Do not compile this driver as a module if your root file system (the one containing the directory /) is located on a SCSI disk. In this case, do not compile the driver for your SCSI host adapter (below) as a module either. config CHR_DEV_ST tristate "SCSI tape support" depends on SCSI ---help--- If you want to use a SCSI tape drive under Linux, say Y and read the SCSI-HOWTO, available from , and in the kernel source. This is NOT for SCSI CD-ROMs. To compile this driver as a module, choose M here and read . The module will be called st. config CHR_DEV_OSST tristate "SCSI OnStream SC-x0 tape support" depends on SCSI ---help--- The OnStream SC-x0 SCSI tape drives cannot be driven by the standard st driver, but instead need this special osst driver and use the /dev/osstX char device nodes (major 206). Via usb-storage, you may be able to drive the USB-x0 and DI-x0 drives as well. Note that there is also a second generation of OnStream tape drives (ADR-x0) that supports the standard SCSI-2 commands for tapes (QIC-157) and can be driven by the standard driver st. For more information, you may have a look at the SCSI-HOWTO and in the kernel source. More info on the OnStream driver may be found on Please also have a look at the standard st docu, as most of it applies to osst as well. To compile this driver as a module, choose M here and read .

This is required to support multisession CDs with old NEC/TOSHIBA cdrom drives (and HP Writers). If you have such a drive and get the first session only, try saying Y here; everybody else says N. config CHR_DEV_SG tristate "SCSI generic support" depends on SCSI ---help--- If you want to use SCSI scanners, synthesizers or CD-writers or just about anything having "SCSI" in its name other than hard disks, CD-ROMs or tapes, say Y here. These won't be supported by the kernel directly, so you need some additional software which knows how to talk to these devices using the SCSI protocol: For scanners, look at SANE (). For CD writer software look at Cdrtools () and for burning a "disk at once": CDRDAO (). Cdparanoia is a high quality digital reader of audio CDs (). For other devices, it's possible that you'll have to write the driver software yourself. Please read the file for more information. To compile this driver as a module, choose M here and read . The module will be called sg. If unsure, say N. config CHR_DEV_SCH tristate "SCSI media changer support" depends on SCSI ---help--- This is a driver for SCSI media changers. Most common devices are tape libraries and MOD/CDROM jukeboxes. *Real* jukeboxes, you don't need this for those tiny 6-slot cdrom changers. Media changers are listed as "Type: Medium Changer" in /proc/scsi/scsi. If you have such hardware and want to use it with linux, say Y here. Check for details. If you want to compile this as a module ( = code which can be inserted in and removed from the running kernel whenever you want), say M here and read and . The module will be called ch.o. If unsure, say N. config SCSI_ENCLOSURE tristate "SCSI Enclosure Support" depends on SCSI && ENCLOSURE_SERVICES help Enclosures are devices sitting on or in SCSI backplanes that manage devices. If you have a disk cage, the chances are that it has an enclosure device. Selecting this option will just allow certain enclosure conditions to be reported and is not required. config SCSI_MULTI_LUN bool "Probe all LUNs on each SCSI device" depends on SCSI help Some devices support more than one LUN (Logical Unit Number) in order to allow access to several media, e.g. CD jukebox, USB card reader, mobile phone in mass storage mode. This option forces the kernel to probe for all LUNs by default. This setting can be overriden by max_luns boot/module parameter. Note that this option does not affect devices conforming to SCSI-3 or higher as they can explicitely report their number of LUNs. It is safe to say Y here unless you have one of those rare devices which reacts in an unexpected way when probed for multiple LUNs. config SCSI_CONSTANTS bool "Verbose SCSI error reporting (kernel size +=12K)" depends on SCSI help The error messages regarding your SCSI hardware will be easier to understand if you say Y here; it will enlarge your kernel by about 12 KB. If in doubt, say Y. config SCSI_LOGGING bool "SCSI logging facility" depends on SCSI ---help--- This turns on a logging facility that can be used to debug a number of SCSI related problems. If you say Y here, no logging output will appear by default, but you can enable logging by saying Y to "/proc file system support" and "Sysctl support" below and executing the command echo > /proc/sys/dev/scsi/logging_level where is a four byte value representing the logging type and logging level for each type of logging selected. There are a number of logging types and you can find them in the source at . The logging levels are also described in that file and they determine the verbosity of the logging for each logging type. If you say N here, it may be harder to track down some types of SCSI problems. If you say Y here your kernel will be somewhat larger, but there should be no noticeable performance impact as long as you have logging turned off. config SCSI_SCAN_ASYNC bool "Asynchronous SCSI scanning" depends on SCSI help The SCSI subsystem can probe for devices while the rest of the system continues booting, and even probe devices on different busses in parallel, leading to a significant speed-up. If you have built SCSI as modules, enabling this option can be a problem as the devices may not have been found by the time your system expects them to have been. You can load the scsi_wait_scan module to ensure that all scans have completed. If you build your SCSI drivers into the kernel, then everything will work fine if you say Y here. You can override this choice by specifying "scsi_mod.scan=sync" or async on the kernel's command line. config SCSI_WAIT_SCAN tristate # No prompt here, this is an invisible symbol. default m depends on SCSI depends on MODULES # scsi_wait_scan is a loadable module which waits until all the async scans are # complete. The idea is to use it in initrd/ initramfs scripts. You modprobe # it after all the modprobes of the root SCSI drivers and it will wait until # they have all finished scanning their buses before allowing the boot to # proceed. (This method is not applicable if targets boot independently in # parallel with the initiator, or with transports with non-deterministic target # discovery schemes, or if a transport driver does not support scsi_wait_scan.) # # This symbol is not exposed as a prompt because little is to be gained by # disabling it, whereas people who accidentally switch it off may wonder why # their mkinitrd gets into trouble. menu "SCSI Transports" depends on SCSI config SCSI_SPI_ATTRS tristate "Parallel SCSI (SPI) Transport Attributes" depends on SCSI help If you wish to export transport-specific information about each attached SCSI device to sysfs, say Y.

Adaptec, Inc. is writing a new driver to take the place of this one, and it is recommended that whenever possible, people should use the new Adaptec written driver instead of this one. This driver will eventually be phased out entirely. This is support for the various aic7xxx based Adaptec SCSI controllers. These include the 274x EISA cards; 284x VLB cards; 2902, 2910, 293x, 294x, 394x, 3985 and several other PCI and motherboard based SCSI controllers from Adaptec. It does not support the AAA-13x RAID controllers from Adaptec, nor will it likely ever support them. It does not support the 2920 cards from Adaptec that use the Future Domain SCSI controller chip. For those cards, you need the "Future Domain 16xx SCSI support" driver. In general, if the controller is based on an Adaptec SCSI controller chip from the aic777x series or the aic78xx series, this driver should work. The only exception is the 7810 which is specifically not supported (that's the RAID controller chip on the AAA-13x cards). Note that the AHA2920 SCSI host adapter is *not* supported by this driver; choose "Future Domain 16xx SCSI support" instead if you have one of those.

These machines have an MCA bus, so you need to answer Y to "MCA support" as well and read . If the adapter isn't found during boot (a common problem for models 56, 57, 76, and 77) you'll need to use the 'ibmmcascsi=' kernel option, where is the id of the SCSI subsystem (usually 7, but if that doesn't work check your reference diskette). Owners of model 95 with a LED-matrix-display can in addition activate some activity info like under OS/2, but more informative, by setting 'ibmmcascsi=display' as an additional kernel parameter.

To compile this driver as a module, choose M here: the module will be called ibmmca. config IBMMCA_SCSI_ORDER_STANDARD bool "Standard SCSI-order" depends on SCSI_IBMMCA ---help--- In the PC-world and in most modern SCSI-BIOS-setups, SCSI-hard disks are assigned to the drive letters, starting with the lowest SCSI-id (physical number -- pun) to be drive C:, as seen from DOS and similar operating systems. When looking into papers describing the ANSI-SCSI-standard, this assignment of drives appears to be wrong. The SCSI-standard follows a hardware-hierarchy which says that id 7 has the highest priority and id 0 the lowest. Therefore, the host adapters are still today everywhere placed as SCSI-id 7 by default. In the SCSI-standard, the drive letters express the priority of the disk. C: should be the hard disk, or a partition on it, with the highest priority. This must therefore be the disk with the highest SCSI-id (e.g. 6) and not the one with the lowest! IBM-BIOS kept the original definition of the SCSI-standard as also industrial- and process-control-machines, like VME-CPUs running under realtime-OSes (e.g. LynxOS, OS9) do. If you like to run Linux on your MCA-machine with the same assignment of hard disks as seen from e.g. DOS or OS/2 on your machine, which is in addition conformant to the SCSI-standard, you must say Y here. This is also necessary for MCA-Linux users who want to keep downward compatibility to older releases of the IBM-MCA-SCSI-driver (older than driver-release 2.00 and older than June 1997). If you like to have the lowest SCSI-id assigned as drive C:, as modern SCSI-BIOSes do, which does not conform to the standard, but is widespread and common in the PC-world of today, you must say N here. If unsure, say Y. config IBMMCA_SCSI_DEV_RESET bool "Reset SCSI-devices at boottime" depends on SCSI_IBMMCA ---help--- By default, SCSI-devices are reset when the machine is powered on. However, some devices exist, like special-control-devices, SCSI-CNC-machines, SCSI-printer or scanners of older type, that do not reset when switched on. If you say Y here, each device connected to your SCSI-bus will be issued a reset-command after it has been probed, while the kernel is booting. This may cause problems with more modern devices, like hard disks, which do not appreciate these reset commands, and can cause your system to hang. So say Y only if you know that one of your older devices needs it; N is the safe answer. config SCSI_IPS tristate "IBM ServeRAID support" depends on PCI && SCSI ---help--- This is support for the IBM ServeRAID hardware RAID controllers.

Some parallel port chipsets are slower than their motherboard, and so we have to control the state of the chipset's FIFO queue every now and then to avoid data loss. This will be done if you say Y here. Generally, saying Y is the safe option and slows things down a bit. config SCSI_IZIP_SLOW_CTR bool "ppa/imm option - Assume slow parport control register" depends on SCSI_PPA || SCSI_IMM help Some parallel ports are known to have excessive delays between changing the parallel port control register and good data being available on the parallel port data/status register. This option forces a small delay (1.0 usec to be exact) after changing the control register to let things settle out. Enabling this option may result in a big drop in performance but some very old parallel ports (found in 386 vintage machines) will not work properly. Generally, saying N is fine. config SCSI_NCR53C406A tristate "NCR53c406a SCSI support" depends on ISA && SCSI help This is support for the NCR53c406a SCSI host adapter.

It also supports the subset of LSI53C10XX Ultra-160 controllers that are based on the SYM53C8XX SCRIPTS language. It does not support LSI53C10XX Ultra-320 PCI-X SCSI controllers; you need to use the Fusion MPT driver for that. Please read for more information. config SCSI_SYM53C8XX_DMA_ADDRESSING_MODE int "DMA addressing mode" depends on SCSI_SYM53C8XX_2 default "1" ---help--- This option only applies to PCI-SCSI chips that are PCI DAC capable (875A, 895A, 896, 1010-33, 1010-66, 1000). When set to 0, the driver will program the chip to only perform 32-bit DMA. When set to 1, the chip will be able to perform DMA to addresses up to 1TB. When set to 2, the driver supports the full 64-bit DMA address range, but can only address 16 segments of 4 GB each. This limits the total addressable range to 64 GB. Most machines with less than 4GB of memory should use a setting of 0 for best performance. If your machine has 4GB of memory or more, you should set this option to 1 (the default). The still experimental value 2 (64 bit DMA addressing with 16 x 4GB segments limitation) can be used on systems that require PCI address bits past bit 39 to be set for the addressing of memory using PCI DAC cycles. config SCSI_SYM53C8XX_DEFAULT_TAGS int "Default tagged command queue depth" depends on SCSI_SYM53C8XX_2 default "16" help This is the default value of the command queue depth the driver will announce to the generic SCSI layer for devices that support tagged command queueing. This value can be changed from the boot command line. This is a soft limit that cannot exceed CONFIG_SCSI_SYM53C8XX_MAX_TAGS. config SCSI_SYM53C8XX_MAX_TAGS int "Maximum number of queued commands" depends on SCSI_SYM53C8XX_2 default "64" help This option allows you to specify the maximum number of commands that can be queued to any device, when tagged command queuing is possible. The driver supports up to 256 queued commands per device. This value is used as a compiled-in hard limit. config SCSI_SYM53C8XX_MMIO bool "Use memory mapped IO" depends on SCSI_SYM53C8XX_2 default y help Memory mapped IO is faster than Port IO. Most people should answer Y here, but some machines may have problems. If you have to answer N here, please report the problem to the maintainer. config SCSI_IPR tristate "IBM Power Linux RAID adapter support" depends on PCI && SCSI && ATA select FW_LOADER ---help--- This driver supports the IBM Power Linux family RAID adapters. This includes IBM pSeries 5712, 5703, 5709, and 570A, as well as IBM iSeries 5702, 5703, 5709, and 570A. config SCSI_IPR_TRACE bool "enable driver internal trace" depends on SCSI_IPR default y help If you say Y here, the driver will trace all commands issued to the adapter. Performance impact is minimal. Trace can be dumped using /sys/bus/class/scsi_host/hostXX/trace. config SCSI_IPR_DUMP bool "enable adapter dump support" depends on SCSI_IPR default y help If you say Y here, the driver will support adapter crash dump. If you enable this support, the iprdump daemon can be used to capture adapter failure analysis information. config SCSI_ZALON tristate "Zalon SCSI support" depends on GSC && SCSI select SCSI_SPI_ATTRS help The Zalon is a GSC/HSC bus interface chip that sits between the PA-RISC processor and the NCR 53c720 SCSI controller on C100, C110, J200, J210 and some D, K & R-class machines. It's also used on the add-in Bluefish, Barracuda & Shrike SCSI cards. Say Y here if you have one of these machines or cards. config SCSI_NCR_Q720 tristate "NCR Quad 720 MCA SCSI support" depends on MCA && SCSI select SCSI_SPI_ATTRS help This is a driver for the MicroChannel Quad 720 card produced by NCR and commonly used in 345x/35xx/4100 class machines. It always tries to negotiate sync and uses tag command queueing. Unless you have an NCR manufactured machine, the chances are that you do not have this SCSI card, so say N. config SCSI_NCR53C8XX_DEFAULT_TAGS int "default tagged command queue depth" depends on SCSI_ZALON || SCSI_NCR_Q720 default "8" ---help--- "Tagged command queuing" is a feature of SCSI-2 which improves performance: the host adapter can send several SCSI commands to a device's queue even if previous commands haven't finished yet. Because the device is intelligent, it can optimize its operations (like head positioning) based on its own request queue. Some SCSI devices don't implement this properly; if you want to disable this feature, enter 0 or 1 here (it doesn't matter which). The default value is 8 and should be supported by most hard disks. This value can be overridden from the boot command line using the 'tags' option as follows (example): 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to 4, set queue depth to 16 for target 2 and target 3 on controller 0 and set queue depth to 10 for target 0 / lun 2 on controller 1. The normal answer therefore is to go with the default 8 and to use a boot command line option for devices that need to use a different command queue depth. There is no safe option other than using good SCSI devices. config SCSI_NCR53C8XX_MAX_TAGS int "maximum number of queued commands" depends on SCSI_ZALON || SCSI_NCR_Q720 default "32" ---help--- This option allows you to specify the maximum number of commands that can be queued to any device, when tagged command queuing is possible. The default value is 32. Minimum is 2, maximum is 64. Modern hard disks are able to support 64 tags and even more, but do not seem to be faster when more than 32 tags are being used. So, the normal answer here is to go with the default value 32 unless you are using very large hard disks with large cache (>= 1 MB) that are able to take advantage of more than 32 tagged commands. There is no safe option and the default answer is recommended. config SCSI_NCR53C8XX_SYNC int "synchronous transfers frequency in MHz" depends on SCSI_ZALON || SCSI_NCR_Q720 default "20" ---help--- The SCSI Parallel Interface-2 Standard defines 5 classes of transfer rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80. The numbers are respectively the maximum data transfer rates in mega-transfers per second for each class. For example, a FAST-20 Wide 16 device is able to transfer data at 20 million 16 bit packets per second for a total rate of 40 MB/s. You may specify 0 if you want to only use asynchronous data transfers. This is the safest and slowest option. Otherwise, specify a value between 5 and 80, depending on the capability of your SCSI controller. The higher the number, the faster the data transfer. Note that 80 should normally be ok since the driver decreases the value automatically according to the controller's capabilities. Your answer to this question is ignored for controllers with NVRAM, since the driver will get this information from the user set-up. It also can be overridden using a boot setup option, as follows (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate for FAST-20 synchronous data transfer (20 mega-transfers per second). The normal answer therefore is not to go with the default but to select the maximum value 80 allowing the driver to use the maximum value supported by each controller. If this causes problems with your SCSI devices, you should come back and decrease the value. There is no safe option other than using good cabling, right terminations and SCSI conformant devices. config SCSI_NCR53C8XX_NO_DISCONNECT bool "not allow targets to disconnect" depends on (SCSI_ZALON || SCSI_NCR_Q720) && SCSI_NCR53C8XX_DEFAULT_TAGS=0 help This option is only provided for safety if you suspect some SCSI device of yours to not support properly the target-disconnect feature. In that case, you would say Y here. In general however, to not allow targets to disconnect is not reasonable if there is more than 1 device on a SCSI bus. The normal answer therefore is N. config SCSI_PAS16 tristate "PAS16 SCSI support" depends on ISA && SCSI select SCSI_SPI_ATTRS ---help--- This is support for a SCSI host adapter. It is explained in section 3.10 of the SCSI-HOWTO, available from . If it doesn't work out of the box, you may have to change some settings in .

This driver requires that the sym53c416 is configured first using some sort of PnP configuration program (e.g. isapnp) or by a PnP aware BIOS. If you are using isapnp then you need to compile this driver as a module and then load it using insmod after isapnp has run. The parameters of the configured card(s) should be passed to the driver. The format is: insmod sym53c416 sym53c416=, [sym53c416_1=,] To compile this driver as a module, choose M here: the module will be called sym53c416. config SCSI_DC395x tristate "Tekram DC395(U/UW/F) and DC315(U) SCSI support (EXPERIMENTAL)" depends on PCI && SCSI && EXPERIMENTAL ---help--- This driver supports PCI SCSI host adapters based on the ASIC TRM-S1040 chip, e.g Tekram DC395(U/UW/F) and DC315(U) variants. This driver works, but is still in experimental status. So better have a bootable disk and a backup in case of emergency. Documentation can be found in .

This is equivalent to the "u14-34f=tc:y" boot option. config SCSI_U14_34F_LINKED_COMMANDS bool "enable elevator sorting" depends on SCSI_U14_34F help This option enables elevator sorting for all probed SCSI disks and CD-ROMs. It definitely reduces the average seek distance when doing random seeks, but this does not necessarily result in a noticeable performance improvement: your mileage may vary... This is equivalent to the "u14-34f=lc:y" boot option. config SCSI_U14_34F_MAX_TAGS int "maximum number of queued commands" depends on SCSI_U14_34F default "8" help This specifies how many SCSI commands can be maximally queued for each probed SCSI device. You should reduce the default value of 8 only if you have disks with buggy or limited tagged command support. Minimum is 2 and maximum is 14. This value is also the window size used by the elevator sorting option above. The effective value used by the driver for each probed SCSI device is reported at boot time.

It defaults to one host adapter with one dummy SCSI disk. Each dummy disk uses kernel RAM as storage (i.e. it is a ramdisk). To save space when multiple dummy disks are simulated, they share the same kernel RAM for their storage. See for more information. This driver is primarily of use to those testing the SCSI and block subsystems. If unsure, say N. config SCSI_MESH tristate "MESH (Power Mac internal SCSI) support" depends on PPC32 && PPC_PMAC && SCSI help Many Power Macintoshes and clones have a MESH (Macintosh Enhanced SCSI Hardware) SCSI bus adaptor (the 7200 doesn't, but all of the other Power Macintoshes do).

To compile this driver as a module, choose M here: the module will be called mesh. config SCSI_MESH_SYNC_RATE int "maximum synchronous transfer rate (MB/s) (0 = async)" depends on SCSI_MESH default "5" help On Power Macintoshes (and clones) where the MESH SCSI bus adaptor drives a bus which is entirely internal to the machine (such as the 7500, 7600, 8500, etc.), the MESH is capable of synchronous operation at up to 10 MB/s. On machines where the SCSI bus controlled by the MESH can have external devices connected, it is usually rated at 5 MB/s. 5 is a safe value here unless you know the MESH SCSI bus is internal only; in that case you can say 10. Say 0 to disable synchronous operation. config SCSI_MESH_RESET_DELAY_MS int "initial bus reset delay (ms) (0 = no reset)" depends on SCSI_MESH default "4000" config SCSI_MAC53C94 tristate "53C94 (Power Mac external SCSI) support" depends on PPC32 && PPC_PMAC && SCSI help On Power Macintoshes (and clones) with two SCSI buses, the external SCSI bus is usually controlled by a 53C94 SCSI bus adaptor.
