201	  If you say Y here, no logging output will appear by default, but you
202	  can enable logging by saying Y to "/proc file system support" and
203	  "Sysctl support" below and executing the command
204
205	  echo <bitmask> > /proc/sys/dev/scsi/logging_level

208	  and logging level for each type of logging selected.
209
210	  There are a number of logging types and you can find them in the
211	  source at <file:drivers/scsi/scsi_logging.h>. The logging levels
212	  are also described in that file and they determine the verbosity of
213	  the logging for each logging type.
214
215	  If you say N here, it may be harder to track down some types of SCSI
216	  problems. If you say Y here your kernel will be somewhat larger, but
217	  there should be no noticeable performance impact as long as you have

1043
1044	  The normal answer therefore is to go with the default 8 and to use

1046	  command queue depth.

1055	  This option allows you to specify the maximum number of commands

1059	  do not seem to be faster when more than 32 tags are being used.
1060
1061	  So, the normal answer here is to go with the default value 32 unless
1062	  you are using very large hard disks with large cache (>= 1 MB) that

1071	help
1072	  The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1073	  rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80.  The numbers
1074	  are respectively the maximum data transfer rates in mega-transfers
1075	  per second for each class.  For example, a FAST-20 Wide 16 device is
1076	  able to transfer data at 20 million 16 bit packets per second for a
1077	  total rate of 40 MB/s.
1078
1079	  You may specify 0 if you want to only use asynchronous data
1080	  transfers. This is the safest and slowest option. Otherwise, specify
1081	  a value between 5 and 80, depending on the capability of your SCSI
1082	  controller.  The higher the number, the faster the data transfer.
1083	  Note that 80 should normally be ok since the driver decreases the
1084	  value automatically according to the controller's capabilities.
1085
1086	  Your answer to this question is ignored for controllers with NVRAM,
1087	  since the driver will get this information from the user set-up.  It
1088	  also can be overridden using a boot setup option, as follows
1089	  (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1090	  for FAST-20 synchronous data transfer (20 mega-transfers per
1091	  second).
1092
1093	  The normal answer therefore is not to go with the default but to
1094	  select the maximum value 80 allowing the driver to use the maximum
1095	  value supported by each controller. If this causes problems with
1096	  your SCSI devices, you should come back and decrease the value.
1097
1098	  There is no safe option other than using good cabling, right
1099	  terminations and SCSI conformant devices.
