-
- The E2100 series ethercard is a fairly generic shared memory 8390
- implementation. The only unusual aspect is the way the shared memory
- registers are set: first you do an inb() in what is normally the
- station address region, and the low three bits of next outb() *address*
- is used as the write value for that register. Either someone wasn't
- too used to dem bit en bites, or they were trying to obfuscate the
- programming interface.
-
- There is an additional complication when setting the window on the packet
- buffer. You must first do a read into the packet buffer region with the
- low 8 address bits the address setting the page for the start of the packet
- buffer window, and then do the above operation. See mem_on() for details.
-
- One bug on the chip is that even a hard reset won't disable the memory
- window, usually resulting in a hung machine if mem_off() isn't called.
- If this happens, you must power down the machine for about 30 seconds.

-
- Information and Code Sources:
-
- 1) The existing myriad of Linux 8390 drivers written by Donald Becker.
-
- 2) Once again Russ Nelson's asm packet driver provided additional info.
-
- 3) Info for getting IRQ and sh-mem gleaned from the EISA cfg files.
- Too bad it doesn't work -- see below.
-
- The ES3210 is an EISA shared memory NS8390 implementation. Note
- that all memory copies to/from the board must be 32bit transfers.
- Which rules out using eth_io_copy_and_sum() in this driver.
-
- Apparently there are two slightly different revisions of the
- card, since there are two distinct EISA cfg files (!rii0101.cfg
- and !rii0102.cfg) One has media select in the cfg file and the
- other doesn't. Hopefully this will work with either.
-
- That is about all I can tell you about it, having never actually
- even seen one of these cards. :) Try http://www.interlan.com
- if you want more info.
-
- Thanks go to Mark Salazar for testing v0.02 of this driver.
-
- Bugs, to-fix, etc:
-
- 1) The EISA cfg ports that are *supposed* to have the IRQ and shared
- mem values just read 0xff all the time. Hrrmpf. Apparently the
- same happens with the packet driver as the code for reading
- these registers is disabled there. In the meantime, boot with:
- ether=<IRQ>,0,0x<shared_mem_addr>,eth0 to override the IRQ and
- shared memory detection. (The i/o port detection is okay.)
-
- 2) Module support currently untested. Probably works though.

+ A PCMCIA ethernet driver for Asix AX88190-based cards
+
+ The Asix AX88190 is a NS8390-derived chipset with a few nasty
+ idiosyncracies that make it very inconvenient to support with a
+ standard 8390 driver. This driver is based on pcnet_cs, with the
+ tweaked 8390 code grafted on the end. Much of what I did was to
+ clean up and update a similar driver supplied by Asix, which was
+ adapted by William Lee, william@asix.com.tw.

+ This is the chip-specific code for many 8390-based ethernet adaptors.
+ This is not a complete driver, it must be combined with board-specific
+ code such as ne.c, wd.c, 3c503.c, etc.
+
+ Seeing how at least eight drivers use this code, (not counting the
+ PCMCIA ones either) it is easy to break some card by what seems like
+ a simple innocent change. Please contact me or Donald if you think
+ you have found something that needs changing. -- PG
+
+ Changelog:
+
+ Paul Gortmaker : remove set_bit lock, other cleanups.
+ Paul Gortmaker : add ei_get_8390_hdr() so we can pass skb's to
+ ei_block_input() for eth_io_copy_and_sum().
+ Paul Gortmaker : exchange static int ei_pingpong for a #define,
+ also add better Tx error handling.
+ Paul Gortmaker : rewrite Rx overrun handling as per NS specs.
+ Alexey Kuznetsov : use the 8390's six bit hash multicast filter.
+ Paul Gortmaker : tweak ANK's above multicast changes a bit.
+ Paul Gortmaker : update packet statistics for v2.1.x
+ Alan Cox : support arbitrary stupid port mappings on the
+ 68K Macintosh. Support >16bit I/O spaces
+ Paul Gortmaker : add kmod support for auto-loading of the 8390
+ module by all drivers that require it.
+ Alan Cox : Spinlocking work, added 'BUG_83C690'
+ Paul Gortmaker : Separate out Tx timeout code from Tx path.

+ * SMP and the 8390 setup.
+ *
+ * The 8390 isn't exactly designed to be multithreaded on RX/TX. There is
+ * a page register that controls bank and packet buffer access. We guard
+ * this with ei_local->page_lock. Nobody should assume or set the page other
+ * than zero when the lock is not held. Lock holders must restore page 0
+ * before unlocking. Even pure readers must take the lock to protect in
+ * page 0.
+ *
+ * To make life difficult the chip can also be very slow. We therefore can't
+ * just use spinlocks. For the longer lockups we disable the irq the device
+ * sits on and hold the lock. We must hold the lock because there is a dual
+ * processor case other than interrupts (get stats/set multicast list in
+ * parallel with each other and transmit).
+ *
+ * Note: in theory we can just disable the irq on the card _but_ there is
+ * a latency on SMP irq delivery. So we can easily go "disable irq" "sync irqs"
+ * enter lock, take the queued irq. So we waddle instead of flying.

+
+ The E2100 series ethercard is a fairly generic shared memory 8390
+ implementation. The only unusual aspect is the way the shared memory
+ registers are set: first you do an inb() in what is normally the
+ station address region, and the low three bits of next outb() *address*
+ is used as the write value for that register. Either someone wasn't
+ too used to dem bit en bites, or they were trying to obfuscate the
+ programming interface.
+
+ There is an additional complication when setting the window on the packet
+ buffer. You must first do a read into the packet buffer region with the
+ low 8 address bits the address setting the page for the start of the packet
+ buffer window, and then do the above operation. See mem_on() for details.
+
+ One bug on the chip is that even a hard reset won't disable the memory
+ window, usually resulting in a hung machine if mem_off() isn't called.
+ If this happens, you must power down the machine for about 30 seconds.

+ Linux driver for Racal-Interlan ES3210 EISA Network Adapter
+
+ Copyright (C) 1996, Paul Gortmaker.
+
+ This software may be used and distributed according to the terms
+ of the GNU General Public License, incorporated herein by reference.
+
+ Information and Code Sources:
+
+ 1) The existing myriad of Linux 8390 drivers written by Donald Becker.
+
+ 2) Once again Russ Nelson's asm packet driver provided additional info.
+
+ 3) Info for getting IRQ and sh-mem gleaned from the EISA cfg files.
+ Too bad it doesn't work -- see below.
+
+ The ES3210 is an EISA shared memory NS8390 implementation. Note
+ that all memory copies to/from the board must be 32bit transfers.
+ Which rules out using eth_io_copy_and_sum() in this driver.
+
+ Apparently there are two slightly different revisions of the
+ card, since there are two distinct EISA cfg files (!rii0101.cfg
+ and !rii0102.cfg) One has media select in the cfg file and the
+ other doesn't. Hopefully this will work with either.
+
+ That is about all I can tell you about it, having never actually
+ even seen one of these cards. :) Try http://www.interlan.com
+ if you want more info.
+
+ Thanks go to Mark Salazar for testing v0.02 of this driver.
+
+ Bugs, to-fix, etc:
+
+ 1) The EISA cfg ports that are *supposed* to have the IRQ and shared
+ mem values just read 0xff all the time. Hrrmpf. Apparently the
+ same happens with the packet driver as the code for reading
+ these registers is disabled there. In the meantime, boot with:
+ ether=<IRQ>,0,0x<shared_mem_addr>,eth0 to override the IRQ and
+ shared memory detection. (The i/o port detection is okay.)
+
+ 2) Module support currently untested. Probably works though.

+ The HP EtherTwist chip implementation is a fairly routine DP8390
+ implementation. It allows both shared memory and programmed-I/O buffer
+ access, using a custom interface for both. The programmed-I/O mode is
+ entirely implemented in the HP EtherTwist chip, bypassing the problem
+ ridden built-in 8390 facilities used on NE2000 designs. The shared
+ memory mode is likewise special, with an offset register used to make
+ packets appear at the shared memory base. Both modes use a base and bounds
+ page register to hide the Rx ring buffer wrap -- a packet that spans the
+ end of physical buffer memory appears continuous to the driver. (c.f. the
+ 3c503 and Cabletron E2100)
+
+ A special note: the internal buffer of the board is only 8 bits wide.
+ This lays several nasty traps for the unaware:
+ - the 8390 must be programmed for byte-wide operations
+ - all I/O and memory operations must work on whole words (the access
+ latches are serially preloaded and have no byte-swapping ability).
+
+ This board is laid out in I/O space much like the earlier HP boards:
+ the first 16 locations are for the board registers, and the second 16 are
+ for the 8390. The board is easy to identify, with both a dedicated 16 bit
+ ID register and a constant 0x530* value in the upper bits of the paging
+ register.

+
+ This is the chip-specific code for many 8390-based ethernet adaptors.
+ This is not a complete driver, it must be combined with board-specific
+ code such as ne.c, wd.c, 3c503.c, etc.
+
+ Seeing how at least eight drivers use this code, (not counting the
+ PCMCIA ones either) it is easy to break some card by what seems like
+ a simple innocent change. Please contact me or Donald if you think
+ you have found something that needs changing. -- PG
+
+
+ Changelog:
+
+ Paul Gortmaker : remove set_bit lock, other cleanups.
+ Paul Gortmaker : add ei_get_8390_hdr() so we can pass skb's to
+ ei_block_input() for eth_io_copy_and_sum().
+ Paul Gortmaker : exchange static int ei_pingpong for a #define,
+ also add better Tx error handling.
+ Paul Gortmaker : rewrite Rx overrun handling as per NS specs.
+ Alexey Kuznetsov : use the 8390's six bit hash multicast filter.
+ Paul Gortmaker : tweak ANK's above multicast changes a bit.
+ Paul Gortmaker : update packet statistics for v2.1.x
+ Alan Cox : support arbitrary stupid port mappings on the
+ 68K Macintosh. Support >16bit I/O spaces
+ Paul Gortmaker : add kmod support for auto-loading of the 8390
+ module by all drivers that require it.
+ Alan Cox : Spinlocking work, added 'BUG_83C690'
+ Paul Gortmaker : Separate out Tx timeout code from Tx path.
+ Paul Gortmaker : Remove old unused single Tx buffer code.
+ Hayato Fujiwara : Add m32r support.
+ Paul Gortmaker : use skb_padto() instead of stack scratch area

+ * SMP and the 8390 setup.
+ *
+ * The 8390 isn't exactly designed to be multithreaded on RX/TX. There is
+ * a page register that controls bank and packet buffer access. We guard
+ * this with ei_local->page_lock. Nobody should assume or set the page other
+ * than zero when the lock is not held. Lock holders must restore page 0
+ * before unlocking. Even pure readers must take the lock to protect in
+ * page 0.
+ *
+ * To make life difficult the chip can also be very slow. We therefore can't
+ * just use spinlocks. For the longer lockups we disable the irq the device
+ * sits on and hold the lock. We must hold the lock because there is a dual
+ * processor case other than interrupts (get stats/set multicast list in
+ * parallel with each other and transmit).
+ *
+ * Note: in theory we can just disable the irq on the card _but_ there is
+ * a latency on SMP irq delivery. So we can easily go "disable irq" "sync irqs"
+ * enter lock, take the queued irq. So we waddle instead of flying.
+ *
+ * Finally by special arrangement for the purpose of being generally
+ * annoying the transmit function is called bh atomic. That places
+ * restrictions on the user context callers as disable_irq won't save
+ * them.
+ *
+ * Additional explanation of problems with locking by Alan Cox:
+ *
+ * "The author (me) didn't use spin_lock_irqsave because the slowness of the
+ * card means that approach caused horrible problems like losing serial data
+ * at 38400 baud on some chips. Remember many 8390 nics on PCI were ISA
+ * chips with FPGA front ends.
+ *
+ * Ok the logic behind the 8390 is very simple:
+ *
+ * Things to know
+ * - IRQ delivery is asynchronous to the PCI bus
+ * - Blocking the local CPU IRQ via spin locks was too slow
+ * - The chip has register windows needing locking work
+ *
+ * So the path was once (I say once as people appear to have changed it
+ * in the mean time and it now looks rather bogus if the changes to use
+ * disable_irq_nosync_irqsave are disabling the local IRQ)
+ *
+ *
+ * Take the page lock
+ * Mask the IRQ on chip
+ * Disable the IRQ (but not mask locally- someone seems to have
+ * broken this with the lock validator stuff)
+ * [This must be _nosync as the page lock may otherwise
+ * deadlock us]
+ * Drop the page lock and turn IRQs back on
+ *
+ * At this point an existing IRQ may still be running but we can't
+ * get a new one
+ *
+ * Take the lock (so we know the IRQ has terminated) but don't mask
+ * the IRQs on the processor
+ * Set irqlock [for debug]
+ *
+ * Transmit (slow as ****)
+ *
+ * re-enable the IRQ
+ *
+ *
+ * We have to use disable_irq because otherwise you will get delayed
+ * interrupts on the APIC bus deadlocking the transmit path.
+ *
+ * Quite hairy but the chip simply wasn't designed for SMP and you can't
+ * even ACK an interrupt without risking corrupting other parallel
+ * activities on the chip." [lkml, 25 Jul 2007]

+ BNC/AUI, but the "b" also has RJ-45 and selection is via the SCU.
+ The shared memory address selection is also slightly different.
+ Note that shared memory address > 1MB are supported with this driver.

+
+ This driver should work with many programmed-I/O 8390-based ethernet
+ boards. Currently it supports the NE1000, NE2000, many clones,
+ and some Cabletron products.
+
+ Changelog:
+
+ Paul Gortmaker : use ENISR_RDC to monitor Tx PIO uploads, made
+ sanity checks and bad clone support optional.
+ Paul Gortmaker : new reset code, reset card after probe at boot.
+ Paul Gortmaker : multiple card support for module users.
+ Paul Gortmaker : Support for PCI ne2k clones, similar to lance.c
+ Paul Gortmaker : Allow users with bad cards to avoid full probe.
+ Paul Gortmaker : PCI probe changes, more PCI cards supported.
+ rjohnson@analogic.com : Changed init order so an interrupt will only
+ occur after memory is allocated for dev->priv. Deallocated memory
+ last in cleanup_modue()
+ Richard Guenther : Added support for ISAPnP cards
+ Paul Gortmaker : Discontinued PCI support - use ne2k-pci.c instead.
+ Hayato Fujiwara : Add m32r support.

+
+ The author may be reached as wimpie@linux.cc.kuleuven.ac.be
+
+ Currently supported: NE/2
+ This patch was never tested on other MCA-ethernet adapters, but it
+ might work. Just give it a try and let me know if you have problems.
+ Also mail me if it really works, please!
+
+ Changelog:
+ Mon Feb 3 16:26:02 MET 1997
+ - adapted the driver to work with the 2.1.25 kernel
+ - multiple ne2 support (untested)
+ - module support (untested)
+
+ Fri Aug 28 00:18:36 CET 1998 (David Weinehall)
+ - fixed a few minor typos
+ - made the MODULE_PARM conditional (it only works with the v2.1.x kernels)
+ - fixed the module support (Now it's working...)
+
+ Mon Sep 7 19:01:44 CET 1998 (David Weinehall)
+ - added support for Arco Electronics AE/2-card (experimental)
+
+ Mon Sep 14 09:53:42 CET 1998 (David Weinehall)
+ - added support for Compex ENET-16MC/P (experimental)
+
+ Tue Sep 15 16:21:12 CET 1998 (David Weinehall, Magnus Jonsson, Tomas Ogren)
+ - Miscellaneous bugfixes
+
+ Tue Sep 19 16:21:12 CET 1998 (Magnus Jonsson)
+ - Cleanup
+
+ Wed Sep 23 14:33:34 CET 1998 (David Weinehall)
+ - Restructuring and rewriting for v2.1.x compliance
+
+ Wed Oct 14 17:19:21 CET 1998 (David Weinehall)
+ - Added code that unregisters irq and proc-info
+ - Version# bump
+
+ Mon Nov 16 15:28:23 CET 1998 (Wim Dumon)
+ - pass 'dev' as last parameter of request_irq in stead of 'NULL'
+
+ Wed Feb 7 21:24:00 CET 2001 (Alfred Arnold)
+ - added support for the D-Link DE-320CT
+
+ * WARNING
+ -------
+ This is alpha-test software. It is not guaranteed to work. As a
+ matter of fact, I'm quite sure there are *LOTS* of bugs in here. I
+ would like to hear from you if you use this driver, even if it works.
+ If it doesn't work, be sure to send me a mail with the problems !

+ 2) The existing myriad of other Linux 8390 drivers by Donald Becker.
+ 3) Info for getting IRQ and sh-mem gleaned from the EISA cfg file
+
+ The NE3210 is an EISA shared memory NS8390 implementation. Shared
+ memory address > 1MB should work with this driver.
+
+ Note that the .cfg file (3/11/93, v1.0) has AUI and BNC switched
+ around (or perhaps there are some defective/backwards cards ???)
+
+ This driver WILL NOT WORK FOR THE NE3200 - it is completely different
+ and does not use an 8390 at all.
+
+ Updated to EISA probing API 5/2003 by Marc Zyngier.

+/* smc-mca.c: A SMC Ultra ethernet driver for linux. */
+/*
+ Most of this driver, except for ultramca_probe is nearly
+ verbatim from smc-ultra.c by Donald Becker. The rest is
+ written and copyright 1996 by David Weis, weisd3458@uni.edu
+
+ This is a driver for the SMC Ultra and SMC EtherEZ ethercards.
+
+ This driver uses the cards in the 8390-compatible, shared memory mode.
+ Most of the run-time complexity is handled by the generic code in
+ 8390.c.
+
+ This driver enables the shared memory only when doing the actual data
+ transfers to avoid a bug in early version of the card that corrupted
+ data transferred by a AHA1542.
+
+ This driver does not support the programmed-I/O data transfer mode of
+ the EtherEZ. That support (if available) is smc-ez.c. Nor does it
+ use the non-8390-compatible "Altego" mode. (No support currently planned.)
+
+ Changelog:
+
+ Paul Gortmaker : multiple card support for module users.
+ David Weis : Micro Channel-ized it.
+ Tom Sightler : Added support for IBM PS/2 Ethernet Adapter/A
+ Christopher Turcksin : Changed MCA-probe so that multiple adapters are
+ found correctly (Jul 16, 1997)
+ Chris Beauregard : Tried to merge the two changes above (Dec 15, 1997)
+ Tom Sightler : Fixed minor detection bug caused by above merge
+ Tom Sightler : Added support for three more Western Digital
+ MCA-adapters
+ Tom Sightler : Added support for 2.2.x mca_find_unused_adapter
+ Hartmut Schmidt : - Modified parameter detection to handle each
+ card differently depending on a switch-list
+ - 'card_ver' removed from the adapter list
+ - Some minor bug fixes

+
+ This driver uses the cards in the 8390-compatible mode.
+ Most of the run-time complexity is handled by the generic code in
+ 8390.c. The code in this file is responsible for
+
+ ultra_probe() Detecting and initializing the card.
+ ultra_probe1()
+ ultra_probe_isapnp()
+
+ ultra_open() The card-specific details of starting, stopping
+ ultra_reset_8390() and resetting the 8390 NIC core.
+ ultra_close()
+
+ ultra_block_input() Routines for reading and writing blocks of
+ ultra_block_output() packet buffer memory.
+ ultra_pio_input()
+ ultra_pio_output()
+
+ This driver enables the shared memory only when doing the actual data
+ transfers to avoid a bug in early version of the card that corrupted
+ data transferred by a AHA1542.
+
+ This driver now supports the programmed-I/O (PIO) data transfer mode of
+ the EtherEZ. It does not use the non-8390-compatible "Altego" mode.
+ That support (if available) is in smc-ez.c.
+
+ Changelog:
+
+ Paul Gortmaker : multiple card support for module users.
+ Donald Becker : 4/17/96 PIO support, minor potential problems avoided.
+ Donald Becker : 6/6/96 correctly set auto-wrap bit.
+ Alexander Sotirov : 1/20/01 Added support for ISAPnP cards
+
+ Note about the ISA PnP support:
+
+ This driver can not autoprobe for more than one SMC EtherEZ PnP card.
+ You have to configure the second card manually through the /proc/isapnp
+ interface and then load the module with an explicit io=0x___ option.

+/* smc-ultra32.c: An SMC Ultra32 EISA ethernet driver for linux.
+
+Sources:
+
+ This driver is based on (cloned from) the ISA SMC Ultra driver
+ written by Donald Becker. Modifications to support the EISA
+ version of the card by Paul Gortmaker and Leonard N. Zubkoff.
+
+ This software may be used and distributed according to the terms
+ of the GNU General Public License, incorporated herein by reference.
+
+Theory of Operation:
+
+ The SMC Ultra32C card uses the SMC 83c790 chip which is also
+ found on the ISA SMC Ultra cards. It has a shared memory mode of
+ operation that makes it similar to the ISA version of the card.
+ The main difference is that the EISA card has 32KB of RAM, but
+ only an 8KB window into that memory. The EISA card also can be
+ set for a bus-mastering mode of operation via the ECU, but that
+ is not (and probably will never be) supported by this driver.
+ The ECU should be run to enable shared memory and to disable the
+ bus-mastering feature for use with linux.
+
+ By programming the 8390 to use only 8KB RAM, the modifications
+ to the ISA driver can be limited to the probe and initialization
+ code. This allows easy integration of EISA support into the ISA
+ driver. However, the driver development kit from SMC provided the
+ register information for sliding the 8KB window, and hence the 8390
+ is programmed to use the full 32KB RAM.
+
+ Unfortunately this required code changes outside the probe/init
+ routines, and thus we decided to separate the EISA driver from
+ the ISA one. In this way, ISA users don't end up with a larger
+ driver due to the EISA code, and EISA users don't end up with a
+ larger driver due to the ISA EtherEZ PIO code. The driver is
+ similar to the 3c503/16 driver, in that the window must be set
+ back to the 1st 8KB of space for access to the two 8390 Tx slots.
+
+ In testing, using only 8KB RAM (3 Tx / 5 Rx) didn't appear to
+ be a limiting factor, since the EISA bus could get packets off
+ the card fast enough, but having the use of lots of RAM as Rx
+ space is extra insurance if interrupt latencies become excessive.

-/*
- The HP EtherTwist chip implementation is a fairly routine DP8390
- implementation. It allows both shared memory and programmed-I/O buffer
- access, using a custom interface for both. The programmed-I/O mode is
- entirely implemented in the HP EtherTwist chip, bypassing the problem
- ridden built-in 8390 facilities used on NE2000 designs. The shared
- memory mode is likewise special, with an offset register used to make
- packets appear at the shared memory base. Both modes use a base and bounds
- page register to hide the Rx ring buffer wrap -- a packet that spans the
- end of physical buffer memory appears continuous to the driver. (c.f. the
- 3c503 and Cabletron E2100)
-
- A special note: the internal buffer of the board is only 8 bits wide.
- This lays several nasty traps for the unaware:
- - the 8390 must be programmed for byte-wide operations
- - all I/O and memory operations must work on whole words (the access
- latches are serially preloaded and have no byte-swapping ability).
-
- This board is laid out in I/O space much like the earlier HP boards:
- the first 16 locations are for the board registers, and the second 16 are
- for the 8390. The board is easy to identify, with both a dedicated 16 bit
- ID register and a constant 0x530* value in the upper bits of the paging
- register.

- This is the chip-specific code for many 8390-based ethernet adaptors.
- This is not a complete driver, it must be combined with board-specific
- code such as ne.c, wd.c, 3c503.c, etc.
-
- Seeing how at least eight drivers use this code, (not counting the
- PCMCIA ones either) it is easy to break some card by what seems like
- a simple innocent change. Please contact me or Donald if you think
- you have found something that needs changing. -- PG
-
-
- Changelog:
-
- Paul Gortmaker : remove set_bit lock, other cleanups.
- Paul Gortmaker : add ei_get_8390_hdr() so we can pass skb's to
- ei_block_input() for eth_io_copy_and_sum().
- Paul Gortmaker : exchange static int ei_pingpong for a #define,
- also add better Tx error handling.
- Paul Gortmaker : rewrite Rx overrun handling as per NS specs.
- Alexey Kuznetsov : use the 8390's six bit hash multicast filter.
- Paul Gortmaker : tweak ANK's above multicast changes a bit.
- Paul Gortmaker : update packet statistics for v2.1.x
- Alan Cox : support arbitrary stupid port mappings on the
- 68K Macintosh. Support >16bit I/O spaces
- Paul Gortmaker : add kmod support for auto-loading of the 8390
- module by all drivers that require it.
- Alan Cox : Spinlocking work, added 'BUG_83C690'
- Paul Gortmaker : Separate out Tx timeout code from Tx path.
- Paul Gortmaker : Remove old unused single Tx buffer code.
- Hayato Fujiwara : Add m32r support.
- Paul Gortmaker : use skb_padto() instead of stack scratch area

-/*
- * SMP and the 8390 setup.
- *
- * The 8390 isn't exactly designed to be multithreaded on RX/TX. There is
- * a page register that controls bank and packet buffer access. We guard
- * this with ei_local->page_lock. Nobody should assume or set the page other
- * than zero when the lock is not held. Lock holders must restore page 0
- * before unlocking. Even pure readers must take the lock to protect in
- * page 0.
- *
- * To make life difficult the chip can also be very slow. We therefore can't
- * just use spinlocks. For the longer lockups we disable the irq the device
- * sits on and hold the lock. We must hold the lock because there is a dual
- * processor case other than interrupts (get stats/set multicast list in
- * parallel with each other and transmit).
- *
- * Note: in theory we can just disable the irq on the card _but_ there is
- * a latency on SMP irq delivery. So we can easily go "disable irq" "sync irqs"
- * enter lock, take the queued irq. So we waddle instead of flying.
- *
- * Finally by special arrangement for the purpose of being generally
- * annoying the transmit function is called bh atomic. That places
- * restrictions on the user context callers as disable_irq won't save
- * them.
- *
- * Additional explanation of problems with locking by Alan Cox:
- *
- * "The author (me) didn't use spin_lock_irqsave because the slowness of the
- * card means that approach caused horrible problems like losing serial data
- * at 38400 baud on some chips. Remember many 8390 nics on PCI were ISA
- * chips with FPGA front ends.
- *
- * Ok the logic behind the 8390 is very simple:
- *
- * Things to know
- * - IRQ delivery is asynchronous to the PCI bus
- * - Blocking the local CPU IRQ via spin locks was too slow
- * - The chip has register windows needing locking work
- *
- * So the path was once (I say once as people appear to have changed it
- * in the mean time and it now looks rather bogus if the changes to use
- * disable_irq_nosync_irqsave are disabling the local IRQ)
- *
- *
- * Take the page lock
- * Mask the IRQ on chip
- * Disable the IRQ (but not mask locally- someone seems to have
- * broken this with the lock validator stuff)
- * [This must be _nosync as the page lock may otherwise
- * deadlock us]
- * Drop the page lock and turn IRQs back on
- *
- * At this point an existing IRQ may still be running but we can't
- * get a new one
- *
- * Take the lock (so we know the IRQ has terminated) but don't mask
- * the IRQs on the processor
- * Set irqlock [for debug]
- *
- * Transmit (slow as ****)
- *
- * re-enable the IRQ
- *
- *
- * We have to use disable_irq because otherwise you will get delayed
- * interrupts on the APIC bus deadlocking the transmit path.
- *
- * Quite hairy but the chip simply wasn't designed for SMP and you can't
- * even ACK an interrupt without risking corrupting other parallel
- * activities on the chip." [lkml, 25 Jul 2007]

- Information and Code Sources:
-
- 1) Based upon framework of es3210 driver.
- 2) The existing myriad of other Linux 8390 drivers by Donald Becker.
- 3) Russ Nelson's asm packet driver provided additional info.
- 4) Info for getting IRQ and sh-mem gleaned from the EISA cfg files.
-
- The LNE390 is an EISA shared memory NS8390 implementation. Note
- that all memory copies to/from the board must be 32bit transfers.
- There are two versions of the card: the lne390a and the lne390b.
- Going by the EISA cfg files, the "a" has jumpers to select between
- BNC/AUI, but the "b" also has RJ-45 and selection is via the SCU.
- The shared memory address selection is also slightly different.
- Note that shared memory address > 1MB are supported with this driver.
-
- You can try <http://www.mylex.com> if you want more info, as I've
- never even seen one of these cards. :)
-
- Arnaldo Carvalho de Melo <acme@conectiva.com.br> - 2000/09/01

-
- This driver should work with many programmed-I/O 8390-based ethernet
- boards. Currently it supports the NE1000, NE2000, many clones,
- and some Cabletron products.
-
- Changelog:
-
- Paul Gortmaker : use ENISR_RDC to monitor Tx PIO uploads, made
- sanity checks and bad clone support optional.
- Paul Gortmaker : new reset code, reset card after probe at boot.
- Paul Gortmaker : multiple card support for module users.
- Paul Gortmaker : Support for PCI ne2k clones, similar to lance.c
- Paul Gortmaker : Allow users with bad cards to avoid full probe.
- Paul Gortmaker : PCI probe changes, more PCI cards supported.
- rjohnson@analogic.com : Changed init order so an interrupt will only
- occur after memory is allocated for dev->priv. Deallocated memory
- last in cleanup_modue()
- Richard Guenther : Added support for ISAPnP cards
- Paul Gortmaker : Discontinued PCI support - use ne2k-pci.c instead.
- Hayato Fujiwara : Add m32r support.

-/* ne2.c: A NE/2 Ethernet Driver for Linux. */
-/*
- Based on the NE2000 driver written by Donald Becker (1992-94).
- modified by Wim Dumon (Apr 1996)
-
- This software may be used and distributed according to the terms
- of the GNU General Public License, incorporated herein by reference.
-
- The author may be reached as wimpie@linux.cc.kuleuven.ac.be
-
- Currently supported: NE/2
- This patch was never tested on other MCA-ethernet adapters, but it
- might work. Just give it a try and let me know if you have problems.
- Also mail me if it really works, please!
-
- Changelog:
- Mon Feb 3 16:26:02 MET 1997
- - adapted the driver to work with the 2.1.25 kernel
- - multiple ne2 support (untested)
- - module support (untested)
-
- Fri Aug 28 00:18:36 CET 1998 (David Weinehall)
- - fixed a few minor typos
- - made the MODULE_PARM conditional (it only works with the v2.1.x kernels)
- - fixed the module support (Now it's working...)
-
- Mon Sep 7 19:01:44 CET 1998 (David Weinehall)
- - added support for Arco Electronics AE/2-card (experimental)
-
- Mon Sep 14 09:53:42 CET 1998 (David Weinehall)

- - Restructuring and rewriting for v2.1.x compliance
-
- Wed Oct 14 17:19:21 CET 1998 (David Weinehall)
- - Added code that unregisters irq and proc-info
- - Version# bump
-
- Mon Nov 16 15:28:23 CET 1998 (Wim Dumon)
- - pass 'dev' as last parameter of request_irq in stead of 'NULL'
-
- Wed Feb 7 21:24:00 CET 2001 (Alfred Arnold)
- - added support for the D-Link DE-320CT
-
- * WARNING
- -------
- This is alpha-test software. It is not guaranteed to work. As a
- matter of fact, I'm quite sure there are *LOTS* of bugs in here. I
- would like to hear from you if you use this driver, even if it works.
- If it doesn't work, be sure to send me a mail with the problems !

-
- This software may be used and distributed according to the terms

-
- Information and Code Sources:
-
- 1) Based upon my other EISA 8390 drivers (lne390, es3210, smc-ultra32)
- 2) The existing myriad of other Linux 8390 drivers by Donald Becker.
- 3) Info for getting IRQ and sh-mem gleaned from the EISA cfg file
-
- The NE3210 is an EISA shared memory NS8390 implementation. Shared
- memory address > 1MB should work with this driver.
-
- Note that the .cfg file (3/11/93, v1.0) has AUI and BNC switched
- around (or perhaps there are some defective/backwards cards ???)
-
- This driver WILL NOT WORK FOR THE NE3200 - it is completely different
- and does not use an 8390 at all.
-
- Updated to EISA probing API 5/2003 by Marc Zyngier.

- A PCMCIA ethernet driver for Asix AX88190-based cards
-
- The Asix AX88190 is a NS8390-derived chipset with a few nasty
- idiosyncracies that make it very inconvenient to support with a
- standard 8390 driver. This driver is based on pcnet_cs, with the
- tweaked 8390 code grafted on the end. Much of what I did was to
- clean up and update a similar driver supplied by Asix, which was
- adapted by William Lee, william@asix.com.tw.

- This is the chip-specific code for many 8390-based ethernet adaptors.
- This is not a complete driver, it must be combined with board-specific
- code such as ne.c, wd.c, 3c503.c, etc.
-
- Seeing how at least eight drivers use this code, (not counting the
- PCMCIA ones either) it is easy to break some card by what seems like
- a simple innocent change. Please contact me or Donald if you think
- you have found something that needs changing. -- PG
-
- Changelog:
-
- Paul Gortmaker : remove set_bit lock, other cleanups.
- Paul Gortmaker : add ei_get_8390_hdr() so we can pass skb's to
- ei_block_input() for eth_io_copy_and_sum().
- Paul Gortmaker : exchange static int ei_pingpong for a #define,
- also add better Tx error handling.
- Paul Gortmaker : rewrite Rx overrun handling as per NS specs.
- Alexey Kuznetsov : use the 8390's six bit hash multicast filter.
- Paul Gortmaker : tweak ANK's above multicast changes a bit.
- Paul Gortmaker : update packet statistics for v2.1.x
- Alan Cox : support arbitrary stupid port mappings on the
- 68K Macintosh. Support >16bit I/O spaces
- Paul Gortmaker : add kmod support for auto-loading of the 8390
- module by all drivers that require it.
- Alan Cox : Spinlocking work, added 'BUG_83C690'
- Paul Gortmaker : Separate out Tx timeout code from Tx path.

- * The 8390 isn't exactly designed to be multithreaded on RX/TX. There is
- * a page register that controls bank and packet buffer access. We guard
- * this with ei_local->page_lock. Nobody should assume or set the page other
- * than zero when the lock is not held. Lock holders must restore page 0
- * before unlocking. Even pure readers must take the lock to protect in
- * page 0.
- *
- * To make life difficult the chip can also be very slow. We therefore can't
- * just use spinlocks. For the longer lockups we disable the irq the device
- * sits on and hold the lock. We must hold the lock because there is a dual
- * processor case other than interrupts (get stats/set multicast list in
- * parallel with each other and transmit).
- *
- * Note: in theory we can just disable the irq on the card _but_ there is
- * a latency on SMP irq delivery. So we can easily go "disable irq" "sync irqs"
- * enter lock, take the queued irq. So we waddle instead of flying.
- *
- * Finally by special arrangement for the purpose of being generally
- * annoying the transmit function is called bh atomic. That places
- * restrictions on the user context callers as disable_irq won't save
- * them.

- A PCMCIA ethernet driver for NS8390-based cards
-
- This driver supports the D-Link DE-650 and Linksys EthernetCard
- cards, the newer D-Link and Linksys combo cards, Accton EN2212
- cards, the RPTI EP400, and the PreMax PE-200 in non-shared-memory
- mode, and the IBM Credit Card Adapter, the NE4100, the Thomas
- Conrad ethernet card, and the Kingston KNE-PCM/x in shared-memory
- mode. It will also handle the Socket EA card in either mode.

-/* smc-mca.c: A SMC Ultra ethernet driver for linux. */
-/*
- Most of this driver, except for ultramca_probe is nearly
- verbatim from smc-ultra.c by Donald Becker. The rest is
- written and copyright 1996 by David Weis, weisd3458@uni.edu
-
- This is a driver for the SMC Ultra and SMC EtherEZ ethercards.
-
- This driver uses the cards in the 8390-compatible, shared memory mode.
- Most of the run-time complexity is handled by the generic code in
- 8390.c.
-
- This driver enables the shared memory only when doing the actual data
- transfers to avoid a bug in early version of the card that corrupted
- data transferred by a AHA1542.
-
- This driver does not support the programmed-I/O data transfer mode of
- the EtherEZ. That support (if available) is smc-ez.c. Nor does it
- use the non-8390-compatible "Altego" mode. (No support currently planned.)
-
- Changelog:
-
- Paul Gortmaker : multiple card support for module users.
- David Weis : Micro Channel-ized it.
- Tom Sightler : Added support for IBM PS/2 Ethernet Adapter/A
- Christopher Turcksin : Changed MCA-probe so that multiple adapters are
- found correctly (Jul 16, 1997)
- Chris Beauregard : Tried to merge the two changes above (Dec 15, 1997)
- Tom Sightler : Fixed minor detection bug caused by above merge
- Tom Sightler : Added support for three more Western Digital
- MCA-adapters
- Tom Sightler : Added support for 2.2.x mca_find_unused_adapter
- Hartmut Schmidt : - Modified parameter detection to handle each
- card differently depending on a switch-list
- - 'card_ver' removed from the adapter list
- - Some minor bug fixes

-/*
- This is a driver for the SMC Ultra and SMC EtherEZ ISA ethercards.
-
- Written 1993-1998 by Donald Becker.
-
- Copyright 1993 United States Government as represented by the
- Director, National Security Agency.

-
- This driver uses the cards in the 8390-compatible mode.
- Most of the run-time complexity is handled by the generic code in
- 8390.c. The code in this file is responsible for
-
- ultra_probe() Detecting and initializing the card.
- ultra_probe1()
- ultra_probe_isapnp()
-
- ultra_open() The card-specific details of starting, stopping
- ultra_reset_8390() and resetting the 8390 NIC core.
- ultra_close()
-
- ultra_block_input() Routines for reading and writing blocks of
- ultra_block_output() packet buffer memory.
- ultra_pio_input()
- ultra_pio_output()
-
- This driver enables the shared memory only when doing the actual data
- transfers to avoid a bug in early version of the card that corrupted
- data transferred by a AHA1542.
-
- This driver now supports the programmed-I/O (PIO) data transfer mode of
- the EtherEZ. It does not use the non-8390-compatible "Altego" mode.
- That support (if available) is in smc-ez.c.
-
- Changelog:
-
- Paul Gortmaker : multiple card support for module users.
- Donald Becker : 4/17/96 PIO support, minor potential problems avoided.
- Donald Becker : 6/6/96 correctly set auto-wrap bit.
- Alexander Sotirov : 1/20/01 Added support for ISAPnP cards
-
- Note about the ISA PnP support:
-
- This driver can not autoprobe for more than one SMC EtherEZ PnP card.
- You have to configure the second card manually through the /proc/isapnp
- interface and then load the module with an explicit io=0x___ option.

-/* smc-ultra32.c: An SMC Ultra32 EISA ethernet driver for linux.
-
-Sources:
-
- This driver is based on (cloned from) the ISA SMC Ultra driver
- written by Donald Becker. Modifications to support the EISA
- version of the card by Paul Gortmaker and Leonard N. Zubkoff.
-
- This software may be used and distributed according to the terms
- of the GNU General Public License, incorporated herein by reference.
-
-Theory of Operation:
-
- The SMC Ultra32C card uses the SMC 83c790 chip which is also
- found on the ISA SMC Ultra cards. It has a shared memory mode of
- operation that makes it similar to the ISA version of the card.
- The main difference is that the EISA card has 32KB of RAM, but
- only an 8KB window into that memory. The EISA card also can be
- set for a bus-mastering mode of operation via the ECU, but that
- is not (and probably will never be) supported by this driver.
- The ECU should be run to enable shared memory and to disable the
- bus-mastering feature for use with linux.
-
- By programming the 8390 to use only 8KB RAM, the modifications
- to the ISA driver can be limited to the probe and initialization
- code. This allows easy integration of EISA support into the ISA
- driver. However, the driver development kit from SMC provided the
- register information for sliding the 8KB window, and hence the 8390
- is programmed to use the full 32KB RAM.
-
- Unfortunately this required code changes outside the probe/init
- routines, and thus we decided to separate the EISA driver from
- the ISA one. In this way, ISA users don't end up with a larger
- driver due to the EISA code, and EISA users don't end up with a
- larger driver due to the ISA EtherEZ PIO code. The driver is
- similar to the 3c503/16 driver, in that the window must be set
- back to the 1st 8KB of space for access to the two 8390 Tx slots.
-
- In testing, using only 8KB RAM (3 Tx / 5 Rx) didn't appear to
- be a limiting factor, since the EISA bus could get packets off
- the card fast enough, but having the use of lots of RAM as Rx
- space is extra insurance if interrupt latencies become excessive.
