tokenring: delete all remaining driver support
This represents the mass deletion of the of the tokenring support. It gets rid of: - the net/tr.c which the drivers depended on - the drivers/net component - the Kbuild infrastructure around it - any tokenring related CONFIG_ settings in any defconfigs - the tokenring headers in the include/linux dir - the firmware associated with the tokenring drivers. - any associated token ring documentation.

22 * Technical Card Details
23 *
24 * All access to data is done with 16/8 bit transfers. The transfer
25 * method really sucks. You can only read or write one location at a time.
26 *
27 * Also, the microcode for the card must be uploaded if the card does not have
28 * the flashrom on board. This is a 28K bloat in the driver when compiled
29 * as a module.
30 *
31 * Rx is very simple, status into a ring of descriptors, dma data transfer,
32 * interrupts to tell us when a packet is received.
33 *
34 * Tx is a little more interesting. Similar scenario, descriptor and dma data
35 * transfers, but we don't have to interrupt the card to tell it another packet
36 * is ready for transmission, we are just doing simple memory writes, not io or mmio
37 * writes. The card can be set up to simply poll on the next
38 * descriptor pointer and when this value is non-zero will automatically download
39 * the next packet. The card then interrupts us when the packet is done.

877 * There are two ways of implementing rx on the 359 NIC, either
878 * interrupt driven or polling. We are going to uses interrupts,
879 * it is the easier way of doing things.
880 *
881 * The Rx works with a ring of Rx descriptors. At initialise time the ring
882 * entries point to the next entry except for the last entry in the ring
883 * which points to 0. The card is programmed with the location of the first
884 * available descriptor and keeps reading the next_ptr until next_ptr is set
885 * to 0. Hopefully with a ring size of 16 the card will never get to read a next_ptr
886 * of 0. As the Rx interrupt is received we copy the frame up to the protocol layers
887 * and then point the end of the ring to our current position and point our current
888 * position to 0, therefore making the current position the last position on the ring.
889 * The last position on the ring therefore loops continually loops around the rx ring.
890 *
891 * rx_ring_tail is the position on the ring to process next. (Think of a snake, the head
892 * expands as the card adds new packets and we go around eating the tail processing the
893 * packets.)
894 *
895 * Undoubtably it could be streamlined and improved upon, but at the moment it works
896 * and the fast path through the routine is fine.
897 *
898 * adv_rx_ring could be inlined to increase performance, but its called a *lot* of times
899 * in xl_rx so would increase the size of the function significantly.

11 Token Ring is IBM's way of communication on a local network; the
12 rest of the world uses Ethernet. To participate on a Token Ring
13 network, you need a special Token ring network card. If you are
14 connected to such a Token Ring network and want to use your Token
15 Ring card under Linux, say Y here and to the driver for your
16 particular card below and read the Token-Ring mini-HOWTO, available
17 from <http://www.tldp.org/docs.html#howto>. Most people can
18 say N here.

1/* ibmtr.c: A shared-memory IBM Token Ring 16/4 driver for linux
2 *
3 * Written 1993 by Mark Swanson and Peter De Schrijver.
4 * This software may be used and distributed according to the terms
5 * of the GNU General Public License, incorporated herein by reference.
6 *
7 * This device driver should work with Any IBM Token Ring Card that does
8 * not use DMA.
9 *
10 * I used Donald Becker's (becker@scyld.com) device driver work
11 * as a base for most of my initial work.
12 *
13 * Changes by Peter De Schrijver
14 * (Peter.Deschrijver@linux.cc.kuleuven.ac.be) :
15 *
16 * + changed name to ibmtr.c in anticipation of other tr boards.
17 * + changed reset code and adapter open code.
18 * + added SAP open code.
19 * + a first attempt to write interrupt, transmit and receive routines.
20 *
21 * Changes by David W. Morris (dwm@shell.portal.com) :
22 * 941003 dwm: - Restructure tok_probe for multiple adapters, devices.
23 * + Add comments, misc reorg for clarity.
24 * + Flatten interrupt handler levels.
25 *
26 * Changes by Farzad Farid (farzy@zen.via.ecp.fr)
27 * and Pascal Andre (andre@chimay.via.ecp.fr) (March 9 1995) :
28 * + multi ring support clean up.
29 * + RFC1042 compliance enhanced.
30 *
31 * Changes by Pascal Andre (andre@chimay.via.ecp.fr) (September 7 1995) :
32 * + bug correction in tr_tx
33 * + removed redundant information display
34 * + some code reworking
35 *
36 * Changes by Michel Lespinasse (walken@via.ecp.fr),
37 * Yann Doussot (doussot@via.ecp.fr) and Pascal Andre (andre@via.ecp.fr)
38 * (February 18, 1996) :
39 * + modified shared memory and mmio access port the driver to
40 * alpha platform (structure access -> readb/writeb)
41 *
42 * Changes by Steve Kipisz (bungy@ibm.net or kipisz@vnet.ibm.com)
43 * (January 18 1996):
44 * + swapped WWOR and WWCR in ibmtr.h
45 * + moved some init code from tok_probe into trdev_init. The
46 * PCMCIA code can call trdev_init to complete initializing
47 * the driver.
48 * + added -DPCMCIA to support PCMCIA
49 * + detecting PCMCIA Card Removal in interrupt handler. If
50 * ISRP is FF, then a PCMCIA card has been removed
51 * 10/2000 Burt needed a new method to avoid crashing the OS
52 *
53 * Changes by Paul Norton (pnorton@cts.com) :
54 * + restructured the READ.LOG logic to prevent the transmit SRB
55 * from being rudely overwritten before the transmit cycle is
56 * complete. (August 15 1996)
57 * + completed multiple adapter support. (November 20 1996)
58 * + implemented csum_partial_copy in tr_rx and increased receive
59 * buffer size and count. Minor fixes. (March 15, 1997)
60 *
61 * Changes by Christopher Turcksin <wabbit@rtfc.demon.co.uk>
62 * + Now compiles ok as a module again.
63 *
64 * Changes by Paul Norton (pnorton@ieee.org) :
65 * + moved the header manipulation code in tr_tx and tr_rx to
66 * net/802/tr.c. (July 12 1997)
67 * + add retry and timeout on open if cable disconnected. (May 5 1998)
68 * + lifted 2000 byte mtu limit. now depends on shared-RAM size.
69 * May 25 1998)
70 * + can't allocate 2k recv buff at 8k shared-RAM. (20 October 1998)
71 *
72 * Changes by Joel Sloan (jjs@c-me.com) :
73 * + disable verbose debug messages by default - to enable verbose
74 * debugging, edit the IBMTR_DEBUG_MESSAGES define below
75 *
76 * Changes by Mike Phillips <phillim@amtrak.com> :
77 * + Added extra #ifdef's to work with new PCMCIA Token Ring Code.
78 * The PCMCIA code now just sets up the card so it can be recognized
79 * by ibmtr_probe. Also checks allocated memory vs. on-board memory
80 * for correct figure to use.
81 *
82 * Changes by Tim Hockin (thockin@isunix.it.ilstu.edu) :
83 * + added spinlocks for SMP sanity (10 March 1999)
84 *
85 * Changes by Jochen Friedrich to enable RFC1469 Option 2 multicasting
86 * i.e. using functional address C0 00 00 04 00 00 to transmit and
87 * receive multicast packets.
88 *
89 * Changes by Mike Sullivan (based on original sram patch by Dave Grothe
90 * to support windowing into on adapter shared ram.
91 * i.e. Use LANAID to setup a PnP configuration with 16K RAM. Paging
92 * will shift this 16K window over the entire available shared RAM.
93 *
94 * Changes by Peter De Schrijver (p2@mind.be) :
95 * + fixed a problem with PCMCIA card removal
96 *
97 * Change by Mike Sullivan et al.:
98 * + added turbo card support. No need to use lanaid to configure
99 * the adapter into isa compatibility mode.
100 *
101 * Changes by Burt Silverman to allow the computer to behave nicely when
102 * a cable is pulled or not in place, or a PCMCIA card is removed hot.

3 A PCMCIA token-ring driver for IBM-based cards
4
5 This driver supports the IBM PCMCIA Token-Ring Card.
6 Written by Steve Kipisz, kipisz@vnet.ibm.com or
7 bungy@ibm.net
8
9 Written 1995,1996.
10
11 This code is based on pcnet_cs.c from David Hinds.
12
13 V2.2.0 February 1999 - Mike Phillips phillim@amtrak.com
14
15 Linux V2.2.x presented significant changes to the underlying
16 ibmtr.c code. Mainly the code became a lot more organized and
17 modular.
18
19 This caused the old PCMCIA Token Ring driver to give up and go
20 home early. Instead of just patching the old code to make it
21 work, the PCMCIA code has been streamlined, updated and possibly
22 improved.
23
24 This code now only contains code required for the Card Services.
25 All we do here is set the card up enough so that the real ibmtr.c
26 driver can find it and work with it properly.
27
28 i.e. We set up the io port, irq, mmio memory and shared ram
29 memory. This enables ibmtr_probe in ibmtr.c to find the card and
30 configure it as though it was a normal ISA and/or PnP card.
31
32 CHANGES
33
34 v2.2.5 April 1999 Mike Phillips (phillim@amtrak.com)
35 Obscure bug fix, required changed to ibmtr.c not ibmtr_cs.c
36
37 v2.2.7 May 1999 Mike Phillips (phillim@amtrak.com)
38 Updated to version 2.2.7 to match the first version of the kernel
39 that the modification to ibmtr.c were incorporated into.
40
41 v2.2.17 July 2000 Burt Silverman (burts@us.ibm.com)
42 Address translation feature of PCMCIA controller is usable so
43 memory windows can be placed in High memory (meaning above
44 0xFFFFF.)

56 *
57 * 12/10/99 - Alpha Release 0.1.0
58 * First release to the public
59 * 03/03/00 - Merged to kernel, indented -kr -i8 -bri0, fixed some missing
60 * malloc free checks, reviewed code. <alan@redhat.com>
61 * 03/13/00 - Added spinlocks for smp
62 * 03/08/01 - Added support for module_init() and module_exit()
63 * 08/15/01 - Added ioctl() functionality for debugging, changed netif_*_queue
64 * calls and other incorrectness - Kent Yoder <yoder1@us.ibm.com>
65 * 11/05/01 - Restructured the interrupt function, added delays, reduced the
66 * the number of TX descriptors to 1, which together can prevent
67 * the card from locking up the box - <yoder1@us.ibm.com>
68 * 09/27/02 - New PCI interface + bug fix. - <yoder1@us.ibm.com>
69 * 11/13/02 - Removed free_irq calls which could cause a hang, added
70 * netif_carrier_{on|off} - <yoder1@us.ibm.com>
71 *
72 * To Do:
73 *
74 *
75 * If Problems do Occur
76 * Most problems can be rectified by either closing and opening the interface
77 * (ifconfig down and up) or rmmod and insmod'ing the driver (a bit difficult
78 * if compiled into the kernel).

371 * Handle interrupts generated by the card

373 * The MicroChannel Madge cards need slightly more handling
374 * after an interrupt than other TMS380 cards do.
375 *
376 * First we must make sure it was this card that generated the
377 * interrupt (since interrupt sharing is allowed). Then,
378 * because we're using level-triggered interrupts (as is
379 * standard on MCA), we must toggle the interrupt line
380 * on the card in order to claim and acknowledge the interrupt.
381 * Once that is done, the interrupt should be handlable in
382 * the normal tms380tr_interrupt() routine.
383 *
384 * There's two ways we can check to see if the interrupt is ours,
385 * both with their own disadvantages...
386 *
387 * 1) Read in the SIFSTS register from the TMS controller. This
388 * is guaranteed to be accurate, however, there's a fairly
389 * large performance penalty for doing so: the Madge chips
390 * must request the register from the Eagle, the Eagle must
391 * read them from its internal bus, and then take the route
392 * back out again, for a 16bit read.
393 *
394 * 2) Use the MC_CONTROL_REG0_SINTR bit from the Madge ASICs.
395 * The major disadvantage here is that the accuracy of the
396 * bit is in question. However, it cuts out the extra read
397 * cycles it takes to read the Eagle's SIF, as its only an
398 * 8bit read, and theoretically the Madge bit is directly
399 * connected to the interrupt latch coming out of the Eagle
400 * hardware (that statement is not verified).
401 *
402 * I can't determine which of these methods has the best win. For now,
403 * we make a compromise. Use the Madge way for the first interrupt,
404 * which should be the fast-path, and then once we hit the first
405 * interrupt, keep on trying using the SIF method until we've
406 * exhausted all contiguous interrupts.

2 * olympic.c (c) 1999 Peter De Schrijver All Rights Reserved
3 * 1999/2000 Mike Phillips (mikep@linuxtr.net)
4 *
5 * Linux driver for IBM PCI tokenring cards based on the Pit/Pit-Phy/Olympic
6 * chipset.
7 *
8 * Base Driver Skeleton:
9 * Written 1993-94 by Donald Becker.
10 *
11 * Copyright 1993 United States Government as represented by the
12 * Director, National Security Agency.
13 *
14 * Thanks to Erik De Cock, Adrian Bridgett and Frank Fiene for their
15 * assistance and perserverance with the testing of this driver.
16 *
17 * This software may be used and distributed according to the terms
18 * of the GNU General Public License, incorporated herein by reference.
19 *
20 * 4/27/99 - Alpha Release 0.1.0
21 * First release to the public
22 *
23 * 6/8/99 - Official Release 0.2.0
24 * Merged into the kernel code
25 * 8/18/99 - Updated driver for 2.3.13 kernel to use new pci
26 * resource. Driver also reports the card name returned by
27 * the pci resource.
28 * 1/11/00 - Added spinlocks for smp
29 * 2/23/00 - Updated to dev_kfree_irq
30 * 3/10/00 - Fixed FDX enable which triggered other bugs also
31 * squashed.
32 * 5/20/00 - Changes to handle Olympic on LinuxPPC. Endian changes.
33 * The odd thing about the changes is that the fix for
34 * endian issues with the big-endian data in the arb, asb...
35 * was to always swab() the bytes, no matter what CPU.
36 * That's because the read[wl]() functions always swap the
37 * bytes on the way in on PPC.
38 * Fixing the hardware descriptors was another matter,
39 * because they weren't going through read[wl](), there all
40 * the results had to be in memory in le32 values. kdaaker
41 *
42 * 12/23/00 - Added minimal Cardbus support (Thanks Donald).
43 *
44 * 03/09/01 - Add new pci api, dev_base_lock, general clean up.
45 *
46 * 03/27/01 - Add new dma pci (Thanks to Kyle Lucke) and alloc_trdev
47 * Change proc_fs behaviour, now one entry per adapter.
48 *
49 * 04/09/01 - Couple of bug fixes to the dma unmaps and ejecting the
50 * adapter when live does not take the system down with it.
51 *
52 * 06/02/01 - Clean up, copy skb for small packets
53 *
54 * 06/22/01 - Add EISR error handling routines
55 *
56 * 07/19/01 - Improve bad LAA reporting, strip out freemem
57 * into a separate function, its called from 3
58 * different places now.
59 * 02/09/02 - Replaced sleep_on.
60 * 03/01/02 - Replace access to several registers from 32 bit to
61 * 16 bit. Fixes alignment errors on PPC 64 bit machines.
62 * Thanks to Al Trautman for this one.
63 * 03/10/02 - Fix BUG in arb_cmd. Bug was there all along but was
64 * silently ignored until the error checking code
65 * went into version 1.0.0
66 * 06/04/02 - Add correct start up sequence for the cardbus adapters.
67 * Required for strict compliance with pci power mgmt specs.
68 * To Do:
69 *
70 * Wake on lan
71 *
72 * If Problems do Occur
73 * Most problems can be rectified by either closing and opening the interface
74 * (ifconfig down and up) or rmmod and insmod'ing the driver (a bit difficult
75 * if compiled into the kernel).

4 * Based on tmspci written 1999 by Adam Fritzler
5 *
6 * Written 2000 by Jochen Friedrich
7 * Dedicated to my girlfriend Steffi Bopp
8 *
9 * This software may be used and distributed according to the terms
10 * of the GNU General Public License, incorporated herein by reference.
11 *
12 * This driver module supports the following cards:
13 * - SysKonnect TR4/16(+) ISA (SK-4190)

16 * AF Adam Fritzler
17 * JF Jochen Friedrich jochen@scram.de
18 *
19 * Modification History:
20 * 14-Jan-01 JF Created
21 * 28-Oct-02 JF Fixed probe of card for static compilation.
22 * Fixed module init to not make hotplug go wild.
23 * 09-Nov-02 JF Fixed early bail out on out of memory
24 * situations if multiple cards are found.
25 * Cleaned up some unnecessary console SPAM.
26 * 09-Dec-02 JF Fixed module reference counting.
27 * 02-Jan-03 JF Renamed to skisa.c

2 * tms380tr.c: A network driver library for Texas Instruments TMS380-based
3 * Token Ring Adapters.
4 *
5 * Originally sktr.c: Written 1997 by Christoph Goos
6 *
7 * A fine result of the Linux Systems Network Architecture Project.
8 * http://www.vanheusden.com/sna/
9 *
10 * This software may be used and distributed according to the terms
11 * of the GNU General Public License, incorporated herein by reference.
12 *
13 * The following modules are currently available for card support:
14 * - tmspci (Generic PCI card support)
15 * - abyss (Madge PCI support)
16 * - tmsisa (SysKonnect TR4/16 ISA)
17 *
18 * Sources:
19 * - The hardware related parts of this driver are take from
20 * the SysKonnect Token Ring driver for Windows NT.
21 * - I used the IBM Token Ring driver 'ibmtr.c' as a base for this
22 * driver, as well as the 'skeleton.c' driver by Donald Becker.
23 * - Also various other drivers in the linux source tree were taken
24 * as samples for some tasks.
25 * - TI TMS380 Second-Generation Token Ring User's Guide
26 * - TI datasheets for respective chips
27 * - David Hein at Texas Instruments
28 * - Various Madge employees

31 * JS Jay Schulist jschlst@samba.org
32 * CG Christoph Goos cgoos@syskonnect.de
33 * AF Adam Fritzler
34 * MLP Mike Phillips phillim@amtrak.com
35 * JF Jochen Friedrich jochen@scram.de
36 *
37 * Modification History:
38 * 29-Aug-97 CG Created
39 * 04-Apr-98 CG Fixed problems caused by tok_timer_check
40 * 10-Apr-98 CG Fixed lockups at cable disconnection
41 * 27-May-98 JS Formated to Linux Kernel Format
42 * 31-May-98 JS Hacked in PCI support
43 * 16-Jun-98 JS Modulized for multiple cards with one driver
44 * Sep-99 AF Renamed to tms380tr (supports more than SK's)
45 * 23-Sep-99 AF Added Compaq and Thomas-Conrad PCI support
46 * Fixed a bug causing double copies on PCI
47 * Fixed for new multicast stuff (2.2/2.3)
48 * 25-Sep-99 AF Uped TPL_NUM from 3 to 9
49 * Removed extraneous 'No free TPL'
50 * 22-Dec-99 AF Added Madge PCI Mk2 support and generalized
51 * parts of the initilization procedure.
52 * 30-Dec-99 AF Turned tms380tr into a library ala 8390.
53 * Madge support is provided in the abyss module
54 * Generic PCI support is in the tmspci module.
55 * 30-Nov-00 JF Updated PCI code to support IO MMU via
56 * pci_map_static(). Alpha uses this MMU for ISA
57 * as well.
58 * 14-Jan-01 JF Fix DMA on ifdown/ifup sequences. Some
59 * cleanup.
60 * 13-Jan-02 JF Add spinlock to fix race condition.
61 * 09-Nov-02 JF Fixed printks to not SPAM the console during
62 * normal operation.
63 * 30-Dec-02 JF Removed incorrect __init from
64 * tms380tr_init_card.
65 * 22-Jul-05 JF Converted to dma-mapping.
66 *
67 * To do:
68 * 1. Multi/Broadcast packet handling (this may have fixed itself)
69 * 2. Write a sktrisa module that includes the old ISA support (done)
70 * 3. Allow modules to load their own microcode
71 * 4. Speed up the BUD process -- freezing the kernel for 3+sec is
72 * quite unacceptable.
73 * 5. Still a few remaining stalls when the cable is unplugged.
