21 If you want to use a SCSI hard disk, SCSI tape drive, SCSI CD-ROM or
22 any other SCSI device under Linux, say Y and make sure that you know
23 the name of your SCSI host adapter (the card inside your computer
24 that "speaks" the SCSI protocol, also called SCSI controller),
25 because you will be asked for it.
26
27 You also need to say Y here if you have a device which speaks
28 the SCSI protocol. Examples of this include the parallel port
29 version of the IOMEGA ZIP drive, USB storage devices, Fibre
30 Channel, and FireWire storage.

157 about anything having "SCSI" in its name other than hard disks,
158 CD-ROMs or tapes, say Y here. These won't be supported by the kernel
159 directly, so you need some additional software which knows how to
160 talk to these devices using the SCSI protocol:
161
162 For scanners, look at SANE (<http://www.sane-project.org/>). For CD
163 writer software look at Cdrtools
164 (<http://cdrecord.berlios.de/private/cdrecord.html>)
165 and for burning a "disk at once": CDRDAO
166 (<http://cdrdao.sourceforge.net/>). Cdparanoia is a high
167 quality digital reader of audio CDs (<http://www.xiph.org/paranoia/>).
168 For other devices, it's possible that you'll have to write the

216 This turns on a logging facility that can be used to debug a number
217 of SCSI related problems.
218
219 If you say Y here, no logging output will appear by default, but you
220 can enable logging by saying Y to "/proc file system support" and
221 "Sysctl support" below and executing the command
222
223 echo <bitmask> > /proc/sys/dev/scsi/logging_level
224
225 where <bitmask> is a four byte value representing the logging type
226 and logging level for each type of logging selected.
227
228 There are a number of logging types and you can find them in the
229 source at <file:drivers/scsi/scsi_logging.h>. The logging levels
230 are also described in that file and they determine the verbosity of
231 the logging for each logging type.
232
233 If you say N here, it may be harder to track down some types of SCSI
234 problems. If you say Y here your kernel will be somewhat larger, but
235 there should be no noticeable performance impact as long as you have

1158 int "default tagged command queue depth"
1159 depends on SCSI_ZALON || SCSI_NCR_Q720
1160 default "8"
1161 ---help---
1162 "Tagged command queuing" is a feature of SCSI-2 which improves
1163 performance: the host adapter can send several SCSI commands to a
1164 device's queue even if previous commands haven't finished yet.
1165 Because the device is intelligent, it can optimize its operations
1166 (like head positioning) based on its own request queue. Some SCSI
1167 devices don't implement this properly; if you want to disable this
1168 feature, enter 0 or 1 here (it doesn't matter which).
1169
1170 The default value is 8 and should be supported by most hard disks.
1171 This value can be overridden from the boot command line using the
1172 'tags' option as follows (example):
1173 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1174 4, set queue depth to 16 for target 2 and target 3 on controller 0
1175 and set queue depth to 10 for target 0 / lun 2 on controller 1.
1176
1177 The normal answer therefore is to go with the default 8 and to use
1178 a boot command line option for devices that need to use a different
1179 command queue depth.
1180
1181 There is no safe option other than using good SCSI devices.

1188 This option allows you to specify the maximum number of commands
1189 that can be queued to any device, when tagged command queuing is
1190 possible. The default value is 32. Minimum is 2, maximum is 64.
1191 Modern hard disks are able to support 64 tags and even more, but
1192 do not seem to be faster when more than 32 tags are being used.
1193
1194 So, the normal answer here is to go with the default value 32 unless
1195 you are using very large hard disks with large cache (>= 1 MB) that
1196 are able to take advantage of more than 32 tagged commands.
1197
1198 There is no safe option and the default answer is recommended.

1204 ---help---
1205 The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1206 rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80. The numbers
1207 are respectively the maximum data transfer rates in mega-transfers
1208 per second for each class. For example, a FAST-20 Wide 16 device is
1209 able to transfer data at 20 million 16 bit packets per second for a
1210 total rate of 40 MB/s.
1211
1212 You may specify 0 if you want to only use asynchronous data
1213 transfers. This is the safest and slowest option. Otherwise, specify
1214 a value between 5 and 80, depending on the capability of your SCSI
1215 controller. The higher the number, the faster the data transfer.
1216 Note that 80 should normally be ok since the driver decreases the
1217 value automatically according to the controller's capabilities.
1218
1219 Your answer to this question is ignored for controllers with NVRAM,
1220 since the driver will get this information from the user set-up. It
1221 also can be overridden using a boot setup option, as follows
1222 (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1223 for FAST-20 synchronous data transfer (20 mega-transfers per
1224 second).
1225
1226 The normal answer therefore is not to go with the default but to
1227 select the maximum value 80 allowing the driver to use the maximum
1228 value supported by each controller. If this causes problems with
1229 your SCSI devices, you should come back and decrease the value.
1230
1231 There is no safe option other than using good cabling, right
1232 terminations and SCSI conformant devices.

1240 feature. In that case, you would say Y here. In general however, to

1242 than 1 device on a SCSI bus. The normal answer therefore is N.
