19	  because you will be asked for it.
20
21	  You also need to say Y here if you have a device which speaks
22	  the SCSI protocol.  Examples of this include the parallel port

147	  If you want to use SCSI scanners, synthesizers or CD-writers or just
148	  about anything having "SCSI" in its name other than hard disks,
149	  CD-ROMs or tapes, say Y here. These won't be supported by the kernel
150	  directly, so you need some additional software which knows how to
151	  talk to these devices using the SCSI protocol:
152
153	  For scanners, look at SANE (<http://www.mostang.com/sane/>). For CD
154	  writer software look at Cdrtools
155	  (<http://www.fokus.gmd.de/research/cc/glone/employees/joerg.schilling/private/cdrecord.html>)
156	  and for burning a "disk at once": CDRDAO
157	  (<http://cdrdao.sourceforge.net/>). Cdparanoia is a high
158	  quality digital reader of audio CDs (<http://www.xiph.org/paranoia/>).
159	  For other devices, it's possible that you'll have to write the
160	  driver software yourself. Please read the file

176	  If you have such hardware and want to use it with linux, say Y
177	  here.  Check <file:Documentation/scsi/scsi-changer.txt> for details.
178
179	  If you want to compile this as a module ( = code which can be
180	  inserted in and removed from the running kernel whenever you want),

198	  Some devices support more than one LUN (Logical Unit Number) in order
199	  to allow access to several media, e.g. CD jukebox, USB card reader,
200	  mobile phone in mass storage mode. This option forces the kernel to
201	  probe for all LUNs by default. This setting can be overriden by
202	  max_luns boot/module parameter. Note that this option does not affect
203	  devices conforming to SCSI-3 or higher as they can explicitely report
204	  their number of LUNs. It is safe to say Y here unless you have one of
205	  those rare devices which reacts in an unexpected way when probed for
206	  multiple LUNs.
207
208config SCSI_CONSTANTS

216config SCSI_LOGGING

218	depends on SCSI
219	---help---
220	  This turns on a logging facility that can be used to debug a number
221	  of SCSI related problems.
222
223	  If you say Y here, no logging output will appear by default, but you
224	  can enable logging by saying Y to "/proc file system support" and
225	  "Sysctl support" below and executing the command
226
227	  echo <bitmask> > /proc/sys/dev/scsi/logging_level
228
229	  where <bitmask> is a four byte value representing the logging type
230	  and logging level for each type of logging selected.
231
232	  There are a number of logging types and you can find them in the
233	  source at <file:drivers/scsi/scsi_logging.h>. The logging levels
234	  are also described in that file and they determine the verbosity of
235	  the logging for each logging type.
236
237	  If you say N here, it may be harder to track down some types of SCSI
238	  problems. If you say Y here your kernel will be somewhat larger, but
239	  there should be no noticeable performance impact as long as you have
240	  logging turned off.
241
242config SCSI_SCAN_ASYNC
243	bool "Asynchronous SCSI scanning"
244	depends on SCSI
245	help
246	  The SCSI subsystem can probe for devices while the rest of the
247	  system continues booting, and even probe devices on different
248	  busses in parallel, leading to a significant speed-up.
249
250	  If you have built SCSI as modules, enabling this option can
251	  be a problem as the devices may not have been found by the
252	  time your system expects them to have been.  You can load the
253	  scsi_wait_scan module to ensure that all scans have completed.
254	  If you build your SCSI drivers into the kernel, then everything
255	  will work fine if you say Y here.
256
257	  You can override this choice by specifying "scsi_mod.scan=sync"
258	  or async on the kernel's command line.

264	depends on MODULES
265# scsi_wait_scan is a loadable module which waits until all the async scans are
266# complete.  The idea is to use it in initrd/ initramfs scripts.  You modprobe
267# it after all the modprobes of the root SCSI drivers and it will wait until
268# they have all finished scanning their buses before allowing the boot to
269# proceed.  (This method is not applicable if targets boot independently in
270# parallel with the initiator, or with transports with non-deterministic target
271# discovery schemes, or if a transport driver does not support scsi_wait_scan.)
272#
273# This symbol is not exposed as a prompt because little is to be gained by
274# disabling it, whereas people who accidentally switch it off may wonder why
275# their mkinitrd gets into trouble.

512	  chip from the aic777x series or the aic78xx series, this driver
513	  should work. The only exception is the 7810 which is specifically
514	  not supported (that's the RAID controller chip on the AAA-13x
515	  cards).
516
517	  Note that the AHA2920 SCSI host adapter is *not* supported by this
518	  driver; choose "Future Domain 16xx SCSI support" instead if you have
519	  one of those.
520
521	  Information on the configuration options for this controller can be

525	  contacting the maintainer with any questions.  The SCSI-HOWTO,

876	bool "Standard SCSI-order"
877	depends on SCSI_IBMMCA
878	---help---
879	  In the PC-world and in most modern SCSI-BIOS-setups, SCSI-hard disks
880	  are assigned to the drive letters, starting with the lowest SCSI-id
881	  (physical number -- pun) to be drive C:, as seen from DOS and
882	  similar operating systems. When looking into papers describing the
883	  ANSI-SCSI-standard, this assignment of drives appears to be wrong.
884	  The SCSI-standard follows a hardware-hierarchy which says that id 7
885	  has the highest priority and id 0 the lowest. Therefore, the host
886	  adapters are still today everywhere placed as SCSI-id 7 by default.
887	  In the SCSI-standard, the drive letters express the priority of the
888	  disk. C: should be the hard disk, or a partition on it, with the
889	  highest priority. This must therefore be the disk with the highest
890	  SCSI-id (e.g. 6) and not the one with the lowest! IBM-BIOS kept the
891	  original definition of the SCSI-standard as also industrial- and
892	  process-control-machines, like VME-CPUs running under realtime-OSes
893	  (e.g. LynxOS, OS9) do.
894
895	  If you like to run Linux on your MCA-machine with the same
896	  assignment of hard disks as seen from e.g. DOS or OS/2 on your
897	  machine, which is in addition conformant to the SCSI-standard, you
898	  must say Y here. This is also necessary for MCA-Linux users who want
899	  to keep downward compatibility to older releases of the
900	  IBM-MCA-SCSI-driver (older than driver-release 2.00 and older than
901	  June 1997).
902
903	  If you like to have the lowest SCSI-id assigned as drive C:, as
904	  modern SCSI-BIOSes do, which does not conform to the standard, but
905	  is widespread and common in the PC-world of today, you must say N
906	  here. If unsure, say Y.

913	  However, some devices exist, like special-control-devices,
914	  SCSI-CNC-machines, SCSI-printer or scanners of older type, that do
915	  not reset when switched on. If you say Y here, each device connected
916	  to your SCSI-bus will be issued a reset-command after it has been
917	  probed, while the kernel is booting. This may cause problems with
918	  more modern devices, like hard disks, which do not appreciate these
919	  reset commands, and can cause your system to hang. So say Y only if

1269	default "8"
1270	---help---
1271	  "Tagged command queuing" is a feature of SCSI-2 which improves
1272	  performance: the host adapter can send several SCSI commands to a
1273	  device's queue even if previous commands haven't finished yet.
1274	  Because the device is intelligent, it can optimize its operations
1275	  (like head positioning) based on its own request queue. Some SCSI
1276	  devices don't implement this properly; if you want to disable this
1277	  feature, enter 0 or 1 here (it doesn't matter which).
1278
1279	  The default value is 8 and should be supported by most hard disks.
1280	  This value can be overridden from the boot command line using the
1281	  'tags' option as follows (example):
1282	  'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1283	  4, set queue depth to 16 for target 2 and target 3 on controller 0
1284	  and set queue depth to 10 for target 0 / lun 2 on controller 1.
1285
1286	  The normal answer therefore is to go with the default 8 and to use
1287	  a boot command line option for devices that need to use a different
1288	  command queue depth.
1289
1290	  There is no safe option other than using good SCSI devices.

1300	  Modern hard disks are able to support 64 tags and even more, but
1301	  do not seem to be faster when more than 32 tags are being used.
1302
1303	  So, the normal answer here is to go with the default value 32 unless
1304	  you are using very large hard disks with large cache (>= 1 MB) that
1305	  are able to take advantage of more than 32 tagged commands.
1306

1314	  The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1315	  rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80.  The numbers
1316	  are respectively the maximum data transfer rates in mega-transfers
1317	  per second for each class.  For example, a FAST-20 Wide 16 device is
1318	  able to transfer data at 20 million 16 bit packets per second for a
1319	  total rate of 40 MB/s.
1320
1321	  You may specify 0 if you want to only use asynchronous data
1322	  transfers. This is the safest and slowest option. Otherwise, specify
1323	  a value between 5 and 80, depending on the capability of your SCSI
1324	  controller.  The higher the number, the faster the data transfer.
1325	  Note that 80 should normally be ok since the driver decreases the
1326	  value automatically according to the controller's capabilities.
1327
1328	  Your answer to this question is ignored for controllers with NVRAM,
1329	  since the driver will get this information from the user set-up.  It
1330	  also can be overridden using a boot setup option, as follows
1331	  (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1332	  for FAST-20 synchronous data transfer (20 mega-transfers per
1333	  second).
1334
1335	  The normal answer therefore is not to go with the default but to
1336	  select the maximum value 80 allowing the driver to use the maximum
1337	  value supported by each controller. If this causes problems with
1338	  your SCSI devices, you should come back and decrease the value.
