BusLogic_ParseDriverOptions handles processing of BusLogic Driver Options
|
4467 |
|
|
specifications.
|
4468 |
|
|
|
4469 |
|
|
BusLogic Driver Options may be specified either via the Linux Kernel Command
|
4470 |
|
|
Line or via the Loadable Kernel Module Installation Facility. Driver Options
|
4471 |
|
|
for multiple host adapters may be specified either by separating the option
|
4472 |
|
|
strings by a semicolon, or by specifying multiple "BusLogic=" strings on the
|
4473 |
|
|
command line. Individual option specifications for a single host adapter are
|
4474 |
|
|
separated by commas. The Probing and Debugging Options apply to all host
|
4475 |
|
|
adapters whereas the remaining options apply individually only to the
|
4476 |
|
|
selected host adapter.
|
4477 |
|
|
|
4478 |
|
|
The BusLogic Driver Probing Options comprise the following:
|
4479 |
|
|
|
4480 |
|
|
IO:<integer>
|
4481 |
|
|
|
4482 |
|
|
The "IO:" option specifies an ISA I/O Address to be probed for a non-PCI
|
4483 |
|
|
MultiMaster Host Adapter. If neither "IO:" nor "NoProbeISA" options are
|
4484 |
|
|
specified, then the standard list of BusLogic MultiMaster ISA I/O Addresses
|
4485 |
|
|
will be probed (0x330, 0x334, 0x230, 0x234, 0x130, and 0x134). Multiple
|
4486 |
|
|
"IO:" options may be specified to precisely determine the I/O Addresses to
|
4487 |
|
|
be probed, but the probe order will always follow the standard list.
|
4488 |
|
|
|
4489 |
|
|
NoProbe
|
4490 |
|
|
|
4491 |
|
|
The "NoProbe" option disables all probing and therefore no BusLogic Host
|
4492 |
|
|
Adapters will be detected.
|
4493 |
|
|
|
4494 |

4496 |
|
|
The "NoProbeISA" option disables probing of the standard BusLogic ISA I/O
|
4497 |
|
|
Addresses and therefore only PCI MultiMaster and FlashPoint Host Adapters
|
4498 |
|
|
will be detected.
|
4499 |
|
|
|
4500 |
|
|
NoProbePCI
|
4501 |
|
|
|
4502 |
|
|
The "NoProbePCI" options disables the interrogation of PCI Configuration
|
4503 |
|
|
Space and therefore only ISA Multimaster Host Adapters will be detected, as
|
4504 |
|
|
well as PCI Multimaster Host Adapters that have their ISA Compatible I/O
|
4505 |
|
|
Port set to "Primary" or "Alternate".
|
4506 |
|
|
|
4507 |
|
|
NoSortPCI
|
4508 |
|
|
|
4509 |
|
|
The "NoSortPCI" option forces PCI MultiMaster Host Adapters to be
|
4510 |
|
|
enumerated in the order provided by the PCI BIOS, ignoring any setting of
|
4511 |
|
|
the AutoSCSI "Use Bus And Device # For PCI Scanning Seq." option.
|
4512 |
|
|
|
4513 |
|
|
MultiMasterFirst
|
4514 |
|
|
|
4515 |
|
|
The "MultiMasterFirst" option forces MultiMaster Host Adapters to be probed
|
4516 |
|
|
before FlashPoint Host Adapters. By default, if both FlashPoint and PCI
|
4517 |
|
|
MultiMaster Host Adapters are present, this driver will probe for
|
4518 |
|
|
FlashPoint Host Adapters first unless the BIOS primary disk is controlled
|
4519 |
|
|
by the first PCI MultiMaster Host Adapter, in which case MultiMaster Host
|
4520 |
|
|
Adapters will be probed first.
|
4521 |
|
|
|
4522 |
|
|
FlashPointFirst
|
4523 |
|
|
|
4524 |
|
|
The "FlashPointFirst" option forces FlashPoint Host Adapters to be probed
|
4525 |
|
|
before MultiMaster Host Adapters.
|
4526 |
|
|
|
4527 |
|
|
The BusLogic Driver Tagged Queuing Options allow for explicitly specifying
|
4528 |
|
|
the Queue Depth and whether Tagged Queuing is permitted for each Target
|
4529 |
|
|
Device (assuming that the Target Device supports Tagged Queuing). The Queue
|
4530 |
|
|
Depth is the number of SCSI Commands that are allowed to be concurrently
|
4531 |
|
|
presented for execution (either to the Host Adapter or Target Device). Note
|
4532 |
|
|
that explicitly enabling Tagged Queuing may lead to problems; the option to
|
4533 |
|
|
enable or disable Tagged Queuing is provided primarily to allow disabling
|
4534 |
|
|
Tagged Queuing on Target Devices that do not implement it correctly. The
|
4535 |
|
|
following options are available:
|
4536 |
|
|
|
4537 |
|
|
QueueDepth:<integer>
|
4538 |
|
|
|
4539 |
|
|
The "QueueDepth:" or QD:" option specifies the Queue Depth to use for all
|
4540 |
|
|
Target Devices that support Tagged Queuing, as well as the maximum Queue
|
4541 |
|
|
Depth for devices that do not support Tagged Queuing. If no Queue Depth
|
4542 |
|
|
option is provided, the Queue Depth will be determined automatically based
|
4543 |
|
|
on the Host Adapter's Total Queue Depth and the number, type, speed, and
|
4544 |
|
|
capabilities of the detected Target Devices. For Host Adapters that
|
4545 |
|
|
require ISA Bounce Buffers, the Queue Depth is automatically set by default
|
4546 |
|
|
to BusLogic_TaggedQueueDepthBB or BusLogic_UntaggedQueueDepthBB to avoid
|
4547 |
|
|
excessive preallocation of DMA Bounce Buffer memory. Target Devices that
|
4548 |
|
|
do not support Tagged Queuing always have their Queue Depth set to
|
4549 |
|
|
BusLogic_UntaggedQueueDepth or BusLogic_UntaggedQueueDepthBB, unless a
|
4550 |
|
|
lower Queue Depth option is provided. A Queue Depth of 1 automatically
|
4551 |
|
|
disables Tagged Queuing.
|
4552 |
|
|
|
4553 |
|
|
QueueDepth:[<integer>,<integer>...]
|
4554 |
|
|
|
4555 |
|
|
The "QueueDepth:[...]" or "QD:[...]" option specifies the Queue Depth
|
4556 |
|
|
individually for each Target Device. If an <integer> is omitted, the
|
4557 |
|
|
associated Target Device will have its Queue Depth selected automatically.
|
4558 |
|
|
|
4559 |
|
|
TaggedQueuing:Default
|
4560 |
|
|
|
4561 |
|
|
The "TaggedQueuing:Default" or "TQ:Default" option permits Tagged Queuing
|
4562 |
|
|
based on the firmware version of the BusLogic Host Adapter and based on
|
4563 |
|
|
whether the Queue Depth allows queuing multiple commands.
|
4564 |
|
|
|
4565 |
|
|
TaggedQueuing:Enable
|
4566 |
|
|
|
4567 |
|
|
The "TaggedQueuing:Enable" or "TQ:Enable" option enables Tagged Queuing for
|
4568 |
|
|
all Target Devices on this Host Adapter, overriding any limitation that
|
4569 |
|
|
would otherwise be imposed based on the Host Adapter firmware version.
|
4570 |
|
|
|
4571 |
|
|
TaggedQueuing:Disable
|
4572 |
|
|
|
4573 |
|
|
The "TaggedQueuing:Disable" or "TQ:Disable" option disables Tagged Queuing
|
4574 |
|
|
for all Target Devices on this Host Adapter.
|
4575 |
|
|
|
4576 |
|
|
TaggedQueuing:<Target-Spec>
|
4577 |
|
|
|
4578 |
|
|
The "TaggedQueuing:<Target-Spec>" or "TQ:<Target-Spec>" option controls
|
4579 |
|
|
Tagged Queuing individually for each Target Device. <Target-Spec> is a
|
4580 |
|
|
sequence of "Y", "N", and "X" characters. "Y" enables Tagged Queuing, "N"
|
4581 |
|
|
disables Tagged Queuing, and "X" accepts the default based on the firmware
|
4582 |
|
|
version. The first character refers to Target Device 0, the second to
|
4583 |
|
|
Target Device 1, and so on; if the sequence of "Y", "N", and "X" characters
|
4584 |
|
|
does not cover all the Target Devices, unspecified characters are assumed
|
4585 |
|
|
to be "X".
|
4586 |
|
|
|
4587 |
|
|
The BusLogic Driver Error Recovery Option allows for explicitly specifying
|
4588 |
|
|
the Error Recovery action to be performed when BusLogic_ResetCommand is
|
4589 |
|
|
called due to a SCSI Command failing to complete successfully. The following
|
4590 |
|
|
options are available:
|
4591 |
|
|
|
4592 |
|
|
ErrorRecovery:Default
|
4593 |
|
|
|
4594 |
|
|
The "ErrorRecovery:Default" or "ER:Default" option selects between the Hard
|
4595 |
|
|
Reset and Bus Device Reset options based on the recommendation of the SCSI
|
4596 |
|
|
Subsystem.
|
4597 |
|
|
|
4598 |
|
|
ErrorRecovery:HardReset
|
4599 |
|
|
|
4600 |
|
|
The "ErrorRecovery:HardReset" or "ER:HardReset" option will initiate a Host
|
4601 |
|
|
Adapter Hard Reset which also causes a SCSI Bus Reset.
|
4602 |
|
|
|
4603 |
|
|
ErrorRecovery:BusDeviceReset
|
4604 |
|
|
|
4605 |
|
|
The "ErrorRecovery:BusDeviceReset" or "ER:BusDeviceReset" option will send
|
4606 |
|
|
a Bus Device Reset message to the individual Target Device causing the
|
4607 |
|
|
error. If Error Recovery is again initiated for this Target Device and no
|
4608 |
|
|
SCSI Command to this Target Device has completed successfully since the Bus
|
4609 |
|
|
Device Reset message was sent, then a Hard Reset will be attempted.
|
4610 |
|
|
|
4611 |
|
|
ErrorRecovery:None
|
4612 |
|
|
|
4613 |
|
|
The "ErrorRecovery:None" or "ER:None" option suppresses Error Recovery.
|
4614 |
|
|
This option should only be selected if a SCSI Bus Reset or Bus Device Reset
|
4615 |
|
|
will cause the Target Device or a critical operation to suffer a complete
|
4616 |
|
|
and unrecoverable failure.
|
4617 |
|
|
|
4618 |
|
|
ErrorRecovery:<Target-Spec>
|
4619 |
|
|
|
4620 |
|
|
The "ErrorRecovery:<Target-Spec>" or "ER:<Target-Spec>" option controls
|
4621 |
|
|
Error Recovery individually for each Target Device. <Target-Spec> is a
|
4622 |
|
|
sequence of "D", "H", "B", and "N" characters. "D" selects Default, "H"
|
4623 |
|
|
selects Hard Reset, "B" selects Bus Device Reset, and "N" selects None.
|
4624 |
|
|
The first character refers to Target Device 0, the second to Target Device
|
4625 |
|
|
1, and so on; if the sequence of "D", "H", "B", and "N" characters does not
|
4626 |
|
|
cover all the possible Target Devices, unspecified characters are assumed
|
4627 |
|
|
to be "D".
|
4628 |
|
|
|
4629 |
|
|
The BusLogic Driver Miscellaneous Options comprise the following:
|
4630 |
|
|
|
4631 |
|
|
BusSettleTime:<seconds>
|
4632 |
|
|
|
4633 |
|
|
The "BusSettleTime:" or "BST:" option specifies the Bus Settle Time in
|
4634 |
|
|
seconds. The Bus Settle Time is the amount of time to wait between a Host
|
4635 |
|
|
Adapter Hard Reset which initiates a SCSI Bus Reset and issuing any SCSI
|
4636 |
|
|
Commands. If unspecified, it defaults to BusLogic_DefaultBusSettleTime.
|
4637 |
|
|
|
4638 |
|
|
InhibitTargetInquiry
|
4639 |
|
|
|
4640 |
|
|
The "InhibitTargetInquiry" option inhibits the execution of an Inquire
|
4641 |
|
|
Target Devices or Inquire Installed Devices command on MultiMaster Host
|
4642 |
|
|
Adapters. This may be necessary with some older Target Devices that do not
|
4643 |
|
|
respond correctly when Logical Units above 0 are addressed.
|
4644 |
|
|
|
4645 |
|
|
The BusLogic Driver Debugging Options comprise the following:
|
4646 |
|
|
|
4647 |
|
|
TraceProbe
|
4648 |
|
|
|
4649 |
|
|
The "TraceProbe" option enables tracing of Host Adapter Probing.
|
4650 |
|
|
|
4651 |
|
|
TraceHardwareReset
|
4652 |
|
|
|
4653 |
|
|
The "TraceHardwareReset" option enables tracing of Host Adapter Hardware
|
4654 |
|
|
Reset.
|
4655 |
|
|
|
4656 |
|
|
TraceConfiguration
|
4657 |
|
|
|
4658 |
|
|
The "TraceConfiguration" option enables tracing of Host Adapter
|
4659 |
|
|
Configuration.
|
4660 |
|
|
|
4661 |
|
|
TraceErrors
|
4662 |
|
|
|
4663 |
|
|
The "TraceErrors" option enables tracing of SCSI Commands that return an
|
4664 |
|
|
error from the Target Device. The CDB and Sense Data will be printed for
|
4665 |
|
|
each SCSI Command that fails.
|
4666 |
|
|
|
4667 |
|
|
Debug
|
4668 |
|
|
|
4669 |
|
|
The "Debug" option enables all debugging options.
|
4670 |
|
|
|
4671 |
|
|
The following examples demonstrate setting the Queue Depth for Target Devices
|
4672 |
