The 1650 and 1670 have a - 25-pin external connector, whereas the 1660 and 1680 have a SCSI-2 50-pin - high-density external connector. The 1670 and 1680 have floppy disk - controllers built in. The TMC-3260 is a PCI bus card. - - Future Domain's older boards are based on the TMC-1800 chip, and this - driver was originally written for a TMC-1680 board with the TMC-1800 chip. - More recently, boards are being produced with the TMC-18C50 and TMC-18C30 - chips. The latest and greatest board may not work with this driver. If - you have to patch this driver so that it will recognize your board's BIOS - signature, then the driver may fail to function after the board is - detected. - - Please note that the drive ordering that Future Domain implemented in BIOS - versions 3.4 and 3.5 is the opposite of the order (currently) used by the - rest of the SCSI industry. If you have BIOS version 3.4 or 3.5, and have - more than one drive, then the drive ordering will be the reverse of that - which you see under DOS. For example, under DOS SCSI ID 0 will be D: and - SCSI ID 1 will be C: (the boot device). Under Linux, SCSI ID 0 will be - /dev/sda and SCSI ID 1 will be /dev/sdb. The Linux ordering is consistent - with that provided by all the other SCSI drivers for Linux. If you want - this changed, you will probably have to patch the higher level SCSI code. - If you do so, please send me patches that are protected by #ifdefs. - - If you have a TMC-8xx or TMC-9xx board, then this is not the driver for - your board. Please refer to the Seagate driver for more information and - possible support. - - - - HISTORY: - - Linux Driver Driver - Version Version Date Support/Notes - - 0.0 3 May 1992 V2.0 BIOS; 1800 chip - 0.97 1.9 28 Jul 1992 - 0.98.6 3.1 27 Nov 1992 - 0.99 3.2 9 Dec 1992 - - 0.99.3 3.3 10 Jan 1993 V3.0 BIOS - 0.99.5 3.5 18 Feb 1993 - 0.99.10 3.6 15 May 1993 V3.2 BIOS; 18C50 chip - 0.99.11 3.17 3 Jul 1993 (now under RCS) - 0.99.12 3.18 13 Aug 1993 - 0.99.14 5.6 31 Oct 1993 (reselection code removed) - - 0.99.15 5.9 23 Jan 1994 V3.4 BIOS (preliminary) - 1.0.8/1.1.1 5.15 1 Apr 1994 V3.4 BIOS; 18C30 chip (preliminary) - 1.0.9/1.1.3 5.16 7 Apr 1994 V3.4 BIOS; 18C30 chip - 1.1.38 5.18 30 Jul 1994 36C70 chip (PCI version of 18C30) - 1.1.62 5.20 2 Nov 1994 V3.5 BIOS - 1.1.73 5.22 7 Dec 1994 Quantum ISA-200S board; V2.0 BIOS - - 1.1.82 5.26 14 Jan 1995 V3.5 BIOS; TMC-1610M/MER/MEX board - 1.2.10 5.28 5 Jun 1995 Quantum ISA-250MG board; V2.0, V2.01 BIOS - 1.3.4 5.31 23 Jun 1995 PCI BIOS-32 detection (preliminary) - 1.3.7 5.33 4 Jul 1995 PCI BIOS-32 detection - 1.3.28 5.36 17 Sep 1995 V3.61 BIOS; LILO command-line support - 1.3.34 5.39 12 Oct 1995 V3.60 BIOS; /proc - 1.3.72 5.39 8 Feb 1996 Adaptec AHA-2920 board - 1.3.85 5.41 4 Apr 1996 - 2.0.12 5.44 8 Aug 1996 Use ID 7 for all PCI cards - 2.1.1 5.45 2 Oct 1996 Update ROM accesses for 2.1.x - 2.1.97 5.46 23 Apr 1998 Rewritten PCI detection routines [mj] - 2.1.11x 5.47 9 Aug 1998 Touched for 8 SCSI disk majors support - 5.48 18 Nov 1998 BIOS no longer needed for PCI detection - 2.2.0 5.50 28 Dec 1998 Support insmod parameters - - - REFERENCES USED: - - "TMC-1800 SCSI Chip Specification (FDC-1800T)", Future Domain Corporation, - 1990. - - "Technical Reference Manual: 18C50 SCSI Host Adapter Chip", Future Domain - Corporation, January 1992. - - "LXT SCSI Products: Specifications and OEM Technical Manual (Revision - B/September 1991)", Maxtor Corporation, 1991. - - "7213S product Manual (Revision P3)", Maxtor Corporation, 1992. - - "Draft Proposed American National Standard: Small Computer System - Interface - 2 (SCSI-2)", Global Engineering Documents.

Maxtor telephone technical support is - great! - - The Future Domain manuals were $25 and $35. They document the chip, not - the TMC-16x0 boards, so some information I had to guess at. In 1992, - Future Domain sold DOS BIOS source for $250 and the UN*X driver source was - $750, but these required a non-disclosure agreement, so even if I could - have afforded them, they would *not* have been useful for writing this - publicly distributable driver. Future Domain technical support has - provided some information on the phone and have sent a few useful FAXs. - They have been much more helpful since they started to recognize that the - word "Linux" refers to an operating system :-). - - - - ALPHA TESTERS: - - There are many other alpha testers that come and go as the driver - develops. The people listed here were most helpful in times of greatest - need (mostly early on -- I've probably left out a few worthy people in - more recent times): - - Todd Carrico (todd@xxxxxxxxxxxxxx), Dan Poirier (poirier@xxxxxxxxxx ), Ken - Corey (kenc@xxxxxxxxxxxxxxx), C. de Bruin (bruin@bruin@xxxxxxxxxx), Sakari - Aaltonen (sakaria@xxxxxxxxxxxxxx), John Rice (rice@xxxxxxxxxxxxxxxx), Brad - Yearwood (brad@xxxxxxxxxxxx), and Ray Toy (toy@xxxxxxxxxxxxxxx). - - Special thanks to Tien-Wan Yang (twyang@xxxxxxxxx), who graciously lent me - his 18C50-based card for debugging. He is the sole reason that this - driver works with the 18C50 chip. - - Thanks to Dave Newman (dnewman@xxxxxxx) for providing initial patches for - the version 3.4 BIOS. - - Thanks to James T. McKinley (mckinley@xxxxxxxxxxxxxxxx) for providing - patches that support the TMC-3260, a PCI bus card with the 36C70 chip. - The 36C70 chip appears to be "completely compatible" with the 18C30 chip. - - Thanks to Eric Kasten (tigger@xxxxxxxxxxxxxxxxxxxxx) for providing the - patch for the version 3.5 BIOS. - - Thanks for Stephen Henson (shenson@xxxxxxxxxxxxxxx) for providing the - patch for the Quantum ISA-200S SCSI adapter. - - Thanks to Adam Bowen for the signature to the 1610M/MER/MEX scsi cards, to - Martin Andrews (andrewm@xxxxxxxxxxxxxxxxxx) for the signature to some - random TMC-1680 repackaged by IBM; and to Mintak Ng (mintak@xxxxxxxxx) for - the version 3.61 BIOS signature. - - Thanks for Mark Singer (elf@xxxxxxxxxx) and Richard Simpson - (rsimpson@xxxxxxxxxxxxxxxxxxxx) for more Quantum signatures and detective - work on the Quantum RAM layout. - - Special thanks to James T. McKinley (mckinley@xxxxxxxxxxxxxxxx) for - providing patches for proper PCI BIOS32-mediated detection of the TMC-3260 - card (a PCI bus card with the 36C70 chip). Please send James PCI-related - bug reports. - - Thanks to Tom Cavin (tec@xxxxxxxx) for preliminary command-line option - patches. - - New PCI detection code written by Martin Mares <mj@xxxxxxxxxxxxxxxxxxxxxxxx> - - Insmod parameter code based on patches from Daniel Graham - <graham@xxxxxxxxxxxxxxxxxxx>. - - All of the alpha testers deserve much thanks. - - - - NOTES ON USER DEFINABLE OPTIONS: - - DEBUG: This turns on the printing of various debug information. - - ENABLE_PARITY: This turns on SCSI parity checking. With the current - driver, all attached devices must support SCSI parity. If none of your - devices support parity, then you can probably get the driver to work by - turning this option off. I have no way of testing this, however, and it - would appear that no one ever uses this option. - - FIFO_COUNT: The host adapter has an 8K cache (host adapters based on the - 18C30 chip have a 2k cache). When this many 512 byte blocks are filled by - the SCSI device, an interrupt will be raised. Therefore, this could be as - low as 0, or as high as 16. Note, however, that values which are too high - or too low seem to prevent any interrupts from occurring, and thereby lock - up the machine. I have found that 2 is a good number, but throughput may - be increased by changing this value to values which are close to 2. - Please let me know if you try any different values. - - RESELECTION: This is no longer an option, since I gave up trying to - implement it in version 4.x of this driver. It did not improve - performance at all and made the driver unstable (because I never found one - of the two race conditions which were introduced by the multiple - outstanding command code). The instability seems a very high price to pay - just so that you don't have to wait for the tape to rewind. If you want - this feature implemented, send me patches. I'll be happy to send a copy - of my (broken) driver to anyone who would like to see a copy. - - **************************************************************************/ - -#include <linux/module.h> -#include <linux/init.h> -#include <linux/interrupt.h> -#include <linux/blkdev.h> -#include <linux/spinlock.h> -#include <linux/errno.h> -#include <linux/string.h> -#include <linux/ioport.h> -#include <linux/proc_fs.h> -#include <linux/pci.h> -#include <linux/stat.h> -#include <linux/delay.h> -#include <linux/io.h> -#include <linux/slab.h> -#include <scsi/scsicam.h> - - -#include <scsi/scsi.h> -#include <scsi/scsi_cmnd.h> -#include <scsi/scsi_device.h> -#include <scsi/scsi_host.h> -#include <scsi/scsi_ioctl.h> -#include "fdomain.h" - -#ifndef PCMCIA -MODULE_AUTHOR("Rickard E.
