194	  There are a number of logging types and you can find them in the
195	  source at <file:drivers/scsi/scsi_logging.h>. The logging levels
196	  are also described in that file and they determine the verbosity of
197	  the logging for each logging type.
198
199	  If you say N here, it may be harder to track down some types of SCSI

1013	  "Tagged command queuing" is a feature of SCSI-2 which improves
1014	  performance: the host adapter can send several SCSI commands to a
1015	  device's queue even if previous commands haven't finished yet.
1016	  Because the device is intelligent, it can optimize its operations
1017	  (like head positioning) based on its own request queue. Some SCSI
1018	  devices don't implement this properly; if you want to disable this
1019	  feature, enter 0 or 1 here (it doesn't matter which).
1020
1021	  The default value is 8 and should be supported by most hard disks.
1022	  This value can be overridden from the boot command line using the
1023	  'tags' option as follows (example):
1024	  'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to

1026	  and set queue depth to 10 for target 0 / lun 2 on controller 1.

1039	  This option allows you to specify the maximum number of commands
1040	  that can be queued to any device, when tagged command queuing is
1041	  possible. The default value is 32. Minimum is 2, maximum is 64.
1042	  Modern hard disks are able to support 64 tags and even more, but
1043	  do not seem to be faster when more than 32 tags are being used.
1044
1045	  So, the normal answer here is to go with the default value 32 unless
1046	  you are using very large hard disks with large cache (>= 1 MB) that
1047	  are able to take advantage of more than 32 tagged commands.
1048
1049	  There is no safe option and the default answer is recommended.

1054	default "20"
1055	help
1056	  The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1057	  rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80.  The numbers
1058	  are respectively the maximum data transfer rates in mega-transfers
1059	  per second for each class.  For example, a FAST-20 Wide 16 device is
1060	  able to transfer data at 20 million 16 bit packets per second for a
1061	  total rate of 40 MB/s.
1062
1063	  You may specify 0 if you want to only use asynchronous data
1064	  transfers. This is the safest and slowest option. Otherwise, specify
1065	  a value between 5 and 80, depending on the capability of your SCSI
1066	  controller.  The higher the number, the faster the data transfer.
1067	  Note that 80 should normally be ok since the driver decreases the
1068	  value automatically according to the controller's capabilities.
1069
1070	  Your answer to this question is ignored for controllers with NVRAM,
1071	  since the driver will get this information from the user set-up.  It
1072	  also can be overridden using a boot setup option, as follows
1073	  (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1074	  for FAST-20 synchronous data transfer (20 mega-transfers per
1075	  second).
1076
1077	  The normal answer therefore is not to go with the default but to
1078	  select the maximum value 80 allowing the driver to use the maximum
1079	  value supported by each controller. If this causes problems with
1080	  your SCSI devices, you should come back and decrease the value.
1081
1082	  There is no safe option other than using good cabling, right
1083	  terminations and SCSI conformant devices.
