+ 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.
