  17                                 INTRODUCTION
  19BusLogic, Inc. designed and manufactured a variety of high performance SCSI
  20host adapters which share a common programming interface across a diverse
  21collection of bus architectures by virtue of their MultiMaster ASIC technology.
  22BusLogic was acquired by Mylex Corporation in February 1996, but the products
  23supported by this driver originated under the BusLogic name and so that name is
  24retained in the source code and documentation.
  26This driver supports all present BusLogic MultiMaster Host Adapters, and should
  27support any future MultiMaster designs with little or no modification.  More
  28recently, BusLogic introduced the FlashPoint Host Adapters, which are less
  29costly and rely on the host CPU, rather than including an onboard processor.
  30Despite not having an onboard CPU, the FlashPoint Host Adapters perform very
  31well and have very low command latency.  BusLogic has recently provided me with
  32the FlashPoint Driver Developer's Kit, which comprises documentation and freely
  33redistributable source code for the FlashPoint SCCB Manager.  The SCCB Manager
  34is the library of code that runs on the host CPU and performs functions
  35analogous to the firmware on the MultiMaster Host Adapters.  Thanks to their
  36having provided the SCCB Manager, this driver now supports the FlashPoint Host
  37Adapters as well.
  39My primary goals in writing this completely new BusLogic driver for Linux are
  40to achieve the full performance that BusLogic SCSI Host Adapters and modern
  41SCSI peripherals are capable of, and to provide a highly robust driver that can
  42be depended upon for high performance mission critical applications.  All of
  43the major performance features can be configured from the Linux kernel command
  44line or at module initialization time, allowing individual installations to
  45tune driver performance and error recovery to their particular needs.
  47The latest information on Linux support for BusLogic SCSI Host Adapters, as
  48well as the most recent release of this driver and the latest firmware for the
  49BT-948/958/958D, will always be available from my Linux Home Page at URL
  52Bug reports should be sent via electronic mail to "".  Please
  53include with the bug report the complete configuration messages reported by the
  54driver and SCSI subsystem at startup, along with any subsequent system messages
  55relevant to SCSI operations, and a detailed description of your system's
  56hardware configuration.
  58Mylex has been an excellent company to work with and I highly recommend their
  59products to the Linux community.  In November 1995, I was offered the
  60opportunity to become a beta test site for their latest MultiMaster product,
  61the BT-948 PCI Ultra SCSI Host Adapter, and then again for the BT-958 PCI Wide
  62Ultra SCSI Host Adapter in January 1996.  This was mutually beneficial since
  63Mylex received a degree and kind of testing that their own testing group cannot
  64readily achieve, and the Linux community has available high performance host
  65adapters that have been well tested with Linux even before being brought to
  66market.  This relationship has also given me the opportunity to interact
  67directly with their technical staff, to understand more about the internal
  68workings of their products, and in turn to educate them about the needs and
  69potential of the Linux community.
  71More recently, Mylex has reaffirmed the company's interest in supporting the
  72Linux community, and I am now working on a Linux driver for the DAC960 PCI RAID
  73Controllers.  Mylex's interest and support is greatly appreciated.
  75Unlike some other vendors, if you contact Mylex Technical Support with a
  76problem and are running Linux, they will not tell you that your use of their
  77products is unsupported.  Their latest product marketing literature even states
  78"Mylex SCSI host adapters are compatible with all major operating systems
  79including: ... Linux ...".

  89                                DRIVER FEATURES
  91o Configuration Reporting and Testing
  93  During system initialization, the driver reports extensively on the host
  94  adapter hardware configuration, including the synchronous transfer parameters
  95  requested and negotiated with each target device.  AutoSCSI settings for
  96  Synchronous Negotiation, Wide Negotiation, and Disconnect/Reconnect are
  97  reported for each target device, as well as the status of Tagged Queuing.
  98  If the same setting is in effect for all target devices, then a single word
  99  or phrase is used; otherwise, a letter is provided for each target device to
 100  indicate the individual status.  The following examples
 101  should clarify this reporting format:
 103    Synchronous Negotiation: Ultra
 105      Synchronous negotiation is enabled for all target devices and the host
 106      adapter will attempt to negotiate for 20.0 mega-transfers/second.
 108    Synchronous Negotiation: Fast
 110      Synchronous negotiation is enabled for all target devices and the host
 111      adapter will attempt to negotiate for 10.0 mega-transfers/second.
 113    Synchronous Negotiation: Slow
 115      Synchronous negotiation is enabled for all target devices and the host
 116      adapter will attempt to negotiate for 5.0 mega-transfers/second.
 118    Synchronous Negotiation: Disabled
 120      Synchronous negotiation is disabled and all target devices are limited to
 121      asynchronous operation.
 123    Synchronous Negotiation: UFSNUUU#UUUUUUUU
 125      Synchronous negotiation to Ultra speed is enabled for target devices 0
 126      and 4 through 15, to Fast speed for target device 1, to Slow speed for
 127      target device 2, and is not permitted to target device 3.  The host
 128      adapter's SCSI ID is represented by the "#".
 130    The status of Wide Negotiation, Disconnect/Reconnect, and Tagged Queuing
 131    are reported as "Enabled", Disabled", or a sequence of "Y" and "N" letters.
 133o Performance Features
 135  BusLogic SCSI Host Adapters directly implement SCSI-2 Tagged Queuing, and so
 136  support has been included in the driver to utilize tagged queuing with any
 137  target devices that report having the tagged queuing capability.  Tagged
 138  queuing allows for multiple outstanding commands to be issued to each target
 139  device or logical unit, and can improve I/O performance substantially.  In
 140  addition, BusLogic's Strict Round Robin Mode is used to optimize host adapter
 141  performance, and scatter/gather I/O can support as many segments as can be
 142  effectively utilized by the Linux I/O subsystem.  Control over the use of
 143  tagged queuing for each target device as well as individual selection of the
 144  tagged queue depth is available through driver options provided on the kernel
 145  command line or at module initialization time.  By default, the queue depth
 146  is determined automatically based on the host adapter's total queue depth and
 147  the number, type, speed, and capabilities of the target devices found.  In
 148  addition, tagged queuing is automatically disabled whenever the host adapter
 149  firmware version is known not to implement it correctly, or whenever a tagged
 150  queue depth of 1 is selected.  Tagged queuing is also disabled for individual
 151  target devices if disconnect/reconnect is disabled for that device.
 153o Robustness Features
 155  The driver implements extensive error recovery procedures.  When the higher
 156  level parts of the SCSI subsystem request that a timed out command be reset,
 157  a selection is made between a full host adapter hard reset and SCSI bus reset
 158  versus sending a bus device reset message to the individual target device
 159  based on the recommendation of the SCSI subsystem.  Error recovery strategies
 160  are selectable through driver options individually for each target device,
 161  and also include sending a bus device reset to the specific target device
 162  associated with the command being reset, as well as suppressing error
 163  recovery entirely to avoid perturbing an improperly functioning device.  If
 164  the bus device reset error recovery strategy is selected and sending a bus
 165  device reset does not restore correct operation, the next command that is
 166  reset will force a full host adapter hard reset and SCSI bus reset.  SCSI bus
 167  resets caused by other devices and detected by the host adapter are also
 168  handled by issuing a soft reset to the host adapter and re-initialization.
 169  Finally, if tagged queuing is active and more than one command reset occurs
 170  in a 10 minute interval, or if a command reset occurs within the first 10
 171  minutes of operation, then tagged queuing will be disabled for that target
 172  device.  These error recovery options improve overall system robustness by
 173  preventing individual errant devices from causing the system as a whole to
 174  lock up or crash, and thereby allowing a clean shutdown and restart after the
 175  offending component is removed.
 177o PCI Configuration Support
 179  On PCI systems running kernels compiled with PCI BIOS support enabled, this
 180  driver will interrogate the PCI configuration space and use the I/O port
 181  addresses assigned by the system BIOS, rather than the ISA compatible I/O
 182  port addresses.  The ISA compatible I/O port address is then disabled by the
 183  driver.  On PCI systems it is also recommended that the AutoSCSI utility be
 184  used to disable the ISA compatible I/O port entirely as it is not necessary.
 185  The ISA compatible I/O port is disabled by default on the BT-948/958/958D.
 187o /proc File System Support
 189  Copies of the host adapter configuration information together with updated
 190  data transfer and error recovery statistics are available through the
 191  /proc/scsi/BusLogic/<N> interface.
 193o Shared Interrupts Support
 195  On systems that support shared interrupts, any number of BusLogic Host
 196  Adapters may share the same interrupt request channel.
 199                            SUPPORTED HOST ADAPTERS

 202the date of this document.  It is recommended that anyone purchasing a BusLogic

 253AMI FastDisk Host Adapters that are true BusLogic MultiMaster clones are also
 254supported by this driver.
 256BusLogic SCSI Host Adapters are available packaged both as bare boards and as
 257retail kits.  The BT- model numbers above refer to the bare board packaging.
 258The retail kit model numbers are found by replacing BT- with KT- in the above
 259list.  The retail kit includes the bare board and manual as well as cabling and
 260driver media and documentation that are not provided with bare boards.
 263                         FLASHPOINT INSTALLATION NOTES
 265o RAIDPlus Support
 267  FlashPoint Host Adapters now include RAIDPlus, Mylex's bootable software
 268  RAID.  RAIDPlus is not supported on Linux, and there are no plans to support
 269  it.  The MD driver in Linux 2.0 provides for concatenation (LINEAR) and
 270  striping (RAID-0), and support for mirroring (RAID-1), fixed parity (RAID-4),
 271  and distributed parity (RAID-5) is available separately.  The built-in Linux
 272  RAID support is generally more flexible and is expected to perform better
 273  than RAIDPlus, so there is little impetus to include RAIDPlus support in the
 274  BusLogic driver.
 276o Enabling UltraSCSI Transfers
 278  FlashPoint Host Adapters ship with their configuration set to "Factory
 279  Default" settings that are conservative and do not allow for UltraSCSI speed
 280  to be negotiated.  This results in fewer problems when these host adapters
 281  are installed in systems with cabling or termination that is not sufficient
 282  for UltraSCSI operation, or where existing SCSI devices do not properly
 283  respond to synchronous transfer negotiation for UltraSCSI speed.  AutoSCSI
 284  may be used to load "Optimum Performance" settings which allow UltraSCSI
 285  speed to be negotiated with all devices, or UltraSCSI speed can be enabled on
 286  an individual basis.  It is recommended that SCAM be manually disabled after
 287  the "Optimum Performance" settings are loaded.
 290                      BT-948/958/958D INSTALLATION NOTES
 292The BT-948/958/958D PCI Ultra SCSI Host Adapters have some features which may
 293require attention in some circumstances when installing Linux.
 295o PCI I/O Port Assignments
 297  When configured to factory default settings, the BT-948/958/958D will only
 298  recognize the PCI I/O port assignments made by the motherboard's PCI BIOS.
 299  The BT-948/958/958D will not respond to any of the ISA compatible I/O ports
 300  that previous BusLogic SCSI Host Adapters respond to.  This driver supports
 301  the PCI I/O port assignments, so this is the preferred configuration.
 302  However, if the obsolete BusLogic driver must be used for any reason, such as
 303  a Linux distribution that does not yet use this driver in its boot kernel,
 304  BusLogic has provided an AutoSCSI configuration option to enable a legacy ISA
 305  compatible I/O port.
 307  To enable this backward compatibility option, invoke the AutoSCSI utility via
 308  Ctrl-B at system startup and select "Adapter Configuration", "View/Modify
 309  Configuration", and then change the "ISA Compatible Port" setting from
 310  "Disable" to "Primary" or "Alternate".  Once this driver has been installed,
 311  the "ISA Compatible Port" option should be set back to "Disable" to avoid
 312  possible future I/O port conflicts.  The older BT-946C/956C/956CD also have
 313  this configuration option, but the factory default setting is "Primary".
 315o PCI Slot Scanning Order
 317  In systems with multiple BusLogic PCI Host Adapters, the order in which the
 318  PCI slots are scanned may appear reversed with the BT-948/958/958D as
 319  compared to the BT-946C/956C/956CD.  For booting from a SCSI disk to work
 320  correctly, it is necessary that the host adapter's BIOS and the kernel agree
 321  on which disk is the boot device, which requires that they recognize the PCI
 322  host adapters in the same order.  The motherboard's PCI BIOS provides a
 323  standard way of enumerating the PCI host adapters, which is used by the Linux
 324  kernel.  Some PCI BIOS implementations enumerate the PCI slots in order of
 325  increasing bus number and device number, while others do so in the opposite
 326  direction.
 328  Unfortunately, Microsoft decided that Windows 95 would always enumerate the
 329  PCI slots in order of increasing bus number and device number regardless of
 330  the PCI BIOS enumeration, and requires that their scheme be supported by the
 331  host adapter's BIOS to receive Windows 95 certification.  Therefore, the
 332  factory default settings of the BT-948/958/958D enumerate the host adapters
 333  by increasing bus number and device number.  To disable this feature, invoke
 334  the AutoSCSI utility via Ctrl-B at system startup and select "Adapter
 335  Configuration", "View/Modify Configuration", press Ctrl-F10, and then change
 336  the "Use Bus And Device # For PCI Scanning Seq." option to OFF.
 338  This driver will interrogate the setting of the PCI Scanning Sequence option
 339  so as to recognize the host adapters in the same order as they are enumerated
 340  by the host adapter's BIOS.
 342o Enabling UltraSCSI Transfers
 344  The BT-948/958/958D ship with their configuration set to "Factory Default"
 345  settings that are conservative and do not allow for UltraSCSI speed to be
 346  negotiated.  This results in fewer problems when these host adapters are
 347  installed in systems with cabling or termination that is not sufficient for
 348  UltraSCSI operation, or where existing SCSI devices do not properly respond
 349  to synchronous transfer negotiation for UltraSCSI speed.  AutoSCSI may be
 350  used to load "Optimum Performance" settings which allow UltraSCSI speed to be
 351  negotiated with all devices, or UltraSCSI speed can be enabled on an
 352  individual basis.  It is recommended that SCAM be manually disabled after the
 353  "Optimum Performance" settings are loaded.
 356                                DRIVER OPTIONS
 358BusLogic Driver Options may be specified either via the Linux Kernel Command
 359Line or via the Loadable Kernel Module Installation Facility.  Driver Options
 360for multiple host adapters may be specified either by separating the option
 361strings by a semicolon, or by specifying multiple "BusLogic=" strings on the
 362command line.  Individual option specifications for a single host adapter are
 363separated by commas.  The Probing and Debugging Options apply to all host
 364adapters whereas the remaining options apply individually only to the
 365selected host adapter.
 367The BusLogic Driver Probing Options comprise the following:
 371  The "IO:" option specifies an ISA I/O Address to be probed for a non-PCI
 372  MultiMaster Host Adapter.  If neither "IO:" nor "NoProbeISA" options are
 373  specified, then the standard list of BusLogic MultiMaster ISA I/O Addresses
 374  will be probed (0x330, 0x334, 0x230, 0x234, 0x130, and 0x134).  Multiple
 375  "IO:" options may be specified to precisely determine the I/O Addresses to
 376  be probed, but the probe order will always follow the standard list.
 380  The "NoProbe" option disables all probing and therefore no BusLogic Host
 381  Adapters will be detected.
 385  The "NoProbeISA" option disables probing of the standard BusLogic ISA I/O
 386  Addresses and therefore only PCI MultiMaster and FlashPoint Host Adapters
 387  will be detected.
 391  The "NoProbePCI" options disables the interrogation of PCI Configuration
 392  Space and therefore only ISA Multimaster Host Adapters will be detected, as
 393  well as PCI Multimaster Host Adapters that have their ISA Compatible I/O
 394  Port set to "Primary" or "Alternate".
 398  The "NoSortPCI" option forces PCI MultiMaster Host Adapters to be
 399  enumerated in the order provided by the PCI BIOS, ignoring any setting of
 400  the AutoSCSI "Use Bus And Device # For PCI Scanning Seq." option.
 404  The "MultiMasterFirst" option forces MultiMaster Host Adapters to be probed
 405  before FlashPoint Host Adapters.  By default, if both FlashPoint and PCI
 406  MultiMaster Host Adapters are present, this driver will probe for
 407  FlashPoint Host Adapters first unless the BIOS primary disk is controlled
 408  by the first PCI MultiMaster Host Adapter, in which case MultiMaster Host
 409  Adapters will be probed first.
 413  The "FlashPointFirst" option forces FlashPoint Host Adapters to be probed
 414  before MultiMaster Host Adapters.
 416The BusLogic Driver Tagged Queuing Options allow for explicitly specifying
 417the Queue Depth and whether Tagged Queuing is permitted for each Target
 418Device (assuming that the Target Device supports Tagged Queuing).  The Queue
 419Depth is the number of SCSI Commands that are allowed to be concurrently
 420presented for execution (either to the Host Adapter or Target Device).  Note
 421that explicitly enabling Tagged Queuing may lead to problems; the option to
 422enable or disable Tagged Queuing is provided primarily to allow disabling
 423Tagged Queuing on Target Devices that do not implement it correctly.  The
 424following options are available:
 428  The "QueueDepth:" or QD:" option specifies the Queue Depth to use for all
 429  Target Devices that support Tagged Queuing, as well as the maximum Queue
 430  Depth for devices that do not support Tagged Queuing.  If no Queue Depth
 431  option is provided, the Queue Depth will be determined automatically based
 432  on the Host Adapter's Total Queue Depth and the number, type, speed, and
 433  capabilities of the detected Target Devices.  For Host Adapters that
 434  require ISA Bounce Buffers, the Queue Depth is automatically set by default
 435  to BusLogic_TaggedQueueDepthBB or BusLogic_UntaggedQueueDepthBB to avoid
 436  excessive preallocation of DMA Bounce Buffer memory.  Target Devices that
 437  do not support Tagged Queuing always have their Queue Depth set to
 438  BusLogic_UntaggedQueueDepth or BusLogic_UntaggedQueueDepthBB, unless a
 439  lower Queue Depth option is provided.  A Queue Depth of 1 automatically
 440  disables Tagged Queuing.
 444  The "QueueDepth:[...]" or "QD:[...]" option specifies the Queue Depth
 445  individually for each Target Device.  If an <integer> is omitted, the
 446  associated Target Device will have its Queue Depth selected automatically.
 450  The "TaggedQueuing:Default" or "TQ:Default" option permits Tagged Queuing
 451  based on the firmware version of the BusLogic Host Adapter and based on
 452  whether the Queue Depth allows queuing multiple commands.
 456  The "TaggedQueuing:Enable" or "TQ:Enable" option enables Tagged Queuing for
 457  all Target Devices on this Host Adapter, overriding any limitation that
 458  would otherwise be imposed based on the Host Adapter firmware version.
 462  The "TaggedQueuing:Disable" or "TQ:Disable" option disables Tagged Queuing
 463  for all Target Devices on this Host Adapter.
 467  The "TaggedQueuing:<Target-Spec>" or "TQ:<Target-Spec>" option controls
 468  Tagged Queuing individually for each Target Device.  <Target-Spec> is a
 469  sequence of "Y", "N", and "X" characters.  "Y" enables Tagged Queuing, "N"
 470  disables Tagged Queuing, and "X" accepts the default based on the firmware
 471  version.  The first character refers to Target Device 0, the second to
 472  Target Device 1, and so on; if the sequence of "Y", "N", and "X" characters
 473  does not cover all the Target Devices, unspecified characters are assumed
 474  to be "X".
 476The BusLogic Driver Miscellaneous Options comprise the following:
 480  The "BusSettleTime:" or "BST:" option specifies the Bus Settle Time in
 481  seconds.  The Bus Settle Time is the amount of time to wait between a Host
 482  Adapter Hard Reset which initiates a SCSI Bus Reset and issuing any SCSI
 483  Commands.  If unspecified, it defaults to BusLogic_DefaultBusSettleTime.
 487  The "InhibitTargetInquiry" option inhibits the execution of an Inquire
 488  Target Devices or Inquire Installed Devices command on MultiMaster Host
 489  Adapters.  This may be necessary with some older Target Devices that do not
 490  respond correctly when Logical Units above 0 are addressed.
 492The BusLogic Driver Debugging Options comprise the following:
 496  The "TraceProbe" option enables tracing of Host Adapter Probing.
 500  The "TraceHardwareReset" option enables tracing of Host Adapter Hardware
 501  Reset.
 505  The "TraceConfiguration" option enables tracing of Host Adapter
 506  Configuration.
 510  The "TraceErrors" option enables tracing of SCSI Commands that return an
 511  error from the Target Device.  The CDB and Sense Data will be printed for
 512  each SCSI Command that fails.
 516  The "Debug" option enables all debugging options.
 518The following examples demonstrate setting the Queue Depth for Target Devices
 5191 and 2 on the first host adapter to 7 and 15, the Queue Depth for all Target
 520Devices on the second host adapter to 31, and the Bus Settle Time on the
 521second host adapter to 30 seconds.
 523Linux Kernel Command Line:
 525  linux BusLogic=QueueDepth:[,7,15];QueueDepth:31,BusSettleTime:30
 527LILO Linux Boot Loader (in /etc/lilo.conf):
 529  append = "BusLogic=QueueDepth:[,7,15];QueueDepth:31,BusSettleTime:30"
 531INSMOD Loadable Kernel Module Installation Facility:
 533  insmod BusLogic.o \
 534      'BusLogic="QueueDepth:[,7,15];QueueDepth:31,BusSettleTime:30"'
 536NOTE: Module Utilities 2.1.71 or later is required for correct parsing
 537      of driver options containing commas.
 540                              DRIVER INSTALLATION
 542This distribution was prepared for Linux kernel version 2.0.35, but should be
 543compatible with 2.0.4 or any later 2.0 series kernel.
 545To install the new BusLogic SCSI driver, you may use the following commands,
 546replacing "/usr/src" with wherever you keep your Linux kernel source tree:
 548  cd /usr/src
 549  tar -xvzf BusLogic-2.0.15.tar.gz
 550  mv README.* LICENSE.* BusLogic.[ch] FlashPoint.c linux/drivers/scsi
 551  patch -p0 < BusLogic.patch (only for 2.0.33 and below)
 552  cd linux
 553  make config
 554  make zImage
 556Then install "arch/i386/boot/zImage" as your standard kernel, run lilo if
 557appropriate, and reboot.
