1156	default "8"
1157	---help---
1158	  "Tagged command queuing" is a feature of SCSI-2 which improves
1159	  performance: the host adapter can send several SCSI commands to a
1160	  device's queue even if previous commands haven't finished yet.
1161	  Because the device is intelligent, it can optimize its operations
1162	  (like head positioning) based on its own request queue. Some SCSI
1163	  devices don't implement this properly; if you want to disable this
1164	  feature, enter 0 or 1 here (it doesn't matter which).
1165
1166	  The default value is 8 and should be supported by most hard disks.
1167	  This value can be overridden from the boot command line using the
1168	  'tags' option as follows (example):
1169	  'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1170	  4, set queue depth to 16 for target 2 and target 3 on controller 0
1171	  and set queue depth to 10 for target 0 / lun 2 on controller 1.
1172
1173	  The normal answer therefore is to go with the default 8 and to use
1174	  a boot command line option for devices that need to use a different
1175	  command queue depth.
1176
1177	  There is no safe option other than using good SCSI devices.

1183	---help---
1184	  This option allows you to specify the maximum number of commands
1185	  that can be queued to any device, when tagged command queuing is
1186	  possible. The default value is 32. Minimum is 2, maximum is 64.
1187	  Modern hard disks are able to support 64 tags and even more, but
1188	  do not seem to be faster when more than 32 tags are being used.
1189
1190	  So, the normal answer here is to go with the default value 32 unless
1191	  you are using very large hard disks with large cache (>= 1 MB) that
1192	  are able to take advantage of more than 32 tagged commands.
1193

1198	depends on SCSI_ZALON || SCSI_NCR_Q720
1199	default "20"
1200	---help---
1201	  The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1202	  rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80.  The numbers
1203	  are respectively the maximum data transfer rates in mega-transfers
1204	  per second for each class.  For example, a FAST-20 Wide 16 device is
1205	  able to transfer data at 20 million 16 bit packets per second for a
1206	  total rate of 40 MB/s.
1207
1208	  You may specify 0 if you want to only use asynchronous data
1209	  transfers. This is the safest and slowest option. Otherwise, specify
1210	  a value between 5 and 80, depending on the capability of your SCSI
1211	  controller.  The higher the number, the faster the data transfer.
1212	  Note that 80 should normally be ok since the driver decreases the
1213	  value automatically according to the controller's capabilities.
1214
1215	  Your answer to this question is ignored for controllers with NVRAM,
1216	  since the driver will get this information from the user set-up.  It
1217	  also can be overridden using a boot setup option, as follows
1218	  (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1219	  for FAST-20 synchronous data transfer (20 mega-transfers per
1220	  second).
1221
1222	  The normal answer therefore is not to go with the default but to
1223	  select the maximum value 80 allowing the driver to use the maximum
1224	  value supported by each controller. If this causes problems with
1225	  your SCSI devices, you should come back and decrease the value.
1226
1227	  There is no safe option other than using good cabling, right
1228	  terminations and SCSI conformant devices.

1234	  This option is only provided for safety if you suspect some SCSI
1235	  device of yours to not support properly the target-disconnect

1237	  not allow targets to disconnect is not reasonable if there is more
