel runs from the address
- it has been loaded at and the compile time physical address
- (CONFIG_PHYSICAL_START) is ignored.
-
-config PHYSICAL_START
- hex "Physical address where the kernel is loaded" if (EMBEDDED || CRASH_DUMP)
- default "0x200000"
- help
- This gives the physical address where the kernel is loaded. It
- should be aligned to 2MB boundary.
-
- If kernel is a not relocatable (CONFIG_RELOCATABLE=n) then
- bzImage will decompress itself to above physical address and
- run from there. Otherwise, bzImage will run from the address where
- it has been loaded by the boot loader and will ignore above physical
- address.
-
- In normal kdump cases one does not have to set/change this option
- as now bzImage can be compiled as a completely relocatable image
- (CONFIG_RELOCATABLE=y) and be used to load and run from a different
- address. This option is mainly useful for the folks who don't want
- to use a bzImage for capturing the crash dump and want to use a
- vmlinux instead.
-
- So if you are using bzImage for capturing the crash dump, leave
- the value here unchanged to 0x200000 and set CONFIG_RELOCATABLE=y.
- Otherwise if you plan to use vmlinux for capturing the crash dump
- change this value to start of the reserved region (Typically 16MB
- 0x1000000). In other words, it can be set based on the "X" value as
- specified in the "crashkernel=YM@XM" command line boot parameter
- passed to the panic-ed kernel. Typically this parameter is set as
- crashkernel=64M@16M. Please take a look at
- Documentation/kdump/kdump.txt for more details about crash dumps.
-
- Usage of bzImage for capturing the crash dump is advantageous as
- one does not have to build two kernels. Same kernel can be used
- as production kernel and capture kernel.
-
- Don't change this unless you know what you are doing.

-config SECCOMP
- bool "Enable seccomp to safely compute untrusted bytecode"

- help
- This kernel feature is useful for number crunching applications
- that may need to compute untrusted bytecode during their
- execution. By using pipes or other transports made available to
- the process as file descriptors supporting the read/write
- syscalls, it's possible to isolate those applications in
- their own address space using seccomp. Once seccomp is
- enabled via /proc/<pid>/seccomp, it cannot be disabled
- and the task is only allowed to execute a few safe syscalls
- defined by each seccomp mode.

-config CC_STACKPROTECTOR
- bool "Enable -fstack-protector buffer overflow detection (EXPERIMENTAL)"

- help
- This option turns on the -fstack-protector GCC feature. This
- feature puts, at the beginning of critical functions, a canary
- value on the stack just before the return address, and validates
- the value just before actually returning. Stack based buffer
- overflows (that need to overwrite this return address) now also
- overwrite the canary, which gets detected and the attack is then
- neutralized via a kernel panic.
-
- This feature requires gcc version 4.2 or above, or a distribution
- gcc with the feature backported. Older versions are automatically
- detected and for those versions, this configuration option is ignored.
-
-config CC_STACKPROTECTOR_ALL
- bool "Use stack-protector for all functions"

+ bool "Use multiple sector mode for Programmed Input/Output by default"
+ help
+ This setting is irrelevant for most IDE disks, with direct memory
+ access, to which multiple sector mode does not apply. Multiple sector
+ mode is a feature of most modern IDE hard drives, permitting the
+ transfer of multiple sectors per Programmed Input/Output interrupt,
+ rather than the usual one sector per interrupt. When this feature is
+ enabled, it can reduce operating system overhead for disk Programmed
+ Input/Output. On some systems, it also can increase the data
+ throughput of Programmed Input/Output. Some drives, however, seemed
+ to run slower with multiple sector mode enabled. Some drives claimed
+ to support multiple sector mode, but lost data at some settings.
+ Under rare circumstances, such failures could result in massive
+ filesystem corruption.
+
+ If you get the following error, try to say Y here:
hda: set_multmode: status=0x51 { DriveReady SeekComplete Error }
hda: set_multmode: error=0x04 { DriveStatusError }
CD-ROM drive, you can say N to all other CD-ROM options, but be sure
to say Y or M to "ISO 9660 CD-ROM file system support".
- Note that older versions of LILO (LInux LOader) cannot properly deal
- with IDE/ATAPI CD-ROMs, so install LILO 16 or higher, available from

- *
- * Revision 1.48 2003/05/30 11:03:57 johana
- * Implemented rs_send_xchar() by disabling the DMA and writing manually.
- * Added e100_disable_txdma_channel() and e100_enable_txdma_channel().
- * Fixed rs_throttle() and rs_unthrottle() to properly call rs_send_xchar
- * instead of setting info->x_char and check the CRTSCTS flag before

- *
- * Revision 1.14 2003/04/09 08:12:44 pkj
- * Corrected typo changes made upstream.

- * Added arch/ to v10 specific includes
- * Added fix from Linux 2.4 in serial.c (flush_to_flip_buffer)
- *
- * Revision 1.7 2002/12/06 07:13:57 starvik
- * Corrected work queue stuff
- * Removed CONFIG_ETRAX_SERIAL_FLUSH_DMA_FAST
- *
- * Revision 1.6 2002/11/21 07:17:46 starvik
- * Change static inline to extern inline where otherwise outlined with gcc-3.2
- *
- * Revision 1.5 2002/11/14 15:59:49 starvik
- * Linux 2.5 port of the latest serial driver from 2.4. The work queue stuff
- * probably doesn't work yet.
- *
- * Revision 1.42 2002/11/05 09:08:47 johana
- * Better implementation of rs_stop() and rs_start() that uses the XOFF
- * register to start/stop transmission.
- * change_speed() also initilises XOFF register correctly so that
- * auto_xoff is enabled when IXON flag is set by user.
- * This gives fast XOFF response times.
- *
- * Revision 1.41 2002/11/04 18:40:57 johana
- * Implemented rs_stop() and rs_start().
- * Simple tests using hwtestserial indicates that this should be enough
- * to make it work.
- *
- * Revision 1.40 2002/10/14 05:33:18 starvik
- * RS-485 uses fast timers even if SERIAL_FAST_TIMER is disabled
- *
- * Revision 1.39 2002/09/30 21:00:57 johana
- * Support for CONFIG_ETRAX_SERx_DTR_RI_DSR_CD_MIXED where the status and
- * control pins can be mixed between PA and PB.
- * If no serial port uses MIXED old solution is used
- * (saves a few bytes and cycles).
- * control_pins struct uses masks instead of bit numbers.
- * Corrected dummy values and polarity in line_info() so
- * /proc/tty/driver/serial is now correct.
- * (the E100_xxx_GET() macros is really active low - perhaps not obvious)
- *
- * Revision 1.38 2002/08/23 11:01:36 starvik
- * Check that serial port is enabled in all interrupt handlers to avoid
- * restarts of DMA channels not assigned to serial ports
- *
- * Revision 1.37 2002/08/13 13:02:37 bjornw
- * Removed some warnings because of unused code
- *
- * Revision 1.36 2002/08/08 12:50:01 starvik
- * Serial interrupt is shared with synchronous serial port driver
- *
- * Revision 1.35 2002/06/03 10:40:49 starvik
- * Increased RS-485 RTS toggle timer to 2 characters
- *
- * Revision 1.34 2002/05/28 18:59:36 johana
- * Whitespace and comment fixing to be more like etrax100ser.c 1.71.
- *
- * Revision 1.33 2002/05/28 17:55:43 johana
- * RS-485 uses FAST_TIMER if enabled, and starts a short (one char time)
- * timer from tranismit_chars (interrupt context).
- * The timer toggles RTS in interrupt context when expired giving minimum
- * latencies.
- *
- * Revision 1.32 2002/05/22 13:58:00 johana
- * Renamed rs_write() to raw_write() and made it inline.
- * New rs_write() handles RS-485 if configured and enabled
- * (moved code from e100_write_rs485()).
- * RS-485 ioctl's uses copy_from_user() instead of verify_area().
- *
- * Revision 1.31 2002/04/22 11:20:03 johana
- * Updated copyright years.
- *
- * Revision 1.30 2002/04/22 09:39:12 johana
- * RS-485 support compiles.
- *
- * Revision 1.29 2002/01/14 16:10:01 pkj
- * Allocate the receive buffers dynamically. The static 4kB buffer was
- * too small for the peaks. This means that we can get rid of the extra
- * buffer and the copying to it. It also means we require less memory
- * under normal operations, but can use more when needed (there is a
- * cap at 64kB for safety reasons). If there is no memory available
- * we panic(), and die a horrible death...
- *
- * Revision 1.28 2001/12/18 15:04:53 johana
- * Cleaned up write_rs485() - now it works correctly without padding extra
- * char.
- * Added sane default initialisation of rs485.
- * Added #ifdef around dummy variables.
- *
- * Revision 1.27 2001/11/29 17:00:41 pkj
- * 2kB seems to be too small a buffer when using 921600 bps,
- * so increase it to 4kB (this was already done for the elinux
- * version of the serial driver).
- *
- * Revision 1.26 2001/11/19 14:20:41 pkj
- * Minor changes to comments and unused code.
- *
- * Revision 1.25 2001/11/12 20:03:43 pkj
- * Fixed compiler warnings.
- *
- * Revision 1.24 2001/11/12 15:10:05 pkj
- * Total redesign of the receiving part of the serial driver.
- * Uses eight chained descriptors to write to a 4kB buffer.
- * This data is then serialised into a 2kB buffer. From there it
- * is copied into the TTY's flip buffers when they become available.
- * A lot of copying, and the sizes of the buffers might need to be
- * tweaked, but all in all it should work better than the previous
- * version, without the need to modify the TTY code in any way.
- * Also note that erroneous bytes are now correctly marked in the
- * flag buffers (instead of always marking the first byte).
- *
- * Revision 1.23 2001/10/30 17:53:26 pkj
- * * Set info->uses_dma to 0 when a port is closed.
- * * Mark the timer1 interrupt as a fast one (SA_INTERRUPT).
- * * Call start_flush_timer() in start_receive() if
- * CONFIG_ETRAX_SERIAL_FLUSH_DMA_FAST is defined.
- *
- * Revision 1.22 2001/10/30 17:44:03 pkj
- * Use %lu for received and transmitted counters in line_info().
- *
- * Revision 1.21 2001/10/30 17:40:34 pkj
- * Clean-up. The only change to functionality is that
- * CONFIG_ETRAX_SERIAL_RX_TIMEOUT_TICKS(=5) is used instead of
- * MAX_FLUSH_TIME(=8).
- *
- * Revision 1.20 2001/10/30 15:24:49 johana
- * Added char_time stuff from 2.0 driver.
- *
- * Revision 1.19 2001/10/30 15:23:03 johana
- * Merged with 1.13.2 branch + fixed indentation
- * and changed CONFIG_ETRAX100_XYS to CONFIG_ETRAX_XYZ
- *
- * Revision 1.18 2001/09/24 09:27:22 pkj
- * Completed ext_baud_table[] in cflag_to_baud() and cflag_to_etrax_baud().
- *
- * Revision 1.17 2001/08/24 11:32:49 ronny
- * More fixes for the CONFIG_ETRAX_SERIAL_PORT0 define.
- *
- * Revision 1.16 2001/08/24 07:56:22 ronny
- * Added config ifdefs around ser0 irq requests.
- *
- * Revision 1.15 2001/08/16 09:10:31 bjarne
- * serial.c - corrected the initialization of rs_table, the wrong defines
- * where used.
- * Corrected a test in timed_flush_handler.
- * Changed configured to enabled.
- * serial.h - Changed configured to enabled.
- *
- * Revision 1.14 2001/08/15 07:31:23 bjarne
- * Introduced two new members to the e100_serial struct.
- * configured - Will be set to 1 if the port has been configured in .config
- * uses_dma - Should be set to 1 if the port uses DMA. Currently it is set
- * to 1
- * when a port is opened. This is used to limit the DMA interrupt
- * routines to only manipulate DMA channels actually used by the
- * serial driver.
- *
- * Revision 1.13.2.2 2001/10/17 13:57:13 starvik
- * Receiver was broken by the break fixes
- *
- * Revision 1.13.2.1 2001/07/20 13:57:39 ronny
- * Merge with new stuff from etrax100ser.c. Works but haven't checked stuff
- * like break handling.
- *
- * Revision 1.13 2001/05/09 12:40:31 johana
- * Use DMA_NBR and IRQ_NBR defines from dma.h and irq.h
- *
- * Revision 1.12 2001/04/19 12:23:07 bjornw
- * CONFIG_RS485 -> CONFIG_ETRAX_RS485
- *
- * Revision 1.11 2001/04/05 14:29:48 markusl
- * Updated according to review remarks i.e.
- * -Use correct types in port structure to avoid compiler warnings
- * -Try to use IO_* macros whenever possible
- * -Open should never return -EBUSY
- *
- * Revision 1.10 2001/03/05 13:14:07 bjornw
- * Another spelling fix
- *
- * Revision 1.9 2001/02/23 13:46:38 bjornw
- * Spellling check
- *
- * Revision 1.8 2001/01/23 14:56:35 markusl
- * Made use of ser1 optional
- * Needed by USB
- *
- * Revision 1.7 2001/01/19 16:14:48 perf
- * Added kernel options for serial ports 234.
- * Changed option names from CONFIG_ETRAX100_XYZ to CONFIG_ETRAX_XYZ.
- *
- * Revision 1.6 2000/11/22 16:36:09 bjornw
- * Please marketing by using the correct case when spelling Etrax.
- *
- * Revision 1.5 2000/11/21 16:43:37 bjornw
- * Fixed so it compiles under CONFIG_SVINTO_SIM
- *
- * Revision 1.4 2000/11/15 17:34:12 bjornw
- * Added a timeout timer for flushing input channels. The interrupt-based
- * fast flush system should be easy to merge with this later (works the same
- * way, only with an irq instead of a system timer_list)
- *
- * Revision 1.3 2000/11/13 17:19:57 bjornw
- * * Incredibly, this almost complete rewrite of serial.c worked (at least
- * for output) the first time.
- *
- * Items worth noticing:
- *
- * No Etrax100 port 1 workarounds (does only compile on 2.4 anyway now)
- * RS485 is not ported (why can't it be done in userspace as on x86 ?)
- * Statistics done through async_icount - if any more stats are needed,
- * that's the place to put them or in an arch-dep version of it.
- * timeout_interrupt and the other fast timeout stuff not ported yet
- * There be dragons in this 3k+ line driver
- *
- * Revision 1.2 2000/11/10 16:50:28 bjornw
- * First shot at a 2.4 port, does not compile totally yet
- *
- * Revision 1.1 2000/11/10 16:47:32 bjornw
- * Added verbatim copy of rev 1.49 etrax100ser.c from elinux
- *
- * Revision 1.49 2000/10/30 15:47:14 tobiasa
- * Changed version number.
- *
- * Revision 1.48 2000/10/25 11:02:43 johana
- * Changed %ul to %lu in printf's
- *
- * Revision 1.47 2000/10/18 15:06:53 pkj
- * Compile correctly with CONFIG_ETRAX_SERIAL_FLUSH_DMA_FAST and
- * CONFIG_ETRAX_SERIAL_PROC_ENTRY together.
- * Some clean-up of the /proc/serial file.
- *
- * Revision 1.46 2000/10/16 12:59:40 johana
- * Added CONFIG_ETRAX_SERIAL_PROC_ENTRY for statistics and debug info.
- *
- * Revision 1.45 2000/10/13 17:10:59 pkj
- * Do not flush DMAs while flipping TTY buffers.
- *
- * Revision 1.44 2000/10/13 16:34:29 pkj
- * Added a delay in ser_interrupt() for 2.3ms when an error is detected.
- * We do not know why this delay is required yet, but without it the
- * irmaflash program does not work (this was the program that needed
- * the ser_interrupt() to be needed in the first place). This should not
- * affect normal use of the serial ports.
- *
- * Revision 1.43 2000/10/13 16:30:44 pkj
- * New version of the fast flush of serial buffers code. This time
- * it is localized to the serial driver and uses a fast timer to
- * do the work.
- *
- * Revision 1.42 2000/10/13 14:54:26 bennyo
- * Fix for switching RTS when using rs485
- *
- * Revision 1.41 2000/10/12 11:43:44 pkj
- * Cleaned up a number of comments.
- *
- * Revision 1.40 2000/10/10 11:58:39 johana
- * Made RS485 support generic for all ports.
- * Toggle rts in interrupt if no delay wanted.
- * WARNING: No true transmitter empty check??
- * Set d_wait bit when sending data so interrupt is delayed until
- * fifo flushed. (Fix tcdrain() problem)
- *
- * Revision 1.39 2000/10/04 16:08:02 bjornw
- * * Use virt_to_phys etc. for DMA addresses
- * * Removed CONFIG_FLUSH_DMA_FAST hacks
- * * Indentation fix
- *
- * Revision 1.38 2000/10/02 12:27:10 mattias
- * * added variable used when using fast flush on serial dma.
- * (CONFIG_FLUSH_DMA_FAST)
- *
- * Revision 1.37 2000/09/27 09:44:24 pkj
- * Uncomment definition of SERIAL_HANDLE_EARLY_ERRORS.
- *
- * Revision 1.36 2000/09/20 13:12:52 johana
- * Support for CONFIG_ETRAX_SERIAL_RX_TIMEOUT_TICKS:
- * Number of timer ticks between flush of receive fifo (1 tick = 10ms).
- * Try 0-3 for low latency applications. Approx 5 for high load
- * applications (e.g. PPP). Maybe this should be more adaptive some day...
- *
- * Revision 1.35 2000/09/20 10:36:08 johana
- * Typo in get_lsr_info()
- *
- * Revision 1.34 2000/09/20 10:29:59 johana
- * Let rs_chars_in_buffer() check fifo content as well.
- * get_lsr_info() might work now (not tested).
- * Easier to change the port to debug.
- *
- * Revision 1.33 2000/09/13 07:52:11 torbjore
- * Support RS485
- *
- * Revision 1.32 2000/08/31 14:45:37 bjornw
- * After sending a break we need to reset the transmit DMA channel
- *
- * Revision 1.31 2000/06/21 12:13:29 johana
- * Fixed wait for all chars sent when closing port.
- * (Used to always take 1 second!)
- * Added shadows for directions of status/ctrl signals.
- *
- * Revision 1.30 2000/05/29 16:27:55 bjornw
- * Simulator ifdef moved a bit
- *
- * Revision 1.29 2000/05/09 09:40:30 mattias
- * * Added description of dma registers used in timeout_interrupt
- * * Removed old code
- *
- * Revision 1.28 2000/05/08 16:38:58 mattias
- * * Bugfix for flushing fifo in timeout_interrupt
- * Problem occurs when bluetooth stack waits for a small number of bytes
- * containing an event acknowledging free buffers in bluetooth HW
- * As before, data was stuck in fifo until more data came on uart and
- * flushed it up to the stack.
- *
- * Revision 1.27 2000/05/02 09:52:28 jonasd
- * Added fix for peculiar etrax behaviour when eop is forced on an empty
- * fifo. This is used when flashing the IRMA chip. Disabled by default.
- *
- * Revision 1.26 2000/03/29 15:32:02 bjornw
- * 2.0.34 updates
- *
- * Revision 1.25 2000/02/16 16:59:36 bjornw
- * * Receive DMA directly into the flip-buffer, eliminating an intermediary
- * receive buffer and a memcpy. Will avoid some overruns.
- * * Error message on debug port if an overrun or flip buffer overrun occurs.
- * * Just use the first byte in the flag flip buffer for errors.
- * * Check for timeout on the serial ports only each 5/100 s, not 1/100.
- *
- * Revision 1.24 2000/02/09 18:02:28 bjornw
- * * Clear serial errors (overrun, framing, parity) correctly. Before, the
- * receiver would get stuck if an error occurred and we did not restart
- * the input DMA.
- * * Cosmetics (indentation, some code made into inlines)
- * * Some more debug options
- * * Actually shut down the serial port (DMA irq, DMA reset, receiver stop)
- * when the last open is closed. Corresponding fixes in startup().
- * * rs_close() "tx FIFO wait" code moved into right place, bug & -> && fixed
- * and make a special case out of port 1 (R_DMA_CHx_STATUS is broken for that)
- * * e100_disable_rx/enable_rx just disables/enables the receiver, not RTS
- *
- * Revision 1.23 2000/01/24 17:46:19 johana
- * Wait for flush of DMA/FIFO when closing port.
- *
- * Revision 1.22 2000/01/20 18:10:23 johana
- * Added TIOCMGET ioctl to return modem status.
- * Implemented modem status/control that works with the extra signals
- * (DTR, DSR, RI,CD) as well.
- * 3 different modes supported:
- * ser0 on PB (Bundy), ser1 on PB (Lisa) and ser2 on PA (Bundy)
- * Fixed DEF_TX value that caused the serial transmitter pin (txd) to go to 0 when
- * closing the last filehandle, NASTY!.
- * Added break generation, not tested though!
- * Use IRQF_SHARED when request_irq() for ser2 and ser3 (shared with) par0 and par1.
- * You can't use them at the same time (yet..), but you can hopefully switch
- * between ser2/par0, ser3/par1 with the same kernel config.
- * Replaced some magic constants with defines
- *

+requires packet signing but client has disabled it. When mounted
+with cifsacl mount option - mode bits are approximated based
