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

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

199 Enclosures are devices sitting on or in SCSI backplanes that
200 manage devices. If you have a disk cage, the chances are that
201 it has an enclosure device. Selecting this option will just allow
202 certain enclosure conditions to be reported and is not required.
204 config SCSI_CONSTANTS
205 bool "Verbose SCSI error reporting (kernel size +=75K)"
208 The error messages regarding your SCSI hardware will be easier to
209 understand if you say Y here; it will enlarge your kernel by about
210 75 KB. If in doubt, say Y.
213 bool "SCSI logging facility"
216 This turns on a logging facility that can be used to debug a number
217 of SCSI related problems.
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
223 echo <bitmask> > /proc/sys/dev/scsi/logging_level
225 where <bitmask> is a four byte value representing the logging type
226 and logging level for each type of logging selected.
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.
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
238 config SCSI_SCAN_ASYNC
239 bool "Asynchronous SCSI scanning"
242 The SCSI subsystem can probe for devices while the rest of the
243 system continues booting, and even probe devices on different
244 busses in parallel, leading to a significant speed-up.
246 You can override this choice by specifying "scsi_mod.scan=sync"
247 or async on the kernel's command line.
249 Note that this setting also affects whether resuming from
250 system suspend will be performed asynchronously.

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

951 allows them to act as expansion buses that can handle up to 64
954 Some parallel port chipsets are slower than their motherboard, and
955 so we have to control the state of the chipset's FIFO queue every

963 depends on SCSI_PPA || SCSI_IMM
965 Some parallel ports are known to have excessive delays between
966 changing the parallel port control register and good data being
967 available on the parallel port data/status register. This option
968 forces a small delay (1.0 usec to be exact) after changing the
969 control register to let things settle out. Enabling this option may
970 result in a big drop in performance but some very old parallel ports
971 (found in 386 vintage machines) will not work properly.

1045 PCI-SCSI controllers. It also supports the subset of LSI53C10XX
1046 Ultra-160 controllers that are based on the SYM53C8XX SCRIPTS
1047 language. It does not support LSI53C10XX Ultra-320 PCI-X SCSI
1048 controllers; you need to use the Fusion MPT driver for that.

1053 config SCSI_SYM53C8XX_DMA_ADDRESSING_MODE
1054 int "DMA addressing mode"
1055 depends on SCSI_SYM53C8XX_2
1058 This option only applies to PCI-SCSI chips that are PCI DAC
1059 capable (875A, 895A, 896, 1010-33, 1010-66, 1000).
1061 When set to 0, the driver will program the chip to only perform
1062 32-bit DMA. When set to 1, the chip will be able to perform DMA
1063 to addresses up to 1TB. When set to 2, the driver supports the
1064 full 64-bit DMA address range, but can only address 16 segments
1065 of 4 GB each. This limits the total addressable range to 64 GB.
1067 Most machines with less than 4GB of memory should use a setting
1068 of 0 for best performance. If your machine has 4GB of memory
1069 or more, you should set this option to 1 (the default).
1071 The still experimental value 2 (64 bit DMA addressing with 16
1072 x 4GB segments limitation) can be used on systems that require
1073 PCI address bits past bit 39 to be set for the addressing of
1074 memory using PCI DAC cycles.

1081 This is the default value of the command queue depth the
1082 driver will announce to the generic SCSI layer for devices
1083 that support tagged command queueing. This value can be changed
1084 from the boot command line. This is a soft limit that cannot
1085 exceed CONFIG_SCSI_SYM53C8XX_MAX_TAGS.
1087 config SCSI_SYM53C8XX_MAX_TAGS
1088 int "Maximum number of queued commands"
1089 depends on SCSI_SYM53C8XX_2
1092 This option allows you to specify the maximum number of commands
1093 that can be queued to any device, when tagged command queuing is
1094 possible. The driver supports up to 256 queued commands per device.
1095 This value is used as a compiled-in hard limit.
1097 config SCSI_SYM53C8XX_MMIO
1098 bool "Use memory mapped IO"

1139 The Zalon is a GSC/HSC bus interface chip that sits between the
1140 PA-RISC processor and the NCR 53c720 SCSI controller on C100,
1141 C110, J200, J210 and some D, K & R-class machines. It's also
1142 used on the add-in Bluefish, Barracuda & Shrike SCSI cards.

1145 config SCSI_NCR_Q720
1146 tristate "NCR Quad 720 MCA SCSI support"
1147 depends on MCA && SCSI
1148 select SCSI_SPI_ATTRS
1150 This is a driver for the MicroChannel Quad 720 card produced by
1151 NCR and commonly used in 345x/35xx/4100 class machines. It always
1152 tries to negotiate sync and uses tag command queueing.
1154 Unless you have an NCR manufactured machine, the chances are that
1155 you do not have this SCSI card, so say N.
1157 config SCSI_NCR53C8XX_DEFAULT_TAGS
1158 int "default tagged command queue depth"
1159 depends on SCSI_ZALON || SCSI_NCR_Q720
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).
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.
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.
1181 There is no safe option other than using good SCSI devices.
1183 config SCSI_NCR53C8XX_MAX_TAGS
1184 int "maximum number of queued commands"
1185 depends on SCSI_ZALON || SCSI_NCR_Q720
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.
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.
1198 There is no safe option and the default answer is recommended.
1200 config SCSI_NCR53C8XX_SYNC
1201 int "synchronous transfers frequency in MHz"
1202 depends on SCSI_ZALON || SCSI_NCR_Q720
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.
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.
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
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.
1231 There is no safe option other than using good cabling, right
1232 terminations and SCSI conformant devices.
1234 config SCSI_NCR53C8XX_NO_DISCONNECT
1235 bool "not allow targets to disconnect"
1236 depends on (SCSI_ZALON || SCSI_NCR_Q720) && SCSI_NCR53C8XX_DEFAULT_TAGS=0
1238 This option is only provided for safety if you suspect some SCSI
1239 device of yours to not support properly the target-disconnect
1240 feature. In that case, you would say Y here. In general however, to
1241 not allow targets to disconnect is not reasonable if there is more
1242 than 1 device on a SCSI bus. The normal answer therefore is N.

1329 depends on ISA && SCSI
1331 This is support for the sym53c416 SCSI host adapter, the SCSI
1332 adapter that comes with some HP scanners. This driver requires that
1333 the sym53c416 is configured first using some sort of PnP
1334 configuration program (e.g. isapnp) or by a PnP aware BIOS. If you
1335 are using isapnp then you need to compile this driver as a module

1349 This driver supports PCI SCSI host adapters based on the ASIC
1350 TRM-S1040 chip, e.g Tekram DC395(U/UW/F) and DC315(U) variants.
1352 This driver works, but is still in experimental status. So better
1353 have a bootable disk and a backup in case of emergency.

1365 This driver supports PCI SCSI host adapters based on the Am53C974A
1366 chip, e.g. Tekram DC390(T), DawiControl 2974 and some onboard
1367 PCscsi/PCnet (Am53/79C974) solutions.
1368 This is a new implementation base on the generic esp_scsi driver.
1370 Documentation can be found in <file:Documentation/scsi/tmscsim.txt>.
1372 Note that this driver does NOT support Tekram DC390W/U/F, which are
1373 based on NCR/Symbios chips. Use "NCR53C8XX SCSI support" for those.

1399 This is support for the UltraStor 14F and 34F SCSI-2 host adapters.
1400 The source at <file:drivers/scsi/u14-34f.c> contains some
1401 information about this hardware. If the driver doesn't work out of
1402 the box, you may have to change some settings in

1412 config SCSI_U14_34F_TAGGED_QUEUE
1413 bool "enable tagged command queueing"
1414 depends on SCSI_U14_34F
1416 This is a feature of SCSI-2 which improves performance: the host
1417 adapter can send several SCSI commands to a device's queue even if
1418 previous commands haven't finished yet.
1419 This is equivalent to the "u14-34f=tc:y" boot option.
1421 config SCSI_U14_34F_LINKED_COMMANDS
1422 bool "enable elevator sorting"
1423 depends on SCSI_U14_34F
1425 This option enables elevator sorting for all probed SCSI disks and
1426 CD-ROMs. It definitely reduces the average seek distance when doing
1427 random seeks, but this does not necessarily result in a noticeable
1428 performance improvement: your mileage may vary...
1429 This is equivalent to the "u14-34f=lc:y" boot option.
1431 config SCSI_U14_34F_MAX_TAGS
1432 int "maximum number of queued commands"
1433 depends on SCSI_U14_34F
1436 This specifies how many SCSI commands can be maximally queued for
1437 each probed SCSI device. You should reduce the default value of 8
1438 only if you have disks with buggy or limited tagged command support.
1439 Minimum is 2 and maximum is 14. This value is also the window size
1440 used by the elevator sorting option above. The effective value used
1441 by the driver for each probed SCSI device is reported at boot time.
1442 This is equivalent to the "u14-34f=mq:8" boot option.

1478 SCSI controllers (based on WD33C296A chip).
1481 tristate "SCSI debugging host and device simulator"
1485 This pseudo driver simulates one or more hosts (SCSI initiators),
1486 each with one or more targets, each with one or more logical units.
1487 Defaults to one of each, creating a small RAM disk device. Many
1488 parameters found in the /sys/bus/pseudo/drivers/scsi_debug
1489 directory can be tweaked at run time.
1490 See <http://sg.danny.cz/sg/sdebug26.html> for more information.

1497 Many Power Macintoshes and clones have a MESH (Macintosh Enhanced
1498 SCSI Hardware) SCSI bus adaptor (the 7200 doesn't, but all of the
1499 other Power Macintoshes do). Say Y to include support for this SCSI

1506 int "maximum synchronous transfer rate (MB/s) (0 = async)"
1507 depends on SCSI_MESH
1510 On Power Macintoshes (and clones) where the MESH SCSI bus adaptor
1511 drives a bus which is entirely internal to the machine (such as the
1512 7500, 7600, 8500, etc.), the MESH is capable of synchronous
1513 operation at up to 10 MB/s. On machines where the SCSI bus
1514 controlled by the MESH can have external devices connected, it is
1515 usually rated at 5 MB/s. 5 is a safe value here unless you know the
1516 MESH SCSI bus is internal only; in that case you can say 10. Say 0
1517 to disable synchronous operation.
1519 config SCSI_MESH_RESET_DELAY_MS
1520 int "initial bus reset delay (ms) (0 = no reset)"
1521 depends on SCSI_MESH

1526 depends on PPC32 && PPC_PMAC && SCSI
1528 On Power Macintoshes (and clones) with two SCSI buses, the external
1529 SCSI bus is usually controlled by a 53C94 SCSI bus adaptor. Older
1530 machines which only have one SCSI bus, such as the 7200, also use
1531 the 53C94. Say Y to include support for the 53C94.
