212	  can enable logging by saying Y to "/proc file system support" and
213	  "Sysctl support" below and executing the command
214

218	  and logging level for each type of logging selected.
219
220	  There are a number of logging types and you can find them in the
221	  source at <file:drivers/scsi/scsi_logging.h>. The logging levels
222	  are also described in that file and they determine the verbosity of
223	  the logging for each logging type.
224
225	  If you say N here, it may be harder to track down some types of SCSI
226	  problems. If you say Y here your kernel will be somewhat larger, but

1017	  "Tagged command queuing" is a feature of SCSI-2 which improves
1018	  performance: the host adapter can send several SCSI commands to a
1019	  device's queue even if previous commands haven't finished yet.
1020	  Because the device is intelligent, it can optimize its operations
1021	  (like head positioning) based on its own request queue. Some SCSI
1022	  devices don't implement this properly; if you want to disable this
1023	  feature, enter 0 or 1 here (it doesn't matter which).
1024
1025	  The default value is 8 and should be supported by most hard disks.
1026	  This value can be overridden from the boot command line using the
1027	  'tags' option as follows (example):
1028	  'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1029	  4, set queue depth to 16 for target 2 and target 3 on controller 0
1030	  and set queue depth to 10 for target 0 / lun 2 on controller 1.
1031
1032	  The normal answer therefore is to go with the default 8 and to use
1033	  a boot command line option for devices that need to use a different
1034	  command queue depth.

1043	  This option allows you to specify the maximum number of commands
1044	  that can be queued to any device, when tagged command queuing is
1045	  possible. The default value is 32. Minimum is 2, maximum is 64.
1046	  Modern hard disks are able to support 64 tags and even more, but
1047	  do not seem to be faster when more than 32 tags are being used.
1048
1049	  So, the normal answer here is to go with the default value 32 unless
1050	  you are using very large hard disks with large cache (>= 1 MB) that
1051	  are able to take advantage of more than 32 tagged commands.
1052
1053	  There is no safe option and the default answer is recommended.

1057	depends on SCSI_ZALON
1058	default "20"
1059	help
1060	  The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1061	  rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80.  The numbers
1062	  are respectively the maximum data transfer rates in mega-transfers
1063	  per second for each class.  For example, a FAST-20 Wide 16 device is
1064	  able to transfer data at 20 million 16 bit packets per second for a
1065	  total rate of 40 MB/s.
1066
1067	  You may specify 0 if you want to only use asynchronous data
1068	  transfers. This is the safest and slowest option. Otherwise, specify
1069	  a value between 5 and 80, depending on the capability of your SCSI
1070	  controller.  The higher the number, the faster the data transfer.
1071	  Note that 80 should normally be ok since the driver decreases the
1072	  value automatically according to the controller's capabilities.
1073
1074	  Your answer to this question is ignored for controllers with NVRAM,
1075	  since the driver will get this information from the user set-up.  It
1076	  also can be overridden using a boot setup option, as follows
1077	  (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1078	  for FAST-20 synchronous data transfer (20 mega-transfers per
1079	  second).
1080
1081	  The normal answer therefore is not to go with the default but to
1082	  select the maximum value 80 allowing the driver to use the maximum
1083	  value supported by each controller. If this causes problems with
1084	  your SCSI devices, you should come back and decrease the value.
1085
1086	  There is no safe option other than using good cabling, right
1087	  terminations and SCSI conformant devices.
