- * Linux Ethernet device driver for the 3Com Etherlink Plus (3C505)
- * By Craig Southeren, Juha Laiho and Philip Blundell
- *
- * 3c505.c This module implements an interface to the 3Com
- * Etherlink Plus (3c505) Ethernet card. Linux device
- * driver interface reverse engineered from the Linux 3C509
- * device drivers. Some 3C505 information gleaned from
- * the Crynwr packet driver. Still this driver would not
- * be here without 3C505 technical reference provided by
- * 3Com.

-/* Theory of operation:
- *
- * The 3c505 is quite an intelligent board. All communication with it is done
- * by means of Primary Command Blocks (PCBs); these are transferred using PIO
- * through the command register. The card has 256k of on-board RAM, which is
- * used to buffer received packets. It might seem at first that more buffers
- * are better, but in fact this isn't true. From my tests, it seems that
- * more than about 10 buffers are unnecessary, and there is a noticeable
- * performance hit in having more active on the card. So the majority of the
- * card's memory isn't, in fact, used. Sadly, the card only has one transmit
- * buffer and, short of loading our own firmware into it (which is what some
- * drivers resort to) there's nothing we can do about this.
- *
- * We keep up to 4 "receive packet" commands active on the board at a time.
- * When a packet comes in, so long as there is a receive command active, the
- * board will send us a "packet received" PCB and then add the data for that
- * packet to the DMA queue. If a DMA transfer is not already in progress, we
- * set one up to start uploading the data. We have to maintain a list of
- * backlogged receive packets, because the card may decide to tell us about
- * a newly-arrived packet at any time, and we may not be able to start a DMA
- * transfer immediately (ie one may already be going on). We can't NAK the
- * PCB, because then it would throw the packet away.
- *
- * Trying to send a PCB to the card at the wrong moment seems to have bad
- * effects. If we send it a transmit PCB while a receive DMA is happening,
- * it will just NAK the PCB and so we will have wasted our time. Worse, it
- * sometimes seems to interrupt the transfer. The majority of the low-level
- * code is protected by one huge semaphore -- "busy" -- which is set whenever
- * it probably isn't safe to do anything to the card. The receive routine
- * must gain a lock on "busy" before it can start a DMA transfer, and the
- * transmit routine must gain a lock before it sends the first PCB to the card.
- * The send_pcb() routine also has an internal semaphore to protect it against
- * being re-entered (which would be disastrous) -- this is needed because
- * several things can happen asynchronously (re-priming the receiver and
- * asking the card for statistics, for example). send_pcb() will also refuse
- * to talk to the card at all if a DMA upload is happening. The higher-level
- * networking code will reschedule a later retry if some part of the driver
- * is blocked. In practice, this doesn't seem to happen very often.
- */
-
-/* This driver may now work with revision 2.x hardware, since all the read
- * operations on the HCR have been removed (we now keep our own softcopy).
- * But I don't have an old card to test it on.
- *
- * This has had the bad effect that the autoprobe routine is now a bit
- * less friendly to other devices. However, it was never very good.
- * before, so I doubt it will hurt anybody.
- */
-
-/* The driver is a mess. I took Craig's and Juha's code, and hacked it firstly
- * to make it more reliable, and secondly to add DMA mode. Many things could
- * probably be done better; the concurrency protection is particularly awful.

- The host can map 16K, 32K, 48K, or 64K of the 64K memory into
- 0x0[CD][08]0000, or all 64K into 0xF[02468]0000.

- We can account for this be setting the 'SBC Base' entry in the ISCP table

- What follows in 'init_words[]' is the "program" that is downloaded to the

- reset address 0xfffff6. This is designed to be similar to the EtherExpress,
- thus the unusual location of the SCB at 0x0008.
-
- Even with the additional "don't care" values, doing it this way takes less
- program space than initializing the individual tables, and I feel it's much
- cleaner.
-
- The databook is particularly useless for the first two structures, I had
- to use the Crynwr driver as an example.

- That's it: only 86 bytes to set up the beast, including every extra
- command available. The 170 byte buffer at DUMP_DATA is shared between the
- Dump command (called only by the diagnostic program) and the SetMulticastList
- command.
-
- To complete the memory setup you only have to write the station address at
- SA_OFFSET and create the Tx & Rx buffer lists.
-
- The Tx command chain and buffer list is setup as follows:
- A Tx command table, with the data buffer pointing to...
- A Tx data buffer descriptor. The packet is in a single buffer, rather than
- chaining together several smaller buffers.
- A NoOp command, which initially points to itself,
- And the packet data.
-
- A transmit is done by filling in the Tx command table and data buffer,
- re-writing the NoOp command, and finally changing the offset of the last
- command to point to the current Tx command. When the Tx command is finished,
- it jumps to the NoOp, when it loops until the next Tx command changes the
- "link offset" in the NoOp. This way the 82586 never has to go through the
- slow restart sequence.
-
- The Rx buffer list is set up in the obvious ring structure. We have enough
- memory (and low enough interrupt latency) that we can avoid the complicated
- Rx buffer linked lists by alway associating a full-size Rx data buffer with
- each Rx data frame.
-
- I current use four transmit buffers starting at TX_BUF_START (0x0100), and
- use the rest of memory, from RX_BUF_START to RX_BUF_END, for Rx buffers.

-
- Things remaining to do:
- Better record keeping of errors.
- Eliminate transmit interrupt to reduce overhead.
- Implement "concurrent processing". I won't be doing it!
-
- Bugs:
-
- If you have a problem of not detecting the 82595 during a
- reboot (warm reset), disable the FLASH memory should fix it.
- This is a compatibility hardware problem.
-
- Versions:
- 0.13b basic ethtool support (aris, 09/13/2004)
- 0.13a in memory shortage, drop packets also in board
- (Michael Westermann <mw@microdata-pos.de>, 07/30/2002)
- 0.13 irq sharing, rewrote probe function, fixed a nasty bug in
- hardware_send_packet and a major cleanup (aris, 11/08/2001)
- 0.12d fixing a problem with single card detected as eight eth devices
- fixing a problem with sudden drop in card performance
- (chris (asdn@go2.pl), 10/29/2001)
- 0.12c fixing some problems with old cards (aris, 01/08/2001)
- 0.12b misc fixes (aris, 06/26/2000)
- 0.12a port of version 0.12a of 2.2.x kernels to 2.3.x
- (aris (aris@conectiva.com.br), 05/19/2000)
- 0.11e some tweaks about multiple cards support (PdP, jul/aug 1999)
- 0.11d added __initdata, __init stuff; call spin_lock_init
- in eepro_probe1. Replaced "eepro" by dev->name. Augmented
- the code protected by spin_lock in interrupt routine
- (PdP, 12/12/1998)
- 0.11c minor cleanup (PdP, RMC, 09/12/1998)
- 0.11b Pascal Dupuis (dupuis@lei.ucl.ac.be): works as a module
- under 2.1.xx. Debug messages are flagged as KERN_DEBUG to
- avoid console flooding. Added locking at critical parts. Now
- the dawn thing is SMP safe.
- 0.11a Attempt to get 2.1.xx support up (RMC)
- 0.11 Brian Candler added support for multiple cards. Tested as
- a module, no idea if it works when compiled into kernel.
-
- 0.10e Rick Bressler notified me that ifconfig up;ifconfig down fails
- because the irq is lost somewhere. Fixed that by moving
- request_irq and free_irq to eepro_open and eepro_close respectively.
- 0.10d Ugh! Now Wakeup works. Was seriously broken in my first attempt.
- I'll need to find a way to specify an ioport other than
- the default one in the PnP case. PnP definitively sucks.
- And, yes, this is not the only reason.
- 0.10c PnP Wakeup Test for 595FX. uncomment #define PnPWakeup;
- to use.
- 0.10b Should work now with (some) Pro/10+. At least for
- me (and my two cards) it does. _No_ guarantee for
- function with non-Pro/10+ cards! (don't have any)
- (RMC, 9/11/96)
-
- 0.10 Added support for the Etherexpress Pro/10+. The
- IRQ map was changed significantly from the old
- pro/10. The new interrupt map was provided by
- Rainer M. Canavan (Canavan@Zeus.cs.bonn.edu).
- (BCH, 9/3/96)
-
- 0.09 Fixed a race condition in the transmit algorithm,
- which causes crashes under heavy load with fast
- pentium computers. The performance should also
- improve a bit. The size of RX buffer, and hence
- TX buffer, can also be changed via lilo or insmod.
- (BCH, 7/31/96)
-
- 0.08 Implement 32-bit I/O for the 82595TX and 82595FX
- based lan cards. Disable full-duplex mode if TPE
- is not used. (BCH, 4/8/96)
-
- 0.07a Fix a stat report which counts every packet as a
- heart-beat failure. (BCH, 6/3/95)
-
- 0.07 Modified to support all other 82595-based lan cards.
- The IRQ vector of the EtherExpress Pro will be set
- according to the value saved in the EEPROM. For other
- cards, I will do autoirq_request() to grab the next
- available interrupt vector. (BCH, 3/17/95)
-
- 0.06a,b Interim released. Minor changes in the comments and
- print out format. (BCH, 3/9/95 and 3/14/95)
-
- 0.06 First stable release that I am comfortable with. (BCH,
- 3/2/95)
-
- 0.05 Complete testing of multicast. (BCH, 2/23/95)
-
- 0.04 Adding multicast support. (BCH, 2/14/95)
-
- 0.03 First widely alpha release for public testing.
- (BCH, 2/14/95)

- Sources:
-
- This driver wouldn't have been written without the availability
- of the Crynwr's Lan595 driver source code. It helps me to
- familiarize with the 82595 chipset while waiting for the Intel

-
- This driver is written by cutting and pasting the skeleton.c driver
- provided by Donald Becker. I also borrowed the EEPROM routine from
- Donald Becker's 82586 driver.
-
- Datasheet for the Intel 82595 (including the TX and FX version). It

- The User Manual for the 82595. It provides a lot of the missing

- Details of the i82595.
-
-You will need either the datasheet or the user manual to understand what
-is going on here. The 82595 is very different from the 82586, 82593.
-
-The receive algorithm in eepro_rx() is just an implementation of the
-RCV ring structure that the Intel 82595 imposes at the hardware level.
-The receive buffer is set at 24K, and the transmit buffer is 8K. I
-am assuming that the total buffer memory is 32K, which is true for the
-Intel EtherExpress Pro/10. If it is less than that on a generic card,
-the driver will be broken.
-
-The transmit algorithm in the hardware_send_packet() is similar to the
-one in the eepro_rx(). The transmit buffer is a ring linked list.
-I just queue the next available packet to the end of the list. In my
-system, the 82595 is so fast that the list seems to always contain a
-single packet. In other systems with faster computers and more congested
-network traffics, the ring linked list should improve performance by
-allowing up to 8K worth of packets to be queued.
-
-The sizes of the receive and transmit buffers can now be changed via lilo
-or insmod. Lilo uses the appended line "ether=io,irq,debug,rx-buffer,eth0"
-where rx-buffer is in KB unit. Modules uses the parameter mem which is
-also in KB unit, for example "insmod io=io-address irq=0 mem=rx-buffer."
-The receive buffer has to be more than 3K or less than 29K. Otherwise,
-it is reset to the default of 24K, and, hence, 8K for the trasnmit
-buffer (transmit-buffer = 32K - receive-buffer).

-/* Intel EtherExpress 16 device driver for Linux
- *
- * Written by John Sullivan, 1995
- * based on original code by Donald Becker, with changes by
- * Alan Cox and Pauline Middelink.
- *
- * Support for 8-bit mode by Zoltan Szilagyi <zoltans@cs.arizona.edu>
- *
- * Many modifications, and currently maintained, by
- * Philip Blundell <philb@gnu.org>
- * Added the Compaq LTE Alan Cox <alan@lxorguk.ukuu.org.uk>
- * Added MCA support Adam Fritzler (now deleted)
- *
- * Note - this driver is experimental still - it has problems on faster
- * machines. Someone needs to sit down and go through it line by line with
- * a databook...
- */
-
-/* The EtherExpress 16 is a fairly simple card, based on a shared-memory
- * design using the i82586 Ethernet coprocessor. It bears no relationship,
- * as far as I know, to the similarly-named "EtherExpress Pro" range.
- *
- * Historically, Linux support for these cards has been very bad. However,
- * things seem to be getting better slowly.
- */
-
-/* If your card is confused about what sort of interface it has (eg it
- * persistently reports "10baseT" when none is fitted), running 'SOFTSET /BART'
- * or 'SOFTSET /LISA' from DOS seems to help.
- */
-
-/* Here's the scoop on memory mapping.
- *
- * There are three ways to access EtherExpress card memory: either using the
- * shared-memory mapping, or using PIO through the dataport, or using PIO
- * through the "shadow memory" ports.
- *
- * The shadow memory system works by having the card map some of its memory
- * as follows:
- *
- * (the low five bits of the SMPTR are ignored)
- *
- * base+0x4000..400f memory at SMPTR+0..15
- * base+0x8000..800f memory at SMPTR+16..31
- * base+0xc000..c007 dubious stuff (memory at SMPTR+16..23 apparently)
- * base+0xc008..c00f memory at 0x0008..0x000f
- *
- * This last set (the one at c008) is particularly handy because the SCB
- * lives at 0x0008. So that set of ports gives us easy random access to data
- * in the SCB without having to mess around setting up pointers and the like.
- * We always use this method to access the SCB (via the scb_xx() functions).
- *
- * Dataport access works by aiming the appropriate (read or write) pointer
- * at the first address you're interested in, and then reading or writing from
- * the dataport. The pointers auto-increment after each transfer. We use
- * this for data transfer.
- *
- * We don't use the shared-memory system because it allegedly doesn't work on
- * all cards, and because it's a bit more prone to go wrong (it's one more
- * thing to configure...).
- */
-
-/* Known bugs:
- *
- * - The card seems to want to give us two interrupts every time something
- * happens, where just one would be better.
- */
-
-/*
- *
- * Note by Zoltan Szilagyi 10-12-96:
- *
- * I've succeeded in eliminating the "CU wedged" messages, and hence the
- * lockups, which were only occurring with cards running in 8-bit mode ("force
- * 8-bit operation" in Intel's SoftSet utility). This version of the driver
- * sets the 82586 and the ASIC to 8-bit mode at startup; it also stops the
- * CU before submitting a packet for transmission, and then restarts it as soon
- * as the process of handing the packet is complete. This is definitely an
- * unnecessary slowdown if the card is running in 16-bit mode; therefore one
- * should detect 16-bit vs 8-bit mode from the EEPROM settings and act
- * accordingly. In 8-bit mode with this bugfix I'm getting about 150 K/s for
- * ftp's, which is significantly better than I get in DOS, so the overhead of
- * stopping and restarting the CU with each transmit is not prohibitive in
- * practice.
- *
- * Update by David Woodhouse 11/5/99:
- *
- * I've seen "CU wedged" messages in 16-bit mode, on the Alpha architecture.
- * I assume that this is because 16-bit accesses are actually handled as two
- * 8-bit accesses.

-A complete description of the 82596 is available from intel. Search for
-a file called "29021806.pdf". It is a complete description of the chip itself.
-To use it for the pws some additions are needed regarding generation of
-the PORT and CA signal, and the interrupt glue needed for a pc.
-I/O map:
-PORT SIZE ACTION MEANING
-0xCB0 2 WRITE Lower 16 bits for PORT command
-0xCB2 2 WRITE Upper 16 bits for PORT command, and issue of PORT command
-0xCB4 1 WRITE Generation of CA signal
-0xCB8 1 WRITE Clear interrupt glue

- * CAN YOU PLEASE REPORT ME YOUR PERFORMANCE EXPERIENCES !!.
- *
- * If you find a bug, please report me:
- * The kernel panic output and any kmsg from the ni52 driver
- * the ni5210-driver-version and the linux-kernel version
- * how many shared memory (memsize) on the netcard,
- * bootprom: yes/no, base_addr, mem_start
- * maybe the ni5210-card revision and the i82586 version
- *
- * autoprobe for: base_addr: 0x300,0x280,0x360,0x320,0x340
- * mem_start: 0xd0000,0xd2000,0xc8000,0xca000,0xd4000,0xd6000,
- * 0xd8000,0xcc000,0xce000,0xda000,0xdc000
- *
- * sources:
- * skeleton.c from Donald Becker
- *
- * I have also done a look in the following sources: (mail me if you need them)
- * crynwr-packet-driver by Russ Nelson
- * Garret A. Wollman's (fourth) i82586-driver for BSD
- * (before getting an i82596 (yes 596 not 586) manual, the existing drivers
- * helped me a lot to understand this tricky chip.)
- *
- * Known Problems:
- * The internal sysbus seems to be slow. So we often lose packets because of
- * overruns while receiving from a fast remote host.
- * This can slow down TCP connections. Maybe the newer ni5210 cards are
- * better. My experience is, that if a machine sends with more than about
- * 500-600K/s the fifo/sysbus overflows.
- *
- * IMPORTANT NOTE:
- * On fast networks, it's a (very) good idea to have 16K shared memory. With
- * 8K, we can store only 4 receive frames, so it can (easily) happen that a
- * remote machine 'overruns' our system.
- *
- * Known i82586/card problems (I'm sure, there are many more!):
- * Running the NOP-mode, the i82586 sometimes seems to forget to report
- * every xmit-interrupt until we restart the CU.
- * Another MAJOR bug is, that the RU sometimes seems to ignore the EL-Bit
- * in the RBD-Struct which indicates an end of the RBD queue.
- * Instead, the RU fetches another (randomly selected and
- * usually used) RBD and begins to fill it. (Maybe, this happens only if
- * the last buffer from the previous RFD fits exact into the queue and
- * the next RFD can't fetch an initial RBD. Anyone knows more? )
- *
- * results from ftp performance tests with Linux 1.2.5
- * send and receive about 350-400 KByte/s (peak up to 460 kbytes/s)
- * sending in NOP-mode: peak performance up to 530K/s (but better don't
- * run this mode)

-/* znet.c: An Zenith Z-Note ethernet driver for linux. */
-
-/*
- Written by Donald Becker.
-
- The author may be reached as becker@scyld.com.
- This driver is based on the Linux skeleton driver. The copyright of the
- skeleton driver is held by the United States Government, as represented
- by DIRNSA, and it is released under the GPL.
-
- Thanks to Mike Hollick for alpha testing and suggestions.
-
- References:
- The Crynwr packet driver.
-
- "82593 CSMA/CD Core LAN Controller" Intel datasheet, 1992
- Intel Microcommunications Databook, Vol. 1, 1990.
- As usual with Intel, the documentation is incomplete and inaccurate.
- I had to read the Crynwr packet driver to figure out how to actually
- use the i82593, and guess at what register bits matched the loosely
- related i82586.
-
- Theory of Operation
-
- The i82593 used in the Zenith Z-Note series operates using two(!) slave
- DMA channels, one interrupt, and one 8-bit I/O port.
-
- While there several ways to configure '593 DMA system, I chose the one
- that seemed commensurate with the highest system performance in the face
- of moderate interrupt latency: Both DMA channels are configured as
- recirculating ring buffers, with one channel (#0) dedicated to Rx and
- the other channel (#1) to Tx and configuration. (Note that this is
- different than the Crynwr driver, where the Tx DMA channel is initialized
- before each operation. That approach simplifies operation and Tx error
- recovery, but requires additional I/O in normal operation and precludes
- transmit buffer chaining.)
-
- Both rings are set to 8192 bytes using {TX,RX}_RING_SIZE. This provides
- a reasonable ring size for Rx, while simplifying DMA buffer allocation --
- DMA buffers must not cross a 128K boundary. (In truth the size selection
- was influenced by my lack of '593 documentation. I thus was constrained
- to use the Crynwr '593 initialization table, which sets the Rx ring size
- to 8K.)
-
- Despite my usual low opinion about Intel-designed parts, I must admit
- that the bulk data handling of the i82593 is a good design for
- an integrated system, like a laptop, where using two slave DMA channels
- doesn't pose a problem. I still take issue with using only a single I/O
- port. In the same controlled environment there are essentially no
- limitations on I/O space, and using multiple locations would eliminate
- the need for multiple operations when looking at status registers,
- setting the Rx ring boundary, or switching to promiscuous mode.
-
- I also question Zenith's selection of the '593: one of the advertised
- advantages of earlier Intel parts was that if you figured out the magic
- initialization incantation you could use the same part on many different
- network types. Zenith's use of the "FriendlyNet" (sic) connector rather
- than an on-board transceiver leads me to believe that they were planning
- to take advantage of this. But, uhmmm, the '593 omits all but ethernet
- functionality from the serial subsystem.

-/* 10/2002
-
- o Resurected for Linux 2.5+ by Marc Zyngier <maz@wild-wind.fr.eu.org> :
-
- - Removed strange DMA snooping in znet_sent_packet, which lead to
- TX buffer corruption on my laptop.
- - Use init_etherdev stuff.
- - Use kmalloc-ed DMA buffers.
- - Use as few global variables as possible.
- - Use proper resources management.
- - Use wireless/i82593.h as much as possible (structure, constants)
- - Compiles as module or build-in.
- - Now survives unplugging/replugging cable.
-
- Some code was taken from wavelan_cs.
-
- Tested on a vintage Zenith Z-Note 433Lnp+. Probably broken on
- anything else. Testers (and detailed bug reports) are welcome :-).
-
- o TODO :
-
- - Properly handle multicast
- - Understand why some traffic patterns add a 1s latency...
