Hannes Reinecke 2dd951ecd5 scsi: Conditionally compile in constants.c 
Instead of having constants.c littered with ifdef statements we should
be moving dummy functions into the header and condintionally compile in
constants.c if selected. And update the Kconfig description to reflect
the actual size difference.

If you want to use a SCSI hard disk, SCSI tape drive, SCSI CD-ROM or
any other SCSI device under Linux, say Y and make sure that you know
the name of your SCSI host adapter (the card inside your computer
that "speaks" the SCSI protocol, also called SCSI controller),
because you will be asked for it.
You also need to say Y here if you have a device which speaks
the SCSI protocol. Examples of this include the parallel port
version of the IOMEGA ZIP drive, USB storage devices, Fibre
Channel, and FireWire storage.
To compile this driver as a module, choose M here and read
<file:Documentation/scsi/scsi.txt>.
The module will be called scsi_mod.
However, do not compile this as a module if your root file system
(the one containing the directory /) is located on a SCSI device.

the IOMEGA ZIP drive, say Y and read the SCSI-HOWTO,
the Disk-HOWTO and the Multi-Disk-HOWTO, available from
<http://www.tldp.org/docs.html#howto>. This is NOT for SCSI

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
<http://www.tldp.org/docs.html#howto> and
<file:Documentation/scsi/osst.txt> in the kernel source.
More info on the OnStream driver may be found on
<http://sourceforge.net/projects/osst/>
Please also have a look at the standard st docu, as most of it
applies to osst as well.

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 (<http://www.sane-project.org/>). For CD
writer software look at Cdrtools
(<http://cdrecord.berlios.de/private/cdrecord.html>)
and for burning a "disk at once": CDRDAO
(<http://cdrdao.sourceforge.net/>). Cdparanoia is a high
quality digital reader of audio CDs (<http://www.xiph.org/paranoia/>).
For other devices, it's possible that you'll have to write the
driver software yourself. Please read the file
<file:Documentation/scsi/scsi-generic.txt> for more information.
To compile this driver as a module, choose M here and read
<file:Documentation/scsi/scsi.txt>. The module will be called sg.
If unsure, say N.

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 <file:Documentation/scsi/scsi-changer.txt> 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 <file:Documentation/kbuild/modules.txt> and

config SCSI_CONSTANTS
bool "Verbose SCSI error reporting (kernel size +=75K)"

The error messages regarding your SCSI hardware will be easier to
understand if you say Y here; it will enlarge your kernel by about
75 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 <bitmask> > /proc/sys/dev/scsi/logging_level
where <bitmask> 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 <file:drivers/scsi/scsi_logging.h>. 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.
Note that this setting also affects whether resuming from
system suspend will be performed asynchronously.

The iSCSI Driver provides a host with the ability to access storage
through an IP network. The driver uses the iSCSI protocol to transport
SCSI requests and responses over a TCP/IP network between the host
(the "initiator") and "targets". Architecturally, the iSCSI driver
combines with the host's TCP/IP stack, network drivers, and Network
Interface Card (NIC) to provide the same functions as a SCSI or a
Fibre Channel (FC) adapter driver with a Host Bus Adapter (HBA).

on boards using PIO. Most boards such as the Trantor T130 fit this
category, along with a large number of ISA 8bit controllers shipped
for free with SCSI scanners. If you have a PAS16, T128 or DMX3191
you should select the specific driver for that card rather than
generic 5380 support.

EPP (Enhanced Parallel Port) is a standard for parallel ports which
allows them to act as expansion buses that can handle up to 64
peripheral devices.
Some parallel port chipsets are slower than their motherboard, and
so we have to control the state of the chipset's FIFO queue every

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

Most machines with less than 4GB of memory should use a setting

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

---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

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_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). Say Y to include support for this SCSI
adaptor.
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. Older
machines which only have one SCSI bus, such as the 7200, also use
the 53C94. Say Y to include support for the 53C94.
To compile this driver as a module, choose M here: the
module will be called mac53c94.

config SCSI_ZORRO7XX
tristate "Zorro NCR53c710 SCSI support"
depends on ZORRO && SCSI
select SCSI_SPI_ATTRS
help
Support for various NCR53c710-based SCSI controllers on Zorro
expansion boards for the Amiga.
This includes:
- the Amiga 4091 Zorro III SCSI-2 controller,
- the MacroSystem Development's WarpEngine Amiga SCSI-2 controller
(info at

config ATARI_SCSI
tristate "Atari native SCSI support"
depends on ATARI && SCSI
select SCSI_SPI_ATTRS
select NVRAM
---help---
If you have an Atari with built-in NCR5380 SCSI controller (TT,
Falcon, ...) say Y to get it supported. Of course also, if you have
a compatible SCSI controller (e.g. for Medusa).
To compile this driver as a module, choose M here: the
module will be called atari_scsi.
This driver supports both styles of NCR integration into the
system: the TT style (separate DMA), and the Falcon style (via
ST-DMA, replacing ACSI). It does NOT support other schemes, like
in the Hades (without DMA).
config ATARI_SCSI_TOSHIBA_DELAY
bool "Long delays for Toshiba CD-ROMs"
depends on ATARI_SCSI
help
This option increases the delay after a SCSI arbitration to
accommodate some flaky Toshiba CD-ROM drives. Say Y if you intend to
use a Toshiba CD-ROM drive; otherwise, the option is not needed and
would impact performance a bit, so say N.
config ATARI_SCSI_RESET_BOOT
bool "Reset SCSI-devices at boottime"
depends on ATARI_SCSI
help
Reset the devices on your Atari whenever it boots. This makes the
boot process fractionally longer but may assist recovery from errors
that leave the devices with SCSI operations partway completed.
