19 select SCSI_DMA if HAS_DMA
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.
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.
32 To compile this driver as a module, choose M here and read
33 <file:Documentation/scsi/scsi.txt>.
34 The module will be called scsi_mod.
36 However, do not compile this as a module if your root file system
37 (the one containing the directory /) is located on a SCSI device.
48 config SCSI_MQ_DEFAULT
49 bool "SCSI: use blk-mq I/O path by default"
52 This option enables the new blk-mq based I/O path for SCSI
53 devices by default. With the option the scsi_mod.use_blk_mq
54 module/boot option defaults to Y, without it to N, but it can
55 still be overridden either way.
60 bool "legacy /proc/scsi/ support"
61 depends on SCSI && PROC_FS
64 This option enables support for the various files in
65 /proc/scsi. In Linux 2.6 this has been superseded by
66 files in sysfs but many legacy applications rely on this.

77 If you want to use SCSI hard disks, Fibre Channel disks,
78 Serial ATA (SATA) or Parallel ATA (PATA) hard disks,
79 USB storage or the SCSI or parallel port version of
80 the IOMEGA ZIP drive, say Y and read the SCSI-HOWTO,

91 In this case, do not compile the driver for your SCSI host adapter
92 (below) as a module either.
95 tristate "SCSI tape support"
98 If you want to use a SCSI tape drive under Linux, say Y and read the

108 tristate "SCSI OnStream SC-x0 tape support"
111 The OnStream SC-x0 SCSI tape drives cannot be driven by the
112 standard st driver, but instead need this special osst driver and
113 use the /dev/osstX char device nodes (major 206). Via usb-storage,
114 you may be able to drive the USB-x0 and DI-x0 drives as well.
115 Note that there is also a second generation of OnStream
116 tape drives (ADR-x0) that supports the standard SCSI-2 commands for
117 tapes (QIC-157) and can be driven by the standard driver st.
118 For more information, you may have a look at the SCSI-HOWTO
119 <http://www.tldp.org/docs.html#howto> and
120 <file:Documentation/scsi/osst.txt> in the kernel source.
121 More info on the OnStream driver may be found on
122 <http://sourceforge.net/projects/osst/>
123 Please also have a look at the standard st docu, as most of it
124 applies to osst as well.
126 To compile this driver as a module, choose M here and read
127 <file:Documentation/scsi/scsi.txt>. The module will be called osst.
130 tristate "SCSI CDROM support"
133 If you want to use a CD or DVD drive attached to your computer
134 by SCSI, FireWire, USB or ATAPI, say Y and read the SCSI-HOWTO
135 and the CDROM-HOWTO at <http://www.tldp.org/docs.html#howto>.
137 Make sure to say Y or M to "ISO 9660 CD-ROM file system support".

144 bool "Enable vendor-specific extensions (for SCSI CDROM)"
145 depends on BLK_DEV_SR
147 This enables the usage of vendor specific SCSI commands. This is
148 required to support multisession CDs with old NEC/TOSHIBA cdrom
149 drives (and HP Writers). If you have such a drive and get the first
150 session only, try saying Y here; everybody else says N.
153 tristate "SCSI generic support"
156 If you want to use SCSI scanners, synthesizers or CD-writers or just
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:
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
169 driver software yourself. Please read the file
170 <file:Documentation/scsi/scsi-generic.txt> for more information.
172 To compile this driver as a module, choose M here and read
173 <file:Documentation/scsi/scsi.txt>. The module will be called sg.
178 tristate "SCSI media changer support"
181 This is a driver for SCSI media changers. Most common devices are
182 tape libraries and MOD/CDROM jukeboxes. *Real* jukeboxes, you
183 don't need this for those tiny 6-slot cdrom changers. Media
184 changers are listed as "Type: Medium Changer" in /proc/scsi/scsi.
185 If you have such hardware and want to use it with linux, say Y
186 here. Check <file:Documentation/scsi/scsi-changer.txt> for details.
188 If you want to compile this as a module ( = code which can be
189 inserted in and removed from the running kernel whenever you want),
190 say M here and read <file:Documentation/kbuild/modules.txt> and
191 <file:Documentation/scsi/scsi.txt>. The module will be called ch.o.
194 config SCSI_ENCLOSURE
195 tristate "SCSI Enclosure Support"
196 depends on SCSI && ENCLOSURE_SERVICES
198 Enclosures are devices sitting on or in SCSI backplanes that
199 manage devices. If you have a disk cage, the chances are that
200 it has an enclosure device. Selecting this option will just allow
201 certain enclosure conditions to be reported and is not required.
203 config SCSI_CONSTANTS
204 bool "Verbose SCSI error reporting (kernel size +=75K)"
207 The error messages regarding your SCSI hardware will be easier to
208 understand if you say Y here; it will enlarge your kernel by about
209 75 KB. If in doubt, say Y.
212 bool "SCSI logging facility"
215 This turns on a logging facility that can be used to debug a number
216 of SCSI related problems.
218 If you say Y here, no logging output will appear by default, but you
219 can enable logging by saying Y to "/proc file system support" and
220 "Sysctl support" below and executing the command
222 echo <bitmask> > /proc/sys/dev/scsi/logging_level
224 where <bitmask> is a four byte value representing the logging type
225 and logging level for each type of logging selected.
227 There are a number of logging types and you can find them in the
228 source at <file:drivers/scsi/scsi_logging.h>. The logging levels
229 are also described in that file and they determine the verbosity of
230 the logging for each logging type.
232 If you say N here, it may be harder to track down some types of SCSI
233 problems. If you say Y here your kernel will be somewhat larger, but
234 there should be no noticeable performance impact as long as you have
237 config SCSI_SCAN_ASYNC
238 bool "Asynchronous SCSI scanning"
241 The SCSI subsystem can probe for devices while the rest of the
242 system continues booting, and even probe devices on different
243 busses in parallel, leading to a significant speed-up.
245 You can override this choice by specifying "scsi_mod.scan=sync"
246 or async on the kernel's command line.
248 Note that this setting also affects whether resuming from
249 system suspend will be performed asynchronously.

313 The iSCSI Driver provides a host with the ability to access storage
314 through an IP network. The driver uses the iSCSI protocol to transport
315 SCSI requests and responses over a TCP/IP network between the host
316 (the "initiator") and "targets". Architecturally, the iSCSI driver
317 combines with the host's TCP/IP stack, network drivers, and Network
318 Interface Card (NIC) to provide the same functions as a SCSI or a

1056 capable (875A, 895A, 896, 1010-33, 1010-66, 1000).
1058 When set to 0, the driver will program the chip to only perform
1059 32-bit DMA. When set to 1, the chip will be able to perform DMA
1060 to addresses up to 1TB. When set to 2, the driver supports the
1061 full 64-bit DMA address range, but can only address 16 segments
1062 of 4 GB each. This limits the total addressable range to 64 GB.
1064 Most machines with less than 4GB of memory should use a setting
1065 of 0 for best performance. If your machine has 4GB of memory
1066 or more, you should set this option to 1 (the default).
1068 The still experimental value 2 (64 bit DMA addressing with 16
1069 x 4GB segments limitation) can be used on systems that require
1070 PCI address bits past bit 39 to be set for the addressing of

1142 tristate "NCR Quad 720 MCA SCSI support"
1143 depends on MCA && SCSI
1144 select SCSI_SPI_ATTRS
1146 This is a driver for the MicroChannel Quad 720 card produced by
1147 NCR and commonly used in 345x/35xx/4100 class machines. It always
1148 tries to negotiate sync and uses tag command queueing.
1150 Unless you have an NCR manufactured machine, the chances are that
1151 you do not have this SCSI card, so say N.
1153 config SCSI_NCR53C8XX_DEFAULT_TAGS
1154 int "default tagged command queue depth"
1155 depends on SCSI_ZALON || SCSI_NCR_Q720
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).
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.
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.
1177 There is no safe option other than using good SCSI devices.
1179 config SCSI_NCR53C8XX_MAX_TAGS
1180 int "maximum number of queued commands"
1181 depends on SCSI_ZALON || SCSI_NCR_Q720
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.
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.
1194 There is no safe option and the default answer is recommended.
1196 config SCSI_NCR53C8XX_SYNC
1197 int "synchronous transfers frequency in MHz"
1198 depends on SCSI_ZALON || SCSI_NCR_Q720
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.
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.
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
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.
1227 There is no safe option other than using good cabling, right
1228 terminations and SCSI conformant devices.
1230 config SCSI_NCR53C8XX_NO_DISCONNECT
1231 bool "not allow targets to disconnect"
1232 depends on (SCSI_ZALON || SCSI_NCR_Q720) && SCSI_NCR53C8XX_DEFAULT_TAGS=0
1234 This option is only provided for safety if you suspect some SCSI
1235 device of yours to not support properly the target-disconnect
1236 feature. In that case, you would say Y here. In general however, to
1237 not allow targets to disconnect is not reasonable if there is more
1238 than 1 device on a SCSI bus. The normal answer therefore is N.

1327 This is support for the sym53c416 SCSI host adapter, the SCSI
1328 adapter that comes with some HP scanners. This driver requires that
1329 the sym53c416 is configured first using some sort of PnP
1330 configuration program (e.g. isapnp) or by a PnP aware BIOS. If you
1331 are using isapnp then you need to compile this driver as a module
1332 and then load it using insmod after isapnp has run. The parameters
1333 of the configured card(s) should be passed to the driver. The format

1345 This driver supports PCI SCSI host adapters based on the ASIC
1346 TRM-S1040 chip, e.g Tekram DC395(U/UW/F) and DC315(U) variants.
1348 This driver works, but is still in experimental status. So better
1349 have a bootable disk and a backup in case of emergency.

1362 chip, e.g. Tekram DC390(T), DawiControl 2974 and some onboard
1363 PCscsi/PCnet (Am53/79C974) solutions.
1364 This is a new implementation base on the generic esp_scsi driver.

1395 This is support for the UltraStor 14F and 34F SCSI-2 host adapters.
1396 The source at <file:drivers/scsi/u14-34f.c> contains some
1397 information about this hardware. If the driver doesn't work out of
1398 the box, you may have to change some settings in

1408 config SCSI_U14_34F_TAGGED_QUEUE
1409 bool "enable tagged command queueing"
1410 depends on SCSI_U14_34F
1412 This is a feature of SCSI-2 which improves performance: the host
1413 adapter can send several SCSI commands to a device's queue even if
1414 previous commands haven't finished yet.
1415 This is equivalent to the "u14-34f=tc:y" boot option.
1417 config SCSI_U14_34F_LINKED_COMMANDS
1418 bool "enable elevator sorting"
1419 depends on SCSI_U14_34F
1421 This option enables elevator sorting for all probed SCSI disks and
1422 CD-ROMs. It definitely reduces the average seek distance when doing
1423 random seeks, but this does not necessarily result in a noticeable
1424 performance improvement: your mileage may vary...
1425 This is equivalent to the "u14-34f=lc:y" boot option.
1427 config SCSI_U14_34F_MAX_TAGS
1428 int "maximum number of queued commands"
1429 depends on SCSI_U14_34F
1432 This specifies how many SCSI commands can be maximally queued for
1433 each probed SCSI device. You should reduce the default value of 8
1434 only if you have disks with buggy or limited tagged command support.
1435 Minimum is 2 and maximum is 14. This value is also the window size
1436 used by the elevator sorting option above. The effective value used
1437 by the driver for each probed SCSI device is reported at boot time.
1438 This is equivalent to the "u14-34f=mq:8" boot option.

1474 SCSI controllers (based on WD33C296A chip).
1477 tristate "SCSI debugging host and device simulator"
1481 This pseudo driver simulates one or more hosts (SCSI initiators),
1482 each with one or more targets, each with one or more logical units.
1483 Defaults to one of each, creating a small RAM disk device. Many
1484 parameters found in the /sys/bus/pseudo/drivers/scsi_debug
1485 directory can be tweaked at run time.
1486 See <http://sg.danny.cz/sg/sdebug26.html> for more information.

1502 int "maximum synchronous transfer rate (MB/s) (0 = async)"
1503 depends on SCSI_MESH
1506 On Power Macintoshes (and clones) where the MESH SCSI bus adaptor
1507 drives a bus which is entirely internal to the machine (such as the
1508 7500, 7600, 8500, etc.), the MESH is capable of synchronous
1509 operation at up to 10 MB/s. On machines where the SCSI bus
1510 controlled by the MESH can have external devices connected, it is
1511 usually rated at 5 MB/s. 5 is a safe value here unless you know the
1512 MESH SCSI bus is internal only; in that case you can say 10. Say 0
1513 to disable synchronous operation.

1522 depends on PPC32 && PPC_PMAC && SCSI
1524 On Power Macintoshes (and clones) with two SCSI buses, the external
1525 SCSI bus is usually controlled by a 53C94 SCSI bus adaptor. Older
1526 machines which only have one SCSI bus, such as the 7200, also use
1527 the 53C94. Say Y to include support for the 53C94.
