-I OVERVIEW
-
- The 3c90X series ethernet cards are a group of high-performance busmaster
- DMA cards from 3Com. This particular driver supports both the 3c90x and
- the 3c90xB revision cards. 3C90xC family support has been tested to some
- degree but not extensively.
-
- Here's the licensing information:
-

- A PARTICULAR PURPOSE or MERCHANTABILITY. Please read the associated
- documentation "3c90x.txt" before compiling and using this driver.
-
-
-II FLASH PROMS
-
- The 3c90xB cards, according to the 3Com documentation, only accept the
- following flash memory chips:
-
- Atmel AT29C512 (64 kilobyte)
- Atmel AT29C010 (128 kilobyte)
-
- The 3c90x cards, according to the 3Com documentation, accept the
- following flash memory chips capacities:
-
- 64 kb (8 kB)
- 128 kb (16 kB)
- 256 kb (32 kB) and
- 512 kb (64 kB)
-
- Atmel AT29C512 (64 kilobyte) chips are specifically listed for both
- adapters, but flashing on the 3c905b cards would only be supported
- through the Atmel parts. Any device, of the supported size, should
- be supported when programmed by a dedicated PROM programmer (e.g.
- not the card).
-
- To use this driver in such a PROM, visit Atmel's web site and download
- their .PDF file containing a list of their distributors. Contact the
- distributors for pricing information. The prices are quite reasonable
- (about $3 US each for the 64 kB part), and are comparable to what one would
- expect for similarly sized standard EPROMs. And, the flash chips are much
- easier to work with, as they don't need to be UV-erased to be reprogrammed.
- The 3C905B card actually provides a method to program the flash memory
- while it is resident on board the card itself; if someone would like to
- write a small DOS program to do the programming, I can provide the
- information about the registers and so forth.
-
- A utility program, 3c90xutil, is provided with Etherboot in the 'contrib'
- directory that allows for the on-board flashing of the ROM while Linux
- is running. The program has been successfully used under Linux, but I
- have heard problem reports of its use under FreeBSD. Anyone willing to
- make it work under FreeBSD is more than welcome to do so!
-
- You also have the option of using EPROM chips - the 3C905B-TX-NM has been
- successfully tested with 27C256 (32kB) and 27C512 (64kB) chips with a
- specified access time of 100ns and faster.
-
-
-III GENERAL USE
-
- Normally, the basic procedure for using this driver is as follows:
-
- 1. Run the 3c90xcfg program on the driver diskette to enable the
- boot PROM and set it to 64k or 128k, as appropriate.
- 2. Build the appropriate 3c90x.fd0 or 3c90x.fd0 floppy image with
- possibly the value CFG_3C90X_XCVR defined to the transceiver type that
- you want to use (i.e., 10/100 rj45, AUI, coax, MII).
- 3. Run the floppy image on the PC to be network booted, to get
- it configured, and to verify that it will boot properly.
- 4. Build the 3c90x.rom or 3c90x.lzrom PROM image and program
- it into the flash or EPROM memory chip.
- 5. Put the PROM in the ethernet card, boot and enable 'boot from
- network first' in the system BIOS, save and reboot.
-
- Here are some issues to be aware of:
-
- 1. If you experience crashes or different behaviour when using the
- boot PROM, add the setting CFG_3C90X_BOOTROM_FIX and go through the
- steps 2-5 above. This works around a bug in some 3c905B cards (see
- below), but has some side-effects which may not be desirable.
- Please note that you have to boot off a floppy (not PROM!) once for
- this fix to take effect.
- 2. The possible need to manually set the CFG_3C90X_XCVR value to
- configure the transceiver type. Values are listed below.
- 3. The possible need to define CFG_3C90X_PRESERVE_XCVR for use in
- operating systems that don't intelligently determine the
- transceiver type.
-
- Some things that are on the 'To-Do' list, perhaps for me, but perhaps
- for any other volunteers out there:
-
- 1. Extend the driver to fully implement the auto-select
- algorithm if the card has multiple media ports.
- 2. Fix any bugs in the code <grin>....
- 3. Extend the driver to support the 3c905c revision cards
- "officially". Right now, the support has been primarily empirical
- and not based on 3c905C documentation.
-
- Now for the details....
-
- This driver has been tested on roughly 300 systems. The main two
- configuration issues to contend with are:
-
- 1. Ensure that PCI Busmastering is enabled for the adapter (configured
- in the CMOS setup)
- 2. Some systems don't work properly with the adapter when plug and
- play OS is enabled; I always set it to "No" or "Disabled" -- this makes
- it easier and really doesn't adversely affect anything.
-
- Roughly 95% of the systems worked when configured properly. A few
- have issues with booting locally once the boot PROM has been installed
- (this number has been less than 2%). Other configuration issues that
- to check:
-
- 1. Newer BIOS's actually work correctly with the network boot order.
- Set the network adapter first. Most older BIOS's automatically go to
- the network boot PROM first.
- 2. For systems where the adapter was already installed and is just
- having the PROM installed, try setting the "reset configuration data"
- to yes in the CMOS setup if the BIOS isn't seen at first. If your BIOS
- doesn't have this option, remove the card, start the system, shut down,
- install the card and restart (or switch to a different PCI slot).
- 3. Make sure the CMOS security settings aren't preventing a boot.
-
- The 3c905B cards have a significant 'bug' that relates to the flash prom:
- unless the card is set internally to the MII transceiver, it will only
- read the first 8k of the PROM image. Don't ask why -- it seems really
- obscure, but it has to do with the way they mux'd the address lines
- from the PCI bus to the ROM. Unfortunately, most of us are not using
- MII transceivers, and even the .lzrom image ends up being just a little
- bit larger than 8k. Note that the workaround for this is disabled by
- default, because the Windows NT 4.0 driver does not like it (no packets
- are transmitted).
-
- So, the solution that I've used is to internally set the card's nvram
- configuration to use MII when it boots. The 3c905b driver does this
- automatically. This way, the 16k prom image can be loaded into memory,
- and then the 3c905b driver can set the temporary configuration of the
- card to an appropriate value, either configurable by the user or chosen
- by the driver.
-
- To enable the 3c905B bugfix, which is necessary for these cards when
- booting from the Flash ROM, define -DCFG_3C90X_BOOTROM_FIX when building,
- create a floppy image and boot it once.
- Thereafter, the card should accept the larger prom image.
-
- The driver should choose an appropriate transceiver on the card. However,
- if it doesn't on your card or if you need to, for instance, set your
- card to 10mbps when connected to an unmanaged 10/100 hub, you can specify
- which transceiver you want to use. To do this, build the 3c905b.fd0
- image with -DCFG_3C90X_XCVR=x, where 'x' is one of the following
- values:
-
- 0 10Base-T
- 1 10mbps AUI
- 3 10Base-2 (thinnet/coax)
- 4 100Base-TX
- 5 100Base-FX
- 6 MII
- 8 Auto-negotiation 10Base-T / 100Base-TX (usually the default)
- 9 MII External MAC Mode
- 255 Allow driver to choose an 'appropriate' media port.
-
- Then proceed from step 2 in the above 'general use' instructions. The
- .rom image can be built with CFG_3C90X_XCVR set to a value, but you
- normally don't want to do this, since it is easier to change the
- transceiver type by rebuilding a new floppy, changing the BIOS to floppy
- boot, booting, and then changing the BIOS back to network boot. If
- CFG_3C90X_XCVR is not set in a particular build, it just uses the
- current configuration (either its 'best guess' or whatever the stored
- CFG_3C90X_XCVR value was from the last time it was set).
-
- [[ Note for the more technically inclined: The CFG_3C90X_XCVR value is
- programmed into a register in the card's NVRAM that was reserved for
- LanWorks PROM images to use. When the driver boots, the card comes
- up in MII mode, and the driver checks the LanWorks register to find
- out if the user specified a transceiver type. If it finds that
- information, it uses that, otherwise it picks a transceiver that the
- card has based on the 3c905b's MediaOptions register. This driver isn't
- quite smart enough to always determine which media port is actually
- _connected_; maybe someone else would like to take on that task (it
- actually involves sending a self-directed packet and seeing if it
- comes back. IF it does, that port is connected). ]]
-
- Another issue to keep in mind is that it is possible that some OS'es
- might not be happy with the way I've handled the PROM-image hack with
- setting MII mode on bootup. Linux 2.0.35 does not have this problem.
- Behavior of other systems may vary. The 3com documentation specifically
- says that, at least with the card that I have, the device driver in the
- OS should auto-select the media port, so other drivers should work fine
- with this 'hack'. However, if yours doesn't seem to, you can try defining
- CFG_3C90X_PRESERVE_XCVR when building to cause Etherboot to keep the
- working setting (that allowed the bootp/tftp process) across the eth_reset
- operation.
-
-
-IV FOR DEVELOPERS....
-
- If you would like to fix/extend/etc. this driver, feel free to do so; just
- be sure you can test the modified version on the 3c905B-TX cards that the
- driver was originally designed for. This section of this document gives
- some information that might be relevant to a programmer.
-
- A. Main Entry Point
-
- a3c90x_probe is the main entry point for this driver. It is referred
- to in an array in 'config.c'.
-
- B. Other Important Functions
-
- The functions a3c90x_transmit, a3c90x_poll, a3c90x_reset, and
- a3c90x_disable are static functions that EtherBoot finds out about
- as a result of a3c90x_probe setting entries in the nic structure
- for them. The EtherBoot framework does not use interrupts. It is
- polled. All transmit and receive operations are initiated by the
- etherboot framework, not by an interrupt or by the driver.
-
- C. Internal Functions
-
- The following functions are internal to the driver:
-
- a3c90x_internal_IssueCommand - sends a command to the 3c905b card.
- a3c90x_internal_SetWindow - shifts between one of eight register
- windows onboard the 3c90x. The bottom 16 bytes of the card's
- I/O space are multiplexed among 128 bytes, only 16 of which are
- visible at any one time. This SetWindow function selects one of
- the eight sets.
- a3c90x_internal_ReadEeprom - reads a word (16 bits) from the
- card's onboard nvram. This is NOT the BIOS boot rom. This is
- where the card stores such things as its hardware address.
- a3c90x_internal_WriteEeprom - writes a word (16 bits) to the
- card's nvram, and recomputes the eeprom checksum.
- a3c90x_internal_WriteEepromWord - writes a word (16 bits) to the
- card's nvram. Used by the above routine.
- a3c90x_internal_WriteEepromWord - writes a word (16 bits) to the
- card's nvram. Used by the above routine.
-
- D. Globals
-
- All global variables are inside a global structure named INF_3C90X.
- So, wherever you see that structure referenced, you know the variable
- is a global. Just keeps things a little neater.
-
- E. Enumerations
-
- There are quite a few enumerated type definitions for registers and
- so forth, many for registers that I didn't even touch in the driver.
- Register types start with 'reg', window numbers (for SetWindow)
- start with 'win', and commands (for IssueCommand) start with 'cmd'.
- Register offsets also include an indication in the name as to the
- size of the register (_b = byte, _w = word, _l = long), and which
- window the register is in, if it is windowed (0-7).
-
- F. Why the 'a3c90x' name?
-
- I had to come up with a letter at the beginning of all of the
- identifiers, since 3com so conveniently had their name start with a
- number. Another driver used 't' (for 'three'?); I chose 'a' for
- no reason at all.
-
-Addendum by Jorge L. deLyra <delyra@latt.if.usp.br>, 22Nov2000 re
-working around the 3C905 hardware bug mentioned above:
-
-Use this floppy to fix any 3COM model 3C905B PCI 10/100 Ethernet cards
-that fail to load and run the boot program the first time around. If
-they have a "Lucent" rather than a "Broadcom" chipset these cards have
-a configuration bug that causes a hang when trying to load the boot
-program from the PROM, if you try to use them right out of the box.
-
-The boot program in this floppy is the file named 3c905b-tpo100.rom
-from Etherboot version 4.6.10, compiled with the bugfix parameter
-
- CFG_3C90X_BOOTROM_FIX
-
-You have to take the chip off the card and boot the system once using
-this floppy. Once loaded from the floppy, the boot program will access
-the card and change some setting in it, correcting the problem. After
-that you may use either this boot program or the normal one, compiled
-without this bugfix parameter, to boot the machine from the PROM chip.
-
-[Any recent Etherboot version should do, not just 4.6.10 - Ed.]

-/* cs89x0.c: A Crystal Semiconductor CS89[02]0 driver for etherboot. */
-/*
- Permission is granted to distribute the enclosed cs89x0.[ch] driver
- only in conjunction with the Etherboot package. The code is
- ordinarily distributed under the GPL.
-
- Russ Nelson, January 2000
-
- ChangeLog:
-
- Thu Dec 6 22:40:00 1996 Markus Gutschke <gutschk@math.uni-muenster.de>
-
- * disabled all "advanced" features; this should make the code more reliable
-
- * reorganized the reset function
-
- * always reset the address port, so that autoprobing will continue working
-
- * some cosmetic changes
-
- * 2.5
-
- Thu Dec 5 21:00:00 1996 Markus Gutschke <gutschk@math.uni-muenster.de>
-
- * tested the code against a CS8900 card
-
- * lots of minor bug fixes and adjustments
-
- * this is the first release, that actually works! it still requires some
- changes in order to be more tolerant to different environments
-
- * 4
-
- Fri Nov 22 23:00:00 1996 Markus Gutschke <gutschk@math.uni-muenster.de>
-
- * read the manuals for the CS89x0 chipsets and took note of all the
- changes that will be neccessary in order to adapt Russel Nelson's code
- to the requirements of a BOOT-Prom
-
- * 6
-
- Thu Nov 19 22:00:00 1996 Markus Gutschke <gutschk@math.uni-muenster.de>
-
- * Synched with Russel Nelson's current code (v1.00)
-
- * 2
-
- Thu Nov 12 18:00:00 1996 Markus Gutschke <gutschk@math.uni-muenster.de>
-
- * Cleaned up some of the code and tried to optimize the code size.
-
- * 1.5
-
- Sun Nov 10 16:30:00 1996 Markus Gutschke <gutschk@math.uni-muenster.de>
-
- * First experimental release. This code compiles fine, but I
- have no way of testing whether it actually works.
-
- * I did not (yet) bother to make the code 16bit aware, so for
- the time being, it will only work for Etherboot/32.
-
- * 12

- DE101
- DE200 Turbo
- DE201 Turbo
- DE202 Turbo (TP BNC)
- DE210
- DE422 (EISA)
-
- The driver has been tested on DE100, DE200 and DE202 cards in a
- relatively busy network. The DE422 has been tested a little.
-
- This driver will NOT work for the DE203, DE204 and DE205 series of
- cards, since they have a new custom ASIC in place of the AMD LANCE
- chip. See the 'ewrk3.c' driver in the Linux source tree for running
- those cards.
-
- I have benchmarked the driver with a DE100 at 595kB/s to (542kB/s from)
- a DECstation 5000/200.

-
-
- Peter Bauer's depca.c (V0.5) was referred to when debugging V0.1 of this
- driver.
-
- The original DEPCA card requires that the ethernet ROM address counter
- be enabled to count and has an 8 bit NICSR. The ROM counter enabling is
- only done when a 0x08 is read as the first address octet (to minimise
- the chances of writing over some other hardware's I/O register). The
- NICSR accesses have been changed to byte accesses for all the cards
- supported by this driver, since there is only one useful bit in the MSB
- (remote boot timeout) and it is not used. Also, there is a maximum of
- only 48kB network RAM for this card. My thanks to Torbjorn Lindh for
- help debugging all this (and holding my feet to the fire until I got it
- right).
-
- The DE200 series boards have on-board 64kB RAM for use as a shared
- memory network buffer. Only the DE100 cards make use of a 2kB buffer
- mode which has not been implemented in this driver (only the 32kB and
- 64kB modes are supported [16kB/48kB for the original DEPCA]).
-
- At the most only 2 DEPCA cards can be supported on the ISA bus because
- there is only provision for two I/O base addresses on each card (0x300
- and 0x200). The I/O address is detected by searching for a byte sequence
- in the Ethernet station address PROM at the expected I/O address for the
- Ethernet PROM. The shared memory base address is 'autoprobed' by
- looking for the self test PROM and detecting the card name. When a
- second DEPCA is detected, information is placed in the base_addr
- variable of the next device structure (which is created if necessary),
- thus enabling ethif_probe initialization for the device. More than 2
- EISA cards can be supported, but care will be needed assigning the
- shared memory to ensure that each slot has the correct IRQ, I/O address
- and shared memory address assigned.
-
- ************************************************************************
-
- NOTE: If you are using two ISA DEPCAs, it is important that you assign
- the base memory addresses correctly. The driver autoprobes I/O 0x300
- then 0x200. The base memory address for the first device must be less
- than that of the second so that the auto probe will correctly assign the
- I/O and memory addresses on the same card. I can't think of a way to do
- this unambiguously at the moment, since there is nothing on the cards to
- tie I/O and memory information together.
-
- I am unable to test 2 cards together for now, so this code is
- unchecked. All reports, good or bad, are welcome.
-
- ************************************************************************
-
- The board IRQ setting must be at an unused IRQ which is auto-probed
- using Donald Becker's autoprobe routines. DEPCA and DE100 board IRQs are
- {2,3,4,5,7}, whereas the DE200 is at {5,9,10,11,15}. Note that IRQ2 is
- really IRQ9 in machines with 16 IRQ lines.
-
- No 16MB memory limitation should exist with this driver as DMA is not
- used and the common memory area is in low memory on the network card (my
- current system has 20MB and I've not had problems yet).
-
- The ability to load this driver as a loadable module has been added. To
- utilise this ability, you have to do <8 things:
-
- 0) have a copy of the loadable modules code installed on your system.
- 1) copy depca.c from the /linux/drivers/net directory to your favourite
- temporary directory.
- 2) if you wish, edit the source code near line 1530 to reflect the I/O
- address and IRQ you're using (see also 5).
- 3) compile depca.c, but include -DMODULE in the command line to ensure
- that the correct bits are compiled (see end of source code).
- 4) if you are wanting to add a new card, goto 5. Otherwise, recompile a
- kernel with the depca configuration turned off and reboot.
- 5) insmod depca.o [irq=7] [io=0x200] [mem=0xd0000] [adapter_name=DE100]
- [Alan Cox: Changed the code to allow command line irq/io assignments]
- [Dave Davies: Changed the code to allow command line mem/name
- assignments]
- 6) run the net startup bits for your eth?? interface manually
- (usually /etc/rc.inet[12] at boot time).
- 7) enjoy!
-
- Note that autoprobing is not allowed in loadable modules - the system is
- already up and running and you're messing with interrupts.
-
- To unload a module, turn off the associated interface
- 'ifconfig eth?? down' then 'rmmod depca'.
-
- To assign a base memory address for the shared memory when running as a
- loadable module, see 5 above. To include the adapter name (if you have
- no PROM but know the card name) also see 5 above. Note that this last
- option will not work with kernel built-in depca's.
-
- The shared memory assignment for a loadable module makes sense to avoid
- the 'memory autoprobe' picking the wrong shared memory (for the case of
- 2 depca's in a PC).
-
- ************************************************************************
- Support for MCA EtherWORKS cards added 11-3-98.
- Verified to work with up to 2 DE212 cards in a system (although not
- fully stress-tested).
-
- Currently known bugs/limitations:
-
- Note: with the MCA stuff as a module, it trusts the MCA configuration,
- not the command line for IRQ and memory address. You can
- specify them if you want, but it will throw your values out.
- You still have to pass the IO address it was configured as
- though.

-Etherboot - BOOTP/TFTP Bootstrap Program
-Intel EEPRO/10 NIC driver for Etherboot
-Adapted from Linux eepro.c from kernel 2.2.17
-
-This board accepts a 32 pin EEPROM (29C256), however a test with a
-27C010 shows that this EPROM also works in the socket, but it's not clear
-how repeatably. The two top address pins appear to be held low, thus
-the bottom 32kB of the 27C010 is visible in the CPU's address space.
-To be sure you could put 4 copies of the code in the 27C010, then
-it doesn't matter whether the extra lines are held low or high, just
-hopefully not floating as CMOS chips don't like floating inputs.
-
-Be careful with seating the EPROM as the socket on my board actually
-has 34 pins, the top row of 2 are not used.

- program space than initializing the individual tables, and I feel it's much

- 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 currently use one transmit buffer starting at TX_BUF_START (0x0100), and
- use the rest of memory, from RX_BUF_START to RX_BUF_END, for Rx buffers.

- Some code fragments were taken from verious places,
- Ken Yap's etherboot, FreeBSD's if_de.c, and various
- Linux related files. DEC's manuals for the 21143 and
- SROM format were very helpful. The Linux de driver
- development page has a number of links to useful

-How I added the SIS900 card to Etherboot
-
-Author: Marty Connor (mdc@thinguin.org)
-
-Date: 25 Febrary 2001
-
-Description:
-
-This file is intended to help people who want to write an Etherboot
-driver or port another driver to Etherboot. It is a starting point.
-Perhaps someday I may write a more detailed description of writing an
-Etherboot driver. This text should help get people started, and
-studying sis900.[ch] should help show the basic structure and
-techniques involved in writing and Etherboot driver.
-
-***********************************************************************
-
-0. Back up all the files I need to modify:
-
-cd etherboot-4.7.20/src
-cp Makefile Makefile.orig
-cp config.c config.c.orig
-cp pci.h pci.h.orig
-cp NIC NIC.orig
-cp cards.h cards.h.orig
-
-1. Edit src/Makefile to add SIS900FLAGS to defines
-
-SIS900FLAGS= -DINCLUDE_SIS900
-
-2. edit src/pci.h to add PCI signatures for card
-
-#define PCI_VENDOR_ID_SIS 0x1039
-#define PCI_DEVICE_ID_SIS900 0x0900
-#define PCI_DEVICE_ID_SIS7016 0x7016
-
-3. Edit src/config.c to add the card to the card probe list
-
-#if defined(INCLUDE_NS8390) || defined(INCLUDE_EEPRO100) ||
- defined(INCLUDE_LANCE) || defined(INCLUDE_EPIC100) ||
- defined(INCLUDE_TULIP) || defined(INCLUDE_OTULIP) ||
- defined(INCLUDE_3C90X) || defined(INCLUDE_3C595) ||
- defined(INCLUDE_RTL8139) || defined(INCLUDE_VIA_RHINE) ||
- defined(INCLUDE_SIS900) || defined(INCLUDE_W89C840)
-
-... and ...
-
-#ifdef INCLUDE_SIS900
- { PCI_VENDOR_ID_SIS, PCI_DEVICE_ID_SIS900,
- "SIS900", 0, 0, 0, 0},
- { PCI_VENDOR_ID_SIS, PCI_DEVICE_ID_SIS7016,
- "SIS7016", 0, 0, 0, 0},
-#endif
-
-... and ...
-
-#ifdef INCLUDE_SIS900
- { "SIS900", sis900_probe, pci_ioaddrs },
-#endif
-
-4. Edit NIC to add sis900 and sis7016 to NIC list
-
-# SIS 900 and SIS 7016
-sis900 sis900 0x1039,0x0900
-sis7016 sis900 0x1039,0x7016
-
-5. Edit cards.h to add sis900 probe routine declaration
-
-#ifdef INCLUDE_SIS900
-extern struct nic *sis900_probe(struct nic *, unsigned short *
- PCI_ARG(struct pci_device *));
-#endif
-
-***********************************************************************
-
-At this point, you can begin creating your driver source file. See
-the "Writing and Etherboot Driver" section of the Etherboot
-documentation for some hints. See the skel.c file for a starting
-point. If there is a Linux driver for the card, you may be able to
-use that. Copy and learn from existing Etherboot drivers (this is GPL
-/ Open Source software!).
-
-Join the etherboot-developers and etherboot-users mailing lists
-(information is on etherboot.sourceforge.net) for information and
-assistance. We invite more developers to help improve Etherboot.
-
-Visit the http://etherboot.sourceforge.net, http://thinguin.org,
-http://rom-o-matic.net, and http://ltsp.org sites for information and
-assistance.
-
-Enjoy.

+/* There are two ways to manage the TX descriptors on the tigon3.
+ * Either the descriptors are in host DMA'able memory, or they
+ * exist only in the cards on-chip SRAM. All 16 send bds are under
+ * the same mode, they may not be configured individually.
+ *
+ * The mode we use is controlled by TG3_FLAG_HOST_TXDS in tp->tg3_flags.
+ *
+ * To use host memory TX descriptors:
+ * 1) Set GRC_MODE_HOST_SENDBDS in GRC_MODE register.
+ * Make sure GRC_MODE_4X_NIC_SEND_RINGS is clear.
+ * 2) Allocate DMA'able memory.
+ * 3) In NIC_SRAM_SEND_RCB (of desired index) of on-chip SRAM:
+ * a) Set TG3_BDINFO_HOST_ADDR to DMA address of memory
+ * obtained in step 2
+ * b) Set TG3_BDINFO_NIC_ADDR to NIC_SRAM_TX_BUFFER_DESC.
+ * c) Set len field of TG3_BDINFO_MAXLEN_FLAGS to number
+ * of TX descriptors. Leave flags field clear.
+ * 4) Access TX descriptors via host memory. The chip
+ * will refetch into local SRAM as needed when producer
+ * index mailboxes are updated.
+ *
+ * To use on-chip TX descriptors:
+ * 1) Set GRC_MODE_4X_NIC_SEND_RINGS in GRC_MODE register.
+ * Make sure GRC_MODE_HOST_SENDBDS is clear.
+ * 2) In NIC_SRAM_SEND_RCB (of desired index) of on-chip SRAM:
+ * a) Set TG3_BDINFO_HOST_ADDR to zero.
+ * b) Set TG3_BDINFO_NIC_ADDR to NIC_SRAM_TX_BUFFER_DESC
+ * c) TG3_BDINFO_MAXLEN_FLAGS is don't care.
+ * 3) Access TX descriptors directly in on-chip SRAM

- * Change History
- *
- * Tigran Aivazian <tigran@sco.com>: TLan_PciProbe() now uses
- * new PCI BIOS interface.
- * Alan Cox <alan@redhat.com>: Fixed the out of memory
- * handling.
- *
- * Torben Mathiasen <torben.mathiasen@compaq.com> New Maintainer!
- *
- * v1.1 Dec 20, 1999 - Removed linux version checking
- * Patch from Tigran Aivazian.
- * - v1.1 includes Alan's SMP updates.
- * - We still have problems on SMP though,
- * but I'm looking into that.
- *
- * v1.2 Jan 02, 2000 - Hopefully fixed the SMP deadlock.
- * - Removed dependency of HZ being 100.
- * - We now allow higher priority timers to
- * overwrite timers like TLAN_TIMER_ACTIVITY
- * Patch from John Cagle <john.cagle@compaq.com>.
- * - Fixed a few compiler warnings.
- *
- * v1.3 Feb 04, 2000 - Fixed the remaining HZ issues.
- * - Removed call to pci_present().
- * - Removed SA_INTERRUPT flag from irq handler.
- * - Added __init and __initdata to reduce resisdent
- * code size.
- * - Driver now uses module_init/module_exit.
- * - Rewrote init_module and tlan_probe to
- * share a lot more code. We now use tlan_probe
- * with builtin and module driver.
- * - Driver ported to new net API.
- * - tlan.txt has been reworked to reflect current
- * driver (almost)
- * - Other minor stuff
- *
- * v1.4 Feb 10, 2000 - Updated with more changes required after Dave's
- * network cleanup in 2.3.43pre7 (Tigran & myself)
- * - Minor stuff.
- *
- * v1.5 March 22, 2000 - Fixed another timer bug that would hang the driver
- * if no cable/link were present.
- * - Cosmetic changes.
- * - TODO: Port completely to new PCI/DMA API
- * Auto-Neg fallback.
- *
- * v1.6 April 04, 2000 - Fixed driver support for kernel-parameters. Haven't
- * tested it though, as the kernel support is currently
- * broken (2.3.99p4p3).
- * - Updated tlan.txt accordingly.
- * - Adjusted minimum/maximum frame length.
- * - There is now a TLAN website up at
- * http://tlan.kernel.dk
- *
- * v1.7 April 07, 2000 - Started to implement custom ioctls. Driver now
- * reports PHY information when used with Donald
- * Beckers userspace MII diagnostics utility.
- *
- * v1.8 April 23, 2000 - Fixed support for forced speed/duplex settings.
- * - Added link information to Auto-Neg and forced
- * modes. When NIC operates with auto-neg the driver
- * will report Link speed & duplex modes as well as
- * link partner abilities. When forced link is used,
- * the driver will report status of the established
- * link.
- * Please read tlan.txt for additional information.
- * - Removed call to check_region(), and used
- * return value of request_region() instead.
- *
- * v1.8a May 28, 2000 - Minor updates.
- *
- * v1.9 July 25, 2000 - Fixed a few remaining Full-Duplex issues.
- * - Updated with timer fixes from Andrew Morton.
- * - Fixed module race in TLan_Open.
- * - Added routine to monitor PHY status.
- * - Added activity led support for Proliant devices.
- *
- * v1.10 Aug 30, 2000 - Added support for EISA based tlan controllers
- * like the Compaq NetFlex3/E.
- * - Rewrote tlan_probe to better handle multiple
- * bus probes. Probing and device setup is now
- * done through TLan_Probe and TLan_init_one. Actual
- * hardware probe is done with kernel API and
- * TLan_EisaProbe.
- * - Adjusted debug information for probing.
- * - Fixed bug that would cause general debug information
- * to be printed after driver removal.
- * - Added transmit timeout handling.
- * - Fixed OOM return values in tlan_probe.
- * - Fixed possible mem leak in tlan_exit
- * (now tlan_remove_one).
- * - Fixed timer bug in TLan_phyMonitor.
- * - This driver version is alpha quality, please
- * send me any bug issues you may encounter.
- *
- * v1.11 Aug 31, 2000 - Do not try to register irq 0 if no irq line was
- * set for EISA cards.
- * - Added support for NetFlex3/E with nibble-rate
- * 10Base-T PHY. This is untestet as I haven't got
- * one of these cards.
- * - Fixed timer being added twice.
- * - Disabled PhyMonitoring by default as this is
- * work in progress. Define MONITOR to enable it.
- * - Now we don't display link info with PHYs that
- * doesn't support it (level1).
- * - Incresed tx_timeout beacuse of auto-neg.
- * - Adjusted timers for forced speeds.
- *
- * v1.12 Oct 12, 2000 - Minor fixes (memleak, init, etc.)
- *
- * v1.13 Nov 28, 2000 - Stop flooding console with auto-neg issues
- * when link can't be established.
- * - Added the bbuf option as a kernel parameter.
- * - Fixed ioaddr probe bug.
- * - Fixed stupid deadlock with MII interrupts.
- * - Added support for speed/duplex selection with
- * multiple nics.
- * - Added partly fix for TX Channel lockup with
- * TLAN v1.0 silicon. This needs to be investigated
- * further.
- *
- * v1.14 Dec 16, 2000 - Added support for servicing multiple frames per.
- * interrupt. Thanks goes to
- * Adam Keys <adam@ti.com>
- * Denis Beaudoin <dbeaudoin@ti.com>
- * for providing the patch.
- * - Fixed auto-neg output when using multiple
- * adapters.
- * - Converted to use new taskq interface.
- *
- * v1.14a Jan 6, 2001 - Minor adjustments (spinlocks, etc.)
- *

- * This function handles timed functionality for the

- * delaying for autonegotionation and driving the ACT LED.
- * - Autonegotiation requires being allowed about
- * 2 1/2 seconds before attempting to transmit a
- * packet. It would be a very bad thing to hang
- * the kernel this long, so the driver doesn't
- * allow transmission 'til after this time, for
- * certain PHYs. It would be much nicer if all
- * PHYs were interrupt-capable like the internal
- * PHY.
- * - The ACT LED, which shows adapter activity, is
- * driven by the driver, and so must be left on
- * for a short period to power up the LED so it
- * can be seen. This delay can be changed by
- * changing the TLAN_TIMER_ACT_DELAY in tlan.h,
- * if desired. 100 ms produces a slightly
- * sluggish response.
+ * This function uses the TLAN's MII bus to retreive the contents

-
-This is a tulip and clone driver for Etherboot. See the revision
-history in the tulip.c file for information on changes. This version
-of the driver incorporates changes from Bob Edwards and Paul Mackerras
-who cantributed changes to support the TRENDnet TE100-PCIA NIC which
-uses a genuine Intel 21143-PD chipset. There are also various code
-cleanups to make time-based activities more reliable.
-
-Of course you have to have all the usual Etherboot environment
-(bootp/dhcp/NFS) set up, and you need a Linux kernel with v0.91g
-(7.16.99) or later of the tulip.c driver compiled in to support some
-MX98715 based cards. That file is available at:
-
- http://cesdis.gsfc.nasa.gov/linux/drivers/test/tulip.c
-
-NOTES
-
-I've tested this driver with a SOHOware Fast 10/100 Model SDA110A,
-a Linksys LNE100TX v2.0, and a Netgear FA310TX card, and it worked at
-both 10 and 100 mbits. Other cards based on the tulip family may work as
-well.
-
-These cards are about 20$US, are supported by Linux and now Etherboot,
-and being PCI, they auto-configure IRQ and IOADDR and auto-negotiate
-10/100 half/full duplex. It seems like a pretty good value compared to
-some of the pricier cards, and can lower the cost of building/adapting
-thin client workstations substantially while giving a considerable
-performance increase.
-
-On some PCI tulip clone chipsets (MX987x5, LC82C115, LC82C168) this driver
-lets the card choose the fastest speed it can negotiate with the peer
-device. On other cards, it chooses 10mbit half-duplex.
-
-I burned an AM27C256 (32KByte) EPROM with mx987x5.lzrom and it worked.
-According to the data sheet the MX98715A supports up to 64K (27C512)
-EPROMs,
-
-I've liberally commented the code and header files in the hope that it
-will help the next person who hacks the code or needs to support some
-tulip clone card, or wishes to add functionality.
-
-Anyway, please test this if you can on your tulip based card, and let
-me (mdc@thinguin.org) and the netboot list (netboot@baghira.han.de)
-know how things go. I also would appreciate code review by people who
-program. I'm a strong believer in "another set of eyes".
-

-
