29 If you want to use a SCSI hard disk, SCSI tape drive, SCSI CD-ROM or
30 any other SCSI device under Linux, say Y and make sure that you know
31 the name of your SCSI host adapter (the card inside your computer
32 that "speaks" the SCSI protocol, also called SCSI controller),
33 because you will be asked for it.
34
35 You also need to say Y here if you have a device which speaks
36 the SCSI protocol. Examples of this include the parallel port
37 version of the IOMEGA ZIP drive, USB storage devices, Fibre
93c164af 38 Channel, and FireWire storage.

148 For other devices, it's possible that you'll have to write the

220 There are a number of logging types and you can find them in the

314 SCSI requests and responses over a TCP/IP network between the host
315 (the "initiator") and "targets". Architecturally, the iSCSI driver
316 combines with the host's TCP/IP stack, network drivers, and Network

925 capable (875A, 895A, 896, 1010-33, 1010-66, 1000).
926
927 When set to 0, the driver will program the chip to only perform
928 32-bit DMA. When set to 1, the chip will be able to perform DMA
929 to addresses up to 1TB. When set to 2, the driver supports the
930 full 64-bit DMA address range, but can only address 16 segments
931 of 4 GB each. This limits the total addressable range to 64 GB.
932
933 Most machines with less than 4GB of memory should use a setting
934 of 0 for best performance. If your machine has 4GB of memory
935 or more, you should set this option to 1 (the default).
936
937 The still experimental value 2 (64 bit DMA addressing with 16
938 x 4GB segments limitation) can be used on systems that require
939 PCI address bits past bit 39 to be set for the addressing of
940 memory using PCI DAC cycles.

1017 "Tagged command queuing" is a feature of SCSI-2 which improves
1018 performance: the host adapter can send several SCSI commands to a
1019 device's queue even if previous commands haven't finished yet.
1020 Because the device is intelligent, it can optimize its operations
1021 (like head positioning) based on its own request queue. Some SCSI
1022 devices don't implement this properly; if you want to disable this
1023 feature, enter 0 or 1 here (it doesn't matter which).
1024
1025 The default value is 8 and should be supported by most hard disks.
1026 This value can be overridden from the boot command line using the
1027 'tags' option as follows (example):
1028 'ncr53c8xx=tags:4/t2t3q16/t0u2q10' will set default queue depth to
1029 4, set queue depth to 16 for target 2 and target 3 on controller 0
1030 and set queue depth to 10 for target 0 / lun 2 on controller 1.
1031
1032 The normal answer therefore is to go with the default 8 and to use
1033 a boot command line option for devices that need to use a different
1034 command queue depth.
1035
1036 There is no safe option other than using good SCSI devices.

1043 This option allows you to specify the maximum number of commands

1046 Modern hard disks are able to support 64 tags and even more, but
1047 do not seem to be faster when more than 32 tags are being used.
1048
1049 So, the normal answer here is to go with the default value 32 unless
1050 you are using very large hard disks with large cache (>= 1 MB) that
1051 are able to take advantage of more than 32 tagged commands.
1052

1060 The SCSI Parallel Interface-2 Standard defines 5 classes of transfer
1061 rates: FAST-5, FAST-10, FAST-20, FAST-40 and FAST-80. The numbers
1062 are respectively the maximum data transfer rates in mega-transfers
1063 per second for each class. For example, a FAST-20 Wide 16 device is
1064 able to transfer data at 20 million 16 bit packets per second for a
1065 total rate of 40 MB/s.
1066
1067 You may specify 0 if you want to only use asynchronous data
1068 transfers. This is the safest and slowest option. Otherwise, specify
1069 a value between 5 and 80, depending on the capability of your SCSI
1070 controller. The higher the number, the faster the data transfer.
1071 Note that 80 should normally be ok since the driver decreases the
1072 value automatically according to the controller's capabilities.
1073
1074 Your answer to this question is ignored for controllers with NVRAM,
1075 since the driver will get this information from the user set-up. It
1076 also can be overridden using a boot setup option, as follows
1077 (example): 'ncr53c8xx=sync:12' will allow the driver to negotiate
1078 for FAST-20 synchronous data transfer (20 mega-transfers per
1079 second).
1080
1081 The normal answer therefore is not to go with the default but to
1082 select the maximum value 80 allowing the driver to use the maximum
1083 value supported by each controller. If this causes problems with
1084 your SCSI devices, you should come back and decrease the value.
1085
1086 There is no safe option other than using good cabling, right
1087 terminations and SCSI conformant devices.

1374 If you have an Atari with built-in NCR5380 SCSI controller (TT,
1375 Falcon, ...) say Y to get it supported. Of course also, if you have
1376 a compatible SCSI controller (e.g. for Medusa).

1379 be called atari_scsi. If you also enable NVRAM support, the SCSI
1380 host's ID is taken from the setting in TT RTC NVRAM.

1382 This driver supports both styles of NCR integration into the
1383 system: the TT style (separate DMA), and the Falcon style (via
1384 ST-DMA, replacing ACSI). It does NOT support other schemes, like
1385 in the Hades (without DMA).
