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

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

186	  don't need this for those tiny 6-slot cdrom changers.  Media
187	  changers are listed as "Type: Medium Changer" in /proc/scsi/scsi.
188	  If you have such hardware and want to use it with linux, say Y
189	  here.  Check <file:Documentation/scsi/scsi-changer.txt> for details.
190
191	  If you want to compile this as a module ( = code which can be
192	  inserted in and removed from the running kernel whenever you want),
193	  say M here and read <file:Documentation/kbuild/modules.txt> and

204	  it has an enclosure device.  Selecting this option will just allow

215config SCSI_LOGGING

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

245	  The SCSI subsystem can probe for devices while the rest of the
246	  system continues booting, and even probe devices on different
247	  busses in parallel, leading to a significant speed-up.
248
249	  You can override this choice by specifying "scsi_mod.scan=sync"
250	  or async on the kernel's command line.

1111	default "8"
1112	---help---
1113	  "Tagged command queuing" is a feature of SCSI-2 which improves
1114	  performance: the host adapter can send several SCSI commands to a
1115	  device's queue even if previous commands haven't finished yet.
1116	  Because the device is intelligent, it can optimize its operations
1117	  (like head positioning) based on its own request queue. Some SCSI
1118	  devices don't implement this properly; if you want to disable this
1119	  feature, enter 0 or 1 here (it doesn't matter which).
1120
1121	  The default value is 8 and should be supported by most hard disks.
1122	  This value can be overridden from the boot command line using the
1123	  'tags' option as follows (example):
1124	  'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1125	  4, set queue depth to 16 for target 2 and target 3 on controller 0
1126	  and set queue depth to 10 for target 0 / lun 2 on controller 1.
1127
1128	  The normal answer therefore is to go with the default 8 and to use
1129	  a boot command line option for devices that need to use a different
1130	  command queue depth.
1131
1132	  There is no safe option other than using good SCSI devices.

1142	  Modern hard disks are able to support 64 tags and even more, but
1143	  do not seem to be faster when more than 32 tags are being used.
1144
1145	  So, the normal answer here is to go with the default value 32 unless
1146	  you are using very large hard disks with large cache (>= 1 MB) that
1147	  are able to take advantage of more than 32 tagged commands.
1148

1155	---help---
1156	  The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1157	  rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80.  The numbers
1158	  are respectively the maximum data transfer rates in mega-transfers
1159	  per second for each class.  For example, a FAST-20 Wide 16 device is
1160	  able to transfer data at 20 million 16 bit packets per second for a
1161	  total rate of 40 MB/s.
1162
1163	  You may specify 0 if you want to only use asynchronous data
1164	  transfers. This is the safest and slowest option. Otherwise, specify
1165	  a value between 5 and 80, depending on the capability of your SCSI
1166	  controller.  The higher the number, the faster the data transfer.
1167	  Note that 80 should normally be ok since the driver decreases the
1168	  value automatically according to the controller's capabilities.
1169
1170	  Your answer to this question is ignored for controllers with NVRAM,
1171	  since the driver will get this information from the user set-up.  It
1172	  also can be overridden using a boot setup option, as follows
1173	  (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1174	  for FAST-20 synchronous data transfer (20 mega-transfers per
1175	  second).
1176
1177	  The normal answer therefore is not to go with the default but to
1178	  select the maximum value 80 allowing the driver to use the maximum
1179	  value supported by each controller. If this causes problems with
1180	  your SCSI devices, you should come back and decrease the value.
