-1. Purpose and history
-----------------------
-The tmscsim driver supports PCI SCSI Host Adapters based on the AM53C974
-chip. AM53C974 based SCSI adapters include: 
- Tekram DC390, DC390T
- Dawicontrol 2974
- QLogic Fast! PCI Basic
- some on-board adapters
-(This is most probably not a complete list)
-
-It has originally written by C.L. Huang from the Tekram corp. to support the
-Tekram DC390(T) adapter. This is where the name comes from: tm = Tekram
-scsi = SCSI driver, m = AMD (?) as opposed to w for the DC390W/U/F
-(NCR53c8X5, X=2/7) driver. Yes, there was also a driver for the latter,
-tmscsiw, which supported DC390W/U/F adapters. It's not maintained any more,
-as the ncr53c8xx is perfectly supporting these adapters since some time.
-
-The driver first appeared in April 1996, exclusively supported the DC390 
-and has been enhanced since then in various steps. In May 1998 support for 
-general AM53C974 based adapters and some possibilities to configure it were
-added. The non-DC390 support works by assuming some values for the data
-normally taken from the DC390 EEPROM. See below (chapter 5) for details.
-
-When using the DC390, the configuration is still be done using the DC390
-BIOS setup. The DC390 EEPROM is read and used by the driver, any boot or
-module parameters (chapter 5) are ignored! However, you can change settings
-dynamically, as described in chapter 4. 
-
-For a more detailed description of the driver's history, see the first lines
-of tmscsim.c.
-The numbering scheme isn't consistent. The first versions went from 1.00 to
-1.12, then 1.20a to 1.20t. Finally I decided to use the ncr53c8xx scheme. So
-the next revisions will be 2.0a to 2.0X (stable), 2.1a to 2.1X (experimental),
-2.2a to 2.2X (stable, again) etc. (X = anything between a and z.) If I send
-fixes to people for testing, I create intermediate versions with a digit 
-appended, e.g. 2.0c3.
-
-
-2. Installation
----------------
-If you got any recent kernel with this driver and document included in
-linux/drivers/scsi, you basically have to do nothing special to use this
-driver. Of course you have to choose to compile SCSI support and DC390(T)
-support into your kernel or as module when configuring your kernel for
-compiling.
-NEW: You may as well compile this module outside your kernel, using the
-supplied Makefile.
-
- If you got an old kernel (pre 2.1.127, pre 2.0.37p1) with an old version of
- this driver: Get dc390-21125-20b.diff.gz or dc390-2036p21-20b1.diff.gz from
- my web page and apply the patch. Apply further patches to upgrade to the 
- latest version of the driver.
-
- If you want to do it manually, you should copy the files (dc390.h,
- tmscsim.h, tmscsim.c, scsiiom.c and README.tmscsim) from this directory to
- linux/drivers/scsi. You have to recompile your kernel/module of course.
-
- You should apply the three patches included in dc390-120-kernel.diff
- (Applying them: cd /usr/src; patch -p0 <~/dc390-120-kernel.diff)
- The patches are against 2.1.125, so you might have to manually resolve
- rejections when applying to another kernel version.
-
- The patches will update the kernel startup code to allow boot parameters to
- be passed to the driver, update the Documentation and finally offer you the
- possibility to omit the non-DC390 parts of the driver.
- (By selecting "Omit support for non DC390" you basically disable the
- emulation of a DC390 EEPROM for non DC390 adapters. This saves a few bytes
- of memory.)
-
-If you got a very old kernel without the tmscsim driver (pre 2.0.31)
-I recommend upgrading your kernel. However, if you don't want to, please
-contact me to get the appropriate patches.
-
-
-Upgrading a SCSI driver is always a delicate thing to do. The 2.0 driver has
-proven stable on many systems, but it's still a good idea to take some
-precautions. In an ideal world you would have a full backup of your disks.
-The world isn't ideal and most people don't have full backups (me neither).
-So take at least the following measures:
-* make your kernel remount the FS read-only on detecting an error:
-  tune2fs -e remount-ro /dev/sd??
-* have copies of your SCSI disk's partition tables on some safe location:
-  dd if=/dev/sda of=/mnt/floppy/sda bs=512 count=1
-  or just print it with:
-  fdisk -l | lpr
-* make sure you are able to boot Linux (e.g. from floppy disk using InitRD)
-  if your SCSI disk gets corrupted. You can use 
-  ftp://student.physik.uni-dortmund.de/pub/linux/kernel/bootdisk.gz
-
-One more warning: I used to overclock my PCI bus to 41.67 MHz. My Tekram
-DC390F (Sym53c875) accepted this as well as my Millennium. But the Am53C974
-produced errors and started to corrupt my disks. So don't do that! A 37.50
-MHz PCI bus works for me, though, but I don't recommend using higher clocks
-than the 33.33 MHz being in the PCI spec.

-
-4. Configuration via /proc/scsi/tmscsim/?
------------------------------------------
-First of all look at the output of /proc/scsi/tmscsim/? by typing
- cat /proc/scsi/tmscsim/?
-The "?" should be replaced by the SCSI host number. (The shell might do this
-for you.)
-You will see some info regarding the adapter and, at the end, a listing of
-the attached devices and their settings.
-
-Here's an example:
-garloff@kurt:/home/garloff > cat /proc/scsi/tmscsim/0
-Tekram DC390/AM53C974 PCI SCSI Host Adapter, Driver Version 2.0e7 2000-11-28
-SCSI Host Nr 1, AM53C974 Adapter Nr 0
-IOPortBase 0xb000, IRQ 10
-MaxID 8, MaxLUN 8, AdapterID 6, SelTimeout 250 ms, DelayReset 1 s
-TagMaxNum 16, Status 0x00, ACBFlag 0x00, GlitchEater 24 ns
-Statistics: Cmnds 1470165, Cmnds not sent directly 0, Out of SRB conds 0
-            Lost arbitrations 587,  Sel. connected 0, Connected: No
-Nr of attached devices: 4, Nr of DCBs: 4
-Map of attached LUNs: 01 00 00 03 01 00 00 00
-Idx ID LUN Prty Sync DsCn SndS TagQ NegoPeriod SyncSpeed SyncOffs MaxCmd
-00  00  00  Yes  Yes  Yes  Yes  Yes   100 ns    10.0 M      15      16
-01  03  00  Yes  Yes  Yes  Yes  No    100 ns    10.0 M      15      01
-02  03  01  Yes  Yes  Yes  Yes  No    100 ns    10.0 M      15      01
-03  04  00  Yes  Yes  Yes  Yes  No    100 ns    10.0 M      15      01
-
-Note that the settings MaxID and MaxLUN are not zero- but one-based, which
-means that a setting MaxLUN=4, will result in the support of LUNs 0..3. This
-is somehow inconvenient, but the way the mid-level SCSI code expects it to be.
-
-ACB and DCB are acronyms for Adapter Control Block and Device Control Block.
-These are data structures of the driver containing information about the
-adapter and the connected SCSI devices respectively.
-
-Idx is the device index (just a consecutive number for the driver), ID and
-LUN are the SCSI ID and LUN, Prty means Parity checking, Sync synchronous
-negotiation, DsCn Disconnection, SndS Send Start command on startup (not
-used by the driver) and TagQ Tagged Command Queueing. NegoPeriod and
-SyncSpeed are somehow redundant, because they are reciprocal values 
-(1 / 112 ns = 8.9 MHz). At least in theory. The driver is able to adjust the
-NegoPeriod more accurate (4ns) than the SyncSpeed (1 / 25ns). I don't know
-if certain devices will have problems with this discrepancy. Max. speed is
-10 MHz corresp. to a min. NegoPeriod of 100 ns. 
-(The driver allows slightly higher speeds if the devices (Ultra SCSI) accept
-it, but that's out of adapter spec, on your own risk and unlikely to improve
-performance. You're likely to crash your disks.) 
-SyncOffs is the offset used for synchronous negotiations; max. is 15. 
-The last values are only shown, if Sync is enabled. (NegoPeriod is still
-displayed in brackets to show the values which will be used after enabling
-Sync.)
-MaxCmd ist the number of commands (=tags) which can be processed at the same
-time by the device.
-
-If you want to change a setting, you can do that by writing to
-/proc/scsi/tmscsim/?. Basically you have to imitate the output of driver.
-(Don't use the brackets for NegoPeriod on Sync disabled devices.)
-You don't have to care about capitalisation. The driver will accept space,
-tab, comma, = and : as separators.
-
-There are three kinds of changes: 
-
-(1) Change driver settings: 
-    You type the names of the parameters and the params following it.
-    Example:
-     echo "MaxLUN=8 seltimeout 200" >/proc/scsi/tmscsim/0
-
-    Note that you can only change MaxID, MaxLUN, AdapterID, SelTimeOut,
-    TagMaxNum, ACBFlag, GlitchEater and DelayReset. Don't change ACBFlag
-    unless you want to see what happens, if the driver hangs.
-
-(2) Change device settings: You write a config line to the driver. The Nr
-    must match the ID and LUN given. If you give "-" as parameter, it is
-    ignored and the corresponding setting won't be changed. 
-    You can use "y" or "n" instead of "Yes" and "No" if you want to.
-    You don't need to specify a full line. The driver automatically performs
-    an INQUIRY on the device if necessary to check if it is capable to operate
-    with the given settings (Sync, TagQ).
-    Examples:
-     echo "0 0 0 y y y - y - 10 " >/proc/scsi/tmscsim/0
-     echo "3 5 0 y n y " >/proc/scsi/tmscsim/0
-
-    To give a short explanation of the first example: 
-    The first three numbers, "0 0 0" (Device index 0, SCSI ID 0, SCSI LUN 0),
-    select the device to which the following parameters apply. Note that it
-    would be sufficient to use the index or both SCSI ID and LUN, but I chose
-    to require all three to have a syntax similar to the output.
-    The following "y y y - y" enables Parity checking, enables Synchronous
-    transfers, Disconnection, leaves Send Start (not used) untouched and
-    enables Tagged Command Queueing for the selected device. The "-" skips
-    the Negotiation Period setting but the "10" sets the max sync. speed to
-    10 MHz. It's useless to specify both NegoPeriod and SyncSpeed as
-    discussed above. The values used in this example will result in maximum
-    performance.
-
-(3) Special commands: You can force a SCSI bus reset, an INQUIRY command, the
-    removal or the addition of a device's DCB and a SCSI register dump.
-    This is only used for debugging when you meet problems. The parameter of
-    the INQUIRY and REMOVE commands is the device index as shown by the
-    output of /proc/scsi/tmscsim/? in the device listing in the first column
-    (Idx). ADD takes the SCSI ID and LUN.
-    Examples:
-     echo "reset" >/proc/scsi/tmscsim/0
-     echo "inquiry 1" >/proc/scsi/tmscsim/0
-     echo "remove 2" >/proc/scsi/tmscsim/1
-     echo "add 2 3" >/proc/scsi/tmscsim/?
-     echo "dump" >/proc/scsi/tmscsim/0
-
-    Note that you will meet problems when you REMOVE a device's DCB with the
-    remove command if it contains partitions which are mounted. Only use it
-    after unmounting its partitions, telling the SCSI mid-level code to
-    remove it (scsi remove-single-device) and you really need a few bytes of
-    memory.
-    The ADD command allows you to configure a device before you tell the
-    mid-level code to try detection.
-
-
-I'd suggest reviewing the output of /proc/scsi/tmscsim/? after changing
-settings to see if everything changed as requested.
-
-
-5. Configuration via boot/module parameters
--------------------------------------------
-With the DC390, the driver reads its EEPROM settings and tries to use them.
-But you may want to override the settings prior to being able to change the
-driver configuration via /proc/scsi/tmscsim/?.
-If you do have another AM53C974 based adapter, that's even the only
-possibility to adjust settings before you are able to write to the
-/proc/scsi/tmscsim/? pseudo-file, e.g. if you want to use another 
-adapter ID than 7.  
-(BTW, the log message "DC390: No EEPROM found!" is normal without a DC390.)
-For this purpose, you can pass options to the driver before it is initialised
-by using kernel or module parameters. See lilo(8) or modprobe(1) manual
-pages on how to pass params to the kernel or a module.
-[NOTE: Formerly, it was not possible to override the EEPROM supplied
- settings of the DC390 with cmd line parameters. This has changed since
- 2.0e7]
-
-The syntax of the params is much shorter than the syntax of the /proc/...
-interface. This makes it a little bit more difficult to use. However, long
-parameter lines have the risk to be misinterpreted and the length of kernel
-parameters is limited.
-
-As the support for non-DC390 adapters works by simulating the values of the
-DC390 EEPROM, the settings are given in a DC390 BIOS' way.
-
-Here's the syntax:
-tmscsim=AdaptID,SpdIdx,DevMode,AdaptMode,TaggedCmnds,DelayReset
-
-Each of the parameters is a number, containing the described information:
-
-* AdaptID: The SCSI ID of the host adapter. Must be in the range 0..7
-  Default is 7.
-
-* SpdIdx: The index of the maximum speed as in the DC390 BIOS. The values
-  0..7 mean 10, 8.0, 6.7, 5.7, 5.0, 4.0, 3.1 and 2 MHz resp. Default is
-  0 (10.0 MHz).
-
-* DevMode is a bit mapped value describing the per-device features. It
-  applies to all devices. (Sync, Disc and TagQ will only apply, if the
-  device supports it.) The meaning of the bits (* = default):
-
-   Bit Val(hex) Val(dec)  Meaning
-   *0	 0x01	    1	  Parity check
-   *1	 0x02	    2	  Synchronous Negotiation
-   *2	 0x04	    4	  Disconnection
-   *3	 0x08	    8	  Send Start command on startup. (Not used)
-   *4	 0x10	   16	  Tagged Command Queueing
-
-  As usual, the desired value is obtained by adding the wanted values. If
-  you want to enable all values, e.g., you would use 31(0x1f). Default is 31.
-
-* AdaptMode is a bit mapped value describing the enabled adapter features.
-
-   Bit Val(hex) Val(dec)  Meaning
-   *0	 0x01	    1	  Support more than two drives. (Not used)
-   *1	 0x02	    2	  Use DOS compatible mapping for HDs greater than 1GB.
-   *2	 0x04	    4	  Reset SCSI Bus on startup.
-   *3	 0x08	    8	  Active Negation: Improves SCSI Bus noise immunity.
-    4	 0x10	   16	  Immediate return on BIOS seek command. (Not used)
- (*)5	 0x20	   32	  Check for LUNs >= 1.
-  
-* TaggedCmnds is a number indicating the maximum number of Tagged Commands.
-  It is the binary logarithm - 1 of the actual number. Max is 4 (32).
-   Value  Number of Tagged Commands
-     0		 2
-     1		 4
-     2		 8
-    *3		16
-     4		32
-
-* DelayReset is the time in seconds (minus 0.5s), the adapter waits, after a
-  bus reset. Default is 1 (corresp. to 1.5s).
-
-Example:
- modprobe tmscsim tmscsim=6,2,31
-would set the adapter ID to 6, max. speed to 6.7 MHz, enable all device
-features and leave the adapter features, the number of Tagged Commands
-and the Delay after a reset to the defaults.
-
-As you can see, you don't need to specify all of the six params.
-If you want values to be ignored (i.e. the EEprom settings or the defaults
-will be used), you may pass -2 (not 0!) at the corresponding position.
-
-The defaults (7,0,31,15,3,1) are aggressive to allow good performance. You
-can use tmscsim=7,0,31,63,4,0 for maximum performance, if your SCSI chain
-allows it. If you meet problems, you can use tmscsim=-1 which is a shortcut
-for tmscsim=7,4,9,15,2,10.
-
-
-6. Potential improvements
--------------------------
-Most of the intended work on the driver has been done. Here are a few ideas
-to further improve its usability:
-
-* Cleanly separate per-Target and per-LUN properties (DCB)
-* More intelligent abort() routine
-* Use new_eh code (Linux-2.1+)
-* Have the mid-level (ML) code (and not the driver) handle more of the
-  various conditions.
-* Command queueing in the driver: Eliminate Query list and use ML instead.
-* More user friendly boot/module param syntax
-
-Further investigation on these problems:
-
-* Driver hangs with sync readcdda (xcdroast) (most probably VIA PCI error)
-
-Known problems: 
-Please see http://www.garloff.de/kurt/linux/dc390/problems.html
-
-* Changing the parameters of multi-lun by the tmscsim/? interface will
-  cause problems, cause these settings are mostly per Target and not per LUN
-  and should be updated accordingly. To be fixed for 2.0d24.
-* CDRs (eg Yam CRW4416) not recognized, because some buggy devices don't 
-  recover from a SCSI reset in time. Use a higher delay or don't issue
-  a SCSI bus reset on driver initialization. See problems page.
-  For the CRW4416S, this seems to be solved with firmware 1.0g (reported by 
-  Jean-Yves Barbier).
-* TEAC CD-532S not being recognized. (Works with 1.11).
-* Scanners (eg. Astra UMAX 1220S) don't work: Disable Sync Negotiation.
-  If this does not help, try echo "INQUIRY t" >/proc/scsi/tmscsim/? (t
-  replaced by the dev index of your scanner). You may try to reset your SCSI
-  bus afterwards (echo "RESET" >/proc/scsi/tmscsim/?).
-  The problem seems to be solved as of 2.0d18, thanks to Andreas Rick.
-* If there is a valid partition table, the driver will use it for determining
-  the mapping. If there's none, a reasonable mapping (Symbios-like) will be
-  assumed. Other operating systems may not like this mapping, though
-  it's consistent with the BIOS' behaviour. Old DC390 drivers ignored the
-  partition table and used a H/S = 64/32 or 255/63 translation. So if you
-  want to be compatible to those, use this old mapping when creating
-  partition tables. Even worse, on bootup the DC390 might complain if other
-  mappings are found, so auto rebooting may fail.
-* In some situations, the driver will get stuck in an abort loop. This is a
-  bad interaction between the Mid-Layer of Linux' SCSI code and the driver.
-  Try to disable DsCn, if you meet this problem. Please contact me for
-  further debugging.
-
-
-7. Bug reports, debugging and updates
--------------------------------------
-Whenever you have problems with the driver, you are invited to ask the
-author for help. However, I'd suggest reading the docs and trying to solve
-the problem yourself, first. 
-If you find something, which you believe to be a bug, please report it to me. 
-Please append the output of /proc/scsi/scsi, /proc/scsi/tmscsim/? and
-maybe the DC390 log messages to the report. 
-
-Bug reports should be send to me (Kurt Garloff <dc390@garloff.de>) as well
-as to the linux-scsi list (<linux-scsi@vger.kernel.org>), as sometimes bugs
-are caused by the SCSI mid-level code.
-
-I will ask you for some more details and probably I will also ask you to
-enable some of the DEBUG options in the driver (tmscsim.c:DC390_DEBUGXXX
-defines). The driver will produce some data for the syslog facility then.
-Beware: If your syslog gets written to a SCSI disk connected to your
-AM53C974, the logging might produce log output again, and you might end
-having your box spending most of its time doing the logging.
