137	  CD-ROMs or tapes, say Y here. These won't be supported by the kernel
138	  directly, so you need some additional software which knows how to
139	  talk to these devices using the SCSI protocol:
140

142	  writer software look at Cdrtools
143	  (<http://cdrtools.sourceforge.net/>)
144	  and for burning a "disk at once": CDRDAO
145	  (<http://cdrdao.sourceforge.net/>). Cdparanoia is a high

210	  If you say Y here, no logging output will appear by default, but you
211	  can enable logging by saying Y to "/proc file system support" and
212	  "Sysctl support" below and executing the command
213
214	  echo <bitmask> > /proc/sys/dev/scsi/logging_level
215
216	  where <bitmask> is a four byte value representing the logging type
217	  and logging level for each type of logging selected.
218
219	  There are a number of logging types and you can find them in the
220	  source at <file:drivers/scsi/scsi_logging.h>. The logging levels
221	  are also described in that file and they determine the verbosity of
222	  the logging for each logging type.
223
224	  If you say N here, it may be harder to track down some types of SCSI
225	  problems. If you say Y here your kernel will be somewhat larger, but
226	  there should be no noticeable performance impact as long as you have

1016	  "Tagged command queuing" is a feature of SCSI-2 which improves
1017	  performance: the host adapter can send several SCSI commands to a
1018	  device's queue even if previous commands haven't finished yet.
1019	  Because the device is intelligent, it can optimize its operations
1020	  (like head positioning) based on its own request queue. Some SCSI
1021	  devices don't implement this properly; if you want to disable this
1022	  feature, enter 0 or 1 here (it doesn't matter which).
1023
1024	  The default value is 8 and should be supported by most hard disks.
1025	  This value can be overridden from the boot command line using the
1026	  'tags' option as follows (example):
1027	  'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to

1029	  and set queue depth to 10 for target 0 / lun 2 on controller 1.
1030
1031	  The normal answer therefore is to go with the default 8 and to use

1043	  that can be queued to any device, when tagged command queuing is
1044	  possible. The default value is 32. Minimum is 2, maximum is 64.
1045	  Modern hard disks are able to support 64 tags and even more, but
1046	  do not seem to be faster when more than 32 tags are being used.
1047
1048	  So, the normal answer here is to go with the default value 32 unless
1049	  you are using very large hard disks with large cache (>= 1 MB) that
1050	  are able to take advantage of more than 32 tagged commands.
1051

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