- *      u14-34f.c - Low-level driver for UltraStor 14F/34F SCSI host adapters.
- *
- *      03 Jun 2003 Rev. 8.10 for linux-2.5.70
- *        + Update for new IRQ API.
- *        + Use "goto" when appropriate.
- *        + Drop u14-34f.h.
- *        + Update for new module_param API.
- *        + Module parameters  can now be specified only in the
- *          same format as the kernel boot options.
- *
- *             boot option    old module param 
- *             -----------    ------------------
- *             addr,...       io_port=addr,...
- *             lc:[y|n]       linked_comm=[1|0]

- *             of:[y|n]       have_old_firmware=[1|0]
- *
- *          A valid example using the new parameter format is:
- *          modprobe u14-34f "u14-34f=0x340,0x330,lc:y,tm:0,mq:4"
- *
- *          which is equivalent to the old format:

- *                        max_queue_depth=4
- *
- *          With actual module code, u14-34f and u14_34f are equivalent
- *          as module parameter names.
- *
- *      12 Feb 2003 Rev. 8.04 for linux 2.5.60
- *        + Release irq before calling scsi_register.

- *      28 Oct 2002 Rev. 8.00 for linux 2.5.44-ac4
- *        + Use new tcq and adjust_queue_depth api.
- *        + New command line option (tm:[0-2]) to choose the type of tags:
- *          0 -> disable tagging ; 1 -> simple tags  ; 2 -> ordered tags.
- *          Default is tm:0 (tagged commands disabled).
- *          For compatibility the "tc:" option is an alias of the "tm:"
- *          option; tc:n is equivalent to tm:0 and tc:y is equivalent to
- *          tm:1.
- *
- *      10 Oct 2002 Rev. 7.70 for linux 2.5.42

- *        + Updated to the new __setup interface for boot command line options.
- *        + When loaded as a module, accepts the new parameter boot_options
- *          which value is a string with the same format of the kernel boot
- *          command line options. A valid example is:

- *
- *      13 May 1998 Rev. 4.30 for linux 2.0.33 and 2.1.101
- *          The driver is now fully SMP safe, including the
- *          abort and reset routines.
- *          Added command line options (eh:[y|n]) to choose between
- *          new_eh_code and the old scsi code.
- *          If linux version >= 2.1.101 the default is eh:y, while the eh
- *          option is ignored for previous releases and the old scsi code

- *          Reworked interrupt handler.
- *
- *      11 Apr 1998 rev. 4.05 for linux 2.0.33 and 2.1.95
- *          Major reliability improvement: when a batch with overlapping
- *          requests is detected, requests are queued one at a time
- *          eliminating any possible board or drive reordering.
- *
- *      10 Apr 1998 rev. 4.04 for linux 2.0.33 and 2.1.95

- *
- *       9 Apr 1998 rev. 4.03 for linux 2.0.33 and 2.1.94
- *          Performance improvement: when sequential i/o is detected,
- *          always use direct sort instead of reverse sort.
- *
- *       4 Apr 1998 rev. 4.02 for linux 2.0.33 and 2.1.92
- *          io_port is now unsigned long.
- *
- *      17 Mar 1998 rev. 4.01 for linux 2.0.33 and 2.1.88
- *          Use new scsi error handling code (if linux version >= 2.1.88).
- *          Use new interrupt code.
- *
- *      12 Sep 1997 rev. 3.11 for linux 2.0.30 and 2.1.55
- *          Use of udelay inside the wait loops to avoid timeout
- *          problems with fast cpus.
- *          Removed check about useless calls to the interrupt service
- *          routine (reported on SMP systems only).
- *          At initialization time "sorted/unsorted" is displayed instead
- *          of "linked/unlinked" to reinforce the fact that "linking" is
- *          nothing but "elevator sorting" in the actual implementation.
- *
- *      17 May 1997 rev. 3.10 for linux 2.0.30 and 2.1.38
- *          Use of serial_number_at_timeout in abort and reset processing.
- *          Use of the __initfunc and __initdata macro in setup code.
- *          Minor cleanups in the list_statistics code.
- *
- *      24 Feb 1997 rev. 3.00 for linux 2.0.29 and 2.1.26
- *          When loading as a module, parameter passing is now supported
- *          both in 2.0 and in 2.1 style.
- *          Fixed data transfer direction for some SCSI opcodes.
- *          Immediate acknowledge to request sense commands.
- *          Linked commands to each disk device are now reordered by elevator
- *          sorting. Rare cases in which reordering of write requests could
- *          cause wrong results are managed.
- *
- *      18 Jan 1997 rev. 2.60 for linux 2.1.21 and 2.0.28
- *          Added command line options to enable/disable linked commands
- *          (lc:[y|n]), old firmware support (of:[y|n]) and to set the max
- *          queue depth (mq:xx). Default is "u14-34f=lc:n,of:n,mq:8".
- *          Improved command linking.
- *
- *       8 Jan 1997 rev. 2.50 for linux 2.1.20 and 2.0.27
- *          Added linked command support.
- *
- *       3 Dec 1996 rev. 2.40 for linux 2.1.14 and 2.0.27

- *          The list of i/o ports to be probed can be overwritten by the
- *          "u14-34f=port0,port1,...." boot command line option.
- *          Scatter/gather lists are now allocated by a number of kmalloc
- *          calls, in order to avoid the previous size limit of 64Kb.

- *          Multiple U14F and/or U34F host adapters are supported.

-/*
- *  The UltraStor 14F, 24F, and 34F are a family of intelligent, high
- *  performance SCSI-2 host adapters.
- *  Here is the scoop on the various models:
- *
- *  14F - ISA first-party DMA HA with floppy support and WD1003 emulation.
- *  24F - EISA Bus Master HA with floppy support and WD1003 emulation.
- *  34F - VESA Local-Bus Bus Master HA (no WD1003 emulation).
- *
- *  This code has been tested with up to two U14F boards, using both
- *  firmware 28004-005/38004-004 (BIOS rev. 2.00) and the latest firmware
- *  28004-006/38004-005 (BIOS rev. 2.01).
- *
- *  The latest firmware is required in order to get reliable operations when
- *  clustering is enabled. ENABLE_CLUSTERING provides a performance increase
- *  up to 50% on sequential access.
- *
- *  Since the struct scsi_host_template structure is shared among all 14F and 34F,
- *  the last setting of use_clustering is in effect for all of these boards.
- *
- *  Here a sample configuration using two U14F boards:
- *
- U14F0: ISA 0x330, BIOS 0xc8000, IRQ 11, DMA 5, SG 32, MB 16, of:n, lc:y, mq:8.
- U14F1: ISA 0x340, BIOS 0x00000, IRQ 10, DMA 6, SG 32, MB 16, of:n, lc:y, mq:8.
- *
- *  The boot controller must have its BIOS enabled, while other boards can
- *  have their BIOS disabled, or enabled to an higher address.
- *  Boards are named Ux4F0, Ux4F1..., according to the port address order in
- *  the io_port[] array.
- *
- *  The following facts are based on real testing results (not on
- *  documentation) on the above U14F board.
- *
- *  - The U14F board should be jumpered for bus on time less or equal to 7
- *    microseconds, while the default is 11 microseconds. This is order to
- *    get acceptable performance while using floppy drive and hard disk
- *    together. The jumpering for 7 microseconds is: JP13 pin 15-16,
- *    JP14 pin 7-8 and pin 9-10.
- *    The reduction has a little impact on scsi performance.
- *
- *  - If scsi bus length exceeds 3m., the scsi bus speed needs to be reduced
- *    from 10Mhz to 5Mhz (do this by inserting a jumper on JP13 pin 7-8).
- *
- *  - If U14F on board firmware is older than 28004-006/38004-005,
- *    the U14F board is unable to provide reliable operations if the scsi
- *    request length exceeds 16Kbyte. When this length is exceeded the
- *    behavior is:
- *    - adapter_status equal 0x96 or 0xa3 or 0x93 or 0x94;
- *    - adapter_status equal 0 and target_status equal 2 on for all targets
- *      in the next operation following the reset.
- *    This sequence takes a long time (>3 seconds), so in the meantime
- *    the SD_TIMEOUT in sd.c could expire giving rise to scsi aborts
- *    (SD_TIMEOUT has been increased from 3 to 6 seconds in 1.1.31).
- *    Because of this I had to DISABLE_CLUSTERING and to work around the
- *    bus reset in the interrupt service routine, returning DID_BUS_BUSY
- *    so that the operations are retried without complains from the scsi.c
- *    code.
- *    Any reset of the scsi bus is going to kill tape operations, since
- *    no retry is allowed for tapes. Bus resets are more likely when the
- *    scsi bus is under heavy load.
- *    Requests using scatter/gather have a maximum length of 16 x 1024 bytes
- *    when DISABLE_CLUSTERING is in effect, but unscattered requests could be
- *    larger than 16Kbyte.
- *
- *    The new firmware has fixed all the above problems.
- *
- *  For U34F boards the latest bios prom is 38008-002 (BIOS rev. 2.01),
- *  the latest firmware prom is 28008-006. Older firmware 28008-005 has
- *  problems when using more than 16 scatter/gather lists.
- *
- *  The list of i/o ports to be probed can be totally replaced by the
- *  boot command line option: "u14-34f=port0,port1,port2,...", where the
- *  port0, port1... arguments are ISA/VESA addresses to be probed.
- *  For example using "u14-34f=0x230,0x340", the driver probes only the two
- *  addresses 0x230 and 0x340 in this order; "u14-34f=0" totally disables
- *  this driver.
- *
- *  After the optional list of detection probes, other possible command line
- *  options are:
- *
- *  et:y  use disk geometry returned by scsicam_bios_param;
- *  et:n  use disk geometry jumpered on the board;
- *  lc:y  enables linked commands;
- *  lc:n  disables linked commands;
- *  tm:0  disables tagged commands (same as tc:n);
- *  tm:1  use simple queue tags (same as tc:y);
- *  tm:2  use ordered queue tags (same as tc:2);
- *  of:y  enables old firmware support;
- *  of:n  disables old firmware support;
- *  mq:xx set the max queue depth to the value xx (2 <= xx <= 8).
- *
- *  The default value is: "u14-34f=lc:n,of:n,mq:8,tm:0,et:n".
- *  An example using the list of detection probes could be:
- *  "u14-34f=0x230,0x340,lc:y,tm:2,of:n,mq:4,et:n".
- *
- *  When loading as a module, parameters can be specified as well.
- *  The above example would be (use 1 in place of y and 0 in place of n):
- *
- *  modprobe u14-34f io_port=0x230,0x340 linked_comm=1 have_old_firmware=0 \
- *                max_queue_depth=4 ext_tran=0 tag_mode=2
- *
- *  ----------------------------------------------------------------------------
- *  In this implementation, linked commands are designed to work with any DISK
- *  or CD-ROM, since this linking has only the intent of clustering (time-wise)
- *  and reordering by elevator sorting commands directed to each device,
- *  without any relation with the actual SCSI protocol between the controller
- *  and the device.
- *  If Q is the queue depth reported at boot time for each device (also named
- *  cmds/lun) and Q > 2, whenever there is already an active command to the
- *  device all other commands to the same device  (up to Q-1) are kept waiting
- *  in the elevator sorting queue. When the active command completes, the
- *  commands in this queue are sorted by sector address. The sort is chosen
- *  between increasing or decreasing by minimizing the seek distance between
- *  the sector of the commands just completed and the sector of the first
- *  command in the list to be sorted.
- *  Trivial math assures that the unsorted average seek distance when doing
- *  random seeks over S sectors is S/3.
- *  When (Q-1) requests are uniformly distributed over S sectors, the average
- *  distance between two adjacent requests is S/((Q-1) + 1), so the sorted
- *  average seek distance for (Q-1) random requests over S sectors is S/Q.
- *  The elevator sorting hence divides the seek distance by a factor Q/3.
- *  The above pure geometric remarks are valid in all cases and the
- *  driver effectively reduces the seek distance by the predicted factor
- *  when there are Q concurrent read i/o operations on the device, but this
- *  does not necessarily results in a noticeable performance improvement:
- *  your mileage may vary....
- *
- *  Note: command reordering inside a batch of queued commands could cause
- *        wrong results only if there is at least one write request and the
- *        intersection (sector-wise) of all requests is not empty.
- *        When the driver detects a batch including overlapping requests
- *        (a really rare event) strict serial (pid) order is enforced.
- *  ----------------------------------------------------------------------------
- *
- *  The boards are named Ux4F0, Ux4F1,... according to the detection order.
- *
- *  In order to support multiple ISA boards in a reliable way,
- *  the driver sets host->wish_block = TRUE for all ISA boards.
