1998-11-30 OKUJI Yoshinori <okuji@kuicr.kyoto-u.ac.jp>

	Clean up linux emulation code to make it architecture-independent
	as much as possible.

	* linux: Renamed from linuxdev.
	* Makefile.in (objfiles): Add linux.o instead of linuxdev.o.
	(MAKE): New variable. Used for the linux.o target.
	* configure.in: Add AC_CHECK_TOOL(MAKE, make).
	* i386/i386/spl.h: Include <i386/ipl.h>, for compatibility with
	OSF Mach 3.0. Suggested by Elgin Lee <ehl@funghi.com>.
	* linux/src: Renamed from linux/linux.
	* linux/dev: Renamed from linux/mach.
	* linux/Drivers.in (AC_INIT): Use dev/include/linux/autoconf.h,
	instead of mach/include/linux/autoconf.h.
	* Makefile.in (all): Target ../linux.o instead of ../linuxdev.o.
	* linux/dev/drivers/block/genhd.c: Include <machine/spl.h> instead
	of <i386/ipl.h>.
	* linux/dev/drivers/net/auto_irq.c: Remove unneeded header files,
	<i386/ipl.h> and <i386/pic.h>.
	* linux/dev/init/main.c: Many i386-dependent codes moved to ...
	* linux/dev/arch/i386/irq.c: ... here.
	* linux/dev/arch/i386/setup.c: New file.
	* linux/dev/arch/i386/linux_emul.h: Likewise.
	* linux/dev/arch/i386/glue/timer.c: Merged into sched.c.
	* linux/dev/arch/i386/glue/sched.c: Include <machine/spl.h> instead
	of <i386/ipl.h>, and moved to ...
	* linux/dev/kernel/sched.c: ... here.
	* linux/dev/arch/i386/glue/block.c: Include <machine/spl.h> and
	<linux_emul.h>, instead of i386-dependent header files, and
	moved to ...
	* linux/dev/glue/blocl.c: ... here.
	* linux/dev/arch/i386/glue/net.c: Include <machine/spl.h> and
	<linux_emul.h>, instead of i386-dependent header files, and
	moved to ...
	* linux/dev/glue/net.c: ... here.
	* linux/dev/arch/i386/glue/misc.c: Remove `x86' and moved to ...
	* linux/dev/glue/misc.c: ... here.
	* linux/dev/arch/i386/glue/kmem.c: Moved to ...
	* linux/dev/glue/kmem.c: ... here.

+  BusLogic_ParseDriverOptions handles processing of BusLogic Driver Options
+  specifications.
+
+  BusLogic Driver Options may be specified either via the Linux Kernel Command
+  Line or via the Loadable Kernel Module Installation Facility.  Driver Options
+  for multiple host adapters may be specified either by separating the option
+  strings by a semicolon, or by specifying multiple "BusLogic=" strings on the
+  command line.  Individual option specifications for a single host adapter are
+  separated by commas.  The Probing and Debugging Options apply to all host
+  adapters whereas the remaining options apply individually only to the
+  selected host adapter.
+
+  The BusLogic Driver Probing Options comprise the following:
+
+  IO:<integer>
+
+    The "IO:" option specifies an ISA I/O Address to be probed for a non-PCI
+    MultiMaster Host Adapter.  If neither "IO:" nor "NoProbeISA" options are
+    specified, then the standard list of BusLogic MultiMaster ISA I/O Addresses
+    will be probed (0x330, 0x334, 0x230, 0x234, 0x130, and 0x134).  Multiple
+    "IO:" options may be specified to precisely determine the I/O Addresses to
+    be probed, but the probe order will always follow the standard list.
+
+  NoProbe
+
+    The "NoProbe" option disables all probing and therefore no BusLogic Host
+    Adapters will be detected.
+
+  NoProbeISA
+
+    The "NoProbeISA" option disables probing of the standard BusLogic ISA I/O
+    Addresses and therefore only PCI MultiMaster and FlashPoint Host Adapters
+    will be detected.
+
+  NoProbePCI
+
+    The "NoProbePCI" options disables the interrogation of PCI Configuration
+    Space and therefore only ISA Multimaster Host Adapters will be detected, as
+    well as PCI Multimaster Host Adapters that have their ISA Compatible I/O
+    Port set to "Primary" or "Alternate".
+
+  NoSortPCI
+
+    The "NoSortPCI" option forces PCI MultiMaster Host Adapters to be
+    enumerated in the order provided by the PCI BIOS, ignoring any setting of
+    the AutoSCSI "Use Bus And Device # For PCI Scanning Seq." option.
+
+  MultiMasterFirst
+
+    The "MultiMasterFirst" option forces MultiMaster Host Adapters to be probed
+    before FlashPoint Host Adapters.  By default, if both FlashPoint and PCI
+    MultiMaster Host Adapters are present, this driver will probe for
+    FlashPoint Host Adapters first unless the BIOS primary disk is controlled
+    by the first PCI MultiMaster Host Adapter, in which case MultiMaster Host
+    Adapters will be probed first.
+
+  FlashPointFirst
+
+    The "FlashPointFirst" option forces FlashPoint Host Adapters to be probed
+    before MultiMaster Host Adapters.
+
+  The BusLogic Driver Tagged Queuing Options allow for explicitly specifying
+  the Queue Depth and whether Tagged Queuing is permitted for each Target
+  Device (assuming that the Target Device supports Tagged Queuing).  The Queue
+  Depth is the number of SCSI Commands that are allowed to be concurrently
+  presented for execution (either to the Host Adapter or Target Device).  Note
+  that explicitly enabling Tagged Queuing may lead to problems; the option to
+  enable or disable Tagged Queuing is provided primarily to allow disabling
+  Tagged Queuing on Target Devices that do not implement it correctly.  The
+  following options are available:
+
+  QueueDepth:<integer>
+
+    The "QueueDepth:" or QD:" option specifies the Queue Depth to use for all
+    Target Devices that support Tagged Queuing, as well as the maximum Queue
+    Depth for devices that do not support Tagged Queuing.  If no Queue Depth
+    option is provided, the Queue Depth will be determined automatically based
+    on the Host Adapter's Total Queue Depth and the number, type, speed, and
+    capabilities of the detected Target Devices.  For Host Adapters that
+    require ISA Bounce Buffers, the Queue Depth is automatically set by default
+    to BusLogic_TaggedQueueDepthBB or BusLogic_UntaggedQueueDepthBB to avoid
+    excessive preallocation of DMA Bounce Buffer memory.  Target Devices that
+    do not support Tagged Queuing always have their Queue Depth set to
+    BusLogic_UntaggedQueueDepth or BusLogic_UntaggedQueueDepthBB, unless a
+    lower Queue Depth option is provided.  A Queue Depth of 1 automatically
+    disables Tagged Queuing.
+
+  QueueDepth:[<integer>,<integer>...]
+
+    The "QueueDepth:[...]" or "QD:[...]" option specifies the Queue Depth
+    individually for each Target Device.  If an <integer> is omitted, the
+    associated Target Device will have its Queue Depth selected automatically.
+
+  TaggedQueuing:Default
+
+    The "TaggedQueuing:Default" or "TQ:Default" option permits Tagged Queuing
+    based on the firmware version of the BusLogic Host Adapter and based on
+    whether the Queue Depth allows queuing multiple commands.
+
+  TaggedQueuing:Enable
+
+    The "TaggedQueuing:Enable" or "TQ:Enable" option enables Tagged Queuing for
+    all Target Devices on this Host Adapter, overriding any limitation that
+    would otherwise be imposed based on the Host Adapter firmware version.
+
+  TaggedQueuing:Disable
+
+    The "TaggedQueuing:Disable" or "TQ:Disable" option disables Tagged Queuing
+    for all Target Devices on this Host Adapter.
+
+  TaggedQueuing:<Target-Spec>
+
+    The "TaggedQueuing:<Target-Spec>" or "TQ:<Target-Spec>" option controls
+    Tagged Queuing individually for each Target Device.  <Target-Spec> is a
+    sequence of "Y", "N", and "X" characters.  "Y" enables Tagged Queuing, "N"
+    disables Tagged Queuing, and "X" accepts the default based on the firmware
+    version.  The first character refers to Target Device 0, the second to
+    Target Device 1, and so on; if the sequence of "Y", "N", and "X" characters
+    does not cover all the Target Devices, unspecified characters are assumed
+    to be "X".
+
+  The BusLogic Driver Error Recovery Option allows for explicitly specifying
+  the Error Recovery action to be performed when BusLogic_ResetCommand is
+  called due to a SCSI Command failing to complete successfully.  The following
+  options are available:
+
+  ErrorRecovery:Default
+
+    The "ErrorRecovery:Default" or "ER:Default" option selects between the Hard
+    Reset and Bus Device Reset options based on the recommendation of the SCSI
+    Subsystem.
+
+  ErrorRecovery:HardReset
+
+    The "ErrorRecovery:HardReset" or "ER:HardReset" option will initiate a Host
+    Adapter Hard Reset which also causes a SCSI Bus Reset.
+
+  ErrorRecovery:BusDeviceReset
+
+    The "ErrorRecovery:BusDeviceReset" or "ER:BusDeviceReset" option will send
+    a Bus Device Reset message to the individual Target Device causing the
+    error.  If Error Recovery is again initiated for this Target Device and no
+    SCSI Command to this Target Device has completed successfully since the Bus
+    Device Reset message was sent, then a Hard Reset will be attempted.
+
+  ErrorRecovery:None
+
+    The "ErrorRecovery:None" or "ER:None" option suppresses Error Recovery.
+    This option should only be selected if a SCSI Bus Reset or Bus Device Reset
+    will cause the Target Device or a critical operation to suffer a complete
+    and unrecoverable failure.
+
+  ErrorRecovery:<Target-Spec>
+
+    The "ErrorRecovery:<Target-Spec>" or "ER:<Target-Spec>" option controls
+    Error Recovery individually for each Target Device.  <Target-Spec> is a
+    sequence of "D", "H", "B", and "N" characters.  "D" selects Default, "H"
+    selects Hard Reset, "B" selects Bus Device Reset, and "N" selects None.
+    The first character refers to Target Device 0, the second to Target Device
+    1, and so on; if the sequence of "D", "H", "B", and "N" characters does not
+    cover all the possible Target Devices, unspecified characters are assumed
+    to be "D".
+
+  The BusLogic Driver Miscellaneous Options comprise the following:
+
+  BusSettleTime:<seconds>
+
+    The "BusSettleTime:" or "BST:" option specifies the Bus Settle Time in
+    seconds.  The Bus Settle Time is the amount of time to wait between a Host
+    Adapter Hard Reset which initiates a SCSI Bus Reset and issuing any SCSI
+    Commands.  If unspecified, it defaults to BusLogic_DefaultBusSettleTime.
+
+  InhibitTargetInquiry
+
+    The "InhibitTargetInquiry" option inhibits the execution of an Inquire
+    Target Devices or Inquire Installed Devices command on MultiMaster Host
+    Adapters.  This may be necessary with some older Target Devices that do not
+    respond correctly when Logical Units above 0 are addressed.
+
+  The BusLogic Driver Debugging Options comprise the following:
+
+  TraceProbe
+
+    The "TraceProbe" option enables tracing of Host Adapter Probing.
+
+  TraceHardwareReset
+
+    The "TraceHardwareReset" option enables tracing of Host Adapter Hardware
+    Reset.
+
+  TraceConfiguration
+
+    The "TraceConfiguration" option enables tracing of Host Adapter
+    Configuration.
+
+  TraceErrors
+
+    The "TraceErrors" option enables tracing of SCSI Commands that return an
+    error from the Target Device.  The CDB and Sense Data will be printed for
+    each SCSI Command that fails.
+
+  Debug
+
+    The "Debug" option enables all debugging options.
+
+  The following examples demonstrate setting the Queue Depth for Target Devices
+  1 and 2 on the first host adapter to 7 and 15, the Queue Depth for all Target
+  Devices on the second host adapter to 31, and the Bus Settle Time on the
+  second host adapter to 30 seconds.
