155	  directly, so you need some additional software which knows how to
156	  talk to these devices using the SCSI protocol:
157
158	  For scanners, look at SANE (<http://www.sane-project.org/>). For CD
159	  writer software look at Cdrtools
160	  (<http://cdrecord.berlios.de/private/cdrecord.html>)
161	  and for burning a "disk at once": CDRDAO

164	  For other devices, it's possible that you'll have to write the

216	  can enable logging by saying Y to "/proc file system support" and
217	  "Sysctl support" below and executing the command
218
219	  echo <bitmask> > /proc/sys/dev/scsi/logging_level

222	  and logging level for each type of logging selected.
223
224	  There are a number of logging types and you can find them in the
225	  source at <file:drivers/scsi/scsi_logging.h>. The logging levels
226	  are also described in that file and they determine the verbosity of
227	  the logging for each logging type.
228
229	  If you say N here, it may be harder to track down some types of SCSI

1033	  and set queue depth to 10 for target 0 / lun 2 on controller 1.
1034
1035	  The normal answer therefore is to go with the default 8 and to use
1036	  a boot command line option for devices that need to use a different
1037	  command queue depth.
1038

1046	  This option allows you to specify the maximum number of commands
1047	  that can be queued to any device, when tagged command queuing is
1048	  possible. The default value is 32. Minimum is 2, maximum is 64.
1049	  Modern hard disks are able to support 64 tags and even more, but
1050	  do not seem to be faster when more than 32 tags are being used.
1051
1052	  So, the normal answer here is to go with the default value 32 unless
1053	  you are using very large hard disks with large cache (>= 1 MB) that
1054	  are able to take advantage of more than 32 tagged commands.
1055

1062	---help---
1063	  The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1064	  rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80.  The numbers
1065	  are respectively the maximum data transfer rates in mega-transfers
1066	  per second for each class.  For example, a FAST-20 Wide 16 device is
1067	  able to transfer data at 20 million 16 bit packets per second for a
1068	  total rate of 40 MB/s.
1069
1070	  You may specify 0 if you want to only use asynchronous data
1071	  transfers. This is the safest and slowest option. Otherwise, specify
1072	  a value between 5 and 80, depending on the capability of your SCSI
1073	  controller.  The higher the number, the faster the data transfer.
1074	  Note that 80 should normally be ok since the driver decreases the
1075	  value automatically according to the controller's capabilities.
1076
1077	  Your answer to this question is ignored for controllers with NVRAM,
1078	  since the driver will get this information from the user set-up.  It
1079	  also can be overridden using a boot setup option, as follows
1080	  (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1081	  for FAST-20 synchronous data transfer (20 mega-transfers per
1082	  second).
1083
1084	  The normal answer therefore is not to go with the default but to
1085	  select the maximum value 80 allowing the driver to use the maximum
1086	  value supported by each controller. If this causes problems with
1087	  your SCSI devices, you should come back and decrease the value.
1088
1089	  There is no safe option other than using good cabling, right
1090	  terminations and SCSI conformant devices.
